profile-flame-graph

A library for providing Racket profiler outputs as flame graphs.

The library can optionally call out to the flamegraph.pl script. For this feature, you will need to check out the FlameGraph repo and add it to your PATH variable.

Quick usage

Install with:

raco pkg install profile-flame-graph

You will need to install FlameGraph. On a unix system, that might look like this:

git clone https://github.com/brendangregg/FlameGraph.git
export PATH="$PATH:$PWD/FlameGraph"

Add this import into the program you want to profile:

(require profile-flame-graph)

Wrap the expression you want to profile in your program like this:

(profile <your-code-here>
         #:svg-path "my-profile.svg"
         #:preview? #t)

and run your program:

racket <your-program>.rkt

which will write the profile output to my-profile.svg and pop up a window showing the flame graph.
