| 3.20.0. 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 is a major release. Not only in terms of table additions and |
| updates but also in the way the tables are written. Bert has replaced |
| the ``uplow`` opcode with a more generalized ``base`` opcode. This |
| clears up the path for a more generalized handling of emphasis and |
| uppercase characters. In the course of this simplification some bugs |
| with computer braille were discovered and fixed. |
| |
| On the Braille tables side there is a brand new table for braille kanji |
| and there are major updates to the Polish, Chinese, Russian literary and |
| the UEB tables. |
| |
| 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 |
| ------------ |
| |
| - There is an experimental new feature that allows a table writer to |
| write table macros. This feature is disabled by default. Macros are a |
| helpful tool for refactoring, however as it stands the feature is not |
| mature and might disappear in future releases. |
| - Add a new opcode ``base`` that associates a character with another |
| already defined character. Think of it as a generalized form of |
| ``uplow``. A typical use of this opcode is for defining a pair of |
| letters, a lowercase and the corresponding uppercase. |
| |
| Bug fixes |
| --------- |
| |
| - Fix a problem with the dot 7 capitalization indicator in computer |
| braille thanks to Bert Frees. |
| |
| Braille table improvements |
| -------------------------- |
| |
| - New table for Kantenji (or "braille kanji", a Japanese |
| braille system) thanks to Kensaku Y. |
| - Improvements to Polish literary braille table thanks to Łukasz |
| Golonka. |
| |
| - use correct representation of indexes for squared, cubed etc. |
| - use correct representation for fractions |
| - change symbol used for underscore from dots 46 to 6 |
| - add U+2212 minus symbol (also to computer braille table) |
| |
| - Updates to the Chinese braille table (``zh-tw.ctb``) thanks to |
| Bo-Cheng Jhan. |
| |
| - Complete translation of CJK Radicals Supplement |
| - Change the default braille pattern of '蛤' to ⠗⠜⠂ |
| - Correct the default braille pattern of many Chinese characters |
| - Add various Chinese phrases involving exceptions of braille |
| patterns |
| - Add a math symbol '◊' (⠫⠓) |
| |
| - Improvements to the Russian literary (uncontracted and contracted) |
| braille thanks to Andrey Yakuboy. |
| |
| - If the dot sign ('.') is after digits at the beginning of a |
| string, the braille dot 6 isn't inserted between the last digit |
| and the dot. This is necessary for items' numbers of numbered |
| lists. |
| - Back translation for French letters has been disabled because of |
| conflicts with punctuations. |
| - Back translation for Latin (mostly English and German) letters has |
| been improved. |
| - The definition of the 7/8 fraction (U+215E) has been fixed. |
| - Placement of spaces around math symbols has been improved |
| according to the Russian braille rules. |
| - The apostrophe sign ("'") and the right tick sign |
| (u+2019) are displayed correctly if they're in the end of a word |
| (English, for example). |
| - New contractions have been added and minor bugs have been fixed in |
| the Russian contracted braille table. |
| |
| - New display table (``ru-brf.dis``) has been added. It adds support of |
| Braille ASCII for Russian and other Cyrillic tables. Thanks to Andrey |
| Yakuboy. |
| - Improvements to UEB thanks to James Bowden. |
| |
| - Fixed placement of numeric indicator in letters dot numbers. |
| - Added more mathematical symbols. |
| - Added the four new allowed shortform extension words. |
