We are approximately 3.5 months since lockdown started because of the COVID-19 pandemic, and the last time I blogged was mid November - which is incidently around when the first reported cases of COVID-19 started, so I’m not ruling out the possibility that it is somehow related, but I figure I write about some stuff I learned.
- I wrote a code interpreter! I wrote it in C# and basically ~copied~ learned from Lisperator. Nothing special, it only supported integers and floats and variables. I added support for negatives! wow! Seriously though, it was fun to write, and I learned about taking a complicated idea and breaking those down into smaller problems.
- I tried to write a powershell formatter. There is a fair bit of overlap with the above project. Lucky there is a built-in powershell parser that spits out both a series of tokens, and an AST. I started with the token approach, but moved to using ASTs. I started working on this because we write a lot of Powershell code at work, but we didn’t use any code formatter. It turned out that two formatters exist - PowerShell Beautifier and cleverly hidden inside the PSScriptAnalyzer is
Invoke-Formatter. The former has some issues though. - I grabbed an AKAI MidiMix and have been playing with it. My goal is to make some sort of poor-man’s reggae preamp - though a lot less cooler and much more limited. I’ve only really just started with it, and I have no idea what I’m doing.
I haven’t bothered putting any of these projects under source control as I never planned on releasing them. I think having throw-away projects provides a lot of value even if they never make it outside my machine.
