** Modules

Many modules are broken with Perl 5.26 by the removal of the current directory <code>.</code> from <code>@INC</code>. See the [[http://blogs.perl.org/users/todd_rinaldo/2016/11/how-removing-from-inc-is-about-to-break-cpan.html][blog post]] from Todd Rinaldo
for more information.

** Fix the problem on GitHub

Released Perl modules can be found on Github under [[https://github.com/gitpan]].

We can fork the gitpan repository for the broken module, e.g. for <code>String::CamelCase</code> I forked [[https://github.com/gitpan/String-CamelCase]] to 
[[https://github.com/racke/String-CamelCase]].

Now clone it on your own machine:

<example>
git clone git@github.com:racke/String-CamelCase.git
</example>

For this module, there is already an patch available. So I did apply it
as follows:

<example>
wget https://rt.cpan.org/Ticket/Attachment/1702614/914478/String-CamelCase.patch
cd String-CamelCase
patch -p 1 < ../String-CamelCase.patch
</example>

Next step is to test the result:

<example>
perl Makefile.PL
make test
</example>

If that works, we can publish the patch. Also, I attributed the author
of the patch.

<example>
git add Makefile.PL
git commit --author="Jim Keenan <jkeenan@cpan.org>" -m "Add current directory to @INC (RT #120079)"
git push
</example>

Now everyone can install the patched module as follows:

<example>
cpanm git@github.com:racke/String-CamelCase.git
</example>

*** String::CamelCase

Last release in 2009. Problem [[https://rt.cpan.org/Public/Bug/Display.html?id=120079][reported]].

<example>
