Copyright (C) 1989-2013 Free Software Foundation, Inc. Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file describes recent user-visible changes in groff. Bug fixes are not described. There are more details in the man and info pages. VERSION 1.22.2 ============== Tbl --- o The character `#' can now be used as an eqn delimiter within tables. Eqn --- o A GNU extension delim on has been added to reactivate delimiters which have been disabled with `delim off'. VERSION 1.22.1 ============== (There was no release 1.22.) Groff ----- o A new option `-j' has been added to call the `chem' preprocessor. Tbl --- o Improved line numbering support. Macro Packages -------------- o Support for the `refer' preprocessor has been added to the -mm macro package. o In -me, the `TH' macro was changed for compatibility with line number support in tables. `bl' now works inside of blocks. The behaviour of centered blocks has been improved. Line numbering support has been improved. o The -mom macro package has reached version 2.0, focusing on PDF output with gropdf (using the new `pdfmom' wrapper script). See the file `version-2.html' of the -mom documentation for a list of the many changes. o Some generic Unicode fallback characters (mainly Roman numerals) have been added. Gropdf ------ o A new driver for generating PDF output directly, contributed by Deri James <deri@chuzzlewit.myzen.co.uk>. Note that this driver is written in Perl, thus you need a working Perl installation to run this output device. Pdfmom ------ o A new wrapper around groff that facilitates the production of PDF documents from files formatted with the -mom macros. VERSION 1.21 ============ Troff ----- o The new `lsm' request specifies a macro to be invoked when leading spaces in an input line are encountered (which are removed then). Number registers `lsn' and `lss' hold the number of removed leading spaces and the corresponding horizontal space, respectively. o There is a new warning category `file', enabled by default. The `mso' request emits warnings in this category when the requested macro file does not exist. o The new `class' request assigns a short name to a set of characters which can be referred to in the `cflags' request. This is especially useful to control line-breaking and hyphenation rules in CJK languages. o Three new values for the `cflags' request have been added, which are needed for proper CJK support. 128 prohibit before but allow break after character 256 prohibit after but allow break before character 512 allow break before and after character Tbl --- o A new global option `nowarn' suppresses warnings if tables are longer than the current line width. Afmtodit -------- o New option `-o' to specify the name of the output file. Macro Packages -------------- o A new macro `%U' has been added to the mdoc package to indicate a URL reference within an .Rs/.Re environment. o Rudimentary support for the Japanese script has been added, most suitable for man page handling as output by grotty. The file `ja.tmac' contains the necessary setup to allow line breaks before and after CJK characters (with proper exceptions). Note, however, that no inter-character spacing is implemented yet -- this usually causes many warnings about bad line breaks. VERSION 1.20.1 ============== A packaging error made it necessary to publish this release. No user-visible changes. VERSION 1.20 ============ Groff ----- o XHTML support has been added to grohtml and can be specified by -Txhtml. This option also utilizes the MathML capability of eqn and combines the outputs of both in the final XHTML file. Users can also specify the `-P-V' option together with `-Txhtml' in groff. This has the effect of creating an XHTML validator button at the bottom of each page. o Some options have been added to control a new preprocessor, `preconv' (see below): `-k' activates it, `-K' sets the input encoding, and `-D' sets the default encoding. o A new environment variable `GROFF_ENCODING' sets the encoding of input files; it implies command option `-k'. Troff ----- o Two new requests `device' and `devicem' have been added which are equivalents to the \X and \Y escapes, respectively. o A new read-only number register `.br' is available which is set to 1 if a macro is called as .foo and to 0 if called as 'foo. This allows to reliably modify requests. .als bp@orig bp .de bp . tm before bp . ie \\n[.br] .bp@orig . el 'bp@orig . tm after bp .. o A new request `fzoom' has been added to adjust the optical size of a font in relation to the others. The zoom factor is given in integer multiples of 1/1000th. In the following example, the CR font is magnified by 10% (the zoom factor is 1.1). .fam P .fzoom CR 1100 .ps 12 Palatino and \f[CR]Courier\f[] The new number register `.zoom' holds the zoom value of the current font, in multiples of 1/1000th. o The `cflags' request has been extended with a new flag value 64, to be used in combination with values 2 (break before character) and 4 (break after character). If set, the hyphenation codes of the surrounding characters are ignored. o A new debugging request, `pev', has been added to print all of the current known environments to stderr. It first prints the state of the current environment, then iterates through all of the known environments, printing each except the one that is current. o A new escape `\$^' has been added. It represents the parameters of a macro as if they were an argument to the `ds' request. This is used by `trace.tmac'. o A new read-only number register `.O' is available which returns the current suppression level as set by the `\O' escape. o The space width emitted by the `\|' and `\^' escape sequences can be controlled on a per-font basis. If there is a glyph named `\|' or `\^', respectively (note the leading backslash), defined in the current font file, use this glyph's width instead of the default value. This behaviour is not new, but hasn't been documented before. Nroff ----- o Two new command line options `-w' and `-W' are accepted and passed to groff to enable and disable warning messages, respectively. Preconv ------- o This is a new preprocessor to convert various input encodings to something groff understands (this is, ASCII and \[uXXXX] entities, with `XXXX' a hexadecimal number with 4 to 6 digits, representing a Unicode input code). Normally, preconv should be invoked with options `-k' and `-K' of groff. See the preconv man page for details. Pic --- o int(x) now really behaves as documented: It truncates the non-integer part of x, this is, it rounds towards zero and not towards the next integer less than or equal to x. o Pic now supports up to 32 macro arguments (and up to 16 on EBCDIC platforms). o Heinz-Jürgen Örtel contributed code for two new keywords, `xslanted' and `yslanted', which can change the shape of boxes into arbitrary parallelograms. Tbl --- o Latest versions of DWB tbl introduced an `x' column specifier for a single column expanded to the line width. GNU tbl has now been extended to support even multiple `x' specifiers within a table. o To avoid collision with the new `x' specifier, a block formatting macro must now be selected with specifier letter `m'. Eqn --- o Eric S. Raymond has added a new device type to eqn, MathML. When -TMathML is enabled, eqn now emits MathML formula markup rather than groff commands. The new groff -Txhtml device uses this. Chem ---- o The preprocessor `chem' was added. `chem' is a roff language to generate chemical structure diagrams. It generates `pic' output. Grops ----- o The PS font definition files have been regenerated with newer AFM versions from Adobe's 35 core fonts as present in most Level 2 PS printers. The changes are minor (most notably, the addition of the `Euro' glyph and an extended set of kerning values). For backwards compatibility, the old set of font definition files is still available; for details please read the man page of grops. Grotty ------ o \D'p...' is now supported if the polygon consists entirely of horizontal and vertical lines. Grohtml ------- o XHTML support has been added. o New command line option `-V' (to be used in XHTML mode) to produce an XHTML validator button. o New command line option `-y' to produce a right-justified groff signature at the end of the document (in combination with option `-V'). Gxditview --------- o Support for keyboard navigation has been improved. o Similar to other X11 applications, there are now two resource files, `GXditview' and `GXditview-color'. Groffer ------- o `groffer' version 1.* exists now in a shell and a Perl version. Afmtodit -------- o New option `-c' to output more font information as comments. o New option `-k' to suppress output of kerning data. o New option `-f NAME' to set the internal name of the groff font. Macro Packages -------------- o Joachim Walsdorff contributed the `hdtbl' package for the generation of tables, using a syntax very similar to the HTML table model. For example, a table with two cells and two rows looks like this: .TBL cols=2 . TR .TD 1*1 .TD 1*2 . TR .TD 2*1 .TD 2*2 .ETB Here the same table using a more expanded syntax: .TBL cols=2 . TR . TD 1*1 . TD 1*2 . TR . TD 2*1 . TD 2*2 .ETB Tables can be nested; `hdtbl' works without a preprocessor so that the full capability of groff's macro engine is available. This package currently works with `-Tps' only. o -mandoc now supports multiple man pages (in either man or mdoc format). o Fabrice Ménard contributed locales support. In particular, it is now possible to get French localization of the main macro packages (-ms, -mm, -me, and -mom, but not -man and -mdoc which are localized differently) by appending `-mfr' to the list of macro packages. Example: groff -ms -mfr foo > foo.ps Note that latin-9 input encoding is used for French (to support the `oe' ligature). o Swedish macro localization (with `-msv') has been added. o German macro localization (with `-mde' and `-mden' for traditional and new orthography, respectively) has been added. o Czech macro localization (with `-mcs') has been added. Note that latin-2 input encoding is used for Czech. o A new macro `Dx' has been added to the mdoc package which identifies the DragonFly OS. o If mdoc is used to print multiple man pages (together with the -rcR=0 command line option), each man page now starts a new page. o -mtrace has been considerably improved, now showing number and string register assignments, among other things. See the groff_trace man page for details. o The PSPIC macro now