Came across this pretty nifty site HackAttic that provides a small set of practical oriented exercises. Will look at using further in my Go journey, as seems really useful to stretch one’s development skills in less familar, but still practical ways. A few of the challenges: Generate an SSL certificate according to given data. Extract some data from Redis. In a way. Handle some incoming JWTs for us. Take a look at the newsletter topics covered.

Generate diagrams as code using Python, if you prefer to have a bit more development oriented workflow for visualization.

progress initialized new start of cli tool to try to parse markdown content using Goldmark1 and then convert markdown links into reference style links Improved default template for starting new basic cli tools with Go to include zerolog and run based design instead of the majority of logic being in main. goldmark ↩︎

progress more taskflow work learned how to use io.Multiwriter to have both a stdout stream as well as output captured to a stringbuilder. got confused on reading docs, only to realize I was reading docs for a C# solution. 😂 used Pterm1 to beautiful console output, which was pretty cool to see in action. pterm/pterm: ✨ #PTerm is a modern go module to beautify console output ↩︎

progress Worked with Taskflow a bit more. Need to identify better error handling pattern on when to resolve vs handle internal to a function, as it feels like I’m doing needless error checking. Wrote func to run terraform init, plan, and apply. This takes dynamical inputs for vars and backend file. Also dynamically switches terraform versions by running tfswitch. Definitely more verbose code than powershell, but it’s a good way to get used to Go while achieving some useful automation tasks I need to do.

progress figured out how to import util/logger.go as a package after much confusion due to logger, log, *zerolog.Logger and more variables all deviously similar in name… how to pass around the initialized package logger that I configure. learned that global scope and package scoped loggers being initialized at run is concerned an anti-pattern properly wrapping to avoid the log initialization on import with type Logger struct { logger: *zerolog.Logger; } as an example avoids the same behavior as: var Log *zerolog.
