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.

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.
If the padding is not divisible by the char's width without remainder,
we pad the remainder with spaces, so the total width of the output is correct.
Also add completions, changelog entry, adjust documentation, add examples
with emoji and some tests. Apply some minor style nitpicks and avoid extra
allocations of the input strings.

This makes history searches case-insensitive, unless the search string
contains an uppercase character.
This is what vim calls "smartcase".
Fixes#7273.
Now command, jobs, type, abbr, builtin, functions and set take `-q` to
query for existence, but the long option is inconsistent.
The first three use `--quiet`, the latter use `--query`. Add `--query`
to the first three, but keep `--quiet` around.
Fixes#7276.
The line offset of a trailing newline on the commandline was computed incorrectly.
As a result, up-arrow did not work for a commandline like the one inserted by:
commandline -i echo '' ''
Note this and the previous commit in the changelog.
This can be used to determine whether the previous command produced a real status, or just carried over the status from the command before it. Backgrounded commands and variable assignments will not increment status_generation, all other commands will.
This pulls in widechar_width.h from commit 7e9dfdaf05059b3f. The big change
here is that some characters which were previously marked as widened in 9
are now marked as unconditionally narrow; this includes some randoms like
hot pepper (U+1F336) but more importantly all of the regional indicators,
which affects how flags are rendered.
If you put two regional indicators together, you get a flag emoji. It's
unclear what the width of this flag emoji should be; Terminal and iTerm2
renders it as width 1, while kitty renders it as width 2. This is
unaffected by fish_emoji_width because the flag does not have an assigned
codepoint, it is a pair of codepoints.
The regional indicators are marked as "neutral" in EastAsianWidth.txt which
means they conceptually have width 1. So two of them have width 2. So now
we assume that flags are rendered as width 2.
This fixes#7237, for terminals that render flags as width 2 (but not 1,
unfortunately, which includes iTerm2 and Terminal.app).
fish_color_match is a variable which controls syntax highlighting for
matching quotes and parens, but only with interactive `read` with shell
highlighting disabled. It seems unlikely that anybody cares about this.
builtins output to stdout and stderr via io_streams_t. Prior to this fix, it
contained an output_stream_t which just wraps a buffer. So all builtin output
went to this buffer (except for eval).
Switch output_stream_t to become a new abstract class which can output to a
buffer, file descriptor, or nowhere. This allows for example `string` to stream
its output as it is produced, instead of buffering it.
Add a helper function to check if the user is root. This function can be
useful for the prompts for example. Modify the prompts made root checked
to use the function instead. Add also the support of Administrator like
a root user.
Fixes: #7031
This makes binding \cz possible.
We already ignore the SIGTSTP signal it sends, so until now it was useless.
(also STOP and START for good measure, but since we disable flow
control in fish anyway these already shouldn't have been sent)
Fixes#7152
Prior to this fix, fish would attempt to resize the terminal via
TIOCSWINSZ, which was added as part of #3740. In practice this probably
never did anything useful since generally only the tty master can use
this. Remove the support and note it in the changelog.
Prior to this change, if the user's prompt was wider than the terminal, we
would reduce it to just `> `. With this change, attempt to truncate the
prompt.
For each line of the prompt, calculate its width. If the width exceeds
COLUMNS, prepend ellipsis to that line, and start removing characters
until it fits. Escape sequences are skipped.
Fixes#904
We use sphinx with rst for our documentation, and github supports rst
here, so it seems weird to have markdown just for these.
It also allows us e.g. to include the CHANGELOG in the docs without
requiring another build dependency.
