Having isues with capitalizing words

Ruby
1

So, this is a method I have made:

def title(words)
words.gsub(/(\A|\s)\w/) do |word|
if(word!=“and” || word!=“an” || word!=“the”)
word.upcase
else
word.downcase
end
end
end

I have been trying to solve this for the longest time and I can’t figure
it out.

All I want the method to do is take in a string and capitalize every
word except for “and” and “an” and “the”.

The above will not do it and I really don’t understand why. I have
tried a million versions of it as well.

Can someone help me get in the right direction with this?

Try using "and"s instead of "or"s.

Combine sagy’s and mine:

words.gsub!(/\w+/)do |match|
%w{and or a an the of}.includes?(match) ? match : match.capitalize
end

(or just use gsub without the ! if you want to work on a copy instead
of original)

Basically what sagy and tamouse said helped me solve this. Thanks for
the help
everyone :).

Your code wont work even after replacing or with ands:

Firstly, dont use || for or. Simply use or command.

Secondly, the capture group you defined (\A|\s) will catch only the
firstletter. Hence it will never be and , an or the. Maybe
just a or t.

This will work:

words.gsub!(/\w+/)do |match|

  • (match==“and” or match==“an” or match==“the”) ? match :
    match.capitalize

end

Enjoy
