JCommander

[jcommanderguy]

I  want  to actually  print the  usage  when  the  user  launches  the  app without  passing  any  options

app.exe

< should  print usage>

I  dont  see a  way  to  indicate  jcommander  to  do  this.

Also  another  question. Is there  in  built  support  for  showing  the  usage when  user  types  app.exe -help

or  do  I  have  to explicitly process a  help option by  adding  the  below to  the  main options?

@Parameter(names = "--help", help = true)

private boolean help;

Thanks,
Vips

Create a new JCommander object and call usage() on it?

"You need to do this ^^^ "

Can  you  elaborate?

I was pointing "up" to the code that you pasted:

@Parameter(names = "--help", help = true)

private boolean help;
