#Fafi Browser

Fafi is a Gemini browser written in Racket. It is early days for this code base and there is much work to be done. At the moment the happy path for loading text/gemini and text/plain is working but I still need to implement the handling of the other status codes and mime types. This begun as just an experiment to calm me during my free hours, now I want to make it into a real gemini browser.

#What is gemini protocol?

It is a new protocol that is simple to implement and focused on privacy and low-resource usage. It is somewhere between gopher and the web. You can learn more about it in gemini.circumlunar.space — this is a proxy link

#Running

On your terminal:

Install the needed dependencies with:

$ raco pkg install

fafi needs the following packages:

• markdown
• xexpr-path

You can continue without the step above if you already have them installed.

$ racket main.rkt

If you want to open an specific capsule:

$ racket main.rkt gemini://port1965.eu

Or run main.rkt on DrRacket.

#Building

If you want a standalone version of Fafi browser you can build it with:

$ racket build.rkt

That will create a dist/ folder and place a distributable version of Fafi inside it. It will also create a single packaged file at the repository root folder that you can distribute to your friends. This file is either a .dmg on macOS, a .zip in Windows, or a .tar.gz in UNIX-like OS.

#Keyboard & Mouse shortcuts

• F5: reload
• Home: go to homepage.
• alt+left: go back.
• alt+right: go forward.
• ctrl+w: close tab.
• ctrl+t: new tab.
• ctrl+q: quit.
• middle-button click: opens link in a new tab.
• ctrl+h: opens history queue.

#History management

Be aware that Fafi uses a single queue for history management. This means that all the tabs are a part of the same queue regardless if you navigated to that capsule as a new tab or in the same tab. This is different than major web browsers which usually use a per-tab history queue. Fafi approach is simpler but it is different than what you are probably used to. The history is erased when the app quits.

To view your history queue select the View → History menu.
