I provide a complete actor-like system - with explicit mailbox-as-actors separation, type-safe message passing, and - effectful actions through a user-friendly DSL. - - ## Quick Start - - **For the complete interactive tutorial with runnable examples**, see the - [**Livebook Tutorial**](README.livemd) which includes: - - Step-by-step guided examples - - Interactive code cells you can run - - Real-world usage patterns - - System management examples - - Advanced patterns and best practices - - ### Basic Usage - - The recommended approach is to use `use EngineSystem`: - - ```elixir - use EngineSystem - - # Start the system - {:ok, _} = start() - - # Define an engine using the DSL - defengine MyEngine do - version "1.0.0" - - interface do - message :ping - message :pong - end - - behaviour do - on_message :ping, _msg, _config, _env, sender do - {:ok, [{:send, sender, :pong}]} - end - end - end - - # Spawn and interact with engines - {:ok, address} = spawn_engine(MyEngine) - send_message(address, {:ping, %{}}) - ``` - - This single import gives you access to: - - **DSL macros** for defining engines (`defengine`, `version`, `config`, etc.) - - **Utility functions** for message processing and validation - - **API functions** for system management, engine lifecycle, and communication - - - - ## Key Features - - ### Engine Definition DSL - - User-friendly macro system for defining engines with compile-time validation: - - ```elixir - defengine KVStore do - version "1.0.0" - - config do - %{max_size: 1000, timeout: 30.0} - end - - interface do - message :put, key: :atom, value: :any - message :get, key: :atom - message :result, value: {:option, :any} - end - - behaviour do - on_message :put, %{key: key, value: value}, _config, env, sender do - new_env = %{env | store: Map.put(env.store, key, value)} - {:ok, [ - {:update_environment, new_env}, - {:send, sender, :ack} - ]} - end - end - end - ``` - - ### Mailbox-as-Actors Pattern - - First-class mailbox engines that handle message reception and validation: - - - Independent message filtering and queueing policies - - Backpressure management via demand-driven flow - - Contract checking against processing engine interfaces - - ### Type-Safe Messaging - - Interface validation and message contracts ensure system reliability: - - ```elixir - # Validate messages before sending - case validate_message(engine_address, {:get, %{key: :my_key}}) do - :ok -> send_message(engine_address, {:get, %{key: :my_key}}) - {:error, reason} -> handle_invalid_message(reason) - end - ``` - - ### Effect System - - Composable effects for state management and communication: - - ```elixir - {:ok, [ - {:update_environment, new_env}, - {:send, target_address, response}, - {:spawn, NewEngine, config, environment} - ]} - ``` - - ### System Management - - Comprehensive lifecycle and monitoring APIs: - - - System health monitoring - - ```elixir - system_info = get_system_info() - IO.puts("Running engines: \#{system_info.running_instances}") - - ``` - - - Cleanup and maintenance - - ```elixir - cleaned = clean_terminated_engines() - IO.puts("Cleaned up \#{cleaned} terminated engines") - ``` - - ## API Reference - - ### System Management - - `start/0` - Start the EngineSystem application - - `stop/0` - Stop the EngineSystem application gracefully - - `get_system_info/0` - Get comprehensive system health and metrics - - `clean_terminated_engines/0` - Clean up terminated engines from registry - - ### Engine Lifecycle - - `spawn_engine/1..6` - Spawn engine instances with flexible configuration - - `spawn_engine_with_mailbox/1` - Spawn with explicit mailbox configuration - - `terminate_engine/1` - Gracefully terminate engine instances - - ### Communication - - `send_message/2..3` - Send messages between engines with optional sender - - `validate_message/2` - Validate messages against engine interface contracts - - ### Registry and Discovery - - `register_spec/1` - Register engine specifications for spawning - - `lookup_spec/1..2` - Look up engine specifications by name/version - - `list_instances/0` - List all running engine instances with metadata - - `list_specs/0` - List all registered engine specifications - - `lookup_instance/1` - Get detailed instance information by address - - `lookup_address_by_name/1` - Look up addresses by registered names - - ### Interface Utilities - - `has_message?/3` - Check if an engine supports a specific message tag - - `get_message_fields/3` - Get field specifications for message tags - - `get_message_tags/2` - Get all supported message tags for an engine - - `get_instance_message_tags/1` - Get message tags for running instances - - ## DSL Macros - - When you `use EngineSystem`, you get access to all the DSL macros: - - `defengine/2` - Define a new engine with configuration options - - `version/1` - Set engine version for registry and compatibility - - `config/1` - Define engine configuration structure and defaults - - `env/1` - Define engine environment (state) structure and defaults - - `interface/1` - Define message interface with type specifications - - `behaviour/1` - Define engine behavior rules and message handlers - - ## Utility Functions - - Common utilities for engine development: - - `validate_message_for_pe/2` - Validate messages against processing engine specs - - `extract_messages/3` - Extract messages from queues with filtering support - - `apply_filter/2` - Apply message filters safely with error handling - - `extract_message_tag/1` - Extract message tags from various payload formats - - `validate_address/1` - Validate engine address format and structure - - `fresh_id/0` - Generate globally unique identifiers - - ## Examples and Patterns - - The library includes comprehensive examples in the **Examples** section: - - **Simple Echo Engine** - Basic message echoing - - **Stateless Calculator** - Functional computation engine - - **Stateful Counter** - State management patterns - - **Key-Value Store** - Advanced configuration and error handling - - **Ping/Pong System** - Inter-engine communication patterns - - ## Architecture Notes -

