Perhaps someone could help with this example? I need to iterate
through each of the items in strings and wrap any case insensitive
occurrence of “key” with . If each string was always just the
word “key” I would use something like wrapper.join(“key”) but… I have
other text surrounding the “key”, various cases and potentially
multiple occurrences. Thank you in advance.
wrapper = ["", “ ”]
strings = [“blahblahKEY”, “asdfasdfkey”, “Keyasdf”, “xxkEYxx”,
“xxKeyxxKEY”]
strings.each do |string|
# would like to print the string replacing “key” (case
insensitive) with “key”(in its original case)
end
Ideally, would output:
“blahblahKEY ”
“asdfasdfkey ”
“Key asdf”
“xxkEY xx”
“xxKey xxKEY ”

wrapper = [“”, “ ”]
strings = [“blahblahKEY”, “asdfasdfkey”, “Keyasdf”, “xxkEYxx”,
“xxKeyxxKEY”]
strings.each do |string|
puts string.gsub(/key/i) {|match| “#{match} ”}
end
Maybe?
Hope this helps,

Hehe… Awesome!!!
Ok… one last thing… : key being a variable.
How would you knock this one out? Instead of the string “key”, lets
repace the occurance of the key variable, which in this case is “key”
but could be another string…
key = “key”
wrapper = ["", “ ”]
strings = [“blahblahKEY”, “asdfasdfkey”, “Keyasdf”, “xxkEYxx”,
“xxKeyxxKEY”]
strings.each do |string|
puts string.gsub(/key/i) {|match| “#{match} ”}
end

The simple, but incomplete/unsafe, approach might be:
thing = ‘key’
strings.each do |string|
puts string.gsub(/#{thing}/i) {|match| “#{match} ”}
end
If “thing” includes regex metacharacters then you might want to
consider looking at Regexp::escape and figuring out how it could help
those cases.
Hope this helps,
