Handle special TryAPL replies with backspaces

[rodrigogiraoserrao]

According to https://chat.stackexchange.com/transcript/message/58424796#58424796,
if TryAPL replies with a result that starts with a backspace, then it is a "special" reply that was tagged with the backspace so that the frontend of TryAPL could act in a special way. When that is the reply we get back, then the actual result we care about is the last item of the "backspace"-separated result.

It could raise the issue of "what if the expression typed actually returns a legit, purposeful backspace as the first character", but TryAPL returns the "picture" of the result, not the true result, so no legit result will ever start with backspace.

In fact, when you detect a help tag, simply respond with a tweet that has the returned URL. No need to say "Run it…" or include a picture.

Therefore, should I detect backspace-tags and then, if it is a help tag, special-case that as well?

[abrudz]

What do you mean by "as well"? There's only one thing to special case here:
If the result from the TryAPL request comes back with a text that begins with a backspace, remove the tag, and post the rest of the text as a tweet by it self, without the "Run it online" lede or adding a picture.

[rodrigogiraoserrao]

You are assuming, then, that the only results that will ever start with backspace are help results? Or is it a known fact that that is how it is going to work?

Good point. Better to check if the response begins with BShelpBS.
