74 if parameters are absent is exactly the same as before.
76 2000-02-11 Abramo Bagnara <abramo@alsa-project.org>

98 2000-02-06 Werner LEMBERG <wl@gnu.org>
100 I've considerably modified the directory structure of the
101 distribution to get a more vertical layout. For example, the number
102 of top level directories has been reduced from 42 to 6.
104 As a consequence, many changes, especially to the makefiles, were
107 * The makefile variables `top_builddir' and `top_srcdir' have been
108 introduced. Virtually all relative paths have been replaced with
109 absolute ones using these two variables.
111 * Dependencies (in the files `Makefile.dep') are no longer part of
112 the distribution. Instead, they are created during a `make install'
113 in the build directory.
115 * aclocal.m4 (GROFF_SRCDIR, GROFF_BUILDDIR): Two new functions to
116 make `top_srcdir' and `top_builddir' absolute.
120 * Man pages no depend on the files `VERSION' and `REVISION'.
122 * The added shell script `mkinstalldirs' will replace `mkdir' in
125 * VERSION: Version number increased to 1.16.
127 2000-02-04 Werner LEMBERG <wl@gnu.org>
129 * grops/psrm.cc (read_one_of): Fixed pointer incrementation.
131 * Makefile.in: Removed $(tmac_m) since it is no longer needed
132 (after an update of the mm stuff).
134 * troff/Makefile.sub (majorminor.cc): Fix dependencies.
136 2000-02-03 Werner LEMBERG <wl@gnu.org>
138 The .psbb request will now also accept Mac PS images (i.e. using LF
139 as the EOL character).
141 * troff/input.cc (ps_get_line): New function, taken from psrm.cc
142 (with slight modifications).
143 * troff/input.cc (do_ps_file): Use it.

159 2000-01-30 Werner LEMBERG <wl@gnu.org>
161 Add a new request `.psbb'. This does exactly what the external
162 program psbb did. It scans a PostScript image file for a
163 %%BoundingBox comment and extracts the bounding box values (in
164 PostScript units) which are then stored in the four new (read-only)
165 number registers `llx', `lly', `urx', and `ury'.
167 This will allow the usage of the .PSPIC macro without worrying
168 about unsafe behaviour of groff, i.e., it will work without the
169 `-U' switch of groff.
171 * troff/input.cc: Implement it.
172 * tmac/tmac.pspic: Use it.
173 * troff/troff.man, grops/grops.man, NEWS: Document it.
174 * psbb/*, Makefile.in: Remove it since it is no longer needed.
176 This is bloody C code simply adapted from psbb.c! Any improvements

212 2000-01-26 Werner LEMBERG <wl@gnu.org>
214 * troff/env.cc (set_font): Fix the behaviour of \fP. The previous
215 font will now be updated even if an invalid font is selected.
217 2000-01-24 Werner LEMBERG <wl@gnu.org>
219 * doc/homepage.ms: Updated for new tmac.arkup.
221 * tmac/tmac.html: Disable line breaks after hyphen-like characters.
223 * tmac/tmac.arkup: Cleanup.
225 Added `\&' to .HTML macro to `leave vertical mode', so to say.
227 Removed obsolete .LINK macro completely.
229 The macros .URL, .FTP, and .MAILTO now accept a third argument which
230 will be immediately appended to the second argument (to be used with
231 punctuation, for example).
233 Disabled .CDFTP macro temporarily for security reasons.
235 * tmac/groff_markup.man: Complete revision for latest changes in
236 tmac.arkup -- note that it does not yet format correctly with
239 2000-01-23 Bruno Haible <haible@clisp.cons.org>
241 * nroff/nroff.sh: Accept -Tutf8 option and pass it through.

269 mistake from the list of files to be installed.
271 2000-01-18 Werner LEMBERG <wl@gnu.org>
273 * README: Added info how to apply patches.

