Language agnostic code generator in Pen.el

Summary

Following on from YASnippet combined with Pen.el - Controllable prompt generation // Bodacious Blog, I make another language-agnostic code generator.

Behind the scenes, this prompt generates the comments describing a code snippet. The comments are in the desired language and the comments are removed from the results.

Unfortunately, I ran out of credits, but I don’t think it worked too well anyway.
