This package is now obsolete. It has been superceded by try-reflex.
NixOS users, please read the important note below before continuing
To install, do this:
git clone https://github.com/ryantrinkle/ghcjs-setup cd ghcjs-setup ./ghcjs-setup
This will install the Nix package manager, grab the ghcjs package information, build everything, then give you access to a sandbox with ghcjs and node.js available. The first time you run it, the build process will take a long time - up to several hours. After that, it should only take a few moments.
You will need sudo access in order to install Nix (unless you are on NixOS). However, you should run the script as yourself, not root - it will prompt for your password when necessary.
Note: Enabling the binary cache on NixOS
When using Nix on NixOS, only root can add binary caches to the system. This will force ghcjs-setup to rebuild GHCJS from scratch, which takes hours. To enable the binary cache, you can add the following line to your
nix.trustedBinaryCaches = [ "https://ryantrinkle.com:5443" ];
If you already have a trustedBinaryCaches option set up, just add
https://ryantrinkle.com:5443/ to the existing list.
Once it's been added, run
sudo -i nixos-rebuild switch to make the change take effect, then run ghcjs-setup as normal.
