Highlighting embedded code snippets in vim

Question

I often edit markdown files with in-line code examples. these all start with the line “~~~ {.cpp}” (for C++). Is there an easy way to highlight everything between the line “~~~ {.cpp}” and the line “~~~” with C++ syntax hightlighting?

(Or even better, make it use “x highlighting” after “~~~ {.x}”.)

Answer 1

Add the following to your syntax file for that file type, or just to your .vimrc

syn region myComment start="~~~" end="~~~" contained
hi def link myComment          Comment

This will tell vim to highlight those regions as comments.

Answer 2

This works for me. Maybe it is a starting point for further digging...
