Today I got really annoyed at existing prettifier tools that I was using to reverse engineer a binary, so I built a little CLI tool that just prettifies files based on their file extension and/or headers, and which doesn't need runtime dependencies when installed as it's a standalone go binary. I wanted it to be as simple as possible, without any overengineered CLI flags that nobody will be able to remember.
Maybe this tool will be helpful to someone else, too.
