Haxe 4.0 introduces a new way of communicating IDE and the compiler.

Here's what an IDE needs to do:

  • start a TCP server on some port (can pass 0 to bind to any available one)
  • start haxe --server-connect <port> where <port> is replaced with the port number the started TCP server was bound to.
  • haxe will connect to that server and await requests, ensure that happens
  • send messages of the following structure:

  • Uninstall OCaml, MinGW, Cygwin
  • Remove leftover environment vars, cleanup PATH
