the output should look like this: : FvwmRingMenu starting upĪ Quick Tip: You can run modules that use fvwm-perllib from the command line. Now you should be able to launch the module in the usual way. Somewhere in your ModulePath and make it executable with chmod +x FvwmRingMenu

Now stick the code in a file called FvwmRingMenu and put the file $mod->showMessage( 'Message Received: $text' ) # add a handler for string events - this is the SendToModule event $module->showMessage('FvwmRingMenu starting up') So, purely in the interests of testing, let’s add a bit of chatter.Īdd this in just ahead of the eventLoop call: # Since we haven’t defined any event handlers, this module does nothing expect sit there using up a slot in the process table.

When an event does occur, it looks to see if a handler routine has been defined for that event, if so, calls it. This is an infinite loop that waits for FVWM events to occur. Most of the methods you need to write the module are available through this object.Ĭalls the module event loop. This creates an object that handles the FVWM module protocol. That fvwm-perllib command is useful for other things as well. So the “use lib” line says to perl to add /usr/share/fvwm/perllib (on my machine anyway) to the list of places to look for perl modules. With my command prompt tagged onto the end, because it doesn’t add a newline. Backquotes in perl work the same as they do in bash - the enclosed string gets executed as if from the command line, and the output of the command is substituted for the quoted expression. The FVWM::Module line includes the FVWM::Module module, while the use lib `fvwm-perllib dir` So, the “use” lines are about perl modules.

Having explained the distinction, it should be fairly clear when I’m talking about perl mods and when I mean fvwm. they end in “.pm” and get included in a program with the “use” command. Perl modules are files with chunks of perl inside.

OK, I can see we better talk about the use of the word “modules”. Then the “use” lines tell perl where to find the FVWM modules and to include the perl module that implements the basic FVWM module interface for Perl. The first two lines tell the the OS to where to find the perl executable and turn on lots of useful error checking that’ll stop you making some really stupid mistakes. It’s a bit simpler than it’s written-in-C counterpart That’s a basic, goes-nowhere, does-nothing FVWM module written in perl. Use strict get the directory with the FVWM perl mods, then include the basic fvwm perl module OK? Then let’s go.Ī skeletal module in perl looks a bit like this: If fast enough, it may be too clumsy to be useful. I’ve not written this module yet, so I have no idea if this will work. I mean the cool circular icon menus from Neverwinter Nights, not the naff curses menus from lotus and informix. What I want to do is implement a ring menu extension. There seems to be some interest - let’s do a Perl module.
