Program to fold GHC prof files into flamegraph input The reasons why this package exists despite other packages with similar functionality (not including the NIH syndrome) boil down to: it does only one thing (stack collapsing), so it's up to the user to install flamegraph scripts, pass options etc (in my eyes it's not a limitation, on the contrary), output control: annotations (color profiles), extending traces from a configured set of modules with the source locations or toggling qualified names, precise ticks and/or bytes with -p reports, it's fast If you have a detailed prof file (-P RTS option) If you have a standard prof file (-p RTS option) If you have a detailed prof file (-P RTS option) If you have a standard prof file (-p RTS option) See the full README for details.
