# DSL Transpiler Architecture
|
||||
|
||||
This document provides a detailed overview of the Berry Animation DSL transpiler architecture, including the core processing flow and expression processing chain.
|
||||
|
||||
## Overview
|
||||
|
||||
The DSL transpiler (`transpiler.be`) converts Animation DSL code into executable Berry code. It uses a **ultra-simplified single-pass architecture** with comprehensive validation and code generation capabilities. The refactored transpiler emphasizes simplicity, robustness, and maintainability while providing extensive compile-time validation.
|
||||
|
||||
### Single-Pass Architecture Clarification
|
||||
|
||||
The transpiler is truly **single-pass** - it processes the token stream once from start to finish. When the documentation mentions "sequential steps" (like in template processing), these refer to **sequential operations within the single pass**, not separate passes over the data. For example:
|
||||
|
||||
- Template processing collects parameters, then collects body tokens **sequentially** in one pass
|
||||
- Expression transformation handles mathematical functions, then user variables **sequentially** in one operation
|
||||
- The transpiler never backtracks or re-processes the same tokens multiple times
|
||||
|
||||
## Core Processing Flow
|
||||
|
||||
The transpiler follows an **ultra-simplified single-pass architecture** with the following main flow:
|
||||

||||

### Statement Processing Details
|
||||
|
||||
#### Color Processing
|
||||
```
|
||||
process_color()
|
||||
├── expect_identifier() → color name
|
||||
├── validate_user_name() → check against reserved names
|
||||
├── expect_assign() → '='
|
||||
├── Check if function call (color provider)
|
||||
│ ├── Check template_definitions first
|
||||
│ ├── _validate_color_provider_factory_exists()
|
||||
│ ├── add("var name_ = animation.func(engine)")
|
||||
│ ├── Track in symbol_table for validation
|
||||
│ └── _process_named_arguments_for_color_provider()
|
||||
└── OR process_value() → static color value with symbol tracking
|
||||
```
|
||||
|
||||
#### Animation Processing
|
||||
```
|
||||
process_animation()
|
||||
├── expect_identifier() → animation name
|
||||
├── validate_user_name() → check against reserved names
|
||||
├── expect_assign() → '='
|
||||
├── Check if function call (animation factory)
|

||||
│ ├── _validate_animation_factory_creates_animation()

||||
│ ├── add("var name_ = animation.func(engine)")
|
||||
│ ├── Track in symbol_table for validation
|
||||
│ └── _process_named_arguments_for_animation()
|
||||
└── OR process_value() → reference or literal with symbol tracking
|
||||
```
|
||||
|
||||
#### Sequence Processing (Enhanced)
|
||||
```
|
||||
process_sequence()
|
||||
├── expect_identifier() → sequence name
|
||||
├── validate_user_name() → check against reserved names
|
||||
├── Track in sequence_names and symbol_table
|
||||
├── Parse multiple repeat syntaxes:
|
||||
│ ├── "sequence name repeat N times { ... }"
|
||||
│ ├── "sequence name forever { ... }"
|
||||
│ ├── "sequence name N times { ... }"
|
||||
│ └── "sequence name { repeat ... }"
|
||||
├── expect_left_brace() → '{'
|
||||
├── add("var name_ = animation.SequenceManager(engine, repeat_count)")
|
||||
├── while !check_right_brace()
|
||||
│ └── process_sequence_statement() (fluent interface)
|
||||
└── expect_right_brace() → '}'
|
||||
```
|
||||
|
||||
#### Template Processing (New)
|
||||
```
|
||||
process_template()
|
||||
├── expect_identifier() → template name
|
||||
├── validate_user_name() → check against reserved names
|
||||
├── expect_left_brace() → '{'
|
||||
├── Sequential step 1: collect parameters with type annotations
|
||||
├── Sequential step 2: collect body tokens

|
||||
│ └── Register as user function
|
||||
└── Track in symbol_table as "template"
|
||||
```
|
||||
|
||||
## Expression Processing Chain
|
||||
|
||||
The transpiler uses a **unified recursive descent parser** for expressions with **raw mode support** for closure contexts:
|
||||
|
||||
```
|
||||
process_value(context)
|
||||
└── process_additive_expression(context, is_top_level=true, raw_mode=false)
|
||||
├── process_multiplicative_expression(context, is_top_level, raw_mode)
|
||||
│ ├── process_unary_expression(context, is_top_level, raw_mode)
|
||||
│ │ └── process_primary_expression(context, is_top_level, raw_mode)
|
||||
│ │ ├── Parenthesized expression → recursive call
|
||||
│ │ ├── Function call handling:
|
||||
│ │ │ ├── Raw mode: mathematical functions → self.method()
|
||||
│ │ │ ├── Raw mode: template calls → template_func(self.engine, ...)
