Today,
bind foo "commandline -f expand-abbr; commandline -i \n"
does not work because this
1. enqueues an expand-abbr readline event
2. "commandline -i" inserts \n
3. processes the expand-abbr readline event
Since there is no abbreviation on the new line, this doesn't do anything.
PR https://github.com/fish-shell/fish-shell/pull/9398 would fix this
particular instance however it does not fix the issue that "commandline -i"
is run before the expand-abbr is processed by the reader. This is harmless
here but there would be a problem if "commandline" tried to read commandline
state that was created by a preceding command.
It's not super clear to me whether the above binding should work as one
would naively expect. That would imply that "commandline" would need to
drain all input events (at least all synthetic ones) from the input queue,
to ensure it sees the current state.
Fortunately the parent commit makes it so if we separate them
bind foo "commandline -f expand-abbr" "commandline -i \n"
both will be separate events and the commandline state will be synced after
each of them. This fixes abbreviation expansion here.
Also, we can now mix readline cmds and shell commands, which makes it shorter.
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.

Most chat programs I found use Shift+Return to insert a newline while plain
Return sends the message. One user reported having only tried Shift+Return
and not knowing about Alt+Return.
No release notes yet because this only works on a very small number of
terminals. Once we enable CSI u, this should work on most modern terminals.
Multiline search strings are weirdly broken (inserting control characters
in the command line) and probably not very useful anyway.
On the other hand I often want to compose a multi-line command
from single-line commands I ran previously.
Let's support this case by limiting the initial search string to the current
line; and replace only that line.
Alternatively this could operate on jobs (that is, replace a surrounding
"foo | bar") instead of using line boundaries.
This is resistant to misuse by including O_DIRECTORY in the open flags and it is
a separate function from {w,}open_cloexec() in preparation for making that one
return a `File` instead of an `OwnedFd`.
`intersects()` is "any of" while `contains()` is "all of" and while it makes no
difference when testing a single bit, I believe `contains()` is less brittle
for future maintenance and updates as its meaning is clearer.
</pedantic>
More work in prep for having wopen_cloexec() return `File` directly.
This eliminates checking for an invalid fd and makes both ownership and
mutability clear (some more operations that involve changes to the underlying
state of the fd now require `&mut File` instead of just a `RawFd`).
Code that clearly does not use non-blocking IO is ported to use
`Write::write_all()` directly instead of our rusty port of the `write_loop()`
function (which handles EAGAIN/EWOULDBLOCK in addition to EINTR, while
`write_all()` only handles the latter).
Add git as a build requirement. Package name guessed then confirmed by searching
on rpm.pbone.net against openSUSE Tumbleweed.

The %{_docdir} macro is defined, but due to an oversight is not passed
to CMake in some versions of openSUSE where it should be.
Use doc directives to avoid mucking around with cp.
gpg's --use-embedded-filename is a dangerous option that can cause gpg
to write arbitrary content to arbitrary files.
According to the GnuPG maintainer, this is not an option recommended
for use (https://dev.gnupg.org/T4500). Fish shouldn't encourage users
to supply it.
I've offered https://dev.gnupg.org/T6972 to upstream to make it even
more clear that this option is a bad idea.
While removing it, we might as well also remove
--no-use-embedded-filename, since it is effectively a no-op.

Some of the completions recently introduced called Blender itself to query some
arguments, and Blender sometimes prints messages to stderr. This output was not
filtered, resulting in the shell printing irrelevant messages during completion.
(cherry picked from commit 4f3e7ddef0)
This is a step towards converting `wopen_cloexec()` to return `File` instead of
`OwnedFd`/`AutocloseFd`.¹
In addition to letting us use native standard library functions instead of
unsafe libc calls, we gain additional semantic safety because `File` operations
that manipulate the state of the fd (e.g. `File::seek()`) require a `&mut`
reference to the `File`, whereas using `RawFd` or `OwnedFd` everywhere leaves us
in a position where it's not clear whether or not other references to the same
fd will manipulate its underlying state.
¹ We actually wouldn't even need `wopen_cloexec()` at all (just a widechar
wrapper) as Rust's native `File::open()`/`File::create()` functionality uses
`FD_CLOEXEC` internally.
I used below script to list all GitHub issues and PRs that are not yet
mentioned in the changelog. It's almost empty now.
While at it, curate the "notable" section and move some entries around,
notably from "interactive improvements" to "bindings".
