B4J Question [Solved] Library Debug vs Release

[Daestrum]

Is there a simple way for a library to check if it is being run against a debug (IDE) run version of an app or a release version (ie java -jar xxx).

The reason I ask is I have noticed the method signatures vary in a Class module depending on release or debug (extra parameter in debug).

Sorted - completely forgot about #if DEBUG

Sorry...

Not sorted, I need to know if app is running from IDE or jar file.

#CommandLineArgs: inide

Sub AppStart(Args() As String)
   If Args(0)=="inide" Then
.....

#CommandLineArgs: inide

Sub AppStart(Args() As String)
   If Args(0)=="inide" Then
.....

Running the jar the project crashes (and not for the little mistake about the double equal sign, corrected, of course)

 

[Roycefer]

The double equal sign isn't a mistake. Quite the contrary, not using it is a mistake.

It crashes because there is no bounds checking. Shall I demonstrate that for you?

 

[LucaMs]

As far as I know it does not work in b4x (although I have not tried)

 

[Daestrum]

That works for what I want.
I used

'set debugging flag in class module
ocm.debugging = Args(0)="inide"

 

[Erel]

ocm.debugging = Args.Length > 0 AND Args(0) = "inide"

Thanks for the suggestions, eventually I had to go a different code route as there were differences between release and debug in the IDE runs.

In case anyone else needs to call a b4j Class module sub from a java library I found the simplest way was to add a dummy sub to the class module.

Public Sub semaphore() ' Dummy method
End Sub

I then just check the number of parameters it expects, if none , then I call other subs as normal. If it needs 1 parameter I call them with the class instance as the first parameter.

Why not raise an event with BA.raiseEvent? This is the correct way to call a B4X sub.

 

[Daestrum]

It was more a case of 'Can I?" as opposed to "Should I?".

I sometimes use more than one instance of a code module and needed a way to call a sub in a particular instance (not a problem with a Class module).

 

[Erel]

I sometimes use more than one instance of a code module

It is not possible to create more than one instance of a static code module. Static code modules = singletons.

 

[Daestrum]

I just initialize a new instance.
That way a thread has its own copy to use.

(othercodemodule) b4j.example.othercodemodule@29a2db4d
(othercodemodule) b4j.example.othercodemodule@673c97ed

This cannot be done from B4J and is a mistake to do if it is done in your Java code. Use classes instead.
