This concerns running a key binding which invokes a command. If that
command modifies the tty, then fish will spot the modification later and
then react to it by redrawing the prompt. However tty modifications may
be benign or desirable; for example switching the cursor from a line to
a block. Fix this by re-fstating the tty after running external
commands.
Fixes#3481
Previously, `kill-whole-line` kills the line and its following
newline. This is insufficient when we are on the last line, because
it would not actually clear the line. The cursor would stay on the
line, which is not the correct behavior for bindings like `dd`.
Also, `cc` in vi-mode used `kill-whole-line`, which is not correct
because it should not remove any newlines. We have to introduce
another special input function (`kill-inner-line`) to fix this.
This teaches `--on-signal SIGINT` (and by extension `trap cmd SIGINT`)
to work properly in scripts, not just interactively. Note any such
function will suppress the default behavior of exiting. Do this for
SIGTERM as well.

../CHANGELOG.rst:123: WARNING: Bullet list ends without a blank line; unexpected unindent.
Pressing Ctrl-D while a command is running results in a null key code in
our input queue. That key code is bound to insert a space (without expanding
abbreviations). Make it only insert a space if the commandline is non-empty,
to accommodate this use case.
This probably affects other keys as well.
Closes#8871
c4fb857dac (in 3.4.1) introduced a regression where process_exit
events would only fire once the job itself is complete. Allow
process_exit events to fire before that. Fixes#8914.
We don't need to make the feature flag descriptions as terse as
possible, I believe some people were confused by what this all means,
so we can dedicate a few lines to explaining it again.

Prior to this change, if you tab-completed a token with a wildcard (glob), we
would invoke ordinary completions. Instead, expand the wildcard, replacing
the wildcard with the result of expansions. If the wildcard fails to expand,
flash the command line to signal an error and do not modify it.
Example:
> touch file(seq 4)
> echo file*<tab>
becomes:
> echo file1 file2 file3 file4
whereas before the tab would have just added a space.
Some things to note:
1. If the expansion would produce more than 256 items, we flash the command
line and do nothing, since it would make the commandline overfull.
2. The wildcard token can be brought back through Undo (ctrl-Z).
3. This only kicks in if the wildcard is in the "path component
containing the cursor." If the wildcard is in a previous component,
we continue using completions as normal.
Fixes#954.
When expanding command substitutions, we use a naïve way of detecting whether
the cmdsub has the optional leading dollar. We check if the last character was
a dollar, which breaks if it's an escaped dollar. We wrongly expand
\$(echo "") to the empty string. Fix this by checking if the dollar was escaped.
The parse_util_* functions have a bunch of output parameters. We should
return a parameter bag instead (I think I tried once and failed).
Given
set var a
echo "$var$(echo b)"
the double-quoted string is expanded right-to-left, so we construct an
intermediate "$varb". Since the variable "varb" is undefined, this wrongly
expands to the empty string (should be "ab"). Fix this by isolating the
expanded command substitution internally. We do the same when handling
unquoted command substitutions.
Fixes#8849
The tmp and prompt variables collide with variables used as arguments.
Just avoid them entirely, at the cost of making the internals of the
functions somewhat more complicated.
Closes#8836.
fish reads the tty modes at startup, and tries to restore them to the
original values on exit, to be polite. However this causes problems when
fish is run in a pipeline with another process which also messes with the
tty modes. Example:
fish -c 'echo foo' | vim -
Here vim's manipulation of the tty would race with fish, and often vim
would end up with broken modes.
Only restore the tty if we are interactive. Fixes#8705.
This is a big cleanup to how tty transfer works. Recall that when job
control is active, we transfer the tty to jobs via tcsetpgrp().
Previously, transferring was done "as needed" in continue_job. That is, if
we are running a job, and the job wants the terminal and does not have it,
we will transfer the tty at that point.
