net_tools, which provides `ifconfig` and `netstat`, among other things,
has last been updated in 2013. This means `ifconfig` on linux is
basically dead.
Instead of ifconfig, use `ip` (from iproute2), which is much more powerful and
provides a much more annoying commandline syntax.
Instead of netstat, just look at /sys/class/net.
fish_user_key_bindings is the user's, and they should know if they want
vi-ish bindings or emacs-ish (or nano-ish). If they want to define
multiple, they can also do that (e.g. via checking what
$fish_key_bindings is set to).

Erase startup cnf-handler early
Simplifies the code a bit - in particular it removes the special-casing
from the startup handler.

Make overriding cnf-handler work
Do this by renaming the __fish_command_not_found_handler used during
startup to __fish_startup_command_not_found_handler. That allows us to
check if __fish_command_not_found_handler has been defined and skip the
setup of the normal one.
Now disabling cnf-handling can be done via defining an empty
__fish_command_not_found_handler in config.fish
This adds a special colorscheme and prompt function guaranteed to work
on a VT and activates them automatically if $TERM = "linux".
set_color is overridden to only allow the 8 colors VTs have (under the
assumption those are always the same) and the color variables are
shadowed with global ones so they don't pollute our nice capable terms.
This used to be a function because we didn't have complete -w
Use that and it becomes a bit simpler.
This also simplifies the code in a few other ways (like removing a
useless-use-of-cat)
and adds comments about a few edgecases.
changed `function __trap_handler_EXIT --on-exit %self` to `function __trap_handler_EXIT --on-process-exit %self`
I'm guessing the on-exit syntax was from an older version? Trapping EXIT with that syntax caused errors.
The following behaviour is added:
- an empty pushd exchanges the top two directories in the stack;
- pushd +<n> rotates the stack so that the n-th directory (counting from the left of the list shown by dirs, starting with zero) is at the top;
- pushd -<n> rotates the stack so that the nth directory (counting from the right of the list shown by dirs, starting with zero) is at the top.
1. When run with no arguments, make abbr do the equivalent
of `abbr --show`
2. Enable "implicit add", e.g. `abbr gco git checkout`
3. Teach `abbr --show` to not use quotes for simple cases
4. Teach abbr to output -- when the abbreviation has
leading dashes
Add some basic tests to abbr too.
Add a new function fish_mode_prompt which (if it is defined) has its output
prepended to the left prompt. Rather than replacing the prompt wholesale, make
fish_vi_mode enable this function by setting a variable __fish_vi_mode. This
enables vi mode to interoperate nicely with custom prompts. Users who want
to change how the mode is reported can either redefine this function or
erase it entirely. Fixes#1988.
- Add four new functions: forward-bigword, backward-bigword,
kill-bigword, backward-kill-bigword
- Add new enum move_word_style_whitespace and related state machine
method
- Change vi key bindings to operate on bigwords: B, gE, W, E, dW, diW,
daW, dE, dB, dgE, cW, ciW, caW, cE, cB, cgE, yW, yiW, yaW, yE, yB,

Notification is sent using an OSC 777 escape sequence as described at
http://known.phyks.me/2014/local-notifications-for-weechat-and-urxvt.
The specific notification is crafted to match that emitted by bash
when running under Fedora 22 with the "vte-profile" RPM installed.
See the code for "__vte_prompt_command" starting at
http://pkgs.fedoraproject.org/cgit/vte291.git/tree/vte291-command-notify.patch#n307
to see exactly what bash produces. My approach is, however, a bit
more paranoid about control characters embedded in commands.
Gnome-terminal 3.16 responds to this escape sequence by posting a
desktop notification if the containing terminal window does not have
focus. This lets the user know that a long-running background command
has completed. Job notification is promoted as a Fedora 22 feature
(http://fedoramagazine.org/terminal-job-notifications-in-fedora-22-workstation/),
so it would be good for fish users to be benefit from it.
Conversely, anyone who does not want this feature can use "functions
--erase __notify_vte_command_completed" to turn it off.
With the fix for #365, fish_command_not_found event handlers
receive the command and all of its arguments. But commands
like /usr/lib/command-not-found expect only the command name.
So when invoking an external command, just pass the command
name, not all of the arguments.
In 73f344f41b, we allowed autoloaded functions to be deleted.
