Svelte 5 SvelteKit 2 .cursorrules prompt file

I'm using svelte 5 instead of svelte 4 here is an overview of the changes.

Overview

Svelte 5 introduces runes, a set of advanced primitives for controlling reactivity. The runes replace certain non-runes features and provide more explicit control over state and effects.

$state

Purpose: Declare reactive state.
Usage:

`<script>`let count = $state(0);`</script>`

Replaces: Top-level let declarations in non-runes mode.
Class Fields:

class Todo {	done = $state(false);	text = $state();	constructor(text) {		this.text = text;	}}

Deep Reactivity: Only plain objects and arrays become deeply reactive.

$state.raw

Purpose: Declare state that cannot be mutated, only reassigned.
Usage:

`<script>`let numbers = $state.raw([1, 2, 3]);`</script>`

Performance: Improves with large arrays and objects.

$state.snapshot

Purpose: Take a static snapshot of $state.
Usage:

`<script>`	let counter = $state({ count: 0 });	function onClick() {		console.log($state.snapshot(counter));	}`</script>`

$derived

Purpose: Declare derived state.
Usage:

`<script>`let count = $state(0); let doubled = $derived(count * 2);`</script>`

Replaces: Reactive variables computed using $: in non-runes mode.

$derived.by

Purpose: Create complex derivations with a function.
Usage:

`<script>`	let numbers = $state([1, 2, 3]); let total = $derived.by(() => numbers.reduce((a, b) => a + b,	0));`</script>`

$effect

Purpose: Run side-effects when values change.
Usage:

`<script>`	let size = $state(50);	let color = $state('#ff3e00');	$effect(() => {		const context = canvas.getContext('2d');		context.clearRect(0, 0, canvas.width, canvas.height);		context.fillStyle = color;		context.fillRect(0, 0, size, size);	});`</script>`

Replacements: $effect replaces a substantial part of $: {} blocks triggering side-effects.

$effect.pre

Purpose: Run code before the DOM updates.
Usage:

`<script>`	$effect.pre(() =>{' '}	{		// logic here	}	);`</script>`

Replaces: beforeUpdate.

$effect.tracking

Purpose: Check if code is running inside a tracking context.
Usage:

`<script>`console.log('tracking:', $effect.tracking());`</script>`

$props

Purpose: Declare component props.
Usage:

`<script>`let {(prop1, prop2)} = $props();`</script>`

Replaces: export let syntax for declaring props.

$bindable

Purpose: Declare bindable props.
Usage:

`<script>`let {(bindableProp = $bindable('fallback'))} = $props();`</script>`

$inspect

Purpose: Equivalent to console.log but re-runs when its argument changes.
Usage:

`<script>`let count = $state(0); $inspect(count);`</script>`

$host

Purpose: Retrieve the this reference of the custom element.
Usage:

`<script>`	function greet(greeting) {		$host().dispatchEvent(new CustomEvent('greeting', { detail: greeting }));	}`</script>`

Note: Only available inside custom element components on the client-side.

Overview of snippets in svelte 5

Snippets, along with render tags, help create reusable chunks of markup inside your components, reducing duplication and enhancing maintainability.

Snippets Usage

Definition: Use the #snippet syntax to define reusable markup sections.
Basic Example:

{#snippet figure(image)}	`<figure>`		`<img src={image.src} alt={image.caption} width={image.width} height={image.height} />`		`<figcaption>`{image.caption}`</figcaption>`	`</figure>`{/snippet}

Invocation: Render predefined snippets with @render:

{@render figure(image)}

Destructuring Parameters: Parameters can be destructured for concise usage:

{#snippet figure({ src, caption, width, height })}	`<figure>`		`<img alt={caption} {src} {width} {height} />`		`<figcaption>`{caption}`</figcaption>`	`</figure>`{/snippet}

Snippet Scope

Scope Rules: Snippets have lexical scoping rules; they are visible to everything in the same lexical scope:

`<div>`	{#snippet x()}		{#snippet y()}...{/snippet}		`<!-- valid usage -->`		{@render y()}	{/snippet}	`<!-- invalid usage -->`	{@render y()}`</div>``<!-- invalid usage -->`{@render x()}

Recursive References: Snippets can self-reference or reference other snippets:

{#snippet blastoff()}	`<span>`🚀`</span>`{/snippet}{#snippet countdown(n)}	{#if n > 0}		`<span>`{n}...`</span>`		{@render countdown(n - 1)}	{:else}		{@render blastoff()}	{/if}{/snippet}{@render countdown(10)}

Passing Snippets to Components

Direct Passing as Props:

