Hello,
In order to use another editor than Emacs and after testing Scite, I installed Textadept and modified the init.lua file as follows :

textadept.run.compile_commands.tex = 'mtxrun --autogenerate --script context --autopdf --purge --synctex = -1 "% f"'

The compilation works but no automatic output in pdf at the end of the process (as with Scite !)

What to do with files in /home /aragorn/context/tex /texmf-context/context/data /textadept/ context/ ?

Thank you.
Fabrice
