Embed a code excerpt

Workflow

Render a plaintext paste or line range in an embeddable HTML surface with theme and line-number controls.

When to use it

Use this when

A blog post, issue, or internal doc needs a live paste excerpt.
The content is plaintext and safe to render in another page.

Steps

Do this

Create a plaintext paste Embed refuses encrypted pastes; use the full viewer for client-managed decryption.
Select a bounded range Pass lines=10-40 to focus the embed. The route validates ranges and caps very large excerpts.
Set display options Use theme=system, light, or dark and linenumbers=0 when surrounding prose already names the lines.

Examples

Copyable commands

Iframe

<iframe
  src="https://pastebin.ca/2EREFnGBXq/embed?lines=10-40&theme=dark"
  title="Configuration excerpt"
  loading="lazy"
  style="width:100%;min-height:360px;border:0"
></iframe>

No line numbers

Operational notes

Keep in mind

Signed-url pastes require the same ?s= token on the embed URL.
Use raw URLs for machine reads; embed is meant for human-readable HTML.
