This half-reverts commit a3cb1e2dcd,
avoiding the bit that passed arguments differently.
Note that this means the initial bug is kept in the hardcoded fallback title.
Fixes#7749.
* Ensure web_config works on WSL
web_config could sometimes fail on WSL if the user chose not to append
windows directories to their linux $PATH. This change ensures that the
cmd.exe executable is found in most cases even if windows directories
are not appended to $PATH on linux.
An error message letting the user know that cmd.exe was not found, and
that they should add the cmd.exe dir to their $PATH before running
fish_config is displayed if cmd.exe is still not found.
* Exit with a non 0 status code if cmd.exe is not found
My bet is that the Illumos, Cygwin, and WSL are not the only Unix-like
systems where the SIGIO notifier won't work, and since we have a good
enough and portable alternative that we can use be default on other
platforms where we don't specifically know it'll work, it doesn't make
sense not to go with that one instead.
Even if this patch is reverted at some point and we go back to
blacklisting platforms that *don't* support the SIGIO strategy, this is
almost certainly the right choice for inclusion in a minor release like
3.2.0.
See discussion in #6585.
In this context, as it stands, $last_pid will give fish's pid (because
of pgroup shenanigans).
Since that doesn't really work, just `disown` without and let fish
figure out what the last process was.
Theoretically this has an issue if someone started a background
process *before* the python script *and* that exits before we run
disown.
That's a vanishingly small window and this is only run on first start,
so it seems acceptable.
Fixes#7739.
NetBSD's sleep quits when foregrounded sometimes. I'm not entirely
sure *why*, but this is reproducible with the default /bin/sh, so it's
not our fault.
Because this fails our tests, go back to using cat *there*, because we
can't use it on macOS - 4c9d01cab0.
Apparently the fix for #6269 doesn't work until we set job-control to
full, which we won't do for this release.
So just drop it from the CHANGELOG.
See #7739.
* memset/memzero needs cstring/string.h (again)
* winsize_t requires an impl from <sys/termios.h>
With this patch, I was able to get fish master to build on Solaris 11.4
without any additional dependencies (after installing gcc 7, git, and
cmake). I think the ncurses dependency can be dropped from the
OpenIndiana package?
The GitHub documentation states that python3 w/ pip3 is already
installed, and homebrew is slow as molasses (and when it finally runs it
gives a warning about python already being installed and up to date).
Since smartcase, we could land in a situation where we offer one
option in the pager, which is awkward.
So detect this and just insert the option directly, we can add any
more smartness later.
Fixes#7738.
Without true handling of UTF-16 surrogate pairs, all we can do is
properly detect the BMP range in UTF-16 environments and bail if the
input is in a non-BMP region.
There isn't much else we can do as it is incorrect to encode the
surrogate pairs themselves (fish doesn't know what to do with them and
they're illegal under either of UTF-8 or UTF-32).
(I'm not aware of fish being used in any UTF-16 platforms other than
Cygwin.)
Previously, the interop glue for more friendly access to PCRE2's
fixed-size values was only used when char32_t/wchar_t were
interchangeable and PCRE2 was used with a global 32-bit unit width set;
this patch extends the same to char16_t when wchar_t is also 16-bits
(namely on Cygwin) to avoid compilation fpermissive warnings about casts
between types of potentially different sizes.
Reported in #6585.
The only thing we know ever triggered this is old macOS versions,
there's no need to use it for everyone else.
Since this uses try_run it breaks when cross-compiling, which
shouldn't be a common thing on macOS.
Fixes#7737
Those platforms should not be using the sigio notifier in the first
place, this just stops them from failing to be able to compile fish
altogether.
See #6585
The user may write for example:
echo foo >&5
and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.
Note that the reverse is "allowed" but ignored:
echo foo 5>&1
this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.
The screen output code predates the ENCODE_DIRECT scheme, and
directly-encoded bytes were not being properly output. This manifested as
private-user characters being mangled when printed as part of fish_prompt.
Just use str2wcstring instead.
Fixes#7723
wcs2string_appending is like wcs2string, but appends to a std::string
instead of creating a new one. This will be more efficient when a string
can be reused, or if we want to accumulate multiple wcstrings into a
single std::string.
They are of variable length, taking semicolon-separated ASCII characters
and not single chars/bytes as the parameters. Additionally, the global
maximum size for a CSI is 16 characters (NPAR), even though I believe
the maximum possible mouse-tracking CSI is 12 characters.
fish maintains two tty modes: one for itself and one for external
commands. The external command mode is also used when executing
fish-script key bindings, which was added in 5f16a299a7 (note that
commit had the wrong issue, the correct issue is #2114).
Prior to this fix, when switching to external modes, we would also reset
the tty's foreground color. This bumped tty's timestamp, causing us to
believe that the tty had been modified, and then repainting the prompt. If
the prompt were multi-line, we would repaint the whole prompt starting
from its second line, leaving a trailing line above it.
It would be reasonable to save the tty timestamp after resetting the
color, but given that using external modes for keybindings is new, it's
better to instead not reset the color in this case. So migrate the color
resetting to only when we run external commands.
Fixes#7722
The default case for string literals like `"foo"` is a single trailing
nul, and that's what we have almost everywhere. By checking the
second-to-last index for a non-nul byte, we can skip the recursive
invocation, thus speeding up compilation that teeny, tinsy bit faster.
Rather than making the run-time complexity of the algorithm 𝒪(n) where n
is the length of the string, make it 𝒪(k) where k is the number of
trailing nul bytes.
The second parameter `index` with a default non-value is in lieu of a
helper function that would have had a name like `count_trailing_nuls()`.
e94f86e6d2 removed it in favor of using
fish_wcstod, but this broke the *output* - math currently prints
numbers with "," and then can't read them.
So we partially revert it until we come up with something better.
Maybe set $LC_NUMERIC globally inside fish?
fish_indent used to increment the indentation level whenever we saw an escaped
newline. This broke because of recent changes to parse_util_compute_indents().
Since parse_util_compute_indents() function already indents continuations
there is not much to do for fish_indent - we can simply query the indentation
level of the newline. Reshuffle the code since we need to pass the offset
of the newline. Maybe this can even be simplified further.
Fixes#7720
Bind \cc like normal, since we now no longer use a function, and bind
some important control bindings like \cs and the ever-important emacs \cb/f/p/n.
What really kills the usability here is the up-line vs up-or-search.
This still showed the background gradient, which is just a waste and
looks weird.
Instead make the actual content fullscreen (except for the border
radius, for now)
