* Messages can be handled concurrently
* Automatically reconnect to mattermost when connection is lost
* Python3 Support
* Mattermost >= 1.x

## Installation

```
pip install mattermost_bot
```

## Usage

### Registration

First you need create the mattermost email/password for your bot.

### Configuration

Then you need to configure the `BOT_URL`, `BOT_LOGIN`, `BOT_PASSWORD`, `BOT_TEAM` in a python module
`mattermost_bot_settings.py`, which must be located in a python import path.


mattermost_bot_settings.py:

```python
BOT_URL = 'http://<mm.example.com>/api/v3' # with 'http://' and with '/api/v3' path. without trailing slash. '/api/v1' - for version < 3.0
BOT_LOGIN = '<bot-email-address>'
BOT_PASSWORD = '<bot-password>'
BOT_TEAM = '<your-team>' # possible in lowercase
```

Alternatively, you can use the environment variable `MATTERMOST_BOT_URL`,
`MATTERMOST_BOT_LOGIN`, `MATTERMOST_BOT_PASSWORD`, `MATTERMOST_BOT_TEAM`.

or `MATTERMOST_BOT_SETTINGS_MODULE` environment variable, which provide settings module

```bash
MATTERMOST_BOT_SETTINGS_MODULE=settings.bot_conf matterbot
```


### Run the bot

Use the built-in cli script and point to your custom settings file.

```bash
MATTERMOST_BOT_SETTINGS_MODULE=mattermost_bot_settings matterbot
```

or you can create your own startup file. For example `run.py`:

```python
from mattermost_bot.bot import Bot


if __name__ == "__main__":
Bot().run()
```

Now you can talk to your bot in your mattermost client!



## Attachment Support

```python
from mattermost_bot.bot import respond_to


@respond_to('webapi')
def webapi_reply(message):
attachments = [{
'fallback': 'Fallback text',
'author_name': 'Author',
'author_link': 'http://www.github.com',
'text': 'Some text here ...',
'color': '#59afe1'
}]
message.reply_webapi(
'Attachments example', attachments,
username='Mattermost-Bot',
icon_url='https://goo.gl/OF4DBq',
)
# Optional: Send message to specified channel
# message.send_webapi('', attachments, channel_id=message.channel)
```

*Integrations must be allowed for non admins users.*

## Plugins

A chat bot is meaningless unless you can extend/customize it to fit your own use cases.

To write a new plugin, simply create a function decorated by `mattermost_bot.bot.respond_to` or `mattermost_bot.bot.listen_to`:

- A function decorated with `respond_to` is called when a message matching the pattern is sent to the bot (direct message or @botname in a channel/group chat)
- A function decorated with `listen_to` is called when a message matching the pattern is sent on a channel/group chat (not directly sent to the bot)

```python
import re

from mattermost_bot.bot import listen_to
from mattermost_bot.bot import respond_to


@respond_to('hi', re.IGNORECASE)
def hi(message):
message.reply('I can understand hi or HI!')


@respond_to('I love you')
def love(message):
message.reply('I love you too!')


@listen_to('Can someone help me?')
def help_me(message):
# Message is replied to the sender (prefixed with @user)
message.reply('Yes, I can!')

# Message is sent on the channel
# message.send('I can help everybody!')
```

To extract params from the message, you can use regular expression:
```python
from mattermost_bot.bot import respond_to


@respond_to('Give me (.*)')
def give_me(message, something):
message.reply('Here is %s' % something)
```

If you would like to have a command like 'stats' and 'stats start_date end_date', you can create reg ex like so:

```python
from mattermost_bot.bot import respond_to
import re


@respond_to('stat$', re.IGNORECASE)
@respond_to('stat (.*) (.*)', re.IGNORECASE)
def stats(message, start_date=None, end_date=None):
pass
```


And add the plugins module to `PLUGINS` list of mattermost_bot settings, e.g. mattermost_bot_settings.py:

```python
PLUGINS = [
'mattermost_bot.plugins',
'devops.plugins', # e.g. git submodule: domain:devops-plugins.git
'programmers.plugins', # e.g. python package: package_name.plugins
'frontend.plugins', # e.g. project tree: apps.bot.plugins
]
```
*For example you can separate git repositories with plugins on your team.*


If you are migrating from `Slack` to the `Mattermost`, and previously you are used `SlackBot`,
you can use this battery without any problem. On most cases your plugins will be working properly
if you are used standard API or with minimal modifications.