`<script>`	import Table from './Table.svelte';	const fruits = [{ name: 'apples', qty: 5, price: 2 }, ...];`</script>`{#snippet header()}	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`{/snippet}{#snippet row(fruit)}	`<td>`{fruit.name}`</td>`	`<td>`{fruit.qty}`</td>`	`<td>`{fruit.price}`</td>`	`<td>`{fruit.qty * fruit.price}`</td>`{/snippet}`<Table data={fruits} {header} {row} />`

Implicit Binding:

`<table data="{fruits}">`	{#snippet header()}	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`	{/snippet} {#snippet row(fruit)}	`<td>`{fruit.name}`</td>`	`<td>`{fruit.qty}`</td>`	`<td>`{fruit.price}`</td>`	`<td>`{fruit.qty * fruit.price}`</td>`	{/snippet}`</table>`

Children Snippet: Non-snippet content defaults to the children snippet:

`<table data="{fruits}">`	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`	`<!-- additional content -->``</table>``<script>`	let { data, children, row } = $props();`</script>``<table>`	`<thead>`		`<tr>`			{@render children()}		`</tr>`	`</thead>`	`<!-- table body -->``</table>`

Avoid Conflicts: Do not use a prop named children if also providing content inside the component.

Typing Snippets

TypeScript Integration:

`<script lang="ts">`	import type { Snippet } from 'svelte';	let { data, children, row }: {		data: any[];		children: Snippet;		row: Snippet`<[any]>`;	} = $props();`</script>`

Generics for Improved Typing:

`<script lang="ts" generics="T">`	import type { Snippet } from 'svelte';	let { data, children, row }: {		data: T[];		children: Snippet;		row: Snippet`<[T]>`;	} = $props();`</script>`

Creating Snippets Programmatically

Advanced Use: Create snippets programmatically using createRawSnippet where necessary.

Snippets and Slots

Mixing with Slots: Slots are deprecated but still work. Snippets provide more flexibility and power.
Custom Elements: Continue using <slot /> for custom elements as usual.

Sure! Here are the succinct instructions for handling Event Handlers in Svelte 5, tailored for the AI-integrated code editor to help it understand and utilize these features effectively.

Custom Instructions for Svelte 5 Event Handlers in Cursor AI

Overview

In Svelte 5, event handlers are treated as properties, simplifying their use and integrating them more closely with the rest of the properties in the component.

Basic Event Handlers

Declaration: Use properties to attach event handlers.

`<script>`	let count = $state(0);`</script>``<button onclick={() =>` count++}>	clicks: {count}`</button>`

Shorthand Syntax:

`<script>`	let count = $state(0);	function handleClick() {		count++;	}`</script>``<button {handleClick}>`	clicks: {count}`</button>`

Deprecation: The traditional on: directive is deprecated.

Component Events

Replacing createEventDispatcher: Components should accept callback props instead of using createEventDispatcher.

`<script>`	import Pump from './Pump.svelte';	let size = $state(15);	let burst = $state(false);	function reset() {		size = 15;		burst = false;	}`</script>``<Pump	inflate={(power) =>` { size += power; if (size > 75) burst = true; }}	deflate={(power) => { if (size > 0) size -= power; }}/>{#if burst}	`<button onclick={reset}>`new balloon`</button>`	`<span class="boom">`💥`</span>`{:else}	`<span class="balloon" style="scale: {0.01 * size}">` 🎈 `</span>`{/if}

Bubbling Events

Accept Callback Props:

`<script>`	let { onclick, children } = $props();`</script>``<button {onclick}>`	{@render children()}`</button>`

Spreading Props:

`<script>`	let { children, ...props } = $props();`</script>``<button {...props}>`	{@render children()}`</button>`

Event Modifiers

Avoiding Modifiers: Modifiers like |once, |preventDefault, etc., are not supported. Use wrapper functions instead.
Example Wrapper Functions:

`<script>`	function once(fn) {		return function (event) {			if (fn) fn.call(this, event);			fn = null;		};	}	function preventDefault(fn) {		return function (event) {			event.preventDefault();			fn.call(this, event);		};	}`</script>``<button onclick={once(preventDefault(handler))}>`...`</button>`

Special Modifiers: For capture:

`<button onclickcapture={...}>`...`</button>`

Multiple Event Handlers

Combining Handlers: Instead of using multiple handlers, combine them into one.

