Auto snippet matches alpha and \alpha #5

Closed mmiddlezong closed 4 months ago

Hey, just wanted to say I really appreciate this plugin. In math mode, typing alpha turns into \alpha and typing \alpha turns into \\alpha. Is this intended? I would expect typing \alpha to not trigger the snippet and return \alpha (unaffected). This issue is not noticed with \angle, for example.

Ah, this is because there's no regex pattern to prevent this snippet from triggering again when prefaced by a backslash. This should be a pretty quick fix; it should be updated now.

Thank you for the quick response and fix!

A similar issue exists with \sqrt, and I've implemented a similar fix in my fork of this repository but wanted to let you know.

Essentially the issue lies with snippets which have some trigger trig but produce something like \trig[optional stuff]; therefore I found a more efficient fix - just need to put a check that context.trig is contained within the command. This also eliminates the need for the backslash flag.
