Friendly-traceback and IPython: update
In my previous post, I mentioned that, unlike IPython, friendly/friendly-traceback included values of relevant objects in a traceback. As I wrote in the update, Alex Hall pointed out that one could get this information by using a verbose mode in IPython. Here is the previous example when using the verbose mode.
In (1) I enabled the verbose mode. In (3), we see its effect. (2) is a reminder of the highlighting when it spans many lines. Regarding the highlighting, here's what I had in the previous blog post:Alex Hall (yes, him again), the author of stack_data used by both IPython and friendly-traceback, suggested that perhaps a better way would be to have a common indentation. This is what I implemented next:
In my code, this is done in a rather convoluted way. Following a suggestion by Alex, I implemented a change in stack_data itself which yields the correct result, at least when using carets (^) as marker for the location. If Alex can confirm that it works for stack_data in all cases, this new way of highlighting consecutive lines would likely be automatically incorporated into IPython.
The reason I go into all these datails is as follows: I'm really interested in getting feedback from users so as to make friendly/friendly-traceback even more useful. So, don't be shy! :-)
