Reaching the Unix Philosophy's Logical Conclusion with WebAssembly

Hey there! This is the example code I wrote for my talk at GopherCon EU. This consists of a few folders with code:

• cmd: Executable commands for the demo.
• cmd/aiyou: The WebAssembly runner. It connects to cmd/yuechu and exposes network connections as a filesystem. It is intended to run wasip1/echoclient.wasm.
• cmd/yuechu: The echo server that takes lines of inputs from network connections and feeds them to WebAssembly modules then sends the output back to the client. It runs wasip1/promptreply.wasm and wasip1/xesitemd.wasm.
• wasip1: A folder full of small demo programs. Each is built with makefile commands.
• wasip1/echoclient.wasm: A small Rust program that tries to connect to the echo server, prompts for a line of input, prints what it got back, and then exits.
• wasip1/promptreply.wasm: A small Rust program that reads input from standard in and then writes it to standard out.
• wasip1/xesitemd.wasm: My blog's markdown to HTML parser. It reads xesite-flavored markdown over standard input and returns HTML over standard output.

In order to build and run the code in this folder, you must be using Nix and be inside a nix develop shell. You can build most files in wasip1 by using make such as like this:

make echoreply.wasm promptreply.wasm