|
||||
│ │ │ ├── Regular mode: process_function_call() or process_nested_function_call()
|
||||
│ │ │ └── Simple function detection → _is_simple_function_call()
|
||||
│ │ ├── Color literal → convert_color() (enhanced ARGB support)
|
||||
│ │ ├── Time literal → process_time_value() (with variable support)
|
||||
│ │ ├── Percentage → process_percentage_value()
|
||||
│ │ ├── Number literal → return as-is
|
||||
│ │ ├── String literal → quote and return

```
|
||||
|
||||
### Expression Context Handling
|
||||
|
||||
The expression processor handles different contexts with **enhanced validation and processing**:
|
||||
|
||||
- **`"color"`** - Color definitions and assignments
|
||||
- **`"animation"`** - Animation definitions and assignments
|
||||
- **`"argument"`** - Function call arguments
|
||||
- **`"property"`** - Property assignments with validation
|
||||
- **`"variable"`** - Variable assignments with type tracking
|
||||
- **`"repeat_count"`** - Sequence repeat counts (special closure handling)
|
||||
- **`"time"`** - Time value processing with variable support
|
||||
- **`"array_element"`** - Array literal elements
|
||||
- **`"event_param"`** - Event handler parameters
|
||||
- **`"expression"`** - Raw expression context (for closures)
|
||||
|
||||
### Computed Expression Detection (Enhanced)
|
||||
|
||||
The transpiler automatically detects computed expressions that need closures with **improved accuracy**:
|
||||
|
||||
```
|
||||
is_computed_expression_string(expr_str)
|
||||
├── Check for arithmetic operators (+, -, *, /) with spaces
|
||||
├── Check for function calls (excluding simple functions)
|
||||
│ ├── Extract function name before parenthesis
|
||||
│ ├── Use _is_simple_function_call() to filter
|
||||
│ └── Only mark complex functions as needing closures
|
||||
├── Exclude simple parenthesized literals like (-1)
|
||||
└── Return true only for actual computations
|
||||
|
||||
create_computation_closure_from_string(expr_str)
|
||||
├── transform_expression_for_closure()
|
||||
│ ├── Sequential step 1: Transform mathematical functions → self.method()
|
||||
│ │ ├── Use dynamic introspection with is_math_method()
|
||||
│ │ ├── Check for existing "self." prefix
|
||||
│ │ └── Only transform if not already prefixed
|
||||
│ ├── Sequential step 2: Transform user variables → self.resolve(var_)
|
||||
│ │ ├── Find variables ending with _
|
||||
│ │ ├── Check for existing resolve() calls
|
||||
│ │ ├── Avoid double-wrapping
|
||||
│ │ └── Handle identifier character boundaries
|
||||
│ └── Clean up extra spaces
|
||||
└── Return "animation.create_closure_value(engine, closure)"
|
||||
|
||||
is_anonymous_function(expr_str)
|
||||
├── Check if expression starts with "(def "
|
||||
├── Check if expression ends with ")(engine)"
|
||||
└── Skip closure wrapping for already-wrapped functions
|
||||
```
|
||||
|
||||
## Validation System (Comprehensive)
|
||||
|
||||
The transpiler includes **extensive compile-time validation** with robust error handling:
|
||||
|
||||
### Factory Function Validation (Enhanced)
|
||||
```
|
||||
_validate_factory_function(func_name, expected_base_class)
|
||||
├── Check if function exists in animation module using introspection
|
||||
├── Check if it's callable (function or class)
|
||||
├── Create mock instance with MockEngine for type checking
|
||||
├── Validate instance type matches expected base class
|
||||
├── Handle mathematical functions separately (skip validation)
|
||||
└── Graceful error handling with try/catch
|
||||
|
||||
MockEngine class provides:
|
||||
├── time_ms property for validation
|
||||
├── get_strip_length() method returning default 30
|
||||
└── Minimal interface for instance creation
|
||||
```
|
||||
|
||||
### Parameter Validation (Real-time)
|
||||
```
|
||||
_validate_single_parameter(func_name, param_name, animation_instance)
|
||||
├── Use introspection to check if parameter exists
|
||||
├── Call instance._has_param(param_name) for validation
|
||||
├── Report detailed error messages with line numbers
