Calcutext – Do calculations with your written text
I was finally able to finish this open-source project that I built to about 90% completion nearly 2 years ago when my daughter was born, during my 1-month parental leave, and then sadly left untouched until a few weeks ago. Hope you enjoy trying out the app and looking at the source code! :) GitHub link here: https://github.com/jaredreich/calcutext
In plain words
Calcutext is an open-source tool that enables users to perform calculations directly within written text. Designed for developers and anyone working with text-based calculations, it allows math operations to be embedded seamlessly into documents or notes. The application is freely available with source code accessible on GitHub, making it suitable for users who want to integrate computational features into their writing workflow without switching between applications.

It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…

We're building Parsnip to create a "tech tree" of cooking skills that allows anyone to level up on the building blocks of cooking knowledge while tracking their progress over time.
