Switch from null terminated arrays to `wcstring_list_t` for lists of
special env var names. Rename `list_contains_string` to `contains` and
modify the latter interface to not rely on a `#define`.
Rename `list_contains_string()` to `contains()` and eliminate the
current variadic implementation. Update all callers of the removed
version to use the string list version.
There are at least three env vars describing a sequence of paths to be
searched where an empty path element is implicitly equivalent to ".".
This change converts the implicit "." to explicit whenever the variable
is imported or set. This makes the variable much easier to use in fish
scripts.
Fixes#3914
- Error out if anything that is not a PID is given
- Otherwise background all matching existing jobs, even if not all
PIDs exist (but print a message for the non-existing ones)
Fixes#3909.
We've gotten feedback from the Stackexchange team that too many fish
questions asked on stackoverflow don't really belong there. So clarify
the README to also point users at superuser for questions not related to
fish script.
A call to default_vars_path() takes the environment variable
lock while the uvars lock is held. Ensure that doesn't happen by
deferring the uvars lock to later in the function.
cached_esc_sequences_t::find_entry was constructing a wcstring
from a c string, using lengths longer than the length of the cstring.
Detected with asan.
In the process of fixing the issue I decided it didn't make sense to
have two, incompatible, ways of converting variable strings to arrays.
Especially since the one I'm removing does not return empty array elements.
Fixes#2106
This is to make pasting literals easier.
When a user pastes something, we normally take it as-is.
The exception is when a single-quote is open, e.g. the current token
is
foo'bar
When something is pasted here, we escape single-quotes (`'`) and
backslashes (`\\`), so typing a `'` after it will turn it into a
literal token.
Fixes#967.
