When running inside SSH, Control-X runs a clipboard utility on the remote
system. For pbcopy (and probably clip.exe too) this means that we write to the
remote system's clipboard. This is usually not what the user wants (although
it is consistent with fish_clipboard_paste). When X11 forwarding is used,
xclip/xsel copy to the SSH client's clipboard, which is what most users want.
When we don't have X11 forwarding, we need a different solution. Fortunately,
modern terminal emulators implement the OSC 52 escape sequence for setting
the clipboard of the terminal's system. Use it in fish_clipboard_copy.
Tested in SSH and Docker containers on foot, iTerm2, kitty, tmux and xterm
(this one requires "XTerm.vt100.allowWindowOps: true").
Should also work in GNU screen and Windows Terminal. On terminals that don't
support OSC 52 (like Gnome Terminal or Konsole), it seems to do nothing.
Since there does not seem to be a way to feature-probe OSC 52, let's just
always do both (pbcopy and friends as well as OSC 52). In future, we should
probably stop calling pbpaste and clip.exe, at least on remote systems.
I think there is also an escape sequence to request pasting the system
clipboard but that's less important and less popular, possibly due to
security concerns.
* Add clojure completions
* More ideomatic fish code
* Clojure completions in separate file
* Aboid use of psb using bb -e
* Return early when bb can not be found
* Remove superflous escape
* Another superflous escape
This adds preprocessor defines for _LARGEFILE_SOURCE and
_FILE_OFFSET_BITS=64 and a few others, fixing a bug that was reported on
gitter. This prevents issues when running fish on 32 bit systems that
have filesystems with 64 bit inodes.
* Replace ";" with "\n" in alias-generated functions
This can let us add a "#" in our aliases to make
them ignore additional arguments.
* Update changelog about aliases that ignore arguments
* Update test for alias.fish
This is now compliant with the aliases that can
ignore arguments.
When fish runs with job control enabled, it transfers ownership of the
tty to a child process, and then reclaims the tty after the process
exits. If job control is disabled then fish does not transfer or reclaim
the tty.
It may happen that the child process creates a pgroup and then transfers
the tty to it. In that case fish will not attempt to reclaim the tty, as
fish did not transfer it. Then when fish reads from stdin it will
receive SIGTTIN instead of data.
Fix this by unconditionally claiming the tty in readline().

* added completions for sad and added note in changelog
* ran fish_indent on completion file

This reimplements ridiculousfish/control_r which is a more future-proof
approach than #6686.
Pressing Control+R shows history in our pager and allows to search filter
commands with the pager search field.
On the surface, this works just like in other shells; though there are
some differences.
- Our pager shows multiple results at a time.
- Other shells allow to use up arrow/down arrow to select adjacent entries
in history. Shouldn't be hard to implement but the hidden state might
confuse users and it doesn't play well with up-or-search, so this is
left out.
Users might expect the history pager to use subsequence matching (fuzzy
matching) like the completion pager, however due to the history pager design it
uses substring matching. We could change this in future, however that means
we would also want to change the ordering from "reverse-chronological" to
"longest common subsequence" (e.g. what fuzzy finders do), because otherwise
a query "fis" might give this ordering:
fsck /dev/disk/by-partlabel/Linux\x20filesystem
fish
which is probably not what the user wants.
The pager shows only a small number of history items at a time. This is
because, as explained above, the history pager does not support subsequence
matching, so navigating it does not scale well.

That's apparently errno 86 on macOS, and it's triggered when the
architecture is wrong.
I'll leave other macOS errors to the macOS users.
See #9052.
(cherry picked from commit 60f87ef3be)
This was supposed to be number of lines in the prompt minus 1, but
string repeat added one.
Also it triggered even in case of the stopped job message, which is
already repainted differently.
So we add it when we need to repaint ourselves.
As a bonus add a newline before in that case so the message isn't
awkwardly printed into the commandline.
Fixes#9044.

