# Chug
The fastest way to consume Homebrew bottles.
## Installation
```sh
cargo install chug-cli
```
## Usage
```sh
chug add $formula_name
chug remove $formula_name
chug update
```
## Rationale
[Homebrew](https://brew.sh/) is the de-facto standard package manager for 3rd-party development tools on macOS. Most of these tools are built using "formulae" and their pre-built binaries can be downloaded as "bottles". However, Homebrew still requires that users download a significant portion of the Homebrew toolchain to install bottles. Chug aims to improve on Homebrew in the following ways:
- Single-purpose
- Chug can only download and manage bottles
- Efficiency
- Chug is pre-compiled to a single binary (no more [Ruby DSLs](https://docs.brew.sh/Formula-Cookbook))
- Chug is written in Rust
- Chug downloads and extracts bottles in parallel
- Chug extracts bottles as they are being downloaded
- Chug avoids using external programs where practical
- Cleanliness
- Chug installs packages on a per-user basis
- Chug avoids changing permissions for `/usr/local`, `/opt/homebrew`, etc.
- Chug follows the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/latest) and installs binaries to `~/.local/bin` (configured via `$XDG_BIN_HOME`)
## TODO List
- [ ] Issues around patching on macOS (particularly for `python@3.13`)
- [ ] Linux support
## Non-goals
To keep this project fast and maintainable, the following are non-goals:
- Casks or building formulae from source
- Non-Homebrew sources
