* term: improve damage tracking, special case yaftbptato2024-09-132-15/+42
| | | | | | | It still sucks, but at least now it flashes a bit less. (I should really redo it properly some time) Also, special case yaft so that we always output sixels for it.
* sixel: do not reserve palette entry for transparencybptato2024-09-121-4/+4
| | | | | | | | | Turns out this isn't actually needed. Which makes sense, as transparency doesn't have a color register at all - it's just the default state of pixels. Also, skip octree-based quantization with palette <= 2; unsurprisingly, monochrome gives much better results.
* config: add display.sixel-colorsbptato2024-09-101-0/+3
|
* pager: fix saveSourcebptato2024-09-102-5/+9
| | | | | | Welp. The fence was needed after all. The keybinding was broken anyway; fix that too.
* pager: fix rewrite-url weirdnessbptato2024-09-102-8/+4
| | | | | | | | | saveSource's URL overriding mechanism conflicted with rewrite-url, since the latter wouldn't change the overriding URL (which was not optional either). Remove the former since a) it's just cosmetic and b) not really visible to the user at all.
* pager, term: fix kitty display, add a sixel bounds checkbptato2024-09-092-4/+5
|
* utils: add twtunibptato2024-09-084-177/+175
| | | | | | | | | | | | | | | | | | | std/unicode has the following issues: * Rune is an int32, which implies overflow checking. Also, it is distinct, so you have to convert it manually to do arithmetic. * QJS libunicode and Chagashi work with uint32, interfacing with these required pointless type conversions. * fastRuneAt is a template, meaning it's pasted into every call site. Also, it decodes to UCS-4, so it generates two branches that aren't even used. Overall this lead to quite some code bloat. * fastRuneAt and lastRune have frustratingly different interfaces. Writing code to handle both cases is error prone. * On older Nim versions which we still support, std/unicode takes strings, not openArray[char]'s. Replace it with "twtuni", which includes some improved versions of the few procedures from std/unicode that we actually use.
* term: support SyncTERMbptato2024-09-061-55/+69
| | | | Now it mostly works, provided you set a compatible encoding.
* term: sixel sizing & output fixesbptato2024-09-052-13/+22
| | | | | | | | | | | | * round down to number divisible by 6 for height * make pager's dispw match term's dispw even after width clamping * make *BE procs actually emit/consume big-endian (lol) * fix borked sixel set raster attributes & control string I mixed up SRA with the device control string's parameters, so instead of toggling transparency in the DCS, I was setting the second SRA parameter to 0. Which, by the way, defines the aspect ratio's denominator, and has nothing to do with transparency. Whoops.
* term: add outputSixelImage bounds checksbptato2024-09-041-3/+12
| | | | Makes it so we don't crash the entire browser upon encoding failure.
* loader, client, buffer: use selectInto (not select)bptato2024-09-031-4/+6
| | | | select allocates. (makes sense, but I never realized...)
* loader: fix some fd leaksbptato2024-09-021-4/+2
| | | | + be a bit more paranoid about double closes
* pager: fix missing gotoLine return valuebptato2024-09-011-0/+1
|
* canvas: move to separate CGI scriptbptato2024-09-013-53/+46
| | | | | | | | | | * stream: and passFd is now client-based, and accessible for buffers * Bitmap's width & height is now int, not uint64 * no more non-network Bitmap special case in the pager for canvas I just shoehorned it into the static image model, so it still doesn't render changes after page load. But at least now it doesn't crash the browser.
* term, sixel: misc image fixes, sixel optimizationbptato2024-08-301-15/+24
| | | | | | | | * expand allowed color range somewhat * update maximum sixel size on window resize * fix kitty image cropping * use faster algorithm for sixel compression (also produces less wasteful output)
* sixel: minor optimizationsbptato2024-08-281-1/+3
| | | | | | * don't emit transparency request when we don't need it * add lookup table for missing hash entries * write(2)'ize
* sixel, term: fix off-by-1's in croppingbptato2024-08-281-50/+36
| | | | & clean up outputSixelImage in general
* term: fix crash on identical stacked imagesbptato2024-08-271-1/+3
| | | | | | | in fact, we consider these to be the same image, and arguably that's a bug in and of itself. but at least we don't crash anymore. (also, update todo)
* pager: fix nav direction after view sourcebptato2024-08-271-0/+1
|
* sixel: break out into a separate cgi scriptbptato2024-08-243-132/+150
| | | | | | | | This caches sixel output. Works best when the line height is a multiple of 6px, but should still be faster than the previous solution everywhere else too (simply by virtue of encoding separate images in parallel). Next step: actual color quantization
* winattrs: un-snakeifybptato2024-08-233-6/+6
|
* term: don't panic if termcap tgetent failsbptato2024-08-171-76/+89
| | | | | | | | If TERM is unrecognized by termcap, retry as dosansi. When that fails, just fall back to the non-termcap code path. (There is no reason to panic without termcap; it's just one of the several capability detection mechanisms we use.)
