Recipes

Cache parsers (CLI)

Find the cross-runtime guide to warming Lumis parsers.

Parser warm-up is a common operation across Lumis runtimes. See Warm up parsers for the non-blocking startup APIs, the CLI command, LUMIS_DATA_DIR, Elixir configuration, and the runtimes that do not need a parser cache.

Line Numbers

Number the lines Lumis renders, in HTML and in the terminal.

Highlight diffs

Render a unified diff with the code inside each hunk highlighted as its own language.
