These are short flags for "--perm=read" and "--type=link" and such.
Not every type or permission has a shorthand - we don't want "-s" for
"suid". So just the big three each get one.
This is needed because you might feasibly give e.g. `path filter`
globs to further match, and they might already present no results.
It's also well-handled since path simply does nothing if given no paths.
These were officially called "--null-input", but I just used
"--null-in" everywhere, which worked because getopt allows unambiguous abbreviations.
But since *I* couldn't keep it straight and the "put" is just
superfluous, let's remove it.
This is theoretically sound, because a path can only be PATH_MAX - 1
bytes long, so at least the PATH_MAXest byte needs to be a NULL.
The one case this could break is when something has a NULL-output mode
but doesn't bother printing the NULL for only one path, and that path
contains a newline. So we leave --null-in there, to force it on.
This adds a "path" builtin that can handle paths.
Implemented so far:
- "path filter PATHS", filters paths according to existence and optionally type and permissions
- "path base" and "path dir", run basename and dirname, respectively
- "path extension PATHS", prints the extension, if any
- "path strip-extension", prints the path without the extension
- "path normalize PATHS", normalizes paths - removing "/./" components
- and such.
- "path real", does realpath - i.e. normalizing *and* link resolution.
Some of these - base, dir, {strip-,}extension and normalize operate on the paths only as strings, so they handle nonexistent paths. filter and real ignore any nonexistent paths.
All output is split explicitly, so paths with newlines in them are
handled correctly. Alternatively, all subcommands have a "--null-input"/"-z" and "--null-output"/"-Z" option to handle null-terminated input and create null-terminated output. So
find . -print0 | path base -z
prints the basename of all files in the current directory,
recursively.
With "-Z" it also prints it null-separated.
(if stdout is going to a command substitution, we probably want to
skip this)
All subcommands also have a "-q"/"--quiet" flag that tells them to skip output. They return true "when something happened". For match/filter that's when a file passed, for "base"/"dir"/"extension"/"strip-extension" that's when something about the path *changed*.
Filtering
---------
`filter` supports all the file*types* `test` has - "dir", "file", "link", "block"..., as well as the permissions - "read", "write", "exec" and things like "suid".
It is missing the tty check and the check for the file being non-empty. The former is best done via `isatty`, the latter I don't think I've ever seen used.
There currently is no way to only get "real" files, i.e. ignore links pointing to files.
Examples
--------
> path real /bin///sh
/usr/bin/bash
> path extension foo.mp4
mp4
> path extension ~/.config
(nothing, because ".config" isn't an extension.)
edit_command_buffer uses the "norm" command for moving the cursor to a column
with the "|" primitive. The problem is that the user can remap "|". Fix this
by using the "norm!" variant which ignores user mappings (see ":h norm").
Closes#8971
git had a CVE related to arbitrary code being run when you run git status and similar, and instead of doing something about those arbitrary code bits they decided to lock it down entirely.
So now git will refuse to do basically anything once it detects the .git directory is owned by someone else.
So, what we do is:
If `git describe` failed with a status of 128, we keep an already
built version file.
This is an awful hack, but should help with the normal `cmake; make; sudo
make install` cycle.
(the only *real* way around this seems to be to not attempt to rebuild
the version file at install time entirely, but I have no idea how to
do that)
Fixes#8973.
With sphinx 4.5.0:
1. Some of our builtins actually give results (cd, end, set)
2. Some give broken results (and, if, or)
3. Only "for" even triggers the help page we hacked in
So this is of dubious use, and removing it gets us out of the awkward situation of shipping it.
Plus upstream sphinx has ditched jquery, so we would have to rewrite it anyway.
Like `set` and `read` before it, `eval` can be used to set variables,
and so it can't be shadowed by a function without loss of
functionality.
So this forbids it.
Incidentally, this means we will no longer try to autoload an
`eval.fish` file that's left over from an old version, which would
have helped with #8963.
Previously, running `fish_add_path /foo /foo` would result in /foo
being added to $PATH twice.
Now we check that it hasn't already been given, so we skip the
second (and any further) occurence.

This concerns what happens if one event handler removes another, when
both are responding to the same event. Previously we had a "double lock"
where we would traverse the list twice. Now track directly in the
handler when it is removed; this simplifies the code a lot. No
functional changes expected here.
Hitting tab on "echo **" will often result in more than 256 matches.
Commit 143757e8c (Expand wildcards on tab, 2021-11-27) describes this scenario
> If the expansion would produce more than 256 items, we flash the command
> line and do nothing, since it would make the commandline overfull.
Yet we actually erase the "**" token, which seems wrong since we already
flash the command line. Fix this, at the cost of making the code a bit uglier.
I tried to write a test in tests/pexpects/wildcard_tab.py but that doesn't
seem to work because pexpect provides only a "dumb" terminal. I wonder if we
can test what we write to the screen without depending on a terminal emulator.
`wg show` command shows entire interfaces configuration, not just the
list. This breaks completion when running fish from root, because
command output looks like this:
interface: wg0

private key: (hidden)
listening port: 12345

To show just the list of active interfaces, `wg show interfaces` should
be used instead.
man-db's man 2.7 as shipped in OpenSUSE fails to set a non-zero
exit code when invoked like "man ls-some/dir". This means
that we fail to display the man page if the commandline is
"ls some/dir". Work around this by never treating tokens
with slashes as subcommand.
