Customizing default option names provided with AutoHelpMixin

[laurentpellegrino]

I a using mixinStandardHelpOptions with a command and subcommands. This is really convenient. The issue I have is that this mixin adds a version option with default names defined as -V, --version whereas I would like to get -v, --version.

Looking at Picoli implementation, I see there is a placeholder defined in CommandLine.AutoHelpMixin:

@Option(names = {"${picocli.version.name.0:--V}", "${picocli.version.name.1:---version}"}, versionHelp = true, descriptionKey = "mixinStandardHelpOptions.version", description = "Print version information and exit.")
private boolean versionRequested;

Setting System.setProperty("picocli.version.name.0", "-v"); in my app main is working but there seems to be no mention about Picocli placeholders in the docs. Is this the recommended way to proceed?

Yes, well-spotted.
if you feel like helping improve the docs that’d be great.
