Hammer Kerl

Hammer Kerl is a terminal-based menu-system around Kerl, the most excellent Erlang build and installation management system.

And while Kerl is indeed very excellent, I sometimes forget certain details about how kerl works (building, installing, and activating).

To alleviate some of my own confusions, I built Hammer Kerl as a tool to assist with the managing Kerl's most basic features, and so that when I forget a thing, the menu will help guide me.

Install

git clone https://github.com/choptastic/hammer_kerl

cd hammer_kerl

sudo make install

Usage

Once Hammer Kerl is installed, you can just run hammer_kerl from the terminal to see what it can do.

Additionally, after hammer_kerl is installed, if you run erl orescript and you'll be prompted with the Hammer Kerl menu if there is no kerl-activated version of Erlang. If, however, you've already have a kerl-activated Erlang installation, then Erlang will just run.

Features

• Download, Build, and Install versions of Erlang (from a list of available versions)
• Delete installed or built versions of Erlang
• Activate installed versions
• Auto-add the kerl activation scripts to your shell startup scripts (so you don't have to activate every time or mess about with the shell startup scripts yourself).

TODO

• Prompt to automatically install all dependencies.
