Rewrite rule examples contains (mostly) Estonian rewrite rule tables (documented in English). A rewrite rule table contains the following tab-separated columns:

  • Comment. Free-form comment
  • Locale. Regular expression to match the locale of the utterance (e.g. "et")
  • Service. Regular expression to match the recognizer service class name
  • App. Regular expression to match the app package name
  • Utterance. Regular expression to match (parts of) the utterance
  • Replacement. String that replaces the matched parts of the utterance
  • Command. Command to be called if the expression fully matches the utterance
  • Arg1. First argument of the command
  • Arg2. Second argument of the command

The first line of the table is a header that names the columns. The header is optional if the table contains a single column (interpreted as Utterance) or 2 columns (interpreted as Utterance and Replacement). Non-header lines can be commented out using an initial '#'.

Rewriting is done by:

utt = java.util.regex.Pattern.compile( Utterance ).matcher(utt).replaceAll( Replacement )

The pre-defined commands cover cursor movement within the text and between fields, selection, replacement, copy/paste/cut, and the editor actions search, send, go, and done. Most of the commands can be repeated or undone multiple times. The arguments can reference expression groups by $1, $2, ... and the current selection by @sel().

Changing preferences

In order to change multiple preferences automatically, you can use the adb-pref.py script which reads the set of preferences' key-value pairs from a set of YAML-files, and sends commands to Kõnele to change the respective preferences.

./adb-pref.py --disable-confirmation | sh
read
./adb-pref.py prefs_{developer,user_guide_rewrites,private}.yml | sh

Note that every preference has a type (Boolean, String, ...). If the type of a preference listed in the YAML-file does not match with the one expected by Kõnele, a crash can occur (ClassCastException), and part of Kõnele might become unusable (e.g. the Settings-activity does not open). In this case clear all Kõnele data via Android's system settings (app-specific Clear storage or Clear data, depending on your Android version), and fix the type in your YAML file.
