matching triggers with _

I have an external input that generates a trigger with an underscore in it, like qrscene_visademo

I’m trying to understand how this can be matched or gets converted inside rive. Rive cannot accept punctuation in triggers, correct? But I thought it would strip out all the _ from any inputs too?

So then how should I write a trigger?

qrscene_visademo -> qrscenevisademo

neither of these seem to match.

in debugging the triggers I see this:

Try to match "scene qrscene_visademo" against scene qrscene_visademo (scene qrscene([A-Za-z]+?)visademo)

So I’m not really sure what that expansion is? It looks like the regex code but … qrscene([A-Za-z]+?)visademo would remove any such _ commands?

I’m also going to experiment with this:

bot.unicodePunctuation = new RegExp(/[.,!?;:]/g);

which could maybe leave the incoming message untouched?

Originally I used \w+ for that wildcard (which would likely also catch Unicode symbols), but \w also matches numbers which I wanted to avoid, so I changed it to [A-Za-z]+, but that only matches ASCII letters.

Maybe it would be better to make it match [^0-9]+ to instead exclude numbers rather than try to include all Unicode symbols.

👍 @kirsle 1 vote for excluding numbers and spaces. The expression [^\s\d]+ would be better for my unicode language. Thank you !
