It removed $KONSOLE_PROFILE_NAME and added $KONSOLE_VERSION.

This reverts commit 535845861a.
That commit introduced a bug where tab-completing commands no longer
prints their descriptions, unless there is an exact match.
When this switched over from directly piping commandline to storing
its output and using printf, I inadvertently always added a trailing
newline. That's probably annoying.
Note that this will now always *remove* a trailing newline (because
the command substitution does). That will barely make a
difference (because trailing newlines are quite unusual in the
commandline) and will probably feel better than keeping it - we could
even make a point of removing trailing whitespace in general.
Fixes#6927
This updates the behavior of tilde to match the behavior found in vim.
In vim, tilde toggles the case of the character under the cursor and
advances one character. In visual mode, the case of each selected
character is toggled, the cursor position moves to the beginning of
the selection, and the mode is changed to normal. In fish, tilde
capitalizes the current letter and advances one word. There is no
current tilde command for visual mode in fish.
This patch adds the readline commands `togglecase-letter` and
`togglecase-selection` to match the behavior of vim more closely. The
only difference is that in visual mode, the cursor is not modified.
Modifying the cursor in visual mode would require either moving it in
`togglecase-selection`, which seems outside its scope or adding
something like a `move-to-selection-start` readline command.
The description for an alias which already has escape sequences will
use backslash escapes for quoting; usually `string escape` can simply
quote it. Use a regex that accepts either escaping style.
Fixes#6798
This re-adds some false positives: functions, builtins and abbreviations
are suggested after commands like sudo but I don't think anyone had
complained about that.
Many people have mentioned wanting support for changing / yanking /
deleting between "" and '', meaning the commands `ci' ci" yi' yi" di' di"`,
so this adds that support in a generic, and thus potentially confusing way.
The concept is that we check for the character backwards and forwards
before making the selection. Unfortunately, this will also work for *any*
character that isn't `w` or `W`, so `cia` could change everything between
two `a` characters.
Looking through the [bind documentation](https://fishshell.com/docs/current/cmds/bind.html)
and input handler at `src/input.cpp`,
this is the best possible solution I could come up with until
`forward-jump` and `backward-jump` can accept input in the call to `bind`,
and not just from stdin, meaning we can write a binding as:
```
bind di\" backward-jump-till \" and repeat-jump-reverse ...`
```
If that were done, then other commands such as `di)` to go between `()` would
be possible.
There are also some added `y` bindings not part of #6648.
Let me know if you need anything else.

Naturally this does not work for many other editors/aliases,
but it's still nice that we can make it work for some common
editors without requiring any configuration.
Of course this approach is not terribly flexible; but it's
alwyas possible to just wrap edit_command_buffer and set an
EDITOR that knows about the cursor position. It doesn't
feel important enough to add a configuration option.

Mimic the behavior of Linux's `apropos -e` and ~BSD's `apropos -f` with

after the first match), it's also more correct.

Add the input function undo which is bound to `\c_` (control + / on
some terminals). Redoing the most recent chain of undos is supported,
redo is bound to `\e/` for now.
Closes#1367.
This approach should not have the issues discussed in #5897.
Every single modification to the commandline can be undone individually,
except for adjacent single-character inserts, which are coalesced,
so they can be reverted with a single undo. Coalescing is not done for
space characters, so each word can be undone separately.
When moving between history search entries, only the current history
search entry is reachable via the undo history. This allows to go back
to the original search string with a single undo, or by pressing the
escape key.
Similarly, when moving between pager entries, only the most recent
selection in the pager can be undone.
Same issue occurs here, as in #6270 (and fixed in 611a658 for `__fish_describe_command.fish`). Same reason. I've just copied the same workaround and changed the function name to match.
6902459566 was an attempt to not print
$status twice in the prompt. As a result we print $pipestatus but
not $status, which /usually/ is the same as $pipestatus[-1] --- unless
the builtin "not" is used, which inverts the $status of a job (it does
not alter $pipestatus).
As a result, the default prompt prints unexpected status codes:
~ > not false
~ [1]> not true
~ > not true | true
~ > not false | false
~ [1|1]>
This commit reintroduces printing of $status after $pipestatus, but only
if it is different from $pipestatus[-1].
Additionally, we only print anything at all if the $status is nonzero,
to avoid confusing output on `not false | false`
~ > not false
~ > not true
~ [0] 1> not true | true
~ [0|0] 1> not false | false
~ >
I think this is closer to users' expectations for those cases; they should
not have to think about this implementation detail of the not-statement.
At the moment the "prepend sudo" functionality always sets the cursor to
the end of the line. This changes it to restore the relative position of
the cursor.
It's now good enough to do so.
We don't allow grid-alignment:
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
becomes
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
It's just more trouble than it is worth.
The one part I'd change:
We align and/or'd parts of an if-condition with the in-block code:
```fish
if true
and false
dosomething
end
```
becomes
```fish
if true
and false
dosomething
end
```
but it's not used terribly much and if we ever fix it we can just
reindent.
We just do a cheesy version check and hope it works out.
If this is fixed in 10.15.4, we have to reenable it. If it still isn't
fixed in 10.16, we need to adjust it.

This prefixes files beginning with `-` with a `./` when generating

This was mostly dead, since $fish_color_host is set to normal in

(command pwd) uses the system's implementation of pwd. At least the GNU

So we're now more likely to be *correct*, and the alias benchmark is
about 20% *faster*.

Presently the completion engine ignores builtins that are part of the
fish syntax. This can be a problem when completing a string that was
based on the output of `commandline -p`. This changes completions to

after strings that do not tokenize.
Additionally, comments are stripped off the output of `commandline -p`.

