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).
no-op function for compatibility with sh, bash, and others.
Often used to insert a comment into a chain of commands without having
it eat up the remainder of the line, handy in Makefiles.
In similar vein to how fish_default_key_bindings works, parameters
passed to the function are automatically passed to bind upstream.
Additionally, -s is automatically added if no parameters had been
specified to prevent startup error messages. See 46d1334.
Closes#4494
Can be used to retrieve a list of parent paths, useful for searching
ancestors recursively via their absolute paths. Paths are returned from
deepest to shallowest, starting from the path passed in. Paths are not
validated for performance reasons. (Usually the input to
__fish_parent_directories would be (pwd) or (dir $file).)
* Add eopkg support
Add support for eopkg in __fish_print_packages function, and
add new completion eopkg.fish in share/completions
* Sorry for the empty file
* Sorry for the empty file again
* Use builtin function for checking subcommand and options
* Fix description
* Use string function to replace grep and cut
* Add completion for search command
This was caused by it prepending "-s" to argv always,
and later checking $argv[1].
As it turns out, that is kinda superfluous, so we can just add "-s" to
the `bind` calls.
Also adjust the tests so the vi-bindings are enabled via the function,
which would have caught this.
Fixes#4494.
The previous hack used to work around an OS X issue/bug where launching
a URL with a #fragment appended would drop the fragment by using
`osascript` does not seem to work any more. Append the section name as a
query string (in addition to, not instead of #section) and then use some
basic javascript appended to the user doc HTML template to parse that
and jump to the correct section (if the section was dropped).
Closes#4480
E.g. if "foo" is in CDPATH, and both "foo/bar" and "./bar" exist, `cd
bar` will go to ./bar.
The completions described "bar" as going to "foo/bar" ("CDPATH foo").
This fixes it by checking for ./bar's existence.
See #4475.
This silences binding errors due to keys not found in the current
termcap config in the default fish bindings.
Closes#4188, #4431, and obviates the original fix for #1155
It was necessary to re-implement builtin_bind as a class in order to
avoid passing around the options array from function to function and
as adding an opts parameter to `get_terminfo_sequence` would require
otps to be passed to all other builtin_bind_ functions so they could, in
turn, pass it to `get_terminfo_sequence`.
This
- Offers more candidates
- Is more reactive (it'll always incorporate "--state=" and "--type="
- Is faster (about 800ms to about 120ms)
- Needs fewer function files
All __fish_systemctl_* functions except __fish_systemctl_services have
been removed.
Decided to move doc_src/fish.lss to share/lynx.lss, which just makes
more sense all around. Accordingly, now using {$__fish_datadir} instead
of {$__fish_help_dir} in help.fish.
Makefile now installs the custom lss on make install
Lynx uses a very naïve method of applying styles to HTML elements by
hashing the element type and the class name to generate a map of
hash:style. After the hash is calculated, Lynx does not go back and
check whether or not the actual string values match the LSS properties.
See the following links on the Links mailing list:
* http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00037.html
* http://lists.gnu.org/archive/html/lynx-dev/2015-12/msg00039.html
This patch copies the default Lynx stylesheet but removes highlighting
and other styles that would result in unreadable text (due to not enough
contrast with the background color), and if the `help` builtin detects
that the best web browser to use is Lynx, it instructs it to use this
modified stylesheet.
If the $DISPLAY environment variable is not set, xdg-open should not be
used to load the web browser. Just because it is installed does not mean
that the user exclusively runs in an X session.
Needed for Lynx detection to work around #4170
Thanks to @ThomasAH, as per #4378. Tested on many platforms (OS X,
FreeBSD, Linux, and Solaris). Works with IPv4 and IPv6 as well as
host names and loopback addresses.
Drawing prompt in repo with text=auto attribute and mixed line endings in files was spawning crlf conversion warnings to terminal from unsilenced stderr of git diff
This flag was only documented for a few weeks before being renamed
`--show-time` and has been deprecated for a long time. Fish 3.0 is a good
opportunity to remove it.
* Implement `history search --reverse`
It should be possible to have `history search` output ordered oldest to
newest like nearly every other shell including bash, ksh, zsh, and csh.
We can't make this the default because too many people expect the
current behavior. This simply makes it possible for people to define
their own abbreviations or functions that provide behavior they are
likely used to if they are transitioning to fish from another shell.
This also fixes a bug in the `history` function with respect to how it
handles the `-n` / `--max` flag.
Fixes#4354
* Fix comment for format_history_record()
Using bare vars is more efficient because it makes the builtin `math`
expression cache more useful. That's because if you prefix each var with
a dollar-sign then the fish parser expands it before `math` is run.
Something like `math x + 1` can be cached since the expression is the
same each time it is run. But if you do `math $x + 1` and x==1 then you're
effectively executing `math 1 + 1`. And if x==2 the next time then you're
running `math 2 + 1`. Which makes the expression cache much less effective.
Remove our `math` function that wraps `bc`. Our math builtin is now good
enough that it can be the default implementation.
Another step in resolving #3157.
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
The recent change to switch `psub` to use `argparse` caused it to use
a fifo by default because it inadvertently fixed a long standing bug in
the fish script. This changes the behavior back to `psub --file` being
the default behavior and introduces a `--fifo` flag. It also updates the
documentation to make it clearer when and why `--fifo` mode should not
be used.
Fixes#4222
While updating the `history` function to use `argparse` I realized it is
useful to define an option that can be used in three ways. First by
using the short flag; e.g., `-n NNN`. Second by using the long flag;
e.g., `--max NNN`. Third, as an implicit int flag; e.g., `-NNN`. This
use case is now supported by a spec of the form `n#max`.
A recent regression to the `alias` command points out the need for more
unit tests of its behavior. I also decided to use it as an opportunity
to normalize the output of just `alias` to list aliases.
The previous change to use `argparse` for parity with every other
builtin and function introduced a regression. Invocations that start
with a negative number can fail because the negative value looks like an
invalid flag.
