Perl regex: horizontal space
Self-tutoring about Perl regular expressions: the tutor makes an observation.
Perl has the interesting character class \h that signifies “horizontal whitespace.” It can be very useful to capture a word in a sentence.
Suppose, for instance, you want to capture Hello76 from the following sentence:
On the brick wall old graffiti told this message: Jimmy Carter Hello76 Good Luck.
/\h\w*76/ should work:)Source:
