在MAXIMA中，我如何获得整个调用堆栈？

Question

对不起，如果这是一个新手问题，但我找不到任何文档或其他stackoverflow问题。我想查看在求解表达式或等式中调用的所有最大值函数的整个堆栈跟踪。我尝试了跟踪，回溯和调试模式。看着不同的显示和打印功能，但没有工作。

例1：

(%i1) is(equal((a+b)^2, a^2+b^2+2*a*b)); 
(%o1) true 

例2：

(%i2) trace(factor); 
(%o2) [factor] 
(%i3) trace_options(factor, info); 
(%o3) [info] 
(%i4) factor((x^2 - 7*x + 10)/(x - 5)); 
1 Enter ?factor [(x^2-7*x+10)/(x-5)] -> true 
1 Exit ?factor x-2 -> true 
(%o4) x-2 

我想看看每中间步骤千里马执行及其结果在这些溶液或conclusions.Info的推导上细微级调用甚至更好。

感谢， RB

正如你可以跟踪builtins-list.txt列出的所有功能，一个黑客：

l: read_list("builtins-list.txt") $ 
for e in l do errcatch(apply('trace, [e])) $ 
untrace(bfloatp) $ /* to limit output */ 
is(equal((a+b)^2, a^2+b^2+2*a*b)) $ 

回报：

(%i5) is(equal((a+b)^2, a^2+b^2+2*a*b)) $ 
          2 2 2 
1 Enter is [is(equal((a + b) , a + b + 2 a b))]
