what does \s* means?

[griffith Khana]

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






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

 

[Dasson, Raghav]

\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 wh=
enever 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:

http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_stdtypes.html

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