Utils not accessible

Suppos the new module is called "mymodule", I added an Utils Object inheriting from mymodule root Obect, then added a function "testfunc".

Now when I try to call the function via $mymodule.Utils.testfunc, it complains Utils is not found. What change is needed to make Utils accessible?

Thank you.

Short answer:

Builder -- right-click the Utils object and choose “Add to Globals”

CSIDE -- type “Object Utils = mymodule::Utils” into file mymoduleGlobals.os

Long answer:

$mymodule is a variable that contains a reference to the mymoduleGlobals object in your ospace

$mymodule.Utils is (to be) a feature in the$mymodule object that contains a reference to the Utils object

The difference between how you define the feature and assign its value in the two IDE’s is because of what each IDE “knows” when you’re editing an ospace.

Builder knows about your Utils object, and so can provide a UI function to generate a reference to it.

CSIDE knows about your files and folders. By enforcing source files to have objects with the same name it allows for the construct “mymodule::Utils”. That represents a literal in the language, that can then be used in the code above to make up a compile-time assignment.

Hope this helps.

(Feel free to ignore the long answer. It’s there just in case you want to know “why”.)

Thank you very much.

Both mymodule::Utils.testfunc() and $mymodule.Utils.testfunc() after adding the definition into mymoduleglobal.os work. It's good to know the why.

It should be noted mymodule::Utils.testfunc() and $mymodule.Utils.testfunc() can point to two very different objects.

If you have done an OS.NewTemp() on mymodule::Utils and replaced the reference that is typically defined in the Globals then mymodule::Utils.testfunc() points to the original object reference and $mymodule.Utils.testfunc() will then point at the temp’ed reference.

For the most part, always referencing the $mymodule.Utils.testfunc() will be the safest. As it always been😊
