Continuing on from Part 1 If you’ve not read that you probably should before continuing here. Previously we setup a pyo3 project and ran some python code from rust which was able to create a rust class and return it to rust. (I think I can say rust a few more times in this paragraph. Rust rust rust) This is the kind of python config we are aiming to be able to use inside our rust program:...
I’ve recently been playing with running python code from rust to use as a kind of configuration and extension system. The idea is that my program runs a bunch of python code that the user has defined and that gives it the configuration it needs. The user has the POWER OF THIS FULLY OPERATIONAL PROGRAMMING LANGUAGE cough cough, sorry voice box got stuck on imperial functionary there. I’m doing this as a personal project and proof of concept so don’t expect bullet proof code here....
For the last ${scairy_number_of_years} years I’ve been working on some library tooling to create SVG files using rust. There are some libraries that existed already but they either didn’t work for what I needed to do or they had limitations. So I build two libraries of my own. Polygonical and ESVG. Polygonical focuses on 2d geometry operations. Points, lines, polygons and doing things to them. It does not concern its self with how they are shown, what format they are written to disk or anything like that....
Today lets step through creating a new command line tool in rust. Recently I wanted to find one of my old toots, but it was from several months ago and mastodon doesn’t have the ability to search for anything other than usernames and hashtags. I couldn’t remember if I’d put hash tags in the post I was after so I couldn’t use the built in thing. What I did have however is my backup archive....
I have some code that creates pages of shapes. My wife uses this to create products for her etsy shop. I originally wrote this in java many years ago. Some time last year I decided to rewrite the entire thing in rust. There were a number of reasons for this. Mostly that I’d learned a heck of a lot since I designed the original architecture and wanted some features that would not be possible with out rewriting most of it any way....