- ### `:subtract` - Subtraction Operation - **Request Format**: `{:subtract, %{a: float, b: float}}` - **Response Format**: `{:result, float}` or `{:error, :negative_not_allowed}` - **Purpose**: Subtract second number from first with negative handling - - ### `:multiply` - Multiplication Operation - **Request Format**: `{:multiply, %{a: float, b: float}}` - **Response Format**: `{:result, float}` or `{:error, :number_too_large}` - **Purpose**: Multiply two numbers with magnitude limit protection -

**Purpose**: Divide first number by second with zero-division protection - - ## Message Handling - - Here's exactly what happens when I receive each message type: - - ### When I Receive `:add` Messages - - 1. **Input Validation**: I extract float values `a` and `b` from the message payload - 2. **Arithmetic Operation**: I compute `result = a + b` using floating-point arithmetic - 3. **Overflow Check**: I verify `abs(result) <= max_number` to prevent overflow - 4. **Precision Rounding**: I round the result to `decimal_precision` decimal places - 5. **Response Generation**: I send `{:result, rounded_value}` or `{:error, :number_too_large}` - - ```elixir - # Input: {:add, %{a: 10.5, b: 5.3}} - # Process: 10.5 + 5.3 = 15.8, rounded to configured precision - # Output: {:result, 15.8} sent back to sender - ``` - - ### When I Receive `:subtract` Messages - - 1. **Input Validation**: I extract float values `a` and `b` from the payload - 2. **Arithmetic Operation**: I compute `result = a - b` - 3. **Negative Check**: I verify result is non-negative if `allow_negative` is false - 4. **Precision Rounding**: I round to configured decimal precision - 5. **Response Generation**: I send result or negative error based on configuration - - ```elixir - # Input: {:subtract, %{a: 10.0, b: 3.0}} - # Process: 10.0 - 3.0 = 7.0, check negative policy - # Output: {:result, 7.0} sent back to sender -

4. **Precision Control**: I apply decimal precision rounding - 5. **Error Handling**: I generate appropriate error for magnitude overflow - - ```elixir - # Input: {:multiply, %{a: 2.5, b: 4.0}} - # Process: 2.5 * 4.0 = 10.0, check magnitude limits - # Output: {:result, 10.0} sent back to sender - ``` - - ### When I Receive `:divide` Messages - - 1. **Input Validation**: I extract dividend `a` and divisor `b` - 2. **Zero Check**: I verify `abs(b) >= operator_precision` to prevent division by zero - 3. **Arithmetic Operation**: I compute `result = a / b` if divisor is valid - 4. **Magnitude Verification**: I check result magnitude against limits - 5. **Precision & Response**: I round and send result or appropriate error - - ```elixir - # Input: {:divide, %{a: 22.0, b: 7.0}} - # Process: 22.0 / 7.0 = 3.142857..., round to precision - # Output: {:result, 3.1428571429} sent back to sender - ``` - - ## Error Conditions - - I generate specific errors for different failure scenarios: - - ### `:number_too_large` - Returned when any operation result exceeds the configured `max_number` limit. - This protects against arithmetic overflow and maintains system stability. - - ### `:negative_not_allowed` - Returned when subtraction produces negative results but `allow_negative` is false. - This enforces domain-specific constraints on mathematical operations. - - ### `:division_by_zero` - Returned when division attempts involve divisors smaller than `operator_precision`. - This prevents mathematical undefined behavior and system crashes. - - ## Usage Examples - - ### Basic Arithmetic Operations - ```elixir - # Spawn me with default configuration - {:ok, calc_addr} = EngineSystem.API.spawn_engine(Examples.CalculatorEngine) - - # Perform addition - EngineSystem.API.send_message(calc_addr, {:add, %{a: 10.5, b: 5.3}}) - # I respond with: {:result, 15.8} - - # Perform division - EngineSystem.API.send_message(calc_addr, {:divide, %{a: 22.0, b: 7.0}}) - # I respond with: {:result, 3.1428571429} - ``` - - ### Custom Configuration - ```elixir - # Spawn me with custom limits - custom_config = %{ - max_number: 100, - decimal_precision: 2, - allow_negative: false - } - {:ok, limited_calc} = EngineSystem.API.spawn_engine(Examples.CalculatorEngine, custom_config) - - # Test overflow protection - EngineSystem.API.send_message(limited_calc, {:multiply, %{a: 50.0, b: 3.0}}) - # I respond with: {:error, :number_too_large} - ``` - - ### Error Handling Examples - ```elixir - # Test division by zero - EngineSystem.API.send_message(calc_addr, {:divide, %{a: 10.0, b: 0.0}}) - # I respond with: {:error, :division_by_zero} - - # Test negative restriction (if configured) - EngineSystem.API.send_message(limited_calc, {:subtract, %{a: 5.0, b: 10.0}}) - # I respond with: {:error, :negative_not_allowed} - ``` - - ## Integration Scenarios -

