* layout: fix intrinsic min width for words with wrapping opportunitiesbptato2024-11-241-11/+18
| | | | | | | This broke CJK combined with table layouts. (Inline layout's state dependencies between procs are getting a bit scary...)
* match, stylednode: remove generics, refactorbptato2024-11-193-137/+91
| | | | | | Turns out the generics weren't really needed in the first place. Also, StyledNode is now 16 bytes smaller.
* layout: fix intrinsic min width with whitespace: prebptato2024-11-191-0/+1
|
* layout: fix indefinitely sized flex items with boundsbptato2024-11-191-1/+8
| | | | maybe I'll get it right one of these days
* layout: fix crash on overlapping rowspan/colspanbptato2024-11-171-2/+3
| | | | | The rowspan filler must get a smaller colspan if its first cells are occupied by another cell with a colspan > 1.
* js: reorganize modules, update docsbptato2024-11-152-2/+2
| | | | | | | most of it has already been moved to monoucha, and the rest fits better in other directories. also, move urimethodmap to config
* cssvalues: reduce CSSComputedValue sizebptato2024-11-145-91/+102
| | | | | | | far from perfect, but it's something. (ideally, we should store enums in a bitmap instead of allocating a GC'ed property for each of them.)
* layout: fix another flex sizing bugbptato2024-11-141-1/+8
|
* layout: remove inline paddingbptato2024-11-131-24/+5
| | | | like line height, this caused more trouble than it was worth
* buffer: fix broken gotoAnchor behaviorbptato2024-11-122-5/+11
| | | | | | | | | | | | | | | | | 23beebe6 introduced a regression that broke gotoAnchor. This fixes that, plus a couple other long-standing gotoAnchor bugs: * If no anchor is found, do not dupe the buffer. Desktop browsers still add a history entry, while w3m prints an error. I've copied the latter because it makes more sense as a user, but this will have to be refined for the navigation API at some point. * If the anchor *is* found, then always jump to it, even if it's not visible. This was a limitation of relying on the line array, so now we rely on the box tree instead. (Sooner or later, the former must go anyway.) Also, fix `U' reload not restoring the position (hopefully this time for good).
* cascade: adjust prefers-color-scheme based on terminal backgroundbptato2024-11-101-1/+1
| | | | also, default link color is now blue for light terminal backgrounds
* layout -> cssbptato2024-11-106-2/+4080
| | | | as much as I wish it weren't, layout *is* css.
* renderdocument: basic stacking context supportbptato2024-11-091-1/+9
| | | | | negative z-index and inline positioning are still not respected, but better than nothing I guess.
* utils, types: merge some modulesbptato2024-11-032-2/+0
| | | | | * line, vector, matrix -> path * twtuni, charcategory -> twtstr
* cssparser: fix parsing of unrecognized at rulesbptato2024-11-022-25/+20
| | | | + clean up a bit
* Clean up forward declarations a bitbptato2024-10-272-4/+5

* selectorparser: fix parsing of invalid pseudo elementsbptato2024-10-261-16/+35
| | | | | Found this because the 5th largest tech company on Earth cannot bother itself with trivial matters such as "writing valid CSS".
* cssparser: do not accept invalid rulesbptato2024-10-251-2/+3
| | | | | | This isn't exactly clear from the standard's wording, but e.g. *display: inline must be discarded (because it incorrectly starts with a delim token).
* 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.
* dom: html -> documentElementbptato2024-10-102-2/+2
| | | | it's effectively a dupe, except html wouldn't work in XML
* color: reduce CellColor size, misc color refactoringbptato2024-10-062-17/+17
| | | | | | * split out CSSColor from CellColor; now CellColor is just 4 bytes (which helps reduce FormatCell size) * unify color function naming (still not perfect)
* dom: optimize element size, remove importc hack & dead codebptato2024-09-301-13/+13
| | | | | This switches CAtom to uint32; it seems better to use the same size on all platforms.
* 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 twtunibptato2024-09-082-26/+26
| | | | | | | | | | | | | | | | | | | 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.
* cascade: add missing nil checkbptato2024-09-021-1/+1

* canvas: move to separate CGI scriptbptato2024-09-012-8/+10
| | | | | | | | | | * 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 & fixesbptato2024-08-023-405/+309
| | | | | | | * 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)

* buffer, pager, config: add meta-refresh + misc fixesbptato2024-07-281-3/+3
| | | | | | | | | * buffer, pager, config: add meta-refresh value, which makes it possible to follow http-equiv=refresh META tags. * config: clean up redundant format mode parser * timeout: accept varargs for params to pass on to functions * pager: add "options" dict to JS gotoURL * twtstr: remove redundant startsWithNoCase
* cssvalues: fix parseDimensionValues bugbptato2024-07-271-9/+10
| | | | Whitespace-only dimension values no longer crash the parser.
* cascade: add some presentational hintsbptato2024-07-271-3/+7
| | | | | | * top/middle/bottom for img, remove redundant display: block for floats (they get blockified anyway) * map align for p too, not just div

* cascade: reduce allocationsbptato2024-07-101-57/+42
| | | | | | | Just use the previous tree when possible. The child list is still reconstructed, but at least we no longer alloc every single node again at every single restyle.
* cascade: fix style cachingbptato2024-07-092-6/+8
| | | | the invalid flag must be toggled after styling
* selectorparser: fix parseNthChild `of' token checkbptato2024-07-071-1/+3
| | | | tokenType had to be checked too
* layout: reduce copiesbptato2024-07-031-2/+5
| | | | | Text data is no longer stored separately in InlineFragments; instead, we now include refs to StyledNodes.
* css, html: fix CSS dependency invalidationbptato2024-07-032-36/+19

* cascade: support align=left, align=right on imgbptato2024-06-291-2/+14

* img, loader: add image resizing, misc fixesbptato2024-06-281-2/+3
| | | | | | | | | | | | | | | * resize images with stb_image_resize * use tee for output handle redirection (redirectToFile blocks) * cache original image files * accept lseek in sandbox * misc stbi fixes For now, I just pulled in stb_image_resize v1. v2 is an extra 150K in size, not sure if it's worth the cost. (Either way, we can always switch later if needed, since the API is almost the same.) Next step: move sixel/kitty encoders to CGI, and cache their output in memory instead of the intermediate RGBA representation.
