PREMISE
This contains various regexes that I find useful.
Match any character except newline
.
Match particular first word of a string on a multiple lines
/(word1|word2|word3)/igm
Match multiple lines of negative and positive floating point numbers with a value less than 1000.
/^-?\d{1,3}\.\d+$/igm
Do not return result from a group
(?:)
For example, do not return the year from this string:
12/06/2016 05:52
(^\d{2}/\d{2}/(?:2015|2016) (\d{2}:\d{2})$)
You'll note that everything else is being captured, as well as the time being caputured by a specific group. However, this will not include 2015 or 2016.
