Isolates: Calling functions in an isolate with an argument

[jwied]

I have a question about isolates and how to give an argument (a local variable) to a function, called in an isolate.

Here´s some code, I tried out:

iss←isolate.New¨'' '' '' ⍝ Make 3 isolates
t←iss.⎕DL 1 1 1 ⍝ Do 3 short delays
t←iss.(#.Version) ⍝ Call a niladic function Version
t←iss.(#.foo 99) ⍝ Call a monadic function foo with a

myLocVar←'abc' 'defg' 'hi' ⍝ simple argument for demo
iss.myVar←myLocVar ⍝ simple argument for demo
t←iss.(#.foo myVar) ⍝ works as expected
iss.(⎕ex'myVar')

⍝ Trying to call the monadic function "direct"
⍝ without defining and expunging variables in the isolates:
t←iss.(#.foo) myLocVar ⍝ FUTURE ERROR: 2: SYNTAX ERROR

What is the correct syntax for calling foo with the elements of myLocVar?

At the moment, you can only call functions which are in the isolate namespace. If you need to call a function which is in the root of the isolate process workspace, you need to make an indirect call via a function in the space. The easiest way to do this is to define a dfn on the fly, as in:

Code: Select all

iss.{#.foo ⍵} myVar

Thank you, Morten.
That solves my problem.
