parseSnippets static method

Future<bool> parseSnippets(String sourceSnippetsPath)

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

Implementation

static Future<bool> parseSnippets(String sourceSnippetsPath) async {
  try {
    // Read the source snippets
    final sourceSnippets = await _readJsonFile(sourceSnippetsPath);
    if (sourceSnippets == null) return false;

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

    // Path to snippets file
    final snippetsFilePath = path.join('.vscode', 'snippets.code-snippets');
    final snippetsFile = File(snippetsFilePath);

    Map<String, dynamic> existingSnippets = {};

    // If snippets file exists, read and parse it
    if (await snippetsFile.exists()) {
      final content = await snippetsFile.readAsString();
      existingSnippets = json.decode(content) as Map<String, dynamic>;
    }

    // Merge snippets, preserving existing ones unless overwritten
    sourceSnippets.forEach((key, value) {
      if (!existingSnippets.containsKey(key)) {
        existingSnippets[key] = value;
      }
    });

    // Write the updated content back to snippets file
    await snippetsFile.writeAsString(
      JsonEncoder.withIndent('  ').convert(existingSnippets),
    );

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