- `mode`: `:unlimited` or `:limited` operation mode - - `auto_reset`: Whether I automatically reset when reaching limits - - `notifications`: Whether I send detailed response notifications - - ### Environment State - I maintain rich internal state: - - `counter`: My current counter value - - `increment_by`: Step size for increment operations - - `max_count`: Maximum allowed counter value - - `enabled`: Whether I'm currently accepting operations - - `history`: List of previous counter values - - `metadata`: Additional state information - - ## Message Interface - - I handle five primary message types: - - ### `:increment` Messages - Increase my counter by the configured step value. I respect limits and - provide appropriate error responses when limits are exceeded. - - ### `:decrement` Messages - Decrease my counter by the configured step value with automatic floor - protection (never going below zero). - - ### `:reset` Messages - Reset my counter to zero and clear my history, providing a clean slate - for new operations. - - ### `:get_count` Messages - Return my current counter value without modifying state, useful for - monitoring and status checking. - - ### `:add` Messages - Add arbitrary integer values to my counter, providing flexibility - beyond the standard increment operation. - - ## Error Handling - - I provide comprehensive error handling for various edge cases: - - `:max_count_reached` when operations would exceed configured limits - - `:counter_disabled` when I'm temporarily disabled - - Graceful handling of invalid operations - - ## Usage Examples - - # Spawn me with default configuration - {:ok, counter_addr} = EngineSystem.spawn_engine(Examples.CounterEngine) - - # Basic operations - send_message(counter_addr, {:increment, %{}}) - send_message(counter_addr, {:get_count, %{}}) - send_message(counter_addr, {:add, %{value: 5}}) - send_message(counter_addr, {:reset, %{}}) - - # Custom configuration - custom_config = %{mode: :limited, notifications: false} - {:ok, limited_counter} = EngineSystem.spawn_engine(Examples.CounterEngine, custom_config) - - ## Design Patterns - - I demonstrate several important engine patterns: - - **Stateful Operations**: Maintaining persistent data across messages - - **Configuration Management**: Using simplified config syntax with type inference - - **Error Handling**: Providing meaningful error responses for edge cases - - **History Tracking**: Maintaining audit trails of state changes - - **Conditional Logic**: Respecting configuration settings and operational state - - **Response Consistency**: Uniform response patterns across all operations - - ## State Management Philosophy - - I embody best practices for engine state management: - - **Immutable Updates**: All state changes create new state objects - - **Atomic Operations**: Each message handler completes fully or not at all - - **State Validation**: I validate state consistency before and after operations - - **History Preservation**: I maintain operational history for debugging and auditing - - ## Educational Value - - I serve multiple educational purposes: - - **State Management**: Demonstrating how to handle complex engine state - - **Configuration Patterns**: Showing simplified config syntax usage - - **Error Handling**: Implementing comprehensive error response patterns - - **Message Design**: Providing examples of clean message interface design - - I serve as both a practical utility for applications requiring counter - functionality and an educational foundation for understanding stateful - engine design patterns within the EngineSystem. - """ + @moduledoc "I maintain a counter with increment, decrement, and history tracking capabilities." version("2.0.0") # This is a processing engine From 9881a53dc838a7450c7c18fc0f75e02385ae4bfa Mon Sep 17 00:00:00 2001 From: Jonathan Cubides Date: Tue, 9 Sep 2025 13:59:01 +0200 Subject: [PATCH 10/18] Simplifying drastically the documentation for better maintainability --- lib/engine_system/api.ex | 32 +- lib/engine_system/application.ex | 14 - lib/engine_system/engine.ex | 14 +- lib/engine_system/engine/behaviour.ex | 87 +---- lib/engine_system/engine/dsl.ex | 216 +--------- lib/engine_system/engine/effect.ex | 84 +--- lib/engine_system/engine/instance.ex | 14 +- lib/engine_system/engine/spec.ex | 22 +- lib/engine_system/engine/state.ex | 12 +- lib/engine_system/lifecycle.ex | 272 +------------ lib/engine_system/mailbox/behaviour.ex | 21 - lib/engine_system/supervisor.ex | 142 +------ lib/engine_system/system/message.ex | 45 --- lib/engine_system/system/registry.ex | 71 ---- lib/engine_system/system/services.ex | 369 +----------------- lib/engine_system/system/spawner.ex | 66 +--- lib/engine_system/system/spawner/logger.ex | 122 ------ lib/engine_system/system/spawner/validator.ex | 166 -------- lib/engine_system/system/utilities.ex | 114 ------ 19 files changed, 75 insertions(+), 1808 deletions(-) diff --git a/lib/engine_system/api.ex b/lib/engine_system/api.ex index 312b0c4..9bf4879 100644 --- a/lib/engine_system/api.ex +++ b/lib/engine_system/api.ex @@ -10,7 +10,7 @@ defmodule EngineSystem.API do alias EngineSystem.System.{Registry, Services, Spawner} @doc """ - I start the EngineSystem application with all necessary supervisors and services. + I start the EngineSystem application.

