dotenv .env files from imports are not added to config.env

[Maximilian-Staab]

Describe the bug

Using both devenv.yaml

imports: 
 - ./submodule

and submodule/devenv.nix

dotenv.enable = true;
services.minio.accessKey = config.env.VAR;

submodule/.env

VAR=123

breaks devenv shell.

To reproduce
This issue is related to the project structure, so I created a git repo instead of a gist. Here it is: https://github.com/Maximilian-Staab/devenv-env-loading-issue

Expextation

• Calling devenv shell with submodules that use dotenv.enable = true merges all applicable .env files.
• (maybe) Conflicting keys lead to errors if the values differ.
• I'm able to start all services/processes of all submodules from the root dir.

**Version**
 
Paste the output of `$ devenv version` here or tell us if you're using flakes.

[sandydoo]

This is expected. Paths and strings paths are resolved from the root of the project, ie. the top-level devenv.nix from where devenv shell is called. This is a Nix (and Nix flakes) limitation and we have absolutely no way resolving paths this way.

You can add additional paths with dotenv.filename = [ ".env" "submodule/.env" ];, but you'll have to stick to using the top-level devenv.nix.

[Maximilian-Staab]

Hi, thank you for your response.

I just tried this, but it seems like there's some string validation that breaks this. The error I'm getting is The dotenv filename must start with '.env'.

Here's the full log:
