This adds a new capability to the `set` command. It is similar to
running `set` with no other arguments but provides far more detail about
each variable. Such as whether it is set in each of the local, global,
and universal scopes. And the values in each scope. You can also ask for
specific variables to be shown.
Fixes#4265
Rewrite the `abbr` function to store each abbreviation in a separate
variable. This greatly improves the efficiency. For the common case
it is 5x faster. For pathological cases it is upwards of 100x faster.
Most people should be able to unconditionally define abbreviations in
their config.fish without a noticable slow down.
Fixes#4048
This takes a string that is then split upon like `string split`.
Unlike $IFS, the string is used as one piece, not a set of characters.
There is still a fallback to IFS if no delimiter is given, that
behaves exactly as before.
Fixes#4156.
This silences warnings from the compiler about ignoring return value of
‘ssize_t write(int, const void*, size_t)’, declared with attribute
warn_unused_result [-Wunused-result].
The class `completer_t` declares `complete_special_cd`, an unused method. I searched the entire source tree and this declaration seems to be the only instance of `complete_special_cd`. There is no definition or uses which likely means this is dead code.
PR #3691 made most calls to `signal_block()` and `signal_unblock()`
no-ops unless a magic env var is set when fish starts running. It's
been seven months since that change was made and no problems have been
reported. This finishes that work by removing those no-op function calls
and support for the magic env var in our next major release (which won't
happen till at least six months from now).
The primary motivation for --keep-order for `complete` was to support
something like commit history completions, which are returned by git in
reverse chronological order and make no sense alphabetically (they are
SHA1 hashes).
See https://github.com/fish-shell/fish-shell/issues/361 for more info.
Introduce a -k/--keep-order switch to `complete` that can be used to
prevent fish from sorting/re-ordering the results provided by a completion
source.
In addition, this patch does so without doing away with deduplication
of completions by introducing a new unique_unsorted(..) helper function
that removes duplicates in-place without affecting the general order of
the vector/container.
Note that the code now uses a stable sort for completions, since the
behavior of is_naturally_less_than as of this patch now means that the
results are not necessarily _actually_ identical just because that function
repeatedly returns false for any ordering of any given two elements.
Fixes#361
* Make npm run-script completion faster with `jq`
When jq is available, it's actually faster to invoke jq and parse the `package.json`
invoking the `npm` command.
Also, prior to this commit, both `__fish_complete_npm` and `__fish_npm_run` were being run
whenever completions for `npm run` subcommand was being used, which was actually making
repetitive work (invoking npm command twice). This pull request is supposed to make completion
without `jq` faster as well
* Refactor npm.fish for code reutilization
Created function to handle both cases of npm run completion parse, with or without `jq` completion.
* Remove unecessary blank line
This completes the refactoring of the `set` builtin. It also removes a
seemingly never used feature of the `set` command. It also eliminates all
the lint warnings about this module.
Fixes#4236
When reporting whether a boolean flag was seen report the actual flags
rather than a summary count. For example, if you have option spec `h/help`
and we parse `-h --help -h` don't do the equivalent of `set _flag_h 3`
do `set _flag_h -h --help -h`.
Partial fix for #4226
When executing a function, local-exported (`set -lx`) variables
previously were not accessible at all. This is weird e.g. in case of
aliases, since
```fish
set -lx PAGER cat
git something # which will call $PAGER
```
would not work if `git` were a function, even if that ends up calling
`command git`.
Now, we copy these variables, so functions get a local-exported copy.
```fish
function x
echo $var
set var wurst
echo $var
end
set -lx var banana
x # prints "banana" and "wurst"
echo $var # prints "banana"
```
One weirdness here is that, if a variable is both local and global,
the local-copy takes precedence:
```fish
set -gx var banana
set -lx var pineapple
echo $var # prints "pineapple"
x # from above, prints "pineapple" and "wurst"
echo $var # still prints "pineapple"
set -el var # deletes local version
echo $var # "banana" again
```
I don't think there is any more consistent way to handle this - the
local version is the one that is accessed first, so it should also be
written to first.
Global-exported variables are _not_ copied, instead they still offer
full read-write access.
