The Dumbbench module

This is the README for the Dumbbench Perl module. You're probably looking at this because you don't know where else to find what you're looking for. Read this once and you might never have to read one again for any Perl module.


To read about Dumbbench, look at the embedded documentation in the module itself. Inside the distribution, you can format it with perldoc:

% perldoc lib/

If you have already installed the module, you can specify the module name instead of the file location:

% perldoc Dumbbench

You can read the documentation and inspect the meta data on one of the CPAN web interfaces, such as CPAN Search or MetaCPAN:

The standard module documentation has example uses in the SYNOPSIS section, but you can also look in the examples/ directory (if it's there), or look at the test files in t/.


You can install this module with a CPAN client, which will resolve and install the dependencies:

% cpan Dumbbench
% cpanm Dumbbench

You can also install directly from the distribution directory, which will also install the dependencies:

% cpan .
% cpanm .

You could install just this module manually:

% perl Makefile.PL
% make
% make test
% make install

You probably don't want to do that unless you're fiddling with the module and only want to run the tests without installing anything.

Dumbbench::BoxPlot install

If you want to use Dumbbench::BoxPlot (check it's Pod for details), you will need to add more software than is initially required to just run Dumbbench.

First, you need to provide development headers for the ROOT application. How to install depends on your operational system requirements. For Ubuntu 16.04, installing the following packages will do:

sudo apt-get install libroot-gui-dev libroot-graf3d-g3d-dev libroot-graf3d-gl-dev libroot-graf2d-postscript-dev libroot-math-physics-dev

After that, you will need to install the SOOT distribution, which provides a Perl binding for ROOT. Once you have the required development headers and libraries, you just need to repeate the same steps already described for installing Dumbbench:

% cpanm SOOT

Source location

The meta data, such as the source repository and bug tracker, is in Makefile.PL or the META.* files it creates. You can find that on those CPAN web interfaces, but you can also look at files directly in the source repository:

If you find a problem, file a ticket in the issue tracker:

Getting help

Although I'm happy to hear from module users in private email, that's the best way for me to forget to do something.

Besides the issue trackers, you can find help at Perlmonks or Stackoverflow, both of which have many competent Perlers who can answer your question, almost in real time. They might not know the particulars of this module, but they can help you diagnose your problem.

You might like to read brian's Guide to Solving Any Perl Problem.

You should have received a LICENSE file, but the license is also noted in the module files. About the only thing you can't do is pretend that you wrote code that you didn't.

Good luck!
