...ernally. It seems a shame to allow a big usability issue for `do.call` to remain when there is a simple solution at hand, especially since the complete deparse of large objects likely serves no purpose in this case. Obviously, if storing the actual calls instead of their deparsed equivalents in .Traceback causes problems I'm not anticipating, then that's different.? Is that the case? Best, Brodie.

We also have a few other suggestions and wishes about backtrace storage and display on the one hand, and display of constructed calls on the other hand. Perhaps it would be better to open a different wishlist item for traceback() to keep the discussions focused? FWIW I think deparsing backtraces lazily is a great idea. Displaying 1 line per call by default in interactive sessions, while being able to get a more exhaustive output by calling `traceback(max.lines = Inf)`, offers the best of both worlds. Understanding the st...

...etailed progress to log file and conditions (warnings and errors) are written to the same log file immediately by using withCallingHandlers(..., condition=function(c) cat(c, file=logFile)). However, I would also like to write the call stack to the log file to further simplify troubleshooting; traceback() does unfortunately not work here. From ?traceback, we have "Errors which are caught _via_ 'try' or 'tryCatch' do not generate a traceback, so what is printed is the call sequence for the last uncaught error, and not necessarily the last error." (and it seems to be...

The tracebacks are compressed into a single line because we're using PyObject_Str, but they are just about usable if not very readable. For example you would see an error like this: nbdkit: error: ./python-exception.py: config_complete: error: ['Traceback (most recent call last):\n', ' File &qu...

Dear R experts---I may have asked this in the past, but I don't think I figured out how to do this. I would like to execute traceback() automatically if my R program dies---every R programI ever invoke. I guessed that I could have wrapped my entire R code into tryCatch( ... oodles of R code , error = function(e) traceback(), finally = cat("done") } but the traceback docs tell me that this does not generate a traceb...

Hi! Is there a way to write the information stored in the .Traceback variable to a file? When I try it with dump() ".Traceback" <- list("dump(.Traceback, file = \"Mytraceback.R\")") Or there are other ways to write this information on the disk if an error occurs? Eryk

Hi, in R-3.1.0 (Linux), traceback() does not show the source file line number for the truncated calls, when limiting the number of lines output for each call with argument max.lines. See sample code, output and session info below (in particular, output for call number 5). I guess this is not intended. Thank you. Bests, Renaud ##...

We used traceback.format_exception, returning traceback lines. Join the lines to make the tracebacks more readable. Here is an example traceback: $ ./nbdkit -f -v python tests/python-exception.py ... nbdkit: debug: python: config_complete nbdkit: error: tests/python-exception.py: config_complete: error: Traceback...

I would like to have an automatic traceback printed on error. Is there a way to do this? options(error=traceback) seems to print the previous error, not the current error. I'm guessing this is because the traceback is not set until the error handler is done running. > options(error=traceback) > stop("1") Error: 1 No tra...

Has something changed with traceback's in R-patched? When I running the examples for ?traceback, I get > foo <- function(x) { print(1); bar(2) } > bar <- function(x) { x + a.variable.which.does.not.exist } > foo(2) # gives a strange error [1] 1 Error in bar(2) : Object "a.variable.which.does.no...

The addition of `.traceback` in r70207 adds one more function to the call stack when invoking `traceback()`.? This changes the output of one of the examples to include the error handler call: > options(error = function() traceback(2)) > foo(2) [1] 1 Error in bar(2) : object 'a.variable.which.does.not.exist' no...

Hi, I wonder how to have R automatically print stack trace produced by traceback upon errors during interactive uses. I tried the suggestions on http://old.nabble.com/Automatically-execute-traceback-when-execution-of-script-causes-error--td22368483.html#a22368775 and used options(error = recover) options(showErrorCalls = T) It just produces an extra message like "recover...
