At first, you need to split() the string on the basis of space and extract the first character using charAt(). Use toUpperCase() for the extracted character.
Ruby | String capitalize() Method capitalize is a String class method in Ruby which is used to return a copy of the given string by converting its first character uppercase and the remaining to lowercase.
To capitalize the first character of a string, We can use the charAt() to separate the first character and then use the toUpperCase() function to capitalize it.
This should do it:
title = "test test"
title[0] = title[0].capitalize
puts title # "Test test"
Titleize will capitalise every word. This line feels hefty, but will guarantee that the only letter changed is the first one.
new_string = string.slice(0,1).capitalize + string.slice(1..-1)
Update:
irb(main):001:0> string = "i'm from New York..."
=> "i'm from New York..."
irb(main):002:0> new_string = string.slice(0,1).capitalize + string.slice(1..-1)
=> "I'm from New York..."
You can use humanize. If you don't need underscores or other capitals in your text lines.
Input:
"i'm from New_York...".humanize
Output:
"I'm from new york..."
str = "this is a Test"
str.sub(/^./, &:upcase)
# => "This is a Test"
