A book written in code that shows how computer works.

E8VM

Goal: A book written in working code and markdown document that describes how computer system works, including architecture, assemblers, compilers, and operating systems.

Read it here.

Planned Features:

• Modularized. File based modules. No circular dependency (not only on packages, but also on files). A reader can always read the project a file by a file, either from bottom to top, or from top to bottom.
• Small files. Each file is shorter than 300 lines of code.
• Tested and Documented. Each file (will) come with test cases, examples, and markdown description.
• Real. The simulation (will) work like a real computer.

TODOs

• Global VarDecl
• Type conversion
• Basic built-in panic
• Pointer
• Array and slice
• String
• Struct
• Fields and methods
• Interface
• Big number constants
• Unused variable check
• Unreachable code check
• Missing return check
• Break, continue with labels

Small things:

• VarDecl ast printing

And more...

• Improve code reading website
• Complete consts in asm8
• Clean up the symbol linking in asm8 a little bit
• Package building system that tracks timestamps
• Online filesystem and online editing
• Code formatter
