c0bcd817ba removed some key bindings, including the bindings of
ESC ESC [ C for Alt-Right. the commit claimed that
"Sequences like \e\eOC are Escape followed by an SS3 arrow key which we
can already decode separately." but for whatever reason this doesn't work:
Alt-Right is broken in iTerm2 by default.
Restore the default ESC ESC [ X bindings for iTerm2 compatibility.
Don't unconditionally execute the plumbing to get `rustc -C` completions (use it
only when trying to complete `rustc -C`), filter out deprecated options, and use
fewer calls to the `string` builtin to optimize further.
Need to do the same thing for the `-Z` completions next, those hang the shell
for a good 1.5+ seconds.
I've been needing this for some time to generate completions for functions that
we can dynamically generate completions for that take one or more
comma-separated values in any order.
Try not to let `cargo asm` build a large project and hang the terminal (and make
the fans go crazy) if we try to generate a list of functions/paths and the
project is in a dirty state. Also support dynamic completion of --target.
If rustup is installed, use the existing `__rustup_installed_targets` to get a
list of installed targets to compile for. If it's not, print a list of all
targets known to rustc.
It sucks that the completions file is currently architected in a way where we
have to manually specify the arguments for each subcommand. 🤷
- Remove duplicated options - we had `-type` 9 times!
- Remove deprecated options and synonyms
- Make descriptions shorter, even removing some - when they're inscrutable they might as well not be there.
Really, 99.8% of these options are of interest to nobody except possibly (a subset of) gcc developers, so it pays to have *less* on your screen that you don't use anyway.
We ignore typed control characters 33a7172ee (Revert to not inserting control
characters from keyboard input, 2024-03-02).
We used to do the same for bracketed paste but that changed in 8bf8b10f6
(Extended & human-friendly keys, 2024-03-30) which made bracketed paste
behave like fish_clipboard_paste; it inserts the exact input (minus leading
whitespace etc). At that time it wasn't clear to me which behavior was the
right one (because of the inconsistency between terminal and bracketed paste).
As reported in
https://matrix.to/#/!YLTeaulxSDauOOxBoR:matrix.org/$PEEOAoyJY-644amIio0CWmq1TkpEDdSy2QnfJdK-dco
trailing tabs in pasted text can be confusing.
There seems to be not real need to insert raw control characters into the
command line, so let's strip them when pasting.
Now the only way to insert a raw control character into the command line is
to recall it from command history. Not sure what the behavior should be for
that case, we can revisit that later. If we get rid of raw control characters
entirely, then we can also delete the new "control pictures" rendering :)
Given "abbr foo something", the input sequence
foo<space><ctrl-z><space>
would re-expand the abbreviation on the second space which is surprising
because the cursor is not at or inside the command token. This looks to be
a regression from 00432df42 (Trigger abbreviations after inserting process
separators, 2024-04-13)
Happily, 69583f303 (Allow restricting abbreviations to specific commands
(#10452), 2024-04-24) made some changes that mean the bad commit seems no
longer necessary. Not sure why it works but I'll take it.
In addition to the native Emacs undo binding, we also support ctrl-z.
On Linux, ctrl-shift-z alias ctrl-Z is the redo binding according to
https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts Let's bind allow
that.
Unfortunately ctrl-shift and ctrl-alt modified shortcuts on Linux may be
intercepted by the windowing system or the terminal. Only alt-shift seems to be
available reliably (but the shift bit should mean "extend selection" in Emacs).
iTerm2 supports CSI u so the custom bindings are no longer needed. Sequences
like \e\eOC are Escape followed by an SS3 arrow key which we can already
decode separately.
In ImageMagick 7 or later, legacy commands have been replaced with
magick. Here a new functions, defines these completions and it is
called for `magick` and `magick convert`.
fixes#7172. Closes#10307.

We were inconsistent about this for no apparent reason.
Also cleaning up in ~/.config/fish/completions is
irrelevant by now since we moved to ~/.local/share/fish 8 years ago.
