* Allow non-RGB colors in CSSbptato2024-02-242-51/+99
| | | | | | | | | | | The -cha-ansi color type now sets ANSI colors in CSS. Also, color correction etc. has been improved a bit: * don't completely reset output state in processFormat for new colors * defaultColor is now separated from ANSI color type 0 * bright ANSI colors are no longer replaced with bold + dark variant * replaced ANSI color map to match xterm defaults
* css: reduce CSSComputedValue sizebptato2024-02-172-118/+96
| | | | | | | The `t' field was completely redundant, as it's already included in the CSSComputedValues index. + removed some unused functions
* layout: use html/body bgcolor as canvas bgcolorbptato2024-02-172-4/+15
| | | | | | This is required by the standard. (Without this, lots of websites have incorrect background colors, because they set the body height to 100% of the viewport.)
* css: hide noscript tags when scripting is enabledbptato2024-02-132-3/+25

* twtstr: misc refactoringsbptato2024-02-091-1/+1
| | | | | | * move out half width <-> full width converters * snake_case -> camelCase * improve toScreamingSnakeCase slicing
* buffer: load external resources when they are attachedbptato2024-02-081-0/+2
| | | | | We no longer have to wait for the entire document to be loaded to start loading CSS.

| | | | | | | | * Update chame to the latest version * Get rid of nodeType usage * Add atoms * Re-implement DOM attributes * document.write
* Use errDOMException template everywherebptato2024-01-111-7/+7
|
* Fix windowChange not refreshing valid media queriesbptato2024-01-101-1/+2
| | | | | | | | * css/cascade: copy stylesheet in applyMediaQuery (so that changes are reverted on re-style) * buffer: clear prevstyled in windowChange (to avoid using cached results from previous cascading passes); set window.attrs * pager: avoid windowChange if new attrs are identical to the old ones
* Use std/* imports everywherebptato2024-01-077-23/+23
|
* css/sheet: skip media queries without blocksbptato2024-01-041-0/+3
| | | | Without this, media queries without a block would crash the buffer.
* Compile with styleCheck:usagesbptato2023-12-282-8/+8
| | | | much better
* Move http out of main binarybptato2023-12-131-1/+1
| | | | | | | | | | | | Now it is (technically) no longer mandatory to link to libcurl. Also, Chawan is at last completely protocol and network backend agnostic :) * Implement multipart requests in local CGI * Implement simultaneous download of CGI data * Add REQUEST_HEADERS env var with all headers * cssparser: add a missing check in consumeEscape
* css: add case-insensitive matchingbptato2023-12-112-18/+82
| | | | Also case-sensitive, but for now that is the same as normal matching...
* css: add text-transformbptato2023-12-111-5/+29
| | | | | | | Probably not fully correct, but it's a good start. Includes proprietary extension -cha-half-width, which converts full-width characters to half-width ones.
* sheet: fix overflow in addAtRulebptato2023-12-091-1/+1
| | | | It is enough to just take the len of children there.
* cascade: simplifybptato2023-12-091-2/+1
|
* cascade: fix regressionbptato2023-12-091-18/+23
| | | | | Styled children must be added to their parents *before* they are styled, because match expects this to hold.
* selectorparser: enum-ize relbptato2023-12-092-25/+35
|
* sheet: fix a correctness issue, misc refactoringsbptato2023-12-092-51/+63
| | | | | | | * Fix a bug where rules would be sorted incorrectly if retrieved from the cache. * Use withValue where possible * camelCase some variables, de-extern some functions, etc.
* cascade: refactor & optimizebptato2023-12-091-153/+192
| | | | | | * Break up applyRules into smaller functions * Do not call calcRules for every child pseudo element separately; just use parent's DeclarationListMap
* layout: add clear, etc.bptato2023-11-231-4/+25
| | | | | | * Add clear CSS property * Fix some margin resolution bugs * Apply min-height, max-height to inner inline outer block boxes
* css/values: use Opt instead of Result[string]bptato2023-11-211-55/+54
| | | | the error values were 100% unused
* css/values: simplify getComputedValuebptato2023-11-211-11/+10
|
* css: add box-sizingbptato2023-11-211-4/+21
|
* twtstr: remove tolower, isWhitespacebptato2023-11-201-5/+6
| | | | | | | | * tolower: strutils toLowerAscii is good enough for the cases where we need it. Also, it's easy to confuse with unicode toLower and vice versa. * isWhitespace: in AsciiWhitespace is more idiomatic. Also has a naming collision with unicode toLower.
