Fenrir User Manual
Fenrir is a modern command line screen reader written in Python3.
It has a modular structure, a flexible based driver model, is highly configurable and easy
to customize and extend (see Developer Manual (fenrir_development_manual)).
Please see the following pages for the current (fenrir_current_version) and Git
(fenrir_git_version) version of Fenrir.
Support and Requirements
Fenrir requires several drivers to interact with the operating system.
Speech Drivers
A speech driver is for communication with the text to speech system like Speech-Dispatcher
(#SpeechDispatcher) or Espeak (http://espeak.sourceforge.net). \ See section Speech
(#Speech) in ''settings.conf'' for more information.
SpeechDispatcher
This driver is used by default. It uses Speech-dispatcher as its backend.
Dependencies:
• Speech-dispatcher (installed and configured, Documentation
(https///devel.freebsoft.org/speechd#sec2))
• Python-speechd
Espeak
Uses Espeak via Python bindings.
Dependencies:
• Espeak or Espeak-ng
• python-espeak (https///launchpad.net/python-espeak)
Generic
This invokes speech via a sub-process. This is almost the same as using the commandline.
The performance depends on the overhead of the speech synthesis application but it is
really flexible.
Dependencies:
• Espeak or Espeak-ng
The Requirements are flexible, they depend on the configuration in settings.conf.
Dummy
this is just for debugging, logs are output to the screen and logged as well.
Sound Drivers
To play sound icons and similar.\ See section Sound (#Sound) in ''settings.conf'' for more
information.
Generic
This driver is used by default.
Dependencies:
• Sox (http://sox.sourceforge.net/) with opus support The Requirements are flexible, they
depend on the configuration in settings.conf.
Gstreamer
if you prefer to use Gstreamer for sound output.
Dependencies:
• Gstreamer >= 1.x
• Glibc
Dummy
this is just for debugging, logs are output to the screen and logged as well.
Input Drivers
Input drivers are to capture keyboard shortcuts issued to the screen reader
See section Keyboard (#Keyboard) in ''settings.conf'' for more information.
Evdev
This driver is used by default.
Evdev is the low level input device framework for Linux.
Dependencies:
• python-evdev >=0.6.3
• pyudev
• loaded uinput kernel module
• exclusive access to the input devices Read permission to the following files and
services:
• /dev/input
• /dev/uinput
Screen Drivers
The job of a screen driver is to get the information of current screen content.\ See
section Screen (#Screen) in ''settings.conf'' for more information.
VCSA
This driver is used by default. For Linux VCSA devices. These exist on any current
standard installation of Linux.
Dependencie s:
• python-dbus Read permission to the following files and services (or run as root):
• /sys/devices/virtual/tty/tty0/active
• /dev/tty[1 - 64]
• /dev/vcsa[1 - 64] (VCSA manpage (https///linux.die.net/man/4/vcsa))
• read Logind DBUS
Braille Drivers
This is for Braille support. Braille is currently a work in progress and is planned for
the Fenrir 2.0 release.\ See section Braille (#Braille) in ''settings.conf'' for more
information.
BRLTTY
This driver is used by default. It uses BrlTTY (brltty) to communicate with with a
Braille device.
Dependencies:
• BrlTTY (configured and running, Documentation (http://mielke.cc/brltty/doc/Manual-
BRLTTY/English/BRLTTY.html))
• python-brlapi (configured, Documentation (http://mielke.cc/brltty/doc/Manual-
BrlAPI/English/BrlAPI.html)) ## Currently supported platforms
Currently Fenrir completely supports the following Platforms:
• Linux TTY Support for further Systems are planned.
Installation
Fenrir can run without installation. It just requires the dependencies are installed
first.
We recommend to try it out before installation to be sure everything works and prevent
yourself from experiencing a non-talking environment.
Try Out
Fenrir does not require installation. You can try it and make sure everything works
before you decide to install. In this way you can be sure that your system doesnt break
or stop talking. for that you can just grab the code and run as root
''src/fenrir/fenrir'' (in foreground) or ''src/fenrir/fenrir-daemon'' (in background, used
by systemd for autostart)
Install it
Documented operating systems
Arch Linux
For Arch there are PKGBUILDs in the AUR:
• fenrir (https///aur.archlinux.org/packages/fenrir/)
• fenrir-git (https///aur.archlinux.org/packages/fenrir-git/)
Manual
1. Download the latest stable version from the Fenrir-Project (https///linux-
a11y.org/index.php?page=fenrir-screenreader) site.
