## What it is
A Go library for parsing, comparing, sorting, and constraining Semantic Versions. It supports strict SemVer 2.0 parsing, coercion of loose versions, and constraint checks with tilde and caret ranges.

## Use cases
- parse semantic versions in go
- compare version numbers in go
- check if a version satisfies constraints like ^1.2.0
- sort a list of versions
- handle versions with a v prefix
- validate semver strings

## When to choose
- you need robust semver parsing and constraint checking in a Go project
- you need tilde/caret range compatibility with other ecosystems' tooling
- you want a mature, widely used library (used by Helm and dep)

## When to avoid
- you need version handling in a language other than Go
- you need full non-semver version scheme support (e.g., arbitrary versioning schemes)

## Facets
- artifact type: library
- maturity: active
- function: parser, developer-tools
- domain: developer-tools, version-control
- platform: go
- tags: semver, semantic-versioning, version-constraints, version-comparison, algorithms
