ezc

https://github.com/g-w1/ezc/workflows/Rust/badge.svg

Compiler for ez.

This is for an independent study in school.

Goals

  • To learn a lot
  • ez should resemble english
  • Use only rust standard library
  • Write a (minimal) working compiler. probably only u64 but maybe arrays
  • Write a (minimal) standard library for ez in another language (zig, rust, c, asm, ..)

Instructions

To run just do ezc file use -g flag for debug info (it will generate a out.asm file). then you can open in gdb or lldb

To get the standard library pass -stdlib-path /path/to/stdlib to the compiler. To compile the standard library, go into the lib directory in this compiler. Then run zig build in that directory and find the library in zig-cache/lib/libstd.a. You will probably need pretty close to master branch zig. You can find that here: https://ziglang.org/download/.

To test the code: cargo test To test the generated code you can do cd tests; ./test.sh. Note: this requires gcc.

Dependencies:

  • Zig (master). NOTE: If you want to build without zig run HAS_NO_ZIG=1 cargo ...(whatever command you want). This may be useful if you are on a system without zig or want to provide your own standard library.
  • nasm
  • cargo
  • gcc (only for testing)
