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 [`/`](http://cowyo.com/) 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 [`/`](http://cowyo.com/) 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`](http://AwwKoala.com/AnythingYouWant). All pages can be rendered into HTML by adding `/view`. For example, the page [`/AnythingYouWant`](http://cowyo.com/AnythingYouWant) is rendered at [`/AnythingYouWant/view`](http://cowyo.com/AnythingYouWant/view). You can write in HTML or [Markdown](https://daringfireball.net/projects/markdown/) for page rendering. To quickly link to `/view` pages, just use `[[AnythingYouWnat]]`.

<br>

**Listifying**. If you are writing a list and you want to tick off things really easily, just add `/list`. For example, after editing [`/grocery`](http://AwwKoala.com/grocery), goto [`/grocery/list`](http://AwwKoala.com/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.

<br>

**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.

<br>

**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).

<br>

**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`".

<br>

**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](https://github.com/Khan/KaTeX) using `$\frac{1}{2}$` for inline equations and `$$\frac{1}{2}$$` for regular equations.



# Install

First [install Go](https://golang.org/doc/install). 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](https://www.duckdns.org/). I recommend using `NGINX` as middleware, as it will do caching of the static files for you.

```bash
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`.
