Odometer 🚀

A workspace version management tool that keeps package versions synchronized across projects.

Overview

Odometer provides intuitive commands to manage versions across project workspaces, with precise control over which packages get updated. Whether you need lockstep versioning for coordinated releases or independent versioning for different packages, odometer has you covered.

Currently supports: Rust/Cargo workspaces and Node.js/npm workspaces
Planned support: Python/pip and other package ecosystems

Key Features

• 🎯 Precise Package Selection - Target specific packages, all workspace members, or just the root
• 🔄 Flexible Version Strategies - Independent versioning or lockstep synchronization
• 🛡️ Safe Defaults - Operations target workspace root only unless explicitly specified
• 📊 Clear Inspection - See current versions and validate version fields
• 🏗️ Workspace Inheritance Support - Handles version = { workspace = true } (Cargo) and workspace:* (Node.js)
• ⚡ Fast & Reliable - Written in Rust with comprehensive test coverage

Installation

From crates.io (Recommended)

# Install latest stable release
cargo install odometer

# Or install specific version
cargo install odometer@0.3.1

From Source (Development)

git clone https://github.com/levicook/odometer.git
cd odometer
cargo install --path .

Verify Installation

odo --version
# Output: odometer 0.3.1

Multiple Binary Names

Odometer provides multiple binary names for convenience:

odo --help          # Short form (recommended)
odometer --help     # Full name
cargo odo --help    # Cargo subcommand style
cargo odometer --help

Quick Start

# See current versions
odo show

# Bump workspace root patch version
odo roll patch

# Bump all workspace members independently
odo roll --workspace patch

# Set all crates to same version (lockstep)
odo sync 1.0.0

# Validate all version fields
odo lint

Commands

odo show - Display Versions

Shows current versions for all workspace members:

$ odo show
workspace-root 1.0.0
lib1 0.5.2
lib2 0.3.1

odo roll - Increment Versions

Increment versions with precise control:

# Bump workspace root only (safe default)
odo roll patch              # 1.0.0 → 1.0.1
odo roll minor              # 1.0.1 → 1.1.0
odo roll major              # 1.1.0 → 2.0.0

# Custom increments
odo roll patch 5            # 2.0.0 → 2.0.5
odo roll patch -2           # 2.0.5 → 2.0.3

# Target all workspace members independently
odo roll --workspace patch  # Each crate's patch version increments

# Target specific packages
odo roll --package lib1 minor
odo roll -p lib1 -p lib2 patch

odo set - Set Specific Versions

Set exact versions for packages:

# Set workspace root to specific version
odo set 2.1.4

# Set specific packages
odo set 1.0.0 --package lib1
odo set 2.0.0 --workspace    # Set all workspace members

odo sync - Lockstep Synchronization

Set ALL workspace members to the same version:

# Synchronize everything to 1.0.0
odo sync 1.0.0

# After sync, all crates have identical versions
$ odo show
workspace-root 1.0.0
lib1 1.0.0
lib2 1.0.0

odo lint - Validate Versions

Check for missing or malformed version fields:

$ odo lint
✅ All workspace versions are valid

# Or with errors:
$ odo lint
❌ lib1: Invalid version 'not-a-version': unexpected character 'n' while parsing major version number

Package Selection

Odometer uses cargo-style package selection for precise control:

File and Directory Filtering

Odometer respects standard ignore patterns when discovering workspace members. By default, it follows the same conventions as tools like ripgrep and ag.

Default Behavior

• ✅ Hidden files ignored - Files/directories starting with . are skipped
• ✅ .gitignore respected - Standard git ignore patterns are followed
• ✅ .ignore respected - ripgrep/ag format ignore files are supported
• ✅ Global git ignore - ~/.config/git/ignore patterns are applied
• ✅ Local git exclude - .git/info/exclude patterns are applied

Override Flags

Control exactly what gets ignored with these flags:

Common Use Cases

# Include packages in hidden directories (e.g., .private-pkg)
odo show --hidden

# Debug: see everything odometer can find
odo show --no-ignore-all

# Ignore git patterns but respect custom .ignore files
odo sync 1.0.0 --no-ignore-git

# Work in a non-git directory with custom ignore patterns
odo lint --no-ignore-git --no-ignore-global

Ignore File Formats

Odometer supports these ignore files in order of precedence:

1. .ignore - ripgrep/ag format (highest precedence)
2. .gitignore - git format
3. Global git ignore - ~/.config/git/ignore (lowest precedence)

Example .ignore file:

# Ignore build artifacts
target/
node_modules/
dist/

# Ignore temporary packages
**/temp-*
**/.tmp

Example Workflows

Coordinated Release Workflow

# Get everything synchronized first
odo sync 1.0.0
odo show                    # Verify all at 1.0.0

# Now bulk operations work predictably
odo roll --workspace minor  # All: 1.0.0 → 1.1.0
odo lint                    # Validate everything

Independent Development Workflow

# Work on different features in different crates
odo roll --package app minor     # App gets new feature: 1.0.0 → 1.1.0
odo roll --package utils patch   # Utils gets bugfix: 0.5.0 → 0.5.1
odo show                         # See current state

# Bulk patch release when ready
odo roll --workspace patch       # Each crate gets patch bump

Preparing Major Release

# Review current state
odo show
odo lint

# Synchronize for coordinated release
odo sync 2.0.0
odo show                    # Confirm all at 2.0.0

Workspace Support

Odometer properly handles:

• Workspace roots with [workspace] sections (Cargo) or workspaces field (Node.js)
• Member packages in subdirectories
• Workspace inheritance:
  • Cargo: version = { workspace = true }
  • Node.js: "version": "workspace:*" or "version": "workspace:~"
• Mixed scenarios (some packages inherit, others don't)
• Single package projects (no workspace)
• Mixed ecosystems (Rust and Node.js packages in the same workspace)

Node.js Workspace Example

# Initialize a Node.js workspace
mkdir my-workspace && cd my-workspace
npm init -y
# Add workspaces to package.json
echo '{"workspaces": ["packages/*"]}' > package.json

# Create some packages
mkdir -p packages/pkg1 packages/pkg2
cd packages/pkg1 && npm init -y
cd ../pkg2 && npm init -y

# Now use odometer to manage versions
odo show                    # See all package versions
odo roll --workspace patch  # Bump all packages
odo sync 1.0.0             # Set all to same version

Rust Workspace Example

# Initialize a Rust workspace
cargo init --lib
# Add workspace configuration to Cargo.toml
echo '[workspace]
members = ["packages/*"]' >> Cargo.toml

# Create some crates
mkdir -p packages/crate1 packages/crate2
cd packages/crate1 && cargo init --lib
cd ../crate2 && cargo init --lib

# Now use odometer to manage versions
odo show                    # See all crate versions
odo roll --workspace patch  # Bump all crates
odo sync 1.0.0             # Set all to same version

Architecture

Odometer uses a clean architecture with three main layers:

• Domain (src/domain.rs) - Pure business logic for version operations
• IO (src/io/) - File system operations (currently Cargo, designed for Node.js/Python expansion)
• CLI (src/cli.rs) - Command-line interface and orchestration
