* Retain pointer to dictionary entries so we don't have to rediscover it later.John Mark Bell2008-12-011-1/+1

* Use parserutils_hash instead of parserutils_dict.John Mark Bell2008-11-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | This approximately halves the size of the interned string table. We now have the following for allzengarden.css: 5507 slots used (of 8192 => 67.224121%) Data: 3 full blocks: 12288 bytes 10 partial blocks: 38946 bytes (of 40960 => 95.083008%) Total: 53488 (4112) (32) Entries: 21 full blocks: 86016 bytes 1 partial blocks: 2096 bytes (of 4096 => 51.171875%) Total: 90496 (4112) (32) Hash structures: 65592 Which gives a total dictionary size of 209,576 bytes. Note that 43% of this is parserutils_hash_entry structures (length-pointer pairs). It would be good, therefore, to be able to purge these. svn path=/trunk/libcss/; revision=5852
* css_string is now the same as a parserutils_dict_entry. This allows us to ↵John Mark Bell2008-11-271-1/+3
| | | | | | | | | | use dict entries directly as strings. iChange the way in which selectors are represented. This significantly reduces memory requirements -- reducing the approximate usage count (excludes the string dictionary, which is about 360k) of allzengarden.css from 4,535,400 bytes to 2,414,312 bytes on a 64bit platform. The string dictionary is now created and owned by the stylesheet object. The parser is just given access to this so that it can store strings in it. svn path=/trunk/libcss/; revision=5809

* Change API of event callback to return css_error (this is more useful than bool)John Mark Bell2008-08-041-1/+1

* Stub out a CSS 2.1 stage 2 parser.John Mark Bell2008-08-011-2/+3
| | | | | | Parser core doesn't need to know about css_stylesheet, so change its API. svn path=/trunk/libcss/; revision=4854

* Implement the first-stage parser.John Mark Bell2008-07-301-0/+45
Things missing: 1) Recovery after parse errors 2) Event emission (the locations of DEBUG_EVENTS are about right for this) 3) A second-stage parser 4) Any kind of testsuite svn path=/trunk/libcss/; revision=4825
