NAME

Code::TidyAll::Role::RunsCommand - A role for plugins which run external commands

VERSION

version 0.76

SYNOPSIS

    package Whatever;
    use Moo;
    with 'Code::TidyAll::Role::RunsCommand';

DESCRIPTION

This is a a role for plugins which run external commands

ATTRIBUTES

cmd

The command to run. This is just the executable and should not include additional arguments.

METHODS

_run_or_die(@argv)

This method run the plugin's command, combining any values provided to the plugin's argv attribute with those passed to the method.

The plugin's argv attribute is parsed with the shellwords subroutine from Text::ParseWords in order to turn the argv string into a list. This ensures that running the command does not spawn an external shell.

The @argv passed to the command comes after the values from argv attribute. The assumption is that this will be what passes a file or source string to the external command.

If the command exits with a non-zero status, then this method throws an exception. The error message it throws include the command that was run (with arguments), the exit status, any signal received by the command, and the command's output.

Both stdout and stderr from the command are combined into a single string returned by the method.

_is_bad_exit_code($code)

This method returns true if the exit code is bad and false otherwise. By default all non-zero codes are bad, but some programs may be expected to exit non-0 when they encounter validation/tidying issues.
