atlas-sdk 1.1.1

Python SDK to interact with atlas

atlas-sdk
===

Python SDK for the [atlas](https://github.com/atlassistant/atlas) assistant!

## Installation

### PIP

`pip install atlas-sdk`

### Source

`git clone` this repository and run `python setup.py install`.

If you're a developer, prefer the command `python setup.py develop`.

## Usage

### SkillClient

Used this class to defines a new skill that should respond to given intents. This client already take care of the skill discovery routine to make it available to **atlas**.

```python
import logging
from atlas_sdk import SkillClient, Intent, Slot, Env, Request

def handle_echo(request):
"""Handle echo request.

:type request: Request

"""

date = request.slot('date') # Returns the value of the 'date' slot if set

# The "date" variable will hold a single string or an array of strings if multiple values are found for the same slot.
# This is very usefull if you want to handle cases where the user can enter many values such as "rooms" when turning lights on.

if not date:
# Ask for user input. Once done, this handler would be called again
# If you pass a list as a second argument, a random element will be choose as the text, this make it
# easy for your skill to propose some variants
return request.ask('date', _('You should provide a date?!'))

# Show something in the channel from which this request has been started
request.show(_('Hello from echo! Env was %s') % request.env('A_USELESS_PARAMETER'), terminate=True)

if __name__ == '__main__':
logging.basicConfig(level=logging.DEBUG)

echo_skill = SkillClient(
name='Echo',
description='Respond to echo intent',
version='1.0.0',
intents=[
# Handle "echo" intent. When the NLU returns this intent, the agent will call this skill and our handler
Intent('echo', handle_echo, slots=[Slot('date')]),
],
env=[
# This parameter will be retrieved and made available in the Request argument in your handlers. This parameter is available on a per user basis so each user can have its own set of parameters
Env('A_USELESS_PARAMETER'),
],
)

echo_skill.run()
```

### ChannelClient

Used this tiny client to create your own Channel to communicate with **atlas**. A channel can be anything you want such as a Slack bot, a web client, a CLI, a sound system which may handle user inputs issued as voice commands.

## i18n

This SDK use the [standard python package](https://docs.python.org/3/library/i18n.html) to localize skills. A traditional workflow is as follow:

- Use `_('Your message text')` from your own code.
- Run `xgettext your_script.py -o messages.pot` to generates a translation model
- Copy the `.pot` file into a `.po` file representing your translation in the skill directory under `locale/<lang>/LC_MESSAGES`
- Generates a binary translation file with the command `msgfmt messages.po`
