Summary

Would be super to have a button to create simple machine translations of text using DeepL's service

DeepL

DeepL has a paid API, but this could potentially just use their regular web page, called via javascript. They throttle excessive calls, so calls would need to be timed/throttled/limited.

Outline, possible solution

Add js methods with tape tests:

• makeChunks(srctext, maxsize=5000): take paragraphs from srctext, and join them into chunks of maxsize, breaking on paragraphs. Returns array of paras, eg "a \n b \n c" => [ "a \n b", "c" ] for maxsize 2. Could potentiallyyield results.
• getSingleTranslation(txt, srclang, destlang): call DeepL web page with some text, scrape the result, and return the text. src and dest langs are the deepL available languages.
• getTranslation(txt, srclang, destlang, updateCallback): main method, breaks txt into chunks and translates each. Needs to throttle the calls to getSingleTranslation, perhaps limit them. updateCallback is to update some UI or console, to track progress.

If we need to use a node library, that should be ok, Parcel should hopefully be able to bundle things correctly.

Add UI:

• not sure of design -- maybe a button on the main page above the text box, which lets you deepl translate from the other text box
• when click button, add a "translating ... " div, perhaps showing the start of the current chunk being translated, and a progress meter. Translating ... 90% done ("Cuando era niño, mi madre siempre me decía ..."), and append the data to the destination box
• add notes about auto translation to menu, warning about throttling and how to deal with it
