* Fix renaming of css_parser_parse_chunk from css_parser_css__parse_chunk to ↵Daniel Silverstone2011-01-261-1/+1
| | | | | | css__parser_parse_chunk svn path=/trunk/libcss/; revision=11491
* Ensure there are zero global symbols without css_ or css__ in front of them. ↵Daniel Silverstone2011-01-201-1/+1
| | | | | | This helps prevent confusion if someone else wants a function called parse_background or similar svn path=/trunk/libcss/; revision=11416
* Merge parser autogeneration and string handling refactor branch ↵Vincent Sanders2011-01-191-118/+170

* Add string vector capability to stylesheet (r=jmb)Vincent Sanders2010-12-051-0/+85
| | | | | | Move properties ready for split svn path=/trunk/libcss/; revision=11005
* Provide notification hook for imported stylesheets, to enable clients to ↵John Mark Bell2010-12-051-0/+6
| | | | | | parallelise their processing svn path=/trunk/libcss/; revision=10999
* Remove ownerNode and ownerRule fields from stylesheet objects.John Mark Bell2010-06-271-2/+0
| | | | | | | | | | | These prevent stylesheets being used in multiple contexts simultaneously. Their values can be inferred from the context in which the stylesheet is used. Replace use of ownerRule to backtrack in style selection with a (fixed-size) stack of rules to process. This prevents crashes when a sheet that was previously imported somewhere is reused as a top-level sheet. svn path=/trunk/libcss/; revision=10581
* Ownership of imported stylesheets is retained by the client.John Mark Bell2010-04-111-3/+2
| | | | svn path=/trunk/libcss/; revision=10367
* Fix RISC OS buildJohn Mark Bell2010-04-051-3/+3

* Do not unref strings referenced by bytecode we've just copied when appending ↵John Mark Bell2010-03-281-2/+2
| | | | | | to a rule's style. svn path=/trunk/libcss/; revision=10174
* Make libcss suitable for the new libwapcaplet behaviour.Daniel Silverstone2010-03-281-143/+157
| | | | svn path=/trunk/libcss/; revision=10168
* Fix libcss to use new libwapcaplet behaviour.Daniel Silverstone2010-03-271-22/+16
| | | | | | | TODO: update the tests to include a refcounting proof svn path=/trunk/libcss/; revision=10162
* Origin and media are not properties of the stylesheet. John Mark Bell2010-01-121-41/+1
| | | | | | | | | They are properties of the context in which the stylesheet is used. Therefore, for top-level sheets, this information must be provided at selection time. For child sheets, the origin is inherited from their parent and the applicable media types are specified on the linking mechanism. svn path=/trunk/libcss/; revision=9802
* 1) Allocate css_style bytecode in 16 byte chunksJohn Mark Bell2009-08-291-13/+66
| | | | | | | | | | | | | | | | | | 2) Cache unused css_style objects with chunks of size 16, 32, 48, and 64 bytes The above should reduce heap churn somewhat. Further improvements are possible: 1) Make the property parsers write the parsed values direct into the output bytecode, instead of into a temporary object which is then merged into the output. 2) Perform similar caching for css_rule and selector objects. 3) Shrink-wrap finalised output styles rather than leaving them oversized. 4) Perform measurement to determine the optimal chunk sizes (power-of-2 makes maths simple and 16 is plucked from thin air) and cache bucket count/sizes. svn path=/trunk/libcss/; revision=9502
* Calculate the in-memory size of stylesheets and provide some API to access this.John Mark Bell2009-07-271-0/+137
| | | | svn path=/trunk/libcss/; revision=8830
* Fix selector hash some more. It turns out that I'd forgotten how it was ↵John Mark Bell2009-07-171-1/+2
| | | | | | meant to work. svn path=/trunk/libcss/; revision=8607
* Fix processing of rules after @import -- previously, they were completely ↵John Mark Bell2009-07-081-0/+2
| | | | | | ignored. svn path=/trunk/libcss/; revision=8386
* Len already includes the NUL, so stop trying to manually terminate url/title.John Mark Bell2009-07-011-2/+0

