-# NAC3
-NAC3 is a major, backward-incompatible rewrite of the compiler for the [ARTIQ](https://m-labs.hk/artiq) physics experiment control and data acquisition system. It features greatly improved compilation speeds, a much better type system, and more predictable and transparent operation.
-
-NAC3 has a modular design and its applicability reaches beyond ARTIQ. The ``nac3core`` module does not contain anything specific to ARTIQ, and can be used in any project that requires compiling Python to machine code.
-
-**WARNING: NAC3 is currently experimental software and several important features are not implemented yet.**
-
-## Packaging
-
-NAC3 is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.8+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``).
-
-## Try NAC3
-
-### Linux
-
-After setting up Nix as above, use ``nix shell git+https://github.com/m-labs/artiq.git?ref=nac3`` to get a shell with the NAC3 version of ARTIQ. See the ``examples`` directory in ARTIQ (``nac3`` Git branch) for some samples of NAC3 kernel code.
-
-### Windows
-
-Install [MSYS2](https://www.msys2.org/), and open "MSYS2 CLANG64". Edit ``/etc/pacman.conf`` to add:
-```
-[artiq]
-SigLevel = Optional TrustAll
-Server = https://msys2.m-labs.hk/artiq-nac3
-```
-
-Then run the following commands:
-```
-pacman -Syu
-pacman -S mingw-w64-clang-x86_64-artiq
-```
-
-## For developers
 
 This repository contains:
-- ``nac3ast``: Python abstract syntax tree definition (based on RustPython).
+- nac3core: Core compiler library, containing type-checking, static analysis (in
-- ``nac3parser``: Python parser (based on RustPython).
+    the future) and code generation.
-- ``nac3core``: Core compiler library, containing type-checking and code generation.
+- nac3embedded: Integration with CPython runtime.
-- ``nac3standalone``: Standalone compiler tool (core language only).
+- nac3standalone: Standalone compiler tool.
-- ``nac3ld``: Minimalist RISC-V and ARM linker.
-- ``nac3artiq``: Integration with ARTIQ and implementation of ARTIQ-specific extensions to the core language.
-- ``runkernel``: Simple program that runs compiled ARTIQ kernels on the host and displays RTIO operations. Useful for testing without hardware.
 
-Use ``nix develop`` in this repository to enter a development shell.
+The core compiler would know nothing about symbol resolution, host variables
-If you are using a different shell than bash you can use e.g. ``nix develop --command fish``.
+etc. The nac3embedded/nac3standalone library would provide (implement) the
+symbol resolver to the core compiler for resolving the type and value for
+unknown symbols. The core compiler would only type check classes and functions
+requested by the nac3embedded/nac3standalone lib (the API should allow the
+caller to specify which methods should be compiled). After type checking, the
+compiler would analyse the set of functions/classes that are used and perform
+code generation.
 
-Build NAC3 with ``cargo build --release``. See the demonstrations in ``nac3artiq`` and ``nac3standalone``.
+value could be integer values, boolean values, bytes (for memcpy), function ID
+(full name + concrete type)
 
-### Pre-Commit Hooks
+## Current Plan
+
+Type checking:
+
+- [x] Basic interface for symbol resolver.
+- [x] Track location information in context object (for diagnostics).
+- [ ] Refactor old expression and statement type inference code. (anto)
+- [ ] Error diagnostics utilities. (pca)
+- [ ] Move tests to external files, write scripts for testing. (pca)
+- [ ] Implement function type checking (instantiate bounded type parameters),
+    loop unrolling, type inference for lists with virtual objects. (pca)
 
-You are strongly recommended to use the provided pre-commit hooks to automatically reformat files and check for non-optimal Rust practices using Clippy. Run `pre-commit install` to install the hook and `pre-commit` will automatically run `cargo fmt` and `cargo clippy` for you.
 
-Several things to note:
 
-- If `cargo fmt` or `cargo clippy` returns an error, the pre-commit hook will fail. You should fix all errors before trying to commit again.
-- If `cargo fmt` reformats some files, the pre-commit hook will also fail. You should review the changes and, if satisfied, try to commit again.

-/// Derives an implementation of `codegen::types::structure::StructFields`.
-///
-/// The benefit of using `#[derive(StructFields)]` is that all index- or order-dependent logic required by
-/// `impl StructFields` is automatically generated by this implementation, including the field index as required by
-/// `StructField::new` and the fields as returned by `StructFields::to_vec`.
-///
-/// # Prerequisites
-///
-/// In order to derive from [`StructFields`], you must implement (or derive) [`Eq`] and [`Copy`] as required by
-/// `StructFields`.
-///
-/// Moreover, `#[derive(StructFields)]` can only be used for `struct`s with named fields, and may only contain fields
-/// with either `StructField` or [`PhantomData`] types.
-///
-/// # Attributes for [`StructFields`]
-///
-/// Each `StructField` field must be declared with the `#[value_type(...)]` attribute. The argument of `value_type`
-/// accepts one of the following:
-///
-/// - An expression returning an instance of `inkwell::types::BasicType` (with or without the receiver `ctx`/`context`).
-/// For example, `context.i8_type()`, `ctx.i8_type()`, and `i8_type()` all refer to `i8`.
-/// - The reserved identifiers `usize` and `size_t` referring to an `inkwell::types::IntType` of the platform-dependent
-/// integer size. `usize` and `size_t` can also be used as the receiver to other method calls, e.g.
-/// `usize.array_type(3)`.
-///
-/// # Example
-///
-/// The following is an example of an LLVM slice implemented using `#[derive(StructFields)]`.
-///
-/// ```rust,ignore
-/// use nac3core::{
-///     codegen::types::structure::StructField,
-///     inkwell::{
-///         values::{IntValue, PointerValue},
-///         AddressSpace,
-///     },
-/// };
-/// use nac3core_derive::StructFields;
-///
-/// // All classes that implement StructFields must also implement Eq and Copy
-/// #[derive(PartialEq, Eq, Clone, Copy, StructFields)]
-/// pub struct SliceValue<'ctx> {
-///     // Declares ptr have a value type of i8*
-///     //
-///     // Can also be written as `ctx.i8_type().ptr_type(...)` or `context.i8_type().ptr_type(...)`
-///     #[value_type(i8_type().ptr_type(AddressSpace::default()))]
-///     ptr: StructField<'ctx, PointerValue<'ctx>>,
-///
-///     // Declares len have a value type of usize, depending on the target compilation platform
-///     #[value_type(usize)]
-///     len: StructField<'ctx, IntValue<'ctx>>,
-/// }

-//! This module contains abstraction over all intrinsic composite types of NAC3.
-//!
-//! # `raw_alloca` vs `alloca` vs `construct`
-//!
-//! There are three ways of creating a new object instance using the abstractions provided by this
-//! module.
-//!
-//! - `raw_alloca`: Allocates the object on the stack, returning an instance of
-//!   [`impl BasicValue`][inkwell::values::BasicValue]. This is similar to a `malloc` expression in
-//!   C++ but the object is allocated on the stack.
-//! - `alloca`: Similar to `raw_alloca`, but also wraps the allocated object with
-//!   [`<Self as ProxyType<'ctx>>::Value`][ProxyValue], and returns the wrapped object. The returned
-//!   object will not initialize any value or fields. This is similar to a type-safe `malloc`
-//!   expression in C++ but the object is allocated on the stack.
-//! - `construct`: Similar to `alloca`, but performs some initialization on the value or fields of
-//!   the returned object. This is similar to a `new` expression in C++ but the object is allocated
-//!   on the stack.
