The previous commit caused the tests to fail since env_remove() was
returning a blanket `!0` when a variable couldn't be unset because it
didn't exist in the first place. This caused the wrong message to be
emitted since the code clashed with a return code for `env_set()`.
Added `ENV_NOT_FOUND` to signify that the variable requested unset
didn't exist in the first place, but _not_ printing the error message
currently so as not to break existing behavior before checking if this
is something we want.
Variables set in if and while conditions are in the enclosing block, not
the if/while statement block. For example:
if set -l var (somecommand) ; end
echo $var
will now work as expected.
Fixes#4820. Fixes#1212.
fish reads paths out of /etc/paths.d. Prior to adbaddf it did
this on every shell invocation; with adbaddf it does so on only login
shells. This change wasn't justified so let's revert this behavior.
Currently, there are two possibilities for holes in the background:
- When there are two candidates with the same meaning (a long and a
short option or two candidates with the same description)
- When a candidate does not have a description (meaning the color
won't continue after it)
This changes both so the background just goes on.
In addition, it avoids making the background multiple times.
Fixes#4866.
The official fish documentation makes no mention of how `string split`
treats empty tokens, e.g. splitting 'key1##key2' on '#' or (more
confusingly) splitting '/path' on '/'. With this commit, `string split`
now has an option to exclude zero-length substrings from the resulting
array with a new `--no-empty/-n`. The default behavior of preserving
empty entries is kept so as to avoid breakage.
The two unicode glyphs used to represent missing new lines and redacted
characters for secure entry are both not present in the glyph tables of
the default font under Windows (Consolas and Lucida Console), use an
alternative glyph instead.
The "return" symbol is replaced with a pilcrow (¶) and the "redacted
character" symbol is replaced with a bullet (•). Both of these are
well-defined in almost all fonts as they're very old symbols. This
change only takes place if -DWSL is supplied by the build toolchain.
Note: this means a Windows SSH client connecting to a fish remote
instance on a non-Windows machine will still use the (unavailable)
default glyphs instead.
(and /etc/paths.d/*)
Do so by emulating the behavior of /usr/libexec/path_helper for login
shells, matching the behavior in /etc/profile.
Also add a path_helper command to reproduce the behavior of
/usr/libexec/path_helper for fish.
This also handles setting MANPATH if necessary.
Fixes issue #4336
* Completion for conda, the package manager
* Make the list of platforms a private variable
* Add commands activate and deactivate
* Avoid clobbering a user-defined function __
* Use Use __fish_seen_subcommand_from to identify subcommand
And treat the case of the first argument as a special case
with function __fish_conda_fist_arg
* Factor out create from loop for option --name
* Fix typo (missing parenthesis in description)
* Start from a blank state by removing completions from conda configuration script
* Make wcwidth configurable
This adds the cmake option "INTERNAL_WCWIDTH" (to be set to "ON" or
"OFF") and the configure option --[en,dis]able-internal-wcwidth.
Both default to enabling our fallback, but can be set to use the system's wcwidth again.
Sequel to #4554.
See #4571, #4539, #4609.
On my system, this would fix#4306.
The newly added `:` command is implemented as a function (to avoid
increasing complexity by making it a builtin), but it is saved to a path
that does not match its filename (since its name is somewhat of a
special character that might cause problems during installation).
Directly probing the `colon` function for autoload causes `:` to be
correctly loaded, so doing just that after function paths are loaded
upon startup.
This is a hack since the CPP code shouldn't really be aware of
individual functions, perhaps there is a better way of doing this.
no-op function for compatibility with sh, bash, and others.
Often used to insert a comment into a chain of commands without having
it eat up the remainder of the line, handy in Makefiles.
Fixes an issue introduced in 4414d5c888
where functions loaded from custom directories are not detected as being
valid for purposes of determining whether or not completions should be
called.
