From d5d8909e11e0c613f7a1dfba3a20a405ae7b4da4 Mon Sep 17 00:00:00 2001 From: wl Date: Mon, 13 Dec 2010 15:30:19 +0000 Subject: 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 and . (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. --- ChangeLog | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index d59fd991..e47e1a0b 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,37 @@ +2010-12-06 Colin Watson + Daiki Ueno + + 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 and . + (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 [grohtml]: Improve texinfo documentation. -- cgit v1.2.1
