Hi,
I am trying to integrate reveal.js [1] in a convenient way, such that I can
use TiddlyWiki to edit and store the presentation slides, but then simply
launch it straight from the wiki. Aditionally I am considering an export
mode as well, for creating standalone versions.
While I still have various challenges to solve, I am currently stumped
trying to open a new window with the reveal.js library loaded together with
the slides. My idea was to use the existing `tm-open-window` message and a
custom template. However I am having trouble finding out how I could take
full control of the document being displayed in the new window.
While reading through `$:/core/modules/startup/windows.js` I am getting the
impression there is no way to actually just dump a template similar to
`$:/core/save/all` (which allows manipulating the entire document including
headers etc) into a new window. Am I missing something here?
Can anyone suggest a method I could use? I would like to use a template
tiddler which contains the entire document ( i.e. `<html><head>custom
headers...</head><body>slide tiddlers rendered through another
template...</body></html>`)
My current attempts have thus far only produced nested
`<html>...<body><html>..</html></body></html>` type documents which do not
display properly, for obvious reasons.
Since I was stumped using the existing `tm-open-window` message, I tried
writing a new message `tm-open-raw-window` similar to the original, but
without the surrounding document. However I was not able to find out how to
parse a template-tiddler to html to dump it into the window.
`$tw.wiki.renderTiddler("text/html",'templatename')` looked rather
promising, but raised an exception for my template:
```
$:/core/modules/utils/utils.js:548 Uncaught TypeError: Cannot read property
'length' of undefined
at Object.exports.parseTextReference
($:/core/modules/utils/utils.js:548:45)
at exports.list ($:/core/modules/filters/list.js:21:18)
at eval ($:/core/modules/filters.js:207:15)
at Object.$tw.utils.each
...
```
Making a wild guess here, judging by the call stack, it might have
something to do with the list widget in the template? Maybe missing the
reference to the `currentTiddler` containing the `list` field?
Part of the template:
```
<$list filter="[list{!!title}]" emptyMessage="No slides added yet"
template="$:/core/ui/ListItemTemplate"/>
```
So if anyone can tell me how to do this, this might also solve my problem.
:)
Cheers.
