The implementation will capture exactly what a template reads and uses during rendering, then write a single JSON file containing only scalars, arrays, and maps sufficient to re-run the template without Drop implementations or external file system access. + +## Project Structure + +``` +lib/liquid/ +├── template_recorder.rb # Main TemplateRecorder class and API +├── template_recorder/ +│ ├──

TemplateRecorder Main API (`lib/liquid/template_recorder.rb`) + +```ruby +module Liquid + class TemplateRecorder + # Primary recording API + def self.record(filename, &block) + def self.replay_from(filename, mode: :compute) + + # Internal factory methods + def self.create_recorder + def self.create_replayer(data, mode) + end +end +``` + +**Key Responsibilities:** +- Provide top-level recording and replay API +- Manage thread-local recorder instance during recording block +- Handle file I/O for JSON recording files +- Coordinate between recorder and replayer components + +**Implementation Details:** +- Use `Thread.current[:liquid_recorder]` for file system hooks +- Wrap template rendering with recorder injection via `context.registers[:recorder]` +- Ensure single JSON file output after block completion +- Handle multiple parse/render cycles within single recording block + +### 1.2 Core Recorder (`lib/liquid/template_recorder/recorder.rb`) + +```ruby +class Liquid::TemplateRecorder::Recorder + def initialize + @events = EventLog.new + @binding_tracker = BindingTracker.new + @file_reads = {} + @template_info = {} + end + + # Event recording methods + def emit_drop_read(drop_object, method_name, result) + def emit_filter_call(name, input, args, output, location = nil) + def emit_file_read(path, content) + def for_enter(collection_expr) + def for_item(index, item) + def for_exit + + # Finalization + def finalize_recording +end +``` + +**Key Responsibilities:** +- Collect all recording events during template execution +- Maintain object ID to variable path bindings +- Track loop nesting and item binding +- Generate minimal assigns tree from recorded events +- Serialize final JSON with stable ordering + +**Implementation Details:** +- Use `object_id` mapping to track Drop instances to variable paths +- Handle nested loops with stack-based item binding +- Only store scalars in final JSON; use objects transiently for path building +- Coalesce duplicate reads; last value wins for conflicts + +### 1.3 Binding Tracker (`lib/liquid/template_recorder/binding_tracker.rb`) + +```ruby +class Liquid::TemplateRecorder::BindingTracker + def initialize + @object_bindings = {} # object_id => variable_path + @loop_stack = [] # current loop context stack + end + + def bind_root_object(object, path) + def bind_loop_item(object, path) + def resolve_binding_path(object) + def enter_loop(collection_path) + def exit_loop +end +``` + +**Key Responsibilities:** +- Map object IDs to their canonical variable paths +- Handle nested loop item binding +- Resolve property access paths (e.g., `product.variants[1].name`) +- Maintain loop context stack for nested iterations + +## Phase 2: Integration Hooks + +### 2.1 Drop Recording Hook (`lib/liquid/drop.rb`) + +**Modification to `invoke_drop` method:** + +```ruby +def invoke_drop(method_or_key) + result = if self.class.invokable?(method_or_key) + send(method_or_key) + else + liquid_method_missing(method_or_key) + end + + # Recording hook - only active when recorder present + if @context && (recorder = @context.registers[:recorder]) + recorder.emit_drop_read(self, method_or_key, result) + end + + result +end +``` + +**Key Considerations:** +- Zero overhead when no recorder present (single hash lookup) +- Access to `@context` for recorder retrieval +- Called after result computation to capture actual values +- Handles both successful method calls and `liquid_method_missing` + +### 2.2 Filter Recording Hook (`lib/liquid/strainer_template.rb`) + +**Modification to `invoke` method:** + +```ruby +def invoke(method, *args) + result = if self.class.invokable?(method) + send(method, *args) + elsif @context.strict_filters + raise Liquid::UndefinedFilter, "undefined filter #{method}" + else + args.first + end + + # Recording hook + if (recorder = @context.registers[:recorder]) + recorder.emit_filter_call(method, args.first, args[1..