When the user clicks somewhere in the prompt, kitty asks the shell
to move the cursor there (since there is not much else to do).
This is currently implemented by sending an array of
forward-char-passive commands. This has problems, for example it
is really slow on large command lines (probably because we repaint
everytime).
Implement kitty's `click_events=1` flag to set the
position directly. To convert from terminal-coordinates
to fish-coordinates, query [CSI 6 n Report Cursor
Position](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html)
and use it to compute the left prompt's terminal-coordinates (which
are (0, 0) in fish-coordinates).
Unfortunately this doesn't work correctly while the terminal is
scrolled. This is probably because the cursor position is wrong
if off-screen. To fix that we could probably record the cursor
position while not scrolled, but it doesn't seem terribly important
(the existing implementation also doesn't get it right).
Also add parsing for some unused mouse events; I'll probably remove
them again unless we can use them now.
Future work:
1. Knowledge of the position of the prompt will
also enable us to make [ctrl-l scroll instead of erasing]
(https://codeberg.org/dnkl/foot/wiki#how-do-i-make-ctrl-l-scroll-the-content-instead-of-erasing-it)
(as of wiki commit b57489e298f95d037fdf34da00ea60a5e8eafd6d) which
might be a better default.
2. We still turn off mouse reporting. If we turned it on, it
would be harder to select text in the terminal itself (not fish).
This would typically mean that mouse-drag will alter fish's
selection and shift+mouse-drag or alt+mouse-drag can be used.
To improve this, we could try to synchronize the selection:
if parts of the fish commandline are selected in the terminal's
selection, copy that to fish's selection and vice versa.
Or maybe there is an intuitive criteria, like: whenever we receive
a mouse event outside fish, turn off mouse reporting, and turn
it back on whenver we receive new keyboard input. One problem
is that we lose one event (though we could send it back to the
terminal). Another problem is we would turn it back on too late
in some scenarios.
* Pass path to install()
It was dirty that it would re-get $HOME there anyway.
* Import wcs2osstring
* Allow installable builds to use a relocatable tree
If you give a path to `--install`, it will install fish into a
relocatable tree there, so
PATH/share/fish contains the datafiles
PATH/bin/fish contains the fish executable
PATH/etc/fish is sysconf
I am absolutely not sold on that last one - the way I always used
sysconfdir is that it is always /etc. This would be easy to fix but
should probably also be fixed for "regular" relocatable builds (no
idea who uses them).
An attempt at #10916
* Move install path into "install/" subdir
* Disable --install harder if not installable
I forgot that 610338cc70 (On undo after execute, restore the cursor
position, 2024-12-21) would cause a fallout to tests:
It makes us reuse in another place our usual cursor-movement sequences.
This causes failures like this (linebreaks added for readability):
Testing file pexpects/bind.py:Failed to match pattern: (?:\r\n|\x1b\[2 q)[^\n]*def abc\r\n
bind.py:45: timeout from expect_prompt(TO_END + "def abc\r\n") # emacs transpose words, default timeout: no delay
Escaped buffer:
\x1b[?2004h\x1b[>4;1m\x1b[=5u\x1b=\rprompt 2>echo \rprompt 2>echo abc \rprompt 2>echo def abc\r
prompt 2>echo def abc\x1b[?2004l\x1b[>4;0m\x1b[=0u\x1b>\x1b]133;C\x07def abc\r\n\x1b]133;D;0\x07\x1b[?25h⏎
\r⏎ \r\rprompt 3>\x1b[?2004h\x1b[>4;1m\x1b[=5u\x1b=
It seems that we don't print anything where we should print something
like "\r\n" or "\e[2 q" to move the cursor below the command line.
I haven't gotten to the bottom of this but it might be related to
terminfo. Once we get rid of that, we can unconditionally print
our canonical movement sequences.
This issue seems to only affect tests, since fish operates fine in
a sourcehut CI system. Let's ignore it for now.
Ever since 149594f974 (Initial revision, 2005-09-20), we move the
cursor to the end of the commandline just before executing it.
This is so we can move the cursor to the line below the command line,
so moving the cursor is relevant if one presses enter on say, the
first line of a multi-line commandline.
As mentioned in #10838 and others, it can be useful to restore the
cursor position when recalling commandline from history. Make undo
restore the position where enter was pressed, instead of implicitly
moving the cursor to the end. This allows to quickly correct small
mistakes in large commandlines that failed recently.
This requires a new way of moving the cursor below the command line.
Test changes include unrelated cleanup of history.py.
Commit 8bf8b10f68 (Extended & human-friendly keys, 2024-03-30) stopped
ctrl-c from exiting without a motivation. Unfortunately this was
only noticeable on terminals that speak the kitty keyboard protocol,
which is probably no one had noticed so far.
Closes#10928
This reverts commit 27c7578760.
dust generates its own completions (which are shipped in the wrong spot
in the Debian packages, but which are also more up-to-date).
Closes#10922.
The apple-codesign crate has a fairly aggressive MSRV policy, and the
compiler itself still targets 10.12 which is well below the minimum
version of macOS for aarch64. Just use stable.
The version of rclone is set during compilation and could be any crazy string depending on the packager, whether it's a dev build, etc. If it cannot be parsed, let's assume a recent version.
Follows up on cc8fa0f7
This is allowed
time a=b echo 123
but -- due to an oversight in 3de95038b0 (Make "time" a job prefix,
2019-12-21) -- this is not allowed:
not time a=b echo 123
Instead, this one one works:
not a=b time echo 123
which is weird because without the "not" this would run "/bin/time".
It seems wrong that "not" is not like the others. Swap the order
for consistency.
Note that unlike "not", "time" currently needs to come before variable
assignments, so "a=b time true" is disallowed. This matches zsh. POSIX
shells call "/bin/time" here. Since it's ambiguous, erroring out seems
fine. It's weird that we're inconsistent with not here but I guess
"command not" is not expected to have subtly different behavior.
Closes#10890
This was added accidentally in 971d257e67 (Port AST to Rust,
2023-04-02). It does not seem to be causing an observable effect
(although I didn't try hard).
It's pretty annoying that this panics without sphinx, because the
install itself would be *working*.
So instead we tell the user that they need to clean or set
$FISH_BUILD_DOCS if they want to try again.
We get "undefined reference to `__memmove_chk'" when compiling
pcre2 (via pcre2-sys) on newer Ubuntu.
That one is used with higher fortify_source levels, and Ubuntu 24.04
defaults to 3, while my arch system (where I cannot reproduce)
defaults to 2.
The values we would try are:
xterm-256color, xterm, ansi, dumb
This is a pretty useless list, because systems without
"xterm-256color" but with "ansi" basically don't exist,
and it is very likely that the actual terminal is more
xterm-compatible than it is ansi.
So instead we just use our xterm-256color definition, which has a high
likelihood of being basically correct.
This is fairly subtle.
When installable, and we either can't find the version file or it is
outdated, we ask the user to confirm installation (just like `--install`).
We do that only if we are really truly interactive (with a tty!) to
avoid `fish -c` running into problems.
This check could be tightened even more, because currently:
```fish
fish -ic 'echo foo'
```
asks, while
```fish
fish -ic 'echo foo' < /dev/null
```
does not.
`fish -c` will still error out if it can't find the config, but it
will just run if it is out of date.
