This allows adjusting a pattern string so that it matches an entire
string, by wrapping the regex in a group like ^(?:...)$
This is a workaround for the fact that PCRE2_ENDANCHORED is unavailable
on PCRE2 prior to 2017, so we have to adjust the pattern instead.
Also introduce an overload of match() which creates its own
match_data_t.
We have had multiple crashes for relative CDPATH entries. Commit 5e274066e
(Always return absolute path in path_get_cdpath, 2019-10-17) tried to fix
all of them but it failed to do justice to its title. Let's fix this to
actually return absolute paths, always. Take care to to normalize the path
because it is used for autosuggestions. The normalization is mostly relevant
for CDPATH=. (the default) but it doesn't hurt others.
Closes#9407
It reads nicer to not have the "see also" thing right in the first
paragraph. I'm not even done reading this, why are you sending me
elsewhere?
(of course if it's a hotlink on a specific word that's different)
wopterr was a feature to allow wgetopt to emit error messages; but we do
not use this and never will. Remove its support. No functional change
expected here.
We wrongly highlight this as prefix when actually the trailing slash should
invalidate it. Turns out path normalization drops the slash, so let's
sidestep that.
Fixes#9394
The "flag" field enables an option to discover which flag it was invoked
with. However in practice none of our options use multiple flags so this
parameter was always nullptr. Remove it and fix up all the builtins to
stop passing this.
No functional change here.
I believe this should be identical to the previous code and handle the same
cases (I'm guessing going by the comment that this came from a C codebase
without `bool` types).
The problem with the previous code is that it tripped up the `clangd` analyzer
into thinking `assert()` expressions can/should be simplified via DeMorgan's to
improve readability (because it was seeing the fully expanded macro).
The tty_ownership test was sometimes failing. In this test,
`fish_test_helper` creates a child and transfers the tty to it,
"abandoning" the tty. In some cases, the child was running before the
parent; the child claims the tty. When the parent tries to transfer it to
the child, it get SIGTTIN and stops. Fix this by ignoring SIGTTIN and
SIGTTOU.
This only affects macOS and BSDs.
scp completions use "ls" to list files on the remote host. If a user aliases
them (in noninteractive shells) this will break. In general, this is the
users fault but also kind of ours because we shouldn't really use "ls" here.
Let's work around this problem by skipping functions.
Fixes#9363
Implement completion for vim tags from any place within the source tree.
To prevent freezes on a huge tags file (e.g., on one from the Linux
kernel source tree), amount of completion lines is limited to 10000.
Note that the TAGS file (EMACS-compatible tags file) is not searched
here as it would not be used by vim anyway.
