# hubot-eavesdrop

A hubot script to perform actions when user-specified keywords are mentioned. Based on [eardropping.coffee](https://github.com/github/hubot-scripts/blob/master/src/scripts/eardropping.coffee).

See [`src/eavesdrop.coffee`](src/eavesdrop.coffee) for full documentation.

## Installation

In hubot project repo, run:

`npm install hubot-eavesdrop --save`

Then add **hubot-eavesdrop** to your `external-scripts.json`:

```json
["hubot-eavesdrop"]
```

## Sample Interaction

```
user1>> hubot when you hear slow clap do echo http://i.imgur.com/0mKXcg1.gif
user1>> slow clap
hubot>> http://i.imgur.com/0mKXcg1.gif

user1>> hubot stop listening for slow clap
hubot>> Okay, I will ignore slow clap.
```

Also supports regular expressions.

```
user1>> hubot when you hear slow\s?clap(ping)? do echo http://i.imgur.com/0mKXcg1.gif
user1>> slow clapping
hubot>> http://i.imgur.com/0mKXcg1.gif
user1>> slowclap
hubot>> http://i.imgur.com/0mKXcg1.gif
```

Multiple actions can be specified for a single keyword.

```
user1>> hubot when you hear slow clap do 1|echo congrats!; 2|echo http://i.imgur.com/0mKXcg1.gif
user1>> slow clap
hubot>> congrats!
hubot>> http://i.imgur.com/0mKXcg1.gif
```

To reduce channel noise, keywords only trigger events once every thirty seconds.
The length of this delay can be changed by setting a `HUBOT_EAVESDROP_DELAY` environment variable.
