- I finally got sick of showstack and baktrace and rewrote them in lisp,
- rincorporating some of the features people have been requesting.
- Showstack now works as follows:
- (showstack) : show all interesting forms. Forms resulting from
- the trace package are not printed as well as
- extraneous calls to eval. In the form printed,
- the special form <**> means 'the previous expression
- printed'. prinlevel and prinlength are set to
- reasonable values to prevent the expression from
- getting too large
- (showstack t) : same as above but print all expressions.
- (showstack 5) : print only the first 5 expressions. of course, 5
- is not the only possible numeric argument.
- (showstack lev 3) : set prinlevel to 3 before printing
- (showstack len 4) : set prinlength to 4 before printing
- the above arguments can be used in combination.
-
- The default value of prinlevel is showstack-prinlevel, that of prinlength
- is showstack-prinlength. the default showstack printer is the
- value of showstack-printer (default is 'print').
-
- baktrace accepts the same arguments as showstack, but it ignores the
- prinlevel and prinlength arguments.
