Title: Squirrel script to change display.
Post by: TheFirstAv3nger on February 04, 2017, 06:01:38 AM

Hello, I've been reading a bit about the squirrel language and would like to make a script to change the display.
I've read documentation and there is a function called  "fe.set_display()"
If anyone could help me on writing a script to do so I'd greatly appreciate it.

fe.displays is an array containing a list of your displays, so you can check len() to see how many there are... each of those entries you can use .name to find out the name.

The issue I noticed when trying to use set_display is you will get stuck in a loop reloading the layout unless you check that you are loading a different display than is already loaded - here is two functions that load based on index or display name:

Code: [Select]

//find out about the displays
print(fe.displays.len() + " displays\n")
foreach(idx, display in fe.displays )
    print( idx + ": " + display.name + "\n")

//load based on display index
function load_display(idx) {
    if ( fe.list.display_index != idx ) fe.set_display(idx)
}

//load based on display name
function load_display_name(name) {
   foreach( idx, display in fe.displays )
      if ( name == fe.displays[idx].name && name != fe.displays[fe.list.display_index].name ) fe.set_display(idx)
}

load_display_name("mame")

Thanks for the help. One more thing. How would I go about running this script from the terminal to get the index and name of the displays?

You should just need to change AM to run in windowed mode and you can see the prompt output...

I'm sorry I thought I put that I was on a raspberry pi, running windowed doesnt change anything. I would jut like to run a script from terminal to get the display index or name, then another separate script to switch to said display from a terminal or ssh.

Well I would say it's better to design on something else and copy your layout over.. but I'm sure there is a way to pipe output to a logfile or launch it in another terminal and switch back and forth? My linux is a bit rusty.. regardless, unless you are running it in X it'll be a pain to see debug output and the UI
