import { markdown2HTML, generateMaps } from 'dumbymap'
// Create container element
const container = document.createElement('div')
document.body.append(container)
// Convert markdown text into Semantic HTML
markdown2HTML(container, '# Heading\n\n`map\nid: foo\nuse: Maplibre\n`\n')
// Gernerate maps from code block

Dumbymap adds several features from contents of Semantic HTML:
Generated from Element fits CSS Selector :has(.language-map) (by default)
It generates maps by textContent in YAML format, done by [mapclay]
For example:
~~~markdown
`map`
use: Maplibre
width: 200px
use: Maplibre
width: 200pxGenerated from anchor element which:
1. With has link for document fragment.
2. With title starts from =>
3. The following text in title would be treated as CSS selector of target element
It shows leader-line to target element on hover, for example:
`markdown
.random-class"" class="text-primary hover:underline" target="_blank" rel="noopener noreferrer">link
link
`
Generated from anchor element which:
1. With has link for document fragment.
2. With title starts from =>
3. The following text of title would be treated as CSS selector of target element
Class name with-leader-line and doclink would be added to element.
It shows leader-line to target element on hover, for example:
`markdown
.random-class"" class="text-primary hover:underline" target="_blank" rel="noopener noreferrer">link
link
`
Generated from anchor element with geo URI scheme.
Class name with-leader-line and geolink would be added to element.
It show leader-line to coordinates in target map elements, for example:
`markdown
Taiwan
It changes behaviors by query parameters in link:
1. If xy is specified, GeoLink would use its value instead of value in geo URI schemeid
1. If is specified, GeoLink would only points to map with its value. Can use comma to add multiple idtype
1. If is specified, anchor on map changes appearance (now only support type=circle)
For example:
`html
Taiwan
After generateMaps(), the container has the following structure:
For each element:
* class="Dumby": Container of DumbyMap Contents. It uses attribute data-layout to switch layoutclass="SemanticHtml"
* : Container of Semantic HTMLclass="Showcase"
* : Container of map with class="focus". Some layouts use it to display focused mapclass="dumby-block"
* : Block contains part of contents of Semantic HTML.class="mapclay"
* : Map generated by [mapclay]
Dumbymap switch layouts by attribute data-layout of container. Most of the features are done by pure CSS.
You can add custom layout by options layouts. For example, the following code add a new layout sticky to stick Showcase at bottom right corner:
`css
.Dumby[data-layout='sticky'] {
max-width: 80em;
.Showcase {
display: block;
width: 20vw;
height: 40vh;
position: absolute;
right: 20px;
bottom: 20px;
background: red;
}
}
`
`js``
generateMaps(container, { layouts: "sticky" })
Result:

- leader-line
- plain-draggable
- markdown-it
- [mapclay]
