TiddlyWiki on Tahoe-Lafs

​TiddlyWiki is a client-side wiki written purely in HTML/CSS and JavaScript. ​Tahoe-LAFS is a decentralized, secure storage grid. These go together like chocolate and peanut butter! We call the result an Unhosted Wiki.

For a hands on introduction here is an ​Unhosted Wiki you can play with. Follow the link, edit the Unhosted Wiki, and click "Save Changes"! :-)

To Build a Tahoe-LAFS-Ready TiddlyWiki (Unhosted Wiki)

You'll need tahoe-lafs:

Set up a tahoe-lafs web gateway on a secure machine which is controlled only by you following the "​quickstart" and "​running" instructions.

Now that you have a tahoe-lafs gateway running (on a machine under your own control, like your laptop) the next step is to publish the tiddlywiki, through the gateway, onto the tahoe-lafs grid. To do this...

You'll need a tiddlywiki with a couple of plugins:

Use wget to get a copy of an empty tiddlywiki with the HTTPSavingPlugin and TahoePlugin already installed:

wget http://tahoe-lafs.org/source/tiddly_on_tahoe/trunk/tahoe_tiddly/wiki.html

(Note: starting with this empty file that comes preloaded with the plugins is just for convenience—if you already have a tiddlywiki document that you want to publish on a tahoe-lafs grid, you can simply add the HTTPSavingPlugin and TahoePlugin to your current file and then proceed with these instructions.)

You'll need to publish the tiddlwiki to the grid:

Use the CLI described under the ​running documentation.

You need a tahoe-lafs directory to put the tiddlywiki in. You could accomplish this by running the following steps in order, but it's preferable to put it together in a single command as demonstrated below.

Stepwise

One, running:

tahoe mkdir

generates such a directory and prints the write capability to it on sdout.

Two, running:

tahoe cp wiki.html write capability

publishes the wiki.html to the directory you created in the previous step. It's critical that the write capability is stored somewhere you can reliably get to, as it is the only way to get write-access the tiddlywiki. Since this is the case I recommend the following single step publication...

Combined:

tahoe cp wiki.html `tahoe mkdir | tee WRITECAPABILITY.txt`

You can now access your Unhosted Wiki via:

http://localhost:3456/`cat WRITECAPABILITY.txt`/wiki.html
