Grep style for bolding through a second m-dash

Hi @MyrtleTree, here is one that captures up until the 2nd em-dash.

^([^~_\r]*~_){1,2}

However, I wouldn't suggest putting that in a grep style because in my experience there are often exceptions which make things awkward later on. So when I set up a grep style like this I actually use the grep (like Brian's or mine above) to do a search and replace to add a special marker character at the end of the found em-dash. It should be a zero-width character, eg. a non-joiner or a zero-width-space. The replacement (using a non-joiner ~j) would be:

$0~j

Then I set up the grep style like this:

^[^~j]*~j

 which will capture everything up until the first non-joiner character. See screen shot, showing invisibles:

The reason I do this is (a) initially it gives the same result as a straight grep style, but (b) when an exception occurs, you can just manually move the non-joiner character to where you want it. (Note: to select zero-width characters you need to use the left or right arrow-keys with shift.)

Try the attached demo file if it helps.
