This function only ever returns true if target_os=linux, so we need to invert
the OS check.
In the first invocation, this function may allocate heap memory.
Clarify that this is safe.
[ja: I don't have the original commit handy so I made up the log message]
The following "Port execution" commit will use RefCell for the wait handle
store. If we hold a borrow while we are running an event (which may run
script code) there will be a borrowing conflict. Avoid this by returning
the borrow earlier.
Given an env like
foo
bar=baz
we would set "foo" to empty due to a typo.
The typo is pointed out by a PORTING comment.
Luckily I don't think we ever hit this case because that would mean our
parent process has a serious bug. Rust's std::env::vars_os() skips env
lines that don't contain a "=" char. This seems like a reasonable behavior
for us too. Do that.
This makes it so expand_intermediate_segment knows about the case
where it's last, only followed by a "/".
When it is, it can do without the file_id for finding links (we don't
resolve the files we get here), which allows us to remove a stat()
call.
This speeds up the case of `...*/` by quite a bit.
If that last component was a directory with 1000 subdirectories we
could skip 1000 stat calls!
One slight weirdness: We refuse to add links to directories that we already visited, even if they are the last component and we don't actually follow them. That means we can't do the fast path here either, but we do know if something is a link (if we get d_type), so it still works in common cases.

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 uses "screen.reset_line" to move the cursor without informing the
reader's machinery (because that deals with positions *in the
commandline*), but then only repainted "if needed" - meaning if the
reader thought anything changed.
That could lead to a situation where the cursor stays at column 0
until you do something, e.g. in
```fish
bind -m insert u undo
```
when you press alt+u - because the *escape* calls repaint-mode, which
puts the cursor in column 0, and then the undo doesn't, which keeps it
there.
Of course this binding should also `repaint-mode`, because it changes
the mode.
Some changes might be ergonomic:
1. Make repaint-mode the default if the mode changed (we would need to
skip it for bracketed-paste)
2. Make triggering the repaint easier - do we need to set
force_exec_prompt_and_repaint to false here as well?
Anyway, this

This was introduced as a workaround to #7215 - xdg-open's generic path
wouldn't background graphical apps.
This has been fixed a month ago in xdg-open, so we can stop doing it.
The good news is this also allows terminal apps to be used again, so
it
Fixes#10045
(cherry picked from commit f8e38819a5)
This is a sensible thing to do, and fixes some cases where we're
state-dependent.
E.g. this fixes the case in the pager where some things are bold and
some aren't, because that bolding is (rather awkwardly) implicitly
triggered when we have a background, and so we don't notice we need to
re-do that bolding after we moved to the next line because we think we
still have the same color.
Fixes#9617
(cherry picked from commit 10d91b0249)
This was already supposed to handle `--foo=bar<TAB>` cases, except it
printed the `--foo=` again, causing fish to take that as part of the
token.
See #9538 for a similar thing with __fish_complete_directories.
Fixes#10011
(cherry picked from commit b03327f5d2)
I sometimes find myself doing something like this:
- Look for a commandline that includes "echo" (as an example)
- Type echo, press up a few times
- I can't immediately find what I'm looking for
- Press ctrl-r to open up the history pager
- It uses the current commandline as the search string,
so now I'm looking for "echo foobar"
This makes it so if the search string already is in use, that's what
the history-pager picks as the initial search string.

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.

(cherry picked from commit 0e81d25b36)
Without this, a recipe containing a trailing backslash followed by a line not
beginning with tab (like any non-continued recipe lines would) would result in
the continuation showing up in completions.
Whenever a line ends in a backslash, consider the next line invalid as a target.
Regex explanation:
^([^#]*[^#\\])? -- optional prefix not containing comment character and not
ending in backslash
(\\\\)*\\$ -- 2n+1 backslashes at end of line (handles escaped backslashes)

* Some temporary change until compose - commit
* First draft
* Fix an error that prints double completion
* Fix completion errors. Add rpm-ostree alias.
Fix cimpletion where it trigger by multiple commands.
Add update and remove, which are aliases for upgrade and uninstall.
* Remove -r when it is unnecessary
Some command need path completion for arguments no matter what,
which makes -r flag useless
* Remove -x for compose image
-x does not block the path anyway
* Add missing short otpion in compose image
Revert the last change to block -l completion
* Fix description
Fix multiple description.
(cherry picked from commit 9d0d16686e)
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.

This fixes the following deadlock. The C++ functions path_get_config and
path_get_data lazily determine paths and then cache those in a C++ static
variable. The path determination requires inspecting the environment stack.
If these functions are first called while the environment stack is locked
(in this case, when fetching the $history variable) we can get a deadlock.
The fix is to call them eagerly during env_init. This can be removed once
the corresponding C++ functions are removed.
This issue caused fish_config to fail to report colors and themes.
Add a test.
This was pretty annoying on rust release day, because it introduced
new warnings.
Specifically 1.73 introduced a spurious one about PartialOrd and Ord
disagreeing when both were in fact #derive-d.
Unlike our C++ tests, our Rust tests fail as soon as an assertion fails.
Whether this is desired is debatable; it seems fine for
most cases and is easier to implement.
This means that Rust tests usually don't need to print anything besides
what assert!/assert_eq! already provide.
One exception is the history merge test. Let's add a simple err!() macro to
support this. Unlike the C++ err() it does not yet print colors.
Currently all of our macros live in common.rs, to keep the import graph simple.
Notably this exposes config.h to Rust (for UVAR_FILE_SET_MTIME_HACK).
In future we should move the CMake checks into build.rs so we can potentially
get rid of CMake.
On the following "Port execution" commit, ASan will complain if we read
beyond a terminating null byte in get_autosuggestion_performer(). This is
actually working as intended but we need to appease ASan somehow..
get_pwd_slash() uses "if var.is_empty()" but it should be "if !var.is_empty()".
This wasn't a problem so far because in practice most code paths use the
get_pwd_slash() override from EnvStackImpl. The generic one is used in the
upcoming unit tests.
