semver-cli ·

A Rust CLI application for working with the semver specification

Motivation

node-semver can be noticeably slow if you're doing many parses. How much faster could it be if we just used some existing glue from rust's ecosystem?

I wrote a script that would parse my git history (to generate a CHANGELOG.md from commits + tags), eg:
bash changelog.sh 124cef4 57175e39d4e2c49a618668ac155f85b3585835b7 > CHANGELOG.md

time command execution on the above script (implemented with node-semver): real 1m7.698s user 0m45.112s sys 0m14.046s time command execution on the same script (using a debug version of this implementation): real 0m13.831s user 0m3.530s sys 0m4.337s time command execution on a --release build: real 0m10.202s user 0m2.527s sys 0m3.627s Fast!

Installation

cargo install semver-cli

Disclaimer

This is still very much a work in progress, see: Todo

Usage

validate: semver-cli 2.3.2 2.3.2 invalidate: semver-cli 100 -> no output increment: semver-cli 2.3.1 --increment 2.3.2 semver-cli 2.3.1 --increment=minor 2.4.0 semver-cli 2.3.1 --increment=major 3.0.0

Todo

• increment
• range
• preid
• loose
• include-prerelease
• coerce

(feature parity with https://github.com/npm/node-semver)
