Publishing a Mudlet map online

This guide uses the mudlet-map-page GitHub Action. You point it at your Mudlet binary map (.dat) and it decodes the map, generates the host page, and deploys it to GitHub Pages — no hand-written HTML and no in-browser .dat decoding.

Requirements

• A GitHub account and a repository to hold your map.
• Your Mudlet map exported as a .dat file. In Mudlet: Options → Map → Save map (or saveMap() in the command line).

Steps

1. Add your map to a repository

Create a repository (or reuse an existing one) and commit your map file, e.g. maps/map.dat.

2. Add the workflow

Create the file .github/workflows/pages.yml with the following content, adjusting map-file and title to match your repo:

name: Map

on:
  push:
    branches: [main]
  workflow_dispatch:

permissions:
  contents: read
  pages: write
  id-token: write

jobs:
  pages:
    uses: Delwing/mudlet-map-page/.github/workflows/deploy-pages.yml@v1
    with:
      map-file: maps/map.dat
      title: My MUD Map

The permissions block is required. GitHub's default token is read-only, and id-token: write (needed for the Pages deploy) is never granted automatically, so the workflow fails at startup without it.

3. Enable GitHub Pages

In your repository go to Settings → Pages. In the Build and deployment section set Source to GitHub Actions.

4. Publish

Push to your main branch (or run the workflow manually from the Actions tab via Run workflow). When the run finishes it publishes the site and prints the URL in the run summary.

Your page is served at https://{repositoryOwner}.github.io/{repository}/

Customising the page

Pass extra options under with:. Common ones:

Input	Description
title	Page title shown in the browser tab and header.
logo	Logo image — a URL, or a file in your repo (copied into the site).
npc-url	NPC data file to make NPCs searchable (URL or repo file). Opt-in; without it, room-id search still works.
favicon	Favicon — a URL, or a repo file copied in as /favicon.ico.
lang	Document language and default UI language (e.g. pl, en).
credits-author	Author name shown in the help/credits modal.

See the project README for the full list of inputs (version pinning, extra assets, custom translations, etc.).