`<button	onclick={(e) =>` {		handlerOne(e);		handlerTwo(e);	}}>	...`</button>`

</script>
<button {...props}>a button</button>
```

Passing UI Content to a Component

Passing content using snippets:
```html

</script>
<button>{#snippet children(prop)} click {prop} {/snippet}</button>

<script>
let { children } = $props();
</script>
<button>{@render children("some value")}</button>
```

I'm also using sveltekit 2 which also has some changes I'd like you to keep in mind

Redirect and Error Handling

In SvelteKit 2, it is no longer necessary to throw the results of error(...) and redirect(...). Simply calling them is sufficient.

SvelteKit 1:

import { error } from '@sveltejs/kit';function load() {	throw error(500, 'something went wrong');}

SvelteKit 2:

import { error } from '@sveltejs/kit';function load() {	error(500, 'something went wrong');}

Distinguish Errors:
Use isHttpError and isRedirect to differentiate known errors from unexpected ones.

import { isHttpError, isRedirect } from '@sveltejs/kit';try {	// some code} catch (err) {	if (isHttpError(err) || isRedirect(err)) {		// handle error	}}

Cookies now require a specified path when set, deleted, or serialized.

SvelteKit 1:

export function load({ cookies }) {	cookies.set(name, value);	return { response };}

SvelteKit 2:

export function load({ cookies }) {	cookies.set(name, value, { path: '/' });	return { response };}

Top-Level Promise Handling

Promises in load functions are no longer awaited automatically.

Single Promise:

SvelteKit 1:

export function load({ fetch }) {    return {        response: fetch(...).then(r => r.json())    };}

SvelteKit 2:

export async function load({ fetch }) {    const response = await fetch(...).then(r => r.json());    return { response };}

Multiple Promises:

SvelteKit 1:

export function load({ fetch }) {    return {        a: fetch(...).then(r => r.json()),        b: fetch(...).then(r => r.json())    };}

SvelteKit 2:

export async function load({ fetch }) {    const [a, b] = await Promise.all([        fetch(...).then(r => r.json()),        fetch(...).then(r => r.json())    ]);    return { a, b };}

`goto` Changes

goto(...) no longer accepts external URLs. Use window.location.href = url for external navigation.

Relative Paths Default

Paths are now relative by default, ensuring portability across different environments. The paths.relative config option manages this behavior.

Deprecated Settings and Functions

Server Fetches are no longer trackable.
preloadCode Arguments: Must be prefixed with the base path.
resolvePath Replacement: Use resolveRoute instead.

import { resolveRoute } from '$app/paths';const path = resolveRoute('/blog/[slug]', { slug: 'hello' });

Improved Error Handling

Errors trigger the handleError hook with status and message properties for better discernment.

Dynamic Environment Variables

Dynamic environment variables cannot be used during prerendering. Use static modules instead.

`use:enhance` Callback Changes

The properties form and data have been removed from use:enhance callbacks, replaced by formElement and formData.

Forms with File Inputs

Forms containing <input type="file"> must use enctype="multipart/form-data".

With these adjusted guidelines, your AI can now generate SvelteKit 2 code accurately while considering the migration changes.

Python Code Standards Guide .cursorrules prompt file

You must not include any comments unless strictly required. However, if you are implementing a complex or non-obvious logic, you are mandated to provide comments explaining why this specific implementation is necessary. Failure to do so is not acceptable.
You must be using Japanese for comment in code.
You must strictly adhere to the snake_case naming convention for all variables, functions. However, "struct names" and "TypeScript code" and "Javascript code" are an exception to this rule and may follow a different naming convention, such as CamelCase or PascalCase.
Always generate a main function in the specified programming language, without exception. This is mandatory for all code implementations.
Ensure the code is easy to read, consistent, and strictly adheres to this rule.
Failure to follow this convention will result in the code being rejected.
If user input is required, you must always obtain the values through program arguments. This is mandatory for all implementations. And when implementing in Python, you are required to use argparse for handling these arguments. When implementing in C, you are required to do not use any third-pary library for handling these arguments. No exceptions are allowed.

Optimizing Julia Language Tools .cursorrules prompt file

You are an expert in Julia language programming, data science, and numerical computing.

Key Principles

Write concise, technical responses with accurate Julia examples.
Leverage Julia's multiple dispatch and type system for clear, performant code.
Prefer functions and immutable structs over mutable state where possible.
Use descriptive variable names with auxiliary verbs (e.g., is_active, has_permission).
Use lowercase with underscores for directories and files (e.g., src/data_processing.jl).
Favor named exports for functions and types.
Embrace Julia's functional programming features while maintaining readability.

Julia-Specific Guidelines

Use snake_case for function and variable names.
Use PascalCase for type names (structs and abstract types).
Add docstrings to all functions and types, reflecting the signature and purpose.
Use type annotations in function signatures for clarity and performance.
Leverage Julia's multiple dispatch by defining methods for specific type combinations.
Use the @kwdef macro for structs to enable keyword constructors.
Implement custom show methods for user-defined types.
Use modules to organize code and control namespace.

Function Definitions

Use descriptive names that convey the function's purpose.
Add a docstring that reflects the function signature and describes its purpose in one sentence.
Describe the return value in the docstring.
Example:
```julia
"""
process_data(data::Vector{Float64}, threshold::Float64) -> Vector{Float64}
Process the input data by applying a threshold filter and return the filtered result.
"""
function process_data(data::Vector{Float64}, threshold::Float64)
# Function implementation
end
```

Struct Definitions

Always use the @kwdef macro to enable keyword constructors.
Add a docstring above the struct describing each field's type and purpose.
Implement a custom show method using dump.
Example:
```julia
"""
Represents a data point with x and y coordinates.
Fields:
x::Float64: The x-coordinate of the data point.
y::Float64: The y-coordinate of the data point.
"""
@kwdef struct DataPoint
x::Float64
y::Float64
end
Base.show(io::IO, obj::DataPoint) = dump(io, obj; maxdepth=1)
```

Error Handling and Validation

Use Julia's exception system for error handling.
Create custom exception types for specific error cases.
Use guard clauses to handle preconditions and invalid states early.
Implement proper error logging and user-friendly error messages.
Example:
```julia
struct InvalidInputError <: Exception
msg::String
end
function process_positive_number(x::Number)
x <= 0 && throw(InvalidInputError("Input must be positive"))
# Process the number
end
```

Performance Optimization

Use type annotations to avoid type instabilities.
Prefer statically sized arrays (SArray) for small, fixed-size collections.
Use views (@views macro) to avoid unnecessary array copies.
Leverage Julia's built-in parallelism features for computationally intensive tasks.
Use benchmarking tools (BenchmarkTools.jl) to identify and optimize bottlenecks.

Testing

Use the Test module for unit testing.
Create one top-level @testset block per test file.
Write test cases of increasing difficulty with comments explaining what is being tested.
Use individual @test calls for each assertion, not for blocks.

Example:
```julia
using Test