2. Unpack the archive
3. Check the needed Dependencys by running check-dependencys.py
(https///github.com/chrys87/fenrir/blob/master/check-dependencies.py) script
4. install the missing dependencies an standard installation requires the following:
• python3 >= 3.3 (and all the following is needed for python3 )
• python3-speechd (screen)
• python3-dbus (screen)
• python3-evdev >= 0.6.4(input)
• python3-daemonize (background service)
• python3-brlapi (braille)
• python3-pyenchant (spellchecker)
• your language for aspell (aspell-<lang>) (spellchecker)
• sox (sound)
• For an individual installation see Support and Requirements (#Support and
Requirements) or consult the Readme
(https///github.com/chrys87/fenrir/blob/master/README.md))
5. run "install.sh" as root
this installs Fenrir as the following
* Application:''/opt/fenrir''
* Settings:''/etc/fenrir''
* Sound Icons:''/usr/share/fenrirscreenreader/''
to remove Fenrir just run uninstall.sh as root
Git
if you want to get the latest code you can use git to get a development snapshot:

Features
Commands
Keybindings
Normal commands can be invoked in two ways: 1. Using a Metakey (FenrirKey (#Fenrir Key))
2. Shortcuts with a single key
See section Keyboard (#Keyboard) in ''settings.conf'' for more information. #### Fenrir
Key
The Fenrir Key is for invoking screen reader commands. Fenrir can utilize more than one
FenrirKey at the same time. By default the following keys are used: 1. Insert 2. KeyPad
Insert 3. Meta (Super, Windows)
Script Key
To invoke "Scripts" the Script Key is mandatory. The shortcut is encoded in the filename
of the script. See Scripting (#Scripting) #### Desktop Layout

Interrupt the current spoken. ### Review Modes
Fenrir provides a virtual cursor, with it you can navigate all over the screen without
changing the text cursor.
Using the review feature will open the review mode automatically.
The review cursor always starts from the text cursor. Attention: after using the review
mode, the review cursor will stay open until you use the ''exit review'' shortcut.
Think when using clipboard operations and similar. The review cursor is always prefered
over the text cursor.
Fenrir sounds a bell sound if the used review command jumps to another line or end of
screen. #### exit review

### Handling marking
A mark defines a point of origin or end to prepare to copy or paste a block of text. \
Examples where you need marks are:
• copy to clipboard
• set window application
• set bookmark 1 - X #### Set mark
How to set a mark: 1. navigate with review or textcursor to the position you want to set
the mark. Attention: if a review cursor is set, that is the prefered. If you want to use
text cursor, be sure that you are not in review mode. 2. press shortcut for ''set mark''
you can set two marks (begin and end). Some commands allow some simpler usecases just
using the whole line if only one mark is set. you may want to try this out. #### Get
text between marks
To get the text that is currently between your marks press shortcut for ''marked text''.\
#### Remove Marks
You can remove all current marks by pressing the shortcut for ''remove marks''. Changing
the screen also removes the marks. ### Screen Interaction
Fenrir provides several methods to interact with the current screen. #### forward
keypress
This just forwards the next shortcut to the screen Fenrir shortcut or not. This is useful
if the currently pressed shortcut is also in use by Fenrir. #### Clipboard
Fenrir provides a clipboard with multible items represented by a list. You navigate
throught the list and paste the selected clipboard. ##### copy marked to clipboard
To copy something to the clipboard you need to set one or two marks. if you set one mark,
the text between the mark and your current cursor is copied to clipboard. Setting two
marks just copies the text between the marks into the clipboard. If you copy something it
is always placed as the first item on your clipboard. ##### clear clipboard
You can remove all items from the current clipboard by ''clear clipboard'' functionality.
