Issue Reference: https://github.com/spf13/cobra/issues/1056https://github.com/spf13/cobra/pull/922 introduced a new error
type that emitted when a command was not runnable. This caused
all commands w/o a run function set to error w/ that message and a status code of 1.
This change reverts the addition of that new error. Similar
functionality can be accomplished by leveraging RunE.
As discussed in golang/go#26109, vet typecheck is enabled
in go1.11 and the command_test.go can't be compiled any
more with go1.11 due to the unread variables in the
command_test.go.
Instead of removing the unused variables, this CL reads the
variables and compares the values against the current
behavior so when the related issue is fixed, this test can
be updated accordingly.
* Add `CalledAs` method to Command (w/ tests)
The `CalledAs` method returns the name of the command or alias that
invoked the command -- as long as the command was actually invoked.
Otherwise, it returns the empty string.
The opens up possibilies for commands to behave differently based on
which alias invoked the command (in the same vein as Linux programs
which adjust their behavior based on the value of argv[0]).
* Fixed formatting
Make it so that, in the case that the root command is not runnable
but has subcommands, specifying a '--version' flag will still
run the "version" behavior.
* Fix shellcheck
Before this change:
In - line 204:
declare -F $next_command >/dev/null && $next_command
^-- SC2086: Double quote to prevent globbing and word splitting.
--- FAIL: TestBashCompletions (0.34s)
bash_completions_test.go:138: shellcheck failed: exit status 1
* Avoid storing pointer to nil
Before this change, the new test fails with:
--- FAIL: TestSetOutput (0.00s)
command_test.go:198: expected setting output to nil to revert back to stdout, got <nil>
The default pflag error is to only print the bad flag. This enables an application
to include a usage message or other details about the error.

Added the ability to have hidden commands that cobra will still run as intended, however they won't show up in any usage/help text
adding internal field to command
private is a better name
hiding private commands in default help/usage
opting for 'hidden' over 'private'
updating all 'help command' checks to exclude hidden commands
updating how commands are displayed in usage/help text by updating/adding some methods. added tests for hidden/deprecated commands
making command hidden when testing hidden command execution
test now leverage the included suite and are much less custom. also removed deprecation tests, once I discovered them in cobra_test.go
updating hidden command test to be more reliable
removing unnecessary () when checking len(c.Deprecated)
updating command comments to be godoc friendly
