This teaches the status command to work with features.
'status features' will show a table listing all known features and whether
they are currently on or off.
`status test-feature` will test an individual feature, setting the exit status to
0 if the feature is on, 1 if off, 2 if unknown.
This introduces a new type features_t that exposes feature flags. The intent
is to allow a deprecation/incremental adoption path. This is not a general
purpose configuration mechanism, but instead allows for compatibility during
the transition as features are added/removed.
Each feature has a user-presentable short name and a short description. Their
values are tracked in a struct features_t.
We start with one feature stderr_nocaret, but it's not hooked up yet.
As it turns out, for some terminals backspace is \b but only when
preceded by \e.
All this makes about as much sense as the english language.
Fixes#4955.
This was done in share/config.fish, but leads to surprising results if
that isn't read - e.g. because someone just built fish in the git
directory to test it without installing.
It's also not something that is any more or less complicated.
For compatibility, keep it in config.fish as well for the time being.
The previous completion generation was broken for several reasons:
* ./foo would break detection of suffix due to the leading . being
interpreted an extension marker,
* ./foo would be completed as foo, which would be excluded from
matching inrcomplete.cpp
Using `git for-each-ref` both simplifies the code (no need to deal
with detached heads anymore) and speeds it up.
With 1600 branches, the time goes from ~48ms to ~16ms.
- fix capitalization
- shorten descriptions
- implement subcommand shortcuts
- add arg completion for 'limit' and 'depth' switches
- improve arg completion for list subcommand in case of -p switch
bower was calling `__fish_should_complete_args`, the old name for
`__fish_should_complete_switches.`
yarn was parsing bower.json instead of package.json.
To be used by completions to directly determine whether it is either
possible or preferable to complete a switch (instead of a subcommand),
(presuming that switches must come before subcommands).
* __fish_can_complete_switches: we are in a position where a switch may
be placed.
* __fish_should_complete_switches: we're in a position to accept a
switch and the current token starts with `-` so we have no choice but
to do so.

`all-the-package-names` is still used to generate completions for `npm`
if it is installed, but it is not manually installed nor updated. It is
now the user's responsibility to do both, and it must be installed
globally.
`npm search` was _way_ too slow to be used for dynamic completions, so
using a cached list of all avaialable NPM packages to match against.
This is a bit brave for a fish completion, but the npm package
`all-the-package-names` has a list of, well, all the package names
avaialable for installation via the default npm registry. Installing a
copy locally to $HOME/.cache/fish/npm_completions and using that to
search for packages matching the tokenized command line.
Preference would be to call `__update_atpm` in the background, but that
emits an ugly "job has completed" message..
Should also use this for completions for `yarn add`.
Instead, attempt to extract the message that _would_ be displayed on
execution of `./configure --help` by relying on some markers present in
autoconf-generated configure files.
As measured with 'hyperfine' on a laptop running in reduced frequency
power savings mode, `fish -c "__fish_parse_configure ./configure"`
runtime dropped from ~1.25s to ~0.8ms, which is inline with the
previously observed ~350ms execution time for `./configure --help`.
fish's own startup time is approximately 75ms before parsing begins.
Still very slow, but much better.
