Domain Specific Language for knitting patterns
Grid-based editors are handy for colorwork. Knitspeak is great for lace. Knotty aims for the best of both worlds. It's a way to design knitting patterns that incorporate both textured stitches and multiple colors of yarn.
Knotty patterns are encoded in a format that is easy for humans to write and parse, but is also highly structured.
Patterns can be viewed and saved in an HTML format that contains an interactive knitting chart and written instructions. You can also import and export Knitspeak files, and create Fair Isle patterns directly from color graphics.
Knotty has been coded as a module for Typed Racket. Reference information is available in the manual.
A Knotty executable is also available that can be used from the command line to convert knitting patterns from one format to another.