This got pretty weird when running mixed pipelines. For example:
cmd1 | func1 | cmd2
Here we would run `func1` before calling continue_job. Thus the tty
would be transferred by the nested function invocation, and also restored
by that invocation, potentially racing with tty manipulation from cmd1 or
cmd2.
In the new model, migrate the tty transfer responsibility outside of
continue_job. The caller of continue_job is then responsible for setting up
the tty. There's two places where this gets done:
1. In `exec_job`, where we run a job for the first time.
2. In `builtin_fg` where we continue a stopped job in the foreground.

Helm 3 provides an autogenerated completion since version 3.4.0.
The previous implementation is replaced by this because it was specific to the
now-deprecated helm 2.
The completions appear to be fully featured including descriptions and
completion for dynamic arguments such as namespaces and releases.
Their names are not perfect, so let's keep them as internal functions,
until we figure out how/if we want to expose this.
This reverts 0445126c2 (Undunder __fish_is_nth_token, 2021-06-29) (but I
did it without "git revert").
Closes#8008
If you have vim set up to recognize `.editorconfig` files, the 80-char limit
from ours causes vim to keep chopping lines. This makes it ignore that limit
when editing `CHANGELOG.rst`
Say the user has a multi-char binding (typically an escape sequence), and a
signal arrives partway through the binding. The signal has an event handler
which enques some readline event, for example, `repaint`. Prior to this
change, the readline event would cause the multi-char binding to fail. This
would cause bits of the escape sequence to be printed to the screen.
Fix this by noticing when a sequence was "interrupted" by a non-char event,
and then rotating a sequence of such interruptions to the front of the
queue.
Fixes#8628
Today, a command like "var=val status " has custom completions
because we skip over the var=val variable override when detecting
the command token.
However if the custom completions read the commandline state (via
"commandline -opc") they do see they variable override, which breaks
them, most likely. Try "a=b git ".
For completions of wrapped commands, we already set a transient
commandline. Do the same for commands with leading variable overrides;
then git completions for "a=b git " will think the commandline is
"git ".
I used the command from #8092 to list issues/PRs with missing changelog
entries, and went through most of them and added them to the changelog
(or the "ignore" list).
This commit message lists the processed issues in a consistent format,
and lists the action/reason. For each issue/PR there are twolines:
- Issue/PR number + subject
- (I used bare issue numbers to avoid cross-referencing on github).
- verdict
- "added new entry" means that we add a changelog line
- "added to existing entry" means that we added the issue link to an existing
changelog line. Usually we don't add multiple issue links, but sometimes
there are multiple interesting issues.
- if the verdict ends with ", ignoring", we added it to the "ignore" list in
the changelog.
The issues are grouped by verdict, with the interesting/leftover ones
on top.
The "gh" script is already a quantum leap but we should still find
better ways to share the burden of writing the changelog.
I noticed that there are many minor updates that can probably be
ignored. Filtering them out doesn't take much time but it adds up,
especially if it's a single person doing it.
Here's the adapted script I used:
for issue in (gh issue list --state closed --milestone "fish 3.4.0" -L 500 | sort -n | cut -f 1)
egrep --quiet '\W'$issue CHANGELOG.rst; or echo https://github.com/fish-shell/fish-shell/issues/$issue
end
for pr in (gh pr list --state all --search "milestone:\"fish 3.4.0\"" -L 500 | sort -n | cut -f 1)
egrep --quiet '\W'$pr CHANGELOG.rst; or echo https://github.com/fish-shell/fish-shell/pull/$pr
end

Closes#8485
A completion entry like «complete -a '\\~'» results in completions
that insert \~ into the command line. However we usually want to
insert ~, but there is no way to do that.
There are a couple of longstanding issues about completion escaping
[1]. Until we fix those in a general way, fix the common case by
never escaping tildes when applying custom completions to the command
line. This is a hack but will probably work out fine because we don't
expect literal tildes in arguments.
