This is essentially the inverse of `string pad`.
Where that adds characters to get up to the specified width,
this adds an ellipsis to a string if it goes over a specific maximum width.
The char can be given, but defaults to our ellipsis string.
("…" if the locale can handle it and "..." otherwise)
If the ellipsis string is empty, it just truncates.
For arguments given via argv, it goes line-by-line,
because otherwise length makes no sense.
If "--no-newline" is given, it adds an ellipsis instead and removes all subsequent lines.
Like pad and `length --visible`, it goes by visible width,
skipping recognized escape sequences, as those have no influence on width.
The default target width is the shortest of the given widths that is non-zero.
If the ellipsis is already wider than the target width,
we truncate instead. This is safer overall, so we don't e.g. move into a new line.
This is especially important given our default ellipsis might be width 3.
pipenv switched from older click-completion package to new built-in completions
from click framework in v2021.11.9.
This command achieves compatibility with both, older and more recent versions.
`cargo search` can be used to quickly get crates matching a search string, so we
can pass the current token for first-arg completions to `cargo add` and `cargo
install` to `cargo search` to look up matches.
`cargo search` doesn't restrict itself to (nor prioritize for) prefix matches,
while fish will only display prefix matches (for dynamically generated
completions) so it's perfectly possible for `cargo search foo` to return 20
results none of which will successfully result in a completion, but for a
further-narrowed completion of `cargo install foob^I" to then result in
completions because `cargo search` ended up returning a prefix match for `foob`
while it didn't for `foo`.
The only other oob cargo subcommand that takes a crate name (that isn't the name
of a crate specified in `Cargo.toml`) is `cargo search` but there's no point in
providing completions to that... I think (it's possible to search for crate
"foo" in order to get its latest version number rather than its name, but I'm
not sure that's worth supporting).
This expands completions of `cargo^I` to list any commands named `cargo-xxx` as
cargo subcommands invokable as `cargo xxx` in addition to the default oob
subcommands cargo ships with.
(This is very similar to how git allows users to shim their own subcommands.)
NOTE: This would stay even after cargo someday moves to clap and generates or
even ships/installs an official machine-generated `cargo.fish` completions
script.
The old way of generating cargo completions no longer work, so we need
to manually maintain the completions until clap completions support[1].

When selecting items in the pager, only the latest of those items is kept
in the edit history, as so-called transient edit. Each new transient edit
evicts any old transient edit (via undo).
If the pager is closed by a command that performs another transient edit
(like history-token-search-backward) we thus inadvertently undo (= remove)
the token inserted by the pager. Fix this by closing a transient edit
session when closing the pager. Token search will start its own session.
Fixes#9160
strncpy will fill the entire buffer with NUL.
In this case we have a 128 byte buffer and write "empty" - 5 bytes -
into it.
So now instead of writing 6 bytes it'll write 128 bytes. Especially
wasteful because we already did memset before
This fixes a crash when you open the history pager and then do
history-token-search-backward (e.g. alt+. or alt-up).
It would sometimes crash because the `colors.at(i)` was an
out-of-bounds access.
Note: This might still leave the highlighting offset in some
cases (not quite sure why), but at least it doesn't *crash*, and the
search generally *works*.
This used `realpath -eq`, which for GNU realpath:
1. Suppresses "most error messages" (-q)
2. Requires that all parts exist (rather than allowing the last not
to)
Since we don't actually need a real path here, just filter.
Fixes#9099
* added completions for sad and added note in changelog
* ran fish_indent on completion file
* split -h and --help into two distinct completion options
This was written while we changed how our synopses are formatted, so
we missed adding a "synopsis" marker to it.
The tokenizer here is a bit cheesy, so we can't mark continuation
lines with a "\", and we also can't mark the general options with a
":=". Tbh that's not a big deal.
Fixes#9154
This starts two sleep processes and expects them to be killed on
SIGHUP.
Unfortunately, if this ever fails the second run will also fail
because it'll see the old sleep still lying around (because it'll run
for 130 seconds).
So, what we do is:
1. Keep the pids for these specific sleeps
2. Check if any of them are still running (and only fail for them)
3. Kill them from python

This reverts commit 3e556b984c.
Revert "Further fix the issue and add the assert that'd have prevented it."
This reverts commit 056502001e.
Revert "Fix actual issue with allow_use_posix_spawn."
This reverts commit 85b9f3c71f.
Revert "Stop using posix_spawn when it is not allowed"
This reverts commit 9c896e1990.
Revert "don't even set up a fish_use_posix_spawn handler if unsupported"
This reverts commit 8b14ac4a9c.
Commit 8b14ac4a9c started using
posix_spawn even if allow_use_posix_spawn() returns false. Stop doing
that.
This may be reproduced with:
./docker/docker_run_tests.sh ./docker/centos7.Dockerfile
as centos7 has a too-old glibc.
Let's hope this doesn't causes build failures for e.g. musl: I just
know it's good on macOS and our Linux CI.
It's been a long time.
One fix this brings, is I discovered we #include assert.h or cassert
in a lot of places. If those ever happen to be in a file that doesn't
include common.h, or we are before common.h gets included, we're
unawaringly working with the system 'assert' macro again, which
may get disabled for debug builds or at least has different
behavior on crash. We undef 'assert' and redefine it in common.h.
Those were all eliminated, except in one catch-22 spot for
maybe.h: it can't include common.h. A fix might be to
make a fish_assert.h that *usually* common.h exports.
Fixed a line or two tripped IWYU asserts about visibility
when doing e.g. a private -> public mapping but the visibility
it came up with was identical. Like the <iosfwd> to <string>
mapping, it was defined as private -> public but they're both
"public".
Added a whole bunch of lines necessary to get sane/correct
reccomendations from current IWYU on clang 10 on macOS Ventura.
Incrementally I manually added these as needed while going through
each line change IWYU wanted in each file.
