* pager: fix dead containers left in replaceBackupbptato2024-07-231-0/+3
| | | | | | | | | | | fixes the following bug: * click a link that redirects somewhere * go back * discard buffer (that had the link) * discard the new buffer then you would find yourself in a zombie buffer you previously discarded
* loader: copy cached items on buffer cloningbptato2024-07-201-0/+3
| | | | | This fixes a bug where cloning buffers with images would crash the browser.
* pager: fix redirection to deleted buffersbptato2024-07-061-0/+1
| | | | | | Fixes the bug where getting redirected to a buffer that the pager then deleted (e.g. image display, site no longer available, etc.) would land you in a buffer detached from the main tree.
* pager: PNGify kitty images, clear images on buffer switchbptato2024-07-021-0/+2
| | | | | | | | | | | Saves bandwidth; it's especially useful over SSH. Still not sure if this is the right solution, since it now needs two select cycles instead of one, and it does yet another copy of the image. (Unnecessarily, because stbi cannot stream its output, and stbiw cannot stream its input.) Also, to save memory, we now discard decoded images of buffers that are not being viewed.
* promise, container: fix nil derefsbptato2024-06-301-1/+3
|
* dom, pager: cache images from networkbptato2024-06-291-4/+8
| | | | | | | | | | | With many limitations: * slightly randomized expiry, so it's harder to fingerprint * only images. so e.g. CSS is still left uncached * it's per-buffer and non-persistent, so images are still redownloaded for every new page load so it's more of an image sharing between placements than true caching.

* pager: refactor drawing codebptato2024-06-221-50/+344
| | | | | | | * merge select into container * avoid unnecessary redraws in draw() for parts of the screen that haven't been updated * various image redraw fixes
* term, pager: improve image displaybptato2024-06-211-5/+9
| | | | | | * basic repaint algorithm for sixel (instead of brute force "clear the whole screen") * do not re-send kitty images already on the screen

* img, loader: separate out png codec into cgi, misc improvementsbptato2024-06-201-0/+8
| | | | | | | | | | | | | | | * multi-processed and sandboxed PNG decoding & encoding (through local CGI) * improved request body passing (including support for output id as response body) * simplified & faster blob()/text() - now every request starts suspended, and OngoingData.buf has been replaced with loader's buffering capability * image caching: we no longer pull bitmaps from the container after every single getLines call Next steps: replace our bespoke PNG decoder with something more usable, add other decoders, and make them stream.
* buffer: add autofocusbptato2024-06-081-22/+25

* buffer: fix multipart formsbptato2024-05-111-17/+23
| | | | | | | | | * fix enctype not getting picked up * fix form data constructor requiring open() syscall (which gets blocked by our seccomp filter) * add closing boundary to multipart end * pass fds instead of path names through WebFile/Blob and send those through bufwriter/bufreader
* luwrap: use separate context (+ various cleanups)bptato2024-05-101-57/+41
| | | | | | Use a LUContext to only load required CharRanges once per pager. Also, add kana & hangul vi word break categories for convenience.
* luwrap: replace Nim unicode maps with libunicodebptato2024-05-091-2/+4
| | | | | | | | | | | | | | | | | Instead of using the built-in (and outdated, and buggy) tables, we now use libunicode from QJS. This shaves some bytes off the executable, though far less than I had imagined it would. Also, a surprising effect of this change: because libunicode's tables aren't glitched out, kanji properly gets classified as alpha. I found this greatly annoying because `w' in Japanese text would now jump through whole sentences. As a band-aid solution I added an extra Han category, but I wish we had a more robust solution that could differentiate between *all* scripts. TODO: I suspect that separately loading the tables for every rune in breaksViWordCat is rather inefficient. Using some context object (at least per operation) would probably be beneficial.
* js: refactorbptato2024-05-081-1/+1
| | | | | | | * prefix to-be-separated modules with js * remove dynstreams dependency * untangle from EmptyPromise * move typeptr into tojs
* Use isSome instead of isOkbptato2024-05-051-1/+1
| | | | no point in having identical overloads
* buffer: add toggleImagesbptato2024-04-271-0/+9

