copit 0.2.1

Copy reusable source code from GitHub repos, HTTP URLs, and ZIP archives into your project

copit

Copy reusable source code from GitHub repos, HTTP URLs, and ZIP archives into your project.

Inspired by shadcn/ui — instead of installing opaque packages, copit copies source code directly into your codebase. The code is yours: readable, modifiable, and fully owned. No hidden abstractions, no dependency lock-in. Override anything, keep what you need.

Use cases

• Quickly copy and own code — Pull files from GitHub repos, HTTP URLs, or ZIP archives directly into your project. No forks, no submodules — just your own copy to read, modify, and maintain.

• Build frameworks with injectable components — Create a core library as a traditional package, then offer optional components that users copy into their projects via copit. Think of how shadcn/ui is built on top of Tailwind and Radix UI: the base libraries are installed as dependencies, while UI components are copied in and fully owned. Apply the same pattern to any ecosystem — a LangChain-style core as a library, with community integrations (OpenAI, Anthropic, etc.) as injectable source code that users can customize freely.

For PyPI: pip uninstall copit. For Cargo: cargo uninstall copit.

Quick start

# Initialize a copit.toml in your project
copit init

# Copy a file from a GitHub repo
copit add github:serde-rs/serde@v1.0.219/serde/src/lib.rs

# Copy a file from a raw URL
copit add https://raw.githubusercontent.com/serde-rs/serde/refs/heads/master/LICENSE-MIT

# Copy from a ZIP archive
copit add https://example.com/archive.zip#src/utils.rs

Usage

copit init

Creates a copit.toml config file in the current directory with a default target directory (vendor).

copit add <source>...

Fetches source code and copies it into your project.

Usage: copit add [OPTIONS] [SOURCES]...

Arguments:
  [SOURCES]...  Source(s) to add (e.g., github:owner/repo@ref/path, https://...)

Options:
      --to <TO>    Target directory to copy files into
      --overwrite  Overwrite existing files without prompting
      --skip       Skip existing files without prompting
      --backup     Save .orig copy of new version for excluded modified files

Source formats

Format	Example
GitHub	github:owner/repo@ref/path/to/file (alias: gh:)
HTTP URL	https://example.com/file.txt
ZIP archive	https://example.com/archive.zip#inner/path

copit update <path>...

Re-fetches specific tracked source(s) by path (as shown in copit.toml). Always overwrites non-excluded files.

# Re-fetch a specific tracked source
copit update vendor/mylib

# Re-fetch with a new version
copit update vendor/mylib --ref v2.0

# Re-fetch with backup for excluded modified files
copit update vendor/mylib --backup

Options:

• --ref <version> — Override the version ref for this update (updates the source string and ref field)
• --backup — Save .orig copy of new version for excluded modified files

copit sync

Re-fetches all tracked sources in copit.toml.

# Re-fetch all tracked sources
copit sync

# Re-fetch all with backup for excluded modified files
copit sync --backup

Options:

• --ref <version> — Override the version ref (errors if multiple sources are tracked)
• --backup — Save .orig copy of new version for excluded modified files

copit remove <path>... (alias: rm)

Removes previously copied files from disk and their entries from copit.toml.

# Remove a specific file
copit remove vendor/lib.rs

# Remove multiple files
copit rm vendor/lib.rs vendor/utils.rs

# Remove all tracked sources
copit rm --all

Config file

copit.toml tracks your project's target directory and all copied sources:

[project]
target = "vendor"

[[sources]]
path = "vendor/prek-identify"
source = "github:j178/prek@master/crates/prek-identify"
ref = "master"
commit = "abc123def456..."
copied_at = "2026-03-07T08:46:51Z"
exclude_modified = ["Cargo.toml", "src/lib.rs"]

• ref: The user-specified version string (branch/tag/sha)
• commit: Resolved commit SHA from GitHub API (optional, GitHub sources only)
• exclude_modified: List of relative paths (within source folder) to skip on re-add. With --backup, the new version is saved as <file>.orig.
