What is Fluor ?
Fluor is a tool that allows you to automatically change the behavior of the keyboard's fn keys depending on the active application. It's that simple.
There's two main ways to install Fluor:
$ brew cask install fluor
You can also build it from source, but this is not recommended if your are only going to use Fluor in the regular way, and not hack it.
How does it work?
Fluor lies in your status bar and makes you see instantaneously which mode your keyboard is on:
This is what you get when you click on Fluor in the status bar:
You can choose the default mode. Whenever Fluor runs it will activate the default mode for your keyboard's fn keys.
You can also disable Fluor if you need to. It will set the keyboard's behaviour as it was prior to the application's launch.
This panel allows you to see all the rules you set at once. You can modify or delete any rule. Adding a rule will prompt a file selector in which you'll be able to select the application you want to set a rule for.
Sometimes it is not possible to select an application in the Rules Editor, especially for Steam games. This panel lets you set a rule for any running application. Of course the rules you set in this panel will be available directly in the Rules Editor. You can also remove a rule by setting the application behaviour to , it will also disappear from the Rules Editor panel.
Why is it open source ?
I made Fluor because I needed such an application. I wanted it simple, nicely designed and free and I didn't find such a thing on the internet. Once it was done I used it for a little while, cleaned up the code and decided to give it to others for free. What was a requirement for me can well be a requirement for others too.
You'd argue that such a non-sandboxed app had no chance to hit the AppStore and you'd be right. But if I had the chance it would have remained free and open-source. I don't think there's many people needing such an app and I prefer seeing it used by a wider range of people.
This app is also built using open-source code, that's why I think it belongs to this world. And if someone learns something looking at the code I'll be happy 😃.
All contributions are welcome. Fork it, hack it and make a pull request.
Fluor is released under the MIT license. See LICENSE for details.
Twice a month we will interview people behind open source businesses. We will talk about how they are building a business on top of open source projects.
We'll never share your email with anyone else.
