How can I RPC from an external application into Emacs then have a function in Emacs handle the RPC?
For example, I would like to make a D3.js webpage with a dependency graph of a codebase, view and navigate the graph in Google Chrome, and clicking a node should tell Emacs to display a buffer of the given source file.
Minimal amount of code written would be nice, and preferably native Emacs functionality, unless 3rd party package is the only way.
