A lightweight personal wiki written in Racket. It stands at less than 200 LOC and its only dependency is Rackets "markdown"-package.

polkadot displays documents you have written in Markdown and links them to the tags you specified in the document header. There are no change logs or user accounts or similarly complex features---polkadot is meant as a simple personal wiki. As such it doesn't aim to replace your whole publishing tool chain, but to be a part of it.

Following this philosophy, documents are simply files. This makes it very easy to handle them in any way you want--edit them with your favorite editor, over SSH, FTP, or git. Since documents are cached, there's no huge I/O overhead. polkadot also automagically updates its index on filesystem changes.

Since it's a simple piece of software, polkadot is easy to install;

1. First you need to install the package "markdown" with raco: raco pkg install markdown
2. Now you should take a look at polkadot.rkt and change the configuration variables to your liking.
3. There's no further setup required, just write your documents and run the thing.

At start polkadot will index all files in documents/. It will continue to monitor this directory for any updated, added, or deleted files that end with .polka. Static files can be added to static/.

You can find an introduction to writing documents in introduction.polka.

You'll find what you're looking for at either Github or, if IRC is your thing in #polkadot on irc.freenode.net.
