to_identifier 'foo-bar', '_';        # foo_dash_bar
to_identifier 'foo.bar', '_';        # foo_dot_bar
to_identifier "foo\x{4EB0}bar";      # fooJingBar
to_identifier "foo\x00bar";          # fooNullCharBar
to_identifier "foo\x00\x00bar";      # foo2NullCharsBar
to_identifier "foo\x00\x00bar", '_'; # foo_2_null_chars_bar

{
    no utf8;
    to_identifier "foo\xFF\xFFbar.baz";      # foo_2_0xFF_BarDotBaz
    to_identifier "foo\xFF\xFFbar.baz", '_'; # foo_2_0xFF_bar_dot_baz
}

#DESCRIPTION

This module provides a utility method, "to_identifier" for converting an arbitrary string into a readable representation using the ASCII subset of \w for use as an identifier in a computer program. The intent is to make unique identifier names from which the content of the original string can be easily inferred by a human just by reading the identifier.

If you need the full set of \w including Unicode, see the subclass String::ToIdentifier::EN::Unicode.

Currently, this process is one way only, and will likely remain this way.

The default is to create camelCase identifiers, or you may pass in a separator char of your choice such as _.

Binary char groups will be separated by _ even in camelCase identifiers to make them easier to read, e.g.: foo_2_0xFF_Bar.

#EXPORT

Optionally exports the "to_identifier" function.

#SUBROUTINES

#to_identifier

Takes the string to be converted to an identifier, and optionally a separator char such as _. If a separator char is not provided, a camelCase identifier will be returned.

#METHODS

#string_to_identifier

The class method version of "to_identifier", if you want to use the object oriented interface.
