split() but keep delimiter
perl, split
Solution
You can use lookbehind to do this:
split(/(?<=\.)/, $string)
The regex matches an empty string that follows a period.
If you want to remove the whitespace between the sentences at the same time, you can change it to:
split(/(?<=\.)\s*/, $string)
Positive and negative lookbehind is explained here
Problem
``` my $string1 = "Hi. My name is Vlad. It is snowy outside."; my @array = split('.' $string1); ##essentially I want this, but I want the period to be kept ``` I want to split this string at the `.`, but I want to keep the period. How can this be accomplished?