|
||||
├── Validate immediately as parameters are parsed
|
||||
└── Graceful error handling to ensure transpiler robustness
|
||||
|
||||
_create_instance_for_validation(func_name)
|
||||
├── Create MockEngine for validation
|
||||
├── Call factory function with mock engine
|
||||
├── Return instance for parameter validation
|
||||
└── Handle creation failures gracefully
|
||||
```
|
||||
|
||||
### Reference Validation (Consolidated)
|
||||
```
|
||||
resolve_symbol_reference(name) - Unified symbol resolution
|
||||
├── Check if it's a named color → get_named_color_value()
|
||||
├── Check symbol_table for user-defined objects → name_
|
||||
├── Check sequence_names for sequences → name_
|
||||
├── Check animation module using introspection → animation.name
|
||||
└── Default to user-defined format → name_
|
||||
|
||||
validate_symbol_reference(name, context) - With error reporting
|
||||
├── Use symbol_exists() to check all sources
|
||||
├── Report detailed error with context information
|
||||
└── Return validation status
|
||||
|
||||
symbol_exists(name) - Existence check
|
||||
├── Check animation_dsl.is_color_name(name)
|
||||
├── Check symbol_table.contains(name)
|
||||
├── Check sequence_names.contains(name)
|
||||
├── Check introspect.contains(animation, name)
|
||||
└── Return boolean result
|
||||
```
|
||||
|
||||
### User Name Validation (Reserved Names)
|
||||
```
|
||||
validate_user_name(name, definition_type)
|
||||
├── Check against predefined color names
|
||||
├── Check against DSL statement keywords
|
||||
├── Report conflicts with suggestions for alternatives
|
||||
└── Prevent redefinition of reserved identifiers
|
||||
```
|
||||
|
||||
### Value Provider Validation (New)
|
||||
```
|
||||
_validate_value_provider_reference(object_name, context)
|
||||
├── Check if symbol exists using validate_symbol_reference()
|
||||
├── Check symbol_table markers for type information
|
||||
├── Validate instance types using isinstance()
|
||||
├── Ensure only value providers/animations can be reset/restarted
|
||||
└── Provide detailed error messages for invalid types
|
||||
```
|
||||
|
||||
## Code Generation Patterns
|
||||
|
||||
### Engine-First Pattern (Consistent)
|
||||
All factory functions use the engine-first pattern with **automatic strip initialization**:
|
||||
```berry
|
||||
# DSL: animation pulse = pulsating_animation(color=red, period=2s)
|
||||
# Generated:
|
||||
# Auto-generated strip initialization (using Tasmota configuration)
|
||||
var engine = animation.init_strip()
|
||||
|
||||
var pulse_ = animation.pulsating_animation(engine)
|
||||
pulse_.color = animation.red
|
||||
pulse_.period = 2000
|
||||
```
|
||||
|
||||
### Symbol Resolution (Consolidated)
|
||||
The transpiler resolves symbols at compile time using **unified resolution logic**:
|
||||
```berry
|
||||
# Built-in symbols from animation module → animation.symbol
|
||||
animation.red, animation.PALETTE_RAINBOW, animation.SINE, animation.COSINE
|
||||
|
||||
# User-defined symbols → symbol_
|
||||
my_color_, my_animation_, my_sequence_
|
||||
|
||||
# Named colors → direct ARGB values (resolved at compile time)
|
||||
red → 0xFFFF0000, blue → 0xFF0000FF
|
||||
|
||||
# Template calls → template_function(engine, args)
|
||||
my_template(red, 2s) → my_template_template(engine, 0xFFFF0000, 2000)
|
||||
```
|
||||
|
||||
### Closure Generation (Enhanced)
|
||||
Dynamic expressions are wrapped in closures with **mathematical function support**:
|
||||
```berry
|
||||
# DSL: animation.opacity = strip_length() / 2 + 50
|
||||
# Generated:
|
||||
animation.opacity = animation.create_closure_value(engine,
|
||||
def (self) return self.resolve(strip_length_(engine)) / 2 + 50 end)
|
||||
|
||||
# DSL: animation.opacity = max(100, min(255, user.rand_demo() + 50))
|
||||
# Generated:
|
||||
animation.opacity = animation.create_closure_value(engine,
|
||||
def (self) return self.max(100, self.min(255, animation.get_user_function('rand_demo')(self.engine) + 50)) end)
