Class: Livecheck
Overview
The Livecheck class implements the DSL methods used in a formula’s, cask’s
or resource’s livecheck
block and stores related instance variables. Most
of these methods also return the related instance variable when no argument
is provided.
This information is used by the brew livecheck
command to control its
behavior. Example livecheck
blocks can be found in the
brew livecheck
documentation.

Instance Method Details
#cask(cask_name = T.unsafe(nil)) ⇒ String?
Sets the @referenced_cask_name
instance variable to the provided String
or returns the @referenced_cask_name
instance variable when no argument
is provided. Inherited livecheck values from the referenced cask
(e.g. regex) can be overridden in the livecheck block.

#formula(formula_name = T.unsafe(nil)) ⇒ String?
Sets the @referenced_formula_name
instance variable to the provided
String
or returns the @referenced_formula_name
instance variable when
no argument is provided. Inherited livecheck values from the referenced
formula (e.g. regex) can be overridden in the livecheck block.

#regex(pattern = T.unsafe(nil)) ⇒ Regexp?
Sets the @regex
instance variable to the provided Regexp
or returns the
@regex
instance variable when no argument is provided.

# File 'livecheck.rb', line 81 def regex(pattern = T.unsafe(nil)) case pattern when nil @regex when Regexp @regex = pattern end end |
#skip(skip_msg = T.unsafe(nil)) ⇒ Boolean
Sets the @skip
instance variable to true
and sets the @skip_msg
instance variable if a String
is provided. @skip
is used to indicate
that the formula/cask/resource should be skipped and the skip_msg
very
briefly describes why it is skipped (e.g. “No longer developed or
maintained”).

# File 'livecheck.rb', line 101 def skip(skip_msg = T.unsafe(nil)) @skip_msg = skip_msg if skip_msg.is_a?(String) @skip = true end |
#skip? ⇒ Boolean
Should livecheck
skip this formula/cask/resource?

# File 'livecheck.rb', line 109 def skip? @skip end |
#strategy(symbol = T.unsafe(nil), &block) ⇒ Symbol?
Sets the @strategy
instance variable to the provided Symbol
or returns
the @strategy
instance variable when no argument is provided. The strategy
symbols use snake case (e.g. :page_match
) and correspond to the strategy
file name.

#to_hash ⇒ Hash{String => T.untyped}
Returns a Hash
of all instance variable values.

#url(url = T.unsafe(nil)) ⇒ String, ...
Sets the @url
instance variable to the provided argument or returns the
@url
instance variable when no argument is provided. The argument can be
a String
(a URL) or a supported Symbol
corresponding to a URL in the
formula/cask/resource (e.g. :stable
, :homepage
, :head
, :url
).
