I have an offline CPAN archive. Sometimes it happens that I have to update a module there. For example some weeks ago I used the module Mojo::DOM; for some XML stuff. Later I wanted to pack my script with pp. But it didn't work. Investigating a little bit showed up that a new version of Module::ScanDeps fixes the issue. But this new version is not in CPAN, but in a private github of the author.

So I decided to update Module::ScanDeps Version 1.31 in my offline CPAN with the new version 1.32 from Github.

I did it as follows.

  1. download ModuleScanDeps 1.32 from Github and put in the correct folder in my offline cpan
  2. update 02packages.details.txt.gz, i.e. replacing Module::ScanDeps 1.31 R/RS/RSCHUPP/Module-ScanDeps-1.31.tar.gz to Module::ScanDeps 1.32 R/RS/RSCHUPP/Module-ScanDeps-1.32.tar.gz
  3. update RECENT file, i.e. authors/id/R/RS/RSCHUPP/Module-ScanDeps-1.31.tar.gz to authors/id/R/RS/RSCHUPP/Module-ScanDeps-1.32.tar.gz
  4. update CHECKSUMS file by using use CPAN::Checksums qw(updatedir); updatedir("./cpan/sources/authors/id/R/RS/RSCHUPP");

It worked well. But I don't want to do so many steps manually each time I want to update a module in my offline CPAN. Furthermore CPAN::Checksums works only on Linux for me and not on Windows. Of course I could script the steps above by myself. But I think it is a bad idea to reinvent the wheel. For such a basic problem I'm sure there has to be a good solution out there.

So my question is. What is the best way to update a module in an offline CPAN?

Thank you very much in advance!
