Q:

List all available tags in Cucumber

Is there a command line option to list all the tags in your cucumber test suite?
For example, I would want something like:
cucumber --show-tags foo.feature

That would give me something like:
@ci
@development
@regression
@wip

A:

For a single file:
cucumber -f tag_cloud foo.feature

You could also find the tags of all features in a directory:
cucumber -f tag_cloud features/login

Or even features that are shared with a particular tag:
cucumber --format tag_cloud --tags @bvt

The output generated for all these is a wiki style table:
| @baseline | @customer | @demographics | @performance |
| 1         | 1         | 1             | 1            |