Added missing newlines for consistency in various modules. - Enhanced the organization of function definitions in the DSL, including the introduction of helper functions for better separation of concerns. - Updated references to use the alias for ConfigBuilder and EnvironmentBuilder for clarity. - Streamlined the diagram generation logic in the DiagramGenerator module. - Improved error handling and diagnostics in the DSL interface definitions. These changes contribute to a cleaner and more maintainable codebase. --- lib/engine_system/engine.ex | 2 + lib/engine_system/engine/diagram_generator.ex | 18 +-- lib/engine_system/engine/dsl.ex | 43 ++++- .../engine/dsl/config_builder.ex | 3 +- .../engine/dsl/environment_builder.ex | 3 +- .../engine/dsl/interface_builder.ex | 151 +----------------- 6 files changed, 55 insertions(+), 165 deletions(-) diff --git a/lib/engine_system/engine.ex b/lib/engine_system/engine.ex index 6f0591b..b71b132 100644 --- a/lib/engine_system/engine.ex +++ b/lib/engine_system/engine.ex @@ -105,6 +105,7 @@ defmodule EngineSystem.Engine do catch _ -> false end + {:arity, 3} -> try do filter.(message, nil, nil) @@ -113,6 +114,7 @@ defmodule EngineSystem.Engine do catch _ -> false end + _ -> # Default to 1-arity for backward compatibility try do diff --git a/lib/engine_system/engine/diagram_generator.ex b/lib/engine_system/engine/diagram_generator.ex index f9de3eb..a1e56aa 100644 --- a/lib/engine_system/engine/diagram_generator.ex +++ b/lib/engine_system/engine/diagram_generator.ex @@ -807,10 +807,11 @@ defmodule EngineSystem.Engine.DiagramGenerator do end defp generate_sequences_for_flow(flow) do - sequences = [] - |> add_initial_sequence(flow) - |> add_note_sequence(flow) - |> add_effect_sequences(flow) + sequences = + [] + |> add_initial_sequence(flow) + |> add_note_sequence(flow) + |> add_effect_sequences(flow) sequences end @@ -825,7 +826,8 @@ defmodule EngineSystem.Engine.DiagramGenerator do :effects_list when flow.source_engine == :client -> generate_client_to_engine_sequence(flow) - handler_type when handler_type in [:effect_tuple, :inferred_response] and flow.source_engine != :client -> + handler_type + when handler_type in [:effect_tuple, :inferred_response] and flow.source_engine != :client -> generate_engine_to_engine_sequence(flow) _ when flow.source_engine == :client -> @@ -866,6 +868,7 @@ defmodule EngineSystem.Engine.DiagramGenerator do defp generate_function_note(flow) do metadata = Map.get(flow, :metadata, %{}) + if function = Map.get(metadata, :function) do " Note over #{format_participant_name(flow.target_engine)}: Handled by #{function}/#{Map.get(metadata, :arity, "?")}" else @@ -1060,10 +1063,7 @@ defmodule EngineSystem.Engine.DiagramGenerator do # Get all registered engine specs from the system registry defp get_all_registered_specs do # Attempt to get registered specs from the registry - case EngineSystem.System.Registry.list_specs() do - specs when is_list(specs) -> specs - _ -> [] - end + EngineSystem.System.Registry.list_specs() rescue # Registry might not be available at compile time _ -> [] diff --git a/lib/engine_system/engine/dsl.ex b/lib/engine_system/engine/dsl.ex index 7a4d8aa..6c165cc 100644 --- a/lib/engine_system/engine/dsl.ex +++ b/lib/engine_system/engine/dsl.ex @@ -120,6 +120,7 @@ defmodule EngineSystem.Engine.DSL do description: "Invalid engine mode: #{inspect(spec_data.mode)}.
