Important

This repository is archived and no longer maintained.

The version parser here does not implement Semantic Versioning precedence correctly (pre-release identifiers are ignored when ordering), and this problem is solved well by maintained libraries.

Use instead:

github.com/Masterminds/semver/v3 — parsing, comparison, and constraint matching (replaces Version and Constraint).

golang.org/x/mod/semver — if you only need to compare canonical vX.Y.Z strings.

The Migration up/down helper had no third-party equivalent and was only used by go/sqaffold (also archived). For database migrations use github.com/pressly/goose.

Go Version

A simple library for parsing and comparing versions according to Semantic Versioning 2.0.0.
