VersionRange

A range of versions (node-semver's grammar in one spelling): ^1.2.3, >=1.0.0 <2.0.0, 1.2.x || >=2.5.0-beta.1.

Software; not ordered; since Jadpo 0.1.0.

Make one

Build one from its text, VersionRange("^1.2.3"), which checks it: text that isn't one breaks format.

text.parse(raw, as: VersionRange) reads one from its text; text that isn't one at all fails malformed, such as ^v1.2.3, =1.2.3 or >= 1.0.0.

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

It is stored in one column named for the field, of type text. 1.2.x || >=2.5.0-beta.1 is stored as '1.2.x || >=2.5.0-beta.1'.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Operations

• semver.satisfies(version: SemanticVersion, range: VersionRange) -> Bool: Whether version is inside range, as node-semver reads the range: in one of its sets joined by ||, meeting each comparison of it. A pre-release is inside only where a comparison of that set names a pre-release of the same major, minor and patch, so ^1.2.3 never takes 2.0.0-beta.1.

Like every standard type, it also has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
