`exec` now exhibits the same behavior as `exit` and prompts the user to
confirm their intention to end the current process if there are
background jobs running. Running `exec` again immediately thereafter
will force the exec to go through.
Additionally, background jobs are reaped upon exec to prevent process
leaking (same as `exit`).
This changes the behavior of builtin math to floating point by default.
If the result of a computation is an integer, then it will be printed as an
integer; otherwise it will be printed as a floating point decimal with up to
'scale' digits past the decimal point (default is 6, matching printf).
Trailing zeros are trimmed. Values are rounded following printf semantics.
Fixes#4478
Utilized the `--install` flag added in commit #8c09d6e.
Limit `eopkg remove/autoremove/check ...` completions to installed packages.
Limit `eopkg install/upgrade/info ...` completions to available packages.
Added a new flag `--installed` via `argparse` to `__fish_print_packages`
which indicates that only installed packages should be listed.
TODO: Other non-debian/apt platforms should take advantage of this flag/
behavior as well.
I'm not sure what was up with the old completions,
`$__fish_service_commands` is not set anywhere and completions for the
command (not the service) were not being generated on my machine.
This partially reverts 5b489ca30f, with
carets acting as redirections unless the stderr-nocaret flag is set.
This flag is off by default but may be enabled on the command line:
fish --features stderr-nocaret
Selectively reverts 156d4fb9b9.
`all-the-package-names` is still used to generate completions for `npm`
if it is installed, but it is not manually installed nor updated. It is
now the user's responsibility to do both, and it must be installed
globally.
This relies on the new `read --line/-L` support as an entire parser for
the output of `./configure --help` was written in fishscript. Also
doesn't work without 72f32e6d8a7905b064680ec4b578c41dea62bf84.
The completion script is slow... a function of both the autotools
configure script itself being written in a shell script combined with a
fishscript output parser.
fish's own `./configure --help` takes around 350ms to execute, while
`__fish_parse_configure ./configure` (which runs that behind the scenes)
takes around 660ms to run, all-in-all - a not insignificant overhead.
Output can be cached (based off of ./configure hash or mtime) in the
future if this is a big deal.
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
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.
Removed misleading statement about read requiring an argument, as the
note about read's new behavior when no arguments are provided covers
that and is less confusing.
Now parses package.json and uses results to provide a list of possible
completions to `yarn remove`. There may be other subcommands that could
benefit from this.
Could have parsed yarn output, but yarn is slow and packages.json format
is generally standard since it's machine-generated json.
This enables some limited use of arguments for wrapping completions. The
simplest example is that complete gco -w 'git checkout' now works like
you would want: `gco <tab>` now invokes git's completions with the
`checkout` argument prepended.
Fixes#1976
`argparse`, `read`, `set`, `status`, `test` and `[` now can't be used
as function names anymore.
This is because (except for `test` and `[`) there is no way to wrap these properly, so any
function called that will be broken anyway.
For `test` (and `[`), there is nothing that can be added and there
have been confused users who created a function that then broke
everything.
Fixes#3000.
The previous attempt to support newlines after pipes changed the lexer to
swallow newlines after encountering a pipe. This has two problems that are
difficult to fix:
1. comments cannot be placed after the pipe
2. fish_indent won't know about the newlines, so it will erase them
Address these problems by removing the lexer behavior, and replacing it
with a new parser symbol "optional_newlines" allowing the newlines to be
reflected directly in the fish grammar.
Properly escape literal tildes in tab completion results. Currently we
always escape tildes in unquoted arguments; in the future we may escape
only leading tildes.
Fixes#2274
This special cases expansion of $history variables, so that slicing
history no longer needs to construct the entire history array. Speedup
is around 100x in my test.
Fixes#4650
Prior to this fix, if the user typed normal characters while the
completion pager was shown, it would begin searching. This feature was
not well liked, so we are going to instead just append the characters as
normal and disable paging. Control-S can be used to toggle the search
field.
Fixes#2249
Some dotfile users like to add directories to PATH that point at
non-existent directories (because those directories exist on other
machines). Stop warning in that case, unless those directories contain
a colon, in which case it's probably a user error.
