The script will detect tags with `class="language-plantuml"`, but you can change this by providing a second argument to `parsePlantumlCodeBlocks`.
#### Example: STL Preview
You can display STL file directly in Gitea by adding:
```html
<script>
function lS(src){
return new Promise(function(resolve, reject) {
let s = document.createElement('script')
s.src = src
s.addEventListener('load', () => {
resolve()
})
document.body.appendChild(s)
});
}
if($('.view-raw>a[href$=".stl" i]').length){
$('body').append('<link href="/Madeleine.js/src/css/Madeleine.css" rel="stylesheet">');
Promise.all([lS("/Madeleine.js/src/lib/stats.js"),lS("/Madeleine.js/src/lib/detector.js"), lS("/Madeleine.js/src/lib/three.min.js"), lS("/Madeleine.js/src/Madeleine.js")]).then(function() {
$('.view-raw').attr('id', 'view-raw').attr('style', 'padding: 0;margin-bottom: -10px;');
new Madeleine({
target: 'view-raw',
data: $('.view-raw>a[href$=".stl" i]').attr('href'),
path: '/Madeleine.js/src'
});
$('.view-raw>a[href$=".stl"]').remove()
});
}
</script>
```
to the file `templates/custom/footer.tmpl`
You also need to download the content of the library [Madeleine.js](https://jinjunho.github.io/Madeleine.js/) and place it under `custom/public/` folder.
You should end-up with a folder structucture similar to:
```
custom/templates
-- custom
`-- footer.tmpl
custom/public
-- Madeleine.js
|-- LICENSE
|-- README.md
|-- css
| |-- pygment_trac.css
| `-- stylesheet.css
|-- examples
| |-- ajax.html
| |-- index.html
| `-- upload.html
|-- images
| |-- bg_hr.png
| |-- blacktocat.png
| |-- icon_download.png
| `-- sprite_download.png
|-- models
| |-- dino2.stl
| |-- ducati.stl
| |-- gallardo.stl
| |-- lamp.stl
| |-- octocat.stl
| |-- skull.stl
| `-- treefrog.stl
`-- src
|-- Madeleine.js
|-- css
| `-- Madeleine.css
|-- icons
| |-- logo.png
| |-- madeleine.eot
| |-- madeleine.svg
| |-- madeleine.ttf
| `-- madeleine.woff
`-- lib
|-- MadeleineConverter.js
|-- MadeleineLoader.js
|-- detector.js
|-- stats.js
`-- three.min.js
```
Then restart gitea and open a STL file on your gitea instance.