-1], result) + end + + result +rescue ::ArgumentError => e + raise Liquid::ArgumentError, e.message, e.backtrace +end +``` + +**Key Considerations:** +- Record input, arguments, and output for each filter call +- Capture location information when available +- Handle filter errors appropriately +- Sequential filter log for strict replay mode + +### 2.3 For Loop Recording Hooks (`lib/liquid/tags/for.rb`) + +**Modifications to `render_segment` method:** + +```ruby +def render_segment(context, output, segment) + # Recording hook - loop enter + if (recorder = context.registers[:recorder]) + recorder.for_enter(@collection_name.to_s) + end + + for_stack = context.registers[:for_stack] ||= [] + length = segment.length + + context.stack do + loop_vars = Liquid::ForloopDrop.new(@name, length, for_stack[-1]) + for_stack.push(loop_vars) + + begin + context['forloop'] = loop_vars + + segment.each_with_index do |item, index| + # Recording hook - item binding + if (recorder = context.registers[:recorder]) + recorder.for_item(index, item) + end + + context[@variable_name] = item + @for_block.render_to_output_buffer(context, output) + loop_vars.send(:increment!) + + next unless context.interrupt? + interrupt = context.pop_interrupt + break if interrupt.is_a?(BreakInterrupt) + next if interrupt.is_a?(ContinueInterrupt) + end + ensure + for_stack.pop + + # Recording hook - loop exit + if (recorder = context.registers[:recorder]) + recorder.for_exit + end + end + end + + output +end +``` + +**Key Considerations:** +- Hook loop enter/exit for proper nesting tracking +- Bind each loop item to array index position +- Handle nested loops with proper stack management +- Maintain existing loop interrupt behavior + +### 2.4 File System Recording Hook (`lib/liquid/file_system.rb`) + +**Modification to `LocalFileSystem#read_template_file`:** + +```ruby +def read_template_file(template_path) + full_path = full_path(template_path) + raise FileSystemError, "No such template '#{template_path}'" unless File.exist?(full_path) + + content = File.read(full_path) + + # Recording hook via thread-local + if (recorder = Thread.current[:liquid_recorder]) + recorder.emit_file_read(template_path, content) + end + + content +end +``` + +**Key Considerations:** +- Use thread-local access since Context not available +- Record template path and full content +- Maintain existing error handling behavior +- Thread-local set/unset managed by main TemplateRecorder + +## Phase 3: Replay System + +### 3.1 Replayer Engine (`lib/liquid/template_recorder/replayer.rb`) + +```ruby +class Liquid::TemplateRecorder::Replayer + def initialize(recording_data, mode = :compute) + @data = recording_data + @mode = mode + @memory_fs = MemoryFileSystem.new(@data['file_system']) + @filter_index = 0 + end + + def render(to: nil) + + private + + def setup_context + def create_strict_strainer if @mode == :strict + def validate_engine_compatibility +end +``` + +**Replay Modes:** +- `:compute` - Use recorded data with current Liquid engine and filters +- `:strict` - Replay recorded filter outputs in sequence +- `:verify` - Compute and compare against recorded outputs + +**Key Responsibilities:** +- Parse recorded template source +- Build assigns from recorded variable tree +- Configure MemoryFileSystem with recorded files +- Handle mode-specific filter behavior +- Validate engine compatibility and warn on version mismatches + +### 3.2 Memory File System (`lib/liquid/template_recorder/memory_file_system.rb`) + +```ruby +class Liquid::TemplateRecorder::MemoryFileSystem + def initialize(file_contents_hash) + @files = file_contents_hash + end + + def read_template_file(template_path) + @files[template_path] or raise FileSystemError, "No such template '#{template_path}'" + end +end +``` + +**Key Responsibilities:** +- Serve recorded file contents during replay +- Maintain same interface as LocalFileSystem +- Raise appropriate errors for missing files + +### 3.3 Event Log (`lib/liquid/template_recorder/event_log.rb`) + +```ruby +class Liquid::TemplateRecorder::EventLog + def initialize + @drop_reads = [] + @filter_calls = [] + @loop_events = [] + end + + def add_drop_read(event) + def add_filter_call(event) + def add_loop_event(event) + + def finalize_to_assigns_tree +end +``` + +**Key Responsibilities:** +- Collect all events during recording +- Process events into minimal assigns tree +- Handle event deduplication and conflict resolution +- Generate arrays-of-maps for loop data + +## Phase 4: JSON Schema and Serialization + +### 4.1 JSON Schema Definition (`lib/liquid/template_recorder/json_schema.rb`) + +```ruby +{ + "schema_version": 1, + "engine": { + "liquid_version": "x.y.z", + "ruby_version": "3.x", + "settings": { + "strict_variables": false, + "strict_filters": false, + "error_mode": "lax" + } + }, + "template": { + "source": "template source code", + "entrypoint": "templates/product.liquid", + "sha256": "content hash" + }, + "data": { +

