Direnv Integration

Rensa provides a custom direnv integration to make your development experience smoother. It allows you to automatically load development shells defined in your cells.

Note

This integration is based on nix-direnv but has been improved and optimized specifically for Rensa usage.

Setup

1. Create .envrc: Add the following to your .envrc file:

   source $(fetchurl https://gitlab.com/rensa-nix/direnv/-/raw/v0.3.0/direnvrc "sha256-u7+KEz684NnIZ+Vh5x5qLrt8rKdnUNexewBoeTcEVHQ=")
   use ren //backend/devShells/default
   

   This will automatically load the devShell default defined in cells/backend/devShells.nix.

2. Allow Direnv: Run direnv allow to trust the configuration.

Updating

To update the direnvrc to the latest version (or a specific version), you can use direnv fetchurl.

1. Run fetchurl:

   direnv fetchurl https://gitlab.com/rensa-nix/direnv/-/raw/v0.3.0/direnvrc
   

   Note: Replace v0.3.0 with the desired version tag.

2. Update .envrc: The command above will output a new hash. Replace the previous version and hash in your .envrc with the new values.
