5.4 How to display trace of a function as it runs in maple?

trace(foo); 
untrace(foo);
 

also see debug(foo);

Also

infolevel[all]:=5: 
printlevel:=10:
 

See http://www.mapleprimes.com/questions/35951-How-To-Debugtrace-Things-In-Maple

Also look at kernelopts(opaquemodules=true)

Here is a useful post by Carl Love from Maple prime forum that summarizes all of these

Here are four things that you can do to get more information. I have listed them in order by how structured the information is, with the most structured first.

1. Set

   infolevel[all]:= 5;
    
   

   That will cause programs to print out additional information of the programmers’ choosing. You can use higher or lower numbers for more or less information. Most programs don’t use levels higher than 5.

2. Print the code of procedures with showstat:

   showstat(int); 
   showstat(sin); 
   showstat(cos);
    
   

3. Trace the execution of particular procedures with trace:

   trace(int); 
   trace(sin);
    
   

4. Trace the execution of everything with printlevel:

   printlevel:= 10000:
    
   

   You can use higher or lower numbers for more or less information.
