NimblePublisher

Full example on GitHub

NimblePublisher ships with Makeup-based highlighting, but it also exposes a custom html_converter hook. That is the right integration point for Lumis.

Use MDEx as the markdown engine inside that converter. This is cleaner than post-processing HTML, and it keeps syntax highlighting inside the markdown renderer where it belongs.

Keep highlighters empty​

Do not configure NimblePublisher's built-in highlighters when Lumis owns code blocks.

use NimblePublisher,

  build: Post,

  from: Application.app_dir(:my_app, "priv/posts/**/*.md"),

  as: :posts,

  html_converter: MyApp.Blog.Markdown,

  highlighters: []

Add dependencies​

def deps do

  [

    {:nimble_publisher, "~> 1.0"},

    {:mdex, "~> 0.11"}

  ]

end

Custom converter​

defmodule MyApp.Blog.Markdown do

  def convert(_path, body, _attrs, _opts) do

    MDEx.to_html!(body,

      syntax_highlight: [

        formatter: {:html_inline, theme: "github_light"}

      ]

    )

  end

end

Multi-theme version​

MDEx.to_html!(body,

  syntax_highlight: [

    formatter: {:html_multi_themes,

      themes: [light: "github_light", dark: "github_dark"],

      default_theme: "light-dark()"}

  ]

)
