* Parse: simplify token vector cleanup.jmb/mqJohn-Mark Bell2019-03-101-42/+22
| | | | | | There's not much point having every call site have to call two functions every time they want to clean the token vector. Instead, have a single function call to do both parts of the cleanup.
* Parse: use an explicit state for media queries.John-Mark Bell2019-03-101-3/+31
| | | | | This simply wraps the existing at-rule parser but is able to clean up afterwards.
* Media queries: remove bogus input to query parser.John-Mark Bell2019-02-181-8/+0

* Media Queries: fix parsing of media-conditionJohn-Mark Bell2019-02-181-5/+6

* Tests: fix illegal display value test.John-Mark Bell2019-02-181-1/+1
| | | | | | | | | Recovery from malformed property values involves matching the various nesting mechanisms. Thanks to the bug in the parseAny state machine, this code was never run. The test data contained mismatched open parentheses, causing the recovery logic to continue reading until EOF. Fix the test input to match the expectations of the test assertions.

* HACKS for testing Media Queries parsing.Michael Drake2018-08-014-3/+141
| | | | | | | | | | | 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.
* Media Queries: Parse only needs propstrings out of css_language.Michael Drake2018-07-303-54/+62

* Media Queries: API for stylesheet import doesn't take media now.Michael Drake2018-07-302-6/+2

* Media Queries: Update stylesheet import for media query lists.Michael Drake2018-07-301-2/+4
|
* Media Queries: Update rule_good_for_media for new mq struct.Michael Drake2018-07-301-6/+44
| | | | | Doesn't currently match media query conditions, only the media type.
* Media Queries: Store type as value, rather than lwc_string.Michael Drake2018-07-302-4/+60
| | | | | | Otherwise we need to convert it in selection, and select/ doesn't have access to the css_language interned strings table.

* Media Queries: datastructures and plumbing.John-Mark Bell2018-07-287-109/+233
| | | | | | | | | | | | | 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.
* Select generator: Squash undefined behaviour in generated code.Michael Drake2018-07-284-603/+621
| | | | | | | uint8_t is promoted to int instead of unsigned, so it can't hold the values we try to store. Reran `make select_generator` to update generated code.

* Parsing: Fix undefined shift in css__parse_hash_colour.Michael Drake2018-07-281-2/+2
| | | | | | | | | | uint a = 0xff; a << 24 `a` gets promoted to int, which can't store the value. src/parse/properties/utils.c:655:16: runtime error: left shift of 255 by 24 places cannot be represented in type 'int' src/parse/properties/utils.c:889:15: runtime error: left shift of 255 by 24 places cannot be represented in type 'int'

* Build: Commit generated computed style access source code.Michael Drake2018-01-066-6/+5259
| | | | | | | | This means python3 is not required to build libcss. To re-generate the compute style access code, e.g. when adding new CSS properties, developers must run `make select_generator` and commit the updated generated source code.
