The source is considered part of the ConTeXt distribution +and managed by the ConTeXt development team and the ConTeXt user group. That way we can guarantee +that the engine and this TeX macro package work together as expected. The idea is that users can +easily compile the source themselves and that way have a guaranteed long term (minimal) TeX based +installation. Because the management scripts are in Lua, only one binary is needed to serve the +ConTeXt distribution. + +In the source code we try to stay close to the ancestors, LuaTeX, pdfTeX, eTeX and TeX, but in the +meantime due to additions there is quite some diverge. There are new primitives and submechanisms, +there is more control over the inner workings, font handling is mostly delegated to Lua and there +is no built-in backend. The code base is all-inclusive and has no (nor will have) dependencies on +external libraries. + +Performance and memory consumption have been optimized and the additions (compared to LuaTeX) don't +have a negative impact. In spite of the extensions, we consider this a more lightweight version of +its ancestor and want to keep it that way. There are a few optional interfaces to the outside world +but ConTeXt will never depend on them for regular usage. + +Version numbering starts 2.00 so that there is no confusion with LuaTeX where the stable 1.00+ +version numbers now can bump with the yearly TeXlive updates. Backporting features to LuaTeX is yet +undecided (also because the codebase is now too different). The internal MetaPost library is an +enhanced version of the official one that ships with LuaTeX. Here we started with number 3.00 and +to what extend there will be backports to the 2.00+ library is yet unknown. We use Lua 5.4+ and try +to keep up to date with the latest greatest, also because the LuaMetaTeX-ConTeXt combination makes +for nice test enviroment. Starting with LuaMetaTeX version 2.10 the interfaces are considered +stable. Although we will fix bugs as fast as possible, we might end up with the same slow-paced +release cycle as traditional TeX. + +Bugs can be reported to the ConTeXt mailing lists (support or development) or the team members. Such +a report should come with a (MEW) ConTeXt .tex file that illustrates the issue. The code repository +is managed by the ConTeXt user group and its compile farm team (aka contextgarden built bot). + +All kind of aspects of the LuaMetaTeX engine, its development, experiment, ideas and implementation +have been (and are) reported in user group publications aas well as several documents in the ConTeXt +distribution. The mailing list archives and contextgarden wiki are also a source of information. + +Hans Hagen |
