Monads and Friends...

Over the last 24-48 hours, I've fielded quite a flurry of tweets related to a couple of threads I posted recently. Upon reflection on the feedback, especially the negative stuff, I decided to write this blog post to clarify a few things about my background on the topic, what I was trying to say, what I've done so far, and what I'm hoping to do (and learn!) in the future.

It's a bit of a lengthy read, but if you find you've got the time, I hope you'll read it.

To be clear, the feedback has been on a broad spectrum. A lot of it was actually quite positive, people thanking me and appreciating my continued efforts to try to make dev topics approachable. As a matter of fact, over the years, I've received boat loads of such positive feedback, and I'm tremendously grateful that I've had a helpful impact on so many lives.

But some of it veered decidedly the other direction. I'm deliberately not linking to it, because I don't want to either amplify or gang up on those folks. I'm offended an

Switch To Vim For Good

NOTE: This guide has moved to https://github.com/bpierre/switch-to-vim-for-good

This guide is coming from an email I used to send to newcomers to Vim. It is not intended to be a complete guide, it is about how I switched myself.

My decision to switch to Vim has been made a long time ago. Coming from TextMate 1, I wanted to learn an editor that is Open Source (so I don’t lose my time learning a tool that can be killed), cross platform (so I can use it everywhere), and powerful enough (so I won’t regret TextMate). For these reasons, Vim has always been the editor I wanted to learn, but it took me several years before I did it in a way that works for me. I tried to switch progressively, using the Janus Vim distribution for a few months, then got back to using TextMate 2 for a time, waiting for the next attempt… here is what finally worked for me.
