# Exercise Problems

Try to solve this problems by yourself or as a group.
If you need help ask your neighbor. 
If you still need help raise your hand and Alec or I will come over to help.

Good Luck!


I'm throwing a party and this is my address book:

```eve
commit @party
 [#person name:"Ruben"]
 [#person name:"Jim"]
 [#person #vegetarian name:"John"]
 [#person name:"Terry"]
```


### Help I broke something!

No worries just use this link:
[Reset](https://goo.gl/dNniCN)
Don't actually just reload the page because Eve saves things aggressively and sometimes it gets it wrong and reloading will just load back up that bad save data.


## 1. Bigger party, no Jim
Add more people to the @party database but make sure Jim is not invited to the party and list out the people in the party.

```eve disabled
search @party
 x = "No one"
bind @browser
 [#div text:x]
```


Hint: How did we exclude Ruben in the tutorial?

## 2. No vegetarians
Everyone is who is **NOT** a vegetarian is invited and list out the people in the party.

```eve disabled
search @party
 x = "No one"
bind @browser
 [#div text:x]
```


Hint: Think about what tags actually are.


## 3. Combine Parties
Make your own party with the database `@yourParty` and invite people from the party and yourParty databases. But still don't invite Jim and **ONLY** invite vegetarians and list out the people in the party.


```eve disabled
commit @yourParty
```

```eve disabled
search
 x = "No one"
bind @browser
 [#div text:x]
```


Hint: Are you looking in the right databases?


## Final Thoughts
Thanks so much for attending this talk.

If you could take a little bit of time to fill out a quick survey about Eve that I will share with the community in order to help improve Eve.
[Survey](https://goo.gl/forms/5q48rzTe5UlQKTT22)

I hope it's given you the confidence to continue to learn Eve on your own.
The next place to go is to look at other examples of [Eve](http://play.witheve.com) and start playing around.

If you have any Eve questions in the future feel free to ask the [community](https://groups.google.com/forum/#!forum/eve-talk). 
Also join Alec and I in the [Code & Supply Eve Slack channel](http://www.codeandsupply.co/chat)
