This is incomplete, and we'll solve the problem differently. For now,
leave colors that are not mentioned in the theme. This causes problems
for sparse themes, but a following commit will fix that by making
"fish_config theme choose" erase all variables set by a previous
invocation (but not erase variables set by the user). Only webconfig
won't do that since it (historically) uses copy semantics, but we
could change that too if needed.
This also breaks the guarantee mentioned by this comment in webconfig:
> Ensure that we have all the color names we know about, so that if the
> user deletes one he can still set it again via the web interface
which should be fine because:
1. a following commit will always set all globals at interactive init,
so colors should only be missing in edge cases ("fish -c fish_config").
2. it's easy to recover from by setting a default theme.
The "fish-" prefix is not needed here and it would add more noise to
a following commit which adds default-{dark,light} variants that use
24 bit RGB colors.
For historical reasons (namely the webconfig origin), our theme
names contain spaces and uppercase letters which can be inconvenient
when using the "fish_config theme choose" shell command. Use more
conventional file names.
Web config still uses the pretty names, using the ubiquitous "# name:"
property.
This function returns a heterogeneous list (containing dicts/lists)
by accident. Fix that and reduce code duplication. Fixes c018bfdb4d
(Initial work to add support for angularjs, 2013-08-17).
These are obsolete as of c8001b5023 (encoding: use UTF-8 everywhere,
2025-10-18). The only place where we still read the user's LC_CTYPE
is in libc::wcwidth(), but that's kind of a regression -- we should
always be using a UTF-8 LC_CTYPE if possible -- which will be fixed
by a following commit.
As mentioned in #11926 our "fish_config" workaround for macOS
10.12.5 or later has been fixed in macOS 10.12.6 according to
https://andrewjaffe.net/blog/2017/05/python_bug_hunt/, I think we
can assume all users have upgraded to that patch version Remove
the workaround.
In particular
- test that it will return an error if the URL is invalid
- that the main page matches the index.html in git
- that "Enter" key will exit

- Windows allows port reuse under certain conditions. In fish_config
case, this allows the signal socket to use the same port as http (e.g.
when using MINGW python). This can cause some browsers to access the
signal socket rather than the http one (e.g. when connecting using
IPv4/"127.0.0.1" instead of IPv6/"::1").
- This is also more efficient since we already know that all ports up to
and including the http one are not available

Ruff's default format is very similar to black's, so there are only a
few changes made to our Python code. They are all contained in this
commit. The primary benefit of this change is that ruff's performance is
about an order of magnitude better, reducing runtime on this repo down
to under 20ms on my machine, compared to over 150ms with black, and even
more if any changes are performed by black.

Underline is no more a boolean and should be one of the accepted style,
or None. By keeping False as default value, web_config was generating
wrong --underline=False settings
Part of #11861
My phone uses dotted underline to indicate errors; that seems nice, a bit
less aggressive than curly. Unfortunately dotted underlines are not as well
supported in terminal emulators; sometimes they are barely visible. So it's
unlikely that we want to use --underline=dotted for an important theme.
Add double and dashed too I guess, even though I don't have a concrete
use case..
Add a new underline-color option to set_color (instead of adding an optional
color argument to --underline); this allows to set the underline color
independently of underline style (line, curly, etc.). I don't think this
flexibility is very important but this approach is probably the least hacky.
Note that there are two variants:
1. \e[58:5:1m
2. \e[58;5;1m
Variant 1 breaks:
breakage from colon-variant for colored underlines
- cool-retro-term makes text blink
- GNU screen (goes into bold mode)
- terminology (goes into bold mode)
Variant 2 would break:
- mintty (Cygwin terminal) -- it enables bold font instead.
- Windows Terminal (where it paints the foreground yellow)
- JetBrains terminals echo the colons instead of consuming them
- putty
- GNU screen (goes into bold mode)
- st
- urxvt
- xterm
- etc.
So choose variant 1.

set_color --underline=curly outputs \e[4:3m which breaks the following
terminals:
- Terminal.app interprets it as yellow background
- abduco and dvtm interpret it as green foreground
- JetBrains terminals interprets it as yellow background
- urxvt interprets it as yellow background
terminals that interpret curly as single underline:
- tmux [1]
- emacs ansi-term [2]
- emacs vterm
- GNU screen (also wrongly turns on italic mode)
- terminology (also wrongly turns on italic mode)
- Vim's :terminal