The tilde is included in completions for cdh, or
__fish_complete_suffix, which simply forwards results from "complete
-C". Revert a workaround to cdh that expanded ~, because we can now
render that without escaping.
Closes#4570, #8441

Currently,
set -q --unpath PATH
simply ignores the "--unpath" bit (and same for "--path").
This changes it, so just like exportedness you can check pathness.
On a commandline like "ls arg" (cursor at end) we do not expand
abbrevations on enter. OTOH, on "ls " we do expand. This can be
frustrating because it means that the two obvious ways to suppress
abbrevation expansion (C-Space or post-expansion C-Z) cannot be used to
suppress expansion of a command without arguments. (One workaround is
"ls #".)
Only expand-on-execute if the cursor is at the command name (no space
in between).
This is a strict improvement for realistic scenarios, because if there
is a space, the user has already expressed the intent to not expand
the abbreviation. (I hope no one is using recursive abbreviations.)
Closes#8423
- More Notable

This program uses the Cobra framework for argument parsing and completion generation.
Just source the completions supplied by upstream.
This works around "go install" not being able to install completions files (only binaries).
Similar to `test`, `_` is so likely to at least slow down if not
break all things catastrophically that it ought not be allowed as a
function name. Fixes#8342
Mac OS 10.9 does not have the fstatat function which fish started
calling in commit 71a0d839a7. Let's end support for 10.9, which was
released in 2013.
The less -F / --quit-if-one-screen option is buggy before v530. To work
around this, pass --no-init less versions older than 530.
The --no-init option was previously passed; it was removed in d15a51897d
for mouse support. Unfortunately it looks like we can't have mouse
support and --quit-if-one-screen on macOS shipped less (version 487).
It's worth fixing this because otherwise history and help is just not
printed on stock macOS.
Relevant is https://unix.stackexchange.com/questions/107315/less-quit-if-one-screen-without-no-initFixes#8157.
Now that we removed EROTTEN which had the same error code as EPERM,
we can give a less confusing error in case a user has not allowed
their terminal access to a directory.
See #8264
When cd is passed a broken symlink, this changes the error message from
"no such directory" to "broken symbolic link". This scenario probably
won't happen very often since completion won't suggest broken symlinks
but it can't hurt to give a good error.
Fish used to do this until 7ac5932. This logic used to be in
path_get_cdpath, however, that is only used for highlighting, so we
don't need error messages there. Changing cd is enough.
Reword from "rotten" to "broken" since that's what file(1) uses.
Clean-up leftovers from old "rotten" code (nomen est omen).

This disables job control inside command substitutions. Prior to this
change, a cmdsub might get its own process group. This caused it to fail
to cancel loops properly. For example:
while true ; echo (sleep 5) ; end
could not be control-C cancelled, because the signal would go to sleep,
and so the loop would continue on. The simplest way to fix this is to
match other shells and not use job control in cmdsubs.
Related is #1362
This is opt-in through a new feature flag "ampersand-nobg-in-token".
When this flag and "qmark-noglob" are enabled, this command no longer
needs quoting:
curl https://example.com/thing?foo=bar&duran=duran
Compared to the previous approach e1570a4 ("Let '&' only separate as
the first char of a word"), this has some advantages:
1. "&&" and "&>" are no longer affected. They are still special, even
if used between tokens without spaces, like "echo bar&>foo".
Maybe this is not really *better*, but it avoids risking to annoy
users by breaking the old variant.
2. "&" is still special if at the end of a token, like in "sleep 1&".
Word movement is not affected by the semantics change, so Alt-F and
friends still stop at every "&".
When the user presses control-C, fish marks a cancellation signal which
prevents fish script from running, allowing it to properly unwind.
Prior to this commit, the signal was cleared in the reader. However this
missed the case where a binding would set $fish_bind_mode which would
trigger event handlers: the event handlers would be skipped because of
the cancellation flag was still set. This is similar to #6937.
