text/template based help-generation:
$ example help example
`example` is a CLI app built with patroclos/go-conq.
example [commands] [options] arguments
example help [commands|subjects]
Commands:
- help
- completion
- foo
- bar
conq contains Option instances (conq.O struct), these stand for flag-parameters and positional-arguments and are usually used with the generic Opt[T] and ReqOpt[T] types, which implement parsing for scalars and types implementing encoding.TextUnmarshaler. See example to see interesting standard-library types that can just be used as-is, things like IP, Mac-Addresses, etc.
The biggest focus of conq is composability. Eventually there should even be standardized tree-operations to run on a Cmd-tree, like wrapping help-sections, marking deprecations, etc.
The standard help command is just another command-package in aid/cmdhelp,
and can be replaced completely, changing how help is resolved from multiple sources
and rendered.
Parameters are something special in conq. They have a name (ie a 'depth' parameter).
There is a builtin getopt conq.Optioner implementation. It enables extraction and
completion of getopt-style flags, and is also completely modular. You can make your
own parameter-style extractor.
