The characters ANY_CHAR, ANY_STRING, and ANY_STRING_RECURSIVE are
currently transformed by unescape, but not by escape. Let's try escaping
them. Fixes#1614.
Add the --wraps option to 'complete' and 'function'. This allows a
command to (recursively) inherit the completions of a wrapped command.
Fixes#393.
When evaluating a completion, we inspect the entire "wrap chain" for a
command, i.e. we follow the sequence of wrapping until we either hit a
loop (which we silently ignore) or the end of the chain. We then
evaluate completions as if the wrapping command were substituted with
the wrapped command. Currently this only works for commands, i.e.
'complete --command gco --wraps git\ checkout' won't work (that would
seem to encroaching on abbreviations anyways). It might be useful to
show an error message for that case.
The commandline builtin reflects the commandline with the wrapped
command substituted in, so e.g. git completions (which inspect the
command line) will just work. This sort of command line munging is
also performed by 'complete -C' so it's not totally without precedent.
'alias will also now mark its generated function as wrapping the
'target.
- Require all requests to use a session path.
- Use a redirect file to avoid exposing the '/start' URL on the
command line, as it contains the cookie value.
Fix for CVE-2014-2914.
Closes#1438.
Currently fish doesn't recognize toor as special. However, it's likely
that on BSD systems, fish shell will be used on toor, not on root (toor
is an intentionally existing account to use more advanced shell on, like
shell).
This stops unconditionally setting values for HOME and USER,
if we find those values in the environment. It also saves about 16KB
on OS X, which getpwuid allocates.
Instead of introducing a new local scope at the point of `set`, merely
push a new local scope at the end of env_init(). This means we have a
single toplevel local scope across the lifetime of the fish process,
which means that
set -l foo bar
echo $foo
behaves as expected, without modifying the global environment.
The mode restricts the scope in which the variable is searched for.
Use this new restricted scope functionality in the `set` builtin. This
fixes `set -g` to not show local shadowing variable values, and also
allows for scoped erasing of slices.
