Fix indentation in SYNOPSIS.

Updated to include changes of latest BSD mdoc version (basically,
the only change is that `.Fn' and `.Fc' put a final semicolon after
a function declaration in the SYNOPSIS section).

* tmac/doc.tmac (doc-in-synopsis-count): Replaced with ...
(doc-in-synopsis-section): New variable. Updated all related
functions.
(doc-indent-synopsis-active): New register.
(Nd, Fn, Fo): Use it.

undesirable line break to be output.
(doc-do-func-decl, Nm, Vt, Fn, Fo): Remove extraneous calls to
`.rs'.
(Fn, Fc): Add final `;' to output.

2001-02-16 Werner LEMBERG <[email protected]>

Fixing a bug which prevented proper end-of-sentence recognition
between an `unformatted' box and the following text. As a
consequence, vertical line distances are no longer preserved in
boxes after a call to `.unformat' -- because boxes aren't
line-oriented (contrary to diversions), this doesn't make sense
anyway.

* src/roff/troff/node.cc (*node::set_unformat_flag): Add return
value.
(vertical_size_node::set_unformat_flag): New method.
* src/roff/troff/node.hh: Updated.

documentation of `asciify' and `unformat' requests.

2001-02-13 Werner LEMBERG <[email protected]>

Redesigned the `unformat' request. It is no longer connected with
`asciify' but rather uses new `reread()' methods if the `unformat'
flag is set. Additionally, the handling of space characters after
unformatting has been fixed so that they retain their width.

* src/roff/troff/node.h (width_list): New structure to store
original widths of spaces.
(node): Added `unformat' member.
Replaced `num_spaces' variable with `orig_width' list.
* src/roff/troff/node.cc (*node::asciify,
asciify_reverse_node_list): Removed `unformat_only' flag and related
code.
(word_space_node::asciify, word_space_node::word_space_node): Use
`orig_width'.
(word_space_node::~word_space_node): New destructor.
(word_space_node::copy): Updated to handle `orig_width'.
(hmotion_node::copy, unbreakable_space_node::copy): Updated.
(*node::merge_space): Update `orig_width' list if necessary.
(*node::set_unformat_flag): New methods to set the `unformat' flag.

unbreakable_space_node::reread, hmotion_node::reread): New methods
to handle nodes specially if `unformat' flag is set.
(do_asciify_macro): Renamed back to ...
(asciify_macro): This.

flag.

* MORE.STUFF: Added more info about deroff.

2001-02-08 Werner LEMBERG <[email protected]>

* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
and `add_self()' methods to avoid hyphenation. For example, the
hyphen list for `foo\0\0bar' was `foobar', causing insertion of a
soft hyphen after `foo'. Now the hyphen list is correctly
`foo<ignore><ignore>bar'.

2001-02-05 Yoshiteru Kageyama <[email protected]>

* tmac/groff_tmac.man: Fix `BIR' macro.

2001-02-04 Werner LEMBERG <[email protected]>

* src/roff/troff/input.cc (process_input_stack): Remove now obsolete
label.
(token::next): Move creation of an unbreakable_space_node to...
(token::add_to_node_list): Here.

Fix a bug which sometimes prevented hyphenation of words connected
with `\~' or `\ ' (and other escape sequences handled as
TOKEN_NODE). This also fixes a hyphenation problem with boxes
(after a call to the `unformat' request).

* src/roff/troff/env.h (environment::possibly_break_line,
environment::hyphenate_line): Introducing `start_here' parameter.
* src/roff/troff/env.cc (environment::space_newline,
environment::space): Use it.
(environment::possibly_break_line, environment::hyphenate_line):

2001-01-28 Werner LEMBERG <[email protected]>

Fixed a bug which prevented hyphenation of words which are finished
with `\)'.

* src/roff/troff/token.h (token): Add enum type
`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
* src/roff/troff/input.cc (token::next, token::description,
get_line_arg, token::add_to_node_list, token::process): Use it.

2001-01-27 Werner LEMBERG <[email protected]>

First cut of the new html device driver. Changes to pre-html and
the new grohtml are too numerous to be documented here.

Stuff related to `html' has been renamed to `html-old' and `html2'
stuff has been renamed to `html' (including directories). The new
html device driver is therefore invoked as `-Thtml'.

Added new `\O' escape to suppress output (needed by html driver).

Added functions and code to pass info about input-level commands
(`.in', `.fl', etc.) to html driver.

Three new functions (.html-begin, .html-end, and .html-image) for
better html handling: `html-begin' will execute the remaining line
if at the outermost nesting level, increasing an internal counter.
`html-end' does the same but decreases the internal counter.
`html_image' puts its arguments into a special node (suppress_node)
to define an image region.

The `output' request has been removed.

