Jeff Lowdermilk 5c9146990b Explicitly support local flags overwriting persistent/inherited flags 
The current (desired) behavior when a Command specifies a flag that
has the same name as a persistent/inherited flag, is that the local
definition takes precedence. This change updates the various
Flag subset functions to respect that behavior:
* LocalFlags: now returns only the set of flags and persistent flags
  attached to the Command itself.
* InheritedFlags: now returns only the set of persistent flags inherited
  from the Command's parent(s), excluding any that are overwritten by a
  local flag.
* NonInheritedFlags: changed to an alias of LocalFlags.
* AllPersistentFlags: removed as not very useful; it returned the set
  of all persistent flags attached to the Command and its parent(s).

Default UsageTemplate updated to use LocalFlags and InheritedFlags

Étienne Vallette d'Osia fd2b84c4e2 Add Command's RemoveCommand method 
This method removes children commands of an existing command.

This allows to build CLI clients that can be extended by 3rd party tools,
for instance by adding commands _and replacing the “version” command_.

For now the 1st defined command will be executed, so it is not possible
to override an existing command. But anyway, deleting old command then
adding a new one is the ultimate way to be certain there is no
confusion.

Eric Paris bf480fe628 New "example" section of commands 
We have a long and short description.  This adds an "Example" section.
Which can used to create better docs than putting it all in Long.

Anthony Fok 4745f1fd64 In execute(), check if command is Runnable() 
A corner case exists where c.Runnable() is not checked
before c.Run() is called, thus a nil c.Run is executed
leading to "panic: runtime error: invalid memory address
or nil pointer dereference".

This patch adds an extra c.Runnable() check in execute()
to catch that corner case.

Fixes #37.

Steve Francia b825817fc0 Merge pull request #32 from smarterclayton/hide_subcommand_help_for_root_only_command 
When no subcommands are registered, omit command help output
 2014-11-12 16:52:16 -05:00
Clayton Coleman 9b6c92647a When no subcommands are registered, omit command help output 
For a single root command with a Run method, the help output still
contains 'help [command]' as a subcommand (because Help is always
added). Since the only subcommand would be 'help', the help is better
off omitted.

This change allows a command to be used both as a subcommand
or a root command without having to define a custom help that elides
the help command when no subcommands are added.  Instead, the default
help command is only added when subcommands are present.

tummychow 667c348dbd Test behavior for subcommand with same name as root command 
If, for some reason, you have an application with some name "foo", and your
app has a subcommand "foo", cobra should behave properly when you call
"foo foo", and it should also behave if you call "foo f".

These changes verify both of these cases and ensure cobra responds properly.

tummychow 96d543cf2c Reset root command lists in testing 
This fixes some issues that appear when testing prefix invocations. Since the
root command lists weren't being cleared, the list would persist between
tests, so there would be multiple instances of each command. Then, if you
tried to match a prefix of one of those commands, you'd get two matches (one
for each instance) and the command would fail.

Resetting the root command lists prevents them from persisting between tests,
resolving this issue.

tummychow f4c075f8f8 Add command name prefix matching 
A command can now be invoked with a prefix of its own name, assuming that
prefix is unambiguous (ie it isn't also a prefix of any sibling command's
name).
