8b46886de8 added flag to have a custom text on the USAGE section of help 2015-10-24 23:37:21 -06:00
Ryan Graham
732e97aee8 only display app version and help message once 
When processing the flags for -h/--help and -v/--version, only check
the flags in checkVersion() and checkHelp() instead of also printing
the associated message.

This fixes the problem of `app -h` and `app -v` printing their output
twice. The doubling was caused by printing the message once for each
registred alias for the given flags (-h/--help and -v/--version).

Resolves #285

Added exit code support 
Now the exit code can be returned by BeforeFn, ActionFn and AfterFn.

The `os.Exit` function is not called by this packaged

This closes #66 and closes #164

subcommand.

2272dad83e Version and help check should look for local flags too 
Now that Global looks up the chain of contexts, the top level should
access the flags without the prefix (i.e. Bool rather than GlobalBool).

e842547421 Readd printHelp function back 
But update signature to take a writer. This is a backwards incompatible
change for those overriding the HelpPrinter, but the hope is that this
feature is largely unused and the usage is easily updated.

4be878bffc Fixing the issue with a command with subcommands not showing help message. 
- the command name is "" and HasName was returning true for an empty
  ShortName.
- the Show method wasn't aware that command name was just "" and
  returned the first subcommand.
