Substrings and splitting
I have a lot of messages formatted like this
"42["message","base64:QWZ0ZXIgQnVuZGxlciBpbnN0YWxscyB0aGUgZ2VtcyBpbiB5b3VyIEdlbWZpbGUsIHlvdSBjYW4gcHJvY2VlZCB0byByZWZlcmVuY2UgdGhlbSBpbiA0eTQ0NG91ciBjb2RlIGp1c3QgYXMgaWYgeW914oCZZCBpbnN0YWxsZWQgdGhlbSB5b3Vyc2VsZi4="]"
What I want to do is if the message contains base64: then extract the substring after the colon and before the next quote mark.
edit: this works but is probably horrible.
if event.data.include? 'base64:'
new_string = event.data[event.data.rindex("base64:") + "base64:".length..-3]
puts new_string
end
ruby string
