String

Built-in string class.

Description

This is the built-in string class (and the one used by GDScript). It supports Unicode and provides all necessary means for string handling. Strings are reference counted and use a copy-on-write approach, so passing them around is cheap in resources.

  • void erase ( int position, int chars )

Erases chars characters from the string starting from position.

Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index can be passed.

Finds the last occurrence of a substring. Returns the starting position of the substring or -1 if not found.

Finds the first occurrence of a substring, ignoring case. Returns the starting position of the substring or -1 if not found. Optionally, the initial search index can be passed.

  • int hex_to_int ( )

Converts a string containing a hexadecimal number into an integer. Hexadecimal strings are expected to be prefixed with “0x” otherwise 0 is returned.

print("0xff".hex_to_int()) # Print "255"

Escapes (encodes) a string to URL friendly format. Also referred to as ‘URL encode’.

Converts size represented as number of bytes to human-readable format using internationalized set of data size units, namely: B, KiB, MiB, GiB, TiB, PiB, EiB. Note that the next smallest unit is picked automatically to hold at most 1024 units.

var bytes = 133790307
var size = String.humanize_size(bytes)
print(size) # prints "127.5 MiB"

Returns a copy of the string with the substring what inserted at the given position.

  • bool is_abs_path ( )

If the string is a path to a file or directory, returns true if the path is absolute.

  • bool is_rel_path ( )

If the string is a path to a file or directory, returns true if the path is relative.

Returns true if this string is a subsequence of the given string.

Returns true if this string is a subsequence of the given string, without considering case.

  • bool is_valid_filename ( )

Returns true if this string is free from characters that aren’t allowed in file names, those being:

  • bool is_valid_float ( )

Returns true if this string contains a valid float.

  • bool is_valid_hex_number ( bool with_prefix=false )

Returns true if this string contains a valid hexadecimal number. If with_prefix is true, then a validity of the hexadecimal number is determined by 0x prefix, for instance: 0xDEADC0DE.

  • bool is_valid_html_color ( )

Returns true if this string contains a valid color in hexadecimal HTML notation. Other HTML notations such as named colors or hsl() colors aren’t considered valid by this method and will return false.

  • bool is_valid_identifier ( )

Returns true if this string is a valid identifier. A valid identifier may contain only letters, digits and underscores (_) and the first character may not be a digit.

  • bool is_valid_integer ( )

Returns true if this string contains a valid integer.

  • bool is_valid_ip_address ( )

Returns true if this string contains a valid IP address.

Returns a copy of the string with special characters escaped using the JSON standard.

Returns a number of characters from the left of the string.

  • int length ( )

Returns the string’s amount of characters.

Returns a copy of the string with characters removed from the left.

Does a simple case-sensitive expression match, where "*" matches zero or more arbitrary characters and "?" matches any single character except a period (".").

Does a simple case-insensitive expression match, where "*" matches zero or more arbitrary characters and "?" matches any single character except a period (".").

Returns the MD5 hash of the string as an array of bytes.

Returns the MD5 hash of the string as a string.

Performs a case-insensitive comparison to another string. Returns -1 if less than, +1 if greater than, or 0 if equal.

Returns the character code at position at.

Formats a number to have an exact number of digits after the decimal point.

Formats a number to have an exact number of digits before the decimal point.

Decode a percent-encoded string. See percent_encode.

Percent-encodes a string. Encodes parameters in a URL when sending a HTTP GET request (and bodies of form-urlencoded POST requests).

If the string is a path, this concatenates file at the end of the string as a subpath. E.g. "this/is".plus_file("path") == "this/is/path".

Returns original string repeated a number of times. The number of repetitions is given by the argument.

Replaces occurrences of a case-sensitive substring with the given one inside the string.

Replaces occurrences of a case-insensitive substring with the given one inside the string.

Performs a case-sensitive search for a substring, but starts from the end of the string instead of the beginning.

Performs a case-insensitive search for a substring, but starts from the end of the string instead of the beginning.

Returns the right side of the string from a given position.

Splits the string by a delimiter string and returns an array of the substrings, starting from right.

The splits in the returned array are sorted in the same order as the original string, from left to right.

If maxsplit is specified, it defines the number of splits to do from the right up to maxsplit. The default value of 0 means that all items are split, thus giving the same result as split.

Example:

var some_string = "One,Two,Three,Four"
var some_array = some_string.rsplit(",", true, 1)
print(some_array.size()) # Prints 2
print(some_array[0]) # Prints "Four"
print(some_array[1]) # Prints "Three,Two,One"

Returns a copy of the string with characters removed from the right.

Returns the SHA-1 hash of the string as an array of bytes.

Returns the SHA-1 hash of the string as a string.

Returns the SHA-256 hash of the string as an array of bytes.

Returns the SHA-256 hash of the string as a string.

Returns the similarity index of the text compared to this string. 1 means totally similar and 0 means totally dissimilar.

Splits the string by a delimiter string and returns an array of the substrings.

If maxsplit is specified, it defines the number of splits to do from the left up to maxsplit. The default value of 0 means that all items are split.

Example:

var some_string = "One,Two,Three,Four"
var some_array = some_string.split(",", true, 1)
print(some_array.size()) # Prints 2
print(some_array[0]) # Prints "One"
print(some_array[1]) # Prints "Two,Three,Four"

Splits the string in floats by using a delimiter string and returns an array of the substrings.

For example, "1,2.5,3" will return [1,2.5,3] if split by ",".

Returns a copy of the string stripped of any non-printable character (including tabulations, spaces and line breaks) at the beginning and the end. The optional arguments are used to toggle stripping on the left and right edges respectively.

Returns a copy of the string stripped of any escape character. These include all non-printable control characters of the first page of the ASCII table (< 32), such as tabulation (\t in C) and newline (\n and \r) characters, but not spaces.

Returns part of the string from the position from with length len. Argument len is optional and using -1 will return remaining characters from given position.

Converts the String (which is a character array) to PoolByteArray (which is an array of bytes). The conversion is faster compared to to_utf8, as this method assumes that all the characters in the String are ASCII characters.

Converts a string containing a decimal number into a float.

  • int to_int ( )

Converts a string containing an integer number into an int.

Returns the string converted to lowercase.

Returns the string converted to uppercase.

Converts the String (which is an array of characters) to PoolByteArray (which is an array of bytes). The conversion is a bit slower than to_ascii, but supports all UTF-8 characters. Therefore, you should prefer this function over to_ascii.

Removes a given string from the start if it starts with it or leaves the string unchanged.

Removes a given string from the end if it ends with it or leaves the string unchanged.

Returns a copy of the string with special characters escaped using the XML standard.

Returns a copy of the string with escaped characters replaced by their meanings according to the XML standard.