works with all devices (producing a hollow rectangle on devices which don't support inclusion of PS images) and is loaded in troffrc at start-up. o A new auxiliary macro package `62bit' has been added which provides some macros for adding, multiplying, and dividing signed 62bit integers (mainly to handle normal groff number operations without risking overflow errors). o For -ms, Eric S. Raymond contributed support for ancient Bell Labs localisms `.SC', `.UC', `.P1', and `.P2'. The latter three are enabled only after .SC is called. o A new string, `SN-STYLE', has been added to the ms macros, controlling the formatting of section numbers in headings defined by `.NH'. o The new macro package `ptx' provides a template definition for the `.xx' macro as needed by GNU ptx (for creating permuted indices). VERSION 1.19.2 ============== Troff ----- o Analogously to the .ft and \f pair, two new requests `gcolor' and `fcolor' (which pair with \m and \M, respectively) have been added to set the glyph and background colours. o A new read-only, string-valued register `.sty' returns the name of the current style. o Two new conditional operators `F <name>' and `S <name>' have been added. `F' is true if a font <name> exists. `S' is true if a style <name> has been registered. o Cyrillic characters have been added to the `utf8' and `html' output devices. Pic --- o The `by' argument in a `for' loop can now be negative if it is additive. For the multiplicative case, it must be greater than zero. Eqn --- o The following keywords aren't new but haven't been documented previously: undef NAME (to undefine a macro) copy "FILE" (a synonym for `include') space n (to modify the vertical spacing before and after an equation) o The following macros aren't new but haven't been documented previously: Alpha, ..., Omega (the same as `ALPHA', ..., `OMEGA') ldots (three dots on the base line) dollar (a dollar glyph) o The following keywords have been extended. Again, this isn't new but hasn't been documented previously: col n { ... } lcol n { ... } rcol n { ... } ccol n { ... } pile n { ... } lpile n { ... } rpile n { ... } cpile n { ... } (set vertical spacing between rows to N) Grohtml ------- o This device driver has been raised to beta stage; its set of tags should be stable now. o New command line option `-s' to set the base point size. o New command line option `-S' to set the split level while generating multiple files. Grotty ------ o Experimental support for zero-width and double-width characters. Gxditview --------- o On platforms which have the X Window System this program is now built and installed automatically. Xtotroff -------- o This program to create font definition files for xditview isn't new but hasn't been installed previously. Groffer ------- o A security problem (reported as CAN-2004-0969) has been fixed. Gdiffmk ------- o A new script contributed by Mike Bianchi. It compares two groff, nroff, or troff documents and creates an output with added margin characters (using `.mc') to indicate the differences. Pdfroff ------- o A new wrapper script contributed by Keith Marshall to easily create PDF documents with groff. Macro packages -------------- o ms.tmac . Support for fractional point sizes: A value for the `PS', `VS', `FPS', and `VPS' register larger than or equal to 1000 is always divided by 1000. For example, `.nr PS 10250' sets the document's font size to 10.25 points. . The `Ds' and `De' macros provided in ms since groff version 1.19 have been removed; the equivalent `DS' and `DE' macros should be used instead. X11 documents which actually use `Ds' and `De' always load a specific macro file from the X11 distribution (`macros.t') which provides proper definitions for the two macros. . The following registers have been added for improving layout control: PORPHANS Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which must be kept together, before any automatic page break. HORPHANS Sets number of lines of following paragraph which must be kept with a heading, defined by `NH' or `SH', before any automatic page break. GROWPS Sets the first level of heading (set with `NH') which keeps the same point size as body text. PSINCR Sets the point size increment for each level of heading (set with `NH'), below the threshold level set by `GROWPS'; e.g., if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p, then `.NH 1' produces 14pt headings, `.NH 2' produces 12pt, and all other levels remain at 10pt (because \n[PS] = 10). . The `SH' macro now accepts a numeric argument, to make heading size match that of `NH' with same argument value when the `GROWPS'/`PSINCR' feature is enabled. Please refer to the documentation of the ms package for other, minor improvements. o me.tmac The section type set with the `++' request is available in the `_M' register. This isn't new but hasn't been documented before. o www.tmac The `HR' macro no longer causes an empty line for non-HTML devices. A new macro `HEAD' has been added to directly add data to the <head>...</head> block. New macros `OLS' and `OLE' to start and end an ordered list. New macros `DLS' and `DLE' to start and end a definition list. Pdfmark ------- o A new macro package contributed by Keith Marshall which implements PDF marks. This is in alpha stage currently. Miscellaneous ------------- o Two new keywords to the DESC file have been added which are needed for grohtml: `image_generator' and `unscaled_charwidths'. The former gives the name of the program which creates PNG images, and the latter makes troff always use unscaled character widths. VERSION 1.19.1 ============== Groff ----- o The argument of the command line option `-I' is now also passed to troff and grops, specifying a directory to search for files on the command line, files named in `so' and `psbb' requests, and files named in \X'ps: file' and \X'ps: import' escapes. o If option `-V' is used more than once, the commands are both printed on standard error and run. Troff ----- o Two new read-only, string-valued registers `.m' and `.M' return the name of the current drawing and background color, respectively. o New read-only register `.U' which is set to 1 if in safer mode and set to 0 if in unsafe mode. o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added. Example use: groff -Tdvi -mlatin5 my_file > my_file.dvi Note that some output devices don't support all glyphs of this encoding. o If the `return' request is called with an argument, it exits twice, namely the current macro and the macro one level higher. This is used to define a wrapper macro for `return' in trace.tmac. o For completeness, two new requests have been added: `dei1' and `ami1'. They are equivalent to `dei' and `ami', respectively, but the macros are executed with compatibility mode off (similar to `de1' and `am1'). o New command line option `-I' to specify a directory for files (both those on the command line and those named in `psbb' requests). This is also handled by the groff wrapper program. o Since version 1.19 you can say `.vs 0'. Older versions emit a warning and convert this to `.vs \n[.V]'. This hasn't been documented properly. Note that `.vs 0' isn't saved in a diversion since it doesn't result in vertical motion. Pic --- o Dashed and dotted ellipses have been implemented. Tbl --- o New specifier `x' to make tbl call a user-defined macro on a table cell. Patch by Heinz-Jürgen Oertel <hj.oertel@surfeu.de>. Grap2graph ---------- o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It converts a grap diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. [Note that the grap program itself isn't part of the groff package; see the file MORE.STUFF how to obtain grap.] Grohtml ------- o New option `-j' to emit output split into multiple files. Grops ----- o New command line option `-I' to specify a directory to search for files on the command line and files named in \X'ps: import' and \X'ps: file' escapes. This is also handled by the groff wrapper program. o The default value for the `broken' keyword in the DESC file is now 0. Grolj4 ------ o A new man page `lj4_font(5)' documents how fonts are accessed with grolj4. o The built-in fonts for LJ4 and newer PCL 5 devices have been completely revised, mainly to access as much glyphs as possible. The provided metric files should be compatible with recent PCL 5 printers also. Additionally, font description files have been added for the Arial and Times New Roman family, the MS symbol, and Wingdings fonts. Afmtodit -------- o New option `-x' to prevent use of built-in Adobe Glyph List. Hpftodit -------- o Completely revised to handle HP TrueType metric files also. See the hpftodit manual page for more details. Groffer ------- o This version is a rewrite of groffer in many parts, but it is kept in the old single script style. New options: --text, --mode text, --tty-viewer, --X, --mode X, --X-viewer, --html, --mode html, --html-view, --apropos-data, --apropos-devel, --apropos-progs. New documentation file: README_SH. Enhancement of the configuration files and the `apropos' handling. Macro Packages -------------- o www.tmac: New macro `JOBNAME' to split output into multiple files. o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY section. VERSION 1.19 ============ Troff ----- o Input encoding files for latin-9 (a.k.a. latin-0 and ISO 8859-15) and latin-2 (ISO 8859-2) have been added. Example use: groff -Tdvi -mlatin9 my_file > my_file.dvi You still need proper fonts with the necessary glyphs. Out of the box, the groff package supports latin-9 only for -Tps, -Tdvi, and -Tutf8, and latin-2 only for -Tdvi and -Tutf8. o Composite glyphs are now supported. To do this, a subset of the Adobe Glyph List (AGL) Algorithm as described in http://partners.adobe.com/public/developer/opentype/index_glyph.html is used to construct glyph names based on Unicode character codes. The existing groff glyph names are frozen; no glyph names which can't be constructed algorithmically will be added in the future. The \[...] escape sequence has been extended to specify multiple glyph components. Example: \[A ho] this accesses a glyph with the name `u0041_0328'. Some groff glyphs which are useful as composites map to `wrong' Unicode code points. For example, `ho' maps to U+02DB which is a spacing ogonek, whereas a non-spacing ogonek U+0328 is needed for composite glyphs. The new request .composite from to changes the mapping while a composite glyph name is constructed. To make \[A ho] yield the expected result, .composite ho