"snippets/variant.liquid": "template content", + "sections/product.liquid": "template content" + }, + "filters": [ + { + "name": "append", + "input": "base string", + "args": ["suffix"], + "output": "base stringsuffix", + "location": { "template": "product.liquid", "line": 10 } + } + ], + "output": { + "string": "final rendered output" + }, + "metadata": { + "timestamp": "2025-07-30T00:00:00Z", + "recorder_version": 1 + } +} +``` + +**Validation Rules:** +- Only scalars, arrays, and maps in `data.variables` +- All file paths relative to template root +- Filter log maintains call order +- Schema version compatibility checking + +### 4.2 Serialization Implementation + +```ruby +class Liquid::TemplateRecorder::JsonSchema + def self.serialize(recorder) + def self.deserialize(json_string) + def self.validate_schema(data) + + private + + def self.ensure_serializable(obj) + def self.calculate_template_hash(source) +end +``` + +**Key Responsibilities:** +- Ensure only serializable types in output +- Generate stable, pretty-printed JSON +- Validate schema compliance +- Handle version compatibility + +## Phase 5: Testing and Integration + +### 5.1 ThemeRunner Integration + +**Test Helper Methods:** + +```ruby +def record_theme_test(test_name, filename = nil) + filename ||= "/tmp/#{test_name.gsub('/', '_')}.json" + Liquid::TemplateRecorder.record(filename) do + ThemeRunner.new.run_one_test(test_name) + end + filename +end + +def replay_and_compare(recording_file, mode = :compute) + replayer = Liquid::TemplateRecorder.replay_from(recording_file, mode: mode) + replayer.render +end +``` + +### 5.2 Test Coverage Plan + +**Unit Tests:** +- TemplateRecorder API (record/replay) +- Recorder event collection +- BindingTracker object mapping +- EventLog finalization +- JSON schema validation +- MemoryFileSystem behavior + +**Integration Tests:** +- ThemeRunner recording/replay cycles +- Complex nested template scenarios +- Multiple loop nesting +- Filter chain recording +- Include/render tag behavior +- Error handling and edge cases + +**Performance Tests:** +- Recording overhead measurement +- Memory usage during large template recording +- Replay performance vs original render +- JSON file size for complex templates + +### 5.3 Edge Case Handling + +**Complex Scenarios:** +- Deeply nested loops (variants.images.tags) +- Dynamic include paths +- Conditional filter chains +- Complex property access chains +- Mixed scalar/object property reads +- Loop variable shadowing +- Include/render with different file systems + +**Error Conditions:** +- Invalid JSON schema +- Missing recorded files during replay +- Filter signature changes between record/replay +- Template parsing errors +- Memory/resource limit violations +- Version compatibility issues + +## Phase 6: Documentation and Examples + +### 6.1 API Documentation + +- Comprehensive RDoc for all public methods +- Usage examples for common scenarios +- Mode comparison

‘S’ PERFORMANCE

Producing 170hp (125kW) and with a dry weight of just 169kg (372.6lb), the new 1198 S now incorporates more World Superbike technology than ever before by taking the 1198 motor and adding top-of-the-range suspension, lightweight chassis components and a true racing-style traction control system designed for road use.

The high performance, fully adjustable 43mm Öhlins forks, which sport low friction titanium nitride-treated fork sliders, respond effortlessly to every imperfection in the tarmac. Beyond their advanced engineering solutions, one of the most important characteristics of Öhlins forks is their ability to communicate the condition and quality of the tyre-to-road contact patch, a feature that puts every rider in superior control. The suspension set-up at the rear is complemented with a fully adjustable Öhlins rear shock equipped with a ride enhancing top-out spring and mounted to a single-sided swingarm for outstanding drive and traction. The front-to-rear Öhlins package is completed with a control-enhancing adjustable steering damper.
