What does \s* means?

what does the .\s* means in the following commad

class String
def sentences
gsub(/\n|\r/, ’ ').split(/.\s*/)
end
end

\s* means occurrence of zero or more white spaces.

gsub(/\n|\r/, ’ ').split(/.\s*/) is basically first removing all the
line feeds and carriage returns and then the sentence is split into an
array whenever a dot followed by zero or more white spaces is
encounterd.

it’s actually ‘.\s*’ => match a ‘.’ followed by zero or more spaces

read the regular-expression section for more details:

class String
def sentences
gsub(/\n|\r/, ’ ').split(/.\s*/)
end
end
