95 real_output_file() and pclose() in ~real_output_file().
97 2000-02-27 Werner LEMBERG <wl@gnu.org>
99 Adding a new driver, grolbp, for Canon CAPSL printers (LBP-4 and
100 LBP-8 series laser printers). This code has been contributed by
101 Francisco Andres Verdu <pandres@dragonet.es>.
103 * src/devices/grolbp/*: The grolbp output device.
104 * font/devlpb/*: The font description files.

137 2000-02-24 Werner LEMBERG <wl@gnu.org>
139 * src/preproc/grn/main.cc: Introduce BASE_THICKNESS, defining
140 line thicknesses to be integer multiples of this value.
142 * src/preproc/grn/grn.man: Commenting out the -s option -- the
143 corresponding code doesn't work (yet).
145 * doc/groff.texinfo: Further checking/updating. Adding more index
148 2000-02-23 Werner LEMBERG <wl@gnu.org>

214 if parameters are absent is exactly the same as before.
216 2000-02-11 Abramo Bagnara <abramo@alsa-project.org>

238 2000-02-06 Werner LEMBERG <wl@gnu.org>
240 I've considerably modified the directory structure of the
241 distribution to get a more vertical layout. For example, the number
242 of top level directories has been reduced from 42 to 6.
244 As a consequence, many changes, especially to the makefiles, were
247 * The makefile variables `top_builddir' and `top_srcdir' have been
248 introduced. Virtually all relative paths have been replaced with
249 absolute ones using these two variables.
251 * Dependencies (in the files `Makefile.dep') are no longer part of
252 the distribution. Instead, they are created during a `make install'
253 in the build directory.
255 * aclocal.m4 (GROFF_SRCDIR, GROFF_BUILDDIR): Two new functions to
256 make `top_srcdir' and `top_builddir' absolute.
260 * Man pages no depend on the files `VERSION' and `REVISION'.
262 * The added shell script `mkinstalldirs' will replace `mkdir' in
265 * VERSION: Version number increased to 1.16.
267 2000-02-04 Werner LEMBERG <wl@gnu.org>
269 * grops/psrm.cc (read_one_of): Fixed pointer incrementation.
271 * Makefile.in: Removed $(tmac_m) since it is no longer needed
272 (after an update of the mm stuff).
274 * troff/Makefile.sub (majorminor.cc): Fix dependencies.
276 2000-02-03 Werner LEMBERG <wl@gnu.org>
278 The .psbb request will now also accept Mac PS images (i.e. using LF
279 as the EOL character).
281 * troff/input.cc (ps_get_line): New function, taken from psrm.cc
282 (with slight modifications).
283 * troff/input.cc (do_ps_file): Use it.
285 * test-groff: Add grohtml and grolj4 output devices to PATH.
287 2000-01-30 Werner LEMBERG <wl@gnu.org>
289 * NEWS, MORE.STUFF: Updated.
291 2000-01-30 Cary D. Renzema <caryr@dollar.mxim.com>

297 * pic/pic.cc, pic/pic.tab.h: Regenerated (with yacc).
299 2000-01-30 Werner LEMBERG <wl@gnu.org>
301 Add a new request `.psbb'. This does exactly what the external
302 program psbb did. It scans a PostScript image file for a
303 %%BoundingBox comment and extracts the bounding box values (in
304 PostScript units) which are then stored in the four new (read-only)
305 number registers `llx', `lly', `urx', and `ury'.
307 This will allow the usage of the .PSPIC macro without worrying
308 about unsafe behaviour of groff, i.e., it will work without the
309 `-U' switch of groff.
311 * troff/input.cc: Implement it.
312 * tmac/tmac.pspic: Use it.
313 * troff/troff.man, grops/grops.man, NEWS: Document it.
314 * psbb/*, Makefile.in: Remove it since it is no longer needed.
316 This is bloody C code simply adapted from psbb.c! Any improvements
319 2000-01-29 Werner LEMBERG <wl@gnu.org>
321 * man/groff_font.man: Minor clarifications.
325 2000-01-28 Werner LEMBERG <wl@gnu.org>

339 * tmac/tmac.arkup, tmac/groff_markup.man: Replace \fC...\fR with

344 2000-01-27 Gaius Mulley <gaius@glam.ac.uk>
346 Completed the pass_filenames implementation in troff.