Let's clear the flag earlier, as soon as we it's set, in inputter_t.
Fixes#8125.
This introduces two functions to
- toggle a process prefix, used for adding "sudo"
- add a job suffix, used for adding "&| less"
Not sure if they are very useful; we'll see.
Closes#7905

Now that `$last_pid` is never fish's pid, we no longer need to force
jobs to run in their own pgroup. Restore the job control behavior to
what it was prior, so that signals may be delivered properly in
non-interactive mode.
This reverts commit 3255999794
Prior to this change, a function with an on-job-exit event handler must be
added with the pgid of the job. But sometimes the pgid of the job is fish
itself (if job control is disabled) and the previous commit made last_pid
an actual pid from the job, instead of its pgroup.
Switch on-job-exit to accept any pid from the job (except fish itself).
This allows it to be used directly with $last_pid, except that it now
works if job control is off. This is implemented by "resolving" the pid to
the internal job id at the point the event handler is added.
Also switch to passing the last pid of the job, rather than its pgroup.
This aligns better with $last_pid.
When a job is placed in the background, fish will set the `$last_pid`
variable. Prior to this change, `$last_pid` was set to the process group
leader of the job. However this caussed problems when the job ran in
fish's process group, because then fish itself would be the process group
leader and commands like `wait` would not work.
Switch `$last_pid` to be the actual last pid of the pipeline. This brings
it in line with the `$!` variable from zsh and bash.
This is technically a breaking change, but it is unlikely to cause
problems, because `$last_pid` was already rather broken.
Fixes#5036Fixes#5832Fixes#7721
It is possible to run a function when a process exits via `function
--on-process-exit`, or when a job exits via `function --on-job-exits`.
Internally these were distinguished by the pid in the event: if it was
positive, then it was a process exit. If negative, it represents a pgid
and is a job exit. If zero, it fires for both jobs and processes, which is
pretty weird.
Switch to tracking these explicitly. Separate out the --on-process-exit
and --on-job-exit event types into separate types. Stop negating pgids as
well.
This switches builtin_wait from waiting on jobs in the active job list, to
waiting on the wait handles. The wait handles may be either derived from
the job list itself, or from saved wait handles from jobs that exited in
the background.
Fixes#7210
Prior to this fix, an escaped character like \x41 (hex for ascii A)
was interpreted the same was as A, so that $\x41 would be the same
as $A. Fix this by inserting an INTERNAL_SEPARATOR before these escapes,
so that we no longer treat it as part of the variable name.
This also affects brackets; don't treat echo $foo\1331\135 the same as
echo $foo[1].
Fixes#7969
In many cases we currently discard escaped newlines, since they
are often unnecessary (when used around &|;). Escaped newlines
are useful for structuring argument lists. Allow them for variable
assignments since they are similar.
Closes#7955
This refactors the behavior of string match with capture groups to
correctly handle multiple arguments. Now the variable capture applies to
the first match, as documented. Fixes#7938.
string match is documented as setting an unset variable if a capture group
is unmatched in an otherwise matched regex, and if the `--all` flag is not
provided. However prior to this fix, it instead set a variable containing
the empty string as a single value. Correct the implementation to match
the documentation.
Note that if the `--all` flag is provided we continue to set empty
strings, which is documented.
This correctly sets $status when a builtin succeeds but its output fails;
for example if the output is redirected to a file and that write fails.
Fixes#7857
When building the document with Sphinx, the following warning is displayed, so add end-string.
"../CHANGELOG.rst:29: WARNING: Inline literal start-string without end-string."
This fixes the following problem: if a command is entered while the
previous command is still executing, fish will see it all at once and
execute it before syntax highlighting as a chance to start. So the
command will appear wrong on the terminal. Fix this by detecting this
case and performing a fast no-io highlight.
An example of how to reproduce this:
run `sleep 3` and then type `echo foo` while the sleep is still running.
