I was adding a configuration option via -c or –config option, where it will accept a JSON file as config file to use the values inside instead of other options. It waseasy to plan for what and how I want to do, since it’s just about reading a file and using the variables. The hard part was figuring out how my code would be compatible with the repo I tried to add it to. I was working on this repo, and I opened an issue and filed a pull request. This static site generator tool doesn’t use any options but accept arguments directly, so I had to use minimist package to parse options. There are a few variables that aren’t listed in the config module, such as stylesheet url, so I added them and use the variables from the config module instead. I also ended up slightly rewriting the language option code so the program would actually use the code from the author. Overall, there where bits and pieces of code for other options that aren’t entirely functional as options, so I ended up rewriting them a bit for the configuration option to work.
