The documentation states that running `fish_config theme save` after
`fish_config theme choose [theme_name]` will result in "saving" the
currently chosen theme, but this does not match the actual behavior of
`fish_config theme save` which expects a trailing argument specifying
the name of the theme to select/persist.
Given that the documented way has been included in a release and that it
makes more sense than calling `fish_config theme save xxx` when you are
*loading from* xxx and not *saving to* xxx, this patch revises
`fish_config.fish` to support the documented behavior.
When `fish_config theme save xxx` is used, xxx is loaded w/ its specified colors
saved to the according variables in the universal scope. But if `fish_config
theme save` is used without a theme's name specified, then the currently
specified (known) fish color variables are persisted from whatever scope they're
currently in (usually in the global scope from previewing a theme) to universal
variables of the same name.
This does *not* catch color variables unknown to fish! If a theme and a
prompt agree on some variable to hold some color but it's not a color variable
known to fish, it won't be persisted!
Closes#9088.
This makes these tools usable in a pipe.
You can run
```fish
some-long-command | fish_clipboard_copy
```
to copy some command's output to your clipboard, and
```fish
fish_clipboard_paste | some-other-command
```
To feed your clipboard to some command.
When there are multiple screens worth of output and `history` is writing to the
pager, pressing Ctrl-C at the end of a screen doesn't exit the pager (`q` is
needed for that) but previously caused fish to emit an error ("write:
Interrupted system call) until we starting silently handling SIGINT in
`fd_output_stream_t::append()`.
This patch makes `history` detect when the `append()` call returns with an error
and causes it to end early rather than repeatedly trying (and failing) to write
to the output stream.
If EINTR caused by SIGINT is encountered while writing to the
`fd_output_stream_t` output fd, mark the output stream as errored and return
false to the caller but do not visibly complain.
Addressing the outstanding TODO notwithstanding, this is needed to avoid
littering the tty with spurious errors when the user hits Ctrl-C to abort a
long-running builtin's output (w/ the primary example being `history`).
The previous check was including these as relative includes, meaning the actual
system header files weren't actually being explicitly included and the check
could spuriously fail.
CMAKE_EXTRA_INCLUDE_FILES doesn't seem to have a way to specify that the
includes should be treated as system/global includes and CHECK_TYPE_SIZE() isn't
documented as being affected by any other variables that do, so switch to
another method altogether.
This requires that `struct winsize` have a member `ws_row`, but as best as I can
tell that is always the case.
Closes#9279.
In the presence of modified files, assume `git checkout ...` is being
invoked/completed with the intention of restoring modifications. Even if not the
case, this list is likely going to be shortest if someone is about to change
branches.
Afterwards, list branches (with local branches sorted by recency), then remote
unique remotes, heads, tags, and recent commits. The order of these last four
is up for debate, and honestly if any of them generate a lot of results it makes
finding what you're actually looking for in the autocompletions a lot harder.
It may be better to merge these last contenders and sort them by individual
recency instead, but that does make the pager entries rather messy (and we would
need to add a new function to do that in order to interleave them in the desired
sort order but preserve the overall sort after the completions subshell
terminates).
It's really hard to see where -k is applied to git completions, so always group
it with -a to make it more consistent and easier to spot.
There should be no functional changes in this commit.
* 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
`describe-future-incompatibilities` is no longer a supported subcommand. It was
also never something very popular so we don't have to worry about older
versions.
[ci skip]
We only erase existing globals for some of the theme-related variables
but not for all the `known_colors`, causing `fish_config` to still emit
warnings for these if saving a theme choice after trying it.
Up to now, in normal locales \x was essentially the same as \X, except
that it errored if given a value > 0x7f.
That's kind of annoying and useless.
A subtle change is that `\xHH` now represents the character (if any)
encoded by the byte value "HH", so even for values <= 0x7f if that's
not the same as the ASCII value we would diverge.
I do not believe anyone has ever run fish on a system where that
distinction matters. It isn't a thing for UTF-8, it isn't a thing for
ASCII, it isn't a thing for UTF-16, it isn't a thing for any extended
ASCII scheme - ISO8859-X, it isn't a thing for SHIFT-JIS.
I am reasonably certain we are making that same assumption in other
places.

Handle differently declared posix_spawnxxx_t on macOS
On macOS, posix_spawnattr_t and posix_spawn_file_actions_t are declared as void
pointers, so we can't use maybe_t's bool operator to test if it has a value.

Update maybe_t tests to reflect dynamic bool conversion
maybe_t<T> is now bool-convertible only if T _isn't_ already bool-convertible.

Make maybe_t a little harder to misuse
We've had a few bugs over the years stemming from accidental misuse of maybe_t
with bool-convertible types. This patch disables maybe_t's bool operator if the
type T is already bool convertible, forcing the (barely worth mentioning) need
to use maybe_t::has_value() instead.
This patch both removes maybe_t's bool conversion for bool-convertible types and
updates the existing codebase to use the explicit `has_value()` method in place
of existing implicit bool conversions.
The parent commit made the destructor of the DIR* member close it if necessary
(i.e. only if it's not null). This means that we can use the same logic in
the move constructor (where the source DIR* is null) and for move assignment
(where it might not be).
No functional change.
dir_iter_t closes its DIR* member in two places: the move assignment and
the destructor. Simplify this by closing it in the destructor of the DIR*
member which is called in both places. Use std::unique_ptr, which is shorter
than a dedicated wrapper class. Conveniently, it calls the deleter only if
the pointer is not-null. Unfortunately, std::unique_ptr requires explicit
conversion to DIR* when interacting with C APIs but it's probably still
better than a wrapper class.
This means that the noncopyable_t annotation is now implied due to the
unique_ptr member.
Additionally, we could probably remove the user-declared move constructor
and move assignment (the compiler-generated ones should be good enough). To
be safe, keep them around since they also erase the fd (though I hope we
don't rely on that behavior anywhere).
We should perhaps remove the user-declared destructor entirely but
dir_iter_t::entry_t also has one, I'm not sure why. Maybe there's a good
reason, like code size.
No functional change.
