Welcome to the picocli discussion group! Feel free to post questions, ideas for new features, design discussions, etc. Any topic related to command line and shell interfaces that you think may be interesting for the picocli community is welcome.

If you have a GitHub account, consider raising an issue on the picocli issue tracker instead.

As the picocli maintainer I found that this makes it easier for me to track requests. Conversations on this list may drop off the inbox horizon without follow-up.
