The language options are very well hidden on Yep. To get it, we have to do the following:
|
|
- Load the yep.com mainpage and extract the URL of the JavaScript app
|
|
- Load the JavaScript source code and extract the URL of all imported modules from it
|
|
- Load the imported modules to search for the right one that contains the languages
