Thanks for sharing, I didn't know about TRex! I've been using TextSniper (https://textsniper.app) for this functionality -- not sure how these two compare, feature-wise.
And I didn't know about TextSniper. FWIW, TRex has only failed me less than 1 out of a hundred times, and only in edge cases like getting a crazy complicated URL from a tiny fuzzy web call. I also like that it's open source.
