# Semantic Version Parsing with Named Groups
# Parse major, minor, patch, pre-release, build from version strings
# Basic SemVer
# Pattern: v?(?<major>0|[1-9]\d*)\.(?<minor>0|[1-9]\d*)\.(?<patch>0|[1-9]\d*)
# Input: v2.1.0
# Groups: major=2, minor=1, patch=0

# SemVer with Pre-release
# Pattern: v?(?<major>0|[1-9]\d*)\.(?<minor>0|[1-9]\d*)\.(?<patch>0|[1-9]\d*)(?:-(?<pre>[0-9A-Za-z-]+(?:\.[0-9A-Za-z-]+)*))?
# Input: 2.0.0-alpha.1
# Groups: major=2, minor=0, patch=0, pre=alpha.1
