Module parse 

Loose semver parsing helpers.

Strict SemVer 2.0.0 does not allow a leading v (or similar). In practice many tools publish tags like v1.2.3, v.1.2.3, or v:1.2.3. Loose mode strips a single leading prefix of that form before parsing.

Functions

normalize_loose_range

Normalize a version requirement for loose parsing by stripping v/V (optionally followed by ., :, -, or _) before version numbers at comparator boundaries.

parse_version

Parse a version string, optionally accepting a loose leading prefix.

parse_version_req

Parse a version requirement string, optionally accepting loose version prefixes.

strip_loose_version_prefix

Strip a loose leading version prefix: v/V, optionally followed by ., :, -, or _, only when the remainder starts with a digit.
