* Avoid integer types with platform dependent sizeDeltaVonNeumann2023-06-171-12/+12

* Parse/MQ: unknown media-types do not matchJohn-Mark Bell2022-05-241-4/+1
| | | | | | | | Per https://www.w3.org/TR/mediaqueries-4/#error-handling, "An unknown <media-type> must be treated as not matching" Ensure, however, that a rule with a condition and no type behaves as if type was all.
* Parse/MQ: reject forbidden media-type identifiersJohn-Mark Bell2022-05-241-15/+40
| | | | | | "and" / "not" / "only" / "or" are forbidden, so must be rejected Add tests for these scenarios
* Media queries: Don't set parts before allocation has failed.Michael Drake2020-02-241-1/+1
| | | | | | | Squashes scan-build error about dereference of parts if the allocation fails. Signed-off-by: Michael Drake <Michael Drake tlsa@netsurf-browser.org>
* Media queries: Tweak mq_parse_media_in_parens return style.Michael Drake2019-06-121-3/+4

* Media queries: Squash an invalid warning from certain compilers.Michael Drake2019-06-091-1/+1
| | | | src/parse/mq.c:1125:15: error: 'query' may be used uninitialized in this function [-Werror=uninitialized]
* Media queries: Handle errors in a media query list correctly.Michael Drake2019-06-091-8/+39

* Media queries: Squash error-path leaks of feature names.Michael Drake2019-06-051-3/+3
|
* Media queries: <ratio> isn't allowed to have 0 numerator or denominator.Michael Drake2019-06-051-0/+4
| | | | | | | | | | The <ratio> value type is a positive (not zero or negative) <integer> followed by optional whitespace, followed by a solidus ('/'), followed by optional whitespace, followed by a positive <integer>. <ratio>s can be ordered or compared by transforming them into the number obtained by dividing their first <integer> by their second <integer>. -- https://www.w3.org/TR/mediaqueries-4/#aspect-ratio
* Media queries: Pass the right tokens to mq_populate_value.Michael Drake2019-05-061-2/+2

* Media queries: A query without a type defaults to type: all.Michael Drake2019-05-061-2/+6
|
* Media queries: Convert to level 4 range in the correct place.Michael Drake2019-05-061-6/+6
| | | | | In mq_parse_range we already have a level 4 range. We need to convert <mf-plain> in mq_parse_media_feature.
* Media queries: Reverse operator for level 4 range conversion.Michael Drake2019-05-061-2/+2
| | | | First op/value are encoded as `value op name`.
* Media queries: Parse: Convert level 3 style ranges to level 4.Michael Drake2019-05-051-0/+57
| | | | This will make the selection code's life easier.
* Media queries: Intern the query descriptor name as lower case.Michael Drake2019-05-051-1/+4

* Media queries: Move css_parse_media_query to parse/mq.c file.Michael Drake2019-03-101-0/+103
| | | | It's now exposed in the mq.h header too.
* Media queries: Ensure values get destroyed.Michael Drake2019-03-101-5/+16

* Media Queries: Parse only needs propstrings out of css_language.Michael Drake2019-03-101-51/+57
|
* Media Queries: Store type as value, rather than lwc_string.Michael Drake2019-03-101-3/+59
| | | | | | Otherwise we need to convert it in selection, and select/ doesn't have access to the css_language interned strings table.

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.
