Bug fixes are not described. There are more details in the man and info pages. +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/asn/developer/typeforum/unicodegn.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 + + will change 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). 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 ============== @@ -8,11 +229,11 @@ Troff ----- o The non-slanted PostScript font definition files have been regenerated to - include left and right italic correction values.
