Welcome to Pastr
Pastr is an interactive help system bringing the web and Internet Relay Chat together.
Our goal is to supply a system where IRC users seeking assistance can request a link from the
Pastr irc bot and be able to paste text to that link. The text can be syntax highlighted into any
of our supported languages (163 to date) if you choose a language when pasting/editing. The IRC bot
will relay the link for others to view/edit your post to the IRC channel (or nickname) who you are seeking
assitance from. Each post is revision controlled, so edits do not overwrite, they make a new version.
Features
- Pastr bot on Freenode and Efnet, responds to .hitme or .pastr in public or private to provide a link
- Pastr website, to view and search pastes
- Arbitrary searching via url -> http://pastr.it/by/channel/linuxhelp/network/Efnet/subject/Pastr
- Current search filters: network (Freenode, Efnet), subject, nickname, channel
- Syntax Highlighting for 163 different languages (and configuration files)
- Section handling (/^##\\s+\\w.*$/ adds a section to a paste)
- Ability to annotate pastes
- Plain text, auto-filename view. If the post view is http://pastr.it/100, then you may use a tool such as
wget http://pastr.it/100/grub-install.txt
to download the plain text contents of the paste as a file locally. The filename you choose is arbitrary, so long as it
starts with a word (/^\w/)
Hints
- xclip is a great helper for pasting text files.
xclip < /etc/fstab
Would read the contents from /etc/fstab into your X paste buffer. Then you just middle click on the paste body to paste /etc/fstab to Pastr.
- How do I just make a new paste on the web? 1: Install the pastr_it gem. 2: Register with pastr on Freenode. 3: Pastr It!
Roadmap
- List of posts (recent, yours, all, etc)
- Site theme and style redo with usability in mind
- Usability features: quick post without irc (see Admin for details), langauge names, clean up forms
- Different styles/themes/colors for paste view
- Commentable (annotatable) Posts
- Searchable Posts
- User Requested Features (get your requests to trey or death_syn or manveru or bougyman or jvaughn)
(stricken items are complete)

"True unemployment is around 21.7% (near depression-era rate) according to Shadowstats.com. Furthermore, says John Williams of Shadowstats.com, the M3 money supply reported for June 15, 2010 shows a negative 5.91% drop, the steepest decline in the M3 since the 1930s banking crisis. (The M3 is the broadest measure of money. It includes currency, checking and savings accounts, large time deposits, institutional money market mutual fund balances.)
Ee-gads! By two measures the economy is sinking, not growing."

Adding items at the end and at the beginning of the Scroller's Buffer is possible with Adapter.append and Adapter.prepend methods respectively. They have the following object-arguments:
{{ appendArgumentsDescription }}
{{ prependArgumentsDescription }}
The items parameter is an array of items we want to add, eof/bof params provide virtualization, decrease/increase define index strategy. Here we deal with only items parameter, other params are considered in the next demo. Both append and prepend methods act in the same way, so let's discuss prepend.
In this demo we have 20 items on start, 5 of them (95-99) are invisible on the backward direction. By pushing "Prepend" button we want to add 4 (which is the input value) new items to the top of the list. After they are prepended, they become visible when scrolling up. The Scroller accurately injects prepended items into its Buffer consisting of 95-114 rows initially, so 1-4 new items temporary take place of items with indexes 91-94.
But if we scroll away and make '90s items invisible and removed from the viewport, and then scroll back, we will realise that nothing changes: "new" items are gone and the old 91-94 items returned to initial position. The point is that the changes we provide via Adapter over the internal Scroller's Buffer don't affect the external Datasource we implemented on the Component level. This is the end app developer responsibility to take care of the data consistency during manual updates such as append, prepend, insert, remove, etc: the Datasource.get must provide correct data, while the Scroller maintains indexes. The next sample provides one of the approach of consistent Datasource implementation with Adapter.append and Adapter.prepend methods usage.


This document is aimed at everyone working in the NanoSafety Cluster.
The eNanoMapper ontology is developed to be used as common language for the nanosafety community [[Hastings2015]]. The ontology contains terms for, for example, titanium dioxide and zinc oxide, but the encourage the data and knowledge exchange for the OECD nanomaterials, we have added them to the ontology specifically.
The below table does not show where in the hierarchy the terms are found This can be looked up by clicking the eNanoMapper IRI link. The links provided for the ontology IRIs point to BioPortal [[Noy2009]], which will show the superclasses, which are more general concepts.
The below table gives the ontology IRIs for each of the OECD nanomaterials. Clear from the mapping IRIs is how the eNanoMapper ontology [[Hastings2015]] builds on the efforts from the NanoParticle Ontology [[Thomas2011]] and ChEBI ontology [[Hastings2012]].

