php - Show help text when command encounters error -

i have working command. want add options it. none of these options technically required, at least , at most 1 of them needs supplied single invocation of command. have options set , can detect these circumstances.

however, wish show dialog command whenever check fails. if command my:command, want output of running $ php artisan my:command -h display after error message.

i have tried doing this:

$this->error('my error message');  // causes infinite failness since calling command not passing  // options (or ignoring it), hitting same error condition $this->call('my:command', ['-h' => true]);   // causes.. nothing. no error, no blank line, see error message artisan::call('help', ['command_name' => 'my:command', 'format' => 'txt']);  // both of these cause nothing displayed. from: // symfony\component\console\command\command echo $this->gethelp(); echo $this->getprocessedhelp(); 

is there way same formatted text of command or trigger message display when error encountered?

update

the default output command when running $ php artisan my:command this:

usage: my:command [options] [--] [<argument>]  options:   -h, --help             display message   -q, --quiet            not output message   -v, --version          display application version       --ansi             force ansi output       --no-ansi          disable ansi output   -n, --no-interaction   not ask interactive question       --env[=env]        environment command should run under.   -v|vv|vvv, --verbose   increase verbosity of messages: 1 normal output, 2 more verbose output , 3 debug 

i want output after error message.

to show message after error add after error message line

$this->call('help', ['command_name' => 'test:mycommand', 'format' => 'raw']);
