However, if you do so you must take care of propper encoding yourself. Optionally you can pass a custom ARGV to this constructor my $obj = MyApp->new_with_command( ARGV => ) You can pass a hash of default/fallback params to new_with_command my $obj = MyApp->new_with_command(%default) If it fails it returns a MooseX::App::Message::Envelope object holding an error message. This constructor reads the command line arguments and tries to create a command class instance. METHODS new_with_command my $myapp_command = MyApp->new_with_command() Read the Tutorial for getting started with a simple MooseX::App command line application. HashRef: Specify multiple key value pairs ('-opt key=value -opt key2=value2', also see app_permute) The following type constraints are supported:ĪrrayRef: Specify multiple values ('-opt value1 -opt value2', also see app_permute and cmd_split)
Moose type constraints help MooseX::App to construct helpful error messages and parse in a meaningful way. Positional parameters are defined with the 'parameter' keyword parameter 'some_option' => (Īll keywords are imported by Moosex::App (in the app base class) and MooseX::App::Command (in the command class) or MooseX::App::Simple (single class application).įurthermore, all options and parameters can also be supplied via %ENV option 'some_option' => (Ĭmd_env => 'SOME_OPTION', # sets the env key However such options must have a Boolean type constraint. Single letter options are treated as flags and may be combined with each other.

Just take any existing Moose class, add a single line ( use MooseX-App qw(PluginA PluginB. MooseX-App is a highly customisable helper to write user-friendly command line applications without having to worry about most of the annoying things usually involved. help -usage -?

Packackes in the namespace may be deeply nested. Write multiple command classes (If you have only a single command class you should use MooseX::App::Simple instead). For example, a parameter sweep of an S-parameter analysis.MooseX::App - Write user-friendly command line apps with even less suffering SYNOPSISĭocumentation => q, However, it can be used to swap the orders of the independent, even if the dependent is a matrix. The permute() function cannot be used to swap the rows and columns of a matrix.
The permute() function can be used for this purpose. To swap the order so that it can be easily plotted, the order of the independents must be swapped. For example, a data could have two independent variables in a particular order. The permute() function is used to swap the order of the independent variables that are attached to a data variable. Any N-dimensional square data (all inner independents must have the same value N)Īny permutation vector of the numbers 1 through N †
