I want a regex that can find all $gme or gme. It should not find $gme or gme in a string like
hello $gmee
or
hello g$gme
So for example in a string such as
Hello gme. Hey $gme. Hey $gmee. Hey gmee.
It should find only gme or $gme from the above string.
It must also find gme or $gme when there is no space before or after a string For example
$gme
or
gme
I am writing a script that can count the number of times $gme or gme is mentioned in a string
So in a string like
Hello gme. Hey $gme. Hey $gmee. Hey gmee.
Its mentioned only two times.
I hope its clear now.
Regex I have tried
\$gme$|\sgme\s|\sgme|^gme\S
The above one fails when there is no space before and after $gme or gme. And also it includes gmee and $gmee which I don't want to include.
You can use use a mix of whitespace and word boundaries:
(?<!\S)\$?gme\b
See the regex demo
Details:
(?<!\S) - a negative lookbehind that fails the match if there is no non-whitespace char immediately to the left of the current position (so, start of string or a whitespace must occur immediately on the left)\$? - an optional $ chargme - a word\b - a word bounary.Collected from the Internet