Every builtin or function shipped with fish supports flag -h or --help to
print a slightly condensed version of its manpage.
Some of those help messages are longer than a typical screen;
this commit pipes the help to a pager to make it easier to read.
As in other places in fish we assume that either $PAGER or "less" is a
valid pager and use that.
In three places (error messages for bg, break and continue) the help is
printed to stderr instead of stdout. To make sure the error message is
visible in the pager, we pass it to builtin_print_help, every call of which
needs to be updated.

BSD `seq` produces a down-counting sequence when the second argument is
smaller than the first, e.g.:
$ seq 2 1

While GNU `seq` produces no output at all:

To accommodate for this behavior, only run `seq` when we are sure that
the second argument is greater than or equal to the first (in this case,
the second argument `line_count` should be greater than 1).

* Fix default Alt+W keybinding
The old keybinding would chop off the last line of the `whatis` output
when using a multi-line prompt. This fix corrects that.
* Make variable local and remove unneeded if statement
* Test that token is non-empty
Reproducer: type `: \<RET><M-p>`. This used to print an error due to builtin test receiving
too many arguments.
It looks like (commandline -j) can return multiple items, because a job can be broken up in multiple
lines terminated by backslashes.
With the new support for self-insert inserting a bound sequence,
the default binding for space as expanding abbreviations can be simplified
to just `self-insert expand-abbr`. This also fixes the bug where space
would cancel pager search.
By not manipulating each line or even each file at a time, we can go
back to `string` and piece together a pipeline that will execute
significantly faster than shelling out to `awk` will. This also removes
one of the few dependencies on `awk` in the codebase.
With this change, `__fish_print_hostnames` now finishes ~80% faster than
it used to a few commits back.
Reordering the `getent hosts` and read from `/etc/hosts` combined with
minimizing shelling and job invocations for parsing the output results
in a profiled and benchmarked ~42% decrease in the time it takes to run,
and that's on a machine with a very small hosts list in the first place.
This update also fixes the hadling of IPv6 addresses in the hosts
output, which were previously ignored, and ignores 127.* loopback
addresses in addition to the 0.0.0.0 address (plus adds support for
shorter IPv4 notations).

This previously effectively checked `string split ' '`s return status,
which was false if it didn't split anything. And while that should be
true if getent fails (because it should produce no output), it's also
true if it doesn't print a line with multiple aliases. Which should be
fairly typical.
Instead we use our new-found $pipestatus to check what getent returns,
in the assumption that it'll fail if it doesn't support hosts.

`getent hosts` is expensive-ish - ~50ms, so we don't want to run it

If you changed $__fish_git_prompt_show_informative_status, it

`eval` has always been implemented as a function, which was always a bit
of a hack that caused some issues such as triggering the creation of a
new scope. This turns `eval` into a decorator.

described in #4442, which should now no longer be the case.

If we switch the bind mode, we add a "force-repaint" there just to

mode-prompt and uses the cached values for the others.

This searched for package.json in any parent, so just like finding

This called `eval $fish_browser --version` to figure out if it is

That's really not worth it just to support edge-cases using a rather
unusual browser, to work around a bug in it.
Instead we just see if the browser name starts with "lynx", which
should work in 99.9% of cases.
This created another local version of the variable just for the if-block.
Can't say I love the space prefix, but then I think we have too many
of these modes anyway.
If you use these to figure out if there _are_ staged files, or dirty
or whatever, you currently need to check the output, which relies on
the configured character.
Instead, we let them also return a useful status.
Notably, this is *not* simply the status of the git call.
__fish_git_prompt_X returns 0 if the repo is X.
This works for untracked, but the "diff" things return 1 if there is a
diff, so we invert the status for them.

We were checking for the $TMUX variable to determine if we were
running under tmux. However when running the tests, the terminal becomes
expect, even though the TMUX variable is still set, so we spew tmux-isms
at expect. Check the value of $TERM for 'screen'.
This allows disabling _just_ the informative status.
We still also use the dirty and untracked variables, but only if
informative status hasn't explicitly been enabled.
If either of the two git config variables:
- bash.showDirtyState
- bash.showUntrackedFiles
is explicitly set to false, we will disable informative status, and
fall back on the non-informative version (most likely still with
either dirty or untracked files, since we already use the variables
for that).
These vars are read by the official git prompt, so we use them instead
of inventing our own "fish.showInformativeStatus".
(Note: This also uses $__fish_git_prompt_showdirtystate and friends,
but only when there's nothing set in the repo, and there's really no
reason to set those to false if using the informative status)

Expands the utility of `type -p foo` by allowing it to print the path to
the script that defines `foo` when `foo` is a valid function that was
sourced from a path on disk (rather than interactively defined).
This does not change the behavior of `type -P`/`type --force-path`,
which should have already been used if the desire was to resolve the
path to an executable file (otherwise the output would have been blank
if a function was shadowing an executable file of the same namea), so no
backwards compatibility issues are expected.
Previously, using special regex characters or slashes would result in an
error message, when pressing tab in a command-line such as
"man /usr/bin/time ".

I had previously introduced a lot of updates and fixes to npm registry

Don't bother setting a local $TERM_PROGRAM if it's unset: quoting
is enough to keep test happy. For the version numbers, 0"$var" is safe
against unset variables for numerical comparisons.

fish_indent is extremely resource-intensive on large inputs and can crash; it also does not handle

Work on #5402.
man.fish can be clarified a bit, by removing a superfluous early return. Additionally, performance can be
(ever so slightly) improved, by using the empty string to suffix an extra colon when `$MANPATH` is empty, as
described in `manpath(1)`. As `man` will internally call `manpath` as it starts, this eliminates a redundancy.
- No longer uses sed, sort, uniq, uname
- Stop doing too-clever filtering (e.g. the kernel thread stuff never

- Don't truncate for all OSen, instead just use the (correctly
- truncated) comm field.
