Fun project I am working on

[Daestrum]

I have currently got working, the ability to inline java into B4J not like #If JAVA ...#End If, but inside a sub if needed. It's still rough at present, but a few sneak views of what it looks like.

Sub listSort(mylist As List)
    java("_mylist.getObject().sort((a, b) -> ((Comparable)a).compareTo(b))")
    java("System.out.println(@@Class: @@ + _mylist.getClass())")
    java("for (Field f : _mylist.getClass().getDeclaredFields()) System.out.println(@@Declared: @@ + f)")
    java("for (Field f : _mylist.getClass().getFields()) System.out.println(@@Public: @@ + f)")
    java("for (Field f : _mylist.getClass().getSuperclass().getDeclaredFields()) System.out.println(@@Super: @@ + f)")
End Sub

(in the above read @@ as ")

public String  _listsort(anywheresoftware.b4a.objects.collections.List _mylist) throws Exception{
 //BA.debugLineNum = 13;BA.debugLine="Sub listSort(mylist As List)";
 //BA.debugLineNum = 14;BA.debugLine="java(\"_mylist.getObject().sort((a, b) -> ((Compar";
_mylist.getObject().sort((a, b) -> ((Comparable)a).compareTo(b));
 //BA.debugLineNum = 15;BA.debugLine="java(\"System.out.println("Class: " + _mylist.ge";
System.out.println("Class: " + _mylist.getClass());
 //BA.debugLineNum = 16;BA.debugLine="java(\"for (Field f : _mylist.getClass().getDeclar";
for (Field f : _mylist.getClass().getDeclaredFields()) System.out.println("Declared: " + f);
 //BA.debugLineNum = 17;BA.debugLine="java(\"for (Field f : _mylist.getClass().getFields";
for (Field f : _mylist.getClass().getFields()) System.out.println("Public: " + f);
 //BA.debugLineNum = 18;BA.debugLine="java(\"for (Field f : _mylist.getClass().getSuperc";
for (Field f : _mylist.getClass().getSuperclass().getDeclaredFields()) System.out.println("Super: " + f);
 //BA.debugLineNum = 19;BA.debugLine="End Sub";
return "";
}

Just a fun project as it allows java access to local variables inside subs.

Currently working on release , but doesnt break debug, just ignores the java inserts.

Got two ways for the code now, single lines like in above example, and now got multiline working too (still in release not debug yet)

    javam($"Integer a = 10;
for (int b=0; b<a;b++){
    System.out.println(b);
}"$)

creates this java

 //BA.debugLineNum = 24;BA.debugLine="javam($\"Integer a = 10; for (int b=0; b<a;b++){";
Integer a = 10;
for (int b=0; b<a;b++){
    System.out.println(b);
}

Only side effect - b4j error line numbers get a bit skewed from the added java code.
