Version 1.21 released 2010-12-31

Documentation updates.
* NEWS, PROBLEMS, MANIFEST: Update.
2010-12-26 Werner LEMBERG <[email protected]>
Speed up troff.
* src/include/ptable.h (PTABLE): Make hash tables much more sparse
by changing the ratio `FULL_NUM/FULL_DEN' from 2/3 to 1/4. This
increases the allocated memory by about 200kByte (which is nothing
today) but assures that there aren't extremely long searches for a
free hash slot in case that the hash function doesn't return a free
one. Due to the nature of the entries in uniuni.cpp, the used hash
function in ptable.cpp is not optimal, but using a sparse array
compensates this.
2010-12-20 Werner LEMBERG <[email protected]>
Replace patch from 2010-12-18 with a much faster implementation.
* src/roff/troff/node.h (node): Add virtual function
`get_break_code'.
* src/roff/troff/node.cpp (inter_char_space_node): Remove class
completely.
(glyph_node::merge_glyph_node): Restore previous version.

constructors.
(node::get_break_code, break_char_node::get_break_code): Implement.
(node::add_char): Pass remaining cflags values.
(break_char_node::add_self): Use the logic of the now deleted
`inter_char_space_node::add_self' function to insert a space node if
necessary.
2010-12-20 Daiki Ueno <[email protected]>
A new try to not changing srcdir if building in separate builddir.
Makefile.in ($GNULIBDIRS): Disable calls to autoconf and friends.
2010-12-20 Werner LEMBERG <[email protected]>
Speed up access to cflags values.
We now recompute the cflags values for all charinfo objects if
`.class' has been called.
* src/roff/troff/charinfo.h: Add external references to `class_flag'
and `get_flags'.
(charinfo): `get_flags' no longer has a return value.
(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
charinfo::can_break_before, charinfo::can_break_after,
charinfo::can_break_after, charinfo::ends_sentence,
charinfo::transparent,, charinfo:ignore_hcodes,
charinfo::prohibit_break_before, charinfo::prohibit_break_after,
charinfo::inter_char_space): Call global `get_flags' only if
necessary.
(charinfo::add_to_class): Set `class_flag'.
* src/roff/troff/input.cpp (class_flag): New global flag.
(charinfo::charinfo): Call `get_flags' member function.
(get_flags): New global function which iterates over all entries in
the charinfo dictionary.
(charinfo::get_flags): Set `flags' directly.
2010-12-19 Werner LEMBERG <[email protected]>
Protect `.class' against cyclic nesting.
* src/roff/troff/charinfo.h (charinfo::contains): Add optional
boolean argument.
* src/roff/troff/input.cpp (define_class, charinfo::contains): Check
for cyclic nesting.
2010-12-18 Werner LEMBERG <[email protected]>
Improve CJK support with new values for `.cflags'.
This patch introduces three new values to `.cflags':
don't break before character: 128
don't break after character: 256
allow inter-character break: 512
They are handled differently if compared to other cflags values:
(1) hcode values are completely ignored
(2) similar to kern values, and contrary to the other cflags
values, troff looks at pairs of characters to decide whether a
break gets inserted
A yet-to-be-written patch should add inter-character spacing if
those flags are active; currently, only zero-width breakpoints are
inserted.
* src/roff/troff/charinfo.h (charinfo): Change type of `flags' to
`int'. Update callers accordingly.
New enum values `DONT_BREAK_BEFORE', `DONT_BREAK_AFTER', and
`INTER_CHAR_SPACE'.
New member functions `prohibit_break_before',
`prohibit_break_after', and `inter_char_space'.
* src/roff/troff/input.cpp: Updated.
* src/roff/troff/node.cpp (inter_char_space_node): New class similar
to kern_pair_node, collecting charinfo entities with the
abovementioned cflags values.
(break_char_type): Add new enum values.
(glyph_node::merge_glyph_node): Handle abovementioned cflags values
and emit an `inter_char_space_node' if necessary.
* tmac/ja.tmac: Use new cflags values.
* doc/groff.texinfo, NEWS, man/groff_diff.man: Document new values.
2010-12-18 Werner LEMBERG <[email protected]>
Remove compiler warning.
* src/libs/libgroff/relocate.cpp (msw2posixpath): Remove redundant
dereferencing.
2010-12-16 Daiki Ueno <[email protected]>
Don't change srcdir if building in a separate builddir.
* Makefile.in ($GNULIBDIRS): Copy configuring stuff of gnulib if
necessary.
2010-12-15 Werner LEMBERG <[email protected]>
Fix compilation problem.
This issue happens with gcc 4.2.4.
* src/roff/troff/node.cpp (node::~node): Move to...
* src/roff/troff/node.h: Here. This ensures that the inline
member function is publicly visible.
2010-12-15 Werner LEMBERG <[email protected]>
Remove unused code.
* src/roff/troff/node.cpp, src/roff/troff/node.h
(space_node::space_node): Remove unused constructor.
2010-12-15 Werner LEMBERG <[email protected]>
Use enum to increase readability.
* src/roff/troff/node.cpp (break_char_type): New enum.
(break_char_node::add_self, node::add_char): Use it.
2010-12-13 Daiki Ueno <[email protected]>
Werner LEMBERG <[email protected]>
Add wide character support to grotty.
This is a huge patch, mainly by adding the gnulib infrastructure in
a separate directory tree (in `src/libs/gnulib/lib') for its
`wcwidth' module. However, the actual changes to native groff
source files are just a few lines.
* Makefile.comm (INCLUDES): Updated.
(LIBGNU): Define.
* Makefile.in (NOMAKEDIRS): Updated.
(GNULLIBDIRS): Define.
(DISTDIRS): Add GNULLIBDIRS.
($LIBDIRS): Depend on GNULLIBDIRS.
($GNULLIBDIRS): New target.
* src/libs/libgroff/font.cpp (font::get_width, font::load)
[is_unicode]: Use `wcwidth'.
* src/roff/troff/Makefile.sub (XLIBS): Add LIBGNU.
* src/roff/troff/input.cpp (main): Set LC_CTYPE.
* src/devices/grotty/Makefile.sub (XLIBS): Add LIBGNU.
* src/devices/grotty/tty.cpp (main): Set LC_CTYPE.
* src/libs/gnulib/*: New files. The import was done as follows:
. Call
gnulib-tool --create-testdir \
--dir=src/libs/gnulib \
wcwidth
to get a testbed.
. Manually move directories src/libs/gl{lib,m4} to
src/libs/{lib,m4}, and do s/gllib/lib/ and s/glm4/m4/ everywhere
to `convert' the gnulib testbed to a standard gnulib
configuration as maintained by gnulib-tool.
. Call
gnulib-tool --add-import \
--dir=src/libs/gnulib \
wcwidth
to update everything.
2010-12-13 Werner LEMBERG <[email protected]>
`.class' must not emit empty lines.
* src/roff/troff/input.cpp (define_class): Add missing `skip_line'
calls.
2010-12-06 UKAI Fumitoshi <[email protected]>
Colin Watson <[email protected]>
Add Japanese localization.
* tmac/ja.tmac: New file.
* tmac/Makefile.sub (NORMALFILES): Updated.
2010-12-06 Colin Watson <[email protected]>
Daiki Ueno <[email protected]>
Implement support for character classes.
This patch uses standard C++ headers, contrary to the rest of groff.
Ideally, everything in groff should be updated to do the same.
* src/include/font.h (glyph_to_unicode): New function.
* src/libs/libgroff/font.cpp (glyph_to_unicode): Implement it.
(font::contains, font::get_code): Use it.
* src/roff/troff/charinfo.h: Include <vector> and <utility>.
(charinfo): New members `ranges' and `nested_classes'.
New member functions `get_unicode_code' and `get_flags'.
New member functions `add_to_class', `is_class', and `contains'.
(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
charinfo::can_break_before, charinfo::can_break_after,
charinfo::can_break_after, charinfo::ends_sentence,
charinfo::transparent,, charinfo:ignore_hcodes): Use `get_flags',
which handles character classes also.
* src/roff/troff/input.cpp (char_class_dictionary): New global
variable.
(define_class): New function.
(init_input_requests): Register `class'.
(charinfo::get_unicode_code, charinfo::get_flags,
charinfo::contains): Implement it.
* NEWS, doc/groff.texinfo (Character Classes), man/groff_diff.man,
man/groff.man: Document it.
2010-11-11 Anton Shepelev <[email protected]>
[grohtml]: Improve texinfo documentation.
* doc/groff.texinfo (grohtml): Insert man page description, slightly
extended.
2010-11-11 Werner LEMBERG <[email protected]>
Fix crash in tbl with option `nospaces'.
Reported by Louis Guillaume <[email protected]>.
* src/libs/libgroff/string.cpp (string::remove_spaces): If input
data consists of spaces only and thus reduces to nothing, set `sz'
to 0.
2010-11-02 Ulrich Spörlein <[email protected]>
[mdoc]: Complete previous patch and document OpenBSD releases.
* tmac/doc-common (doc-operating-system-NetBSD): Add versions 5.0,
5.0.1, and 5.0.2.
(doc-operating-system-OpenBSD-*): New strings.
(doc-operating-system-FreeBSD-*): Add version 8.1.
(doc-operating-system-DragonFly-*): Add versions 2.2, 2.4, 2.6, and
2.8.
(Os): Handle DragonFly and OpenBSD.
* tmac/groff_mdoc.man: Document OpenBSD releases.
Add DragonFly release 2.8.
2010-11-02 Ulrich Spörlein <[email protected]>
[mdoc]: Improve man page.
* tmac/groff_tmac.man: Fix prologue macro order.

