This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

visual-prof profiles your Haskell program and generates a html file containing its source code with parts of the code highlighted in different colors depending on the fraction of the running time that they take. visual-prof gives you an easy way to find places for optimization in your code.

Usage:

visual-prof -px A/B/C.hs run "arg1 arg2"

This will profile the C.hs file used by run.hs which contains the Main module of your project. Arguments to ./run are passed as shown (arg1, arg2,...). The parameters should be given in that order.

The simplest way to run it is:

visual-prof -px test.hs test

which will generate a profile for the file test.hs (which needs to have a main function)
