string

The string module implements string utility functions.

Functions#

to_int(string)#

Converts the given string to a signed integer. If the string starts with “0x” it is treated as base 16. If the string starts with “0” it is treated base 8. Leading ‘+’ or ‘-’ is also supported.

Examples:

string.to_int("1234") == 1234

string.to_int("-10") == -10

string.to_int("-010") == -8

to_int(string, base)#

Converts the given string, interpreted with the given base, to a signed integer. Base must be 0 or between 2 and 36 inclusive. If it is zero then the string will be interpreted as base 16 if it starts with “0x” or as base 8 if it starts with “0”. Leading ‘+’ or ‘-’ is also supported.

Examples:

string.to_int("011", 8) == 9

string.to_int("-011", 0) == -9

length(string)#

Returns the length of the string, which can be any sequence of bytes. NULL bytes included.

Examples:

string.length("AXSx00ERS") == 7
