Improving the reference date parsing from a title when using `tp.date.now()`/`moment()` ? 🤔 about templater HOT 4 OPEN

Hi @I-Pch, hi @Zachatoo,

Thank you very much for this detailed issue description. I can here for a likely related problem. I want to check if the filename is already in a "YYYY-MM-DD" format. If it is, nothing should be changed but if not I want to trigger a selection promt to choose from a couple of options. I'm now using a try/catch statement together with tp.date.now (which throws an error if parsing with the given format fails). Unfortunately there isn't any error for a filename with a number in it and I need to check the year (I added a check if the year is below 2000 it's an invalid date). I tried to use moment with strict mode but as mentioned in the discord conversation templater checks the date itself and shows an error message (and stops the script processing).

Is there any workaround I could use to check the file title according a given date format? I think I will use a regular expression check by now to handle my use case.

@IchHabRecht You can use moment directly like this:

<%*
if (!moment(tp.file.title, "YYYY-MM-DD", true).isValid()) {
  // do something if filename isn't in YYYY-MM-DD format
}
-%>

Hi @Zachatoo

Thanks for answering so quickly. Unfortunate it seems I don't get a moment object for invalid titles in strict mode. Templater seems to catch that case internally. An error message is shown and the script seems to be stopped.

@IchHabRecht What's your full template? Or a minimum reproducible example? The example I provided seems to be working for me.
