Do you mean

irb(main):003:0> words = "foo bar baz"
=> "foo bar baz"
irb(main):004:0> words.sub(/\w+/) {|m| "<b>#{m.upcase}</b>"}
=> "<b>FOO</b> bar baz"
irb(main):005:0> words.sub(/\w+/) {|m| "<b>#{m.capitalize}</b>"}
=> "<b>Foo</b> bar baz"
irb(main):006:0>

Kind regards

robert

Sure, that's a good way. A little-known feature of "split" is the
"limit" parameter, so you can split off just the first word without
affecting anything else:

arr = s.split(" ", 2)
arr[0].upcase! # and anything else you feel like
s = arr.join(" ")

Thanks for taking time to reply. much appreciated.

Is there any way, I can capitalize the string and simultaneously convert
the first word to bold.

right now, i am splitting

str.split(/\s+/).each{ |word| word.capitalize! } then upcase of str[0]
and then str.each{ |word| }.join(' ')