* Make all URIs absoluteJohn Mark Bell2009-07-011-1/+10

* Support for parsing inline stylesJohn Mark Bell2009-06-261-7/+22

* Nested block support.John Mark Bell2009-06-261-71/+114
| | | | svn path=/trunk/libcss/; revision=8014
* Most of the interned string lifetimes are at least no shorter than we think ↵Daniel Silverstone2009-02-151-6/+41
| | | | | | they ought to be. svn path=/trunk/libcss/; revision=6532
* Quirks mode parsingJohn Mark Bell2009-02-151-2/+53
| | | | svn path=/trunk/libcss/; revision=6519
* Port libcss to libwapcaplet.Daniel Silverstone2009-02-141-26/+11
| | | | | | | | | 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
* Rework handling of imported stylesheets.John Mark Bell2009-02-141-15/+139
| | | | | | No longer is the client called back mid-parse. Instead, they must acquire details of and process imported stylesheets after css_stylesheet_data_done() has been called on the parent sheet. The return code of css_stylesheet_data_done() informs the client of the need to process imported sheets. svn path=/trunk/libcss/; revision=6504
* Drop css_error_handler and rename css_alloc to css_allocator_fnDaniel Silverstone2009-02-141-1/+1
| | | | svn path=/trunk/libcss/; revision=6482
* Discard selectors that contain pseudo elements in non-terminal simple selectors.John Mark Bell2009-02-141-2/+10
| | | | | | More test data for selectors with pseudo elements svn path=/trunk/libcss/; revision=6473
* Synchronise media type bitfield with reality -- it's 64bits wide.John Mark Bell2009-02-121-2/+2
| | | | svn path=/trunk/libcss/; revision=6453
* Distinguish between pseudo classes and pseudo elementsJohn Mark Bell2009-02-101-5/+2
| | | | svn path=/trunk/libcss/; revision=6406
* Use a chaining hash for selectors -- permits easy sorting of hash entries by ↵John Mark Bell2009-01-261-4/+6
| | | | | | specificity/rule index. svn path=/trunk/libcss/; revision=6280
* Propagate specificity of simple selectors to the head of each combinator chain.John Mark Bell2009-01-261-0/+3
| | | | | | This saves us having to calculate the specificity every time we want it. svn path=/trunk/libcss/; revision=6278
* Assert preconditions, rather than returning runtime errors.John Mark Bell2009-01-251-19/+22
| | | | | | Squash leakage of selectors array in selector/page rules. svn path=/trunk/libcss/; revision=6274

* Clean up rules when destroying sheetJohn Mark Bell2009-01-251-1/+12
| | | | svn path=/trunk/libcss/; revision=6271
* Destroy rulesJohn Mark Bell2009-01-251-4/+81
| | | | svn path=/trunk/libcss/; revision=6269
* Destroy selectorsJohn Mark Bell2009-01-251-5/+17
| | | | svn path=/trunk/libcss/; revision=6268
* Beginnings of specificity. John Mark Bell2009-01-251-2/+28
| | | | | | | | Note that we store the specificity on each simple selector. Thus the total specificity for a combinator chain is obtained by summing the specificity of each chain member. TODO: distinguish between pseudo classes and elements. svn path=/trunk/libcss/; revision=6267
* Simplify API of css_stylesheet_selector_create -- it's always used to create ↵John Mark Bell2009-01-251-7/+4
| | | | | | element selectors. Everything else is handled via detail. svn path=/trunk/libcss/; revision=6266
* Destroy style objectsJohn Mark Bell2009-01-251-3/+3
| | | | svn path=/trunk/libcss/; revision=6265
* Destroy parser on completion of parse, rather than keeping it around until ↵John Mark Bell2009-01-251-11/+26
| | | | | | we destroy the sheet. svn path=/trunk/libcss/; revision=6264
* Selector hash.John Mark Bell2009-01-251-2/+13
| | | | svn path=/trunk/libcss/; revision=6263
* Purge stylesheet dumping code from the library.John Mark Bell2009-01-191-234/+0
| | | | | | | Create a common header for the test harnesses to use, instead. Fix z-index dumping while we're at it. svn path=/trunk/libcss/; revision=6146
* Don't build the serialisation code in release modeJohn Mark Bell2009-01-141-0/+2
| | | | svn path=/trunk/libcss/; revision=6064
* Make @import actually create a rule and attempt some kind of fetch logic.John Mark Bell2009-01-141-0/+26
| | | | | | | There's still a bunch of outstanding functionality here (like URL resolution and media list parsing). Also, there's currently no way of telling the client to stop fetching data for a stylesheet (and, more importantly, not to attempt to access the stylesheet again as it's about to be destroyed) svn path=/trunk/libcss/; revision=6062
* Create charset rule objects.John Mark Bell2009-01-141-0/+26
| | | | svn path=/trunk/libcss/; revision=6059
* Given that we're going to be copying selector details, anyway, it seems ↵John Mark Bell2008-12-011-41/+11
| | | | | | pointless to create objects on the heap which can equally well be on the stack, given the shortness of their lifetime. svn path=/trunk/libcss/; revision=5863
* Retain pointer to dictionary entries so we don't have to rediscover it later.John Mark Bell2008-12-011-48/+9
| | | | svn path=/trunk/libcss/; revision=5862
* Divorce css_string from whatever gets stored in lpu hashes.John Mark Bell2008-12-011-4/+6
| | | | | | | | | | | | | | | | | | 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
* Use parserutils_hash instead of parserutils_dict.John Mark Bell2008-11-301-10/+10
| | | | | | | | | | | | | | | | | | | | | | 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
* Tidy things up somewhat.John Mark Bell2008-11-281-13/+5
| | | | | | css21 is now language, as everything will share the same parsing rules (although there is facility to alter behaviour based upon the language level -- consult language->sheet->level and then decide what to do) svn path=/trunk/libcss/; revision=5815