u0328 is needed. [The new file `composite.tmac' loaded at start-up already contains proper calls to `.composite'.] Please refer to the info pages of groff and to the groff_char man page for more details. o A new request `fschar' has been added to define font-specific fallback characters. They are searched after the list of fonts declared with the `fspecial' request but before the list of fonts declared with `special'. o Fallback characters defined with `fschar' can be removed with the new `rfschar' request. o A new request `schar' has been added to define global fallback characters. They are searched after the list of fonts declared with the `special' request but before the already mounted special fonts. o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the current point horizontally. Despite of being silly, this change has been reverted for backwards compatibility. Consequently, the intermediate output command `Df' also moves the position horizontally again. \D'f ...' is deprecated since it depends on the horizontal resolution of the output device (given with the `hor' parameter in the DESC file). Use the new \D'Fg ...' escape instead. o For orthogonality, new \D subcommands to change the fill color are available: \D'Fr ...' (rgb) \D'Fc ...' (cmy) \D'Fg ...' (gray) \D'Fk ...' (cmyk) \D'Fd' (default color) The arguments are the same as with the `defcolor' request. The current position is *not* changed. o The values set with \H and \S are now available in number registers \n[.height] and \n[.slant], respectively. o The `.pe' number register isn't new but hasn't been documented before. It is set to 1 during a page ejection caused by the `bp' request. o The new glyph symbol `tno' is a textual variant of `no'. o The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL. (Well, it is not really new since it has been previously supported by grolj4.) The mapping for both the dvi and lj4 symbol font has been changed accordingly so that Greek small letter epsilon, `*e', has the same glyph shape as with other devices. Grops ----- o The font `freeeuro.pfa' has been added to provide various default glyph shapes for `eu' and `Eu'. o It is now possible to access all glyphs in a Type 1 font, not only 256 (provided the font file created by afmtodit has proper entries). grops constructs additional encoding vectors on the fly if necessary. o The paper size is now emitted via the %%DocumentMedia and PageSize mechanisms so that it is no longer required to tell `gv' or `ps2pdf' about the paper size. The `broken' flag value 16 omits this feature (the used PostScript command `setpagedevice' is a LanguageLevel 2 extension) -- if you intend to further process grops output to get an encapsulated PS (EPS) file you must also use this option. Patch by Egil Kvaleberg <egil@kvaleberg.no>. o Non-slanted PostScript metrics have been changed again; they no longer contain negative left italic correction values. This assures correct spacing with eqn. Grodvi ------ o The font cmtex10 has been added as the special font `SC' to the DVI fonts. It is used as a font-specific special font for CW and CWI. o New options -l and -p to set landscape orientation and the paper size. grodvi now emits a `papersize' special which is understood by DVI drivers like dvips. Consequently, the DESC file should contain a `papersize' keyword. o The glyph shapes for \[*f] and \[*e] have been exchanged with \[+f] and \[+e], respectively, to be in sync with all other devices. o Glyphs \[HE] and \[DI] have been replaced with \[u2662] and \[u2661], respectively, since the former two glyphs have a black (filled) shape which grodvi doesn't provide by default (it never has actually). Grolj4 ------ o The glyphs \[*e] and \[+e] have been exchanged to be in sync with all other devices. o The glyph \[~=] is now called \[|=]. Similar to other devices, \[~=] is now another name for glyph \[~~]. Grotty ------ o New option `-r'. It is similar to the -i option except it tells grotty to use the `reverse video' attribute to render italic fonts. Pic --- o New command `figname' to set the name of a picture's output box in TeX mode. Refer ----- o The environment variable `REFER' to override the name of the default database isn't new but hasn't been documented before. Soelim ------ o New option `-r' to avoid emission of `.lf' lines. o New option `-t' to emit TeX comment lines (giving current file and the line number) instead of `.lf' lines. Afmtodit -------- o Unencoded glyphs in an AFM file are output also (since grops can now emit multiple encoding vectors for a single font). o New option `-m' to prevent negative left italic correction values. o The mapping and encoding file together with file `DESC' are now searched in the default font directory also. Please refer to the man page of afmtodit for more details. Macro Packages -------------- o Larry Kollar <kollar@alltel.net> and others made the man macros more customizable. . New command line options -rFT, -rIN, and -rSN to set the vertical location of the footer line, the body text indentation, and the sub-subheading indentation. . New command line option -rHY (similar to the ms macros) to control hyphenation. . New macros `.PT' and `.BT' to print the header and footer strings. They can be replaced with a customized version in `man.local'. . The string `HF' now holds the typeface to print headings and subheadings. . Similar to the ms macros, the LT register now defaults to LL if not explicitly specified on the command line. o troff's start-up file `troffrc' now includes `papersize.tmac' to set the paper size with the command line option `-dpaper=<size>'. Possible values for `<size>' are the same as the predefined `papersize' values in the DESC file (only lowercase; see the groff_font man page) except a7-d7. An appended `l' (ell) character denotes landscape orientation. Examples: `a4', `c3l', `letterl'. Most output drivers need additional command line switches `-p' and `-l' to override the default paper length and orientation as set in the driver specific DESC file. For example, use the following for PS output on A4 paper in landscape orientation: groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps VERSION 1.18.1 ============== Troff ----- o The non-slanted PostScript font definition files have been regenerated to include left and right italic correction values. Applying those to a glyph (this is, prepending the glyph with `\,' and appending `\/' to the glyph) sets the glyph width to the real value given by the horizontal bounding box values. Without those escapes, the advance width for the particular glyph is used (which can differ considerably). Most users will neither need this feature nor notice a difference in existing documents (provided \, and \/ is used as advertised, namely for italic fonts only); its main goal is to improve image generation with grohtml. This is an experimental change, and feedback is welcome. Tbl --- o Added global option `nospaces' to ignore leading and trailing spaces in data items. Grolbp ------ o The option -w (--linewidth) has been added (similar to other device drivers) to set the default line width. Grn --- o Support for b-spline and Bezier curves has been added. Groffer ------- o New option `--shell' to select the shell under which groffer shall run. Macro Packages -------------- o The string `Am' (producing an ampersand) has been added to mdoc for compatibility with NetBSD. o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit) instead. o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal and vertical movements; please refer to contrib/mom/NEWS for more details. o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers. Miscellaneous ------------- o The `papersize' keyword in the DESC file now accepts multiple arguments. It is scanned from left to the right, and the first valid argument is used. This makes it possible to provide a fallback paper size. Example: papersize /etc/papersize a4 o A local font directory has been prepended to the default font path; it defaults to /usr/local/share/groff/site-font. Similar to the normal font searching process, files must be placed into a devXXX subdirectory, e.g. /usr/local/share/groff/site-font/devps/FOO for a PostScript font definition file FOO. VERSION 1.18 ============ *************************************************************************** * * * PLEASE READ THE CHANGES BELOW REGARDING GROTTY, GROFF'S TTY FRONTEND. * * * *************************************************************************** Troff ----- o Color support has been added to troff and pic (and to the device drivers grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will follow). A new function `defcolor' defines colors; the escape sequence `\m' sets the drawing color, the escape sequence `\M' specifies the background color for closed objects created with \D'...' commands. `\m[]' and `\M[]' switch back to the previous color. `\m' and `\M' correspond to the new troff output command sets starting with `m' and `DF'. The device-specific default color is called `default' and can't be redefined. Use the `color' request to toggle the usage of colors (default is on); the read-only register `.color' is 0 if colors are not active, and non-zero otherwise. The old `Df' output command is mapped onto `DFg'; all color output commands don't change the current font position (consequently, `Df' doesn't either). Outputting color can be disabled in troff and groff with the option -c (it is always disabled in compatibility mode). See the section on grotty for the GROFF_NO_SGR environment variable also. For defining color components as fractions between 0 and 1, a new scaling indicator `f' has been introduced: 1f = 65536u. For testing whether a color is defined (with .if and .ie), a new conditional operator `m' is available. More details can be found in the groff_diff.7 manual page and in groff.texinfo. o Similar to \m and \M, \f[] switches back to the previous font. \fP (and \f[P]) is still valid for backwards compatibility. o The new escape \F is the same as `.fam'; \F[] switches back to previous family -- \F[P] selects family `P'. o Two new glyph symbols are available: `eu' is the official Euro symbol; `Eu' is a font-specific glyph variant. o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of `+-', `di', and `mu', respectively. o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has got the troff glyph name `mc'. o -Tutf8 is now available on EBCDIC hosts. o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...]