picocli v4.1.2 Release Notes

Release Date: 2019-12-08 // over 4 years ago

  • Picocli 4.1.2

    The picocli community is pleased to announce picocli 4.1.2.

    🛠 This release contains bugfixes, improvements, and documentation enhancements.

    This version of picocli requires JLine 3.13.2 or higher and adds a PicocliCommands class that provides command descriptions that can be displayed in the terminal status bar via the new JLine TailTipWidgets functionality.

    The built-in picocli.AutoComplete.GenerateCompletion (generate-completion) subcommand now omits validation of mandatory options in the parent command.

    "Hidden" subcommands and options are no longer shown as suggestions in unmatched argument usage help or autocompletion scripts.

    From picocli 4.1.2, all options in an exclusive group are automatically considered required, even if they are not marked as required = true in the annotations. Applications using older versions of picocli should mark all options in exclusive groups as required.

    🚀 This is the sixty-fourth public release.
    Picocli follows semantic versioning.

    Thanks to the Community

    Special thanks to mattirn and to Andreas Deininger for the pull requests and feedback!
