This brings back expansion of `%n` where `n` is a job id, but not as a
general parser syntax. This makes `jobs -p %n` work, which can be used
as part of the job control command chain, i.e.
```
cat &
fg (jobs -p %1)
```
fg/bg/wait can either be wrapped in a function to call `jobs -p` for
`%n` arguments, or they can be updated to take `%n` arguments
themselves.
The order of this list does not need to be strictly maintained any
longer.
Benchmarked with `hyperfine` as follows, where `bench1` is the existing
approach of binary search and `bench2` is the new unordered_set code,
(executed under bash because fish would always return non-zero). The
benchmark code checks each argv to see if it is a builtin keyword (both
return the same result):
```
hyperfine './bench1 $(shuf /usr/share/dict/words)' './bench2 $(shuf /usr/share/dict/words)'
Benchmark #1: ./bench1 $(shuf /usr/share/dict/words)
Time (mean ± σ): 68.4 ms ± 3.0 ms [User: 28.8 ms, System: 38.9 ms]
Range (min … max): 60.4 ms … 75.4 ms
Benchmark #2: ./bench2 $(shuf /usr/share/dict/words)
Time (mean ± σ): 61.4 ms ± 2.3 ms [User: 23.1 ms, System: 39.8 ms]
Range (min … max): 58.1 ms … 67.1 ms
Summary
'./bench2 $(shuf /usr/share/dict/words)' ran
1.11x faster than './bench1 $(shuf /usr/share/dict/words)'
```
Now the description includes the variable scope, `set [-e] -[Ugl]`
completions only provide variables matching that scope, and completions
that shouldn't be modified are hidden from the user. Completions that
are often modified but rarely unset (`fish_*` variables) are omitted
from `set -e` completions.
A new helper function `__fish_seen_argument` has been added that makes
it easy to only provied completions for a specific flag.
Launch `cmd.exe /c "start URL"` under WSL for both `fish_config` and
`help`. This works around #4299 but does not address the underlying
issue (#1132).
Prior to this fix, the fish universal variables file claimed that
changes to it would be overwritten. This no longer true and has not
been true for a long time. Remove that warning.
This switches the universal variables file from a machine-specific
name to the fixed '.config/fish/fish_universal_variables'. The old file
name is migrated if necessary.
Fixes#1912
This removes the caret as a shorthand for redirecting stderr.
Note that stderr may be redirected to a file via 2>/some/path...
and may be redirected with a pipe via 2>|.
Fixes#4394
The previous commit caused the tests to fail since env_remove() was
returning a blanket `!0` when a variable couldn't be unset because it
didn't exist in the first place. This caused the wrong message to be
emitted since the code clashed with a return code for `env_set()`.
Added `ENV_NOT_FOUND` to signify that the variable requested unset
didn't exist in the first place, but _not_ printing the error message
currently so as not to break existing behavior before checking if this
is something we want.
Variables set in if and while conditions are in the enclosing block, not
the if/while statement block. For example:
if set -l var (somecommand) ; end
echo $var
will now work as expected.
Fixes#4820. Fixes#1212.
fish reads paths out of /etc/paths.d. Prior to adbaddf it did
this on every shell invocation; with adbaddf it does so on only login
shells. This change wasn't justified so let's revert this behavior.
Currently, there are two possibilities for holes in the background:
- When there are two candidates with the same meaning (a long and a
short option or two candidates with the same description)
- When a candidate does not have a description (meaning the color
won't continue after it)
This changes both so the background just goes on.
In addition, it avoids making the background multiple times.
Fixes#4866.
The official fish documentation makes no mention of how `string split`
treats empty tokens, e.g. splitting 'key1##key2' on '#' or (more
confusingly) splitting '/path' on '/'. With this commit, `string split`
now has an option to exclude zero-length substrings from the resulting
array with a new `--no-empty/-n`. The default behavior of preserving
empty entries is kept so as to avoid breakage.
The two unicode glyphs used to represent missing new lines and redacted
characters for secure entry are both not present in the glyph tables of
the default font under Windows (Consolas and Lucida Console), use an
alternative glyph instead.
The "return" symbol is replaced with a pilcrow (¶) and the "redacted
character" symbol is replaced with a bullet (•). Both of these are
well-defined in almost all fonts as they're very old symbols. This
change only takes place if -DWSL is supplied by the build toolchain.
Note: this means a Windows SSH client connecting to a fish remote
instance on a non-Windows machine will still use the (unavailable)
default glyphs instead.
