* Add end-block-content parse eventDaniel Silverstone2019-12-011-0/+1
| | | | | | | | | | | | | | | In order to cope with a situation where a block ends with a selector which has no ruleset, add an end-block-content event and in handling it, pop any intermediate states off the language stack so that we're in block mode by the time the event is completed. This fixes an assert situation caused by a ruleset such as: @media screen { dodgy } .outer { top: 10px; } Which has been encountered in the wild (likely a typo).

* HACKS for testing Media Queries parsing.Michael Drake2019-03-101-0/+2
| | | | | | | | | | | Top level stylesheets need to have their media query passed in. So we need a way to parse standalone media queries. This was hacked together to explore doing that. However, it encounteded an issue where it seems the parseAtRule() function in src/parse/parse.c doesn't handle the full grammar for media queries.

* Various changes which modify API and ABI:Michael Drake2013-12-131-3/+1
| | | | | | | | | - Remove client allocation function. - Change node_classes callback not to yield array ownership to libcss. - Node bloom filters now built by, during selection libcss. - Added selection callbacks to get and set data on document nodes. Test suite, example, and documentation updated to match.

| | | | | | | | | It passes the tests, perhaps we need more of them. Lifetimes of lwc_string objects really need attention before we can consider this finished. svn path=/trunk/libcss/; revision=6517

* 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