. Example: .ds xxx This is a \\$1 test. \*[xxx nice] o It is now possible to have whitespace between the first and second dot (or the name of the ending macro) to end a macro definition. Example: .de ! .. . .de foo . nop Hello, I'm `foo'. . nop I will now define `bar'. . de bar ! . nop Hello, I'm `bar'. . ! .. o `.fn' is a new string-valued register which returns the (internal) real font name; styles and families are properly concatenated. o Three new read/write registers `seconds', `minutes', and `hours' contain the current time, set at start-up of troff. Use the `af' request to control their output format. o The new request `fchar' can be used to provide fallback characters. It has the same syntax as the `char' request; the only difference is that a character defined with `.char' hides the glyph with the same name in the current font, whereas a character defined with `.fchar' is checked only if the particular glyph isn't found in the current font. This test happens before checking special fonts. o In analogy to the `tmc' request, `.writec' is the same as `.write' but doesn't emit a final newline. o The new request `itc' is a variant of `.it' for which a line interrupted with \c counts as one input line. o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but with compatibility mode disabled during expansion of strings defined by them. o The syntax of the `substring' request has been changed: The first character in a string now has index 0, the last character has index -1. Note that this is an incompatible change. o To emit strings directly to the intermediate output, a new `output' request has been added; it is similar to `\!' used at the top level. o `.hpf' has been extended. It can now handle most TeX hyphenation pattern files without modification. To do that, the commands \patterns, \hyphenation, and \endinput are recognized. Please refer to groff_diff.7 for more information. o `hpfcode' is a new request to provide an input encoding mapping for the `hpf' request. o The new request `hpfa' appends hyphenation patterns (`hpf' replaces already existing patterns). o A new request `ami' (append macro indirect) has been added. The first and second parameter of `ami' are taken from string registers rather than directly; this very special request is needed to make `trace.tmac' independent from the escape character (which might even be disabled). o The new request `sizes' is similar to the `sizes' command in DESC files. It expects the same syntax; the data must be on a single line, and the final `0' can be omitted. o `trin' (translate input) is a new request which is similar to `tr' with the exception that the `asciify' request uses the character code (if any) before the character translation. Example: .trin ax .di xxx a .br .di .xxx .trin aa .asciify xxx .xxx The result is `x a'. Using `tr', the result would be `x x'. o The request `pvs' isn't new, but hasn't been documented before. It adds vertical space after a line has been output. This makes it an alternative to the `ls' request to produce double-spaced documents. The read-only register `.pvs' holds the current amount of the post-vertical line space. o For compatibility with plan 9's troff, multiple `pi' requests are supported: .pi foo .pi bar is now equivalent to .pi foo | bar o A new escape sequence `\O' is available to disable and enable glyph output. Please see groff_diff.7 and groff.texinfo for more details. o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X; they are ignored now. Additionally `\ ' and `\~' are converted to single space characters. o The default tab distance in nroff mode is now 0.8i to be compatible with UNIX troff. o Using the latin-1 input character 0xAD (soft hyphen) for the `shc' request was a bad idea. Instead, it is now translated to `\%', and the default hyphenation character is again \[hy]. Note that the glyph \[shc] is not useful for typographic purposes; it only exists to have glyph names for all latin-1 characters. Macro Packages -------------- o Peter Schaffter <df191@ncf.ca> has contributed a new major macro package called `mom', mainly for non-scientific writers, which takes care of many typographic issues. It comes with a complete reference (in HTML format) and some examples. `mom' has been designed to format documents for PostScript output only. o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to the man macros for compatibility with older BSD releases. o Both the man and mdoc macro packages now use the LL and LT registers for setting the line and title length, respectively (similar to those registers in the ms macro package). If not set on the command line or in a macro file loaded before the macro package itself, they default to 78n in nroff mode and 6.5i in troff mode. o The `-xwidth' specifier in the mdoc macro package has been removed. Its functionality is now integrated directly into `-width'. Similarly, `-column' has been extended to provide this functionality also. o A new macro `Ex' has been added to the mdoc macro package to document an exit status. o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is now automatically loaded for -Tdvi), using a dvips special to load the EPS file. o The trace.tmac package now traces calls to `am' also. Additionally, it works in compatibility mode. o `troff.1' has been split. Differences to UNIX troff are now documented in the new man page `groff_diff.7'. o `groff_mwww.7' has been renamed to `groff_www.7'. The file mwww.tmac has been removed. o `groff_ms.7' has been completely rewritten. It now contains a complete reference to the ms macros. o `groff_trace.7' documents the trace macro package. o Changes in www.tmac: Note that HTML support is still in alpha change, so it is rather likely that both macro names and macro syntax will change. Some of the macros mentioned below aren't really new but haven't been documented properly before. The following macros have been renamed: MAILTO -> MTO IMAGE -> IMG LINE -> HR For consistency, the macros `URL', `FTL', and `MTO' now all have the address as the first parameter followed by the description. By default, grohtml generates links to all section headings at the top of the document. Use the new `LK' macro to specify a different place. For specifying the background color and a background image, use the new macros `BCL' and `BGIMG', respectively. The macro `NHR' has been added; it suppresses the generation of top and bottom rules which grohtml emits by default. The new macro `HX' determines the cut-off point for automatic link generation to headings. The image position parameter names in `IMG' have been changed to `-L', `-R', and `-C'. New macro `PIMG' for inclusion of a PNG image (it automatically converts it into an EPS file if not -Thtml is used). New macro `MPIMG' for putting a PNG image into the left or right margin (it automatically converts it into an EPS file if not -Thtml is used). New macros `HnS', `HnE' to start and end a header line block. New macro `DC' to produce dropcap characters. New macro `HTL' to generate an HTML title line only but no H1 heading. New macros `ULS' and `ULE' to start and end an unordered list. The new macro `LI' inserts a list item. Groff ----- o The new command line option `-c' disables color output (which is always disabled in compatibility mode). Nroff ----- o Two new command line options `-c' and `-C'; the former passes `-c' to grotty (switching to the old output scheme); the latter passes `-C' to groff (enabling compatibility mode). Pic --- o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or `outlined'), and `shaded' are available. `outline' sets the color of the outline, `shaded' the fill color, and `color' sets both. Example: circle shaded "green" outline "black" ; Filled arrows always use the outline color for filling. Color support for TeX output is not implemented yet. Pic2graph --------- o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It converts a PIC diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. Eqn2graph --------- o A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It converts an EQN diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. Groffer ------- o A new script contributed by Bernd Warken <bwarken@mayn.de>. It displays groff files and man pages on X and tty, taking care of most parameters automatically. Grog ---- o Documents using the mom macro package are recognized. Grops ----- o Color support has been added. o A new option `-p' is available to select the output paper size. It has the same syntax as the new `papersize' keyword in the DESC file. Grodvi ------ o By default, font sizes are now available in the range 5-10000pt, similar to PS fonts. If you want the old behaviour (i.e., font sizes at discrete values only), insert the following at the start of your document: .if '\*[.T]'dvi' \ . sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \ 1728 1800 2000 2074 2200 2400 2488 2800 3600 o A new font file HBI (using cmssbxo10; this is slanted sans serif bold extended) has been added. o Two font families are now available: `T' and `H'. o EC and TC fonts have been integrated. Use `-mec' (calling the file ec.tmac) to switch to them. Those fonts give a much better coverage of the symbols defined by groff than the CM fonts. Note that ec.tmac must be called before any language-specific files; it doesn't take care of hcode values. o Color support has been added. For drawing commands, colors are translated to gray values currently. Grotty ------ o Color support has been added, using the SGR (ISO 6429, sometimes called ANSI color) escape sequences. o SGR escape sequences are now used by default for underlining and bold printing also, no longer using the backspace character trick. To revert to the old behaviour, use the `-c' switch. Note that you have to use the `-R' option of `less' to make SGR escapes display correctly. On the other hand, terminal programs and consoles like `xterm' which support SGR sequences natively can directly display the output of grotty. Consequently, the options `-b', `-B', `-u', and `-U' work only in combination with `-c' and are ignored silently otherwise. For the `man' program, it may be necessary to add the `-R' option of `less' to the $PAGER environment variable (or $MANPAGER, depending on the used `man' program); alternatively, you can use `man's `-P' option (or adapt its configuration file accordingly). See man(1) for more details. o If the environment variable GROFF_NO_SGR is set, SGR output