unrelated to your question but this is no longer the recommended way
to use harf mode in latex. 

After some discussion the latex team decided to build lualatex next
year over luahbtex. For testing purpose lualatex-dev already now
uses luahbtex. harftex has been archived and its development has
stopped. The harfload code has been integrated into luaotfload.
Also fontspec has been updated and offers keys to activate harf
mode.

So your document should look like this:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{font}[Renderer=Harfbuzz] 
...

This requires a current luaotfload and you should use lualatex-dev
to compile it.

[NTG-context] Using ConTeXt with LuaTeX variants

2019-12-05 Thread Jairo A. del Rio 
Hi. How do I build the format? I try

context --make

ANd nothing special happens. How do I set up the new engine. Thank you in
advance.

What should I do? Thank you in advance


First of all you should rebuild the format with the new engine.

context --make

Then you will have to write backend code that exposes the mode=harf
to the ConTeXt font loader.
