Hi all

I have my dot files in orgmode format and have been using it for a year or
so with great success. today i noticed that code block (conf blocks) that i
used to tangle recursively have stopped working and i get this error

org-babel-execute-src-block: No org-babel-execute function for conf!


this is an example of how the code block looks


*** sxhkd
