Version 1.14 of package Multi-Mode has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Multi-Mode describes itself as: ================================ support for multiple major modes ================================ More at https://elpa.gnu.org/packages/multi-mode.html ## Summary: This is a framework for a sort of meta mode which provides support for multiple major modes in different regions (`chunks') of a buffer -- sort of. Actually, multiple indirect buffers are used, one per mode (apart from the base buffer, which has the default mode). A post-command hook selects the correct buffer for the mode around point. This is done on the basis of calling the elements of `multi-chunk-fns' and taking the value corresponding to a start position closest to point. ## Recent NEWS: [Not provided 🙁]
