Replit Nix Modules

This repository holds Replit's Nix modules.

• Each module is located as a folder under pkgs/modules
• pkgs/modules/default.nix specifies a list of the active modules, some of which are parameterized with the version of the runtime or compiler

To list all active modules, you can do:

nix eval .#activeModules --json | jq

Output might look like:

{
  "bun-0.5": "/nix/store/l08f5vl1af9rpzd7kvr0l5gx9v7y8p12-replit-module-bun-0.5",
  "c-clang14.0": "/nix/store/n4vzd9rkpjs72xj9yvlakxh3bardvdki-replit-module-c-clang14.0",
  "clojure-1.11": "/nix/store/giqq76fl3yphzsm6rkl1qxqh4mszknpl-replit-module-clojure-1.11",
  "cpp-clang14": "/nix/store/8iv4czda6j5nfhxs80ci625hj91ffpbn-replit-module-cpp-clang14",
  "dart-2.18": "/nix/store/mhl58f8y3z6jv0javkmx28y5h9aacw39-replit-module-dart-2.18",
  "dotnet-7.0": "/nix/store/06mjna44a7w9bby6r121a7i9a5027qqn-replit-module-dotnet-7.0",
  "go-1.19": "/nix/store/y1gb1k8bkyd9jqxi4r1g9qibcqn3c6dm-replit-module-go-1.19",
  ...
}

To list all modules (including historical modules):

nix eval .#modules --json | jq

This will take a while.

Building

For each of the following examples, the build result will found be in a file or directory named result.

To build all active modules (this will take a while, and a lot of disk space):

nix build .#bundle

To build only a few modules which you can control by editing the dev-module-ids list in pkgs/default.nix:

nix build .#custom-bundle

To build a specific module, for example python-3.10, you can do:

nix build .#'"python-3.10"'

To build a disk with only a few modules for development purposes:

nix build .#bundle-squashfs

or

nix build .#custom-bundle-squashfs