|
||||
|
||||
# Mathematical functions are automatically detected and prefixed with self.
|
||||
# User functions are wrapped with animation.get_user_function() calls
|
||||
```
|
||||
|
||||
### Template Generation (New)
|
||||
Templates are transpiled into Berry functions and registered as user functions:
|
||||
```berry
|
||||
# DSL Template:
|
||||
template pulse_effect {
|
||||
param color type color
|
||||
param speed
|
||||
|
||||
animation pulse = pulsating_animation(color=color, period=speed)
|
||||
run pulse
|
||||
}
|
||||
|
||||
# Generated:
|
||||
def pulse_effect_template(engine, color_, speed_)
|
||||
var pulse_ = animation.pulsating_animation(engine)
|
||||
pulse_.color = color_
|
||||
pulse_.period = speed_
|
||||
engine.add(pulse_)
|
||||
end
|
||||
|
||||
animation.register_user_function('pulse_effect', pulse_effect_template)
|
||||
```
|
||||
|
||||
### Sequence Generation (Fluent Interface)
|
||||
Sequences use fluent interface pattern for better readability:
|
||||
```berry
|
||||
# DSL: sequence demo { play anim for 2s; wait 1s }
|
||||
# Generated:
|
||||
var demo_ = animation.SequenceManager(engine)
|
||||
.push_play_step(anim_, 2000)
|
||||
.push_wait_step(1000)
|
||||
|
||||
# Nested repeats use sub-sequences:
|
||||
var demo_ = animation.SequenceManager(engine)
|
||||
.push_repeat_subsequence(animation.SequenceManager(engine, 3)
|
||||
.push_play_step(anim_, 1000)
|
||||
)
|
||||
```
|
||||
|
||||
## Template System (Enhanced)
|
||||
|
||||
Templates are transpiled into Berry functions with **comprehensive parameter handling**:
|
||||
|
||||
```
|
||||
process_template()
|
||||
├── expect_identifier() → template name
|
||||
├── validate_user_name() → check against reserved names
|
||||
├── expect_left_brace() → '{'
|
||||
├── Sequential step 1: collect parameters with type annotations
|
||||
│ ├── Parse "param name type annotation" syntax
|
||||
│ ├── Store parameter names and optional types
|
||||
│ └── Support both typed and untyped parameters
|
||||
├── Sequential step 2: collect body tokens until closing brace
|
||||
│ ├── Handle nested braces correctly
|
||||
│ ├── Preserve all tokens for later transpilation
|
||||
│ └── Track brace depth for proper parsing
|
||||
├── expect_right_brace() → '}'
|
||||
├── Store in template_definitions for call resolution
|
||||
├── generate_template_function()
|
||||
│ ├── Create new SimpleDSLTranspiler instance for body
|
||||
│ ├── Set up fresh symbol table with parameters
|
||||
│ ├── Mark strip as initialized (templates assume engine exists)
|
||||
│ ├── Transpile body using transpile_template_body()
|
||||
│ ├── Generate Berry function with engine + parameters
|
||||
│ ├── Handle transpilation errors gracefully
|
||||
│ └── Register as user function automatically
|
||||
└── Track in symbol_table as "template"
|
||||
```
|
||||
|
||||
### Template Call Resolution (Multiple Contexts)
|
||||
```berry
|
||||
# DSL template call in animation context:
|
||||
animation my_anim = my_template(red, 2s)
|
||||
# Generated: var my_anim_ = my_template_template(engine, 0xFFFF0000, 2000)
|
||||
|
||||
# DSL template call in property context:
|
||||
animation.opacity = my_template(blue, 1s)
|
||||
# Generated: animation.opacity = my_template_template(self.engine, 0xFF0000FF, 1000)
|
||||
|
||||
# DSL standalone template call:
|
||||
my_template(green, 3s)
|
||||
# Generated: my_template_template(engine, 0xFF008000, 3000)
|
||||
```
|
||||
|
||||
### Template Body Transpilation
|
||||
Templates use a **separate transpiler instance** with isolated symbol table:
|
||||
- Fresh symbol table prevents name conflicts
|
||||
- Parameters are added as "parameter" markers
|
||||
- Run statements are processed immediately (not collected)
|
||||
- Template calls can be nested (templates calling other templates)
|
||||
- Error handling preserves context information
|
||||
|
||||
## Error Handling (Robust)
|
||||
|
||||
The transpiler provides **comprehensive error reporting** with graceful degradation:
|
||||
|
||||
### Error Categories
|
||||
- **Syntax errors** - Invalid DSL syntax with line numbers
|
||||
- **Factory validation** - Non-existent animation/color factories with suggestions
|
||||
- **Parameter validation** - Invalid parameter names with class context
|
||||
- **Reference validation** - Undefined object references with context information
|
||||
- **Constraint validation** - Parameter values outside valid ranges
|
||||
- **Type validation** - Incorrect parameter types with expected types
|
||||
- **Template errors** - Template definition and call validation
|
||||
- **Reserved name conflicts** - User names conflicting with built-ins
|
||||
|
||||
### Error Reporting Features
|
||||
```berry
|
||||
error(msg)
|
||||
├── Capture current line number from token
|
||||
├── Format error with context: "Line X: message"
|
||||
├── Store in errors array for batch reporting