2000-10-09 Werner LEMBERG <[email protected]>

* src/libs/libbib/map.c, src/libs/libgroff/getcwd.c,
src/libs/libgroff/strtol.c, src/preproc/html2/image.cc,
src/preproc/html2/pre-html.cc, src/preproc/html2/pushbackbuffer.cc,
src/roff/groff/pipeline.c: Removing `#ifndef errno' to avoid
compilation errors with some compilers. It seems that this code
is no longer necessary -- if yes, it is easy to add some #ifdef's
for that particular old-fashioned compiler.

* MORE.STUFF: Added info about Meta-tbl.

* doc/groff.texinfo: Added more info about `.if "..."..."'.

2000-10-07 Werner LEMBERG <[email protected]>

Adding a new escape sequence \B'...': If the string between
the delimiters is a valid numeric expression, return the character
`1', and `0' otherwise. This is an analogon to \A.

* src/roff/troff/input.cc (do_expr_test): Implement it.
(token::next): Use it.
* src/roff/troff/troff.man, NEWS, man/groff.man: Document it.

this very special request is needed to make tmac.trace independent
from the escape character (which might even be disabled).

* src/roff/troff/input.cc (do_define_macro): Implement it.
(define_macro_indirect): New function.
(init_input_requests): Use it.

Adding two requests .ecs and .ecr: Save and restore the escape
character. These two requests are needed to make tmac.trace
independent from the escape character (which might even be
disabled).

strings.h from the former to the latter.
* src/devices/grolbp/lpb.cc, src/include/lib.h: Move strncasecmp()
stuff from the former to the latter.

2000-09-11 Werner LEMBERG <[email protected]>

Implementing two new requests .tm1 and .tmc: The former is similar
to .tm but can output leading spaces; its syntax is similar to
defining a string, i.e., a `"' can be used to mark the beginning of
the string to be written to stderr: `.tm1 " test'. The latter is
similar to .tm1 but doesn't write out a final newline character.

* src/roff/troff/input.cc (terminal1, terminal_continue,
do_terminal): New functions.
(init_input_requests): Use them.
* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.

2000-09-09 Werner LEMBERG <[email protected]>

* tmac/groff_mdoc.samples.man: Small fixes.

* font/devps/generate/Makefile (SHELL): Define explicitly to
"/bin/sh", for non-Unix platforms.
(extraclean): Use a more portable "" quoting instead of a
backslash (which doesn't work on DOS/Windows).

* font/devlj4/generate/Makefile (extraclean): Ditto.

* font/devdvi/generate/Makefile (extraclean): Ditto.

src/roff/troff/troff.man: Document Eli's latest changes.

2000-08-25 Eli Zaretskii <[email protected]>

* src/roff/troff/input.cc (open_mac_file, macro_source): Support

still obeying motion) and also the opminx, opminy, opmaxx, opmaxy
registers (for passing the output dimensions to the output device).

* src/roff/troff/div.cc (top_level_diversion::output): Use `width'
parameter.
* src/roff/troff/node.h, src/roff/troff/node.cc
(troff_output_file::really_print_line,
ascii_output_file::really_print_line,
supress_output_file::really_print_line): Use `width' parameter.
(troff_output_file::really_on, troff_output_file::really_off,

* src/roff/groff/groff.cc: Add support for html2 device (which will
automatically invoke the html2 preprocessor).
* src/roff/troff/input.cc (is_html2): New variable.
* src/roff/troff/troff.h, src/roff/troff/env.h,
src/roff/troff/env.cc (environment::add_html_tag): New function
(uses `is_html2').

src/roff/grog/Makefile.sub, src/roff/nroff/Makefile.sub: Updated.

* src/devices/grolbp/lbp.cc: Add an AIX workaround for an autoconf
bug (string.h and strings.h are both needed according to latest
POSIX standard).

* MORE.STUFF: Added info about unroff and troffcvt.

2000-08-08 Werner LEMBERG <[email protected]>

Fix typo: "monocased_shell" no longer exists.

2000-08-07 Paul Eggert <[email protected]>

Remove FILENAME_MAX limits.

* src/roff/groff/pipeline.c (is_system_shell): Do not assume
that the argument length is less than FILENAME_MAX.
* src/libs/libgroff/tmpfile.cc (add_tmp_file): Likewise.
Use struct hack to allocate and free file name.
(struct xtmpfile_list): fname is now part of the structure,
not a pointer to another string.

2000-08-07 Tom Schmidt <[email protected]>

* src/include/posix.h: Add a default value for FILENAME_MAX.

2000-08-06 Paul Eggert <[email protected]>

Add support for new BSD-style man pages (with ".Dd" instead of
".TH"), so that "groff -man" understands both styles, even
when running "groff -man" on a host whose system man page
macros don't support ".Dd".

* tmac/Makefile.sub (NORMALFILES): Add tmac.an.old.
(stamp-wrap): Source tmac.andoc first when wrapping man macros,
in case the system man macros don't define Dd or TH.
