This commit adds a new parser for YT's shelfRenderers which are
typically used to denote different categories.The code for featured
channels parsing has also been moved to use the new parser but some
additional refactoring are needed there.
The ContinuationExtractor has also been improved and is now capable of
extraction continuation data that is packaged under
"appendContinuationItemsAction"
In additional this commit adds some useful helper functions to extract
the current selected tab the continuation token. This is to mainly
reduce code size and repetition.
This commit completely rewrites the extract_item and extract_items
function. Before this commit these two function were an unreadable
mess. The extract_item function was a lengthy if-elsif chain
while the extract_items function contained an incomprehensible
mess of .try, else and ||.
With this commit both of these functions have been pulled into a
separate file with the internal logic being moved to a few classes.
This significantly reduces the size of these two methods, enhances
readability and makes adding new extraction/parse rules much simpler.
See diff for details.
This commit changes the way search filters are parsed. Instead of
directly appending the data into the search query and creating k:v
pairs, all of the search filters are now a URL parameter. This results
in a clear look overall and hides much of the logic from the end user.
Closes#1969
