== Fenrir User Manual for Slint users
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.
=== Credit and intended audience
This document is just a customization for Slint of the genuine
https://github.com/chrys87/fenrir/blob/master/docu/user.txt[Fenrir User
Manual] motly written by Chrys, main developer of Fenrir.
It has been adapted to its intended audience: end users of Fenrir on
Slint where it is already installed, thus concentrates on its setting
and usage. You will find more information about its features,
installation and how customize and troubleshoot it and contribute to its
development on https://github.com/chrys87/fenrir[the Fenrir Git
repository].
=== Getting started with Fenrir
Fenrir is a screen reader, that reads aloud the text displayed on the
screen and allows to review it, like espeakup and speechd-up also
shipped in Slint. +
In Slint it is mostly used in console mode, and uses the synthesizers
and voices provided by Speech Dispatcher. +
Keyboard shortcuts are bound to commands to read the screen, review it
and perform other actions like modify the settings on the fly, switch
languages, copy and paste text, provide miscellaneous information. +
=== Configuration file === The permanent settings are recorded in the
configuration file /etc/fenrirscreenreader/settings.conf, that is
heavily commented. +
These settings are described in this user guide.
To start Fenrir once type as root:
....
service start fenrir
....
To enable auto start on system boot type as root:
....
speak-with fenrir
....
and confirm that you want to have it started at boot time.
If you are using Fenrir for the first time you may want to take a look
at these resources:
* link:#Keybindings[Keybindings]
* link:#Tutorial Mode[Tutorial Mode]
== Keybindings
Two series of key bindings are provided:
. the link:#Desktop layout[Desktop layout] uses a numeric keypad (here
abbreviated as keypad).
. the link:#Laptop layout[Laptop layout] for keyboards that do not have
a numeric keypad.
The layout is set in the configuration file in the section
link:#Keyboard[Keyboard].
=== 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:
. Insert
. KeyPad Insert
. Meta (Super, Windows)
=== Script Key
To invoke "Scripts" the Script Key is mandatory. The shortcut is encoded
in the filename of the script. See link:#Scripting[Scripting]
By default the Script Key is Compose (the key between AltGr and Ctrl at
the right of the space bar).
For instance, pressing Script Key + L switches between the languages
possibly listed in the configuration file. Feel free to write you own
scripts to expand Fenrir features and share them!

The settings proposed below can be implemented editing in the
link:#Configuration file[configuration file]
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 respected before 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 link:#Promote[Promote] in `+settings.conf+` for more
information.
=== 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 to be set in the link:#Configuration file[configuration file]
....
[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
The default punctuation settings are recorded in thd directory
/etc/fenrirscreenreader/punctuation/default.conf
===== 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):
. Commandline Parameters `+-o+` see link:#Set settings options[Set
settings options]
. /etc/fenrirscreenreader/settings/settings.conf see
link:#Settings[Settings]
. hard coded defaults
=== Commandline Arguments
==== Set settings options
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 link:#settings.conf syntax[#settings.conf syntax]
==== settings.conf syntax
the syntax of the link:#Settings[settings.conf] is quite simple and
similar to a "*.ini" file, there are 4 different elements.
. Sections
. Settings
. Values
. 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]
# 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]+`.
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.
. `+default+` opus encoded, for newer Sox versions
. `+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
This Selects the driver used to generate speech output.
We recommend top keep the default in Slint to benefit of all available
synthesizers and associated voices
The rate selects how fast Fenrir will speak.
....
rate=0.5
....
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.
The Module sets here selects the synthesizer to use by
speech-dispatcher. If not set, the one set in
/etc/speech-dispatcher/speechd.conf will be used. +
TO list the available modules, type:
....
spd-list -s
....
To be able to switch languages on the fly, set below a module that
supports all languages between which you want to be able to switch. +
To make this choice type:
....
spd-list
....
Example of module setting:
....
module=espeak-ng
....
Voice selects the voice you want to use. This setting won't hold if you
switch languages on the fly (see below) or also set the language. +
To find out which voices are available, for a given module, type:
....
spd-say -o <module> -L
....
For instance:
....
spd-say -o rhvoice -L
....
If you use the module espeak-ng or espak-ng-mbrola-generic , you can
also run:
....
espeak-ng-list-voices
....
Example using the pico module:
....
voice=virginie
....
Languages lists the languages among which to switch pressing:
....
Compose+l
....
The Compose key is the one between AltrGr and Ctrl on the right of the
space bar. +
For the module in use, the languages available can be listed with
typing:
....
spd-list -ls <module>
....
