CodeRunner <[https://coderunnerapp.com](https://coderunnerapp.com)> is a really useful utility app for Mac, a GUI scratchpad editor for writing and running code in dozens of languages, from Python and Bash to C/C++. It's not free or open-source, but IMHO it's well worth the $15. I use it a lot.
I put together a Nim plugin for it. Mostly I just needed to write a little shell-script to invoke the Nim compiler. The syntax-coloring library the app uses already supports Nim, but there's no syntax-aware indentation or autocomplete. Still, I find it really useful for trying out snippets as I learn the language. To install: * Download <[https://mooseyard.com/tools/Nim.crLanguage.zip](https://mooseyard.com/tools/Nim.crLanguage.zip)> * Unzip it * In CodeRunner's "Run" menu choose "Edit Languages..." * Pull down the gear menu at the bottom of the window and choose "Import..." * Select the "Nim.crLanguage" file from step 2 \--Jens| ---|---
