Automatic Asset Validation

When you have many various assets, some basic sanity checks go a long way!

I was already verifying the existence of assets based on the stream type, but with a script automatically uploading my markers, I needed to have some checks on that data!

Markers

The simplest to check would be Started & Ended markers not matching up - it's the classes are-the-parentheiss balanaced problem, but with partly dynamic substrings instead of individual characters! Next was ensuring these Started/Ended markers were correctly cased - capitalized first letters - and then ensuring there were no blank lines in markers file at all.

Slide-Matching

The most useful validation was ensuring the text for slide-markers actually existed in the slide text, of course I needed to download & parse the slides text first, but this turned out to be only a few lines after discovering the query needed to get the current slide and using jsdom to parse it.

Not only did this help me discover many of markers being off-by-one, but also eliminated the time I'd manually spend checking the markers!

Chat

Then I decided to ensure that the download chat matched the stream - date was the same, there were no markers after the last chat message, etc.

This did actually catch a few chat.jsons in the wrong folders!


There's little more that could usefully be validated, though I had add a remaining-days-counter to classes without YouTube reuploads, to ensure I continally check for those uploads.