##### first clipboard

Different types of tracking are currently supported See section Focus (#Focus) in
''settings.conf'' for more information. #### Cursor Tracking
This follows the text cursor. This is the typical way an application works. This is used
by:
• almost any shell such as (Bash, Zsh, sh)
• vim
• nano
• emacs
• mutt
• tintin++ #### Highlight Tracking
In some applications there are no text cursors. In those applications cursor changes are
represented by different colors or attributes (underlined or bold). This mode tracks and
announces these changes for you. This is used by:
* wifi-menu
* dialog
* alpine
Tutorial Mode
Fenrir provides a Tutorial mode. When you enter tutorial mode, screen reader commands are
intercepted and explained instead of executing them. ''Arrow up'' and ''Arrow Down'' let
you navigate through a list of all available commands with shortcuts and description.
Pressing escape leaves the tutorial mode.
Information
Time
Announces the current Time. #### Date
Announces the current Date. #### Bookmarks
Bookmarks provide quick access to part of the screen without the need to navigate to the
area. By default Fenrir provides 10 bookmarks. Those can be set and accessed via
shortcut. This is useful for status lines or other information where the position does
not change. ##### set Bookmark X
You need to set the bookmark first. For that you have to set one or two lines for use.
1. Set marks (one or two) 2. press shortcut for ''set bookmark X''. X represents the
number 1 - 10. ##### read Bookmark X
If a bookmark is set you can access the area just by pressing the ''bookmark X'' shortcut.
X represents the number 1 - 10. Bookmarks are dynamic. That means the content changes
with the screen. ##### clear Bookmark X
to remove a bookmark just press the ''clear bookmark X'' shortcut. X represents the
number 1 - 10. Afterward the bookmark is no longer available. #### cursor position
You can get information about the current cursor and its position by using the "cursor
position" functionality. #### indent current line
Announce the current indent level of the current line. It represents the number of
trailing spaces of the line. #### current screen
Reads all the current screen from the beginning to the end. #### current screen before
cursor
Reads current screen from the beginning of the screen to the current cursor position.
#### current screen after cursor
Read anything after current cursor position to the end. #### cursor read to end of line
Read from the current cursor position to the end of the current line. #### cursor column
Read the current X position of a cursor (column of the current line). #### cursor line
number
Read the current Y position of a cursor (line number). #### present first line
Reads just the first line. this is maybe useful for status information. #### present
last line
Presets the last line. This is maybe useful for status information. #### last incoming
Repeat the last automatically incoming text. ## Input
Echo
Fenrir provides different methods of echoing content:
• Word: Will speak each word after you push space
• Character: speak any letter you type on the screen
• Delete Character: speaks the character prior to the cursor when you push backspace ###
Silence on Key press
Spellchecker
Fenrir has a built-in spellchecker, it can invoke automatically while typing or be called
by a shortcut. Commands to add or remove the current word to the dictionary are included.
As using the spellchecker is enhanced usage. You will need dictionary aspell-<language>.
See section General (#General) in ''settings.conf'' for more information. #### spell
check
Invokes the spellcheck on the word that contains the Review or text cursor. #### add word
to spell check
Adds the word under the Review or Text cursor to the dictionary. #### removes word from
spell check
Removes the word under the Review or Text cursor from the dictionary. ## Announcements
Emoticons
If you want to replace ":)" emoticons with "smile" in speech you can use this feature. It
can be toggled on or off. You can define emoticons in a dictionary, please see Emoticon
Dictionary. See section General (#General) in ''settings.conf'' to see how to enable or
disable this feature.
Time
Announce the time at periodical increments, To track the time easily. You can define 2
different ways of time announcements. 1. periodic 2. on fix minutes
Example periodic, every 20 minutes "delaySec=20":
[time]
enabled=True
presentTime=True
presentDate=True
delaySec=20
onMinutes=
announce=True
interrupt=False
Example on fix minutes in an hour. example every quarter "delaySec=0" and
"onMinutes=00,15,30,45":
[time]
enabled=True
presentTime=True
presentDate=True
#delaySec is repected bevore onMinutes so it need to be set to 0
delaySec=0
onMinutes=00,15,30,45
announce=True
interrupt=False
Promoted List
Promoted Lists are a nice feature if you are away from your computer or performing more
longer tasks. you can define a list of words which you want to hear a sound icon for
after a period of inactivity. Example if the word "Chrys" appears after 120 Seconds of
inactivity: [promote] enabled=True
inactiveTimeoutSec=120 list=Chrys See section Promote (#Promote) in ''settings.conf'' for
more information. ### Punctuation
Fenrir handles punctuation levels and names for you with several provided dictionaries.
