## Code style Gist for [PR 1](https://github.com/bilderbuchi/openFrameworks/pull/1)

The `.patch` file below contains the necessary changes for making sure your PR conforms to the [OF code style](https://github.com/openframeworks/openFrameworks/wiki/oF-code-style).

### Usage
Download the patch file via the Download button on the left (to make sure all formatting is preserved). Apply the patch to the clean tip of your PR branch with `git apply --index --whitespace=nowarn <patchfile>`. The changes will land in your git staging area, ready to commit.

Before that, you can test if the patch succeeds with `git apply --index --whitespace=nowarn --check <patchfile>`

If you have problems, comment in the PR.
