Some utils to simplify testing.

End-users do not need to call the methods in this module.


This module is available as a Unix-style distro (*.tgz).

See for help on unpacking and installing distros.


Install GraphViz2 as you would for any Perl module:


        cpanm GraphViz2

or run:

        sudo cpan GraphViz2

or unpack the distro, and then either:

        perl Build.PL
        ./Build test
        sudo ./Build install


        perl Makefile.PL
        make (or dmake or nmake)
        make test
        make install

Constructor and Initialization

Calling new()

new() is called as my($obj) = GraphViz2::Filer -> new(k1 => v1, k2 => v2, ...).

It returns a new object of type GraphViz2::Filer.



Returns a hash (sic) keyed by *.pl name, with the values being the text off line 3 of each script.

This text is used to annotate html/index.html, the output of scripts/

get_files($dir_name, $type)

Returns a list of files from the given $dir_name, whose type (extension) matches $type.

See t/tokens.t.


Returns a hash (sic) keyed by *.pl name, with the values being the full path to the script.


Many thanks are due to the people who chose to make Graphviz Open Source.

And thanks to Leon Brocard, who wrote GraphViz, and kindly gave me co-maint of the module.
