* Improve CJK support with new values for `.cflags'.wl2010-12-181-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