* Initial image supportbptato2024-04-251-4/+5
| | | | | | | | | | | | | | | | | * png: add missing filters, various decoder fixes * term: fix kitty response interpretation, add support for kitty image detection * buffer, pager: initial image display support Emphasis on "initial"; it only "works" with kitty output and PNG input. Also, it's excruciatingly slow, and repaints images way too often. Left undocumented intentionally it for now, until it actually becomes useful. In the meantime, adventurous users can find out themselves why: [[siteconf]] url = "https://.*" images = true
* sandbox: seccomp support on Linuxbptato2024-04-181-5/+21
| | | | | | | | | | | | | | | | | We use libseccomp, which is now a semi-mandatory dependency on Linux. (You can still build without it, but only if you pass a scary long flag to make.) For this to work I had to disable getTimezoneOffset, which would otherwise call localtime_r which in turn reads in some files from /usr/share/zoneinfo. To allow this we would have to give unrestricted openat(2) access to buffer processes, which is unacceptable. (Giving websites access to the local timezone is a fingerprinting vector so if this ever gets fixed then it should be an opt-in config setting.) This patch also includes misc fixes to buffer cloning, and fixes the LIBEXECDIR override in the makefile so that it is actually useful.
* Update code stylebptato2024-04-171-89/+92
| | | | | | * separate params with ; (semicolon) instead of , (colon) * reduce screaming snake case use * wrap long lines
* 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 heightbptato2024-03-301-0/+4

* container: rename enumsbptato2024-03-271-17/+17

* buffer: fix cancel()bptato2024-03-271-10/+17
| | | | | | | | | | * 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
* io: derive DynStream from RootObj (not Stream)bptato2024-03-241-4/+4
| | | | | | | | 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.)
* buffer: send title during load + other title stuffbptato2024-03-211-12/+13
| | | | | | | * send title to pager as soon as it's available * expose `title' to DOM * rename undocumented `getTitle' js function to `title' getter in Container
* buffer: also buffer input readsbptato2024-03-211-3/+1
| | | | this is buffer reading from pager
* pager: add "save link", "save source"; change & document some keybindingsbptato2024-03-201-23/+43
| | | | | | | | | * `s{Enter}' now saves link, and `sS' saves source. * Changed ;, +, @ to g0, g$, gc so that it's somewhat consistent with vim (and won't conflict with ; for "repeat jump to char") * Changed (, ) to -, + so that it doesn't conflict with vi's "previous/next sentence" (once we have it...) * Add previously missing keybindings to about:chawan
* buffer: add markURLbptato2024-03-191-2/+12
| | | | Useful when browsing plaintext files; w3m has it too.
* client: fix "Hit any key" bug on load failurebptato2024-03-171-5/+8
| | | | it's an unintended side effect that we do not want
* container: fall back to text/plain instead of application/octet-streambptato2024-03-161-1/+2
| | | | | | | | | | | | | This has its own problems, but application/octet-stream has the horrible consequence that opening any local file with an unrecognized type automatically quits the browser. (FWIW, w3m also falls back to text/plain, so it's not such an unreasonable default.) The proper solution would be to a) fix the bug that makes the browser auto-quit and b) show a "what to do" prompt for unrecognized file types (and allow users to override it, preferably on a per-protocol basis.)
* container: cursor x fixesbptato2024-03-151-2/+4
| | | | | | * also set fromX to corrected target x if target x is less than corrected x; this is mainly so that setCursorX(-1) works as expected * return w from cursorFirstX() even if cursorx is <= the last character
* Clean up BufferConfigbptato2024-03-151-11/+14
| | | | | | | | It was defined in the wrong module, and unnecessarily included LoaderClientConfig. Also, referrerPolicy was not being propagated to loader clients because it was (incorrectly) in BufferConfig instead of LoaderClientConfig.
* pager: unregister containers properly when headers are pendingbptato2024-03-141-1/+2
| | | | | It can happen that a container is deleted before it acquires a buffer process; add it to the `unreg' array in this case too.
* Move around some modulesbptato2024-03-141-1/+1
| | | | | | | | * extern -> gone, runproc absorbed by pager, others moved into io/ * display -> local/ (where else would we display?) * xhr -> html/ * move out WindowAttributes from term, so we don't depend on local from server
* pager: add "open in editor" keybinding (sE)bptato2024-03-141-2/+4
| | | | | | only for source for now, rendered document is a bit more complicated (also, get rid of useless extern/editor module)
* client: fix blocking reads on container connectionbptato2024-03-121-1/+0
| | | | | | | | | | | | | | | | Sometimes, headers take a while to reach us even after the result has been sent. e.g. echo 'Cha-Control: Connected' sleep 5 echo 'Cha-Control: ControlDone' ^ this froze the UI for 5 seconds, that's certainly not what we want. Since we don't have a proper buffered reader yet, and I don't want to write another disgusting hack like BufStream, we just use a state machine to figure out how much we can read. Sounds bad, but in practice it works just fine since loader's response patterns are very simple.
* loader: remove applyHeadersbptato2024-03-121-11/+8
| | | | | | | Better compute the values we need on-demand at the call sites; this way, we can pass through content type attributes to mailcap too. (Also, remove a bug where applyResponse was called twice.)
