* config: resolve download-dir as path, update docsbptato2024-11-131-1/+3
| | | | | | | Turns out it's more useful to have env vars in the variable than to allow incomplete path names. Also, fix the disappearing backslash issue in docs.
* container: fix `U' cursor repositioning (really)bptato2024-11-122-25/+16
| | | | I swear this feature is cursed
* buffer: fix broken gotoAnchor behaviorbptato2024-11-122-44/+44
| | | | | | | | | | | | | | | | | 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).

| | | | | stopgap measure until I think of a more flexible mouse configuration method
* cascade: adjust prefers-color-scheme based on terminal backgroundbptato2024-11-101-0/+1
| | | | also, default link color is now blue for light terminal backgrounds
* layout -> cssbptato2024-11-102-3/+3
| | | | as much as I wish it weren't, layout *is* css.

* config: refactor, accept more possible config dirsbptato2024-10-281-1/+2
| | | | | | | | | | | | | | | | | | | | | I'm starting to favor dotfiles over XDG basedirs, but there's no reason why we couldn't have both. So now the search path is: 0. if config was set through -C, use that 1. $CHA_CONFIG_DIR is set -> $CHA_CONFIG_DIR/config.toml 2. $XDG_CONFIG_HOME is set -> $XDG_CONFIG_HOME/chawan/config.toml 3. ~/.config/chawan/config.toml exists -> use that 4. ~/.chawan/config.toml exists -> use that Notably, this makes it so the default directory is ~/.chawan *if* you don't have an existing config.toml file. So in that case known_hosts will be placed in ~/.chawan/known_hosts. However, configurations with a config in ~/.config/chawan/config.toml continue to work as expected, as for those the known_hosts file remains inside ~/.config/chawan/. Finally, I've added a default user CGI directory to reduce friction in setting CGI up. (Like known_hosts, it's also relative to whatever config dir you have.)
* pager: misc extern fixesbptato2024-10-271-80/+109
| | | | | * fix externFilterSource ignoring content types other than html * refactor runProcess to use a custom fork/exec instead of system(3)
* container: fix crash on isearch between redirectsbptato2024-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | Sadly, pushCursorPos may not be paired with a popCursorPos in case the container in question is replaced during the isearch. The easiest way to reproduce this is: * start request to a page that redirects * start isearch * redirection happens, now the old container is gone * type something Then, popCursorPos would try to pop the cursor position from the new container. An alternative (and better) solution would be to add a weak ref to the container as the line edit data. Sadly, we don't have weak refs, and I don't want to hack them in with finalizers. (But maybe I should. Hmm.)
* termcap: merge into termbptato2024-10-231-1/+29
| | | | | again, not that useful to put it in a separate module if only term uses it
* dynstream: refactorbptato2024-10-203-9/+7
| | | | | | | | | | * consistently use cint instead of FileHandle - this was another remnant of winapi support; on posix, they are the same. * move "blocking" field to PosixStream * recvFileHandle -> recvFd, sendFileHandle -> sendFd * merge serversocket into dynstream * merge auxiliary C functions into dynstream_aux
* dynstream, serversocket: use posix instead of nativesocketsbptato2024-10-203-6/+2
| | | | | | | | | | | nativesockets is a wrapper over posix and winapi, but we don't support winapi, so we can just fall back to PosixStream instead. SocketStream remains as a constraint over PosixStream to allow sendFileHandle/recvFileHandle. As a nice side effect, we can drop some allowed syscalls from the seccomp filter.
* pager: refactor mailcap, console; misc fixesbptato2024-10-142-245/+227
| | | | | | | | | * use more PosixStream (because it has double-close checking) * factor out some common mailcap operations * move console from client to pager * fix case-insensitive mime type matching * replace convoluted fdin/fdout comparison logic (that only accidentally worked) with a boolean flag
* twtstr, toml: misc cleanupbptato2024-10-131-2/+1
| | | | | * remove unused DateTime toml type * add parseIntP for pointer-size int parsing
* base64: merge into twtstr/envbptato2024-10-131-1/+0

* layout, pager: preserve tabs on display, selection & outputbptato2024-10-102-23/+45
| | | | | | | | | | | | Substitute tabs with one of eight PUA characters based on their width, and convert them back in the pager: * TUI mode always prints spaces, but now handles tabs appropriately on cursor movement * dump mode tries to preserve hard tabs, but uses soft tabs when that is not possible (e.g. tabs after a margin, tab with background color, etc) * selection mode always outputs hard tabs.
* client: fix redirected buffers jumping back to parent on reloadbptato2024-10-071-0/+5
| | | | | replaceBackup was not being cleared, so the next gotoURL with a replace pointing to such buffers wouldn't work.
* pager: do not choke on empty editor commandbptato2024-10-071-2/+4
|
* color: reduce CellColor size, misc color refactoringbptato2024-10-062-15/+26
| | | | | | * split out CSSColor from CellColor; now CellColor is just 4 bytes (which helps reduce FormatCell size) * unify color function naming (still not perfect)
* pager: add missing int conversionbptato2024-10-061-1/+1