This cleans up some exit code processing. Previously a failed exec
would produce exit code 125 unconditionally, while a failed posix_spawn
would produce exit code 1 (!).
With this change, fish reports exit code 126 for not-executable, and 127
for file-not-found. This matches bash.
When regenerating documentation with Sphinx, there's a warning issued about CHANGELOG.rst:
```
../CHANGELOG.rst:33: WARNING: Document or section may not begin with a transition.
```
This is almost identical to the fix in commit 84a89f5195.
Consider
$ complete -c foo -a 'aab aaB' -f
$ foo A<TAB>
since 28d67c8 we would insert the common prefix AND show the pager.
Due to case-insensitive comparison, "b/B" was considered to be part
of the prefix. Since the prefix is added to each pager item [1]
we get wrong results. Fix this by removing the insensitive comparison
between completions - I don't think it was of much use anyway.
Commandline tokens are still matched case-insensitively, this is
just about completions.
Test this by running interactive fish inside tmux (pexpect's terminal
emulation not have enough capabilities). Also add tests for recent
interactive regressions #7526 and #7738.
Closes#3978
[1]: b38a23a would solve this differently by giving every pager item
its own prefix, but was reverted since it needs more fixes.
* Rewrite the real file if history file is a symlink
When the history file is a symbolic link, `fish` used to overwrite
the link with a real file whenever it saved history. This makes
it follow the symlink and overwrite the real file instead.
The same issue was fixed for the `fish_variables` file in 622f2868e
from https://github.com/fish-shell/fish-shell/pull/7728.
This makes `fish_history` behave in the same way. The implementation
is nearly identical.
Since the tests for the two issues are so similar, I combined them
together and slightly expanded the older test.
This also addresses https://github.com/fish-shell/fish-shell/issues/7553.
* Add user-facing error when history renaming fails
Currently, when history file renaming fails, no message is shown to the
user. This happens, for instance, if the history file is a symlink
pointing to another filesystem.
This copies code (with a bit of variation, after reviewer comments) from
589eb34571/src/env_universal_common.cpp (L486-L491)
into `history.cpp`, so that a message is shown to the user.
* fixup! Rewrite the real file if history file is a symlink
When `fish` is running in the Chrome OS Linux VM (Crostini),
both `help` and `fish_config` opened a "file not found"
page. That is because on Crostini, `BROWSER` is usually set to
`garcon-url-handler`, which opens URLs in the host OS Chrome
browser. That browser lacks access to the Linux file system.
This commit fixes these commands. `help` now opens the URL on
www.fishshell.com. `fish_config` now opens the URL for the
server it starts. Previously, it opened a local file that
redirects to the same URL.
In the case of `help`, the situation could be improved further
by starting a web server to serve help. I don't know of another
way to access `/share/fish` from outside the VM without user
intervention, and I think that might be a part of the security
model for the Crostini VM.
It's hard to write a test for this. I checked that `help math`,
`python2 webconfig.py`, and `python3 webconfig.py` work on my
machine running in Crostini.
In this context, as it stands, $last_pid will give fish's pid (because
of pgroup shenanigans).
Since that doesn't really work, just `disown` without and let fish
figure out what the last process was.
Theoretically this has an issue if someone started a background
process *before* the python script *and* that exits before we run
disown.
That's a vanishingly small window and this is only run on first start,
so it seems acceptable.
Fixes#7739.
Apparently the fix for #6269 doesn't work until we set job-control to
full, which we won't do for this release.
So just drop it from the CHANGELOG.
See #7739.
The user may write for example:
echo foo >&5
and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.
Note that the reverse is "allowed" but ignored:
echo foo 5>&1
this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.
Similar to what fish_indent does. After typing "echo \" and hitting return,
the cursor will be indented.
A possible annoyance is that when you have multiple indented lines
echo 1 \
2 \
3 \
4 \
If you remove lines in the middle with Control-k, the lines below
the deleted one will start jumping around, as they are disconnected
from and reconnected to "echo".
