Add a Bootstrap Migration Rule¶

Bootstrap rules are applied only when --bootstrap is passed. There are two categories: data attribute renames and CSS class renames.

Data attribute¶

Add to the bootstrap.data_attributes section of migration_config.yaml:

bootstrap:
  data_attributes:
    # ...existing entries...
    - old: "data-example="
      new: "data-bs-example="

Add to the bootstrap.css_classes section:

bootstrap:
  css_classes:
    # ...existing entries...
    - old: "old-class-name"
      new: "new-class-name"

CSS class replacements are matched as substrings within class="..." attribute values.

Add a test case to tests/test_pt_migrator.py and run:

uv run pytest tests/test_pt_migrator.py -v
