(glyph_node::merge_glyph_node): Restore previous version. (break_char_node): Add `prev_break_code' field and update 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.
* Speed up access to cflags values.wl2010-12-202-19/+58
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Improve CJK support with new values for `.cflags'.wl2010-12-183-19/+286
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Fix compilation problem.wl2010-12-152-8/+8
| | | | | | | | 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.
* Remove unused code.wl2010-12-152-7/+1
| | | | | * src/roff/troff/node.cpp, src/roff/troff/node.h (space_node::space_node): Remove unused constructor.
* Use enum to increase readability.wl2010-12-151-7/+13
| | | | | * src/roff/troff/node.cpp (break_char_type): New enum. (break_char_node::add_self, node::add_char): Use it.
* Add wide character support to grotty.wl2010-12-132-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* `.class' must not emit empty lines.wl2010-12-131-0/+2
| | | | | * src/roff/troff/input.cpp (define_class): Add missing `skip_line' calls.
* Implement support for character classes.wl2010-12-132-10/+216
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
