# Flask-MQTT
Flask Extension for the [MQTT protocol][1]. Basically it is a thin wrapper
around [paho-mqtt][0] and aimes to simplify MQTT integration in Flask. MQTT is a
machine-to-machine "Internet of Things" protocol and was designed for extremely
lightweight publish/subscribe messaging transport.
[![Documentation Status](https://readthedocs.org/projects/flask-mqtt/badge/?version=latest)](http://flask-mqtt.readthedocs.io/en/latest/?badge=latest) [![PyPI version](https://badge.fury.io/py/Flask-MQTT.svg)](https://badge.fury.io/py/Flask-MQTT) [![Travis CI](https://travis-ci.org/stlehmann/Flask-MQTT.svg?branch=master)](https://travis-ci.org/stlehmann/Flask-MQTT.svg?branch=master)
Find the documentation on [http://flask-mqtt.readthedocs.io][2].
## Features
* configuration via Flask config variables
* auto-connect on start of your web application
* publish and subscribe messages
* use callbacks for certain topics
* use one callback for all subscribed topics
## Installation
Simply install the package as usual via pip:
```bash
$ pip install flask-mqtt
```
## Usage
### Basic Setup
```python
from flask import Flask
from flask_mqtt import Mqtt
app = Flask(__name__)
app.config['MQTT_BROKER_URL'] = 'mybroker.com'
app.config['MQTT_BROKER_PORT'] = 1883
app.config['MQTT_USERNAME'] = 'user'
app.config['MQTT_PASSWORD'] = 'secret'
app.config['MQTT_REFRESH_TIME'] = 1.0 # refresh time in seconds
mqtt = Mqtt(app)
@app.route('/')
def index():
return render_template('index.html')
```
### Subscribe to a topic
To subscribe to a topic simply use `mqtt.subscribe()`. To make sure the
subscription gets handled correctly on startup place the subscription inside
an `on_connect()` callback function.
```python
@mqtt.on_connect()
def handle_connect(client, userdata, flags, rc):
mqtt.subscribe('home/mytopic')
```
To handle the subscribed messages you can define a handling function by
decorating it with `@mqtt.on_message()`.
```python
@mqtt.on_message()
def handle_mqtt_message(client, userdata, message):
data = dict(
topic=message.topic,
payload=message.payload.decode()
)
```
To unsubscribe do:
```python
mqtt.unsubscribe('home/mytopic')
```
Or if you want to unsubscribe all topics use `unsubscribe_all()`.
```python
mqtt.unsubscribe_all()
```
### Publish
To publish a message you can use the `publish()` method.
```python
mqtt.publish('home/mytopic', 'this is my message')
```
### Small publish/subscribe MQTT client

