we should maybe add some tests here to verify the logic wont be broken in the future. testing |
New function `_bash_it_homebrew_check()` sets global variable `$BASH_IT_HOMEBREW_PREFIX` using `brew --prefix` if `brew` exists as a valid command. If `brew` isn't installed, then return failure. Plugins can test for `brew` by calling this function and, if it succeeds, they can rely on `$BASH_IT_HOMEBREW_PREFIX` being defined properly.
Use new function `_bash_it_homebrew_check()` in existing plugins and completions which look for Homebrew. Alsö, use `$OSTYPE` instead of calling external `uname` binary.
Check if `brew` is installed every time, and *unset* `$BASH_IT_HOMEBREW_PREFIX` if not found. This accounts for the edge-case of a user _uninstalling_ Homebrew without restarting the shell.

Description
New function
_bash_it_homebrew_check()sets global variable$BASH_IT_HOMEBREW_PREFIXusingbrew --prefixifbrewexists as a valid command. Ifbrewisn't installed, then return failure.Plugins can test for
brewby calling this function and, if it succeeds, they can rely on$BASH_IT_HOMEBREW_PREFIXbeing defined properly.Motivation and Context
I already started looking at this before seeing that my PR fixes #1576. This is part of a patchset to reduce external binary invocations during shell startup. This patch doesn't actually call this function anywhere, on purpose. I don't want to load
rubyif none of the user's plugins need it.How Has This Been Tested?
Tested locally.
