upd-cli 0.0.5

A fast dependency updater for Python and Node.js projects

upd

A fast dependency updater for Python, Node.js, Rust, and Go projects, written in Rust.

Features

• Multi-ecosystem: Python, Node.js, Rust, and Go dependencies
• Fast: Parallel registry requests for all dependencies
• Constraint-aware: Respects version constraints like >=2.0,<3
• Smart caching: 24-hour version cache for faster subsequent runs
• Update filters: Filter by --major, --minor, or --patch updates
• Major warnings: Highlights breaking changes with (MAJOR)
• Format-preserving: Keeps formatting, comments, and structure
• Pre-release aware: Updates pre-releases to newer pre-releases
• Gitignore-aware: Respects .gitignore when discovering files

Installation

From crates.io

cargo install upd

From PyPI

pip install upd-cli
# or with uv
uv pip install upd-cli

From source

git clone https://github.com/rvben/upd
cd upd
cargo install --path .

Usage

# Update all dependency files in current directory
upd

# Update specific files or directories
upd requirements.txt pyproject.toml

# Dry-run mode (preview changes without writing)
upd -n
upd --dry-run

# Verbose output
upd -v
upd --verbose

# Disable colored output
upd --no-color

# Disable caching (force fresh lookups)
upd --no-cache

# Filter by update type
upd --major      # Show only major (breaking) updates
upd --minor      # Show only minor updates
upd --patch      # Show only patch updates

# Combine filters
upd --major --minor  # Show major and minor updates only

# Version precision
upd --full-precision  # Output full versions (e.g., 3.1.5 instead of 3.1)

Commands

# Show version
upd version

# Check for upd updates
upd self-update

# Clear version cache
upd clean-cache

Supported Files

Python

• requirements.txt, requirements-dev.txt, requirements-*.txt
• requirements.in, requirements-dev.in, requirements-*.in
• dev-requirements.txt, *-requirements.txt, *_requirements.txt
• pyproject.toml (PEP 621 and Poetry formats)

Node.js

• package.json (dependencies and devDependencies)

Rust

• Cargo.toml ([dependencies], [dev-dependencies], [build-dependencies])

Go

• go.mod (require blocks)

Example Output

pyproject.toml
  Would update requests 2.28.0 → 2.31.0
  Would update flask 2.2.0 → 3.0.0 (MAJOR)

Cargo.toml
  Would update serde 1.0.180 → 1.0.200
  Would update tokio 1.28.0 → 1.35.0

Would update 4 package(s) in 2 file(s), 15 up to date

Version Precision

By default, upd preserves version precision from the original file:

# Original file has 2-component versions
flask>=2.0        →  flask>=3.1        (not 3.1.5)
django>=4         →  django>=6         (not 6.0.0)

# Original file has 3-component versions
requests>=2.0.0   →  requests>=2.32.5

Use --full-precision to always output full semver versions:

upd --full-precision
flask>=2.0        →  flask>=3.1.5
django>=4         →  django>=6.0.0
requests>=2.0.0   →  requests>=2.32.5

Version Constraints

upd respects version constraints in your dependency files:

Constraint	Behavior
>=2.0,<3	Updates within 2.x range only
^2.0.0	Updates within 2.x range (npm/Cargo)
~2.0.0	Updates within 2.0.x range (npm)
>=2.0	Updates to any version >= 2.0
==2.0.0	No updates (pinned)

Caching

Version lookups are cached for 24 hours in:

• macOS: ~/Library/Caches/upd/versions.json
• Linux: ~/.cache/upd/versions.json
• Windows: %LOCALAPPDATA%\upd\versions.json

Use upd clean-cache to clear the cache, or upd --no-cache to bypass it.
