go-versions

The version scheme real packages actually use — a faithful Go port of pkgx's, for the versions strict semver rejects.

The real world ships many “almost valid” versions — 1.1.1w and its kin — that node-semver and the Go semver libraries simply refuse. A package manager cannot refuse them back, so it needs a scheme that accepts what upstreams actually publish.

This is that scheme, ported faithfully rather than approximated, and it is the parsing and comparison implementation behind the go-pkgx family.

semver.ParseVersion("1.1.1w") — openssl-style and the rest of what pkgx accepts, with the same ordering.

Faithful means tested against the reference behaviour, not merely inspired by it — the point of a port is that it agrees with the original on the awkward inputs, which are the only ones that matter here.
