Collections of Organized Words You Open

This is a self-contained wiki webserver that makes sharing easy and fast. The most important feature here is simplicity. There are many other features as well including versioning, page locking, self-destructing messages, encryption, math support, and listifying. Read on to learn more about the features.

Features

Simplicity. The philosophy here is to just type. To jot a note, simply load the page at / and just start typing. No need to press edit, the browser will already be focused on the text. No need to press save - it will automatically save when you stop writing. The URL at / will redirect to an easy-to-remember name that you can use to reload the page at anytime, anywhere. But, you can also use any URL you want, e.g. /AnythingYouWant. All pages can be rendered into HTML by adding /view. For example, the page /AnythingYouWant is rendered at /AnythingYouWant/view. You can write in HTML or Markdown for page rendering. To quickly link to /view pages, just use [[AnythingYouWnat]].

Listifying. If you are writing a list and you want to tick off things really easily, just add /list. For example, after editing /grocery, goto /grocery/list. In this page, whatever you click on will be struck through and moved to the end. This is helpful if you write a grocery list and then want to easily delete things from it.

Page locking. Pages can be locked by providing a password to prevent further editing. The whole version tree will still be available. Note: This is not available for list mode.

Automatic versioning. All previous versions of all notes are stored and can be accessed by adding ?version=X onto /view or /edit. If you are on the /view or /edit pages the menu below will show the most substantial changes in the history. Note, only the current version can be edited (no branching allowed, yet).

Self-destructing messages. You can write a message that will delete itself when a user loads it (in any view). Useful for transmitting sensitive information. To use, simply add a line somewhere that says only "self-destruct".

Security. HTTPS support is provided and everything is sanitized to prevent XSS attacks. Though all URLs are publicly accessible, you are free to obfuscate your website by using an obscure/random address (read: the site is still publicly accessible, just hard to find!). In addition to TLS support, you can PGP-encrypt your messages using a passphrase (Note: This will delete the version tree).

Keyboard Shortcuts. Quickly transition between Edit/View/List by using Ctl+Shift+E to Edit, Ctl+Shift+Z to View, and Ctl+Shift+L to Listify.

Admin controls. The Admin can view/delete all the documents by setting the -a YourAdminKey when starting the program. Then the admin has access to the /ls/YourAdminKey to view and delete any of the pages.

Math support. Math is supported with Katex using $\frac{1}{2}$ for inline equations and $$\frac{1}{2}$$ for regular equations.

Install

First install Go. Then continue.

To access locally...

Then, if you want to host on your local network just do:

git clone https://github.com/schollz/awwkoala.git
cd awwkoala
make
./awwkoala -p :8001 LOCALIPADDRESS

and then goto the address http://LOCALIPADDRESS:8001/

To access from anywhere...

For this you need to forward port 80 and get a DNS for your external address. I recommend using NGINX as middleware, as it will do caching of the static files for you.

sudo apt-get install nginx

There is an example NGINX block in install/. If you want to use SSL instead, follow the instructions in letsencrypt/README.md. To automatically install, on Raspberry Pi / Ubuntu / Debian system use:

git clone https://github.com/schollz/awwkoala.git
cd awwkoala
nano Makefile <--- EDIT this Makefile to include YOUR EXTERNAL ADDRESS
make && sudo make install

Now the program starts and stops with

sudo /etc/init.d/AwwKoala start|stop|restart

Edit your crontab (sudo crontab -e) to start on boot:

@reboot /etc/init.d/AwwKoala start

Usage

$ awwkoala --help
awwkoala: A Websocket Wiki and Kind Of A List Application
run this to start the server and then visit localhost at the port you specify
(see parameters).
Example: 'awwkoala localhost'
Example: 'awwkoala -p :8080 localhost:8080'
Example: 'awwkoala -db /var/lib/awwkoala/db.bolt localhost:8003'
Example: 'awwkoala -p :8080 -crt ssl/server.crt -key ssl/server.key localhost:8080'
Options:
  -a string
        key to access admin priveleges (default no admin priveleges)
  -crt string
        location of ssl crt
  -db string
        location of database file (default "/home/mu/awwkoala/data.db")
  -httptest.serve string
        if non-empty, httptest.NewServer serves on this address and blocks
  -key string
        location of ssl key
  -p string
        port to bind (default ":8003")

If you set the admin flag, -a you can access a list of all the current files by going to /ls/WhateverYouSetTheFlagTo.
