Install with Package Manager

yum

$ sudo yum install https://git.io/egison.x86_64.rpm https://git.io/egison-tutorial.x86_64.rpm

dpkg

$ wget https://git.io/egison.x86_64.deb https://git.io/egison-tutorial.x86_64.deb
$ sudo dpkg -i ./egison*.deb

Homebrew

$ brew update
$ brew tap egison/egison
$ brew install egison egison-tutorial

Install from Haskell Platform

1. Install Haskell Platform

To install Egison, you need to install Haskell Platform. This is because Egison is implemented in Haskell and distributed as a Hackage package.

If you use apt-get, execute the following commands.

$ sudo apt-get update
$ sudo apt-get install haskell-platform libncurses5-dev

Otherwise, download an installer from here.

2. Install Egison via Hackage

After you installed Haskell Platform, perform the following commands in the terminal.

$ cabal update
$ cabal install egison egison-tutorial
...
Installing executable(s) in /home/xxx/.cabal/bin
Registering egison-X.X.X...

When the installation is finished, there will be a message that tells the location of the installed binary. Add the path to the $PATH vairable so that your shell can find the egison command. For example, if you are using bash, run the following commands.

$ echo "PATH=\$PATH:/home/xxx/.cabal/bin" >> ~/.bashrc
$ source ~/.bashrc
