mopen

NAME

mopen, mopen1 - Application launcher (including Mono, Moonlight and Silverlight).

SYNOPSIS

mopen [options] file [arguments...]

DESCRIPTION

The mopen command is a tool to open applications, XAML files or packages that contains executables, images and other resources in a directory, it is designed to launch Silverligh 2.0 applications. For testing only 1.0 applications use the mopen1 command.

In addition to launching these applications, it is possible to run multiple applications using the same Mono virtual machine. This is useful for example if you want to run a collection of small applications, gadgets or widgets and do not want to pay the price of memory consumption of running one entire virtual machine for every application. This is achieved by using Mono Application Domains: the equivalent to processes within a Mono virtual machine, and it is the same infrastructure used by ASP.NET applications to run multiple isolated applications in the same virtual machine.

In its simplest incarnation, you can open a XAP file like this:

 
         $ mopen /opt/myapp/test.xap
 
 

This will load the test.xap file which is a self-contained Silverlight application.

It is possible to also load 1.0-style Silverlight applications by passing it a XAML file and using the mopen1FP command instead:

         $ mopen1 /opt/myapp/test.xaml
 

This will laod the xaml file and all of the dependencies it might have from the directory where test.xaml is located.

mopen also supports launching these applications if they are contained in a directory thta is on the PATH and such directory contains a file called "default.xaml" or "main.exe".

In the case of applications that start up from XAML, the default size of the window will be the one specified for the Canvas unless the --geometry option has been used

With this configuration it is possible to have entire applications that are packaged in a directory and can be deployed and copied by copying the entire directory (drag and dropping the directory, using cp -a, or any other mechanism to copy a directory).

OPTIONS

The following options are available:

--debug

Passes the flag --debug to the Mono runtime, enabling a line numbers and a couple of other debugging features.

--gdb

This starts up Mono with gdb and prints out the command that you should use to debug mopen. This is useful when debugging XAML files that cause problems with Moonlight.

--desklet, -d

Turns on desklet mode. In this mode the window decoration is not shown and the default rendering mode will enable alpha transparency. This means that anything painted with an alpha channel will be properly transparent.

-f, --fixed

Makes the toplevel window fixed, prevents the user from resizing it.

--geometry=GEO, -g GEO

Sets the geometry of the window to be GEO, the format for this is WIDTHxHEIGH where WIDTH and HEIGHT are integers, for example:

 
         mopen -g 1024x768
 
 

--host NAME

Loads the application into the host identified by NAME. If no host is specified this application is loaded into its own virtual machine and can not be shared with others.

--stories, -s

Triggers one by one all the named Storyboards in the given XAML file when you click on the canvas surface.

--parseonly, --parse-only

Parse the XAML file but does not open a window. Useful for testing.

--story=N1[,N2]

Runs the storyboard named N1 when the mouse is clicked (this is the x:Name property on the XAML file). The storyboard playback will cycle if you keep clicking. You can use it like this:

       mopen --story FadeIn demo.xaml
        mopen --story FadeIn,FadeOut demo.xaml
        mopen --story FadeIn --story FadeOut demo.xaml

--transparent, -t

Enables the alpha channel on the rendering surface. Any areas that are rendered with non-opaque values will be properly composited against the underlying background by the system compositing manager.

--timeout=X

Close the mopen window after X seconds. Useful for testing.

SHARING A VIRTUAL MACHINE

To load multiple independent applications into a single virtual machine (the virtual machine will isolate each application from each other using Application Domains, or AppDomains) you use the --host option with the name of the domain where you want to load your application.

For example, if you wanted to load various desktop gadgets on a single process, you would load them like this:

 
         mopen --host desktop calendar
         mopen --host desktop stocktracker
         mopen --host desktop flicker-best-images
         mopen --host desktop cute-clock
 
 

You could load a separate set of programs on another VM, for example while developing code that might be unstable:

 
         mopen --host devel mytestapp
 
 

To load a desklet, you would use:

 
         mopen --desklet mydesklet
 
 

FILES

When a file is specified, if it exists on the current directory, that one is loaded, otherwise directories on the PATH are searched and if they contain the file default.xaml or the file main.exe Those are loaded and launched
