dab adds package dependencies to your pubspec, saving you a trip to pub.dev to look up the latest version.


Assuming the Dart SDK is available on your $PATH, to install (or update) the top-level dab command, run:

$ pub global activate dab


$ dab help

-h, --help         Print this usage information.
    --[no-]scp     Write ssh URLs with scp syntax.
                   (defaults to on)

-f, --filename     Pubspec file to edit
                   (defaults to "pubspec.yaml")

-n, --dry-run      Only print the modified pubspec, without overwriting the file.
-s, --[no-]sort    Sort list output alphabetically.
                   (defaults to on)

known issues

  • TODO: error handling
  • TODO: tests
  • It WILL eat the executables section, pending dart-lang/pubspec_parse#49.
  • It WILL eat comments.
  • It WILL sort dependencies alphabetically.

It's always a good idea review the changes: git diff pubspec.yaml.


Run tool/gen_{once,watch} to update the generated code *.g.dart. This is idempotent.
