lbe, I am just looking at these modules right now. It is great that one can separate log output depending on categories but it seems to me that they don't actually catch print statements and redirect them but rather handle their own logger messages.

Ideally what I want is, given a perl program possibly using many modules, to run it and have every single print statement 1) redirected to file and 2) prepended by (filename,modulename,subname,linenumber). If I am given that program, it means I can clone it and replace all print statements with log statements but 1) what about print statements inside 3rd-party modules and 2) extra complication if bleached.

What I am doing right now and works is 1) redirect STDOUT to file 2) tie STDOUT to a class so when any print is called on that filehandle, I intercept the call and prepend the caller's fingerprint all the way to the top of the frame (<main>).

The module I mentioned works well but I had to extend it in order to handle STDERR and also for redirecting to a file (implementing OPEN/CLOSE).

In case you have a suggestion: my current problem is what data structure to use for storing all these print statements' output so that, for example, I make queries like: what is the STDOUT for lines X-Y, filename Z or do not show me output for lines so and so or sub so and so or package so and so. The data is all there but structuring it in order to make these queries is my next stop. I am currently playing with tree. I will sure post a separate request about these problems.

thanks, bliako
