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.

• String sha256_text ( )

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

• String strip_edges ( bool left=True, bool right=True )

Returns a copy of the string stripped of any non-printable character at the beginning and the end. The optional arguments are used to toggle stripping on the left and right edges respectively.

• String substr ( int from, int len )

Returns part of the string from the position from with length len.

• PoolByteArray to_ascii ( )

Converts the String (which is a character array) to PoolByteArray (which is an array of bytes). The conversion is sped up in comparison to to_utf8() with the assumption that all the characters the String contains are only ASCII characters.

• float to_float ( )

Converts a string containing a decimal number into a float.

• int to_int ( )

Converts a string containing an integer number into an int.

• String to_lower ( )

Returns the string converted to lowercase.

• String to_upper ( )

Returns the string converted to uppercase.

• PoolByteArray to_utf8 ( )

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().

• String trim_prefix ( String prefix )

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

• String trim_suffix ( String suffix )

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

• String xml_escape ( )

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

• String xml_unescape ( )

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