Re: clojure.stacktrace/root-cause VS clojure.repl/root-cause, are they redundant?
They're just different versions of the same thing, written at different times by different people, that both got merged into Clojure at different times. Speaking as the original author of clojure.stacktrace, I now think neither one of them should exist. The .printStackTrace method on an exception gives you all the same information and is more reliable. -S On Monday, July 21, 2014 7:30:17 AM UTC-4, Pierre Masci wrote: Hi, I'm learning about tools to help me debug from the REPL, and I found these two with the same name: clojure.stacktrace/root-cause clojure.repl/root-cause -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: clojure.stacktrace/root-cause VS clojure.repl/root-cause, are they redundant?
Thank you Stuart, this is a very useful answer. Is there any way to access an exception older than *e? What happens to me regularly is to mistype (.printStackTrace *e), which makes me lost my previous exception. -- Pierre Masci On 24 July 2014 13:33, Stuart Sierra the.stuart.sie...@gmail.com wrote: They're just different versions of the same thing, written at different times by different people, that both got merged into Clojure at different times.

Re: clojure.stacktrace/root-cause VS clojure.repl/root-cause, are they redundant?
I know of no way that older exceptions than *e are automatically saved anywhere (unlike the results of previous REPL expressions, of which the last 3 are saved in *1 *2 *3). When an exception occurs, it is probably much less error-prone to type a short expression like (def e1 *e) to save the exception in e1, even if another exception occurs after that which modifies *e.

Saving *e in a def for further investigation, handy :) Cheers On 24 Jul 2014 15:48, Andy Fingerhut andy.finger...@gmail.com wrote: I know of no way that older exceptions than *e are automatically saved anywhere (unlike the results of previous REPL expressions, of which the last 3 are saved in *1 *2 *3).

clojure.stacktrace/root-cause VS clojure.repl/root-cause, are they redundant?
Hi, I'm learning about tools to help me debug from the REPL, and I found these two with the same name: clojure.stacktrace/root-cause clojure.repl/root-cause For a very simple case (wrong arity), they give pretty similar output: user= (char 0 0 0) CompilerException clojure.lang.ArityException: Wrong number of args (3) passed to: core/char--inliner, compiling:(/tmp/form-init6819528724684564936.clj:1:1) user= (clojure.stacktrace/root-cause *e) #ArityException clojure.lang.ArityException: Wrong number of args (3) passed to: core/char--inliner user= (clojure.repl/root-cause *e) #CompilerException clojure.lang.ArityException: Wrong number of args (3) passed to: core/char--inliner, compiling:(/tmp/form-init6819528724684564936.clj:1:1) I looked at the source code and they look fairly similar, but I didn't understand the exact details. If they do the same job, then which one does it best? If they perform different roles, then could you describe the difference to a user who doesn't need to understand the internals?
