optparse-applicative v0.16.0.0 Release Notes

Release Date: 2020-08-14 // over 3 years ago

    • ➕ Add Options.Applicative.NonEmpty.some1 function, which parses options the same as some1 from base, but doesn't cause duplicates in the usage texts.

    • Further improve help text generation in the presence of optional values when nesting is involved, and many and some when displayed with a suffix.

    • ➕ Add "global" options to the usage texts for subcommands. When using subcommands, a "global options" section can now appear below the options and commands sections.

    Global options are off by default, to enable them, use the helpShowGlobals modifier.

    The noGlobal builder will suppress a single option being displayed in the global options list.

    Fixes issues: * # 175 - List detailed subparser documentation with --help * # 294 - Displaying global options when listing options for a command. * # 359 - Subcommand help text lacks required parent command arguments

    • 👍 Allow the --help option to take the name of a command. Usage without any arguments is the same, but now, when an argument is given, if it is the name of a currently reachable command, the help text for that command will be show.

    Fixes issues: * # 379 - cmd --help subcmd is not the same as cmd subcmd --help

    • ⚡️ Updated dependency bounds.

    • ➕ Add builder for the all positional parser policy.
