# Cowyo...

_...is the Collection of Online Words You Open._

This tool is supposed to make sharing online notes and lists fast and easy. To jot a note, simply load the page at [`/`](http://cowyo.com/) and write. The url will redirect to an easy-to-remember name that you can use to reload the page at anytime, anywhere. (You can use any url you want too: [`/AnythingYouWant`](http://cowyo.com/AnythingYouWant)). No need to press save, it will automatically save when you stop writing.

You can also write your notes in [Markdown](https://daringfireball.net/projects/markdown/) and then render your page by adding `/view`. For example, the page `/about` is rendered at [`/about/view`](/about/view).

If you are writing a list and you want to tick off things really easily, just add `/list`. For example, after editing [`/grocery`](http://cowyo.com/grocery), goto [`/grocery/list`](http://cowyo.com/grocery/list). In this page, whatever you click on will be striked through and moved to the end. This is helpful if you write a grocery list and then want to easily delete things from it.

Math is supported using [Katex](https://github.com/Khan/KaTeX). Base64 images are supported [in img tags](https://stackoverflow.com/questions/1207190/embedding-base64-images) as well.

Be cautious about writing sensitive information in the notes as anyone with the URL has access to it. For more information, or if you'd like to edit the code, [use the github](https://github.com/schollz/cowyo).

**Powered by Raspberry Pi, Go, and NGINX**

# Install

To get started on your local network just do:

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

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

## Production server

I recommend using `NGINX` as middleware, as it will do caching of the static files for you. There is an example `NGINX` block in `install/`. To automatically install, on Raspberry Pi / Ubuntu / Debian system use:

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

Now the program starts and stops with

```
sudo /etc/init.d/cowyo start|stop|restart
```

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

```
@reboot /etc/init.d/cowyo start
```