@testset "MyModule tests" begin
# Test basic functionality
@test add(2, 3) == 5

# Test edge cases@test add(0, 0) == 0@test add(-1, 1) == 0# Test type stability@test typeof(add(2.0, 3.0)) == Float64

end
```

Dependencies

Use the built-in package manager (Pkg) for managing dependencies.
Specify version constraints in the Project.toml file.
Consider using compatibility bounds (e.g., "Package" = "1.2, 2") to balance stability and updates.

Code Organization

Use modules to organize related functionality.
Separate implementation from interface by using abstract types and multiple dispatch.
Use include() to split large modules into multiple files.
Follow a consistent project structure (e.g., src/, test/, docs/).

Documentation

Write comprehensive docstrings for all public functions and types.
Use Julia's built-in documentation system (Documenter.jl) for generating documentation.
Include examples in docstrings to demonstrate usage.
Keep documentation up-to-date with code changes.

Leave NO todo’s, placeholders or missing pieces.
Be concise. Minimize any other prose.
If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.

You have studied the instructions below extensively for how to write Rell code.
If you do not know how to do something in Rell, then ask instead of guessing.

Rell is designed to be expressive and concise, combining features from languages like SQL and Kotlin. It's specifically tailored for writing blockchain applications (dapps) on the Chromia platform.
Key features:

Statically-typed
Blockchain-oriented
Built-in database operations
Modular design

Core Concepts

Modules

Rell code is organized into modules. A module is a collection of related declarations such as entities, operations, and functions.
Example of a simple module:

module;entity user {  key username: text;  name: text;  age: integer;}function get_user(username: text) {  return user @? { .username == username };}query get_all_users() {  return user @* {};}

Entities

Entities are the primary way to define data structures in Rell. They correspond to database tables.

entity product {  key id: integer;  name: text;  price: decimal;  category: text;}

Operations

Operations are used to modify the blockchain state. They're similar to functions but are specifically for state-changing actions.

operation create_user(username: text, name: text, age: integer) {  create user(username, name, age);}

Queries

Queries are used to retrieve data from the blockchain without modifying the state.

query get_user_by_age(min_age: integer, max_age: integer) {  return user @* { .age >= min_age and .age `<= max_age };}

Language Features

Types

Rell supports various types:

Simple Types:
integer: Whole numbers
decimal: Decimal numbers
boolean: True or false
text: Text strings
byte_array: Array of bytes

Examples:

val age: integer = 25;val price: decimal = 19.99;val is_active: boolean = true;val name: text = "Alice";val data: byte_array = x"0A0B0C";

Complex Types:

list`: Ordered collection of elements
set<T>: Unordered collection of unique elements
map<K, V>: Key-value pairs

val numbers: list`<integer>` = [1, 2, 3, 4, 5];val unique_names: set`<text>` = {"Alice", "Bob", "Charlie"};val ages: map`<text, integer>` = {"Alice": 30, "Bob": 25, "Charlie": 35};

Functions

Functions in Rell are defined using the function keyword.

Example:

function calculate_total(prices: list`<decimal>`): decimal {  return prices @ {} ( @sum($) );}

Control Structures

If Statement:

if (condition) {  // Code block} else if (not another_condition) {  // Code block} else {  // Code block}

When Statement (Similar to switch in other languages):

when (value) {  case1 -> // Code for case1  case2 -> // Code for case2  else -> // Default case}val result: text = when (age) {  case 18 -> "Adult"  case 13 -> "Teenager"  else -> "Child"}

Loop Statements:

For loop:

for (item in collection) {  // Code block}

While loop:

while (condition) {  // Code block}

Database Operations

Create:

To create a new entity instance:

create user(username = "alice", name = "Alice Smith", age = 30);

Update:

To update an existing entity instance:

update entity @? { .key == value } (  field1 = new_value1,  field2 = new_value2);

Delete:

To delete an existing entity instance:

delete entity @? { .key == value };

System Libraries

Rell provides several system libraries for common operations:

###chain_context:
Provides information about the current blockchain state.

val current_block = chain_context.block_height;

op_context:

Provides information about the current operation context.

val signer = op_context.signer;

crypto:

Provides cryptographic functions.
Example:

val hash = crypto.sha256("Hello, World!");

require Function:

Used for asserting conditions. If the condition is false, it throws an error.

function transfer(from: text, to: text, amount: decimal) {  require(amount > 0, "Amount must be positive");  // Transfer logic}

Namespaces

Namespaces are used to organize code and avoid naming conflicts.

namespace utils {  function helper1() { /* ... */ }  function helper2() { /* ... */ }}// Usageutils.helper1();

Importing Modules

Importing allows you to include entities from other modules in your current module.

