⬆️ Bump2version

bump2version is a multi-language version bumper written entirely in 100% safe Rust, with no_std support and native Python and Node.js bindings 🗿.

🦀 Rust	🐍 Python	🟩 Node.js
`cargo add bump2version`	`pip install bump-rs`	`npm install bump2version`
Documentation	Read PYTHON.md	Read NODE.md

🤔 What does this crate provide?

bump2version automates semantic version management for any project regardless of language. It:

Parses version strings using a fully configurable regex (default: semver major.minor.patch).
Bumps any named component (major, minor, patch, or custom cyclic stages).
Rewrites version occurrences across multiple files, including multiline CHANGELOG patterns, using (?ms) DOTALL + MULTILINE semantics identical to Python's re.MULTILINE | re.DOTALL.
Commits and tags via 100% pure gix (gitoxide); zero subprocess calls, zero web-flow ghost-author bugs.
Reads author identity from the local git config.

🦀 Rust

The Rust crate is available on crates.io For a complete API…
