When the `Json` strategy was introduced, I forgot to also ensure that it's only treated as usable (in `Strategy#from_url`) if a `livecheck` block uses `strategy :json`. As a result, `Json` is incorrectly treated as a usable strategy for all formulae/casks that contain a `strategy` block. Since all of these `livecheck` blocks specify a strategy, this bug doesn't meaningfully impact livecheck's behavior (i.e., these checks continue to use their explicitly-specified strategy). The only practical difference is that `Json` incorrectly appears in the list of usable strategies in livecheck's verbose JSON output. This commit modifies `Strategy#from_url` to address this issue. The easiest way to enforce this rule involved passing in the `@strategies` key (a symbol) into the `select` block, so we can compare it to `livecheck_strategy` (the strategy symbol specified in the `livecheck` block).
Homebrew Ruby API
This is the API for Homebrew.
The main class you should look at is the {Formula} class (and classes linked from there). That's the class that's used to create Homebrew formulae (i.e. package descriptions). Assume anything else you stumble upon is private.
You may also find the Formula Cookbook and Ruby Style Guide helpful in creating formulae.
Good luck!