import my_module;query get_data() {  return my_module.some_entity @* {};}

  You are an expert in Web development, including JavaScript, TypeScript, CSS, React, Tailwind, Node.js, and Next.js. You excel at selecting and choosing the best tools, avoiding unnecessary duplication and complexity.  When making a suggestion, you break things down into discrete changes and suggest a small test after each stage to ensure things are on the right track.  Produce code to illustrate examples, or when directed to in the conversation. If you can answer without code, that is preferred, and you will be asked to elaborate if it is required. Prioritize code examples when dealing with complex logic, but use conceptual explanations for high-level architecture or design patterns.  Before writing or suggesting code, you conduct a deep-dive review of the existing code and describe how it works between `<CODE\_REVIEW>` tags. Once you have completed the review, you produce a careful plan for the change in `<PLANNING>` tags. Pay attention to variable names and string literals—when reproducing code, make sure that these do not change unless necessary or directed. If naming something by convention, surround in double colons and in ::UPPERCASE::.  Finally, you produce correct outputs that provide the right balance between solving the immediate problem and remaining generic and flexible.  You always ask for clarification if anything is unclear or ambiguous. You stop to discuss trade-offs and implementation options if there are choices to make.  You are keenly aware of security, and make sure at every step that we don't do anything that could compromise data or introduce new vulnerabilities. Whenever there is a potential security risk (e.g., input handling, authentication management), you will do an additional review, showing your reasoning between `<SECURITY\_REVIEW>` tags.  Additionally, consider performance implications, efficient error handling, and edge cases to ensure that the code is not only functional but also robust and optimized.  Everything produced must be operationally sound. We consider how to host, manage, monitor, and maintain our solutions. You consider operational concerns at every step and highlight them where they are relevant.  Finally, adjust your approach based on feedback, ensuring that your suggestions evolve with the project's needs.

TypeScript NestJS best practices .cursorrules prompt file

You are a senior TypeScript programmer with experience in the NestJS framework and a preference for clean programming and design patterns.

Generate code, corrections, and refactorings that comply with the basic principles and nomenclature.

## TypeScript General Guidelines

### Basic Principles

- Use English for all code and documentation.
- Always declare the type of each variable and function (parameters and return value).
- Avoid using any.
- Create necessary types.
- Use JSDoc to document public classes and methods.
- Don't leave blank lines within a function.
- One export per file.

### Nomenclature

- Use PascalCase for classes.
- Use camelCase for variables, functions, and methods.
- Use kebab-case for file and directory names.
- Use UPPERCASE for environment variables.
- Avoid magic numbers and define constants.
- Start each function with a verb.
- Use verbs for boolean variables. Example: isLoading, hasError, canDelete, etc.
- Use complete words instead of abbreviations and correct spelling.
- Except for standard abbreviations like API, URL, etc.
- Except for well-known abbreviations:
  - i, j for loops
  - err for errors
  - ctx for contexts
  - req, res, next for middleware function parameters

### Functions

- In this context, what is understood as a function will also apply to a method.
- Write short functions with a single purpose. Less than 20 instructions.
- Name functions with a verb and something else.
- If it returns a boolean, use isX or hasX, canX, etc.
- If it doesn't return anything, use executeX or saveX, etc.
- Avoid nesting blocks by:
- Early checks and returns.
- Extraction to utility functions.
- Use higher-order functions (map, filter, reduce, etc.) to avoid function nesting.
- Use arrow functions for simple functions (less than 3 instructions).
- Use named functions for non-simple functions.
- Use default parameter values instead of checking for null or undefined.
- Reduce function parameters using RO-RO
- Use an object to pass multiple parameters.
- Use an object to return results.
- Declare necessary types for input arguments and output.
- Use a single level of abstraction.

### Data

- Don't abuse primitive types and encapsulate data in composite types.
- Avoid data validations in functions and use classes with internal validation.
- Prefer immutability for data.
- Use readonly for data that doesn't change.
- Use as const for literals that don't change.

### Classes

- Follow SOLID principles.
- Prefer composition over inheritance.
- Declare interfaces to define contracts.
- Write small classes with a single purpose.
- Less than 200 instructions.
- Less than 10 public methods.
- Less than 10 properties.

### Exceptions

- Use exceptions to handle errors you don't expect.
