NAME ^

StateML::Utils - Some handy utility functions

SYNOPSIS ^

    use StateML::Utils qw( empty as_string );

DESCRIPTION ^

Some handy uti.... you get the idea.

FUNCTIONS ^

empty

Returns TRUE if the single arg is not defined or of zero length. "0" is not empty. This does not have a prototype like defined() or length() because the precedance can't be set properly. Tests $_ if no parameters are passed.

as_str
    warn as_str "hey!", undef.

Converts the list of parameters to a string, quoting plain scalars if need be and reporting them as undef if they are undefined. May handle other situations/structures in the future.

Does an implicit join( "", ... ) in scalar context.
