- Don't write to disk, just pipe. - Don't loop, just do all functions. Performance of old implementation on my system: ``` real 0m9.996s user 0m5.318s sys 0m9.126s ``` Performance of new implementation on my system: ``` real 0m0.052s user 0m0.069s sys 0m0.025s ```
The weird subshell is weird AF. Just do a normal `if`. Ditto `_binary_exists()`, `_completion_exists()`, and `_is_function()`!
Quote things, SC2268, SC2143, SC2181, SC2162, SC2016, SC2013, &c. Rewrite globbing per `shellcheck`’s SC2013, and alsö s/typeset/local/g. Eliminate `compgen` where possible. Alsö: use the existing utility functions `_bash-it-get-component-type-from-path` and `_bash-it-get-component-name-from-path`, which just use parameter substitution anyway. Why was `sed` here? Alsö, don't add not-existing directories to `$PATH` in `pathmunge()`. Finally, merge PR Bash-it#1865 from NoahGorny...and clean it a bit...
lib/helpers: lint `_bash-it-migrate()` lib/helpers: lint `_disable-thing()` lib/helpers: lint `_enable-thing()` lib/helpers: lint `_help-list-aliases()` lib/helpers: lint `_help-plugins()` lib/helpers: some SC2034 fixes And SC2154 in `_make_reload_alias()` lib/helpers: lint `all_groups()`
My apologies to future `git blame` hunters ♥
- Improve `pushd`/`popd` somewhat - local some parameters - Lose weird Mac-specific alternate shell startup file (Bash loads startup files on Mac the same as it does on any other *nix system.)
Use `_bash-it-component-item-is-enabled()` Fix SC2295
Use curly braces when `$1` is unseparated from words in a string.

Replace weird non-globs with array and loop, as suggested by `shellcheck`. Alsö, simplify several constructs to eliminate external binaries. Alsö, see mvdan/sh issue 558 lib/helpers: unbound positional parameters
- add some `local` variables, - don't subshell `_typeset_functions`,
Duplicate function of existing `_bash-it-component-item-is-enabled()`.
Quote some parameter uses that don't strictly require it, but since Bash needs so many quotes everywhere else my brain worms feel better when these are quoted too. lib/helpers: simplify some quote escapes

Description
This is a partial PR covering only the
lib/helpersportion of #1917 in support of #1696 and fixes #1978.This PR touches many files due to some scope overlap with
lib/utilitiesand due to touching BATS: I needed to add several.keepfiles to protect empty folders fromgit.Closes #1978.
Motivation and Context
My
shellcheckbranch (#1917) got a bit large, so I'm splitting it up. This PR includes only changes tolib/helpers(and a littlelib/utilities):_is_functionbehave similarly to_command_exists,_completion_exists,_binary_exists, &c.pathmungenot add not-existing directories to$PATH_bash-it-get-component-type-from-path()and...name-from-path()all_groups()from 10 seconds to run to less than one tenth of a second.plugin/rubyas they weren't working on Mac OS X, turns out due to the fact that we set$HOMEto$TMPDIRin our test suite on Mac, which I only figured out after messing around with BATS quite a bit._bash-it-component-item-is-enabled()not rely on reading every single file from disk, parsing metadata, then grep and awk.How Has This Been Tested?
The full test suite and
shellcheckhave run on #1917 and this is part of my main branch since september.Types of changes
