lcm

LCM is a tool for managing your system's configuration in Common Lisp. Think of it as Ansible, for your localhost, with Common Lisp instead of executable YAML. I wrote this because I needed a tool to provision my computers that lets me change from one configuration to another painlessly.

Features:

• Easily switch between multiple configurations.
• Factor out commonalities between different configurations.
• Imperative.

Concepts

A configuration has a name, and a list of components. A component is a discrete part of the configuration. A component can be a package that has to be installed, or a file that has to be created, or a shell command that has to be executed. Components are "bidirectional": they can be applied and then unapplied.

Applying a package component installs the package, applying a file component creates the file. Unapplying uninstalls the package and deletes the file, respectively.

Building

On Linux:

sudo apt-get install -y sbcl
mkdir -p ~/common-lisp # This is so that ASDF can find the project.
git clone https://github.com/eudoxia0/lcm.git ~/common-lisp/lcm
cd ~/common-lisp/lcm
make
sudo make install

You can then remove the ~/common-lisp directory.

Installation

curl -L -O https://github.com/eudoxia0/lcm/releases/download/v0.0.1/lcm
chmod +x lcm
mv lcm ~/.local/bin/lcm
