Since we enable/disable terminal protocols whenever we pass terminal ownership,
tests can no longer run in parallel on the same terminal.
For the same reason, readline shortcuts in the gdb REPL will not work anymore.
As a remedy, use gdbserver, or lobby for CSI u support in libreadline.
Add sleep to some tests, otherwise they fall (both in CI and locally).
There are two weird failures on FreeBSD remaining, disable them for now

Design and implementation borrows heavily from Kakoune.
In future, we should try to implement more of the kitty progressive
enhancements.
Closes#10359
To do so add an ad-hoc "commandline --search-field" to operate on pager
search field.
This is primarily motivated because a following commit reuses the
fish_clipboard_paste logic for bracketed paste. This avoids a regression.
A long standing issue is that bindings cannot mix special input functions
and shell commands. For example,
bind x end-of-line "commandline -i x"
silently does nothing. Instead we have to do lift everything to shell commands
bind x "commandline -f end-of-line; commandline -i x"
for no good reason.
Additionally, there is a weird ordering difference between special input
functions and shell commands. Special input functions are pushed into the
the queue whereas shell commands are executed immediately.
This weird ordering means that the above "bind x" still doesn't work as
expected, because "commandline -i" is processed before "end-of-line".
Finally, this is all implemented via weird hack to allow recursive use of
a mutable reference to the reader state.
Fix all of this by processing shell commands the same as both special input
functions and regular chars. Hopefully this doesn't break anything.

Call fish_should_add_to_history to see if a command should be saved
If it returns 0, it will be saved, if it returns anything else, it
will be ephemeral.
It gets the right-trimmed text as the argument.
If it doesn't exist, we do the historical behavior of checking for a
leading space.
That means you can now turn that off by defining a
`fish_should_add_to_history` that just doesn't check it.

Issue #10194 reports Cobra completions do
set -l args (commandline -opc)
eval $args[1] __complete $args[2..] (commandline -ct | string escape)
The intent behind "eval" is to expand variables and tildes in "$args".
Fair enough. Several of our own completions do the same, see the next commit.
The problem with "commandline -o" + "eval" is that the former already
removes quotes that are relevant for "eval". This becomes a problem if $args
contains quoted () or {}, for example this command will wrongly execute a
command substituion:
git --work-tree='(launch-missiles)' <TAB>
It is possible to escape the string the tokens before running eval, but
then there will be no expansion of variables etc. The problem is that
"commandline -o" only unescapes tokens so they end up in a weird state
somewhere in-between what the user typed and the expanded version.
Remove the need for "eval" by introducing "commandline -x" which expands
things like variables and braces. This enables custom completion scripts to
be aware of shell variables without eval, see the added test for completions
to "make -C $var/some/dir ".
This means that essentially all third party scripts should migrate from
"commandline -o" to "commandline -x". For example
set -l tokens
if commandline -x >/dev/null 2>&1
set tokens (commandline -xpc)
else
set tokens (commandline -opc)
end
Since this is mainly used for completions, the expansion skips command
substitutions. They are passed through as-is (instead of cancelling or
expanding to nothing) to make custom completion scripts work reasonably well
in the common case. Of course there are cases where we would want to expand
command substitutions here, so I'm not sure.
This prefers `-s` to `-v` - we have a *lot* more uses of `command -s`, it's the easier
mnemonic *and* the more compatible-with-fish option.
Also we don't really need the separate section that explains what
these options do *again*.
This can be bound like `bind \cl clear-screen`, and is, by default
In contrast to the current way it doesn't need the external `clear`
command that was always awkward.
Also it will clear the screen and first draw the old prompt to remove
flicker.
Then it will immediately trigger a repaint, so the prompt will be overwritten.
This was the remaining immediately actionable part of #7375.
It's not definitely the last word, but a change here would require a
bigger plan.
Fixes#7375
This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.
During development, for a while `path change-extension` would return 0
when it found an extension to change.
This was later changed to returning 0 if there are any path arguments.
Neither of which is *super* useful, I admit, but we've picked one and
the docs shouldn't contradict it.
This was accidentally changed in 3.2.0, when type was made a builtin.
Since it's been 4 releases and nobody has noticed, rather than
breaking things again let's leave it as it is, especially because the
option is named "--no-functions", not "--no-functions-or-builtins".
After accidentally running a command that includes a pasted password, I want
to delete command from history. Today we need to recall or type (part of)
that command and type "history delete". Let's maybe add a shortcut to do
this from the history pager.
The current shortcut is Shift+Delete. I don't think that's very discoverable,
maybe we should use Delete instead (but only if the cursor is at the end of
the commandline, otherwise delete a char).
Closes#9454
