| liblouis 3.35.0 has been released |
| |
| The liblouis developer team is proud to announce the liblouis release |
| 3.35.0. The release is available for download at: |
| |
| https://github.com/liblouis/liblouis/releases |
| |
| 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, Orca and JAWS. A companion project |
| liblouisutdml [2]_ deals with formatting of braille. |
| |
| Noteworthy changes in this release |
| ================================== |
| |
| This release brings quite a few technical improvements. We've enhanced |
| support for memory management in the API, added support for math |
| characters in ``match`` rules, expanded the Python bindings to include |
| metadata API support, and made it possible to set the log level via the |
| ``LOUIS_LOGLEVEL`` environment variable. |
| |
| There are also substantial updates to various language tables, including |
| improvements to Portuguese 8-dot braille, Hebrew back-translation, |
| Norwegian 8-dot support, UEB forward translation, and Hungarian braille. |
| We've added support for Rokuten Kanji (Japanese Kanji Braille). Russian, |
| Ukrainian, and Belarusian literary braille tables have received updates |
| to their space handling rules, and the Danish tables have seen fixes |
| related to typos and hyphenation. |
| |
| I'd like to thank everybody for helping to bring liblouis forward. |
| |
| For a detailed list of all the changes refer to the list of closed |
| issues [3]_. |
| |
| New features |
| ------------ |
| |
| - ``match`` rules now also support testing for math characters. Thanks |
| to James Bowden for the idea and Bert Frees for the implementation. |
| - Add Support for "Rokuten Kanji", the other Japanese system for Kanji |
| Braille. |
| - The API now contains functions to free memory that was returned by |
| API calls. See the documentation for details. Thanks to Leonard de |
| Ruijter. |
| - The Python bindings now support most of the metadata API, thanks to |
| Leonard de Ruijter. |
| |
| Bug fixes |
| --------- |
| |
| - ``ucBrl`` in the mode parameter now correctly works also for |
| back-translation. Thanks to Bert Frees. |
| - Fix a segfault when a StringBuffer is used before it is initialized. |
| Thanks to Anthony Tibbs. |
| - Fix a bug in the handling of ``nocont`` in conjunction with |
| ``seqdelimiter``. Thanks to Bert Frees. |
| |
| Braille table improvements |
| -------------------------- |
| |
| - Improvements to the Portuguese 8-dot Braille table: Correct angle |
| quotation mark characters used in Portugal, add missing symbols, such |
| as Greek alphabet and double quotation mark characters used in |
| Brazil. Also added symbols that aren't defined in the Portuguese |
| standard but are commonly found in texts and web pages, such as |
| bullet points, some common mathematical symbols, etc. Thanks to Tiago |
| M. Casal. |
| - Fix the back-translation of the Greek Sigma and other small |
| improvements to the Hebrew table. Thanks to Leonard de Ruijter. |
| - Improvements to Norwegian 8dot thanks to Lars Bjørndal. |
| |
| - Add more characters and math symbols. |
| - Fix a back-translation problem when two dot 6 are followed by a |
| word. |
| - Fix a problem where the letter "i" is followed by number. |
| |
| - Improvements to UEB forward translation, in particular fixes for |
| rarer words and some proper names. Thanks to James Bowden. |
| - Hungarian improvements thanks to Attila Hammer. |
| - Fix typos and hyphenations in the Danish tables thanks to Bue |
| Vester-Andersen. |
| - Improvements to the back translation for the Russian literary Braille |
| table: Now, if a space is intentionally input after a comma or |
| semicolon, a double space will not occur. If no space was input, a |
| space will still be automatically added, as before. This change also |
| applies to Ukrainian and Belarusian literary Braille tables. Thanks |
| to Andrey Yakuboy. |
| |
| Other changes |
| ------------- |
| |
| - Hans Anton Ålien proof read the documentation and fixed quite a few |
| typos. |

| ``LOUIS_LOGLEVEL`` environment variable. |
