- 5. . WHO’S PINTO? . . . “an application for creating and managing a custom CPAN-like repository of Perl modules” .
- 6. . COMMON DEV PROBLEMS . • how to distribute internally in-house developed modules which are not on CPAN? (e.g. confidential, too specific, …) • how to distribute internally a (temporarily) patched third-party module?
- 7. . COMMON DEV PROBLEMS . • how to keep track of which versions of your app’s dependencies are safe? (and how to make them available) • how to keep track of which versions break your app?
- 8. . COMMON DEV PROBLEMS . • how to quickly replicate the production/testing/development environment? • how to efficiently ensure that everybody is using the same versions of the dependencies?
- 9. . SO WHAT? With Pinto you can: • keep one or more instances of privates CPAN-like repos • distribute in-house modules using the standard tools from the CPAN ecosystem • simultaneously manage dependencies for multiple apps/projects • pin specific versions of module to fix broken dependencies .
- 10. . PINTO ADVANTAGES . • supports multiple indexes • helps manage incompatibilies between dependencies • has built-in version control • can pull archives from multiple remote repositories • supports team development
- 11. . . USAGE 1. create a Pinto repository 2. pull CPAN modules, add your own, freeze versions, … 3. point your /cpan(m|p)?/ to your Pinto repo when installing your app’s dependencies 4. repeat steps 2 and 3 throughout project’s lifecycle .
