Diff and populate your .env file from .env.dist automatically.

Usage

If you have a .env.dist file committed in GIT and after a recent git pull it has been changed, so now you need to add those new env-variables to your own .env.
This should be as easy as running envpopulate.

Upon running it, you will be asked if you want to enter custom values for every variable that doesn't yet exist in .env, if you don't want any interactivity then you need to include --quiet option.

Building

This utility is written in Rust so that you could get a small binary executable that doesn't require any additional dependencies like an interpreter or a VM and it could be easily bundled in a docker container.

Here's how you can get an executable in order from simplest to hardest:

• download already-built binaries from the latest release, this includes: Linux builds for various architectures, OS X builds for x86_64 and i686, and a Windows GNU build
• using Docker run in directory containing your .env.dist file: docker run --rm -ti -v "$PWD":/usr/src/env -w /usr/src/env nikita2206/envpopulate:latest
• install using Cargo: cargo install envpopulate
• checkout this repo using GIT and build with cargo build
