optparse-applicative v0.16.1 Release Notes

Release Date: 2020-11-20 // about 1 year ago

Previous changes from v0.16.0

    ➕ 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.

    ✂ Remove deprecated functions

    • nullOption
    • execParserMaybe
    • customExecParserMaybe
