What

This is a node.js-based wikifier for TiddlyWiki formatted wikitext.

Rather than creating new code this code simply assembles the required parts from the TiddlyWiki core code repository along with the necessary bits of additional JavaScript. This means that as the TiddlyWiki core changes this code automatically keeps up to date.

By using jsdom and htmlparser with node, it is possible to simulate the browser environment that the wikifier would normally run in, and create some HTML output.

How

(The below is for OS X but should transliterate to other environments. It has also been tested on Ubuntu 12.04)

Install node.js and its package manager npm. If you are using brew that goes like this:

brew install node npm

Once you have npm, install grunt with:

npm install -g grunt-cli

Then install the project dependencies:

npm install

In the repo directory run:

grunt

This will get all the necessary TiddlyWiki code and concatenate it into dist/twikifier.js. The grunt test task is run after this and runs all the files in the test/files directory against twikifier via test/twikify/js.

The task also creates a distributable node application in bin/server.js.

Testing

From the test directory, you can try your own wikitext by piping data into twikify on STDIN:

node twikify.js --collection=<url for tiddler collection> \
    < /tmp/mysampledata.txt

or by giving the names of multiple files on the command line:

node twikify.js --collection=<url for tiddler collection> \
    /tmp/mysampledata.txt /tmp/someotherdata.txt

<url for tiddler collection> should be replaced with the url of a collection of tiddlers, in JSON, as found in TiddlyWeb. Things like:

http://cdent-test7.tiddlyspace.com/bags/cdent-test7_public/tiddlers
http://cdent-test7.tiddlyspace.com/recipes/cdent-test7_public/tiddlers

As the tool develops there will be other interfaces.

Testing the NPM Package Works

From the repo directory run:

npm pack

This will create a zipped tarball. Install this tarball as follows:

npm install -g twikifier-x.y.z.tgz

If all is well, twikifier will be available in your path. Run this to check twikifier works.

Releasing the NPM Package

Run:

grunt release

See this link for how this works.

Use with TiddlyWeb and Tiddlyspace

Install the TiddlyWeb plugin:

pip install -U tiddlywebplugins.twikified

Add the following to tiddlywebconfig.py:

'wikitext.default_renderer': 'tiddlywebplugins.twikified'

Install this package via NPM then run the twikifier server:

npm install -g twikifier
twikifier /tmp/wst.sock

Then start TiddlyWeb/Tiddlyspace

If you have connection problems after a restart, remove /tmp/wst.sock and try again.

To permantly run twikifier, see the next section.

Start-up Script

To have twikifier automatically run on start-up and to give more control over starting and stopping it:

Copy the file scripts/twikifier to /etc/init.d/

Test it can start and stop:

    sudo /etc/init.d/twikifier start
    sudo /etc/init.d/twikifier stop
    sudo /etc/init.d/twikifier restart

Enable the script to start-up automatically on boot:

    update-rc.d twikifier defaults

Credit goes to https://github.com/chovy/node-startup for this.

Socket File Location

By default, twikifier expects the socket file to live in /var/run/twikifier. Create this folder, making sure the user running twikifier can read/write:

mkdir /var/run/twikifier
chown user.user /var/run/twikifier

To use another location, add the absolute path as an argument to twikifier in the start-up script.

Why

TiddlyWeb and friends use WikklyText to do sever- side rendering of TiddlyWiki text to HTML. It works, but not great. It has long been thought that a transcoding of the TiddlyWiki wikifier would a) work better, b) be easier to extend and modify.
