Multiline help output possible?

[jh125486]

I searched through the code how the help text is populated for an arg, but didn't really see anyway to have a multiline output, e.g.:

--config-yaml="yaml string"                 The YAML string for a bootstrap configuration. If --config-path is also set, the values in 
                                            this YAML string will override and merge with the bootstrap loaded from --config-path. 
                                            Because YAML is a superset of JSON, a JSON string may also be passed to --config-yaml.

                                            Example overriding the node id on the command line:
                                            ./envoy -c bootstrap.yaml --config-yaml "node: {id: 'node1'}"

Anyone have any tricks to accomplish this?

Have you tried putting a \n in the help string? That would still make for an incredibly unwieldy tag though.

Yeah, tried a “\n”… just printed a raw “\n” in the text. Even tried defining a separate var (as “\n”) to interpolate into the help text… that inserted an actual new line, but made the help wrap super wonky unfortunately. When I get back to my desk, I’ll try aliasing a type, and put a new line into the Help() method on that alias. Kong is literally the best CLI package for Go by the way, thanks for putting in the time to make this. V/r Jacob Hochstetler
