[sharing] genexpr mode for emacs

Yes, if you are both an emacs user and a genexpr coder, then you may find my new project at https://github.com/larme/genexpr-mode interesting.

I'm the maintainer of genexpr mode for VSCode but as I write more and more genexpr, I found that mine only usage of VSCode is to write genexpr codes. Sometime I just want to write genexpr in terminal with my favorite editor emacs. That's why I made this emacs mode.

Currently it only support syntax highlighting and auto indenting. That's enough for me. But I will keep maintaining this mode and may add more features. You can install this mode manually or via package manager from MELPA. Please refer to the readme for more info.