Our use of the terminfo database in /usr/share/terminfo/$TERM is both
1. a way for users to configure app behavior in their terminal (by
setting TERM, copying around and modifying terminfo files)
2. a way for terminal emulator developers to advertise support for
backwards-incompatible features that are not otherwise easily observable.
To 1: this is not ideal (it's very easy to break things). There's not many
things that realistically need configuration; let's use shell variables
instead.
To 2: in practice, feature-probing via terminfo is often wrong. There's not
many backwards-incompatible features that need this; for the ones that do
we can still use terminfo capabilities but query the terminal via XTGETTCAP
directly, skipping the file (which may not exist on the same system as
the terminal).
---
Get rid of terminfo. If anyone finds a $TERM where we need different behavior,
we can hardcode that into fish.
* Allow to override this with `fish_features=no-ignore-terminfo fish`
Not sure if we should document this, since it's supposed to be removed soon,
and if someone needs this (which we don't expect), we'd like to know.
* This is supported on a best-effort basis; it doesn't match the previous
behavior exactly. For simplicity of implementation, it will not change
the fact that we now:
* use parm_left_cursor (CSI Ps D) instead of cursor_left (CSI D) if
terminfo claims the former is supported
* no longer support eat_newline_glitch, which seems no longer present
on today's ConEmu and ConHost
* Tested as described in https://github.com/fish-shell/fish-shell/pull/11345#discussion_r2030121580
* add `man fish-terminal-compatibility` to state our assumptions.
This could help terminal emulator developers.
* assume `parm_up_cursor` is supported if the terminal supports XTGETTCAP
* Extract all control sequences to src/terminal_command.rs.
* Remove the "\x1b(B" prefix from EXIT_ATTRIBUTE_MODE. I doubt it's really
needed.
* assume it's generally okay to output 256 colors
Things have improved since commit 3669805627 (Improve compatibility with
0-16 color terminals., 2016-07-21).
Apparently almost every actively developed terminal supports it, including
Terminal.app and GNU screen.
* That is, we default `fish_term256` to true and keep it only as a way to
opt out of the the full 256 palette (e.g. switching to the 16-color
palette).
* `TERM=xterm-16color` has the same opt-out effect.
* `TERM` is generally ignored but add back basic compatiblity by turning
off color for "ansi-m", "linux-m" and "xterm-mono"; these are probably
not set accidentally.
* Since `TERM` is (mostly) ignored, we don't need the magic "xterm" in
tests. Unset it instead.
* Note that our pexpect tests used a dumb terminal because:
1. it makes fish do a full redraw of the commandline everytime, making it
easier to write assertions.
2. it disables all control sequences for colors, etc, which we usually
don't want to test explicitly.
I don't think TERM=dumb has any other use, so it would be better
to print escape sequences unconditionally, and strip them in
the test driver (leaving this for later, since it's a bit more involved).

This parser was pretty nice but it has some issues with the new syntax.
It's not really needed when most bindings use the new syntax.
Let's remove it altogether.
This except clause was too narrow, so it would fail here even on other
systems just because webbrowser.get() returned nothing usable
Now it will fail *later* with "could not locate runnable browser", but
at least it won't say anything about chromeos on non-chromeos systems.
Since the new expanded abbreviations in 3.6.0, abbr no longer accepts
new universal variables. That means this tab is now
non-functional (except that it could technically remove abbrs that
were set in universal variables).
Because making it work with the expanded abbreviations requires some
awkwardness like a dedicated conf.d snippet (or writing into
config.fish!), we simply remove it.
"socket.has_ipv6" is basically useless - it tells you python has
been *compiled* with ipv6 support.
Instead just try ipv6 and if that fails with EAFNOSUPPORT (checking
the actual errno), try v4.
Yes, I explicitly do not care to test this on python2.
Fixes#3857
This is a follow-up to #8811, which fixed fish_config on newer versions of
Sailfish OS.
Using the previous method to open the fish_config URL on Sailfish OS worked
only on 4.4 (and 4.3 IIRC), but not on older OS versions. Opening the URL
using xdg-open works well with new and old OS version, and has been tested on
- Sony Xperia 10 II running SFOS 4.4 aarch64
- Sony Xperia XA2 Ultra running SFOS 4.4 armv7hl
- Sony Xperia X running SFOS 4.1 armv7hl
- Jolla Phone running SFOS 3.4 armv7hl
Closes#8872
The `name` attribute I used in commit f725cd402d
is undocumented, and [someone discovered] that it does not exist for one
possible browser on MacOS. This should make the code work correctly even in that case.
This probably doesn't currently cause a problem, at least when
`isMacOS10_12_5_OrLater()` is true, because of the ordering of the if
statements in the `runThing` function.

If the theme says "brgreen", that's what we want the variable to say
after.
This used to translate it through our palette, so it ended up as
00ff00, which isn't the same.
This still keeps the idea that colors that aren't in the palette are
better, and it does it in a slightly roundabout way (translate color
string to rgb string, see if the rgb string is a key in that
translation dictionary), but it should work for now.
