| | | | | | Fixes scan-build: Value stored to 'error' is never read. Signed-off-by: Michael Drake <Michael Drake tlsa@netsurf-browser.org>

* Add end-block-content parse eventDaniel Silverstone2019-12-013-1/+40
| | | | | | | | | | | | | | | In order to cope with a situation where a block ends with a selector which has no ruleset, add an end-block-content event and in handling it, pop any intermediate states off the language stack so that we're in block mode by the time the event is completed. This fixes an assert situation caused by a ruleset such as: @media screen { dodgy } .outer { top: 10px; } Which has been encountered in the wild (likely a typo).

* 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: 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: Move css_parse_media_query to parse/mq.c file.Michael Drake2019-03-102-0/+107
| | | | It's now exposed in the mq.h header too.
* Parse: simplify token vector cleanup.John-Mark Bell2019-03-101-48/+28
| | | | | | 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.

* HACKS for testing Media Queries parsing.Michael Drake2019-03-103-1/+21
| | | | | | | | | | | 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 Drake2019-03-103-54/+62
|
* Media Queries: Store type as value, rather than lwc_string.Michael Drake2019-03-102-4/+60
| | | | | | Otherwise we need to convert it in selection, and select/ doesn't have access to the css_language interned strings table.
