Fenrir

A TTY screenreader for Linux. In theory it's not just limited to Linux. but i currently only provide drivers for that since I do not have another system here. If you want to help or write drivers to make it work on other systems, just let me know. This software is licensed under the LGPL v3 .

Requirements (core)

• linux (currently only screen and input drivers available for that)
• python3 >= 3.3
• python-configargparse
• screen, input, speech, sound or braille drivers see "Features, Drivers, Extras".

installation

• Archlinux: PKGBUILD in AUR
• Manual: run install.sh and uninstall.sh as root
• you also can just run it from Git without installing: You can just run the following as root: if you are in Fenrir Git rootfolder: cd src/fenrir/ sudo ./fenrir Settings "settings.conf" is located in the "config" directory or after installation in /etc/fenrir/settings. Take care that the used drivers in the config matching your installed drivers. By default it uses:
• sound driver: genericDriver (via sox, could configured in settings.conf)
• speech driver: speechdDriver
• braille driver: brlttyDriver (WIP)
• input driver: evdevDriver