6440 * troff/input.c (input_input_requests): Likewise.
6441 * ps/ps.c (make_encoding_name): Likewise.
6442 (ps_printer::set_style): Likewise.
6443 (ps_output::put_number): Use 1 + INT_DIGITS + 1 instead of 12.
6445 * tty/devascii/R.proto: Map fm onto '.
6446 * tty/devlatin1/R.proto: Likewise.
6448 Sat Jul 21 12:45:07 1990 James Clark (jjc at yquem)
6450 * tbl/table.c: Use ' instead of DELIMITER_CHAR in places where the
6451 argument to \w is at a different input level.
6453 * tbl/table.c (table::init_output): Define a new macro
6454 REPEATED_VPT_MACRO, like vpt but if in a diversion also
6455 transparently outputs itself.
6456 (table::define_bottom_macro): Use REPEATED_VPT_MACRO instead of
6458 (table::do_row): Likewise.
6460 * tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with
6461 TRANSPARENT_STRING_NAME.
6463 * tbl/table.c (table::init_output): In the table release macro
6464 print an error message and don't produce any output if after
6465 issuing the need request the table still will not fit. Also
6466 remove the diversion after bringing it back.
6468 * tbl/table.c (table::init_output): Define a new macro
6469 REPEATED_MARK_MACRO, like mk but if in a diversion also
6470 transparently outputs itself.
6471 (table::do_row): Mark row_top_reg using REPEATED_MARK_MACRO. This
6472 is necessary because .TH might not call .T#.
6473 (table::do_top): Likewise TOP_REG.
6474 (table::define_bottom_macro): If TOP_REG is no longer valid, use
6475 #T - DOUBLE_LINE_SEP rather than #T. This is necessary because the
6476 table header might contain just the two top rules.

6488 * troff/div.c: New number register .pn returns the number of the
6489 next page as set by the pn request.
6491 * macros/tmac.an: Redid headers and footers. Number each manual
6492 entry starting from 1 unless \nC is > 0, like Sun. Added an
6493 optional 5th argument to .TH which specifies the manual name and
6494 appears in the center of the header. Understand the X, P and D
6497 Wed Jul 18 10:23:31 1990 James Clark (jjc at yquem)
6499 * troff/env.c (init_env_requests): New number register `.lt' to

6511 * troff/input.c (input_stack::clear): New function.
6512 * troff/input.c (exit_request): Use input_stack::clear.
6514 * troff/token.h: Removed TOKEN_NO_PRINT_CHAR.
6515 * troff/input.c (token::process): Removed case TOKEN_NO_PRINT_CHAR.

6519 * troff/env.c (title): Split off the reading of the parts of the
6520 title into read_title_parts.
6521 * troff/input.c (read_title_parts): New function. Check the
6522 input_level when testing whether a token matches the delimiter.
6524 * troff/input.c (exit_request): New function.
6525 * troff/input.c (init_input_requests): Bind ex request to
6526 exit_request rather than exit_groff.
6528 * troff/input.c (exit_groff): Call tok.next() before
6529 process_input_stack().
6531 Mon Jul 16 09:47:23 1990 James Clark (jjc at yquem)
6533 * troff/env.c: ifdef widow control support on WIDOW_CONTROL.
6534 * troff/env.h: ditto.
6535 * troff/input.c: ditto.
6537 * troff/env.c (environment::is_empty): Test pending_lines.
6539 * troff/env.c (environment::have_pending_lines): Removed.
6541 * troff/input.c: Add request to flush pending lines from the

6546 * troff/input.c (exit_groff): Do process_input_stack() after
6547 do_break() but before setting exit_flag to 2.
6549 * troff/input.c: Remove FLUSH_PENDING_LINES and
6550 TOKEN_FLUSH_PENDING_LINES. Instead, flush pending lines from
6551 environment after END_TRAP token seen, but only if there aren't
6552 any more traps still unfinished.
6553 * troff/token.h: Remove TOKEN_FLUSH_PENDING_LINES.
6555 Sun Jul 15 10:50:08 1990 James Clark (jjc at yquem)
6557 * troff/env.c: Rename the `retain_size' member of class
6558 pending_output_line to `no_fill'.
6560 * troff/env.c (title): When the line is output, make the
6561 retain_size argument !fill.
6563 * troff/node.h: Add `hyphenated' member to struct breakpoint.
6564 * troff/node.c (space_node::get_breakpoints),
6565 (dbreak_node::get_breakpoints): Fill this in.
6566 * troff/env.c: Allow specification of maximum number of
6567 consecutive hyphenated lines.
6569 * troff/env.c (environment::is_empty): Add test for !current_tab.
6571 Sat Jul 14 11:23:01 1990 James Clark (jjc at yquem)
6573 * troff/env.c (environment::hyphenate_line): Don't completely give
6574 up if the word is not to be hyphenated; continue so that breaks
6575 can be made at break_char_node's.
6577 * lib/lib.h: Only define INT_MAX if it's not already defined;
6578 undef INT_MIN if it's already defined.
6580 * Makefile: Make it easy to define CFRONT_ANSI_BUG.
6582 * lib/lib.h: If CFRONT_ANSI_BUG is defined, cast INT_MIN to long.
6583 This works around a bug in AT&T C++ 2.0 used with an ANSI C
6586 * macros/tmac.an (an-header): Set no-space mode.
6588 * macros/tmac.an (TH): Start a new page if necessary.
