* css: add reverse video extensionbptato2024-10-151-0/+1
| | | | | | | | | | | | Called -cha-reverse. Mostly to solve the problem that code tags are indistinguishable from regular text - on a graphical browser this is normally served by monospace font, but we always use monospace... So now the default ua.css adds reverse video to code and xmp. pre remains as it was, because it means "preformatted", not "monospaced". Also, it would mess with our whatever-to-HTML converter output.
* color: reduce CellColor size, misc color refactoringbptato2024-10-061-14/+14
| | | | | | * split out CSSColor from CellColor; now CellColor is just 4 bytes (which helps reduce FormatCell size) * unify color function naming (still not perfect)
* layout: remove line-heightbptato2024-09-211-22/+5
| | | | | This was a bad idea that, despite my best efforts, never worked properly.
* Refactor img/*bptato2024-09-151-1/+1
| | | | | I've moved most image logic to adapter, so it doesn't really make sense to have this subdir anymore.
* utils: add twtunibptato2024-09-081-15/+16
| | | | | | | | | | | | | | | | | | | std/unicode has the following issues: * Rune is an int32, which implies overflow checking. Also, it is distinct, so you have to convert it manually to do arithmetic. * QJS libunicode and Chagashi work with uint32, interfacing with these required pointless type conversions. * fastRuneAt is a template, meaning it's pasted into every call site. Also, it decodes to UCS-4, so it generates two branches that aren't even used. Overall this lead to quite some code bloat. * fastRuneAt and lastRune have frustratingly different interfaces. Writing code to handle both cases is error prone. * On older Nim versions which we still support, std/unicode takes strings, not openArray[char]'s. Replace it with "twtuni", which includes some improved versions of the few procedures from std/unicode that we actually use.
* twtstr: type erase binarySearch instantiationbptato2024-09-061-5/+9
| | | | | | | | Do it like parseEnumNoCase0, so we no longer instantiate a gazillion different binary searches for the same type. While we're at it, make matchNameProduction's searchInMap use uint32 too.
* canvas: move to separate CGI scriptbptato2024-09-011-1/+1
| | | | | | | | | | * stream: and passFd is now client-based, and accessible for buffers * Bitmap's width & height is now int, not uint64 * no more non-network Bitmap special case in the pager for canvas I just shoehorned it into the static image model, so it still doesn't render changes after page load. But at least now it doesn't crash the browser.

* cssvalues, twtstr, mediaquery: refactor & fixesbptato2024-08-021-28/+9
| | | | | | | * cssvalues, twtstr: unify enum parsing code paths, parse enums by bisearch instead of hash tables * mediaquery: refactor (long overdue), fix range comparison syntax parsing, make ident comparisons case-insensitive (as they should be)
* cssvalues: fix parseDimensionValues bugbptato2024-07-271-9/+10
| | | | Whitespace-only dimension values no longer crash the parser.
* css: clean up a bitbptato2024-07-121-20/+3

* cssvalues: add "clear" to table wrapper boxbptato2024-06-111-1/+3
| | | | this one is weird but I'm sure the standard is technically right
* css: slightly optimize cascadebptato2024-06-021-72/+4
| | | | Parse rule values in sheet addRule, not during cascade.
* layout: add wrapper box for table caption + misc stuffbptato2024-05-241-15/+35
| | | | | | | | | Captions are no longer positioned inside tables, yay. Also, misc: * rename some things for consistency * clamp out of bounds rgb() values * remove inherited property lookup table
* layout, layoutunit: remove some automatic convertersbptato2024-05-221-5/+5
| | | | | I wish we didn't need any, but fixing this for integers would be too involved and the float64 one was causing problems now.
* css: stub overflowbptato2024-05-181-1/+15
| | | | | The renderer cannot handle it yet, but at least this fixes pages that expect overflow: hidden (etc.) to establish a new BFC.
