ql-to-nix-shell

This is a skeleton for a Common Lisp project.

The goal is to reuse the facilities provided by nixpkgs to generate expressions for quicklisp packages.

Usage

1. Enter required systems line by line in ql.txt.
2. Run nix-shell:
   • If no expressions have been generated before:
     1. ql-to-nix.lisp and top-package.emb, the sources for which are distributed with nixpkgs, are patched and installed
     2. quicklisp-to-nix is called inside ./nix-lisp with arguments --local (provided by patching) and . for current directory
     3. nix-shell exits
   • If expressions have been generated:
     1. ./nix-lisp/lisp.nix is imported
     2. Packages in ql.txt are used to create inputs for your shell
     3. A wrapper lisp is provided to load linedit when it is installed

Note:

• Overrides in ./nix-lisp/quicklisp-to-nix-overrides.nix are to be written manually.
• Provided .envrc uses lorri

What is patched in quickisp-to-nix

1. quicklisp-to-nix when called locally should check if requested quicklisp package already exists in the nixpkgs tree, that is why we patch ql-to-nix.lisp
2. top-package.emb is the template for final quicklisp-to-nix.nix and it uses a relative path to the nixpkgs tree to load define-package.nix, which makes it unusable in a local shell. Instead, we pass buildLispPackage as an argument
