Embedded HTML

This example keeps HTML in a separate source file and embeds it in the executable as a MoonBit string. It demonstrates how to maintain page content separately without requiring a runtime HTML file.

12_embed · Source files: main.mbt, hello.html, hello.mbt, moon.pkg

Behavior

The window loads the embedded resource through html(). The package prebuild rule produces hello.mbt from hello.html.

async fn main {
  @proton.html("12 embed", resource, width=800, height=600, debug=true)
  ..identifier("dev.proton.12-embed")
  .run_or_abort()
}

Implementation

resource is generated from hello.html by the package's embed prebuild rule. The runtime receives the same kind of string as the minimal example; it does not read hello.html from disk at launch.

Edit hello.html and rebuild. Do not edit generated hello.mbt. Embedding a document does not automatically embed every relative image or script it references; use an asset entry for a directory of resources.

Run

After completing source checkout and runtime setup, run from the repository root:

moon -C examples run 12_embed --target native

Limits and interpretation

Edit hello.html, not generated hello.mbt. Embedded HTML does not automatically include sibling files; use the sidecar example for separate JS/CSS.
