Migrate
Upgrade existing Lumis applications, custom formatters, and integrations.
Choose the guide for the code you're updating. Lumis packages have separate release numbers, so the guides are grouped by runtime or integration.
| Existing code | Guide |
|---|---|
| Elixir 0.6, or parser downloads from before 0.9 | Elixir upgrades |
| HTML line divs or helpers that return line terminators | HTML line markup |
| JavaScript-only custom parser and query definitions | JavaScript custom languages |
| MDEx with compiled-in grammars | MDEx parser packages |
The Rust autumnus crate | Autumnus to Lumis |
For a new project, start with Installation. The usage and formatter pages describe the current API; these guides explain what to change in an existing application.
