lou_translate - Man Page

A Braille translator for large scale testing of liblouis Braille translation tables


lou_translate [Options] TABLE


Translate whatever is on standard input and print it on standard output. It is intended for large-scale testing of the accuracy of braille translation and back-translation.

TABLE is either

- a query


- a file list



-h,  --help

display this help and exit

-v,  --version

display version information and exit

-f,  --forward

forward translation using the given table

-b,  --backward

backward translation using the given table If neither -f nor -b are specified forward translation is assumed


lou_translate language:en grade:2 region:en-US < input.txt

Do a forward translation of English text to grade 2 contracted braille according to the U.S. braille standard.

lou_translate --forward en-us-g2.ctb < input.txt

Do a forward translation with table en-us-g2.ctb.

lou_translate unicode.dis,en-us-g2.ctb < input.txt

If you require a specific braille encoding use a display table. Here we do a forward translation with table en-us-g2.ctb and a display table for Unicode braille. The resulting braille is encoded as Unicode dot patterns. When you specify a table query, the braille encoding is always Unicode dot patterns.

echo ",! qk br{n fox" | lou_translate --backward en-us-g2.ctb

Do a backward translation with table en-us-g2.ctb.
