ryantrinkle / ghcjs-setup

GHCJS installer and build tool based on Nix package manager

IMPORTANT

This package is now obsolete. It has been superceded by try-reflex.

ghcjs-setup

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 /etc/nixos/configuration.nix:

  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.

Packages added in shell.nix require rebuilding ghc and ghcjs

I'm not sure whether this is a documentation issue or a "bug" per se; I'm not yet familiar enough with Nix. (I am running NixOS in a VM.)

shell.nix has a comment: # Add Haskell packages to your environment here. After successfully running ghcjs-setup unmodified, I tried adding, e.g. lens on the next line. This seems to require rebuilding both ghc and ghcjs from source, which is beyond the capability of my VM:

[christian@nixos:~/ghcjs-setup]$ nix-shell
these derivations will be built:
  /nix/store/h8gbz8hfpvc86gsndkpr8166v86wrv5y-ghc-7.10.0.20150123.drv
  /nix/store/y711v3jbxkr21ny9snmmak5ysvk8d1rq-ghcjs-0.1.0.drv
these paths will be fetched (0.00 MiB download, 39.39 MiB unpacked):
  /nix/store/07azljpiya0h4jcw6nvxb9vbjdnp4vcw-haskell-lens-4.7
  [other dependencies]

(And it starts downloading cached binaries from https://ryantrinkle.com:5443/.)

Is this the expected behavior, i.e. not using the same ghc/ghcjs builds in non-ghcjs-setup usage?

(By the way, what I actually want to do is build the derivation for ocharles's virtual-dom with a command ala NIX_PATH=nixpkgs=/home/$USER/ghcjs-setup/nixpkgs/ nix-shell, which gives the same sort of result.)

Use upstream nixpkgs

I've been having problems with compiling some packages because the shipped version of GHC 7.10 had a bug. When I pulled the latest nixpkgs from https://github.com/NixOS/nixpkgs and re-run the script I've got a nice working GHC 7.10.1 install with the needed bugfixes.

Why not use upstream nixpkgs?

Add instructions for using the cache server on NixOS

Network Issues with ryantrinkle.com

I'm not completely sure this should be reported as a problem, but I'm going to do it for posterity at least. The interesting line seems to be curl: (6) Couldn't resolve host 'ryantrinkle.com'. When I retry, then it works for a little while longer, until it eventually hits the same error again, but for a different "derivation". There's a chance it's my local connection, but that seems somewhat unlikely.

I'm going to just keep trying until everything downloads, but there might be an issue with one of the servers.

This script is amazing by the way. Thanks so much.
