Refactor and test

[spejman]

A proposal to refactor the code in different files split per functionality:

• src/logger.js -> everything related to logging.
• src/cli.js -> parse input, printing help, managing args.
• src/pages.js -> modifying and converting pages content.
• src/filesystem.js -> dealing with the files and directories.

Also added two files with a small set of tests that ensures the script behaves as expected, and also speeds up the development because you can easily add a test with the bug that is failing and run the tests after each code change to ensure it's fixed.

@spejman Wow! This is incredible. Thank you so much for all of the work you've put into this! The reason I hadn't split it up originally (and why I stopped working on the TypeScript branch) is because I wanted to make using the script very accessible with a single curl. It's definitely gained more usage than I ever expected so I guess it would be best to create an NPM package. The testing suite has become a necessity so I can't thank you enough for that as well.

I'll review this in-depth tonight and likely complete the pull request then.

@spejman I'm having issues getting this to run - startConversion in main.js is not defined, fs in cli.js is not defined, regex[1] is failing in pages.js.

I think this is a good idea, but it's going to need some work before it can be merged. I'll take a closer look as soon as I can but I'll be really busy for a while so I can't make any guarantees to my timeline.

Thank you!

Hi @connertennery ! Sorry I didn't have the notifications properly configured and didn't get the notification of your comments.

I just checked your comments and noticed that my last merge 'main' broke the code, I just fixed it, it should work as expected now.

I also just used decodeURI like a1a76db (Note that I didn't use decodeURI on image URLs because otherwise images are not automatically shown in Obsidian).

Thanks!
