dvm list default behaviour

[marblegravy]

dvm list on it's own throws an error in 2.3

| => dvm list
FATA[0000] expected 1 argument, 0 found

Suggest it's default behaviour triggers help text to describe the available flags. Perhaps something like:

| => dvm list -h
List available or installed Drush versions.

Usage:
  dvm list [commands] [flags]

Commands:
  available    Lists all versions of drush that can be installed
  installed     Lists all versions of drush that are already installed

Flags:
  -h, --help   help for list

Global Flags:
      --config string   config file (default is $HOME/config.toml)

I'd love to do this - I just need to figure out how to invoke it from a subcommand...

It would help me out in a number of other places.

Edit: figured it out :)

Commit it on the way.

Any templating changes will need to be templated or otherwise handled.

So this achieves the desired result, the program knows about the flag, rather than it being arbitrary.

Please leave some feedback when you find some time.

Please advise of any further change within the next week - I'm looking at releasing v2.4.0.

• Have the changes improved the intent of this issue?
• Was it intended to set the default behaviour to list available, or installed versions where no flag is provided, and if so, which option would be preferable?
