MOTH Puzzle Format
|
|
===========
|
|
|
|
MOTH puzzles are HTML5 documents,
|
|
with optional metadata.
|
|
Puzzles may contain stylesheets and scripts,
|
|
or any other feature made available by HTML5.
|
|
|
|
Typically, a puzzle will be rendered in an `<object>` tag
|
|
in the MOTH client.
|
|
Some clients may copy over scripts, stylesheets,
|
|
and embed the puzzle's `<body>` in the page.
|
|
|
|
Within a puzzle directory,
|
|
the puzzle itself is named `index.html`.
|
|
|
|
|
|
MOTH Metadata
|
|
=============
|
|
|
|
Puzzles may contain metadata,
|
|
which can be used by MOTH clients to alter display of puzzles,
|
|
or provide additional information in the UI.
|
|
|
|
Metadata is provided in HTML `<meta>` elements,
|
|
with the `name` attribute specifying the metadata name,
|
|
and the `content` attribute specifying the metadata content.
|
|
Multiple elements with the same `name` are generally permitted.
|
|
|
|
Metadata names are defined in detail in
|
|
[MOTH Metadata](metadata.md).
|
|
|
|
For example, the following `<meta>` elements
|
|
could appear in the `<head>` section of a puzzle's HTML:
|
|
|
|
```html
|
|
<meta name="author" content="Neale Pickett">
|
|
<meta name="moth.answerhash" content="87bcc390">
|
|
<meta name="moth.answerhash" content="622fcbe8">
|
|
<meta name="moth.objective" content="Understand radix 8 (octal)">
|
|
```
|
|
|
|
|
|
Images, Attachments, Scripts, and Style Sheets
|
|
===================
|
|
|
|
Related files can be referenced directly in HTML.
|
|
Related files *should* be located in the same directory as `index.html`,
|
|
but situations may exist where it makes more sense
|
|
to locate a file in the parent directory.
|
|
|
|
Related files are not hidden:
|
|
they can be discovered with an http `PROPFIND` method.
|
|
|
|
For example, assuming `honey.jpg` exists in the same directory
|
|
as `index.html`, a standard `<img>` tag will work:
|
|
|
|
```html
|
|
<img src="honey.jpg"
|
|
alt="A clay jar with the word 'honey' printed on the front."
|
|
title="Honey jar">
|
|
```
|
|
|
|
Puzzle Events
|
|
==============
|
|
|
|
As HTML5 documents,
|
|
MOTH puzzles can communicate with the MOTH client
|
|
using HTML5 events.
|
|
|
|
setAnswer
|
|
--------
|
|
|
|
A MOTH Puzzle may advise the client to fill the answer field with text
|
|
by emitting an `setAnswer` custom event.
|
|
|
|
For example, the following code will advice the client to set the answer field to the string `bloop`:
|
|
|
|
```javascript
|
|
let answerEvent = new CustomEvent(
|
|
"setAnswer",
|
|
{
|
|
detail: {value: 'bloop'},
|
|
bubbles: true,
|
|
cancelable: true
|
|
},
|
|
)
|
|
document.dispatchEvent(answerEvent)
|
|
```
|
|
|
|
MOTH clients *should* listen for such events,
|
|
and fill the answer input field with the event's value.
|
|
Puzzles *must* provide the user with a copy/paste-able representation of the answer, in the event the event is not handled correctly by the client.
|
|
|
|
|
|
Example Puzzles
|
|
=========
|
|
|
|
Minimally Valid Puzzle
|
|
---------
|
|
|
|
This puzzle provides the absolute minimum required:
|
|
a title, and puzzle contents.
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<title>Counting</title>
|
|
<p>1 2 3 4 5 _</p>
|
|
```
|
|
|
|
|
|
Puzzle with metadata
|
|
-----------------
|
|
|
|
Typically, puzzles will provide metadata,
|
|
to enable client features such as "possibly correct" validation,
|
|
author display, learning objectives
|
|
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>Counting Sheep</title>
|
|
<meta name="author" content="Neale Pickett">
|
|
<meta name="moth.answerhash" content="089c7244">
|
|
<meta name="moth.answerhash" content="92837b4f">
|
|
<meta name="moth.objective" content="Recognize the difference between a sheep and a wolf">
|
|
<meta name="moth.objective" content="Count to a high number">
|
|
<meta name="moth.success.acceptable" content="Count using fingers">
|
|
<meta name="moth.success.mastery" content="Count using software tools, and provide answer in hexadecimal">
|
|
</head>
|
|
<body>
|
|
<p>🐑🐑🐑🐑🐑🐑🐑🐑🐺🐑🐑</p>
|
|
<p>How many sheep?</p>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
|
|
Puzzle with images, scripts, and style
|
|
---------------------------
|
|
|
|
Since they are rendered as HTML documents,
|
|
puzzles may include any HTML5 feature.
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>Basic Sight Reading</title>
|
|
<meta name="author" content="Neale Pickett">
|
|
<meta name="moth.answerhash" content="baabaa08">
|
|
<meta name="moth.objective" content="Play a tune provided in sheet music">
|
|
<meta name="moth.success.acceptable" content="Play the requested tune with no mistakes">
|
|
<link rel="stylesheet" href="style.css">
|
|
<script src="midi-transcriber.mjs" type="module"></script>
|
|
</head>
|
|
<body>
|
|
<p>
|
|
Using the provided sheet music,
|
|
play "May Had A Little Lamb" on your MIDI keyboard.
|
|
If you make a mistake,
|
|
press the "reset" button and start over.
|
|
</p>
|
|
<p>
|
|
Once you have played from start to finish with no mistakes,
|
|
paste the computed answer into the answer box.
