"a, "o, and "u into their respective
Umlaute.Parser rules are defined via simple rule files. The rules for the above example would be defined in the following way - for both upper and lower case Umlaute:
Each line in a rule file declares a translation from an input sequence into an output sequence. In this example, the output sequences are single characters, which is the normal case, but sequences can be used here as well. Both sequences have to be separated by a single tabulator. No other white space characters are allowed. The sequences themselves may not contain tabulators."a "A Ä "o "O Ö "u "U Ü
To make your parsing rules available in Babbletower, save the rules in a file with the ending
.prs. Choose a short file name. The encoding of the file has to be in UTF8. Place the
file in the ime directory, located in Babbletower's directory. When
Babbletower starts up, it loads all .prs files contained in it and makes them
available in the drop down list of the input method chooser.
" is entered. It will stop highlighting the text
when a non-ambiguous or no translation for the input sequence is found, e.g. if the next entered letter
in our example is a, the parser would change the sequence "a into
ä, and remove the highlighting.
If there were another rule starting with the same sequence, e.g. "aa ää, the parser would
only change the entered "a, but not remove the highlighting. This is to show
that there is a further alternative in the rule set. If now a second a is entered, the text
will change from ä into ää, and the highlighting is removed. If the first
alternative is what you want, hit Enter.
To activate autocomplete for a set of rules, the first line in a rules file has to consist of the word
autocompelete. This mode is usually used with simple rules as in our example.
