Develop

The om develop command should be used indirectly in direnv, via the use omnix directive in your .envrc.

Getting started

1. Put this in your .envrc file:

   source_url https://raw.githubusercontent.com/juspay/omnix/75ed48923835963e2f18baba08f54a8adc307ba2/omnixrc "sha256-8C2Jb5bHx/0cvm1+9gOlBEdWzbikCWT5UsJWewUAFt4="
   watch_file om.yaml
   use omnix
   

2. You should also create an empty (or fleshed out) om.yaml file in your project to avoid Nix evaluation:

   touch om.yaml
   

What does it do?

use omnix wraps use flake (of nix-direnv) providing additional capabilities:

• Run om health to check the health of the Nix environment.
  • Run cachix use automatically if the project uses cachix.
• Print a welcome text after spawning the Nix devshell.

The ideal goal here being that cd’ing to a project should do everything necessary to get you started immediately.

Welcome text

The welcome text can be configured in your om.yaml file. For example:

develop:
  default:
    readme: |
      🍾 Welcome to the **omnix** project

      To run omnix,

      ```sh-session
      just watch <args>
      ```

      (Now, as you edit the Rust sources, the above will reload!)
