Still working on the actual parser, but I did run into a situation where I actually needed to debug the parser in gdb. Not immediately obvious how to get this working, so I modified the myparser shell script with my...

I just finished the first programming assignment for the Stanford Compilers course, which was to implement a lexer for the Cool (classroom object oriented language) using Flex. Flex is a C-language based lexical analyzer generator. It generates a valid c source file for the lexical rules you put together. The .flex file format is basically a c file with some special syntax. The bulk of this assignment was hunting for implementation details. I do not enjoy courses as much when they don't go through an assignment...

Welp, still on the journey down to the hardware. Now that I've got the nand2tetris class on building a computer from nand gates out of the way, its time to dive into compilers. Update 2019: Looks like this coursera link is dead, I'm sure the course can be found though! I've decided to take Stanford's Coursera offering, though I've got a few reservations about it. First, it focuses quite a lot on formal definitions of languages and grammars. This means its using set notation and big unwieldy greek...

Course: http://nand2tetris.org/ My Computer (hdl): https://github.com/jmoyers/nand2tetris My Hack Assembler (rust): https://github.com/jmoyers/hack_assembler So I was able to build a baby computer in a hardware simulator. I learned quite a bit about how CPU's are designed and how they interact with machine code and assembly language. Finished this 6 week course in 5 days due to binge (🌙). I was able to write an assembler in about 500 lines of code including some static lookup tables. This assembler targets the...

If you are currently in a anti-IDE frame of mind (which I cycle into from time to time), tmux can be a useful way to use vim and also retain the ability to look at several pieces of output ... without a bunch of floating terminal windows hitting C-z and typing fg over and over. Current Setup I went through a period on intense tool customization, but I find it pretty hard to pick back up on all the little customizations if I walk away from a toolset for a while. I've since been wary of keeping too many dotfiles....