Now that the parent commit moved it again, cleaning up that one seems
reasonable.
wl-copy is a daemon process that serves its stdin to any wl-paste processes.
On Wayland, we launch it from fish_clipboard_copy. It then lives in the
same process group as fish (see `ps -o pid,pgid,comm`).
For some reason pressing ctrl-c inside the VSCode integrated terminal with
fish as the default shell kills the wl-copy process, thus clearing the
clipboard. On other terminals it works fine.
This is also reproducible by running "echo foo | wl-copy" ctrl-v ctrl-c ctrl-v
(the second ctrl-v does not paste because wl-copy was killed).
Work around this for now by running wl-copy asynchronously, and disowning it.
This seems to fix it though I really don't know why. Alternatively we could
"setsid" but that's technically not available on BSD.
For some reason this works in Bash. We should strace it to figure out why.
alt-d used to do that until evil merge[*] 213e90704 (Merge remote-tracking branch
'upstream/master' into bind_mode, 2014-01-15) which changed the order of
the \ed bindings such that the smart dirh version would be shadowed by the
simpler ones.
[*] git blame alone failed to find it because it skips merge commits.
There seem to be versions of ssh (possibly not from OpenSSH) that don't
print the version number in -V, so make sure not to pass an empty string as
numeric arg to test.
Fixes#10445
This is another problem that has been bothering me for years: as mentioned
in 1dd901e52 (Maintain cursor in history prefix search, 2024-04-12), up-arrow
search highlights search matches but the contrast is really bad, especially in
command position, because the search matches --background=brblack is combined
with whatever foreground syntax highlighting the command has. The history
pager had a similar problem (for the selected history item) but circumented
it by disabling syntax highlighting altogether for the selected item.
fish_color_search_match's foreground component is ignored.
Let's use it instead of syntax highlighting.
This fixes the contrast on some default colorschemes but the bryellow
foreground looks weirdly like an error/warning on some terminals. Change it
to white. This needs a hack because we don't have a canonical way to tell
if a uvar has been set by the user. Fortunately the foreground component
hasn't been used at all so far, so we're not so much changing it as much as
initializing it.
Indented multiline commandlines look ugly in an external editor. Also,
fish doesn't properly handle the case when the editor runs fish_indent.
Fix is by indenting when exporting the commandline and un-indenting when
importing the commandline again.
Unindent only if the file is properly indented (meaning at least by the
amount fish would use). Another complication is that we need to offset
cursor positions by the indentation.
This approach exposes "fish_indent --only-indent" and "--only-unindent"
though I don't imagine they are useful for others so I'm not sure if this
is the right place and whether we should even document it.
One alternative is to add "commandline --indented" to handle indentation
transparently.
So "commandline --indented" would print a indented lines,
and "commandline --indented 'if true' ' echo'" would remove the unecessary
indentation before replacing the commandline.
That would probably simplify the logic for the cursor position offset.
On
a;
we don't expand the abbreviation because the cursor is right of semicolon,
not on the command token. Fix this by making sure that we call expand-abbr
with the cursor on the semicolon which is the end of the command token.
(Now that our bind command execution order is less surprising, this is doable.)
This means that we need to fix the cursor after successfully expanding
an abbreviation. Do this by setting the position explicitly even when no
--set-position is in effect.
An earlier version of this patch used
bind space self-insert backward-char expand-abbr or forward-char
The problem with that (as a failing test shows) was that given "abbr m
myabbr", after typing "m space ctrl-z", the cursor would be after the "m",
not after the space. The second space removes the space, not changing the
cursor position, which is weird. I initially tried to fix this by adding
a hack to the undo group logic, to always restore the cursor position from
when begin-undo-group was used.
bind space self-insert begin-undo-group backward-char expand-abbr end-undo-group or forward-char
However this made test_torn_escapes.py fail for mysterious reasons.
I believe this is because that test registers and triggers a SIGUSR1 handler;
since the signal handler will rearrange char events, that probably messes
with the undo group guards.
