zlox, a clox rewrite in Zig.

While reading Crafting Interpreters, after having rewrote the interpreter part in Rust (see rs-lox), I'm now attempting to write the bytecode compiler in Zig.

14 - Chunks of Bytecode
15 - A Virtual Machine
16 - Scanning on Demand
17 - Compiling Expressions
18 - Types of Values
19 - Strings
20 - Hash Tables
21 - Global Variables
22 - Local Variables
23 - Jumping Back and Forth
24 - Calls and Functions
25 - Closures
26 - Garbage Collection
27 - Classes and Instances
28 - Method and Initializers
29 - Superclasses
30 - Optimization

Build & run

There is a justfile to help building & running:

$ just build
$ ls -l zig-out/bin/zlox
-rwxr-xr-x 1 mycroft mycroft 2823296 Aug 25 15:36 zig-out/bin/zlox

$ just run
zig build run
> 2*3 + 3*4
== code ==
0000    1      OP_CONSTANT    0 '2'
0002    |      OP_CONSTANT    1 '3'
0004    |      OP_MULTIPLY
0005    |      OP_CONSTANT    2 '3'
0007    |      OP_CONSTANT    3 '4'
0009    |      OP_MULTIPLY
000a    |           OP_ADD
== end of code ==

0000    1      OP_CONSTANT    0 '2'
                                [ 2 ]
0002    |      OP_CONSTANT    1 '3'
                                [ 2 ][ 3 ]
0004    |      OP_MULTIPLY
                                [ 6 ]
0005    |      OP_CONSTANT    2 '3'
                                [ 6 ][ 3 ]

                                [ 6 ][ 12 ]
