| liblouis 3.11.0 has been released | |
| The liblouis developer team is proud to announce the liblouis release | |
| 3.11.0. 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 | |
| ================================== | |
| A tremendous amount of work by Dave Mielke and Bert Frees has gone into | |
| this release. They have improved liblouis for use on note taker devices, | |
| for backwards translation and a number of languages. Many other | |
| contributors (listed below) have also helped in fixing bugs and | |
| improving braille tables, such as Dutch, Mongolian, Polish, Ancient | |
| Greek, Danish, Irish, Chinese, and American Braille Computer Code. | |
| For a detailed list of all the changes refer to the list of closed | |
| issues [3]_. | |
| New features | |
| ------------ | |
| - Enable ``always`` rules with a single character and a single braille | |
| cell for back-translation. Thanks to Bue Vester-Andersen. | |
| - Implement ``noUndefined`` mode for forward translation, thanks to | |
| Dave Mielke. | |
| - Use fallback braille representations (NABCC) for rendering undefined | |
| characters in hexadecimal notation, thanks to Dave Mielke. | |
| - Always render undefined characters, also ASCII characters, in | |
| hexadecimal notation. | |
| - Add a new metadata field ``index-name`` for selecting a table from a | |
| list fast and efficiently. It has the most important information | |
| first and no redundant information. It should look nice when sorted. | |
| This in contrast to the existing ``display-name`` field which is for | |
| describing a table accurately and should sound good. Thanks to Dave | |
| Mielke and Bert Frees. | |
| Bug fixes | |
| --------- | |
| - Don't let a caps passage end on a word with no letters. Thanks to | |
| Bert Frees. | |
| - Handle word resets in the last word of an caps or emphasis passage if | |
| the end indicator was placed before the word. Thanks to Bert Frees. | |
| - Never convert to lowercase if ``capsletter`` is not defined. Thanks | |
| to Bert Frees. | |
| - Fix position mapping for back-translation when ``noUndefined`` mode | |
| is active. Thanks to Dave Mielke. | |
| - Fix bug where a translation would hang on words that match both a | |
| ``nocont`` and a ``repeated`` rule. Thanks to Dave Mielke. | |
| - Fix bug where the effect of ``capsnocont`` would leak to the next | |
| word if that word starts with a capital. Thanks to Bue | |
| Vester-Andersen. | |
| Braille table improvements | |
| -------------------------- | |
| - Fix an issue with ordinal numbers inside caps passages in Dutch | |
| braille. Thanks to Bert Frees. | |
| - Improved back-translation for Mongolian thanks to Angaragerdene. | |
| - Fixes to Polish grade 1 and Polish computer braille thanks to Łukasz | |
| Golonka. | |
| - Improvements to Ancient Greek braille, which has been renamed | |
| "Greek international braille". A version with composed | |
| accents is made available as a .uti table. Thanks to Dave Mielke and | |
| Μαρια Γεωργακαράκου (Maria Georgakarakou). | |
| - Various improvements to modern Greek thanks to Dave Mielke. | |
| - Improvements and fixes to Spanish contracted braille. Details in | |
| #741. Thanks to Juan Pablo Bello. | |
| - Improvements and fixes to the Danish tables. Thanks to Bue | |
| Vester-Andersen. | |
| - Add a display table to match Word CX which is used in Norway and | |
| Sweden, and maybe also in other countries thanks to Lars Bjørndal. | |
| - Fix handling of colon within number in Dutch braille, thanks to Jake | |
| Kyle. | |
| - Fix translation of bullet and dot operators in Dutch braille, thanks | |
| to Paul Rambags | |
| - Added North American Braille Computer Code table (``en-nabcc.utb``) | |
| which is the counterpart of the ``text_nabcc.dis`` display table. | |
| Thanks to Dave Mielke. | |
| - Add support for the International Phonetic Alphabet (IPA) to the | |
| Chinese bopomofo braille table, thanks to Hurt Huang and Sponge Jhan. | |
| Various improvements, including dot patterns and test cases, to the | |
| Chinese bopomofo braille table, thanks to Sponge Jhan. | |
| - Unified English Braille no longer displays a single underscore when | |
| multiple underscores are in the text, thanks to André-Abush Clause. | |
| - Update to Afrikaans uncontracted braille and new table for contracted | |
| braille. Thanks to Christo de Klerk and Greg Kearney. | |
| - Update Irish braille (contracted and uncontracted) to the May 2019 | |
| version of the specification, thanks to Ronan McGuirk | |
| Other changes | |
| ------------- | |
| - The python wrapper now encodes and decodes strings to/from UTF-16 and | |
| UTF-32 using the surrogatepass error handler. This ensures that | |
| single UTF-16 surrogate characters are processed correctly by the | |
| wrapper and don't raise an encoding/decoding error. Thanks to Leonard | |
| de Ruijter. | |
| - Metadata keys and values are now case insensitive, thanks to Dave | |
| Mielke. | |
| - Remove ``unicodedefs.cti``. It was obsolete and never meant to be | |
| included by any tables. Instead use the online references as | |
| mentioned in the documentation now. See also #696. | |
| - ``lou_checkyaml`` test reporting has been improved, thanks to Bert | |
| Frees. For example it now has a ``--verbose`` option so that printing | |
| of expected failures can be enabled. | |
| - Hyphenation tables have been removed from tables except those needed | |
| for ``nocross`` rules, thanks to Bert Frees. | |
| The idea is that the caller (for example ``odt2braille`` or | |
| ``liblouisutdml``) should be able to decide for themselves which | |
| hyphenation table to use. The case in which a table contains nocross | |
| rules is an exception. In this case the hyphenation patterns are a | |
| real part of the table. Because it is not recommended to append an | |
| own hyphenation table in this case, a ``#-has-nocross`` metadata | |
| field was added to indicate that a table contains nocross rules. | |
| - ``lou_hyphenate`` can now handle more than just words (sequences of | |
| letters), e.g compound words, thanks to Bert Frees. | |
| Deprecation notice | |
| ------------------ | |
| - The ``noUndefinedDots`` mode has been renamed to ``noUndefined``. For | |
| backwards compatibility ``noUndefinedDots`` is still available in the | |
| header file and in the Python bindings, as an alias for | |
| ``noUndefined``. | |
| Backwards incompatible changes | |
| ------------------------------ | |
| None | |
| Invisible changes | |
| ----------------- | |
| - Internally separate more clearly the display and translation phases. | |
| New, renamed or removed tables | |