* Update Chagashibptato2024-10-051-9/+0

* dynstream: fix memory leakbptato2024-10-041-2/+1
| | | | now I know why overloading dealloc felt wrong
* sixel, term: reduce half-dump special casingbptato2024-10-043-22/+37
| | | | | | | Makes it slightly easier to debug image output. Also, we stop sending dimension headers, and no longer check for the scheme env var to make CLI invocation a bit less annoying.
* sixel: transparency improvementsbptato2024-10-031-4/+4
| | | | | | | * don't set transparency when raster attributes suffice - it seems terminals don't background-fill in that case either. * fix transparency in encoder standalone mode * update comments
* term: "fix" GNU screen not respecting query sequence orderbptato2024-10-011-9/+22
| | | | | | | | | | | | | wtf ... OK, it's a "fix" as much as you can fix this. I'm not adding a timer just to work around screen silently reordering my output. (Who thought this would be a good idea??) Unfortunately, this means that your background/foreground colors won't get detected when using screen. Not that they would have been until now.
* pager: improve rewrite-url semanticsbptato2024-09-301-7/+19
| | | | | | | | | | | | | Previously, it just changed the URL before loading the site; now it's an actual redirect. Technically, the previous behavior was more flexible, because it let you apply siteconf rules exclusively for sites where you redirected from. Practically, this was not very useful, and probably unexpected for anybody trying to use the feature. This also fixes a bug where the loader filter would be set for the original page, so you couldn't switch from https to http, etc.
* timeout: accept err stream as parambptato2024-09-301-6/+3
| | | | | gets rid of a todo. (not sure why I thought this was important, but it sure looks nicer)
* pager: add missing nil checkbptato2024-09-291-2/+3
|
* loader: send headers for tocache requests toobptato2024-09-282-6/+3
| | | | | This lets us send the transparency bit as a header, and also halves the number of header parsers in loader.
* container: fix control char displaybptato2024-09-284-28/+23
| | | | | | Also, kill twidth and its friends; we haven't been using it for a while now. (In the future, a solution with PUA chars might be worth exploring.)
* container: don't show hover type on ubptato2024-09-271-1/+1
| | | | it's a waste of space, and doesn't work well with showFullAlert
* loader, pager: fix fd leaksbptato2024-09-251-0/+3

* pager: make image ordering deterministicbptato2024-09-252-4/+6
| | | | ensure that images are shown in the order buffer sent them
* sixel: support transparencybptato2024-09-243-19/+29
| | | | | | | | | | | | | | | | | | Sixel can only represent transparency for fully transparent (alpha = 0) and fully opaque (alpha = 255) pixels, i.e. we would have to do blending ourselves to do this "properly". But what do you even blend? Background color? Images? Clearly you can't do text... So instead of going down the blending route, we now just approximate the 8-bit channel with Sixel's 1-bit channel and then patch it up with dither. It does look a bit weird, but it's not *that* bad, especially compared to the previous strategy of "blend with some color which hopefully happens to be the background color" (it rarely was). Note that this requires us to handle transparent images specially in term. That is, for opaque ones, we can leave out the "clear cells affected by image" part, but for transparent ones, we must clear the entire image every time.
* select: use a separate module (again)bptato2024-09-244-351/+374
| | | | | | | | | Now we dispatch to select objects from the pager object too, just to make things even more confusing. Well, it works better than the previous arrangement, in that trying to use unimplemented movements now just throws instead of moving around the container. Yay for OOP (?)
* pager: fix double-width overprint & reload blank screen bugbptato2024-09-242-8/+17
| | | | | * fix overprint of double width chars in status & select * fix blank screen on reload + startpos screen move
* sixel: use inline background for blendingbptato2024-09-242-2/+2
| | | | still not really great, because inline background is a mess too
* Replace std/selectors with pollbptato2024-09-232-63/+78
| | | | | | | | | | | | std/selectors uses OS-specific selector APIs, which sounds good in theory (faster than poll!), but sucks for portability in practice. Sure, you can fix portability bugs, but who knows how many there are on untested platforms... poll is standard, so if it works on one computer it should work on all other ones. (I hope.) As a bonus, I rewrote the timeout API for poll, which incidentally fixes setTimeout across forks. Also, SIGWINCH should now work on all platforms (as we self-pipe instead of signalfd/kqueue magic).
* client, forkserver, dynstream: misc refactorings, fixesbptato2024-09-232-86/+84
| | | | | | * fix broken int conversion in dynstream * fix EPIPE handling in forkserver * merge fdmap and connectingContainers into loader map
* term: refactorbptato2024-09-232-145/+157
| | | | | * reduce copies & allocations * simplify SGR generation
* loader: mmap intermediate image files, misc refactoringbptato2024-09-223-27/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | * refactor parseHeader * optimize response blob() * add direct "to cache" mode for loader requests which sets stdout to a file, and use it for image processing * move image resizing into a separate process * mmap cache files in between processing steps when possible At last, resize is no longer a part of image decoding. Also, it feels much nicer to keep encoded image data in the same cache as everything else. The mmap operations *should* be more efficient than copying the whole RGBA data through a pipe. In practice, it only makes a difference for loading (well, now just mmapping) the encoded image into the pager, where it singlehandedly speeds up image display by 10x on my test image. For the other steps, the unfortunate fact that "tocache" must delay the next fork/exec in the pipeline until the entire image is processed seems to equal out any wins we might have gotten from skipping a single raw RGBA copy. I have tried moving the delay before the exec (it's possible with yet another pipe), but it didn't help much and made the code much uglier. (Not that tocache didn't, but I can live with this...)