Prior to this fix, a "bare variable" in math like 'x + 1' would be
looked up in the environment, i.e. equivalent to '$x + 1'. This appears
to have been done for performance. However this breaks the orthogonality
of fish; performance is not a sufficient justification to give math this
level of built-in power, especially because the performance of math is
not a bottleneck. The implementation is also ugly.
Remove this feature so that variables must be prefixed with the dollar
sign and undergo normal variable expansion. Reading 'git grep' output
does not show any uses of this in fish functions or completions.
Also added to changelog.

Instead of treating the search term as a literal string to be matched
treat it as a glob. This allows the user to get a more useful set of
results by using the `*` glob character in the search term.
Partial fix for #3136
* Hoist `for` loop control var to enclosing scope
It should be possible to reference the last value assigned to a `for`
loop control var when the loop terminates. This makes it easier to detect
if we broke out of the loop among other things. This change makes fish
`for` loops behave like most other shells.
Fixes#1935
* Remove redundant line
Using a read-only variable like `status` as a for loop control variable
has never worked. But without this change you simply get non-sensical
behavior that leaves you scratching your head in puzzlement. This change
replaces the non-sensical behavior with an explicit error message.
Fixes#4342
The `react_to_variable_change()` function is called whenever a fish var
is set. Even as a consequence of statements like `for x in a b c`. It is
therefore critical that that function be as fast as possible. Especially
when setting the var doesn't have any side-effects which is true something
like 99.9999% of the time.
This change reduces the overhead of `react_to_variable_change()` to
unmeasurable levels. Making the synthetic benchmark in issue #4341
36% faster.
Fixes#4341
This makes command substitutions impose the same limit on the amount
of data they accept as the `read` builtin. It does not limit output of
external commands or builtins in other contexts.
Fixes#3822
Rewrite the `abbr` function to store each abbreviation in a separate
variable. This greatly improves the efficiency. For the common case
it is 5x faster. For pathological cases it is upwards of 100x faster.
Most people should be able to unconditionally define abbreviations in
their config.fish without a noticable slow down.
Fixes#4048
Introduce a -k/--keep-order switch to `complete` that can be used to
prevent fish from sorting/re-ordering the results provided by a completion
source.
In addition, this patch does so without doing away with deduplication
of completions by introducing a new unique_unsorted(..) helper function
that removes duplicates in-place without affecting the general order of
the vector/container.
Note that the code now uses a stable sort for completions, since the
behavior of is_naturally_less_than as of this patch now means that the
results are not necessarily _actually_ identical just because that function
repeatedly returns false for any ordering of any given two elements.
Fixes#361
This completes the refactoring of the `set` builtin. It also removes a
seemingly never used feature of the `set` command. It also eliminates all
the lint warnings about this module.
Fixes#4236
Fish 2.6.0 introduced a regression that keeps setting
`fish_escape_delay_ms` as a uvar from working. This also fixes a related
problem: callbacks generated from the initial loading of universal vars
were not being acted on.
Fixes#4196
We've needed a fishy way to parse flags and arguments given to scripts
and functions for a very long time. In particular a manner that provides
the same behavior implemented by builtin commands. The long term goal is
to support DocOpt. But since it is unclear when that will happen so this
implements a `argparse` command. So named as homage to the excellent
Python module of the same name.
Fixes#4190
The count command should not treat any flag specially. Not even `-h` and
`--help`. It should simply return a count of the number of arguments it
received.
Fixes#4189
The `read` command `-m` and `--mode-name` vars are now deprecated and do
nothing other than result in a warning message. The `read` command now
honors the `FISH_HISTORY` var that is used to control where commands are
read from and written to. You can set that var to the empty string to
suppress the use of both history files. Or you can set it to a history
session ID in which case that will limit the `read` history that is
available.
Fixes#1504
We need a way to encode arbitrary strings into valid fish variable
names. It would also be nice if we could convert strings to valid URLs
without using the slow and hard to understand `__fish_urlencode` function.
In particular, eliminating the need to manipulate the locale.
Fixes#4150
This implements `status is-breakpoint` that returns true if the current
shell prompt is displayed in the context of a `breakpoint` command.
This also fixes several bugs. Most notably making `breakpoint` a no-op if
the shell isn't interactive. Also, typing `breakpoint` at an interactive
prompt should be an error rather than creating a new nested debugging
context.
Partial fix for #1310
