在 MAXIMA 中，如何打印整个调用堆栈？

Question

抱歉，如果这是一个新手问题，但我找不到关于此的任何文档或其他 Whosebug 问题。我想查看在求解表达式或方程时调用的所有最大值函数的完整堆栈跟踪。我尝试了跟踪、回溯和调试模式。查看了不同的显示和打印功能，但 none 有效。

示例 1：

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

示例 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

我希望看到 Maxima 执行的每个中间步骤及其推导这些解决方案的结果或 conclusions.Info 在最小级别的调用中甚至更好。

谢谢， RB

作为 hack，您可以跟踪 builtins-list.txt:

中列出的所有函数

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 )) $

returns:

(%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))]
 1 Enter ratp [2]
