### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. 
###.   Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of 
###.   things to watch out for:
###      - Check out the `nix-darwin` instructions, as they have changed.
###      - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.

Using Docker for Rouge development

Docker can be used to avoid having to install Ruby and all the dependencies locally.

Clone the project first, and navigate into your clone:

$ git clone https://github.com/jneen/rouge.git
$ cd rouge

General notes

• nix-channel and ~/.nix-defexpr are gone. We'll use $NIX_PATH (or user environment specific overrides configured via nix set-path) to look up packages. Since $NIX_PATH supports URLs nowadays, this removes the need for channels: you can just set $NIX_PATH to e.g. https://nixos.org/channels/nixos-15.09/nixexprs.tar.xz and stay up to date automatically.

• By default, packages are selected by attribute name, rather than the name attribute. Thus nix install hello is basically equivalent to nix-env -iA hello. The attribute name is recorded in the user environment manifest and used in upgrades. Thus (at least by default) hello won't be upgraded to helloVariant.

  @vcunat suggested making this an arbitrary Nix expression rather than an attrpath, e.g. firefox.override { enableFoo = true; }. However, such an expression would not have a key in the user environment, unlike an attrpath. Better to require an explicit flag for this.

TBD: How to deal with search path clashes.
