I've attached five small files to this message which illustrate a back
translation example that doesn't work but, according to my current
understanding as well as a bit of code inspection, should work. I'll also
explain these files.
tst-run: A script that runs the command:
lou_translate -b tst-ctb <tst-in >tst-out
tst-in: This is the input which is to be back translated. It contains two lines
that both say (without the quotes) ";abc". The first line is in characters
(semicolon, a, b, c), and the second is in Unicode braille patterns.
tst-out: The output, i.e. the actual back translation. Both lines are still
";abc". Both are in characters (semicolon, a, b, c).
This isn't what's supposed to happen. The rules in the table (see below) should
translate both lines to "xyz;". There are three rules:
;a -> x;
;b -> y;
;c -> z;
Each of these rules starts with _ so it should see the ; from the previous rule
application. Here's the atual table, followed by the trace. As you'll see, the
";a" isn't even processed as a pair.
letter a 1
letter b 12
letter c 14
letter x 1346
letter y 13456
letter z 1356
