go get lonnie.io/e8vm/...

Project goal: a self-contained simulated computer system, including:

• arch8: A simulated dead simple instruction set that is barely enough for writing an OS (done).
• asm8: An assembler for arch8 (done). Try it live!
• g8: A programming language that looks like Go but actually works like C (working on it).
• os8: A dead simple operating system that is written in g8 (not started).
• Since arch8 is dead simple, it can be easily ported to Javascript so that everything can run (slowly) in a browser.
• For self hosting, I could either rewrite everything in g8, or port golang to os8. Not sure which one is more practical.

Note: I paused the development because I started working at Google, and Google has some policies for hobby projects. I promise I will finish this when the time comes. If you would like to contribute, please contact me via email for copyright/license related details.

I hope the project can be readable like a novel. This is how I plan to achieve it:

• Use a simple language. Written in golang.
• Write in small files. Each file has no more than 300 lines, and each line contains no more than 80 chars.
• Keep no circular dependency. With no circular dependency among files, the project can be plotted as a DAG.

The DAG visualization gives the project an auto-generated "Table of Contents", where a reader can read the entire project from left to right in the graph. While the code might be still hard to read, I hope that now a reader can provide detailed feedback without the need to dive super deep first. For example, to read and provide feedback to the left-most block in a package, you now do not need to understand the details of any other blocks in the package, because the left-most block depends on nothing.

Try read the code here.

If you are just interested with the public interface, but does not care about the internal implementation, GoWalker can provide the docs: here.

To use the makefile, you also need to install some tools:

go get lonnie.io/e8tools/...
go get github.com/golang/lint/golint
go get github.com/jstemmer/gotags
