This adds a
brew style
linter to make sure that our generated Homebrew formulas will pass Homebrew'sbrew style
for users who have enabled Homebrew's default CI setup for their taps.I've also ensured our snapshots contain the auto-restyled copies afterbrew style --fix
is run.This required one stylistic change: the hashmap for binary aliases would violate the line length lint, and unfortunately Rubocop's line length autoformatter was consistently getting the formatting wrong. This instead (ab)uses the fact that JSON hashmaps have a compatible syntax to Ruby 1.9+ hashmaps so long as symbols are the keys - and we were already using symbolized keys. We can therefore use jinja's
tojson
with an indent to enable pretty-printing.
