Rainix

Nix flake providing development environments and build tasks for the Rain Protocol ecosystem.

Rainix is shared infrastructure consumed by other Rain repos — the actual project code lives in downstream consumers.

Usage

Add Rainix as a flake input:

{
  inputs.rainix.url = "github:rainlanguage/rainix";
}

Dev Shells

Requires Nix with flakes enabled.

nix develop        # default shell (Solidity + Rust + Node + subgraph tools)
nix develop .#tauri-shell  # Tauri desktop app development

The default shell auto-sources .env if present and runs npm ci --ignore-scripts if package.json exists.

Build Tasks

All tasks are Nix packages run via nix run. From a consuming repo:

Solidity

• nix run ..#rainix-sol-prelude — forge install + build
• nix run ..#rainix-sol-test — forge test
• nix run ..#rainix-sol-static — slither + forge fmt check
• nix run ..#rainix-sol-legal — REUSE/DCL-1.0 license compliance
• nix run ..#rainix-sol-artifacts — deploy to testnet

Rust

• nix run ..#rainix-rs-prelude — environment prep (currently no-op)
• nix run ..#rainix-rs-test — cargo test
• nix run ..#rainix-rs-static — cargo fmt + clippy
• nix run ..#rainix-rs-artifacts — cargo build --release

Reusable Outputs

Downstream flakes can compose their own tasks and shells using:

• pkgs — nixpkgs with all overlays applied
• rust-toolchain — pinned Rust toolchain
• rust-build-inputs, sol-build-inputs, node-build-inputs — dependency lists
• mkTask — create Nix derivations wrapping shell scripts with dependencies on PATH
• network-list — supported network names

Pinned Versions

• Rust: 1.94.0
• Solidity: solc 0.8.25
• Foundry: via foundry.nix
• Graph CLI: 0.69.2
• Goldsky CLI: 8.6.6