For some reason, funcsave immediately deletes the function it
creates. This previously did very little, since the function would
immediately be re-autoloaded, but with the fix for 73f344f41b
the function gets tombstoned. So the effect is that funcsave
makes the function disappear! This simply removes the erase call,
which dates back to fish 1.x.
It seems that `ul` can't handle the escape sequences for bold text that `nroff` generates on my system. Fixed by either removing `| ul`, or adding `-c` to the `nroff` command.
Needs testing for old (OSX?) versions of nroff.
Support for space-delimited abbreviations was added to the expansion
parser in fbade198; this commit extends that support to the user-facing
tools, and documents the space-separated behaviour. Equals-delimited
abbreviations are expected to be removed before the next release.
Work on #731.
There is no CTRL-C handler for the default mode in the vi bindings. This makes it difficult to say "never mind" and start a new command line like you can do in bash's vi mode.
There were CTRL-C handlers for insert and visual modes that go back to default mode, but nothing happens in default mode. I copy-pasted the CTRL-C handler from the default key bindings file.
(Ideally, the behaviour of git could be implemented: pipe the input
through a pager iff the length is > window size and in interactive
mode).
Closes#1076.
The terminal width magic that __fish_print_help learned doesn't help
when builtin_print_help runs it in a subshell. Instead, add an
undocumented --tty-width flag to __fish_print_help that's used to pass
the terminal width.
As a result of this rewrite, the output now:
* Expands to fit the terminal width, like `man` does
* Preprocesses the manpage with `tbl` just in case, since `man` does
this, even though I doubt any fish manpages use `tbl` formatting.
* Handle bold/underline with the `ul` command as it was designed for
instead of trying to fake it with `sed`.
* Compresses blank lines as `man` does with the default `less -is`
pager.
The usage is still the same, but it's a lot more robust, and also no
longer assumes $fish_user_abbreviations must be a universal variable.
This also fixes the unexpected error output when calling `abbr -a` with
no existing abbreviations.
Calling `abbr -a` with an abbreviation that already exists now silently
overwrites the abbreviation, just like `function` and `bind` do, instead
of complaining.
# The first commit's message is:
Simplify default fish_prompt
No need for the set_color caching now that it's a builtin.
Also simplify the 3 classic prompts in fish_config's sample_prompts set.
Remove comment that AFAICT is not true anymore.
Ensure someone setting __fish_active_key_bindings as a universal
variable doesn't screw up the initial keybinding load.
Apparently, in zsh, Meta+H can be used to display the manpage for
the current command. This commit adds this zsh feature to fish shell.
The F1 keybinding is left, although it's now secondary according to
fish help, as some terminal emulators don't let the user press F1 key.
Setting a non-existant path component to PATH logs an error to stderr.
This is not appropriate for non-interactive temporary modifications,
like the one done by the `sudo` completion helper function.
The new --wraps functionality was breaking aliases of the form
`alias foo='bar baz'`. That is, aliases where the body is multiple
words. Extract the first word of the body and use that instead.
Use better errors for aliases with no name or no body.
Add the --wraps option to 'complete' and 'function'. This allows a
command to (recursively) inherit the completions of a wrapped command.
Fixes#393.
When evaluating a completion, we inspect the entire "wrap chain" for a
command, i.e. we follow the sequence of wrapping until we either hit a
loop (which we silently ignore) or the end of the chain. We then
evaluate completions as if the wrapping command were substituted with
the wrapped command. Currently this only works for commands, i.e.
'complete --command gco --wraps git\ checkout' won't work (that would
seem to encroaching on abbreviations anyways). It might be useful to
show an error message for that case.
The commandline builtin reflects the commandline with the wrapped
command substituted in, so e.g. git completions (which inspect the
command line) will just work. This sort of command line munging is
also performed by 'complete -C' so it's not totally without precedent.
'alias will also now mark its generated function as wrapping the
'target.
Currently fish doesn't recognize toor as special. However, it's likely
that on BSD systems, fish shell will be used on toor, not on root (toor
is an intentionally existing account to use more advanced shell on, like
shell).
Use `functions -q` instead of searching the `functiosn -na` list for the
provided word. This may result in an automatically-loaded function being
sourced, but that happens anyway with the default output.
This change means the results of `test -q foo` can be relied upon to
indicate whether `foo` can actually be invoked. Previosly, if `foo` was
the name of an automatically-loaded function file but did not actually
define a function `foo`, and there was no execuable `foo`, then `type -q
foo` would lie and say `foo` can be invoked when it can't.
The --quiet flag is useful when only the exit status matters.