- If you catch an exception, it should be to:
- Fix an expected problem.
- Add context.
- Otherwise, use a global handler.

### Testing

- Follow the Arrange-Act-Assert convention for tests.
- Name test variables clearly.
- Follow the convention: inputX, mockX, actualX, expectedX, etc.
- Write unit tests for each public function.
- Use test doubles to simulate dependencies.
- Except for third-party dependencies that are not expensive to execute.
- Write acceptance tests for each module.
- Follow the Given-When-Then convention.

## Specific to NestJS

### Basic Principles

- Use modular architecture
- Encapsulate the API in modules.
- One module per main domain/route.
- One controller for its route.
  - And other controllers for secondary routes.
- A models folder with data types.
  - DTOs validated with class-validator for inputs.
  - Declare simple types for outputs.
- A services module with business logic and persistence.
  - Entities with MikroORM for data persistence.
  - One service per entity.
- A core module for nest artifacts
- Global filters for exception handling.
- Global middlewares for request management.
- Guards for permission management.
- Interceptors for request management.
- A shared module for services shared between modules.
- Utilities
- Shared business logic

### Testing

- Use the standard Jest framework for testing.
- Write tests for each controller and service.
- Write end to end tests for each api module.
- Add a admin/test method to each controller as a smoke test.

WebAssembly Z80 Cellular Automata .cursorrules prompt file

We're implementing a higher-level control structure for our z80 cellular automata simulation, which we call the "environmental region grid."
This system allows users to define and manipulate larger areas of influence over the underlying "primordial soup" of cells.

Key Concepts:
1. Soup Cells: The individual units of our cellular automata, which follow basic rules and interact with their neighbors.
2. Regions: Larger areas that encompass multiple soup cells. Each region can have unique properties that influence the behavior of the soup cells within it.
3. Environmental Region Grid: A grid overlaid on top of the soup cell grid, dividing the simulation space into discrete regions. This grid can be 4x4, 8x8, or 16x16, allowing for different levels of granularity.
4. Region Parameters: Each region has a set of adjustable parameters that affect the soup cells within it. These could include:
- Obstacle (A region that blocks the movement of soup cells)
- Directional influence (biasing cell interactions in specific directions)
- Randomness factor (introducing more or less chaos in cell behavior)
- Temperature (affecting overall activity levels)
- Energy levels (influencing the likelihood of certain cell states or interactions)
- Other custom parameters as needed
5. Dynamic Influence: The region parameters dynamically modify the behavior of soup cells, creating areas of distinct characteristics within the larger simulation.
6. User Interaction: Users can interact with the simulation by adjusting region parameters in real-time, allowing for on-the-fly modification of the simulation's behavior.
7. Visualization: The region grid and its effects are visually represented, allowing users to see the influence of their changes on the simulation.

Purpose:
This system adds a new layer of complexity and control to the cellular automata simulation. It allows for the creation of diverse environments within a single simulation, enabling users to explore how different regional properties affect the emergent behavior of the cellular automata.
By implementing this region grid system, we're providing a powerful tool for users to experiment with large-scale influences on cellular automata behavior, potentially leading to new insights and interesting emergent phenomena.

Plan:
1. Define the Region Structure:
Create a comprehensive data structure to represent each region. This structure should be flexible enough to accommodate various parameters that can influence the behavior of soup cells within that region. Consider including:
- Obstacle
- Directional influence (for each cardinal direction)
- Randomness factor
- Temperature
- Energy level
- Any other relevant parameters
Ensure that each parameter is represented by an appropriate data type, typically using floating-point numbers for continuous values or integers for discrete states. This structure will be the foundation of your region system, so design it with extensibility in mind.
2. Create the Region Grid:
Implement a two-dimensional array to represent the region grid. This grid should be flexible in size, allowing for configurations such as 4x4, 8x8, or 16x16. Each element of this array will be an instance of the region structure defined in step 1. Initialize this grid with default values for all parameters, ensuring a consistent starting state. Consider implementing methods to easily resize the grid and maintain the aspect ratio with the underlying soup cells.
3. Implement Soup Cell to Region Mapping:
Develop a system to efficiently map each soup cell to its corresponding region. This mapping is crucial for quick lookups during simulation. Create a separate array where each element represents a soup cell and contains the index or reference to its associated region. Implement functions to update this mapping whenever the region grid size changes. Ensure that this mapping system is optimized for performance, as it will be frequently accessed during the simulation.
4. Modify the Main Simulation Loop:
Update the core simulation logic to incorporate region parameters. For each soup cell update:
a. Determine the cell's corresponding region using the mapping created in step 3.
b. Retrieve the region's parameters.
c. Apply the effects of each parameter to the soup cell's behavior.
This might involve adjusting probabilities, modifying state transition rules, or influencing the cell's interaction with neighbors. Ensure that this integration is done efficiently to maintain simulation performance.
5. Implement Parameter-Specific Logic:
For each parameter in the region structure, create dedicated functions or methods to apply its effects. For example:
- Obstacle: Turns the cell into an obstacle, preventing it from being randomly selected, and preventing neighbor soup cells from interacting with it.
- Directional influence: Adjust the probability of a cell interacting with neighbors in specific directions.
- Randomness: Introduce variability in state transitions or cell behavior.
- Temperature: Affect the overall activity level or energy of cells within the region.
- Energy level: Influence the likelihood of certain operations or state changes.
Design these functions to be modular and easily expandable, allowing for the addition of new parameters in the future without major code restructuring.
6. Enhance the WASM Interface:
Extend the WebAssembly interface to handle the new region grid system. This involves:
a. Creating functions to set and get the entire region grid state, allowing for efficient data transfer between JavaScript and WASM.
b. Implementing additional functions for manipulating individual regions or specific parameters.
c. Ensuring these functions are properly exported and accessible from the JavaScript side.
d. Optimizing data transfer to minimize performance overhead, especially for larger grid sizes.
7. Develop the User Interface:
Design and implement a comprehensive user interface for manipulating the region grid. This should include:
a. A visual representation of the region grid, possibly overlaid on the main simulation view.
b. Interactive elements for each region, allowing users to adjust parameters individually.
c. Global controls for setting grid size and applying presets.
d. A system for selecting different "brushes" or tools for painting parameter values across multiple regions.
e. Real-time feedback showing the effects of parameter changes on the simulation.
Ensure that the UI is intuitive and responsive, providing users with immediate visual feedback on their actions.
8. Create a Region Visualization System:
Develop a robust visualization system for the regions. This should:
a. Visually represent the various parameters of each region, possibly using color coding, patterns, or overlays.
b. Update in real-time as parameters are changed, providing immediate feedback to the user.
c. Implement different visualization modes to focus on specific parameters or overall region states.
d. Ensure that the visualization is clear and distinguishable from the underlying soup cell simulation.
9. Implement Data Synchronization:
Create an efficient system for keeping the region grid data synchronized between the JavaScript UI and the WASM simulation. This might involve:
a. Implementing periodic updates at set intervals.
b. Creating an event-driven synchronization system that updates when changes occur.
c. Optimizing large data transfers to maintain smooth performance, possibly using typed arrays or other efficient data structures.
d. Implementing a queuing system for updates to prevent overwhelming the simulation with rapid changes.
10. Update the Shader Code:
Modify the fragment shader used for rendering the simulation to incorporate region effects. This involves:
a. Passing region data to the shader, either as a texture or uniform array.
b. Updating the shader logic to consider region parameters when rendering cells.
c. Implementing visual effects that reflect the influence of region parameters, such as color shifts, intensity variations, or particle effects.
d. Optimizing the shader code to maintain performance, especially for larger simulations or complex region effects.
This system will allow for complex, user-defined behaviors across the simulation space, significantly enhancing the depth and interactivity of the cellular automata simulation.

- Fully implement all requested functionality.
- Leave NO todo’s, placeholders or missing pieces.
- Be concise. Minimize any other prose.
- If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.

You have studied the instructions below extensively for how to write Rell code.
If you do not know how to do something in Rell, then ask instead of guessing.

# Core Concepts

## Modules
Rell code is organized into modules. A module is a collection of related declarations such as entities, operations, and functions.
Example of a simple module:

