bver 0.1.0

A bump-version tool for multi-language projects

Features

• Multi-format version support: Handles Python (PEP 440), Semver (npm/Cargo), and simple major.minor.patch versions
• Automatic version casting: Convert between version formats when needed (e.g., 1.2.3a1 to 1.2.3-alpha.1)
• Interactive TUI: Review and selectively apply version changes with a terminal UI
• Git integration: Automatic commits, tags, and pushes
• Pre-commit hook support: Run pre-commit hooks before committing version bumps
• Flexible configuration: Configure via bver.toml, pyproject.toml, package.json, or Cargo.toml

bver bump dev            # 1.2.3 -> 1.2.3.dev1

# Release (strip pre-release suffix)
bver bump release        # 1.2.3a1 -> 1.2.3

# Set explicit version
bver bump 2.0.0

# Force git operations (overwrite tags, force push)
bver bump patch --force

Configuration

Standalone (bver.toml)

current-version = "1.2.3"

# Optional settings
context-lines = 3              # Lines of context in diff preview
default-kind = "any"           # any | simple | python | semver
on-invalid-version = "error"   # error | cast

[git]
action = "commit-and-tag"      # disabled | commit | commit-and-tag | commit-tag-and-push
run-pre-commit = "when-present" # enabled | disabled | when-present
tag-template = "{new-version}" # Template for git tag name
commit-template = "Bump version from {current-version} to {new-version}"

[[file]]
src = "src/version.py"
kind = "python" # pep440

[[file]]
src = "package.json"
kind = "semver" # javascript, rust, ...

[[file]]
src = "test.txt"
kind = "simple" # strict major.minor.patch format.

Template Variables

The tag-template and commit-template settings support these variables:

• {current-version} - the version before bumping
• {new-version} - the version after bumping

Example: tag-template = "v{new-version}" produces tags like v1.2.3.

Python projects (pyproject.toml)

[project]
version = "1.2.3"

[tool.bver.git]
action = "commit-tag-and-push"

[[tool.bver.file]]
src = "src/mypackage/__init__.py"
kind = "python"

Node.js projects (package.json)

{
  "version": "1.2.3",
  "bver": {
    "git": {
      "action": "commit-and-tag"
    },
    "file": [
      { "src": "src/version.ts", "kind": "semver" }
    ]
  }
}

Rust projects (Cargo.toml)

[package]
version = "1.2.3"

[package.metadata.bver.git]
action = "commit-and-tag"

[[package.metadata.bver.file]]
src = "src/lib.rs"
kind = "semver"

Version Formats

Version Casting

When on-invalid-version = "cast", bver automatically converts versions between formats:

• To simple: Strips pre-release, post, dev, local, and epoch (1.2.3a1 -> 1.2.3)
• To semver: Converts Python pre-releases (1.2.3a1 -> 1.2.3-alpha.1)
• To python: Most formats are already valid PEP 440

TUI Controls

When bumping versions, an interactive TUI shows proposed changes:

Git Actions

Use --force to overwrite existing tags and force push.

A note on AI

• I just made AI write what I want my version bumper to be. The code in this project is entirely written by Claude. That being said, human contributions are also welcome 😉.