See levelDict See punctuationDict ## Braille
Fenrir provides Braille support in Version >= 2.0. See section Braille (#Braille) in
''settings.conf'' for more information. ### braille flush
If a message appears on the Braille device you can flush it to get back to the review- or
system cursor ### Braille pan left
If a line is longer than your Braille devices you can move the view (called panning) to
the left. So you can read stuff without the need to move the review- or system cursor.
### Braille pan right
If a line is longer than your Braille devices you can move the view (called panning) to
the right. So you can read stuff without the need to move the review- or system cursor.
### braille return to cursor
When you have finished reading the line on the Braille device using panning, the focus can
be returned to the current used cursor by using "return to cursor" command. ## Dictionary
You can make use of different kinds of built-in dictionary's. A dictionary has a name and
list of keys and values separated by :===: Example: [customDict] Chrys:===:Chrys is cool
lollipop:===:lolli that means that every instance "chrys" is displayed, speech will say
Chrys is cool. "lollipop" is spoken as "lolli". Before making changes to a dictionary we
recommend making a backup of your current dictionary in case future updates overwrite your
local changes. ### Punctuation
Level
The punctuation level dict contains lists with "what punctuation is spoken in what level".
the default one looks like this: [levelDict] none:===: some:===:.-$~+*-/\@
most:===:.,:-$~+*-/@!#%^&()[]}{<>; all:===:!"#$%& '()+,-./:;<=>?@[\]^_`{|}~ the level
"none" has no values. so it should not speak any punctuation (sadly this is not respected
by every TTS system) if "some" is the current level the following are spoken: dot dash
dollar tilde plus star slash backslash at. same for most and all, you can add new levels.
if you cycle punctuation levels they are recognized. the default punctuation level is set
in settings.conf. The default is "some". #### Punctuation
The punctuation dictionary "[punctDict]" contains how the punctuation is spoken. Example:
[punctDict] :===:line
speaks an as "line".
[punctDict] :===:underscore speaks an as underscore. for question mark an ? is appended
to the word that the TTS system can announce the question correctly.
### Custom
The dict "[customDict]" is just for your own use, it just replace the key with the value
without any special functionality. This might be used to fix incorrectly spoken words,
make words more common, shorter or just for fun. :) ### Emoticons
The Emoticons dictionary "[emoticonDict]" by default contains some emoticons. it can
replace ":)" with "smile" or "XD" with "loool" Making chat more colorful. A nice feature
with this dictionary is that you can toggle the substitution on or off during run time or
in settings.conf. This is useful because while doing programming or other serious work
you want to hear colons and perryns not smiles. # Configuration
You can configure Fenrir in the following places (ordered by priority): 1. Commandline
Parameters ''-o'' see Set settings coption (#Set settings coption) 2.
/etc/fenrir/settings/settings.conf see Settigns (#Settings) 3.
<sourceTree>/config/settings/settings.conf see Settigns (#Settings) 4. hard coded
defaults ## Commandline Arguments
Set settings option
You can specify options that overwrite the setting.conf. This is done with ''-o
<list of options> parameter. The list of options have the following syntax fenrir -o
"section#setting=value;section#setting=value"
For example changing the sound driver to gstreamer and disabling Braille
fenrir -o "sound#driver=gstreamerDriver;braille#enabled=False=False" or change the debug
level to verbose fenrir -o "general#debugLevel=3" You can find the available sections and
variables here <#Settings> See Syntax #settings.conf syntax (#settings.conf syntax) ###
settings.conf syntax
the syntax of the settings.conf (#Settings) is quite simple and similar to a "*.ini" file,
there are 4 different elements. 1. Sections 2. Settings 3. Values 4. Comments
A comment starts with a # and is ignored by Fenrir. # this is a comment To group settings
we have sections. A section can look like this: [Section] A setting looks like this:
settingName=Value
Example: sound (#sound) # Turn sound on or off: enabled=True # Select the driver used to
play sounds, choices are genericDriver and gstreamerDriver. # Sox is default.
driver=genericDriver
Settings
Sound
The sound is configured in section ''sound (#sound)''.
