# profile-flame-graph
[](http://docs.racket-lang.org/profile-flame-graph/index.html)
A library for providing Racket profiler outputs as
[flame graphs](https://github.com/brendangregg/FlameGraph).
The library can optionally call out to the `flamegraph.pl` script.
For this feature, you will need to check out the
[FlameGraph](https://github.com/brendangregg/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:
```racket
(profile
#:svg-path "my-profile.svg"
#:preview? #t)
```
and run your program:
```
racket .rkt
```
which will write the profile output to `my-profile.svg` and pop
up a window showing the flame graph.
