consolidateProjectStyleLines static method

List<String> consolidateProjectStyleLines(AFCommandContext context, List<String> rawLines)

Utility which allows project styles to contain a + syntax that spreads a command out over multiple lines.

Implementation

static List<String> consolidateProjectStyleLines(AFCommandContext context, List<String> rawLines) {
  final result = <String>[];
  var idxLine = 0;

      if(params.length != 2) {
        throw AFException("Expected import project_styles/your-project-style, found '$rawLine'");
      }
      final importStylePath = params[1].split('/');
      final importStyle = context.readProjectStyle(importStylePath);
      final consolidated = consolidateProjectStyleLines(context, importStyle.buffer.lines);
      result.addAll(consolidated);