is disabled, reverting to the old behaviour. o A new special \X'tty: sgr n' has been added; if n is non-zero or missing, enable SGR output (the default). o If the new option `-i' is used (only in SGR mode), grotty sends escape sequences to set the italic font attribute instead of the underline attribute for italic fonts. Note that many terminals don't have support for this (including xterm). Grohtml ------- o Color support for glyphs has been added. o New option `-h' to select the style of headings in HTML output. o New option `-b' to set the background colour to white. o New options `-a' and `-g' to control the number of bits for anti-aliasing used for text and graphics, respectively. Default value is 4; 0 means no anti-aliasing. o groff character/glyph entities now map onto HTML 4 character entities. Grolbp ------ o Valid paper sizes are now specified as with the new `papersize' keyword in the DESC file. Specifically, the old custom paper type format `custAAAxBBB' is no longer supported. Miscellaneous ------------- o A new manual page `ditroff.7' is available. o The groff texinfo manual is installed now, together with a bunch of examples. o A new keyword `papersize' has been added to the DESC file format. Its argument is either . a predefined paper format (e.g. `A4' or `letter') . a file name pointing to a file which must contain a paper size specification in its first line (e.g. `/etc/papersize') . a custom paper size definition like `35c,4i' See groff_font(5) for more details. This keyword only affects the physical dimensions of the output medium; grops, grolj4, and grolbp use it currently. troff completely ignores it. VERSION 1.17.2 ============== This is major bug-fixing release which should replace 1.17.1. Troff ----- o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter gives the horizontal image location (left, centered, or right), and the optional 3rd and 4th parameter the image dimensions. VERSION 1.17.1 ============== This is mainly a bug-fixing release. Troff ----- o Two new requests `de1' and `am1' which are similar to `de' and `am' but with compatibility mode disabled during expansion of macros defined by them. o Added request `brp'. This is the same as `\p'. o Similar to other versions of troff, the `ns' request now works in all diversions, not only in the top-level one. o New read-only number register `.ns'. Returns 1 if in no-space mode, 0 otherwise. Nroff ----- o Options -p (pic) and -t (tbl) added. o The environment variable GROFF_BIN_PATH is now checked before PATH for finding groff. Grohtml ------- o New option `-D dir' to specify a directory in which all images are placed. o New option `-I stem' to specify an image name stame. If not given, `grohtml-XXX' is used (`XXX' is the process ID). VERSION 1.17 ============ Groff ----- o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'. The old behaviour has been changed to overcome problems with platforms which have an 8+3 file name limit, and platforms which have other versions of troff installed also. Additionally, all macro files have been renamed using the latter scheme to avoid 8+3 name clashes. o The new environment variable GROFF_BIN_PATH is checked for programs groff is calling (preprocessors, troff, and output devices) before PATH. If not set, it defaults to the directory where the groff binary is located. Previously, it was PATH only. The nroff script only uses GROFF_BIN_PATH to find the groff binary but passes both the GROFF_BIN_PATH and PATH environment variables to groff. Troff ----- o The mdoc package has been completely rewritten, using the full power of GNU troff to remove limitations of Unix troff (which is no longer supported). Most important changes are: . No argument limit . Almost all macros are parsed and callable (if it makes sense) . `.Lb': prints library names . `.Nm <punctuation>' now works as expected; `.Nm "" <punctuation>' has been withdrawn . Updated `.St' command . `.Fx': prints FreeBSD . `.Ox': prints OpenBSD . `.Bsx': prints BSD/OS . `.Brq', `.Bro', `.Brc': brace enclosure macros . `.Bd -centered': center lines . `.Bl -xwidth <string>': interpret <string> and use the resulting width . Support for double-sided printing (-rD1 command line switch) . Support for 11pt and 12pt document sizes (-rS11, -rS12 command line switches) `groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely documents the mdoc package. Great care has been taken to assure backwards compatibility. If you encounter any abnormal results, please report them to bug-groff@gnu.org. o A new command line option for the `man' macros (similar to the `mdoc' package) has been implemented: `-rcR=1' (now the default in nroff mode) produces one single, very long page instead of multiple pages. `-rcR=0' deactivates it. o The `return' request has been added to return immediately from a macro. o A new request `nop' (no operation) has been added which is similar to `if 1'. For example, .if t \{\ Hallo! .\} can now be written as .if t \{\ . nop Hallo! .\} o `box' and `boxa' are two new requests which behave similarly to `di' and `da' but don't include a partially filled line (which is restored after ending the diversion). o The `asciify' request has been extended to `unformat' space characters and some other escape sequences also. `\ ' is no longer unformatted as a space but remains an unpaddable, unbreakable space character. o The new `unformat' request is similar to `asciify' but only handles space characters and tabs specially if the diversion is reread, retaining font information. This makes it possible to reformat diversions; for example the following .ll 3i . a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. . .box box1 .ev 1 .nf \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P] .br .ev .box . c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. . .unformat box1 .box1 gives a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. b01 b02 b03 b04 b05 b06 b07 b08 b09 b10. Without the `unformat' request, space characters are converted to word space nodes which are no longer stretchable, and the result would be a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. b01 b02 b03 b04 b05 b06 b07 b08 b09 b10. o The new request `linetabs' controls the `line-tabs' mode. In line-tabs mode, tab distances are computed relative to the (current) output line. Otherwise they are taken relative to the input line. For example, the following .ds x a\t\c .ds y b\t\c .ds z c .ta 1i 3i \*x \*y \*z yields a b c In line-tabs mode, the same code gives a b c The new read-only number register `.linetabs' returns 1 if in line-tabs mode, and 0 otherwise. o Two new requests `tm1' and `tmc' have been added to improve writing messages to the terminal. `tm1' is similar to `tm' but allows leading whitespace. `tmc' is similar to `tm1' but doesn't emit a final newline. o For compatibility with sqtroff, the request `output' has been added. The behaviour is similar to `\!' at the top-level, that is, it directly inserts its argument into the intermediate output format. The syntax is similar to .tm1, allowing leading whitespace. o The new `spreadwarn' request makes troff warn if spaces in an output line are widened by a given limit or more. o Use `warnscale' to change the scaling indicator troff uses for warning messages. o A new request `dei' (define indirect) has been added. The first and second parameter of `dei' are taken from string registers rather than directly; this very special request is needed to make `trace.tmac' independent from the escape character (which might even be disabled). o It is now possible to save and restore the escape character with two new requests `ecs' and `ecr'. o The new escape sequence \B'...' is an analogon to `\A': If the string within the delimiters is a valid numeric expression, return character `1', and `0' otherwise. o The new escape sequence `\:' inserts a zero-width break point. This is similar to `\%' but without a soft hyphen character. o The `tr' request can now map characters onto `\~'. o Calling the `fam' request without an argument switches back to the previous font family. o The new read-only register `.int' is set to a positive value if the last output line is interrupted (i.e., if the input line contains `\c'). o The `writem' request is not new, but hasn't been documented before. This is similar to `write' but instead of a string the contents of a given macro or string is written to a stream. o The read/write number register `hp' to get/set the current horizontal position relative to the input line isn't new but hasn't been documented properly before. o `\X' and `\Y' are now transparent for end-of-sentence recognition. o The `cu' request in nroff mode now works as documented (i.e., it underlines spaces also). Grog ---- o The grog script now works in non-compatibility mode also (which is the default). As usual, use the `-C' option to activate compatibility mode. Grops ----- o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has been added to select a different prologue file. o The effect of the former `-mpsnew' option to access more Type 1 characters is now the default and no longer available. To get the old behaviour (i.e., emulation of some glyphs by composition) use `-mpsold'. Miscellaneous ------------- o For security reasons the following changes have been done: . The tmac.safer file has been replaced with a built-in solution; .open, .opena, .pso, .sy, and .pi are completely disabled in safer mode (which is the default); to enable these requests the `-U' command line flag must be used. . Files specified with the .mso request or given with the `-m' command line option, and hyphenation patterns loaded with `.hpf' are no longer searched in the current directory by default (besides the usual tmac path). Instead, the home directory is used. To add the current directory, either use the `-U' or `-M' command line option or set the GROFF_TMAC_PATH environment variable to an appropriate value. . troffrc, troffrc-end, and eqnrc are neither searched in the current nor in the home directory (even if -U is given). Use -M or GROFF_TMAC_PATH to change that. . Similarly, the current directory is no longer part of the font path. Use the `-F' command line option or the GROFF_FONT_PATH environment variable if you really need the current directory. o groff now installs its data files into /usr/local/share/groff/<version> by default, following the GNU standard. Additionally, a local tmac directory (by default /usr/local/share/groff/site-tmac) is