Eli, I’m finding c-ts-mode to get uglier and heavier in an unfortunate rate. Of course, I’m basically the defector maintainer now and the main person to blame for much of the complexity. We needed to add a lot of code and even hacks to make c-ts-mode work for complex C code.

A complicated and sometimes hacky c-ts-mode.el is bad for maintainability, and sometimes make c-ts-mode slow and unpleasant to use. More over, I feel that some people will look at c-ts-mode when looking for an example for writing a tree-sitter major mode. And c-ts-mode in its current state is not very suitable as an example.

Since a lot of the complexity are only needed by complex C code. I wonder if we can separate c-ts-mode.el into a simpler version that works for “modern” C and C++, plus an extra file that contains the additional things that makes it work for complex C code?

Yuan