For instance:
....
spd-list -ls espeak-ng-mbrola-generic
....
Be careful: all languages listed below should be provided by the module
in use, else switching languages on the fly won't be possible. Example
using the pico module:
....
languages=en-GB fr-FR es-ES it-IT
....
You can also set the language to use by default, which doesn't need to
be listed among the ones you might want to switch (but then you will
need to restart fenrir to get it back). +
It will supersede the voice that you might have also set. Example using
the pico module:
....
language=de-DE
....
Read new text as it occurs autoReadIncoming=True Values: on=`+True+`,
off=`+False+`
==== Screen
The settings for screens, (TTY, PTY) are configured in the `+[screen]+`
section.
The driver to get the information from the screen:
....
driver=vcsaDriver
....
Available Drivers:
* `+vcsaDriver+` using the VCSA driver (for TTYs), for Fenrir <1.5 just
use `+vcsa+`
The encoding of the screen
....
encoding=cp850
....
Values:`+cp850+` is used for Western languages like USA or Europe.
The driver updates Fenrir with changes on the screen.
....
screenUpdateDelay=0.05
....
Values: in Seconds
If you want Fenrir to not be active on any screen for various reasons.
Maybe an X server or Wayland is running on that screen. You can make
Fenrir ignore it or multiple screens seperated by `+,+` with:
....
suspendingScreen=
....
Values: Depends on driver:
* VCSA: the number of the TTY. TTY6 is `+6+`.
Example ignore TTY1 and TTY2:
....
suspendingScreen=1,2
....
There is also the ability to let Fenrir auto detect screens that are
running an X server. So Screens running an GUI can be ignored.
....
autodetectSuspendingScreen=True
....
Values: on=`+True+`, off=`+False+`
==== Keyboard
The settings for keyboard and input related configuration is located in
the section `+[keyboard]+` of the `+settings.conf+` file.
Select the driver used for grabbing keybord input and for recieving
shortcuts.
....
driver=evdevDriver
....
Values: Text, available Driver Available Drivers:
* `+evdevDriver+` uses the evdev input system of linux, for Fenrir <1.5
just use `+evdev+`
You can let Fenrir know about what input devices are to be used.
....
device=ALL
....
Values:
* `+ALL+` use all devices with key capabilities.
* `+NOMICE+` Exclude mices from handling.
* `+<Device Name>+` just use the device with the given name.
Gives Fenrir exclusive access to the keyboard and lets it control
keystrokes. This is needed to intercept Fenrir related shortcuts.
....
grabDevices=True
....
Values: on=`+True+`, off=`+False+`
The following makes sense if you are using a second screenreader and
want to have some hooked events. Fenrir ignores all shortcuts then.
....
ignoreShortcuts=False
....
Values: on=`+True+`, off=`+False+`
The current keyboard layout used for shortcuts.

== Customization
=== 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 [.underline]#-#.
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[.underline]##-##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
[cols=",",options="header",]
|===
|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:
https://github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/date.py["date.py"]
(announce the Date),
https://github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/shut_up.py["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
....
* https://github.com/chrys87/fenrir/blob/master/src/fenrir/commands/command_template.py[Template
lives here]
* 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
Below are fenric instructions that do not all apply to Slint.
Slint users may request help on the Slint mailing list.
=== Fenrir does not start
. Have you installed all the dependencies
link:#Support and Requirements[Support and Requirements]
. Try using master, a lot of changes take place there to make Fenrir
compatible with more systems
=== Fenrir does not utilize the shortcuts
. Make sure you have python3-evdev installed
. Use the latest Fenrir version
. Make sure that Fenrir has permission to /dev/input/* and /dev/uinput
(or run it as root)
=== No sound at all
. 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+`
. Use ALSA
. https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/[Configure
Pulse system wide] (Not recommended)
. Use gstreamerDriver: change `+settings.conf+` in the section `+sound+`
the line `+driver=genericDriver+` to `+driver=gstreamerDriver+`
. Use wave sound-icons: change `+settings.conf+` in the section
`+sound+` the line `+theme=default+` to `+theme=default-wav+`
. Use most current version of http://sox.sourceforge.net/[sox] with opus
support
. Try https://github.com/i-rinat/apulse[apulse] (not tested by myself
but might work). Please give me feedback if you try it out.
=== You get sound-icons but no speech
. If you are using speech-dispatcher run "spd-conf" once as user and as
root.
. 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