I resorted to adding a tailor-made readline cmd. We could probably remove
it and give the new behavior to expand-abbr, not sure.
Fixes#9730
Some of these handled multiline prompts but not multiline command lines. We
first need to move the cursor to the end of the commandline, then we can
print a message. Finally, we need to move the cursor back to where it was.
This allows terminals like foot and kitty to
* scroll to the previous/next prompt with ctrl-shift-{z,x}
* pipe the last command's output to a pager with ctrl-shift-g
Kitty has existing fish shell integration
shell-integration/fish/vendor_conf.d/kitty-shell-integration.fish which we
can simplify now. They keep a state variable to decide which of prompt start,
command start or command end to output. I think with our implementation
this is no longer necessary, at least I couldn't reproduce any difference.
We also don't need to hook into fish_cancel or fish_posterror like they do;
only in the one place where we actually draw the prompt.
As mentioned in the above shell integration script, kitty disables reflow
when it sees an OSC 133 marker, so we need to do it ourselves,
otherwise the prompt will go blank after a terminal resize.
Closes#10352
If I type
$ echo $SOME_VARIABLE_WIHT_A_TYPO
$ set -S SOME_VARIABLE_WIHT
and press tab, I'm always extremely surprised that this completes to
$ set -S fish_history
which is because $history[1] contains the typo'd variable name. I don't
think anyone intends to filter by that last 3-4 history items, so let's
remove this pitfall.
Note that I usually hit this scenario with undefined variables, not necessarily
typos.. "set -S" is usually redundant but it's still quite nice in this case,
to rule out any weird empty strings/empty lists.
Similar to 20bbdb68f (Set terminal title unconditionally, 2024-03-30).
While at it, get rid of a few unnecessary guards (we are never called from
a command substitution, so the check only adds confusion).
I'm not sure if it's worth supporting a terminal that mishandles unknown OSC
and CSI sequences. Better to fix the terminal. Note that there are Emacs
terminals available that don't have this problems; for example "vterm".
See the changelog additions for user-visible changes.
Since we enable/disable terminal protocols whenever we pass terminal ownership,
tests can no longer run in parallel on the same terminal.
For the same reason, readline shortcuts in the gdb REPL will not work anymore.
As a remedy, use gdbserver, or lobby for CSI u support in libreadline.
Add sleep to some tests, otherwise they fall (both in CI and locally).
There are two weird failures on FreeBSD remaining, disable them for now
https://github.com/fish-shell/fish-shell/pull/10359/checks?check_run_id=23330096362
Design and implementation borrows heavily from Kakoune.
In future, we should try to implement more of the kitty progressive
enhancements.
Closes#10359
To do so add an ad-hoc "commandline --search-field" to operate on pager
search field.
This is primarily motivated because a following commit reuses the
fish_clipboard_paste logic for bracketed paste. This avoids a regression.
Unfortunately on Debian "open" is a symlink to "openvt", and there's
no way from outside to tell.
This prevents fish from failing because no browser could be found.
Today fish_cursor_selection_mode controls whether selection mode includes
the cursor. Since it's by default only used for Vi mode, perhaps use it to
also decide whether it should be allowed to select one-past the last character.
Not allowing to select to select one-past the last character is much nicer
in Vi mode. Unfortunately Vi mode sometimes needs to temporarily select
past end (using forward-single-char and such), so reset fish_cursor_selection_mode
for the duration of the binding.
Also fix other things like cursor placement after yank/yank-pop.
Closes#10286Closes#3299
We have
bind --preset -M $mode --sets-mode paste \e\[200~ __fish_start_bracketed_paste
Commit c3cd68dda (Process shell commands from bindings like regular char
events, 2024-03-02) made it so __fish_start_bracketed_paste is no longer
executed before the bind mode is updated.
This is a long-awaited fix but it broke __fish_start_bracketed_paste's
assumption that $fish_bind_mode is the mode before we entered paste mode.
This means we never exit paste mode.
Work around that. I forgot about this issue because I already replaced our
bracketed paste handling on my fork.
