Pass data/values between two skill codes/allegro instances

There can be a couple of ways.

If you want to call another database, then yes for example
sh("allegro <board-name")
invokes another allegro as shown in the image below

The command line arguments of allegro are limited
allegro -product Allegro_performance board.brd -s script.scr -nograph

If you want to pass some other arguments, then you can do by writing a batch script, example test.scr
writing a bat file to call that script ex: myrun.bat file to call (allegro -s test.scr -product Allegro_performance -nographic unnamed.dra)
and calling bat file using sh("myrun.bat")

You can refer to the article provided in the below link for more information on scripts and how to run the script in a batch mode.

Hi, thanks for the reply, but this is not the issue... I can run the another alegro but let say in the first SKill code I have a variable x = list( "A" "B" C")

I will run the new instance of allegro with -s parameter that will run a script that will lunch a skill scrit an in than new one if I have print( x) it will be unbound variable error... The question is how to pass the x variable value from one skill to another (like share or at least copy the value)

Thanks,

There is a mechanism for this using mps.

Some code to help you going with this.

Skill code on the host side:  (after loading code call mps_startHost() )

/* HOST SIDE */
defun( mps_startHost ()
    defvar(_mpsExp nil)
  _mpsExp = mpsExport("Host123" "remoteSkill" "v1" list('mps_HostFunction1 'mps_HostFunction2))
  ;mpsClose(_mpsExp)
);defun

defun( mps_closeHost ()
    mpsClose(_mpsExp)
)

defun( mps_HostFunction1 (data)
    axlMsgPut( "mps_HostFunction1 %L " data)
    "return 1"
)

defun( mps_HostFunction2 (data)
    axlMsgPut( "mps_HostFunction2 %L " data)
    "return 2"
)

client side skill code:   (after loading call mps_startClient() )

/* CLIENT SIDE */
defun( mps_startClient ()
    let( ()
    _mpsImp = mpsImport("Host123" "remoteSkill" "v1" )
    ;_mpsImp->??
 
));defun

Now at the client side you can call the host function like this:
_mpsImp->mps_HostFunction1("test1")

This call will result in "return1".  This is the value returned by the function on the HOST.
On the host side you will see "test1", this is the value send from the CLIENT

Look at the 'Distributed SKILL' for more information about these functions.

Hi B Bruekers,

Thanks a lot. I'm looking into the Distributed SKILL but the documentation is relatively "sparse"... however, I have been able to run/modify your code, but I have a few questions.

The example you shared:

- first code creates "server"

- define two functions that can be executed remotely from the second code but they will be executed in the first code

My question is - how I can transfer some "data/values" from the first code to the second code?

the first code will create a list of let's say jedec_names and I want to send them to the second code (this I don't understand how to do)

the second code once received will check some stuff and then send it back (this part is in your example - I mean I can pass them to some function in the first code as input)

Thanks!

Hi, I'm stupid :) the "return1" will be the data I need to get. I need to test it but I think it will be OK (it was 00:15 am) when I waited the previous reply :D
