Thanks for pointing that out, I think it was somewhere on my TODO list which miraculously got lost. I'll have a look at it!

Thanks!!

Thank you!

From the conceptual standpoint, it felt way clearer to me from the start. I knew I "just" had to parse some input text and figure out the instructions into which it should be turned into. The actual lexing and parsing of the source code text character by character lead me to way more errors and debugging sessions than I expected, but that's probably just me being a bit rusty.

So I would say the emulator was harder to grasp at first, as I had no prior lower level experience, had no idea what a register or a stack pointer or a program counter is, etc.

Thanks! Well at first I did not have much structure, I just went full procedural and did what I needed to do at each step. It was an ugly, long chain of loops and switches. Then I read up about assemblers a little bit, figured out what should go into the lexing/parsing/emitting stages and split it into classes.

The steepest part.. probably trying to do things efficiently, using string views instead of strings where relevant, references and also ranges + iterators in C++. The from_char function and how it reports errors (e.g. when the iterator it returns is the end of the provided range, there were no errors) etc.

Glad you noticed it! Indeed I tried to mix modern UI with retro style interfaces (like vim) with the hotkey bar at the bottom.