352 2000-01-26 Werner LEMBERG <wl@gnu.org>
354 * troff/env.cc (set_font): Fix the behaviour of \fP. The previous
355 font will now be updated even if an invalid font is selected.
357 2000-01-24 Werner LEMBERG <wl@gnu.org>
359 * doc/homepage.ms: Updated for new tmac.arkup.
361 * tmac/tmac.html: Disable line breaks after hyphen-like characters.
363 * tmac/tmac.arkup: Cleanup.
365 Added `\&' to .HTML macro to `leave vertical mode', so to say.
367 Removed obsolete .LINK macro completely.
369 The macros .URL, .FTP, and .MAILTO now accept a third argument which
370 will be immediately appended to the second argument (to be used with
371 punctuation, for example).
373 Disabled .CDFTP macro temporarily for security reasons.
375 * tmac/groff_markup.man: Complete revision for latest changes in
376 tmac.arkup -- note that it does not yet format correctly with
379 2000-01-23 Bruno Haible <haible@clisp.cons.org>
381 * nroff/nroff.sh: Accept -Tutf8 option and pass it through.
382 * devutf8/R.proto: Add mappings for wp, lh, rh.

385 2000-01-23 Werner LEMBERG <wl@gnu.org>

389 2000-01-21 Gaius Mulley <gaius@glam.ac.uk>

408 * tmac/Makefile.sub: tmac.a4 and tmac.trace have been removed by
409 mistake from the list of files to be installed.
411 2000-01-18 Werner LEMBERG <wl@gnu.org>
413 * README: Added info how to apply patches.
415 2000-01-15 Jan Echternach <echter@informatik.uni-rostock.de>

6519 SUPPRESS_BOTTOM_REG back to 0. In T#, do nothing if
6520 SUPPRESS_BOTTOM_REG is non-zero. In T#, always mark the current

6571 (font::load_desc): Check the values of font::hor and font::vert.
6573 * lib/lib.h: Added definition of INT_DIGITS. Fix it so that it can
6574 be included in a C compilation.
6575 (iftoa): Use INT_DIGITS. Include lib.h.
6577 (as_string): Likewise.

6605 issuing the need request the table still will not fit. Also
6606 remove the diversion after bringing it back.
6608 * tbl/table.c (table::init_output): Define a new macro
6609 REPEATED_MARK_MACRO, like mk but if in a diversion also
6610 transparently outputs itself.

6612 is necessary because .TH might not call .T#.
6613 (table::do_top): Likewise TOP_REG.
6614 (table::define_bottom_macro): If TOP_REG is no longer valid, use
6615 #T - DOUBLE_LINE_SEP rather than #T. This is necessary because the

6633 optional 5th argument to .TH which specifies the manual name and
6634 appears in the center of the header. Understand the X, P and D
6637 Wed Jul 18 10:23:31 1990 James Clark (jjc at yquem)

6665 * troff/input.c (init_input_requests): Bind ex request to
6666 exit_request rather than exit_groff.
6668 * troff/input.c (exit_groff): Call tok.next() before
6669 process_input_stack().
6671 Mon Jul 16 09:47:23 1990 James Clark (jjc at yquem)
6673 * troff/env.c: ifdef widow control support on WIDOW_CONTROL.
6674 * troff/env.h: ditto.
6675 * troff/input.c: ditto.
6677 * troff/env.c (environment::is_empty): Test pending_lines.
6679 * troff/env.c (environment::have_pending_lines): Removed.

6691 environment after END_TRAP token seen, but only if there aren't
6692 any more traps still unfinished.
6693 * troff/token.h: Remove TOKEN_FLUSH_PENDING_LINES.
6695 Sun Jul 15 10:50:08 1990 James Clark (jjc at yquem)
6697 * troff/env.c: Rename the `retain_size' member of class
6698 pending_output_line to `no_fill'.
6700 * troff/env.c (title): When the line is output, make the
6701 retain_size argument !fill.
6703 * troff/node.h: Add `hyphenated' member to struct breakpoint.
