Searching in Strings

The in operator tells you whether a text appears in a string. When you need more than yes or no, strings have search methods:

• contains(text) returns true if the text appears anywhere, like in
• begins_with(text) and ends_with(text) check only the start or the end
• find(text) returns the index where the text first appears, or -1 if it does not appear
• rfind(text) returns the index of the last appearance
• count(text) returns how many times the text appears

var email := "alice@coddy.tech"
print(email.begins_with("alice"))
print(email.ends_with(".tech"))
print(email.find("@"))
print(email.find("x"))
print(email.count("c"))

find() takes an optional second argument: the index where the search starts. Use it to find the next appearance after one you already found:

var text := "one fish, two fish"
var first := text.find("fish")
print(first)
print(text.find("fish", first + 1))

These methods are case-sensitive: "Hello".contains("hello") is false. Convert the string with to_lower() first, or use the versions that ignore case: findn(), containsn() and countn().
