软件包摘要
Open-source braille translator and back-translator
历史
项目历史与用法
Liblouis is an open source braille translator and back-translator named for Louis Braille. It provides a C library, translation tables for many languages and braille codes, and command-line tools for checking, debugging, and testing braille translation tables.
项目历史
The Liblouis README says the project began in 2002 through ViewPlus, which wanted high-quality braille support as an open source effort and supported John Boyer with a monthly stipend so he could work with sighted assistants. The project was based on translation routines from the BRLTTY Linux screen reader but grew beyond those routines into a standalone shared library and Windows DLL.
Liblouis supports computer and literary braille, contracted and uncontracted translation, hyphenation, math braille, and a rule- or dictionary-based table system. Its manual is aimed both at people writing translation tables and programmers embedding the library.
采用历史
The README documents use in the NVDA and Orca open source screen readers and in commercial assistive technology from ViewPlus. Software Freedom Conservancy's March 17, 2025 announcement described liblouis as embedded in assistive technologies including screen readers, braille displays, Android devices, and iPhone devices.
A May 6, 2014 maintainership-succession announcement says John Boyer and ViewPlus initiated the Liblouis project twelve years earlier, and that Boyer built a community around it before passing maintainership to younger volunteers.
使用方式
Users commonly interact with Liblouis through programs such as lou_checktable, lou_debug, lou_translate, lou_trace, and lou_allround, or by linking the library from screen readers, embossing software, document converters, and mobile accessibility stacks. Table authors write text files with opcodes, includes, display rules, hyphenation support, and metadata.
为什么软件包爱好者会关心
Liblouis is significant because it turns braille translation into portable, inspectable data files plus a C ABI. For packagers, the table data, CLI validation tools, and library are inseparable: shipping the package means shipping both accessibility infrastructure and the tools to keep language-specific braille rules correct.
