parseTasks static method

Future<bool> parseTasks(String sourceTasksPath)

Parses and merges tasks from a source file into the .vscode/tasks.json file. If the tasks.json file doesn't exist, it creates a new one. Returns true if successful, false if there was an error.

Implementation

static Future<bool> parseTasks(String sourceTasksPath) async {
  try {
    // Read the source tasks
    final sourceTasks = await _readJsonFile(sourceTasksPath);
    if (sourceTasks == null) return false;

    // Ensure we have a list of tasks from the source
    final List<Map<String, dynamic>> newTasks =
      (sourceTasks['tasks'] as List).cast<Map<String, dynamic>>();

    // Get or create .vscode directory
    final vscodeDir = Directory('.vscode');
    if (!await vscodeDir.exists()) {
      await vscodeDir.create();
    }

    // Path to tasks.json
    final tasksFilePath = path.join('.vscode', 'tasks.json');
    final tasksFile = File(tasksFilePath);

    Map<String, dynamic> existingContent;
    List<Map<String, dynamic>> existingTasks = [];

    // If tasks.json exists, read and parse it
    if (await tasksFile.exists()) {
      final content = await tasksFile.readAsString();
      existingContent = json.decode(content) as Map<String, dynamic>;
      existingTasks = (existingContent['tasks'] as List? ?? [])
          .cast<Map<String, dynamic>>();
    } else {
      existingContent = {
        'version': '2.0.0',
        'tasks': [],
      };
    }

    // Merge tasks, avoiding duplicates based on label
    final mergedTasks = _mergeTasks(existingTasks, newTasks);

    // Update the tasks in the existing content
    existingContent['tasks'] = mergedTasks;

    // Write the updated content back to tasks.json
    await tasksFile.writeAsString(
      JsonEncoder.withIndent('  ').convert(existingContent),
    );

    return true;
  } catch (e) {
    print('Error parsing tasks: $e');
    return false;
  }
