* remove dead code, fix openArray casingbptato2024-04-083-7/+4

* css, layout: flexbox fixesbptato2024-04-062-8/+31
| | | | | | | * do not re-resolve FlexPendingItem sizes; it's pointless and it breaks percentage sizes * fix some bugs in `flex' shorthand parsing * add `flex-flow' shorthand

* Initial flexbox supportbptato2024-04-052-163/+537
| | | | | | | | | Still far from being fully standards-compliant, or even complete, but it seems to work slightly less horribly than having no flexbox support at all on sites that do use it. (Also includes various refactorings in layout to make it possible at all to add flexbox.)
* sandbox: add OpenBSD pledge/unveil supportbptato2024-04-034-8/+39
| | | | | | | | | | | | pledge is a bit more fine-grained than Capsicum's capability mode, so the buffer & http ("network") sandboxes are now split up into two parts. I applied the same hack as in FreeBSD for overriding the buffer selector kqueue, because a) I didn't want to request sysctl promise b) I'm not sure if it would even work and c) if it breaks on OpenBSD, then it's broken on FreeBSD too, so there's a greater chance of discovering the bug.
* loader: constant time key comparisonbptato2024-04-021-1/+13
| | | | | GCC seems to generate something that strongly resembles a constant time comparison, so I guess this should be good enough.
* pager: fix incremental search with empty stringbptato2024-03-301-3/+11
| | | | | | | | | | | | | | This is broken in w3m too, so we take nvi behavior instead. Also, we now consistently complain when the user tries to search for an empty string instead of just occasionally spitting out "invalid regex" alerts. (In w3m, /search^M/^M just jumps to the first search result with ISEARCH. In nvi, it jumps to the second one with both searchincr on and off. w3m only produces the latter behavior with regular search, which is I assume why I made it work this way, but it's still inconsistent for no good reason.)
* pager: fix weird halfPage* behaviorbptato2024-03-301-6/+6
| | | | | | | | | For some reason, halfPageDown decremented height instead of incrementing it, which caused some rather weird behavior where halfPageUp + halfPageDown would put the cursor in a different position than it was before. Also, we must increment *before* dividing to mimic vi behavior properly.
* pager: exclude status line from buffer heightbptato2024-03-302-1/+9

* layout: add missing min/max heights to absolute sizesbptato2024-03-301-1/+3
|
* layout: fix various table cell sizing bugsbptato2024-03-301-47/+35
| | | | | | | | | | It seems I never properly converted the table cell (pre-)sizing code to use SizeConstraints, so it was still in a half-working state where it broke down e.g. on nested tables. * move auto check to canpx * simplify convoluted and broken table cell size calculation into something that actually works
* pager: edit source fixesbptato2024-03-302-71/+56
| | | | | | | * URI-decode path name for local files in default config * (ab)use mailcap command quoting for passing params to editor command instead of replicating it badly in formatEditorName * rename mailcap enums
* layout: fix float positioning with marginsbptato2024-03-301-1/+1
| | | | | | | | | | | | | | | Here we are restricting the float to the same width constraint as its parent, so we must add offset.x both when the float is larger than this constraint *and* when the float fits into the constraint. An example of what this fixes: <div style="padding-left: 10em; background: green"> <div style="float: right; background: red"> wat ^ previously the float was positioned as if the padding had been on the *right*, because it did not take into account offset.x.
* buffer: fix markURL in plaintextbptato2024-03-291-3/+31
| | | | | | | We must HTML escape data, or the fragment parser will parse plain text as markup. (However, just running htmlEscape() on data is not enough; that would also mark <, ', etc. as &gt, &apos. So we only escape after the regex is executed.)
* term: flush stdout in anyKeybptato2024-03-291-0/+1

* pager: fix broken writeToFilebptato2024-03-292-5/+4

* ansi2html: support passing titlesbptato2024-03-292-17/+22
| | | | | | | Use content type attributes so e.g. git.cgi can set the title even with a text/x-ansi content type. (This commit also fixes some bugs in content type attribute handling.)
* fflush() before forksbptato2024-03-283-6/+19
| | | | | seems like a good idea, especially because CGI uses stdout as the IPC mechanism
* Add capsicum supportbptato2024-03-2811-38/+169
| | | | | | | | | | | | | It's the sandboxing system of FreeBSD. Quite pleasant to work with. (Just trying to figure out the basics with this one before tackling the abomination that is seccomp.) Indeed, the only non-trivial part was getting newSelector to work with Capsicum. Long story short it doesn't, so we use an ugly pointer cast + assignment. But even that is stdlib's "fault", not Capsicum's. This also gets rid of that ugly SocketPath global.
* term: improve color detectionbptato2024-03-271-5/+16
| | | | | some terminals (alacritty) don't support XTGETTCAP and don't even respond with ANSI color support to DA1, so just fall back to termcap.
* container: rename enumsbptato2024-03-271-17/+17

