rohd_source_navigator

Shared Dart source-navigation models and utilities for ROHD debug tools, including the ROHD Schematic Viewer.

Installation

dart pub add rohd_source_navigator

For Flutter applications, use flutter pub add rohd_source_navigator.

API

For a complete runnable example, see example/main.dart.

• FlcData, FlcEntry, and FlcFrame: parse and look up file/line/column traces from v5/v6 FLC hierarchy JSON or embedded netlist trace attributes.
• SourceFrame and FrameCycler: represent source locations and cycle through a selection's frames.
• normalizePath and resolveCandidatePaths: prepare source paths for a host application's file resolution.
• DtdService and request encoding helpers: source-navigation communication for Dart Tooling Daemon integrations.

Import the complete API:

import 'package:rohd_source_navigator/rohd_source_navigator.dart';

Use focused imports for FLC data, source-navigation utilities, or DTD integration:

import 'package:rohd_source_navigator/flc_data.dart';
import 'package:rohd_source_navigator/source_navigator.dart';
import 'package:rohd_source_navigator/dtd_service.dart';

For example, look up a signal's source location:

import 'package:rohd_source_navigator/flc_data.dart';

void main() {
  final data = FlcData.fromJson({
    'version': 5,
    'files': ['lib/top.dart'],
    'modules': {
      'Top': {
        'tree': [
          ['0:42:5', 'result'],
        ],
      },
    },
  });

  final frames = data.lookupSignal('Top', 'result');
  print(frames?.first); // lib/top.dart:42:5 [rohd]
}

This is a Dart library, not an editor extension. Installing this package does not install or activate the ROHD VS Code extension or its separate TypeScript implementation.

Development

The package lives in packages/rohd_source_navigator in the ROHD repository. Run dart pub get, dart analyze, and dart test from that directory.
