Bug fixes -are not described. There are more details in the man pages. - -VERSION 1.09 -============ - -\(rn will now produce a character that has the traditional metrics, -and will form corners with \(ul and \(br. This means that it will 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] will interpolate 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 legal 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 will cause 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 will generate 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 will -be 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, \*[ will only be 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 ...' will be 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 will produce 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 will use 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 will run 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 will be 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 will now pass pic the -x flag; this will enable 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 will pass 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 will not be 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 will not be -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' will be 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 legal 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 will now arrange 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 will be 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. |
