core/ndstrides: implement subscript assignment 
Overlapping is not handled. Currently it has undefined behavior.
 2024-08-30 14:54:53 +08:00
lyken b22f2bc76c
core/ndstrides: add more ScalarOrNDArray and NDArrayObject utils 2024-08-30 14:52:57 +08:00
lyken b9e837109b
core/ndstrides: implement np_transpose() (no axes argument) 
The IRRT implementation knows how to handle axes. But the argument is
not in NAC3 yet.
 2024-08-30 14:50:48 +08:00
lyken d32268fb5d
core/ndstrides: implement broadcasting & np_broadcast_to() 2024-08-30 14:45:43 +08:00

core: categorize np_{transpose,reshape} as 'view functions' 2024-08-30 14:41:54 +08:00
lyken d2072d9248
core/ndstrides: implement np_size() 2024-08-30 14:41:00 +08:00
lyken be19165ead
core/ndstrides: implement np_shape() and np_strides() 
These functions are not important, but they are handy for debugging.

`np.strides()` is not an actual NumPy function, but `ndarray.strides` is used.
 2024-08-30 14:41:00 +08:00
lyken ee58cf3fc3
core/ndstrides: implement ndarray.fill() and .copy() 2024-08-30 14:41:00 +08:00
lyken 8fe8ccf200
core/ndstrides: implement np_identity() and np_eye() 2024-08-30 14:41:00 +08:00
lyken d222236492
core/ndstrides: implement np_array() 
It also checks for inconsistent dimensions if the input is a list.
e.g., rejecting `[[1.0, 2.0], [3.0]]`.

However, currently only `np_array(<input>, copy=False)` and `np_array(<input>, copy=True)` are supported. In NumPy, copy could be false, true, or None. Right now, NAC3's `np_array(<input>, copy=False)` behaves like NumPy's `np.array(<input>, copy=None)`.
 2024-08-30 14:40:15 +08:00
lyken 13715dbda9
core/irrt: add List 
Needed for implementing np_array()
 2024-08-30 14:20:19 +08:00

core/ndstrides: add NDArrayObject::atleast_nd 2024-08-30 14:18:34 +08:00
lyken 6edc3f895b
core/ndstrides: add NDArrayObject::make_copy 2024-08-30 14:18:17 +08:00
lyken a40cdde8d2
core/ndstrides: implement ndarray indexing 
The functionality for `...` and `np.newaxis` is there in IRRT, but there
is no implementation of them for @kernel Python expressions because of
#486.
 2024-08-30 14:12:54 +08:00
lyken 853fa39537
core/irrt: rename NDIndex to NDIndexInt 
Unfortunately the name `NDIndex` is used in later commits. Renaming this
typedef to `NDIndexInt` to avoid amending. `NDIndexInt` will be removed
anyway when ndarray strides is completed.
 2024-08-30 14:00:19 +08:00
lyken b6a1880226
core/irrt: add Slice and Range 
Needed for implementing general ndarray indexing.

Currently IRRT slice and range have nothing to do with NAC3's slice
and range. The IRRT slice and range are currently there to implement
ndarray specific features. However, in the future their definitions may
be used to replace that of NAC3's. (NAC3's range is a [i32 x 3], IRRT's
range is a proper struct. NAC3 does not have a slice struct).

/// Derives an implementation of `codegen::types::structure::StructFields`.

/// `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;
