* term: improve pixels-per-column/line detectionbptato2024-02-251-1/+1
| | | | | | | | | Some terminal emulators (AKA vte) refuse to set ws_xpixel and ws_ypixel in the TIOCGWINSZ ioctl, so we now query for CSI 14 t as well. (Also CSI 18 t for good measure, just in case we can't ioctl for some reason.) Also added some fallback (optionally forced) config values for width, height, ppc, and ppl. (This is especially useful in dump mode.)
* css: always use defaultColor as the initial colorbptato2024-02-251-7/+4
| | | | | | | | | | This way, we do not end up with ugly contrast-corrected white on terminals with arbitrary backgrounds by default. (Now we get the native -cha-ansi(default) instead). (We leave background-color as transparent; this should have the same effect, since defaultColor as bgcolor is ignored, but makes more sense (and will allow us to un-ignore defaultColor as bgcolor in the future.))
* 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.
* dom: enumize attribute namesbptato2024-02-083-23/+30

* dom: atomize id, name, DOMTokenListbptato2024-02-082-67/+90

* 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.)