* buffer: fix cancel()bptato2024-03-274-23/+54
| | | | | | | | | | * fix mismatch between return value & read value that would either crash or freeze the browser depending on its mood * add an assertion to detect the above footgun * fix some resource leaks * fix iteration over a table that called a function which altered the table in buffer's cancel() * if user cancels before anything is loaded, destroy the container too
* layout: fix another infinite loopbptato2024-03-261-2/+2
| | | | | | | aaaaa (this was even worse than the previous one, of course caused by the fix...)
* config: improve input systembptato2024-03-264-15/+112
| | | | as described in <https://todo.sr.ht/~bptato/chawan/6>
* config, toml: rename enumsbptato2024-03-263-114/+114

* layout: avoid infinite loop in line wrappingbptato2024-03-261-11/+10
| | | | it would get into an infinite loop with line-height: 0 and floats
* layout: also round line height for painting backgroundsbptato2024-03-261-3/+2
| | | | | it's pointless to do otherwise, and results in inconsistencies between line positioning and background coloring.
* layout: ensure lines are not higher than they must bebptato2024-03-262-11/+17
| | | | | | This is still a more conservative approach than completely disabling line-height. It seems to work better than preserving rounded line-height in all cases, anyway.
* layout: optimize inline background areasbptato2024-03-261-18/+51
| | | | | | | Instead of adding a new area for every single line, extend already existing areas when possible. (This was my original plan but I got lazy.)
* pager: percent-decode path name in askDownloadPathbptato2024-03-251-1/+1
|
* layout: rework inline box area modelbptato2024-03-253-154/+180
| | | | | | | | | | | | | Specifying the background area as three LayoutUnit pairs sounds clever, but breaks down for text-align: center. * store line Y offset in LineBox - this is necessary to pass down areas we need to paint * refactor addHorizontalLine loop; remove mystery "If necessary, update ictx's width" line that used to be labeled "TODO this seems meaningless" and indeed seems meaningless now (I am prepared to deeply regret this later) * replace broken & convoluted startOffset/endOffset/size with a simple seq of offsets + sizes

* js: proper distinction between Opt/Optionbptato2024-03-2411-118/+110
| | | | | | | | | | | | | | | | until now, this had very strange (and inconsistent) semantics: * err() was used for exception propagation, but also as a null value * Option accepted undefined as a none value, but not null * Opt and Option were used interchangeably (and mostly randomly) Now, Result is always used for error reporting, and err(nil) means JS_EXCEPTION. (Opt is a special case of Result where we don't care about the error type, and is not used in JS.) Option on the other hand means "nullable variation of normally non-nullable type", and translates to JS_NULL. In JS we mainly use it for turning strings nullable.

* cgi: reset SIGCHLD handler in childrenbptato2024-03-241-0/+4
| | | | this was causing problems in git.cgi
* io: derive DynStream from RootObj (not Stream)bptato2024-03-2422-534/+291
| | | | | | | | This way they are no longer compatible, but we no longer need them to be compatible anyway. (This also forces us to throw out the old serialize module, and use packet writers everywhere.)
* pager: detect JS as textbptato2024-03-241-1/+5
| | | | | hack so it's possible to view JS code in a buffer even if it's set as e.g. application/javascript in user mime.types
* bufreader: add initPacketReaderbptato2024-03-243-7/+14

* buffer: form fixes & improvementsbptato2024-03-245-86/+130
| | | | | | | * fall back to text for unimplemented input types * add custom prompt to all text-like input types * show min/max for range * fix accidental override of repaint
* io: add bufreaderbptato2024-03-2110-261/+426
| | | | analogous to bufwriter
* config: add default-headers to siteconfbptato2024-03-214-47/+32
| | | | | | | So long as we have to live with siteconf, let's at least make it useful. Also, rewrite the header overriding logic because while it did work, it only did so accidentally.
