String Module

All the functions in this module can be self-called on any string value, if that function expects a string as the first argument.

string.lowercase: vector<char>

An array of all lowercase letters.

string.uppercase: vector<char>

An array of all uppercase letters.

string.letters: vector<char>

An array of all alphabetic letters.

string.from(...): string

Joins all the arguments together into a string.

string.len(s: string): int

Returns the length of the s string.

string.iter(s: string): iterator<char>

Returns an iterator over the chars in the s string.

string.get(s: string, index: int, default: char?): char?

Returns the char at the index of the s string. Defaults to the default char if given.

string.sub(s: string, i: int, j: int?, default: string?): string?

Returns the sub-string of s from index i to j. If j is not given, it is the length of the string. If the indexes are out of range, default will be returned.

string.split(s: string, sep: string): vector<string>

Returns a vector of the string s split by sep.

string.split_amount(s: string, n: int, sep: string): vector<string>

Returns a vector of the string s split by sep, but only n amount of times.

string.split_at(s: string, idx: int): vector<string>

Returns a vector of the string s split at the index idx.

string.split_off(s: string, idx: int): string

Returns a the string s from index idx to the end of the string.

string.rep(s: string, n: int): string

Returns a repetition of the s string by n.

string.rev(s: string): string

Returns the reverse of s.

string.find(s: string, patt: string): string

Returns the starting position of the patt sub-string in s.

string.format(s: string, ...): string

Returns the formatted version of s with the rest of the arguments.

• %s: next argument as a string
• %q: next argument quoted if it is a string
• %x: next argument as a hexadecimal integer if it is a integer
• %%: just %

string.start(s: string, start: string): boolean

Returns true if the string s starts with the substring start.

string.end(s: string, end: string): boolean

Returns true if the string s ends with the substring end.

string.rmatch(s: string, pattern: string): string|vector<string>?

Returns the substring(s) in s that match the regex pattern pattern.