scanned before the standard tmac directory. Wrapper files for system-specific macro packages (if necessary) are put into /usr/local/lib/groff/site-tmac; this directory is searched before the local tmac directory. o All programs now have option `-v' to show the version number; they exit immediately afterwards, following the GNU standards. Additionally, `--version' and `--help' have been added, doing the obvious actions. VERSION 1.16.1 ============== Bug fixes only; no user-visible changes. VERSION 1.16 ============ Groff ----- The anachronism of calling the man macro package with `-man' has been fixed; now you can say `-m man' also. The same is true for `ms', `me', `markup', `mandoc', and `mdoc'. A new switch `-g' for calling `grn' is available. A new switch `-G' for calling `grap' is available. EBCDIC support for tty devices has been added. On such hosts, IBM code page 1047 is available with -Tcp1047 instead of -Tascii and -Tlatin1 (and, for the moment, -Tutf8). Note that non-tty devices are not yet supported (but installed). Troff ----- A new command line option to the `man' macros is available: `-rSxx' (with `xx' either 10, 11, or 12) to set the base document font size to `xx' points. Additionally, `.SH' now produces larger headings than `.SS'. To solve a problem with the .PSPIC macro which needs the `-U' switch of troff to access an external program (psbb), a new request .psbb is now available to get the bounding box of a PostScript image file. The values (in PostScript units) are returned in the new read-only number registers `llx', `lly', `urx', and `ury'. Consequently, .PSPIC has been adapted to use the new request, and the psbb program has been removed. A new predefined writable number register, `year', has been added. It contains the current year. A new read-only register, `.Y', has been added. It contains the revision number of the groff package. `\fP' now behaves as expected in situations like the following where the font `foo' is undefined: .B bold text normal text \f[foo]bar\fP normal text Previously, the text after \fP appeared as bold. The `substring' request is not new, but hasn't been documented before. The predefined `.T' string register (which holds the current output device) is not new, but hasn't been documented before. A new request `length' computes the length of a string and returns it in a number register. The macro files `tmac.a4' (for specifying A4 paper format) and `tmac.trace' (a debugging aid) are now installed also. A new resource file, `troffrc-end', is now available. It is invoked after all user-specified macros. Currently used by the html device to include tmac.html; thus no need for users to specify -mhtml anymore. The soft hyphen character now has a glyph name: `shc'. The latin-1 character 173 (PS name `periodcentered') has got the troff glyph name `pc' and is no longer intermixed with the symbol character `md' (PS name `mathdot'). ASCII character 34 (PS name `quotedbl') has got the troff glyph name `dq' (which is an alias to character `"'). ASCII character 39 (PS name `quoteright') has got the troff glyph name `cq' (which is an alias to character "'"). Some additions to the font description files have been implemented for better support of HTML output: The new format of lines in the `charset' subsection of font description files is name metrics type code [entity_name] [-- comment] Currently, only the font description files in devhtml use the optional entity_name string to define glyph entities in HTML. Everything after the entity_name field is ignored; in case this field isn't used, two hyphen characters are now necessary to start a comment. Two new requests are available in DESC files (currently used only with grohtml): use_charnames_in_special This command indicates that troff should encode named characters inside special commands. pass_filenames requests that troff tells the driver the source file name being processed. This is achieved by another tcommand: `F filename'. Grotty ------ Bruno Haible <haible@clisp.cons.org> contributed support for UTF8 output. Grohtml ------- Added .LINE macro to tmac.arkup. The obsolete `.LINK' macro has been removed. .URL, .FTP, and .MAILTO macros now accept an optional third argument which is immediately appended to the second argument (to be used with punctuation, for example). Grodvi ------ The font size 11pt has been changed to 10.95pt (as used in LaTeX 2e). A new font file CWI (using cmitt10; this is typewriter italic) has been added. Grolbp ------ A new driver for Canon CAPSL printers (LBP-4 and LBP-8 series laser printers). This code has been contributed by Francisco Andres Verdu <pandres@dragonet.es>. Grn --- A new preprocessor to process gremlin pictures. It is based on the original Berkeley implementation of grn, written by David Slattengren and Barry Roitblat, and has been adapted to groff by Daniel Senderowicz <daniel@synchrods.com> and Werner Lemberg <wl@gnu.org>. Pic --- Added the `srand' command to set the seed for a new sequence of pseudo-random numbers to be returned by `rand'. Gxditview --------- Simplified installation: The Imakefile is now configured (by groff's configure script). Documentation ------------- Three new man pages are available: groff_tmac.5 (documenting how troff macros are accessed and where they are found), groff.7 (a short reference of the GNU roff language), and roff.7 (a general survey on GNU troff). Miscellaneous ------------- A partial port to win32 (for use with Microsoft Visual C++ 6.0) is now part of the distribution. It has been contributed by Blake McBride <blake@florida-software.com>. More information about programs, macros, documentation, etc., which is related to groff has been collected in the file `MORE.STUFF'. VERSION 1.13, 1.14, 1.15 ======================== Bug fixes only; no user-visible changes. VERSION 1.12 ============ Finally, there are new maintainers for groff. Mailing lists and a CVS repository are available also. See the file README for details. Not all reported bugs could be fixed, so please send mails again if something is still not working. Most of the installation problems should have vanished now (most notably the $(tmac_wrap) bug). There is now a man page called groff_man.7 which documents the basics of the -man macros. It has been originally written by Susan G. Kleinmann <sgk@debian.org>. A (still incomplete) groff reference manual in texinfo format originally contributed by Trent A. Fisher <trent@gnurd.portland.or.us>. me.man and msafer.man have been renamed to groff_me.man resp. groff_msafer.man for consistency. Default strings for macros in doc-common resp. tmac.an no longer contain the word `UNIX'. groff should now be Y2k safe (fixes contributed by Paul Eggert <eggert@twinsun.com>). Following the GNU standards, groff now uses the prefix `/usr/local/' as the default instead of replacing an existent groff binary. groff, troff, nroff, and pic now support the -U flag to activate unsafe behaviour (without -msafer); the -S flag for using the -msafer macros is now the default. Grohtml ------- This is a new output device for producing HTML output contributed by Gaius Mulley <gaius@glam.ac.uk>. It is still very alpha but has been included into the distribution so that a lot of people have a chance to test it. Bug reports are highly welcome. Grolj4 ------ Duplex printing support has been contributed by Jeffrey Copeland <jeff@opennt.com>. Soelim ------ Added -I option for defining include paths (patch contributed by Peter Miller <peterm@jna.com.au>). Gxditview --------- Fallback resources added (patch contributed by Larry Jones <larry.jones@sdrc.com>). Will now support 8 gray levels. mm -- New version 1.32 (contributed by Joergen Haegg <jh@axis.com>). VERSION 1.11 ============ Complete documentation for pic is now in the file doc/pic.ms. It was contributed by Eric S. Raymond, <esr@thyrsus.com>, who is emphatically *not* volunteering to take over groff as he is way overworked with half a dozen other projects. VERSION 1.10 ============ The directory where data files are installed has been changed from /usr/local/lib/groff to /usr/local/share/groff to comply with the latest GNU coding standards. By default groff programs with Unix equivalents are installed with a "g" prefix unless there is an existing (non-groff) troff installation. A new approach is used to make system macro packages available to groff. Instead of simply including /usr/lib/tmac in the list of directories searched by groff, the installation process creates for each system macro package a wrapper macro package in the groff macro directory that references the system macro package. The groff macro packages are now installed with a leading "g" prefix if there is a system version of the same macro package, and otherwise without the "g" prefix, with the exception that the groff version of -me which is always installed as -me. There is a new device, lj4, for the HP LaserJet 4 (and PCL5 compatibles). Groff ----- groff has a -S option that prevents the use of unsafe features in pic and troff. This uses a new -S option of pic and the -msafer macros for troff. Troff ----- The `blm' request specifies a macro to be invoked when a blank line is encountered. Pic --- A -S (safer) option disables the sh command. Grops ----- The -m option enables manual feed. VERSION 1.09 ============ \(rn now produces a character that has the traditional metrics, and form corners with \(ul and \(br. This means that it does not align properly with \(sr. Instead there's a new character \[radicalex] which aligns with \(sr; this is used by eqn for doing square roots. Troff ----- The `pso' request allows you to read from the standard output of a command. Grops ----- The PSPIC macro has options to allow the horizontal alignment of the graphic to be specified. VERSION 1.08 ============ Troff ----- The escape sequence \V[xxx] interpolates the value of the environment variable xxx. Tbl --- The decimalpoint option can be used to specify the character to be recognized as the decimal point character in place of the default period. VERSION 1.07 ============ Groff ----- The environment variable GROFF_COMMAND_PREFIX can be used to control whether groff looks for `gtroff' or `troff' (similarily for the preprocessors.) Troff ----- Multilingual hyphenation is supported by new `hpf' and `hla' requests, and by a `\n[.hla]' number register. The -H option has been removed. Files of hyphenation patterns can have comments. When a font cannot be found, troff