If a variable is undefined, but it looks like it will be defined by the
current command line, assume the user knows what they are doing.
This should cover most real-world occurrences.
Closes#6654
When pasting a multiline command with indented blocks, extra indentation
from spaces, or tabs, is generally undesirable, because fish already indents
pipes and blocks. Discard the indentation unless the cursor or the pasted
part is inside quotes.
Users who copied fish_clipboard_paste need to update it because
__fish_commandline_is_singlequoted had an API change and was renamed.
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.
This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.
Prior to this fix, if stdin were explicitly closed, then builtins would
silently fail. For example:
count <&-
would just fail with status 1. Remove this limitation and allow each
builtin to handle a closed stdin how it sees fit.
builtin_set_query returns the number of missing variables. Because the
return value passed to the shell is an 8-bit unsigned integer, if the
number of missing variables is a multiple of 256, it would overflow to 0.
This commit saturates the return value at 255 if there are more than 255
missing variables.

Some third party Git tools provide a man page, which we can at least use
for completing options.
The old logic excluded all generated completions for Git subcommands.
Instead, try to load completions for all available external subcommands.
We can use $PATH/git-* because /bin/git-add and friends were removed in Git
1.6.0 in 2008.
Closes#4358 (the "git-foo" wrapping was added in #7652)
Since #7075, git-foo.fish files are sourced when Git completions are loaded.
However, at least Cobra (CLI framework for Go) provides completions like
complete git-foo ...
This means that completions are only offered when typing "git-foo <TAB>"
and not on "git foo <TAB>". Fix this by forwarding the completion requests.
Take care to only forward if there are actually completions for "git-foo",
to avoid adding filename completions.
It also reflows.
We might want to think about doing something more extensible here, as
konsole is also about to add reflow, but for now the main problem
children here are VTE and alacritty.
Extends #7491.
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
Prior to this change, if fish were launched connected to a tty but not as
pgroup leader, it would attempt to become pgroup leader only if
--interactive is explicitly passed. But bash will unconditionally attempt
to become pgroup leader if launched interactively. This can result in
scenarios where fish is running interactively but in another pgroup. The
most obvious impact is that control-C will result in the pgroup leader
(not fish) exiting and make fish orphaned.
Switch to matching the bash behavior here - we will always try to become
pgroup leader if interactive.
Fixes#7060.
"smartcase" performs case-insensitive matching if the input string is all
lowercase, and case-sensitive matching otherwise. When completing e.g.
files, we will now show both case sensitive and insensitive completions if
the input string does not contain uppercase characters.
This is a delicate fix in an interactive component with low test coverage.
It's likely something will regress here.
Fixes#3978
When fish presents an autosuggestion, there is some logic around whether
to retain it or discard it as the user types "into" it. Prior to this
change, we would retain the autosuggestion if the user's input text is a
case-insensitive prefix of the autosuggestion. This is reasonable for
certain case-insensitive autosuggestions like files, but it is confusing
especially for history items, e.g. `git branch -d ...` and `git branch -D
...` should not be considered a match.
With this change, when we compute the autosuggestion we record whether it
is "icase", and that controls whether the autosuggestion permits a
case-insensitive extension.
This addresses part of #3978.
The builtin-buffering thing is huge and should be early in the big
ticket items, the performance improvement to completion of commands is
cool but not all that important.
[ci skip]
jobs -p %1 prints all processes in the first job.
fg is special because it only takes one argument. Using the last process
in the pipeline works for the cases I can think of.
Fixes#7406
These aliases seem to be common, see #7389 and others. This prevents
recursion on that example, so `alias ssh "env TERM=screen ssh"` will just
have the same completions as ssh.
Checking the last token is a heuristic which hopefully works for most
cases. Users are encouraged to use functions instead of aliases.
