* Divorce css_string from whatever gets stored in lpu hashes.John Mark Bell2008-12-011-3/+3
| | | | | | | | | | | | | | | | | | Use pointers to parserutils_hash_entry directly in stylesheet datastructures. The upshot of this for allzengarden.css is: 5506 slots used (of 8192 => 67.211914%) Data: 8 full blocks: 32768 bytes 9 partial blocks: 35124 bytes (of 36864 => 95.279945%) Total: 69936 (4112) (32) Hash structures: 65584 i.e. a total string dictionary size of 135,520 bytes, which is some 74,056 bytes less than before. svn path=/trunk/libcss/; revision=5859
* More modifications to allow numerous iterations for profiling.John Mark Bell2008-11-303-73/+88
| | | | | | | | | | | Overall time breakdown for allzengarden.css is approximately: lex : 37% core : 43% lang : 20% svn path=/trunk/libcss/; revision=5857
* Modify to allow a configurable number of iterations for profiling.John Mark Bell2008-11-301-27/+43

* Use parserutils_hash instead of parserutils_dict.John Mark Bell2008-11-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | 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 Bell2008-11-274-25/+31
| | | | | | | | | | 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
* Fix rounding when fractional part is close to 1.John Mark Bell2008-11-241-0/+6
| | | | | | Add testcase to exercise this. svn path=/trunk/libcss/; revision=5766

* Some kind of testsuite for number parsing.John Mark Bell2008-11-235-1/+177
| | | | | | It appears that negative values are broken, at least. svn path=/trunk/libcss/; revision=5763

| | | | svn path=/trunk/libcss/; revision=5648
* Provide an internal mechanism for dumping stylesheets to a file handle.John Mark Bell2008-10-191-1/+3
| | | | | | Make the css21 test driver call this so we can see if it's working. svn path=/trunk/libcss/; revision=5602
* Modify CSS2.1 frontend test driver to use the public stylesheet API.John Mark Bell2008-09-251-21/+9
| | | | | | Media type handling may need to change -- 32bits may not be large enough in the long term, and there's no sensible way of extending this without causing ABI breakage in the future. svn path=/trunk/libcss/; revision=5439

* Make selector token vector be associated with the ruleset, rather than ↵John Mark Bell2008-08-051-1/+1
| | | | | | | | | having its own event type. Store details about the current construct on the context stack. Document block-content, selector, and declaration stuff. svn path=/trunk/libcss/; revision=4921
* Change API of event callback to return css_error (this is more useful than bool)John Mark Bell2008-08-041-3/+3
| | | | | | Implement all the context-related event handlers in the stage 2 parser. svn path=/trunk/libcss/; revision=4898
* Only intern strings when we get a token from the lexer. Strings in tokens ↵John Mark Bell2008-08-012-2/+2
| | | | | | that have been pushed back have already been interned, so it's stupid to re-intern every time. This has required that the lexer permits its clients to modify the data members of the css_token object. That's fine, as it assumes nothing about them (they're basically just a window onto the internal lexer state, anyway). svn path=/trunk/libcss/; revision=4857
* Stub out a CSS 2.1 stage 2 parser.John Mark Bell2008-08-014-4/+96
| | | | | | Parser core doesn't need to know about css_stylesheet, so change its API. svn path=/trunk/libcss/; revision=4854

| | | | svn path=/trunk/libcss/; revision=4852
* Fix handling of empty strings.John Mark Bell2008-08-013-0/+7
| | | | | | | | Parse errors in blocks are ignored -- it'll be up to the client to deal with this. Fix processing of malformed decl-list entries (e.g. foo: bar; !important;) Fix test driver to calculate remaining length correctly. svn path=/trunk/libcss/; revision=4849
* Fix at-rule processing.John Mark Bell2008-07-312-1/+9

* Implement the first-stage parser.John Mark Bell2008-07-305-1/+92
| | | | | | | | | | | 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

* Testdriver for automated lexer tests. This needs a little more work to ↵John Mark Bell2008-05-016-1/+302
