Personally, I'd just grab the file names, line numbers, and function names for the bottom 10 stack frames and do zero formatting. Just stuff those into a simple array. You can format those later only if the information needs to be shown. You can likely format the information better than Carp does because you know your specifics. For example, I don't want full paths for every single source file at work because most of them are going to start with /site/ourcorp/myproduct/version/lib/FOO, a long value whose repetition just makes it harder to read the useful information. I also don't want to see the attempts at abbreviating which arguments got passed to each function. If I really need that level of detail, then I'm going to build my own way of declaring "this is what is interesting about this particular call to this function" rather than hoping that an extremely terse summary of the top-level structure of each argument is even moderately informative. I would hope that such would be less of a performance impact than what Carp does. But I have not measured the difference. It might still be too slow for your case. - tye In reply to Re: lightweight stack info (data > text)