|
||||
└── Continue transpilation for additional error discovery
|
||||
|
||||
get_error_report()
|
||||
├── Check if errors exist
|
||||
├── Format comprehensive error report
|
||||
├── Include all errors with line numbers
|
||||
└── Provide user-friendly error messages
|
||||
```
|
||||
|
||||
### Graceful Error Handling
|
||||
- **Try-catch blocks** around validation to prevent crashes
|
||||
- **Robust validation** that continues on individual failures
|
||||
- **Skip statement** functionality to recover from parse errors
|
||||
- **Default values** when validation fails to maintain transpilation flow
|
||||
- **Context preservation** in error messages for better debugging
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Ultra-Simplified Architecture
|
||||
- **Single-pass processing** - tokens processed once from start to finish
|
||||
- **Incremental symbol table** - builds validation context as it parses
|
||||
- **Immediate validation** - catches errors as soon as they're encountered
|
||||
- **Minimal state tracking** - only essential information is maintained
|
||||
|
||||
### Compile-Time Optimization
|
||||
- **Symbol resolution at transpile time** - eliminates runtime lookups
|
||||
- **Parameter validation during parsing** - catches errors early
|
||||
- **Template pre-compilation** - templates become efficient Berry functions
|
||||
- **Closure detection** - only wraps expressions that actually need it
|
||||
- **Mathematical function detection** - uses dynamic introspection for accuracy
|
||||
|
||||
### Memory Efficiency
|
||||
- **Streaming token processing** - no large intermediate AST structures
|
||||
- **Direct code generation** - output generated as parsing proceeds
|
||||
- **Minimal intermediate representations** - tokens and symbol table only
|
||||
- **Template isolation** - separate transpiler instances prevent memory leaks
|
||||
- **Graceful error handling** - prevents memory issues from validation failures
|
||||
|
||||
### Validation Efficiency
|
||||
- **MockEngine pattern** - lightweight validation without full engine
|
||||
- **Introspection caching** - validation results can be cached
|
||||
- **Early termination** - stops processing invalid constructs quickly
|
||||
- **Batch error reporting** - collects multiple errors in single pass
|
||||
|
||||
## Integration Points
|
||||
|
||||
### Animation Module Integration
|
||||
- **Factory function discovery** via introspection with existence checking
|
||||
- **Parameter validation** using instance methods and _has_param()
|
||||
- **Symbol resolution** using module contents with fallback handling
|
||||
- **Mathematical function detection** using dynamic introspection of ClosureValueProvider
|
||||
- **Automatic strip initialization** when no explicit strip configuration
|
||||
|
||||
### User Function Integration
|
||||
- **Template registration** as user functions with automatic naming
|
||||
- **User function call detection** with user. prefix handling
|
||||
- **Closure generation** for computed parameters with mathematical functions
|
||||
- **Template call resolution** in multiple contexts (animation, property, standalone)
|
||||
- **Import statement processing** for user function modules
|
||||
|
||||
### DSL Language Integration
|
||||
- **Comment preservation** in generated Berry code
|
||||
- **Inline comment handling** with proper spacing
|
||||
- **Multiple syntax support** for sequences (repeat variants)
|
||||
- **Palette syntax flexibility** (tuple vs alternative syntax)
|
||||
- **Time unit conversion** with variable support
|
||||
- **Percentage conversion** to 0-255 range
|
||||
|
||||
### Robustness Features
|
||||
- **Graceful error recovery** - continues parsing after errors
|
||||
- **Validation isolation** - validation failures don't crash transpiler
|
||||
- **Symbol table tracking** - maintains context for validation
|
||||
- **Template isolation** - separate transpiler instances prevent conflicts
|
||||
- **Reserved name protection** - prevents conflicts with built-in identifiers
|
||||
|
||||
## Key Architectural Changes
|
||||
|
||||
The refactored transpiler emphasizes:
|
||||
|
||||
1. **Simplicity** - Ultra-simplified single-pass architecture
|
||||
2. **Robustness** - Comprehensive error handling and graceful degradation
|
||||
3. **Validation** - Extensive compile-time validation with detailed error messages
|
||||
4. **Flexibility** - Support for templates, multiple syntax variants, and user functions
|
||||
5. **Performance** - Efficient processing with minimal memory overhead
|
||||
6. **Maintainability** - Clear separation of concerns and unified processing methods
|
||||
|
||||
This architecture ensures robust, efficient transpilation from DSL to executable Berry code while providing comprehensive validation, detailed error reporting, and extensive language features.
