Since last weekend I’ve been toying around implementing a calculator in Zig. One of my favorite algorithms I learned in college from my data structures classes were the shunting yard algorithm to parse and evaluate expressions, converting to the reverse Polish notation.

Today I decided to get some practice using Zig’s data structures from the standard library, building an old friend: a bc style calculator, implementing the algorithms to evaluate reverse Polish notation expressions and converting from infix to that notation.

In my Zig learning journey, I’ve managed to not use allocators for anything yet. I’ve watched this great video of Dude The Builder explaining the basics of allocators in Zig.

In the previous post, I went about my experiments with Zig and the FluidSynth Sequencer API.

Today I learned the basics of the FluidSynth Sequencer API. It is not super complicated, but it took me some time to understand the concepts, as not everything is explained in great detail.
