I'm trying to clean up some... 200 or so simple lazy-mans triggers, most of them aren't anchored, and are zscript not regex.

Anyway... I started to make a LUA alias to convert simple patterns from zscript to regex, it grew and got ugly, and now, well could a reference on the lua zs.trigger object, maybe .makeregex, that does the same thing as that nice lil green arrow next to the regex option for triggers?

Making your triggers into regexes doesn't do much, though. The first time the trigger's run, the zScript pattern is converted into a regex which is compiled. Converting your trigger will give you a very minor speed increase (the convert step is likely to pale in comparison to the compile step) for a lot of additional ballache. If you're not using a feature of regex that isn't emulated in zScript's patterns, you might as well leave them.

And actually, the RegEx triggers also get run through a "convert" step to deal with any variable references. So basically, zScript and RegEx triggers are exactly the same speed. RegEx is generally more complicated to understand and support later. So unless you are a real RegEx guru and prefer that syntax over the zScript syntax, or unless (as Fang says) you are doing something in RegEx that can't be done in zScript, you should really just stick with zScript. It will be easier for others to understand your scripts if you want to share them later.

Hmmm, I had considered that regex might be no faster than zscript patterns, was largely just a preference/consistency/additional options thing.
