direnv on Windows

Overview

In JavaScript projects, I used to use dotenv so that I could put local environment variables in a .env file for local development. But dotenv requires you to add code to your project. With direnv, you can put local env vars in a .envrc file and those env vars are loaded automatically in the shell.

Steps to install

For these steps, it is assummed that you have installed Git Bash on Windows. I also use VSCode as my editor.

1. Create a folder such as c:\tools to put the direnv.exe file and add it to the Windows PATH

Overview

Using this you can run against a directory that has nested files/folders with files of *.avro.

This will walk the tree, convert alongside each of the avro files.
