Show HN: Geomatic – a command-driven geometry studio enabled with autodiff

I liked this one, but it took me a while to understand, I think this page is a much better intro:

reply- When I have an example open, I can't type any commands.
reply- When I open an example, I expected to actually... see an example. I'm not gonna read the wall of text. I don't even understand what this is yet, that's why I tried to see an example.

Click "Draw a single n-star"
Results in a message popping up "unknown command: n-star"
replyYou have to load the extension, the instructions are in the text above the button.

replyClean implementation. One thing I always look for: how does this degrade when things go wrong? Good error handling is what separates weekend projects from tools people actually use.
replyAs an adult, I now write clean error handling first thing.
replyThe person it benefits the most is the author, when they are building it and the errors-per-use are as high as they’ll (hopefully) ever be.
Pretty cool. Curious, why a one time payment? Why not, say, a smaller monthly payment?
replyNot OP, but for me personally I’m tired of subscriptions. I’m grabbing the one time payment before OP changes his mind.
replyNot a fan of subscription hell myself, I plan to use one-time payment for all my products. Implementation wise one time payment is much simpler than setting up smaller payments that cap at a fixed amount.
replyCool idea but not very mobile friendly it seems.
replyWhat is autodiff?
replyAutomatic differentiation. For any DAG with a scalar output, it allows calculating its partial derivative wrt the input parameters.
replyI don't understand what the use automatic differentiation for in this context.
