Exclusion Environment

[LynetteCullens]

How do I exclude fractions from \pu environment?[ ["^{", "}"], ["\\pu{", "}"], ["\pu{", "}"] ]
That didn't work. Also, [ ["^{", "}"], ["\\pu{", "}"] ] didn't work.
Another question is how do I prevent \pu from outputting when I'm trying to type \pu? I know how to remove the snippet from the default settings, but am I using the plugin incorrectly?

How do I exclude fractions from \pu environment?

This is already done by default; here is the default setting for reference:

[
	["^{", "}"],
	["\\pu{", "}"]
]

Another question is how do I prevent \pu from outputting when I'm trying to type \pu? I know how to remove the snippet from the default settings, but am I using the plugin incorrectly?

Yes, simply remove the snippet in the plugin settings. You can customise any/all of the snippets to your liking; there's no "incorrect" way to use the plugin!

My current Excluded environments have been reset to default.
[ ["^{", "}"], ["\\pu{", "}"] ]
Also, I have been using the plugin incorrectly by typing "\pu" instead of just "pu", I kept getting "\pu".

Edit: I've figured it out thank you. I didn't realize there was also an autocomplete fraction function inside the default snippet file that went along with the auto-fraction toggle function.
I've just edited it to read:
{trigger: "//", replacement: "\\frac{$0}{$1}$2", options: "m"},
