This function is supposed to return "the next directory". Because this
is imperfect, it only tries to.
Except it went to all the trouble of figuring out the type and then
just... returned it anyway.
This has nice speedups in globs with directory components like `*/` or
`**`. I have observed 1.1x to 2.0x.
We could also return when we know it's definitely a directory and then
skip a stat() later, but preliminary testing seemed to show that's not
worth much.
GIT_SHALLOW 1 here improves generation speed and _deps in the build
dir like is 6 or 7 MB less according to `du`.
Bump the minimum PCRE2 to 10.35 on account of we use
PCRE2_SUBSTITUTE_LITERAL.
These are now available on all supported platforms, and the download
process tends to break on build workers (where Internet access is
deliberately denied).
Take advantage of additional cleanup unlocked by this refactoring,
including eliminating unneeded error returns and simplifying some
control flow.
No user-visible behavior change expected here.
This switches builtin_string from using PCRE2 directly, to using the new re
component. This simplifies some code and removes redundancy.
No user-visible behavior change expected here.
This migrates our PCRE2 dependency from builtin/string.cpp to new files
re.h/re.cpp, allowing regexes to be used in other places in fish.
No user-visible behavior change expected here.
- Generally better descriptions,
- uname checks to not complerte unavailable options on
NetBSD, FreeBSD, DragonFly, Solaris, Darwin
- Describe/complete GNU's --time=access,mtime... arg
- Remove -f it is a no-op and not documented.
When we want to print something while the prompt is still active, we move the
cursor by printing a newline for each line in the prompt beyond the first
one. As established by 80fe0a7fc (fish_job_summary: Format message better
for multiline prompts, 2022-06-28), our use of "string repeat" actually
prints an extra newline. Let's remove it here as well.
This switches the flag_to_function from a map to just an ordinary switch
statement. This saves some memory/startup time and removes some
relocations. No functional change here.
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.
(cherry picked from commit fee5a9125a)
This switches to using the CMake FetchContent path to dynamically download
and build PCRE2, allowing us to drop the vendored sources.
The FISH_USE_SYSTEM_PCRE2 CMake option is kept, but if false it now means
fetch-and-build PCRE2 rather than building vendored sources.
Note FetchContent was introduced in CMake 3.11. That is now a prerequisite
for building fish with FISH_USE_SYSTEM_PCRE2 disabled.
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.
This adds a line to `set --show`s output like
```
$PATH: originally inherited as |/home/alfa/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/var/lib/flatpak/exports/bin|
```
to help with debugging.
Note that this means keeping an additional copy of the original
environment around. At most this would be one ARG_MAX's worth, which
is about 2M.
This is sort of slow because it's called hundreds of times.
We used to have a cache, introduced in ad9b4290e, but it was removed
in fee5a9125a because it had
false-positives.
So what we do, because the issue is that this is called hundreds of
times per-commandline, we cache it keyed on the commandline.
This speeds up `complete -C'git sta'` by a factor of 2.3x.
It's still useful without, for instance to implement a command that
takes no options, or to check min-args or max-args.
(technically no optspecs, no min/max args and --ignore-unknown does
nothing, but that's a very specific error that we don't need to forbid)
Fixes#9006
