createSnippet method

AFCodeBuffer createSnippet(Object source, { AFSourceTemplateInsertions? extend, Map<AFSourceTemplateInsertion, Object>? insertions, })

Given a snippet and a set of insertions, returns a code buffer with the insertions replaced.

Implementation

AFCodeBuffer createSnippet(
  Object source, {
    AFSourceTemplateInsertions? extend,
    Map<AFSourceTemplateInsertion, Object>? insertions
  }
) {
  var fullInsert = this.coreInsertions;
  if(extend != null) {
    fullInsert = fullInsert.reviseOverwrite(extend.insertions);
  }
  if(insertions != null) {
    fullInsert = fullInsert.reviseOverwrite(insertions);
  }

  if(source is! AFSourceTemplate) {
    throw AFException("Expected AFSnippetSourceTemplate");
  }

  var effective = source.toBuffer(this, insertions: fullInsert.insertions);

 if(source is AFSnippetSourceTemplate) {
    // see if the source is overridden
  final originalPath = source.templatePath;
  final overridePath = this.findOverrideTemplate(originalPath);
  final hasOverride = overridePath != originalPath;
    if(hasOverride) {
      if(AFProjectPaths.generateFileExists(overridePath)) {
        effective = AFCodeBuffer.fromGeneratePath(overridePath);
      } else {
        // if the path changed, and the override path is not on the filesystem, see if it
        // is one of our predefined paths.
        if(hasOverride) {
          final overrideTemplate = findEmbeddedTemplateSnippet(overridePath);
          if(overrideTemplate == null) {
            throw AFException("The override ${joinAll(overridePath)} was not found on the file system, or in the AFTemplateRegistry, for ${joinAll(originalPath)}");
          }
          effective = overrideTemplate.toBuffer(this, insertions: fullInsert.insertions);
        }
      }
    }
 }

  return effective;
