I think, this would be a good idea, if users wouldn't use it in the wrong 
way, which will cause support on our side.

While embedding unknown data as base64 is ok. Including an uncompressed 
word or excel file into a html document imo is an incredibly bad idea. So I 
vote for a  zip, gzip only approach.

Interesting. I think you're right, defaulting to base64 format might well
be better. As you say, the downside would only be that unknown text formats
would be unnecessarily base64 encoded. I've made a ticket:

https://github.com/Jermolene/TiddlyWiki5/issues/1521

I've also made a ticket for adding a download link for binary tiddlers:

https://github.com/Jermolene/TiddlyWiki5/issues/1522

Re: [tw] Re: Embed a ZIP for download?

2015-02-23 Thread Andreas Hahn 

Hi Jeremy,

thanks for the change in boot.js. I have a question though:

Wouldn't it be possible to handle all unkown MIME types as binary data ?
That would ensure that people could for example embed word or excel 
files or a bunch of other file types (at the expense of some txt/ascii 
based formats). I am not sure if that is a good idea, or if that is 
possible to implement since most other systems seem to access 
contentTypeInfo as hashmap.

Just to be clear, TW5 does indeed support binary tiddlers (images 
being a good example). You can drag a ZIP file into TW and the right 
thing happens. The limitation at the moment is that there's no 
built-in way to download the file afterwards. You can use something 
like the following code to create a download link for a binary tiddler:


\define download-inner(title)

\end

\define download(title)
<$set name="type" value={{$title$!!type}}>

However, the .ZIP file extension needs to be registered in boot.js 
before this will work:


$tw.utils.registerFileType("application/zip","base64",".zip");

I've commited ZIP support here:

Hi Stephan

Just to be clear, TW5 does indeed support binary tiddlers (images being a
good example). You can drag a ZIP file into TW and the right thing happens.
The limitation at the moment is that there's no built-in way to download
the file afterwards. You can use something like the following code to
create a download link for a binary tiddler:

\define download-inner(title)

download="download">Download "$title$"
\end

\define download(title)

$tw.utils.registerFileType("application/zip","base64",".zip");

Re: [tw] Re: Embed a ZIP for download?

2015-02-23 Thread Andreas Hahn 

Hey Stephan,

at the moment TW is incapable of handling binary files (i.e. zip files). 
Unless you want to make big changes to various parts of the core, I 
suggest you do the following:


1. Convert your .zip into a base64 string
2. Place it inside a plain text tiddler (for reference)
3. Place a specially crafted link pointing to the url: 
"data:application/zip;base64,"


That should initiate a file dowload onClick is is currently the easiest 
way of doing it. Of course you can imagine writing a widget that reads 
the tiddler and crafts such a link,
clicks it and removes the link (that is how the download saver does it), 
but you can manually craft the link as well.