* dom, xhr: slight progress on modules, fix an XHR bugbptato2024-08-151-6/+1
| | | | | | * actually download & compile modules (but don't run them yet) * fix a bug in XHR (on some older Nim versions, move() doesn't actually move)
* xhr: more progressbptato2024-08-151-6/+5
| | | | | | | | | | * add responseText, response * add net tests -> currently sync XHR only; should find a way to do async tests... * update monoucha -> simplified & updated some related code that no longer worked properly
* mailcap: various fixesbptato2024-08-111-5/+5
| | | | | | * parse last line even if it doesn't end with LF * parse flags & named fields case-insensitively * update naming
* dom: remove generic JS bindingsbptato2024-08-113-26/+31
| | | | Dispatch manually with fromJS instead.
* pager: fix incorrect error message in rewrite-urlbptato2024-08-101-3/+6
| | | | It did not actually break rewrite-url, but was still annoying.
* pager: fix <select> drawing after container redrawbptato2024-08-092-1/+3
|
* Update monouchabptato2024-08-093-37/+41
|
* cssvalues, color: use parseEnumNoCase morebptato2024-08-031-2/+4
|
* console, client: optimize console.log (etc.)bptato2024-07-301-2/+2
| | | | use JSValue varargs instead
* term: constify queriesbptato2024-07-301-3/+15
| | | | | + also send register & image dimension queries in forced sixel mode, and image dimension query on window resize
* Fixes for Nim 2.2bptato2024-07-294-9/+1
| | | | | | | | | * xmlhttprequest: fix missing import * painter: generic tuple workaround * dynstream: merge module with implementations (so it will work with vtables) Not enabling vtables yet since it doesn't work with refc.
* buffer, pager, config: add meta-refresh + misc fixesbptato2024-07-284-32/+91
| | | | | | | | | * buffer, pager, config: add meta-refresh value, which makes it possible to follow http-equiv=refresh META tags. * config: clean up redundant format mode parser * timeout: accept varargs for params to pass on to functions * pager: add "options" dict to JS gotoURL * twtstr: remove redundant startsWithNoCase
* client, sandbox: fix termux buildbptato2024-07-241-5/+8
| | | | | Still not perfect, because it crashes on missing /tmp dir so you have to manually set it...
* pager: fix dead containers left in replaceBackupbptato2024-07-232-0/+9
| | | | | | | | | | | 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
* term: fix positionImage sixel size clamping (take 2)bptato2024-07-231-2/+2
| | | | | | Hope I got it right this time. (The previous iteration did not take into account the image position on the screen, so it was just as bad as the first one.)
* term: fix positionImage sixel size clampingbptato2024-07-231-6/+10
| | | | | clamping maxwpx/maxhpx crops the image starting from the canvas corner, not the image corner
* term: fix kitty image positioningbptato2024-07-201-2/+5
| | | | only use sixelMaxWidth/sixelMaxHeight for sixel
* loader: copy cached items on buffer cloningbptato2024-07-203-4/+8
| | | | | This fixes a bug where cloning buffers with images would crash the browser.
* loader: async status/headers for fetchbptato2024-07-191-7/+2
| | | | | | | | The status code & headers are no longer guaranteed to be sent right after res/outputId, so read them asynchronously instead. (This is pretty much the same code as the buffer connection handler in pager. Hopefully we can merge the two at some point.)
* client: remove redundant global functionsbptato2024-07-161-22/+0
| | | | these are already defined on Window
* timeout: simplify, misc fixesbptato2024-07-161-7/+7
| | | | | | Merge timeout & interval code paths. This fixes clearTimeout not clearing intervals.
* term: image sizing fixesbptato2024-07-161-8/+39
| | | | | | * add sixel max width/height query * add cell size query (it's more accurate than dividing window size when you change xterm font size)
* config: support smart casebptato2024-07-161-4/+1
| | | | and enable it by default.
* 32-bit compilation fixesbptato2024-07-132-9/+9
| | | | | | | | It seems registerHandle/unregister doesn't accept cint as handles. Not sure why it even works on 64-bit targets... (maybe some converter weirdness?) Seems best to explicitly cast it away.
* timeout: fix jsvalue leakbptato2024-07-101-0/+1
|
* lineedit: small cleanupbptato2024-07-071-4/+1
|
* pager: fix redirection to deleted buffersbptato2024-07-062-5/+19
| | | | | | 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.
* main, forkserver: optimize startupbptato2024-07-061-9/+2
| | | | | Merge "load config" with "fork loader", so that the loader process gets forked one packet earlier.
