NAME

Verby::Action::RunCmd - a base class for actions which exec external commands.

SYNOPSIS

use base qw/Verby::Action::RunCmd/; # not usable on it's own

sub start {
	my ($self, $c) = @_;
	blah();
	$self->cmd_start($c, [qw/touch file/]);
}

DESCRIPTION

METHODS

run @args_for_cmd_start

The method to be used by your action's do method when appropriate.

Basically a thin wrapper arund cmd_start and cmd_finish, that lazy people will like.

cmd_start $cxt, \@command_line, [ \%opts ]

The method to be used by your action's start method when appropriate.

The first parameter is the context, as is typical in Verby.

The second parameter is an array reference of the command line to invoke. This is passed verbatim to IPC::Run.

The third, optional parameter, is a hash reference of options.

The option fields that you can use are

init

A code reference, corresponding to IPC::Run's init parameter.

log_stderr

A boolean (true by default), that causes the STDERR handler to be a delegate to the logger.

log_stdout

The same as log_stderr but for STDOUT. False by default.

in

A parameter to be passed as the input to IPC::Run. This can be a string ref, a code ref, or, whatever. See IPC::Run's docs.

cmd_finish

The inverse of cmd_start - causes an OS image to be restored, for the time just prior to the invocation of cmd_start. Only works on the EROS operating system.

On other operating systems, it waits for the child process to finish.

finish

A default implementation of "finish" in Verby::Action that'll call cmd_finish and then "confirm" in Verby::Action.

pump

See if the process finished. Part of the Verby::Action async interface.

log_extra

A method that given the context might append something to log messages. used by Verby::Action::Make, for example.

log_invocation

Mostly internal - the default implementation of the logging operation used when invoking the subcommand.

BUGS

None that we are aware of. Of course, if you find a bug, let us know, and we will be sure to fix it.

CODE COVERAGE

We use Devel::Cover to test the code coverage of the tests, please refer to COVERAGE section of the Verby module for more information.