```
module;

entity user {
key username: text;
name: text;
age: integer;
}

function get_user(username: text) {
return user @? { .username == username };
}

query get_all_users() {
return user @* {};
}
```

## Entities
Entities are the primary way to define data structures in Rell. They correspond to database tables.

```
entity product {
key id: integer;
name: text;
price: decimal;
category: text;
}
```

## Operations
Operations are used to modify the blockchain state. They're similar to functions but are specifically for state-changing actions.

```
operation create_user(username: text, name: text, age: integer) {
create user(username, name, age);
}
```

## Queries
Queries are used to retrieve data from the blockchain without modifying the state.

```
query get_user_by_age(min_age: integer, max_age: integer) {
return user @* { .age >= min_age and .age <= max_age };
}
```

# Language Features

## Types
Rell supports various types:
- Simple Types:
- integer: Whole numbers
- decimal: Decimal numbers
- boolean: True or false
- text: Text strings
- byte_array: Array of bytes

Examples:
```
val age: integer = 25;
val price: decimal = 19.99;
val is_active: boolean = true;
val name: text = "Alice";
val data: byte_array = x"0A0B0C";
```

Complex Types:
- list: Ordered collection of elements
- set: Unordered collection of unique elements
- map<K, V>: Key-value pairs

```
val numbers: list = [1, 2, 3, 4, 5];
val unique_names: set = {"Alice", "Bob", "Charlie"};
val ages: map<text, integer> = {"Alice": 30, "Bob": 25, "Charlie": 35};
```

## Functions
Functions in Rell are defined using the function keyword.

Example:
```
function calculate_total(prices: list): decimal {
return prices @ {} ( @sum($) );
}
```

## Control Structures

If Statement:
```
if (condition) {
// Code block
} else if (not another_condition) {
// Code block
} else {
// Code block
}
```

When Statement (Similar to switch in other languages):
```
when (value) {
case1 -> // Code for case1
case2 -> // Code for case2
else -> // Default case
}

val result: text = when (age) {
case 18 -> "Adult"
case 13 -> "Teenager"
else -> "Child"
}
```

Loop Statements:

For loop:
```
for (item in collection) {
// Code block
}
```

While loop:
```
while (condition) {
// Code block
}
```

## Database Operations

### Create:
To create a new entity instance:
```
create user(username = "alice", name = "Alice Smith", age = 30);
```

### Update:
To update an existing entity instance:

```
update entity @? { .key == value } (
field1 = new_value1,
field2 = new_value2
);
```

### Delete:
To delete an existing entity instance:
```
delete entity @? { .key == value };
```

## System Libraries
Rell provides several system libraries for common operations:

###chain_context:
Provides information about the current blockchain state.
```
val current_block = chain_context.block_height;
```

### op_context:
Provides information about the current operation context.

```
val signer = op_context.signer;
```

### crypto:
Provides cryptographic functions.
Example:

```
val hash = crypto.sha256("Hello, World!");
```

### require Function:
Used for asserting conditions. If the condition is false, it throws an error.

```
function transfer(from: text, to: text, amount: decimal) {
require(amount > 0, "Amount must be positive");
// Transfer logic
}
```

## Namespaces
Namespaces are used to organize code and avoid naming conflicts.

```
namespace utils {
function helper1() { /* ... */ }
function helper2() { /* ... */ }
}

// Usage
utils.helper1();
```

## Importing Modules
Importing allows you to include entities from other modules in your current module.

```
import my_module;

query get_data() {
return my_module.some_entity @* {};
}
```
