string
The string module contains functions that primarily work with strings.
Functions
bytes(input)
Returns the number of bytes composing the input string (may not be equivalent to the number of codepoints!).
Returns an integer
capitalize(input)
Turns the first character in the input string to upper case. This does not ignore leading non letters!
Returns a string
contains(input, string)
Returns if the input string contains another string or not.
Returns a bool
format(format)
The placeholder {} is replaced by the arguments in the list in order.
string::format("the {} is {}.", "meaning of life", 42)
would result in the string
"the meaning of life is 42"
To use { or } as string literals in your format string, it needs to be
escapedby adding another parenthesis of the same type.
string::format("{{ this is a string format in parenthesis }}")
this will output:
"{ this is a string format in parenthesis }"
Returns a string
from_utf8_lossy(bytes)
Turns a binary into a utf8 string, potentally discarding invalid codepoints
Returns a string
into_binary(bytes)
Turns a string into it's binary representation
Returns a binary
is_empty(input)
Returns if the input string is empty or not.
Returns a bool
len(input)
Returns the length of the input string (counted as utf8 codepoints, not bytes!).
Returns an integer
lowercase(input)
Turns all characters in the input string to lower case, based on the Unicode Lowercase property.
Returns a string
replace(input, from, to)
Replaces all occurrences of from in Input to to.
Returns a string
reverse(input)
Reverses a string
Returns a string
split(input, separator)
Splits the input string at every occurrence of the separator string and turns the result in an array.
Returns a string
substr(input, start, end)
Get all codepoints from index start to end-1.
Returns a string
trim(input)
Trims whitespaces both at the start and end of the input string. All codepoints with the unicode property White_Space are considered whitespace here.
Returns a string
trim_end(input)
Trims whitespaces at the end of the input string. All codepoints with the unicode property White_Space are considered whitespace here.
Returns a string
trim_start(input)
Trims whitespaces at the start of the input string. All codepoints with the unicode property White_Space are considered whitespace here.
Returns a string
uppercase(input)
Turns all characters in the input string to upper case, based on the Unicode Uppercase property
