| |
| Introduction |
| ------------ |
| |
| Liblouis is an open-source braille translator and back-translator. It |
| features support for computer, literary and math braille, supports |
| contracted and uncontracted translation for many, many languages[1]. |
| It plays an important role in an open source accessibility stack and |
| is used by screenreaders such as NVDA and Orca. A companion project |
| liblouisutdml/liblouisxml[2] deals with formatting of braille. |
| |
| Changes in this release |
| ----------------------- |
| |
| This release contains a tremendous amount of work many developers. |
| Many long standing bugs have been fixed. The tables can finally be in |
| UTF-8. A grand table cleanup removed duplication from the tables. |
| There are now two extensive test frameworks for table writers. A |
| number of new tables have been contributed on top of the usual |
| assortment of table improvements. Thanks to all of this liblouis has |
| already seen quite a bit of uptake in a number of places, notably the |
| new DAISY pipeline will ship with this release of liblouis. |
| |
| NOTE: If you have private tables you might want to migrate them to |
| utf-8. To do this just use iconv as follows: |
| |
| $ iconv -f latin-1 -t utf-8 <input >output |
| |
| New features |
| ~~~~~~~~~~~~~ |
| * New Braille tables |
| - Estonian grade 0, thanks to Jürgen Dengo. |
| - Portuguese 8 dot Computer braille, Thanks to Rui Fontes |
| * UTF-8 support in tables |
| Braille tables can now contain UTF-8 in the opcode arguments. |
| * Improvements to the python bindings |
| All constants defined in liblouis.h are now exposed in the bindings. |
| * Add a doctest infrastructure |
| These tests are based on the Python doctest framework and are only |
| run if there is a Python interpreter on the system |
| * Add a test harness |
| This test infrastructure allows the user to do table tests in a |
| simple and concise syntax. These tests are based on the Python |
| nose testing framework and are only run if either Python 2.x or |
| 3.x with the related nose python module is installed on the |
| system. See the documentation for more information. Thanks to |
| Mesar Hameed. |
| * Add a test harness generator |
| A harness generator that uses simple text files with a little |
| formatting to help to generate the json harness files. The purpose |
| of this tool is to make it much easier and faster to add checks |
| for a given table. You are expected to read the generated harness |
| file and make necessary changes, the tool only helps you to get |
| the tests into the harness format, not check their validity. |
| * Support for Python 3 in the Python bindings |
| The Python bindings now work for both Python 2 and Python 3. |
| Thanks to Michael Whapples. |
| |
| Improved C-based test framework |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| - Improved the test framework to be able to test translations |
| involving Unicode. |
| - Added numerous tests, e.g. for lowercase and Unicode, for the |
| input position, for repeated, etc. |
| |
| Improved the documentation |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| - Document the test harness (json format, fields, flags). |
| - Document the use of Valgrind to find memory leaks |
| - Improve the documentation on the display opcode |
| |
| Bug fixes |
| ~~~~~~~~~~ |
| - lou_allround and lou_translate now properly handle Unicode |
| characters |
| - Fix some issues reported by Valgrind |
| - Fix inputPos for situation where context and multipass opcodes |
| are involved |
| - Fixed a number of bugs with the letter, uppercase and lowercase |
| opcodes when dealing with Unicode |
| - Fixed a couple of bugs with hyphenation (documentation, Python |
| bindings and a number of buffer overruns in the C library). |
| Thanks Milan Zamazal <pdm@brailcom.org> for reporting this. |
| - Fix a bug in the $a. matcher in the multipass rules where only 32 |
| chars were matched. It now matches 0xffff chars. |
| - Fix a bug reported by James Teh related to pass1Only |
| |
| Braille Table Improvements |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| - all table files have consistent encoding, UTF-8. |
| - The grand table cleanup: Reorganize the tables to remove |
| duplication. Move common parts such as Latin letter, eight and |
| six dot digit definitions to separate files which are then |
| included. This should ease table maintenance. Thanks to Mesar Hameed. |
| - Fixes to de-de-comp8.ctb thanks to Aliminator83@gmail.com |
| - hu1.ctb renamed to hu-hu-g1.ctb |
| - hu.ctb renamed to hu-hu-comp8.ctb |
| - eo.ctb renamed to eo-g1.ctb |
| - Fixes to eo-g1.ctb thanks to Aaron Cannon <cannona@fireantproductions.com> |
| - hu-hu-g1.ctb: improvements and extensive test harness, with |
| working back-translation, Thanks to Hammer Attila |
| - Fixes to fr-bfu-comp6.utb and fr-bfu-comp8.utb thanks to Michel |
| Such <michel.such@free.fr> |
| - Fixes to no-no-g3.ctb thanks to Lars Bjørndal |
| <lars@lamasti.net> |
