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.

Generate Jar with dependencies (fatJar) using Gradle

There are multiple posts (old and new) with instructions on how to generate a fat jar, this is, a jar file for your application containing also your application's dependencies. Most solutions I have tried did not work for me, even in a simple Hello World java application, but I have found one that seems to work as expected.

Here it is:

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1
