Allow dotenv macro to provide a default value #67

Closed Vrixyz closed 1 year ago

Vrixyz commented 1 year ago

My use case is:

when building for production, I want my environment to be embedded in the binary (I'm building on wasm)
- dotenv!("env_key") fits my needs 🎉
when building on development, I'd like to be able to pass a default value (which could be a runtime value, such as an enviroment variable)
- dotenv!("env_key") fails the compilation 👎

This PR adds a try_dotenv!("env_key", "default value") which does not create a compilation error if the second parameter is correct.

Vrixyz commented 1 year ago

actually, dotenv! already does that, but I need to create a .env file to bypass compilation, I'm closing this as the workaround to create a ".env" is good enough for me.