Jinja2
~~~~~~
Jinja2 is a template engine written in pure Python. It provides a
`Django`_ inspired non-XML syntax but supports inline expressions and
an optional `sandboxed`_ environment.
Nutshell
--------
Here a small example of a Jinja template::
{% extends 'base.html' %}
{% block title %}Memberlist{% endblock %}
{% block content %}
<ul>
{% for user in users %}
<li><a href="{{ user.url }}">{{ user.username }}</a></li>
{% endfor %}
</ul>
{% endblock %}
Philosophy
----------
Application logic is for the controller but don't try to make the life
for the template designer too hard by giving him too few functionality.
For more informations visit the new `Jinja2 webpage`_ and `documentation`_.

MarkupSafe
==========
Implements a unicode subclass that supports HTML strings:
.. code-block:: python
>>> from markupsafe import Markup, escape
>>> escape("<script>alert(document.cookie);</script>")
Markup(u'&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
>>> tmpl = Markup("<em>%s</em>")
>>> tmpl % "Peter > Lustig"
Markup(u'<em>Peter &gt; Lustig</em>')
If you want to make an object unicode that is not yet unicode
but don't want to lose the taint information, you can use the
``soft_unicode`` function. (On Python 3 you can also use ``soft_str`` which
is a different name for the same function).
.. code-block:: python
>>> from markupsafe import soft_unicode
>>> soft_unicode(42)
u'42'
>>> soft_unicode(Markup('foo'))
Markup(u'foo')
HTML Representations
--------------------
Objects can customize their HTML markup equivalent by overriding
the ``__html__`` function:
.. code-block:: python
>>> class Foo(object):
... def __html__(self):
... return '<strong>Nice</strong>'
...
>>> escape(Foo())
Markup(u'<strong>Nice</strong>')
>>> Markup(Foo())
Markup(u'<strong>Nice</strong>')
Silent Escapes
--------------
Since MarkupSafe 0.10 there is now also a separate escape function
called ``escape_silent`` that returns an empty string for ``None`` for
consistency with other systems that return empty strings for ``None``
when escaping (for instance Pylons' webhelpers).
If you also want to use this for the escape method of the Markup
object, you can create your own subclass that does that:
.. code-block:: python
from markupsafe import Markup, escape_silent as escape
class SilentMarkup(Markup):
__slots__ = ()
@classmethod
def escape(cls, s):
return cls(escape(s))
New-Style String Formatting
---------------------------
Starting with MarkupSafe 0.21 new style string formats from Python 2.6 and
3.x are now fully supported. Previously the escape behavior of those
functions was spotty at best. The new implementations operates under the
following algorithm:
1. if an object has an ``__html_format__`` method it is called as
replacement for ``__format__`` with the format specifier. It either
has to return a string or markup object.
2. if an object has an ``__html__`` method it is called.
3. otherwise the default format system of Python kicks in and the result
is HTML escaped.
Here is how you can implement your own formatting:
.. code-block:: python
class User(object):
def __init__(self, id, username):
self.id = id
self.username = username
def __html_format__(self, format_spec):
if format_spec == 'link':
return Markup('<a href="/user/{0}">{1}</a>').format(
self.id,
self.__html__(),
)
elif format_spec:
raise ValueError('Invalid format spec')
return self.__html__()
def __html__(self):
return Markup('<span class=user>{0}</span>').format(self.username)
And to format that user:
.. code-block:: python
>>> user = User(1, 'foo')
>>> Markup('<p>User: {0:link}').format(user)
Markup(u'<p>User: <a href="/user/1"><span class=user>foo</span></a>')
Markupsafe supports Python 2.6, 2.7 and Python 3.3 and higher.

Werkzeug
========
Werkzeug is a comprehensive `WSGI`_ web application library. It began as
a simple collection of various utilities for WSGI applications and has
become one of the most advanced WSGI utility libraries.
It includes:
* An interactive debugger that allows inspecting stack traces and source
code in the browser with an interactive interpreter for any frame in
the stack.
* A full-featured request object with objects to interact with headers,
query args, form data, files, and cookies.
* A response object that can wrap other WSGI applications and handle
streaming data.
* A routing system for matching URLs to endpoints and generating URLs
for endpoints, with an extensible system for capturing variables from
URLs.
* HTTP utilities to handle entity tags, cache control, dates, user
agents, cookies, files, and more.
* A threaded WSGI server for use while developing applications locally.
* A test client for simulating HTTP requests during testing without
requiring running a server.
Werkzeug is Unicode aware and doesn't enforce any dependencies. It is up
to the developer to choose a template engine, database adapter, and even
how to handle requests. It can be used to build all sorts of end user
applications such as blogs, wikis, or bulletin boards.
`Flask`_ wraps Werkzeug, using it to handle the details of WSGI while
providing more structure and patterns for defining powerful
applications.
Installing
----------
Install and update using `pip`_:
.. code-block:: text
pip install -U Werkzeug
A Simple Example
----------------
.. code-block:: python
from werkzeug.wrappers import Request, Response
@Request.application
def application(request):
return Response('Hello, World!')
if __name__ == '__main__':
from werkzeug.serving import run_simple
run_simple('localhost', 4000, application)

~~~~~
Click is a simple Python module that wraps the stdlib's optparse to make
writing command line scripts fun. Unlike other modules, it's based around
a simple API that does not come with too much magic and is composable.
In case optparse ever gets removed from the stdlib, it will be shipped by
this module.

# the discussion to issue1602 in the Python bug tracker.
#
# There are some general differences in regards to how this works