Fix the documentation for the -t flag to no longer claim that `type` can
print "keyword", as it never does that.
Stop printing a blank line for functions/builtins when the -p flag has
been passed. It's just not useful.
Track whether -a and -f have been supplied separately. That way both
`type -a -f command` and `type -f -a command` behaves correctly, as does
`type -a -f foo` where there are multiple executables named `foo` in the
$PATH.
Stop using getopt to parse flags. It's far more expensive than
necessary, and results in long flags not being parsed on OS X. This also
allows args starting with - after the options list to be properly
interpreted as a value to test.
Print the error message to stderr as is appropriate.
Use the new `command -p` functionality when the -a flag has not been
provided (`command` does not have any equivalent to the -a flag),
instead of using `which`. This is faster and also avoids any possible
disagreement between `which` and what fish thinks is valid.
Stop testing every path to see if it's executable, that test has already
been done by `which` or `command -p`.
The end result is `type -P ls` is roughly 250% faster, according to
profiling, on my OS X machine.
* use $XDG_CACHE_HOME for __fish_print_packages completion caches
* when starting fishd, redirect fishd output to /dev/null, not a
predictable path
Fix for CVE-2014-3219.
Closes#1440.
Fix for CVE-2014-2906.
Closes a race condition in funced which would allow execution of
arbitrary code; closes a race condition in psub which would allow
alternation of the data stream.
Note that `psub -f` does not work (#1040); a fix should be committed
separately for ease of maintenance.
Closes#1437
At some point the non-verbose, non-informative variant of the prompt
(e.g. the variant that looks like the bash prompt) was modified to try
and show the behind/ahead counts the same way the informative prompt
does. Besides being wrong, it also didn't work because behind/ahead
weren't defined.
Previously, fish's command_not_found handler would be installed in
__fish_config_interactive. Errors that occured early in startup (e.g. in
config.fish) or in non-interactive mode would therefore not be reported.
With this change, fish now exposes its default cnf handler as
__fish_default_command_not_found_handler . config.fish then installs a
cnfh that invokes the default. When fish goes interactive, the initial
cnfh is overwritten with a fancier one, that may in turn fall back to
invoking the default.

Fix cnf handler for Suse and Fedora
fixes#1208
Presently, `isatty` only works on a handful of keywords. Here it
is rewritten to be able to take any path, device or fd number as
an argument, and eliminates errors printed to stdout.
Per discussion in #1228, using `builtin test -c` within a pipe to
test special file descriptors is not viable, so this implementation
specifcially uses `command test`. Additionally, a note has been
added to the documentation of `test` regarding this potential
aberration from the expected output of the test utility under the
'Standards' section.
Comment out 'o' binding
Add '['/']' bindings to navigate current token history
Fix 'P' to paste indeed
Add "*P/"*p to insert current selection clipboard using xsel
These options will be passed to the bind command.
Now it's possible to call
fish_default_key_bindings -M insert
to set all original bindings to the insert mode
The following normal mode bindings are added:
o, I, A, gg, G, g^, g$, x, X, backspace, d*, D, s, S, c*, C, ~, gu,
gU, J, K, y*, Y, p, P
I was not able to add binding for 'O'
dd now deletes the whole line as vim, while D deletes the line to the
end. c, s, y act the same way
Continuation of https://github.com/fish-shell/fish-shell/pull/1195/.
Removes use of --delimiter and --fields with cut(1) as these are GNU
extensions.
Note that a number of completions use these options, but as they are
only for GNU/Linux-specific tools have remained unmodified.
There is no need to explicitly check for two arguments and set --bold.
Instead the user can simply "set __fish_git_prompt_color_flags --bold
red".
The current check violates the expectation set by the documentation
that you can use any set_color argument as the current code interprets
"--bold red" as "--bold --bold" instead.
Plus, by passing the full contents of the variable directly, the user
can do more adventurous things like set the background as well.
git.git's git-prompt may not contain a configurable prefix, but it
does display a space before the upstream information when displaying
verbose information. Rather than using a space always or never,
default to a space whenever verbose is in showupstream.
Adds a "name" option to __fish_git_prompt_showupstream that shows an
abbreviated branch name when the upstream type is verbose.
Based on git.git 1f6806c: git-prompt.sh: optionally show upstream
branch name
Closes#479 by piping STDERR to /dev/null.
Also does much less manipulation of the package list; there are no
packages in any of the archives containing the names that are stripped
out as far as I can see.
