Details

Description:

EssentialsX produces multiple errors when attempting to use the example regex in the Command Cooldowns documentation at https://github.com/EssentialsX/Essentials/wiki/Command-Cooldowns . Any similar regex also results in errors. I can't get any regex ending with ( .)? to work.

Steps to reproduce:

Enter the regex from the documentation for highly technical users, as shown in the above config file excerpt.

Expected behavior:

I expected that EssentialsX would work with the regex given in the official EssentialsX documentation. (It's almost like nobody ever tested this.)

This is the case for all regular expressions that have a period in them. This is pending an implementation of #3200.

My whole reason for going down the regex path was to have a unified cooldown for command aliases, which I see is being handled by #2058. So feel free to close this, or keep it open to keep track of the general regex bug and documentation.

Should be fixed in configurate when using quotes to encase the regex
