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.)

+ also send register & image dimension queries in forced sixel mode,
and image dimension query on window resize

* 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 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

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.)

clamping maxwpx/maxhpx crops the image starting from the canvas
corner, not the image corner
|
| |
|
|
| |
only use sixelMaxWidth/sixelMaxHeight for sixel
|
| |
|
|
|
|
| |
* add sixel max width/height query
* add cell size query (it's more accurate than dividing window size when
you change xterm font size)
|
| | |
|
| |
|
|
|
| |
* query default ANSI colors with OSC 4
* disable queries overridden by config

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.

x is clamped to 0, so there is no need to offset it by offx.

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.

* merge select into container
* avoid unnecessary redraws in draw() for parts of the screen that
haven't been updated
* various image redraw fixes
|

|

* basic repaint algorithm for sixel (instead of brute force "clear the
whole screen")
* do not re-send kitty images already on the screen
|
| |
|
|
|
|
| |
* preserve alpha in kitty + simplify encoder
* pass unknown image types to stbi (as image/x-unknown) and let it
detect the type

* 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.

* Replaced the `pcanvas' comparison with a much simpler tracking of
the first damaged cell in writeGrid, which is significantly faster.
* Removed emulate-overline: it's of too little utility compared to the
maintenance burden it caused.

* blend bgcolor with cell color
* do not round up to 6
We don't use the sixel transparency feature because it's useless: sixel
transparency (AFAICT) only lets us respect alpha == 0, but we should
either respect *all* alpha, or no alpha at all.
Since we do color blending, we *do* respect all alpha, but only of
background color. This sadly means that text under images gets
destroyed, but at least transparent images don't look like garbage.

Unsigned operations and conversions to unsigned types always wrap/narrow
without checks, so no need to manually mask/cast/etc. them.

* 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
|
| |
|
|
|
|
| |
* separate params with ; (semicolon) instead of , (colon)
* reduce screaming snake case use
* wrap long lines

It is quite straightforward, because XTerm has a functionality to do
just this.
(In fact, it automatically restores the title when I use smcup/rmcup.
But when I don't, it will linger until I close the window or change the
title again.)

some terminals (alacritty) don't support XTGETTCAP and don't even
respond with ANSI color support to DA1, so just fall back to termcap.

* move mouse handling to term
* do not use File for input just to disable buffering anyway
|
| |
|
|
|
|
| |
* do not immediately quit when all containers are gone
* fix double saving bug
* fix wrong "save to" string
|
|
|
* 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
