Uiki: A simple academic wiki

Uiki (wee-kee) is a simple academic wiki which supports:

• MathJax for LaTeX formatting
• multimarkdown for markdown formatting
• git for page versioning/offline editing
• prettify for syntax highlighting
• htpasswd-style files for user authentication
• SSL-encrypted connections

To enable remote checkouts/editing and to avoid the risk of losing data due to upgrades, all uiki pages are stored in (markdown-formatted) plaintext.

For a page <name>, the content for that page will be (by default) in:

db/<name>/content.md

which is also easily editable by a text editor on the server.

This program serves as the motivation for my article on web programming in Racket.

Dependencies

• racket
• git
• multimarkdown
• sed
• htpasswd (bundled with Apache)
• openssl (if generating a key and cert)

Installation

There is no installation. Uiki runs in place.

Running

To run uiki, use:

make run

or directly with:

racket uiki.rkt

By default, it will be on port 8080, and the main page is /wiki/main.

After you start it, set your browser to:

http://localhost:8080/wiki/main

Configuration

Configuration parameters are in config.rkt.

By default, authentication is on, but SSL is off.

To generate config.rkt, run make config.rkt.

The first time the server runs, it will create a passwd file and ask you to create an admin account.

Adding users

You can add users with htpasswd by modifying passwd, but users must use SHA1-hashed passwords.

For example, in the application directory:

htpasswd -s passwd john

Enabling SSL

Run make certs to generate a private key and a self-signed certificate in the directory certs.

Then, modify the approriate entries in global.rkt to point to these, and set use-ssl? to #t.

Wiki syntax

You can link to new pages by enclosing their name in [[ and ]].

You can use the pipe [[target|text]] notation to redirect a within-wiki link.

Markdown syntax

Markdown syntax is supported by multimarkdown.

LaTeX syntax

Inline LaTeX syntax is supported with $-notation, as in $f(x)$.

Equation blocks are supported by surrounding LaTeX with \\[ and \\], as in:

\\[
 Z = \int_0^\infty g(x)d(x)
\\]

Syntax highlighting

You can render code with syntax highlighting in a fenced block by specifying the language, as in:

```javascript
function main () {
   printf("Running some code.")
}
```
