* Media Queries: datastructures and plumbing.John-Mark Bell2019-03-101-4/+5
| | | | | | | | | | | | | No parse implementation as yet. Selection hasn't been updated, either. One item of note in that area is that a client currently provides the media for top-level sheets being added to a selection context. This probably needs to change to providing a lwc_string containing the verbatim media query from the containing document's import mechanism. That way, the internal representation of media queries can remain opaque to clients.

* Various changes which modify API and ABI:Michael Drake2013-12-131-3/+0
| | | | | | | | | - 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.

* Remove ownerNode and ownerRule fields from stylesheet objects.John Mark Bell2010-06-271-3/+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

* Origin and media are not properties of the stylesheet. John Mark Bell2010-01-121-3/+0
| | | | | | | | | 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 Bell2009-08-291-1/+2
| | | | | | | | | | | | | | | | | | 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

* Port libcss to libwapcaplet.Daniel Silverstone2009-02-141-12/+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 Bell2009-02-141-5/+6
| | | | | | 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

* Beginnings of specificity. John Mark Bell2009-01-251-0/+4
| | | | | | | | 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

* Make @import actually create a rule and attempt some kind of fetch logic.John Mark Bell2009-01-141-0/+3
| | | | | | | 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

* Given that we're going to be copying selector details, anyway, it seems ↵John Mark Bell2008-12-011-4/+2
| | | | | | 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 Bell2008-12-011-4/+5

* Divorce css_string from whatever gets stored in lpu hashes.John Mark Bell2008-12-011-2/+2
| | | | | | | | | | | | | | | | | | 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 Bell2008-11-301-2/+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
* Optimise css_stylesheet_add_rule by the cunning approach of not iterating ↵John Mark Bell2008-11-281-0/+1
| | | | | | through a singly linked list to find the end every time we want to insert a rule. This doubles parsing speed. svn path=/trunk/libcss/; revision=5811
* Change the way in which css_rules are defined. This is more compact than the ↵John Mark Bell2008-11-281-39/+56
| | | | | | previous approach. Space requirements for rule objects alone is now 447,120 bytes as opposed to 819,270 bytes previously. This reduces the space requirements for allzengarden.css to 2,041,712 bytes, which is 45% the size of what we had originally. svn path=/trunk/libcss/; revision=5810
* css_string is now the same as a parserutils_dict_entry. This allows us to ↵John Mark Bell2008-11-271-13/+23
| | | | | | | | | | 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

* Parse common part of declarations.John Mark Bell2008-10-221-3/+6

* Style information for selector rulesets can be shared between the individual ↵John Mark Bell2008-10-201-2/+1
| | | | | | selectors in the ruleset. Therefore, hang it off the css_rule object, rather than having a separate copy for every selector in the ruleset. Selectors know which css_rule they belong to so can easily find the applicable style information. svn path=/trunk/libcss/; revision=5609
* Provide an internal mechanism for dumping stylesheets to a file handle.John Mark Bell2008-10-191-0/+3
| | | | | | Make the css21 test driver call this so we can see if it's working. svn path=/trunk/libcss/; revision=5602
