yasr is a lightweight, portable screen reader. It works by opening a
shell in a pty and intercepting all user input/output, maintaining a
window of what should be on the screen by looking at the codes and text
sent to the screen. It only requires that the user be able to access
the text to speech (TTS) device.
yasr was originally designed in conjunction with a Speak-out TTS
device. Yasr also attempts to support DEC-Talk, DoubleTalk, Apollo,
and ViaVoice Outloud, but more work is needed to get these to work
fully. It may be able to work with Emacspeak servers, however.
Currently yasr has two sets of keymaps, one for
"review mode" (ie,
reviewing the screen) and
one for the standard mode. Keys defined for
the standard mode are checked irrespective of whether the user is in
review mode or standard mode, but the review mode keymap is checked
first in the former case.
- -C config_file
The configuration file that yasr should use.
Attempts to emulate bash's -c command. It runs /bin/sh, passing
it the arguments that were passed to yasr.
- -s synthesizer
The TTS synthesizer to use in conjunction with yasr.
See the [options] section of
the config file.
- -p synthesizer_port
The port that the TTS synthesizer is connected to.
See the Synopsis for examples.
yasr will also fork and exec a program to run, if it (and any optional
command line arguments it needs) are given as the last command line