* layout: add floatsbptato2023-11-172-4/+7
| | | | | | | | | | | | | yay!!!! * Add support for float: left, float: right Also, misc stuff: * Add support for display: flow-root * Set line width to the maximum allowed width on line wrap * Various refactorings Still todo: support clear
* layout: refactor flow margin propagation, sizingbptato2023-11-121-0/+13
| | | | | | | | | * Blocks are now positioned before their text contents would be layouted * Untangle calcAvailableSpaceSizes's results from BlockBox * Move a couple of objects from box -> engine * Use Size in a few more places * Set display to block if float is not none
* dom: add some CSSStyleDeclaration functionsbptato2023-10-252-2/+8
|
* reduce new() usagebptato2023-10-251-4/+5
|
* Add jspropnames, CSSStyleDeclaration stubbptato2023-10-251-5/+3
|
* WindowAttributes: refactorbptato2023-10-191-1/+1
| | | | | | * rename module (window -> winattrs, to avoid conflict with env/window) * do not use result * remove unused cell_ratio
* css: fix list style type presentational hintsbptato2023-10-141-17/+20
| | | | third time's the charm
* css: support more list types, fix <ul/ol type=...bptato2023-10-142-9/+39
| | | | | | | Turns out you can't just throw the value into the CSS value parser. (Also, correction for the previous commit message: it is not LI but UL or OL.)
* css: support alphabetic list types, support <LI TYPE=...bptato2023-10-142-2/+59
|
* css: change type of rvalue to char (from Rune)bptato2023-10-014-52/+62
| | | | | | | | We did were not using it as a unicode value anywhere, it was just making our life harder. If we ever need unicode delimiter tokens, we can re-introduce them as a different token type.
* selectorparser: fix missing case insensitivitybptato2023-10-011-10/+16
|
* Use twtstr.join everywherebptato2023-10-011-1/+2
|
* Get rid of unicode.toLowerbptato2023-10-012-4/+5
| | | | | It was used by mistake in a hundred percent of the cases we were using it.
* px: convert to float first for percentage valuesbptato2023-09-201-1/+1
| | | | | | | | | px now converts to float64 before converting back to a layout unit when calculating percentage values. This should reduce overflow crashes somewhat. (The real solution would be to not crash on overflow, but that's a little more difficult problem to solve.)
* update chamebptato2023-09-191-0/+1
| | | | and with that, resolve the unknown input type issue
* move around more modulesbptato2023-09-144-5/+5
| | | | | | | | | | * ips -> io/ * loader related stuff -> loader/ * tempfile -> extern/ * buffer, forkserver -> server/ * lineedit, window -> display/ * cell -> types/ * opt -> types/
* twtstr: simplifybptato2023-09-131-2/+3
| | | | | | * remove unused function isAlphaAscii * swap pushHex for less casting * remove == overload for char/rune (we did not really use it anyway)
* color: fix parseLegacyColor bugsbptato2023-09-131-6/+10
| | | | | | * lower-case the input string. * do not fall back to black on error. (i.e. remove the special cased parseLegacyColor0 in cascade)
* refactor: Result[T, DOMException] -> DOMResult[T]bptato2023-08-281-9/+6
|
* javascript: refactorbptato2023-08-281-1/+1
| | | | | | | Split out parts of the JS module, because it was starting to confuse the compiler a little. (Peakmem is back at 750M. Interesting.)
* config: allow modification through JSbptato2023-08-271-9/+12
| | | | | | | This used to be possible until I moved everything under separate headers to their respective objects. Now it works again, mostly; modification of some attributes is still missing.
* Move HTML parsing into Chamebptato2023-08-155-5/+10
