                Please write an AIDL program to generate a fish

Sure, let's generate an AIDL program to create a fish shape. We'll start by defining the structures for the fish body, tail, fins, and an eye. Then, we'll add the necessary constraints and geometry to describe the overall shape.

I'll guide you through each step:

1. Define the structures and their hierarchical relationships.
2. Add constraints between the structures.
3. Add geometry for each structure.

Let's start:

### Step 1: Define the structures

We'll create a `Solid` structure for the body of the fish and add substructures for the fins, tail, and eye.

```python
from AIDL import *

def fish(
        body_length: float = 5 * inches,
        body_height: float = 2 * inches,
        tail_width: float = 1.5 * inches,
        tail_height: float = 1.5 * inches,
        fin_width: float = 1 * inch,
        fin_height: float = 0.5 * inch,
        eye_radius: float = 0.15 * inch
):
    # Define the main structure: the fish body
    fish = Solid()

    # Define substructures for tail, fins, and eye
    body = Solid()
    tail = Solid()
    fin1 = Solid()
    fin2 = Solid()
    eye = Solid(shift=(1 * inch, 0.5 * inch))  # Shift the eye position

    # Add substructures to the main fish structure
    fish.body = body
    fish.tail = tail
    fish.fin1 = fin1
    fish.fin2 = fin2
    fish.eye = eye

    return fish
```

### Step 2: Add constraints between the structures

We'll position the tail to be at the right end of the body, and position the fins symmetrically on top and bottom of the body. The eye will be positioned near the left end of the body.

```python
def fish(
        body_length: float = 5 * inches,
        body_height: float = 2 * inches,
        tail_width: float = 1.5 * inches,
        tail_height: float = 1.5 * inches,
        fin_width: float = 1 * inch,
        fin_height: float = 0.5 * inch,
        eye_radius: float = 0.15 * inch
):
    fish = Solid()
    body = Solid()
    tail = Solid()
    fin1 = Solid()
    fin2 = Solid()
    eye = Solid(shift=(1 * inch, 0.5 * inch))

    fish.body = body
    fish.tail = tail
    fish.fin1 = fin1
    fish.fin2 = fin2
    fish.eye = eye

    # Constraints to position tail at the right end of the body
    body.AddConstraint(body.bb.right == tail.bb.left)
    body.AddConstraint(body.bb.vertical_center == tail.bb.vertical_center)

    # Constraints to position fins symmetrically on top and bottom of body
    body.AddConstraint(body.bb.horizontal_center == fin1.bb.horizontal_center)
    body.AddConstraint(body.bb.horizontal_center == fin2.bb.horizontal_center)
    body.AddConstraint(body.bb.top == fin1.bb.bottom)
    body.AddConstraint(body.bb.bottom == fin2.bb.top)

    return fish
```

### Step 3: Add geometry for each structure

We'll add appropriate 2D geometry for the body, tail, fins, and eye.

```python
def fish(
        body_length: float = 5 * inches,
        body_height: float = 2 * inches,
        tail_width: float = 1.5 * inches,
        tail_height: float = 1.5 * inches,
        fin_width: float = 1 * inch,
        fin_height: float = 0.5 * inch,
        eye_radius: float = 0.15 * inch
):
    fish = Solid()
    body = Solid()
    tail = Solid()
    fin1 = Solid()
    fin2 = Solid()
    eye = Solid(shift=(1 * inch, 0.5 * inch))

    fish.body = body
    fish.tail = tail
    fish.fin1 = fin1
    fish.fin2 = fin2
    fish.eye = eye

    # Constraints to position tail at the right end of the body
    body.AddConstraint(body.bb.right == tail.bb.left)
    body.AddConstraint(body.bb.vertical_center == tail.bb.vertical_center)

    # Constraints to position fins symmetrically on top and bottom of body
    body.AddConstraint(body.bb.horizontal_center == fin1.bb.horizontal_center)
    body.AddConstraint(body.bb.horizontal_center == fin2.bb.horizontal_center)
    body.AddConstraint(body.bb.top == fin1.bb.bottom)
    body.AddConstraint(body.bb.bottom == fin2.bb.top)

    # Add geometry for the body
    body.shape = RoundedRectangle((0,0), body_length, body_height, body_height / 2)

    # Add geometry for the tail
    tail.shape = Triangle((0,0), tail_width, tail_height)
    tail.AddConstraint(tail.shape.left_corner.u == 0) # center the tail horizontally

    # Add geometry for the fins
    fin1.shape = Triangle((0,0), fin_width, fin_height)
    fin2.shape = Triangle((0,0), fin_width, fin_height)

    # Add geometry for the eye
    eye.shape = Circle((0,0), eye_radius)

    return fish


with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

This program creates a simple fish shape with a body, a tail, two fins, and an eye. The tail, fins, and eye are positioned relative to the body using constraints. Each part of the fish is defined using appropriate geometric shapes.

Let me know if you need any adjustments or additional features for the fish model!

NameError: name 'inches' is not defined


It looks like we need to import and define some utility constants like `inch` and `inches` before using them in the function. Let's define these and ensure we have them available before we proceed.

I'll add the necessary definitions and constants at the beginning of the script. Here's the updated version of the fish AIDL program:

```python
from AIDL import *

# Define utility constants
inch = 25.4 * mm  # 1 inch equals 25.4 millimeters
inches = inch  # Alias for inches


def fish(
        body_length: float = 5 * inches,
        body_height: float = 2 * inches,
        tail_width: float = 1.5 * inches,
        tail_height: float = 1.5 * inches,
        fin_width: float = 1 * inch,
        fin_height: float = 0.5 * inch,
        eye_radius: float = 0.15 * inch
):
    fish = Solid()
    body = Solid()
    tail = Solid()
    fin1 = Solid()
    fin2 = Solid()
    eye = Solid(shift=(1 * inch, 0.5 * inch))

    fish.body = body
    fish.tail = tail
    fish.fin1 = fin1
    fish.fin2 = fin2
    fish.eye = eye

    # Constraints to position tail at the right end of the body
    body.AddConstraint(body.bb.right == tail.bb.left)
    body.AddConstraint(body.bb.vertical_center == tail.bb.vertical_center)

    # Constraints to position fins symmetrically on top and bottom of body
    body.AddConstraint(body.bb.horizontal_center == fin1.bb.horizontal_center)
    body.AddConstraint(body.bb.horizontal_center == fin2.bb.horizontal_center)
    body.AddConstraint(body.bb.top == fin1.bb.bottom)
    body.AddConstraint(body.bb.bottom == fin2.bb.top)

    # Add geometry for the body
    body.shape = RoundedRectangle((0, 0), body_length, body_height, body_height / 2)

    # Add geometry for the tail
    tail.shape = Triangle((0, 0), tail_width, tail_height)
    tail.AddConstraint(tail.shape.left_corner.u == 0)  # center the tail horizontally

    # Add geometry for the fins
    fin1.shape = Triangle((0, 0), fin_width, fin_height)
    fin2.shape = Triangle((0, 0), fin_width, fin_height)

    # Add geometry for the eye
    eye.shape = Circle((0, 0), eye_radius)

    return fish


with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

This should properly define the units and avoid the `NameError` for `inches`. If you have any further issues, feel free to let me know!

    raise NonLocalContext(context, self._structure)
AIDL.feedback.NonLocalContext: .tail referenced from .body.


The feedback indicates that there's an issue with referencing the bounding box (`bb`) of the `tail` directly within the `body` context. A structure should not reference the geometry or bounding box properties of sibling structures directly within constraints.

To avoid this problem, we should set constraints at a higher level in the hierarchical tree, ensuring they're in the correct context. In this case, instead of referencing `tail.bb` directly in `body`, we can add the constraints on the `fish` level which is their common parent.

Let's update the constraints to reference them correctly at the `fish` level.

```python
from AIDL import *

# Define utility constants
inch = 25.4 * mm  # 1 inch equals 25.4 millimeters
inches = inch  # Alias for inches

def fish(
        body_length: float = 5 * inches,
        body_height: float = 2 * inches,
        tail_width: float = 1.5 * inches,
        tail_height: float = 1.5 * inches,
        fin_width: float = 1 * inch,
        fin_height: float = 0.5 * inch,
        eye_radius: float = 0.15 * inch
):
    fish = Solid()
    body = Solid()
    tail = Solid()
    fin1 = Solid()
    fin2 = Solid()
    eye = Solid(shift=(1 * inch, 0.5 * inch))

    fish.body = body
    fish.tail = tail
    fish.fin1 = fin1
    fish.fin2 = fin2
    fish.eye = eye

    # Constraints to position tail, fins, and eye relative to body
    fish.AddConstraint(body.bb.right == tail.bb.left)
    fish.AddConstraint(body.bb.vertical_center == tail.bb.vertical_center)
    fish.AddConstraint(body.bb.horizontal_center == fin1.bb.horizontal_center)
    fish.AddConstraint(body.bb.horizontal_center == fin2.bb.horizontal_center)
    fish.AddConstraint(body.bb.top == fin1.bb.bottom)
    fish.AddConstraint(body.bb.bottom == fin2.bb.top)

    # Add geometry for the body
    body.shape = RoundedRectangle((0, 0), body_length, body_height, body_height / 2)

    # Add geometry for the tail
    tail.shape = Triangle((0, 0), tail_width, tail_height)
    tail.AddConstraint(tail.shape.right_corner.u == 0)  # Align the tail's apex with the body's vertical center

    # Add geometry for the fins
    fin1.shape = Triangle((0, 0), fin_width, fin_height)
    fin2.shape = Triangle((0, 0), fin_width, fin_height)

    # Add geometry for the eye
    eye.shape = Circle((0, 0), eye_radius)

    return fish


with AIDL_2D:
    model = fish()
print(model.Solve())
model.Render()
```

In this version, we have updated the constraints to be added at the `fish` level, ensuring all references to sibling structures are correctly scoped within their common parent structure. This should resolve the `NonLocalContext` error.