Turn sound on or off: enabled=True Values: on=''True'', off=''False''
Select the driver used to play sounds. The genericDriver using Sox is the default.
driver=genericDriver
Available Drivers:
• ''genericDriver'' using the generic driver, for Fenrir <1.5 just use ''generic''
• ''gstreamerDriver'' using the gstreamer, for Fenrir <1.5 just use ''gstreamer''
These are the pack of sounds used for sound icons. theme=default By default we ship two
sound packs. 1. ''default'' opus encoded, for newer Sox versions 2. ''default-wav'' wav
encoded, just for compatibility Sound packs are located at
/usr/share/sounds/fenrirscreenreader/
Sound volume controls how loud the sounds for your selected sound pack are. volume=1.0
Values: ''0.0'' is quietest, ''1.0'' is loudest.
Generic Driver
The generic sound driver uses shell commands for play sound and frequencies.
''genericPlayFileCommand'' defines the command that is used to play a sound file.
genericPlayFileCommand=<your command for playing a file> ''genericFrequencyCommand''
defines the command that is used playing frequencies.
genericFrequencyCommand=<your command for playing a frequence>
The following variables are substituted in ''genericPlayFileCommand'' and
''genericFrequencyCommand'':
• ''fenrirVolume'' = the current volume setting
• ''fenrirSoundFile'' = the sound file for an sound icon
• ''fenrirFrequence'' = the frequency to play
• ''fenrirDuration'' = the duration of the frequency
Example genericPlayFileCommand (default) genericPlayFileCommand=play -q -v fenrirVolume
fenrirSoundFile Example genericFrequencyCommand (default) genericFrequencyCommand=play -q
-v fenrirVolume -n -c1 synth fenrirDuration sine fenrirFrequence ### Speech
Speech is configured in section ''[speech]''. Turn speech on or off: enabled=True Values:
on=''True'', off=''False''
Select speech driver, options are speechdDriver (default),
genericDriver or espeakDriver:
driver=speechdDriver #driver=espeakDriver
driver=genericDriver
Select the driver used to generate speech output.
driver=speechdDriver
Available Drivers:
• ''genericDriver'' using the generic driver, for Fenrir <1.5 this is not available
• ''speechdDriver'' using speech-dispatcher, for Fenrir <1.5 just use ''speechd''
• ''espeakDriver'' using the espeak directly, for Fenrir <1.5 just use ''espeak''
The rate selects how fast Fenrir will speak. rate=0.65 Values: Range Minimum:''0.0'' is
slowest, Maximum:''1.0'' is fastest.
Pitch controls the pitch of the voice. pitch=0.5 Values: Range Minimum:''0.0'' is lowest,
Maximum:''1.0'' is highest.
A Pitch for capital letters can be set. capitalPitch=0.9 Values: Range Minimum:''0.0'' is
lowest, Maximum:''1.0'' is highest.
The Volume controls the loudness of the voice. volume=1.0 Values: Range Minimum:''0.0''
is quietest, Maximum:''1.0'' is loudest.
Some speech drivers like speechdDriver can support various modules. these can be set
here. module=espeak Values: Text, Consult speech-dispatcher's configuration to see what
modules are available.
Voice selects the varient you want to use, for example, f5 will use the female voice #5 in
Espeak, or if using the Espeak module in Speech-dispatcher. To find out which voices are
available, consult the documentation provided with your selected synthesizer. voice=
Values: Text, see your TTS synths documentation what is available.
Select the language you want Fenrir to use. language=english-us Values: Text, see your
TTS synths documentation what is available.
Read new text as it occurs autoReadIncoming=True Values: on=''True'', off=''False''
Generic Driver
The generic speech driver uses shell commands for speech synthisus.
''genericSpeechCommand'' defines the command that is executed for creating speech The
following variables are substituted in ''genericSpeechCommand'':
• ''FenrirText'' = is the text that should be spoken
• ''fenrirModule'' = may be the speech module like used in speech-dispatcher, not every
TTY needs this
• ''fenrirLanguage'' = the language to speak in
• ''fenrirVoice'' = is the current voice that should be used
• ''fenrirVolume'' = is replaced with the current volume
• ''fenrirPitch'' = is replaced with the current pitch
• ''fenrirRate'' = is replaced with the current speed (speech rate)
Example genericSpeechCommand (default): genericSpeechCommand=espeak -a fenrirVolume -s
fenrirRate -p fenrirPitch -v fenrirVoice "fenrirText"
These are the minimum and maximum values of the TTS system used in genericSpeechCommand.