Previously, the search text is used to find out which part of the
updated command line should be highlighted during a history search. This
approach will cause the incorrect part to be highlighted when the line
contains multiple instances of the search text.
To address this, we have to find out exactly where to highlight, i.e.
the offset of the current token in the command line (0 if not a token
search) plus the offset of the search text in the match.
If you run an initial command via `fish -c`, and that command is
cancelled e.g. via control-C, then ensure that the cancellation signal
is cleared before running config files.
Fixes#9024

Discussions with the tmux maintainer show that:
1. We no longer need the passthrough sequence at all (and it's
deactivated by default)
2. Tmux can check if the outer terminal supports cursor shaping

Commit ad9b4290e optimized git completions by adding a completion that would
run on every completion request, which allows to precompute data used by
other completion entries. Unfortunately, the completion entry is not run
when the commandline contains a flag like `git -C`. If we didn't
already load git.fish, we'd error. Additionally, we got false positive
completions for `git diff -c`.
So this hack was a very bad idea. We should optimize in another way.

The recent improvements to multiline prompts and vi-mode in #3481 appear
to be sufficient to make iTerm2 well behaved, so remove our hack which
disabled it by default.
Fixes#3696
The fix for #3481 caused us to save the screen status after external
commands were run, fixing an unnecessary abandon-line when switching
modes. But we may also run commands not directly as part of a binding,
but instead via an on-variable event, e.g. for fish_bind_mode.
Extend this fix to all bindings, guarded by changes to exec_count. Now
any time an external command runs as part of a binding we should pick up
changes to the tty and not abandon the line.
Fixes#3481 again.
This concerns running a key binding which invokes a command. If that
command modifies the tty, then fish will spot the modification later and
then react to it by redrawing the prompt. However tty modifications may
be benign or desirable; for example switching the cursor from a line to
a block. Fix this by re-fstating the tty after running external
commands.
Fixes#3481
Previously, `kill-whole-line` kills the line and its following
newline. This is insufficient when we are on the last line, because
it would not actually clear the line. The cursor would stay on the
line, which is not the correct behavior for bindings like `dd`.
Also, `cc` in vi-mode used `kill-whole-line`, which is not correct
because it should not remove any newlines. We have to introduce
another special input function (`kill-inner-line`) to fix this.
This teaches `--on-signal SIGINT` (and by extension `trap cmd SIGINT`)
to work properly in scripts, not just interactively. Note any such
function will suppress the default behavior of exiting. Do this for
SIGTERM as well.

Pressing Ctrl-D while a command is running results in a null key code in
our input queue. That key code is bound to insert a space (without expanding
abbreviations). Make it only insert a space if the commandline is non-empty,
to accommodate this use case.
This probably affects other keys as well.

c4fb857dac (in 3.4.1) introduced a regression where process_exit
events would only fire once the job itself is complete. Allow
process_exit events to fire before that. Fixes#8914.
We don't need to make the feature flag descriptions as terse as
possible, I believe some people were confused by what this all means,
so we can dedicate a few lines to explaining it again.

Prior to this change, if you tab-completed a token with a wildcard (glob), we
would invoke ordinary completions. Instead, expand the wildcard, replacing
the wildcard with the result of expansions. If the wildcard fails to expand,
flash the command line to signal an error and do not modify it.
Example:
> touch file(seq 4)
> echo file*<tab>
becomes:
> echo file1 file2 file3 file4
whereas before the tab would have just added a space.
Some things to note:
1. If the expansion would produce more than 256 items, we flash the command
line and do nothing, since it would make the commandline overfull.
2. The wildcard token can be brought back through Undo (ctrl-Z).
3. This only kicks in if the wildcard is in the "path component
containing the cursor." If the wildcard is in a previous component,
we continue using completions as normal.
Fixes#954.
When expanding command substitutions, we use a naïve way of detecting whether
the cmdsub has the optional leading dollar. We check if the last character was
a dollar, which breaks if it's an escaped dollar. We wrongly expand
\$(echo "") to the empty string. Fix this by checking if the dollar was escaped.
The parse_util_* functions have a bunch of output parameters. We should
return a parameter bag instead (I think I tried once and failed).
Given
set var a
echo "$var$(echo b)"
the double-quoted string is expanded right-to-left, so we construct an
intermediate "$varb". Since the variable "varb" is undefined, this wrongly
expands to the empty string (should be "ab"). Fix this by isolating the
expanded command substitution internally. We do the same when handling
unquoted command substitutions.
Fixes#8849
The tmp and prompt variables collide with variables used as arguments.
Just avoid them entirely, at the cost of making the internals of the
functions somewhat more complicated.
Closes#8836.
