Carton

  • carton install
    • Install modules locally
    • Collects artifacts (metadata)
    • Dumps versions to the snapshot file
  • carton install --deployment
    • Recreate CPAN mirror from the snapshot
    • installs modules with cpanm

Carton 1.0

  • carton install
    • runs cpanm --installdeps ...
    • collects install.json (generated by cpanm)
    • dumps cpanfile.snapshot
  • carton install --deployment
    • generates 02packages.details.txt from cpanfile.snapshot
    • runs cpanm --installdeps --mirror-index ...

Problems

  • install.json generation is fragile
  • relies heavily on cpanm internals
  • incomplete git support
  • incomplete vendor support

Carton 2.0

  • Same command line interface
  • More focused on mirror management (like Pinto, Parcel)
    • with vendor support
  • Extract module resolutions out of cpanm
  • Extract package analyzer out of cpanm
