Nix overlay for gakonst/foundry (including forge and cast)
This repository is auto-updated daily with the latest nightly binary release.
If we have nix v2.4 or newer, we run this repo and get forge is the default app target:
$ nix run github:shazow/foundry.nix
forge 0.1.0 (691c814 2022-02-11T00:23:35.582887615+00:00)
Build, test, fuzz, formally verify, debug & deploy solidity contracts.
...We can also specify a target, such as cast:
$ nix run github:shazow/foundry.nix#castFlags are passed after the command is terminated with --:
$ nix run github:shazow/foundry.nix#forge -- buildWe can enter a shell with all of the foundry binaries injected:
$ nix develop github:shazow/foundry.nixMake a flake.nix in your solidity project directory:
# flake.nix
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
utils.url = "github:numtide/flake-utils";
foundry.url = "github:shazow/foundry.nix";
};
outputs = { self, nixpkgs, utils, foundry }:
utils.lib.eachDefaultSystem (system:
let
pkgs = import nixpkgs {
inherit system;
overlays = [ foundry.overlay ];
};
in {
devShell = with pkgs; mkShell {
buildInputs = [
# From the foundry overlay
# Note: Can also be referenced without overlaying as: foundry.defaultPackage.${system}
foundry-bin
# ... any other dependencies we need
solc
];
# Decorative prompt override so we know when we're in a dev shell
shellHook = ''
export PS1="\e[1;33m\][dev]\e[1;34m\] \w $ \e[0m\]"
'';
};
});
}Then run nix develop to enter a shell with foundry binaries (forge and cast) present.
Running nix flake update will repin to the latest foundry release from this repo (auto-updates daily).
The foundry forge and cast binaries are auto-ELF-patched to work on NixOS, but by default forge will attempt to fetch solc binaries which are not patched. To avoid this, --no-auto-detect must be used with a locally-installed solc. See: foundry#545
