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.

This is a small tool to convert ghc `.prof` files into a format consumable by FlameGraph.

Obtain `.prof` files by compiling with `--enable-profiling` and running with `+RTS -P -RTS`.

$ cat app.prof |
  prof-flamegraph |

This is a fork of https://github.com/fpco/ghc-prof-flamegraph which hides the intermediate flamegraph format.