gives a warning (of type `font', enabled by default) instead of an error. There's a new request `trnt' that's like `tr' except that it doesn't apply to text transparently throughput into a diversion with \!. Tbl --- There is a `nokeep' option which tells tbl not to use diversions to try to keep the table on one page. Eqn --- Setting the parameter `nroff' to a non-zero value causes `ndefine' to behave like `define' and `tdefine' to be ignored. This is done by eqnrc when the current device is ascii or latin1. There's a `neqn' script that just does `eqn -Tascii'. Grotty ------ grotty uses whatever page length was specified using the `pl' request rather than using the paperlength command in the DESC file. The paperwidth command in the DESC file is also ignored. VERSION 1.06 ============ The programs in groff that have Unix counterparts can now be installed without a leading `g' prefix. See the `g' variable in the Makefile. The g?nroff script simulates the nroff command using groff. New special characters \(+h, \(+f, \(+p, \(Fn, \(Bq, \(bq, \(aq, \(lz, \(an. See groff_char(7). ^L is now a valid input character. Groff ----- The Xps pseudo-device has disappeared. Instead there is a new -X option that tells groff to use gxditview instead of the usual postprocessor. (So instead of -TXps, use -XTps or just -X if your default device is ps.) The postprocessor to be used for a particular device is now specified by a `postpro' command in the DESC file rather than being compiled into groff. Similarly the command to be used for printing (with the -l option) is now specified by a `print' command in the DESC file. The groff command no longer specifies eqnchar as an input file for eqn. Instead eqn automatically loads a file `eqnrc'. The groff command no longer passes the -D option to eqn. Instead eqnrc sets the draw_lines parameter. The groff command no longer tells troff to load a device-specific macro file. This is handled instead by the `troffrc' file, which is always loaded by troff. The shell script version of groff has been removed. Troff ----- The `rchar' request removes a character definition established with `char'. Compatibility mode is disabled and the escape character is set to `\' while a character definition is being processed. The `\#' escape sequence is like `\"' except that the terminating newline is ignored. The `shc' request tells troff which character to insert (instead of the default \(hy) when a word is hyphenated at a line break. A font name of 0 (zero) in the DESC file causes no font to be mounted on the corresponding font position. This is useful for arranging that special fonts are mounted on positions on which users are not likely explicitly to mount fonts. All groff devices now avoid initially mounting fonts on positions 5-9. The `do' request allows a single request or macro to be interpreted with compatibility mode disabled. troff automatically loads a file `troffrc' before any other input file. This can be prevented with the -R option. This file is responsible for loading the device-specific macros. Pic --- The -x option has been removed and a -n option has been added. By default, pic now assumes that the postprocessor supports groff extensions. The -n option tells pic to generate output that works with ditroff drivers. The -z option now applies only to TeX mode. The -p option has been removed. Instead if the -n option is not specified, pic generates output that uses \X'ps: ...' if the \n(0p register is non-zero and tmac.ps sets this register to 1. In places where you could 1st or 5th you can now say `i'th or `i+1'th (the quotes are required). Eqn --- Eqn now automatically reads a file `eqnrc' from the macro directory. This performs the same role that the eqnchar files used to. This can be prevented by the -R option. Setting the draw_lines parameter to a non-zero value causes lines to be drawn using \D rather than \l. The -D option is now obsolete. `uparrow', `downarrow' and `updownarrow' can be used with `left' and `right'. The amount of extra space added before and after lines containing equations can be controlled using the `body_height' and `body_depth' parameters. Grops ----- Font description files have been regenerated from newer AFM files. You can get access to the additional characters present in the text fonts in newer PostScript printers by using -mpsnew. The default value of the -b option is specified by a `broken' command in the DESC file. With the -g option, grops generates PostScript code that guesses the page height. This allows documents to be printed on both letter (8.5x11) and A4 paper without change. Grodvi ------ ISO Latin-1 characters are available with -Tdvi. Format groff_char(7) with groff -Tdvi for more information. Grotty ------ The -mtty-char macros contain additional character definitions for use with grotty. Macros ------ In previous releases the groff -me macros treated the $r and $R number registers in a way that was incompatible with the BSD -me macros. The reason for this was that the approach used by the BSD -me macros does not work with low resolution devices such as -TX75 and -TX100. However, this caused problems with existing -me documents. In this release, the vertical spacing is controlled by the $v and $V registers which have the same meaning as $r and $R in earlier groff releases. In addition, if the $r or $R register is set to a value that would be correct for for the BSD -me macros and a low resolution device is not being used, then an appropriate value for the $v or $V register is derived from the $r or $R register. The groff -me macros work with -C and (I think) with Unix troff. For backward compatibility with BSD -me, the \*{ and \*} strings are also available as \*[ and \*]. Of course, \*[ is only usable with -C. The \*T string has been deleted. Use \*(Tm instead. Xditview -------- The `n', Space and Return keys are bound to the Next Page action. The `p', BackSpace and Delete keys are bound to the Previous Page action. The `q' key is bound to the Quit action. The `r' key is bound to a rerasterize action that reruns groff, and redisplays the current page. VERSION 1.05 ============ Pic --- There is a alternative assignment operator `:=' which interacts differently with blocks. There is a new command `command', which allows the values of variables to be passed through to troff or TeX. The `print' command now accepts multiple arguments. String comparison expressions (using `==' or `!=') are allowed in more contexts. Grotty ------ Horizontal and vertical lines drawn with \D'l ...' are rendered using -, | and + characters. This is intended to give reasonable results with boxed tables. It won't work well with pic. Macros ------ The -mdoc macros have been upgraded to the version in the second Berkeley networking release. This version is not completely compatible with earlier versions; the old version is still available as -mdoc.old. The grog script has been enhanced so that it can usually determine whether a document requires the old or new versions. With -TX75, -TX100 and -TXps, the PSPIC macro produces a box around where the picture would appear with -Tps. VERSION 1.04 ============ An implementation of the -mm macros is included. The directory in which temporary files are created can be controlled by setting the GROFF_TMPDIR or TMPDIR environment variables. Pic --- Some MS-DOS support (see pic/make-dos-dist). Grops ----- There are two new \X commands (\X'ps: invis' and \X'ps: endinvis') which make it possible to have substitute characters that are displayed when previewing with -TXps but ignored when printing with grops. Xditview -------- Support for scalable fonts. VERSION 1.03 ============ No changes other than bug fixes. VERSION 1.02 ============ There is an implementation of refer and associated programs. groff -R preprocesses with grefer; no mechanism is provided for passing arguments to grefer because most grefer options have equivalent commands which can be included in the file. grog also supports refer. There is an alternative perl implementation of the grog script. The code field in lines in the charset section of font description files is now allowed to contain an arbitrary integer (previously it was required to lie between 0 and 255). Currently grops and grodvi use only the low order 8 bits of the value. Grodvi uses the complete value; however, this is unlikely to be useful with traditional TeX tools (.tfm files only allow 8 bit character codes.) Left and right double quotes can be obtained with \(lq and \(rq respectively. There is a new program called pfbtops which translates PostScript fonts in pfb format to ASCII. A slightly modified version of the Berkeley tmac.doc is included. Troff ----- In long escape names the closing ] is now required to be at the same input level as the opening [. The \A'S' escape sequence returns 1 or 0 according as S is or is not suitable for use as a name. \~ produces an unbreakable space that can be stretched when the line is adjusted. The `mso' request is like the `so' request except that it searches for the file in the same directories in which tmac.X is searched for when the -mX option is given. The escape sequence `\R' is similar to the `nr' request. Eqn --- A new `special' primitive allows you to add new types of unary constructs by writing a troff macro. Pic --- The implementation no longer uses gperf. Grops ----- The compile-time -DBROKEN_SPOOLER option has been replaced by a BROKEN_SPOOLER_FLAGS option. This allows more precise control over how grops should workaround broken spoolers and previewers. There is a new -b option that can change this at run-time. Grops now generates PostScript that complies with version 3.0 of the Document Structuring Convention. The resource management component of grops (the part that deals with imported documents and downloadable fonts) has been rewritten and now supports version 3.0 of the Document Structuring Conventions. The %%DocumentFonts comment is no longer supported; you must use the %%Document{Needed,Supplied}{Fonts,Resources} comments instead (or as well.) tmac.psatk contains some macros that support the mechanism used by the Andrew Toolkit for including PostScript graphics in troff documents. Xditview -------- Parts of xditview have been rewritten so that it can be used with the output of gtroff -Tps. groff -TXps runs gtroff -Tps with gxditview. There is a new menu entry `Print' which brings up a dialog box for specifying a command with which the file being previewed