CLI

Use lumis highlight when you want highlighted output from a file or stdin.

Basic examples​

lumis highlight main.rs

lumis highlight index.js --theme dracula

lumis highlight index.js --formatter html-inline --theme dracula

Terminal output is the default formatter, so --formatter terminal is optional.

From stdin​

cat main.rs | lumis highlight --language rust

echo 'const x = 1' | lumis highlight --language javascript --formatter html-inline --theme dracula

Use --language when piping content with no filename hint.

Language selection​

  • provide --language when you already know the language
  • omit it when file extension, filename, or source content should drive detection
  • if detection fails, Lumis falls back to plaintext
lumis highlight main.rs

lumis highlight main.txt --language rust

Formatter selection​

lumis highlight main.rs --theme dracula

lumis highlight main.rs --formatter html-inline --theme dracula

lumis highlight main.rs --formatter html-linked

lumis highlight main.rs --formatter html-multi-themes --themes light:github_light --themes dark:github_dark

lumis highlight main.rs --formatter bbcode-scoped
