THIS GIST IS OUT OF DATE!  Please use my new project template here to get started with Zig on Playdate:
https://github.com/DanB91/Zig-Playdate-Template


The rest of this is preservied for historical reasons:


This is a small snippet of some code to get you started for developing for the Playdate on Zig.  This code should be used as a starting point and may not compile without some massaging.  This code has only been tested out on macOS and you'll need to modify the addSharedLibrary() portion of build.zig to output a .dll or .so instead of a .dylib, depending on you platform.

This code will help you produce both an executable for the Playdate simulator and also an executable that actually run on the Playdate hardware.

How to get in touch with your emotions

I wanted to share something I've learned in the course of therapy that I felt might benefit others. Specifically, I'd like to share how to better listen to one's emotions.

Why should we do this?

You might wonder why would we want to be in better touch with our emotions. One reason why is that everybody builds a metaphor or narrative for themselves

Portland recommendations by Sam

Sorted by location-ish. I tried to reduce the list to places I think are good for visitors vs. my absolute favorites, but I put a section at the bottom for places that may not be for everyone.

My order: Grilled mackerel breakfast with a bloody mary. Their Dalgona coffee is quite good too.

Invertible syntax descriptions

An "invertible syntax description" is something that can be used to both parse and generate a syntax. For example, instead of defining separate toJson and fromJson functions for a given data type, an invertible syntax description could be used to provide both. There are many Haskell libraries that provide this functionality or something close to it. As far as I can tell most of them are at least inspired by Invertible syntax descriptions by Tillmann Rendel and Klaus Ostermann.

Personally I am interested in using these for HTTP routing. I frequently want to be able to define a route such as /episodes/:id.json, dispatch based on that route, and generate links to that route. Doing so manually is tedious and error prone.
