#livecheck(&block) ⇒ Object

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Livecheck can be used to check for newer versions of the software. This method evaluates the DSL specified in the livecheck block of the Resource (if it exists) and sets the instance variables of a Livecheck object accordingly. This is used by brew livecheck to check for newer versions of the software.

Example

livecheck do
  url "https://example.com/foo/releases"
  regex /foo-(\d+(?:\.\d+)+)\.tar/
end

#stage(target = nil, debug_symbols: false, &block) ⇒ Object

Verifies download and unpacks it. The block may call |resource, staging| staging.retain! to retain the staging directory. Subclasses that override stage should implement the tmp dir using Mktemp so that works with all subtypes.

Raises:

If a target is given, unpack there; else unpack to a temp folder. If block is given, yield to that block with |stage|, where stage is a ResourceStageContext. A target or a block must be given, but not both.
