Support

The LuaTeX project is focussed on the engine and not on its application. This means that support by the team is limited to the core functionality. We publish on a regular basis in the journals of local user groups and attend user group conferences where we present progress. So, it makes sense to join a (local) user group!

Specific support is provided via mailing lists. There are two lists that relate directly to LuaTeX:

a list for developers (hosted by the NTG)
a list for users (hosted by TUG)

The developers list deals with generic features of LuaTeX, bugs, compilation on specific platforms and integration in distributions. The user list is more focused on generic applications and usage. For support related to macro packages there are other platforms.

Portions of the right to left typesetting originate in Omega and its relative Aleph. Both these projects are no longer active. Basically only the directional support is kept and that is covered in manuals and example core by users.

Please don't use these list for discussions related to macro packages that use LuaTeX. These may use LuaTeX in different ways and you can best consult their respective places of support.

There is a LuaTeX Wiki for general issues. The wiki is independent and not maintained by the team.

If you are a ConTeXt user, you can best use one of the following lists:

a list for developers (hosted by the NTG)
a list for users (hosted by the NTG)

ConTeXt users can also find information about using Lua inside ConTeXt on the ConTeXt garden. The garden also has the latest binaries that we consider stable enough for production.

If you are a LaTeX user you can consult lists of your local user group (or the pdfTeX user list which is rather focused on LaTeX.) When you encounter problems with code that originates in ConTeXt, provide minimal examples and post them on one of the ConTeXt related lists.

ConTeXt comes in three flavours:

MkII: this version is meant for pdfTeX and XeTeX and its development is frozen per 2008 (of course bugs will be fixed.
MkIV: this version uses LuaTeX and we use it for (stress) testing and exploring new features. Per 2011 the code base is completely independent of MkII code.
MkXL: this version (aka LMTX) is used for the LuaMetaTeX follow up on the now frozen LuaTeX project.

Although the LuaTeX project is closely related to ConTeXt, we don't put specific functionality in there. LuaTeX is a generic engine with no hard coded solutions. If you have problems with MkIV which might use experimental features, please report them to the ConTeXt mailing lists and don't polute the LuaTeX mailing list with them.

The team members work LuaTeX in the spare time but are always willing to provide support on commercial basis. Of course we keep this independent of the ongoing development of a stable engine. In the spirit of TeX, there is are no secret and private versions of LuaTeX, we have just one community version.