They are needed to calculate the abstract range in volume, rate and pitch 0.0 - 1.0.
FenrirMinVolume=0
fenrirMaxVolume=200
fenrirMinPitch=0
fenrirMaxPitch=99
fenrirMinRate=80
fenrirMaxRate=450
The current volume, pitch and rate is calculated like this value = min +
[volume,pitch,rate] * (min - max ) ### Braille

Scripting
Scripts can be in any language, bash, python, sh or others. Place your scripts in the
directory /usr/share/fenrirscreenreader/scripts/ (the path is configurable in
settings.conf). The script key is the applications key. Usually this key can be found on
the keyboard located just left of the right most control key. When you name a script, the
key name appears in the script seperated by the sequence -. So, for example, if you have
a python weather script you want assigned to the script key plus the letter w you would
name the script /usr/share/fenrirscreenreader/scripts/weather__-__key_w.py Then, to access
the script, simply press the script key and the letter w. Scripts must be executable.
So, make sure to chmod 755 your script when you place it in the scripts directory. The
script gets some parameters from fenrir when it is executed. So that information is
available in your script then.
Parameterlist
Parameter Content
─────────────────────────────────────────────
$1 Username of the current logged
in user
Examples
Script that just speaks the current username when pressing ScriptKey + H.\ File:
''/usr/share/fenrirscreenreader/scripts/helloWorld__-__key_h.sh'': #!/bin/bash echo $1
Commands
You can place your own commands in "/usr/share/fenrirscreenreader/commands" (path is
configurable in settings.conf). Commands are python files with a special scheme. You can
assign them to a shortcut using the filename without an extension or place them in a hook
trigger like OnInput or OnScreenChange. For further information see developer guide.
Good Examples: "date.py"
(https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/date.py)
(announce the Date), "shut_up.py"
(https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/shut_up.py)
(interrupt output) the basic scheme for a command is as follows:
from core import debug
class command():
def __init__(self):
pass
def initialize(self, environment):
self.env = environment
def shutdown(self):
pass
def getDescription(self):
return _('No description found')
def run(self):
pass
def setCallback(self, callback):
pass
• Template lives here
(https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/command_template.py)
• The class needs to have the name "command".
• "initialize" is running once whilst loading the command.
• "shutdown" is running on unload like the command (quit fenrir)
• "getDescriptsion" just returns an string. That String is used in Tutorial Mode.
• "run" is executed when the command is invoked. (shortcut is pressed, or trigger isn't
running)
• setCAllback is currently not used. and has no functionality yet.
Troubleshooting
Fenrir does not start
1. Have you installed all the dependencies Support and Requirements (#Support and
Requirements)
2. Try using master, a lot of changes take place there to make Fenrir compatible with
more systems ## Fenrir does not utilize the shortcuts
3. Make sure you have python3-evdev installed
4. Use the latest Fenrir version
5. Make sure that Fenrir has permission to /dev/input/* and /dev/uinput (or run it as
root) ## No sound at all
6. Run the script to configure Pulseaudio once as root and once as your user. This will
setup Pulseaudio but require a restart of Pulseaudio. The script is located in
''tools/configure_pulse.sh''
7. Use ALSA
8. Configure Pulse system wide
(https///www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/)
(Not recommended)
9. Use gstreamerDriver: change ''settings.conf'' in the section ''sound'' the line
''driver=genericDriver'' to ''driver=gstreamerDriver''
10. Use wave sound-icons: change ''settings.conf'' in the section ''sound'' the line
''theme=default'' to ''theme=default-wav''
11. Use most current version of sox (http://sox.sourceforge.net/) with opus support
12. Try apulse (https///github.com/i-rinat/apulse) (not tested by myself but might work).
Please give me feedback if you try it out. ## You get sound-icons but no speech
13. If you are using speech-dispatcher run "spd-conf" once as user and as root.
14. You can test if speech-dispatcher works by invoking it as root\ ''sudo spd-say "hello
world"'' ## Bugreports and feature requests
Please report Bugs and feature requests to: https://github.com/chrys87/fenrir/issues
