Constant Summary collapse

NAME_ARGUMENT =

An optional name: label may precede the url: argument.

/(?:name:\s+"[^"]+",\s*)?/
URL_ARGUMENT =

The url: argument identifies the dependency's source.

/url:\s+"(?<url>[^"]+)",\s*/
REQUIREMENT_ARGUMENT =

The version requirement (e.g. from: "1.0.0", .upToNextMajor(from: "1.0.0"), a range).

/(?<requirement>#{NativeRequirement::REGEXP})/
TRAILING_ARGUMENT =

A single additional labeled argument (e.g. traits: []) whose value may be an array, a string, or a bare token. The leading comma is optional so the final argument matches too.

/\s*,?\s*\w+\s*:\s*(?:\[[^\]]*\]|"[^"]*"|[^\s,)]+)/
TRAILING_ARGUMENTS =

After the requirement there may be any number of trailing arguments (which can span onto following lines) before the closing ), optionally followed by a trailing comma.

/(?:#{TRAILING_ARGUMENT})*\s*,?\s*/
DEPENDENCY = 
/(?<declaration>\.package\(\s*
 #{NAME_ARGUMENT}#{URL_ARGUMENT}#{REQUIREMENT_ARGUMENT}#{TRAILING_ARGUMENTS}
