makevalidvarname

Since	19.5

string  makevalidvarname(string name)

string  makevalidvarname(string name, string safe_chars)

Variable names in languages such as VEX are only allowed to contain letters, numbers, and underscores, and must not begin with a number. Node names and attribute names in Houdini have similar requirements. This function takes any string, and converts it into a string that obeys these restrictions by replacing invalid characters with an underscore.

name

String that should be turned into a valid variable name.

safe_chars

String specifying any extra characters to allow instead of replacing with underscores.