should be printed. Xditview now uses imake. VERSION 1.01 ============ The groff command now understands the gtroff `-a' and `-i' options. With the `m' and `n' scale indicators, the scale factor is rounded horizontally before being applied. This makes (almost) no difference for devices with `hor' equal to 1, but it makes groff with -Tascii or -Tlatin1 behave more like nroff in its treatment of these scale indicators. Accordingly tmac.tty now calls the `nroff' request so that the `n' condition is true. The device-specific macros (tmac.ps, tmac.dvi, tmac.tty and tmac.X) have been made to work at least somewhat with -C. In particular the special characters defined by these macros now work with -C. groff -Tdvi -p now passes pic the -x flag; this enables filling of arrowheads and boxes, provided that your dvi driver supports the latest version of the tpic specials. Eqn --- There is a new `-N' option that tells eqn not to allow newlines in delimiters. This allows eqn to recover better from missing closing delimiters. The groff command passes on a `-N' option to eqn. Grops ----- You can now use psfig with grops. See the file ps/psfig.diff. I do not recommend using psfig for new documents. The command \X'ps: file F' is similar to \X'ps: exec ...' except that the PostScript code is read from the file F instead of being contained within the \X command. This was added to support psfig. Grodvi ------ There are font files HB and HI corresponding to cmsssbx10 and cmssi10. Macros ------ The groff -me macros now work with the -C option. As a result, they may also work with Unix nroff/troff. In -me, the $r and $R number registers now contain the line spacing as a percentage of the pointsize expressed in units (normally about 120). The previous definition was useless with low resolution devices such as X75 and X100. VERSION 1.00 ============ A -ms-like macro-package is now included. The name for the Icelandic lowercase eth character has been changed from \(-d to \(Sd. Troff ----- There is a new request `nroff', which makes the `n' built-in condition true and the `t' built-in condition false; also a new request `troff' which undoes the effect of the `nroff' request. This is intended only for backward compatibility: it is usually better to test \n(.H or \n(.V or to use the `c' built-in condition. The \R escape sequence has been deleted. Use \E instead. There are `break' and `continue' requests for use with the `while' request. There is a request `hym' that can ensure that when the current adjustment mode is not `b' a line is not hyphenated if it is no more than a given amount short, and a request `hys' that can ensure that when the current adjustment mode is `b' a line is not hyphenated if it can be justified by adding no more than a given amount of extra space to each word space. There is a request `rj' similar to `ce' that right justifies lines. A warning of type `space' is given when a call is made to an undefined request or macro with a name longer than two characters, and the first two characters of the name make a name that is defined. This is intended to find places where a space has been omitted been a request or macro and its argument. This type of warning is enabled by default. Pic --- A comma is permitted between the arguments to the `reset' command. For use with TeX, there is a new `-c' option that makes gpic treat lines beginning with `.' in a way that is more compatible with tpic (but ugly). Eqn --- It is no longer necessary to add `space 0' at the beginning of complicated equations inside pictures. `prime' is now treated as an ordinary character, as in Unix eqn. The previous behaviour of `prime' as an operator can now be obtained using `opprime'. Xditview -------- There are two new devices X75-12 and X100-12 which are the same as X75 and X100 except that they are optimized for documents that use mostly 12 point text. VERSION 0.6 =========== The installation process has been refined to make it easy for you to share groff with someone who has the same type of machine as you but does not have a C++ compiler. See the end of the INSTALL file for details. There is a man page for the tfmtodit program which explains how to use your own fonts with groff -Tdvi. There is a man page for afmtodit which explains how to use your own PostScript fonts with groff -Tps. The \N escape sequence is now fully supported. It can now be used to access any character in a font by its output code, even if it doesn't have a groff name. This is made possible by a convention in the font files that a character name of `---' refers to an unnamed character. The drivers now all support the `N' command required for this. The font description files have been updated to include unnamed characters. The `x' command in font description files has been removed: instead any unknown commands are automatically made available to the drivers. If you constructed your own font files with an earlier version of tfmtodit or afmtodit, you must construct them again using the current version. Characters between 0200 and 0237 octal are no longer valid input characters. Note that these are not used in ISO 8859. A command called `grog' has been added, similar to the `doctype' command described in Kernighan and Pike. Groff ----- The groff command has some new options: -V prints the pipeline instead of executing it; -P passes an argument to the postprocessor, -L passes an argument to the spooler. There is a C++ implementation of the groff command. This handles some things slightly better than the shell script. In particular, it can correctly handle arguments containing characters that have a special meaning to the shell; it can give an error message when child processes other than the last in the pipeline terminate abnormally; its exit status can take account of the exit statuses of all its child processes; it is a little more efficient; when geqn is used, it searches for the eqnchar file in the same way that font metric files are searched for, rather than expecting to find it in one particular directory. Gtroff ------ There is font translation feature: For example, you can tell gtroff to use font `HR' whenever font `H' is requested with the line .ftr H HR This would be useful for a document that uses `H' to refer to Helvetica. There are some new number registers: `.kern' contains the current kern mode, `.lg' the current ligature mode, `.x' the major version number, `.y' the minor version number, `.ce' the number of lines to be centered in the current environment, `.trunc' the amount of vertical space truncated by the most recently sprung vertical position trap, `.ne' the amount of vertical space needed in the last `ne' request that caused a vertical position trap to be sprung. The `cf' request now behaves sensibly in a diversion. If used in a diversion, it now arranges for the file to be copied to the output when the diversion is reread. There is a new request `trf' (transparent file) similar to `cf', but more like `\!'. There is a new escape sequence `\Y[xxx]', roughly equivalent to `\X'\*[xxx]'', except that the contents of string or macro xxx are not interpreted, and xxx may contain newlines. This requires an output format extension; the drivers have been modified to understand this. Grops has also been modified to cope with newlines in the arguments to \X commands; grops has a new \X command mdef, which is like def except that it has a first argument giving the number of definitions. There is a new warning category `escape' which warns about unknown escape sequences. The `fp' request now takes an optional third argument giving the external name of the font. The `\_' character is now automatically translated to `\(ul' as in troff. The environment variable `GROFF_HYPHEN' gives the name of the file containing the hyphenation patterns. There is a `\C'xxx'' escape sequence equivalent to `\[xxx]'. Characters ", ', ), ], *, \(dg are now initially transparent for the purposes of end of sentence recognition. There is an anti-recursion feature in the `char' request, so you can say `.char \(bu \s+2\(bu\s-2'. The limit on the number of font positions has been removed. Accordingly `\n[.fp]' never returns 0. The restriction on the number of numbered environments has been removed. There is a new escape sequence `\E' that makes it possible to guarantee that an escape sequence won't get interpreted in copy-mode. The `\R' escape sequence is accordingly now deprecated. Gpic ---- Arguments of the form `X anything X' (in the `copy thru', `sh', `for', `if' and `define' constructs) can now be of the form `{ anything }'. If the `linethick' variable is negative (as it now is initially), lines are drawn with a thickness proportional to the current point size. The `rand' function now takes no arguments and returns a number between 0 and 1. The old syntax is still supported. `^' can be used in expressions to indicate exponentiation. In the `for' construct the argument to the by clause can be prefixed by `*' to indicate that the increment is multiplicative. A bare expression may be used as an attribute. If the current direction is `dir', then an attribute `expr' is equivalent to `dir expr' There is a `sprintf' construct that allows numbers to be formatted and used wherever a quoted string can be used. The height of a text object without an explicit height attribute is the number of text strings associated with the object times the value of the `textht' variable. The maximum height and width of a picture is controlled by the `maxpswid' and `maxpsht' variables. Gtbl ---- Gtbl can now handle gracefully the situation where the `ce' request has been applied to a table. Geqn ---- The `ifdef' primitive has been generalized. A tilde accent can be put underneath a box using `utilde'. This defined using a general `uaccent' primitive. Grops ----- There is a new PostScript font downloading scheme which handles font downloading for imported illustrations. Previously, the name of the file containing the font was given in the `x download' line in the groff font metric file. Now, there is a `download' file which says for each PostScript font name which file contains that font. Grops can also now handle inter-font dependencies, where one downloadable font depends on some other (possibly downloadable) font. The `T' font has been removed. The characters it used to provide are now provided by `char' definitions in tmac.ps. TSymbol.ps has also been removed, and the tweaks it provided are now provided by `char' definitions.