[troff]: Fix hyphenation problem with kerned letters.
Problem reported by Steve Izma <[email protected]>.
* src/roff/troff/node.cpp
(kern_pair_node::add_discretionary_hyphen): Compute `tf' using the
first node, `n1'. `n2' might be another kerning node, and the
`get_tfont' member function isn't defined then.
2009-09-01 Michael Cain <[email protected]>
[pic] Fix a border case for arc computation.
* src/preproc/pic/object.cpp (object_spec::make_arc): It can happen
that test `radius < d' in the loop is satisfied, but the difference
in the two values is on the order of 1e-10. If `radius' is small,
doubling the value can lead to a fairly gross error.
The original code appears to have been intended to deal with the
situation when radius is orders of magnitude less than `d'. The
replacement code simply assigns `radius' the smallest value that
avoids problems with the floating point code further on in the
routine.

pic: Fix handling of nested positions.
Reported by Doug McIlroy <[email protected]>.
* src/preproc/pic/pic.y: Split `expr' into `expr_lower_than' and
`expr_not_lower_than' so that we can handle
(1/3)<(1/2)<foo,bar>,baz>
correctly. Without the patch, `(1/3)<(1/2)' is handled prematurely
as a comparison.
2009-05-07 Werner LEMBERG <[email protected]>
Accept \0 and friends within \o.
Reported by Doug McIlroy <[email protected]>.
* src/roff/troff/token.h (token): Add TOKEN_HORIZONTAL_SPACE

Documentation is now by default installed into something like
`/usr/local/share/doc/groff-1.20.1'.
