Literal Specific Methods

count(STRING)

Returns INTEGER

Counts how often a given substring occurs in the string.

🚀 > "test".count("t")
=> 2
🚀 > "test".count("f")
=> 0
🚀 > "test1".count("1")
=> 1

downcase()

Returns STRING

Returns the string with all uppercase letters replaced with lowercase counterparts.

🚀 > "TeST".downcase()
=> test

downcase!()

Returns NIL

Replaces all upcase characters with lowercase counterparts.

🚀 > a = "TeST"
=> TeST
🚀 > a.downcase!()
=> nil
🚀 > a
=> test

find(STRING)

Returns INTEGER

Returns the character index of a given string if found. Otherwise returns -1

🚀 > "test".find("e")
=> 1
🚀 > "test".find("f")
=> -1

format(STRING|INTEGER|FLOAT|BOOLEAN|ARRAY|HASH)

Returns STRING

Formats according to a format specifier and returns the resulting string

» "test1.50"
🚀 » "test%s".format("test")
» "testtest"

lines()

Returns ARRAY

🚀 > "test\ntest2".lines()
=> ["test", "test2"]

plz_i(INTEGER)

Returns INTEGER

Interprets the string as an integer with an optional given base. The default base is 10 and switched to 8 if the string starts with 0x.

🚀 > "1234".plz_i()
=> 1234

🚀 > "1234".plz_i(8)
=> 668

🚀 > "0x1234".plz_i(8)
=> 668

🚀 > "0x1234".plz_i()
=> 668

🚀 > "0x1234".plz_i(10)
=> 0

replace(STRING, STRING)

Returns STRING

Replaces the first string with the second string in the given string.

🚀 > "test".replace("t", "f")
=> "fesf"

reverse()

Returns STRING

size()

Returns INTEGER

Returns the amount of characters in the string.

🚀 > "test".size()
=> 4

split(STRING)

Returns ARRAY

Splits the string on a given seperator and returns all the chunks in an array. Default seperator is " "

🚀 > "a,b,c,d".split(",")
=> ["a", "b", "c", "d"]
