Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This cheatsheet is written by @TSiege. You can check the original version of cheatsheet at link

This list is meant to be both quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

--server-connect

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:

Haxe FrontEnd

Reads haxelib-lock.json (if exists)

Reads <file> (if called with -lock-file <file>) which will partially override haxelib-lock.json

Takes arguments (hxml files or anything else)

Expand hxml files to their actual content