[docs]class LazyModuleMixin:
r"""A mixin for modules that lazily initialize parameters, also known as "lazy modules."
.. warning:
Lazy modules are an experimental new feature under active development,
and their API is likely to change.
Modules that lazily initialize parameters, or "lazy modules",
derive the shapes of their parameters from the first input(s)
to their forward method. Until that first forward they contain
:class:`torch.nn.UninitializedParameter` s that should not be accessed
or used, and afterward they contain regular :class:`torch.nn.Parameter` s.
Lazy modules are convenient since they don't require computing some
module arguments, like the :attr:`in_features` argument of a
typical :class:`torch.nn.Linear`.
After construction, networks with lazy modules should first
be converted to the desired dtype and placed on the expected device.
This is because lazy modules only perform shape inference so the usual dtype
and device placement behavior applies.
The lazy modules should then perform "dry runs" to initialize all the components in the module.
These "dry runs" send inputs of the correct size, dtype, and device through
the network and to each one of its lazy modules. After this the network can be used as usual.
>>> class LazyMLP(torch.nn.Module):
... def __init__(self):
... super().__init__()
... self.fc1 = torch.nn.LazyLinear(10)
... self.relu1 = torch.nn.ReLU()
... self.fc2 = torch.nn.LazyLinear(1)
... self.relu2 = torch.nn.ReLU()
...
... def forward(self, input):
... x = self.relu1(self.fc1(input))
... y = self.relu2(self.fc2(x))
... return y
>>> # constructs a network with lazy modules
>>> lazy_mlp = LazyMLP()
>>> # transforms the network's device and dtype
>>> # NOTE: these transforms can and should be applied after construction and before any 'dry runs'
>>> lazy_mlp = mlp.cuda().double()
>>> lazy_mlp
LazyMLP( (fc1): LazyLinear(in_features=0, out_features=10, bias=True)
(relu1): ReLU()
(fc2): LazyLinear(in_features=0, out_features=1, bias=True)
(relu2): ReLU()
)
>>> # performs a dry run to initialize the network's lazy modules
>>> lazy_mlp(torch.ones(10,10).cuda())
>>> # after initialization, LazyLinear modules become regular Linear modules
>>> lazy_mlp
LazyMLP(
(fc1): Linear(in_features=10, out_features=10, bias=True)
(relu1): ReLU()
(fc2): Linear(in_features=10, out_features=1, bias=True)
(relu2): ReLU()
)
>>> # attaches an optimizer, since parameters can now be used as usual
>>> optim = torch.optim.SGD(mlp.parameters(), lr=0.01)
A final caveat when using lazy modules is that the order of initialization of a network's
parameters may change, since the lazy modules are always initialized after other modules.
For example, if the LazyMLP class defined above had a :class:`torch.nn.LazyLinear` module
first and then a regular :class:`torch.nn.Linear` second, the second module would be
initialized on construction and the first module would be initialized during the first dry run.
This can cause the parameters of a network using lazy modules to be initialized differently
than the parameters of a network without lazy modules as the order of parameter initializations,
which often depends on a stateful random number generator, is different.
Check :doc:`/notes/randomness` for more details.
Lazy modules can be serialized with a state dict like other modules. For example:
>>> lazy_mlp = LazyMLP()
>>> # The state dict shows the uninitialized parameters
>>> lazy_mlp.state_dict()
OrderedDict([('fc1.weight', Uninitialized parameter),
('fc1.bias',
tensor([-1.8832e+25, 4.5636e-41, -1.8832e+25, 4.5636e-41, -6.1598e-30,
4.5637e-41, -1.8788e+22, 4.5636e-41, -2.0042e-31, 4.5637e-41])),
('fc2.weight', Uninitialized parameter),
('fc2.bias', tensor([0.0019]))])
Lazy modules can load regular :class:`torch.nn.Parameter` s (i.e. you can serialize/deserialize
initialized LazyModules and they will remain initialized)
>>> full_mlp = LazyMLP()
>>> # Dry run to initialize another module
>>> full_mlp.forward(torch.ones(10, 1))
>>> # Load an initialized state into a lazy module
>>> lazy_mlp.load_state_dict(full_mlp.state_dict())
>>> # The state dict now holds valid values
>>> lazy_mlp.state_dict()
OrderedDict([('fc1.weight',
tensor([[-0.3837],
[ 0.0907],
[ 0.6708],
[-0.5223],
[-0.9028],
[ 0.2851],
[-0.4537],
[ 0.6813],
[ 0.5766],
[-0.8678]])),
('fc1.bias',
tensor([-1.8832e+25, 4.5636e-41, -1.8832e+25, 4.5636e-41, -6.1598e-30,
4.5637e-41, -1.8788e+22, 4.5636e-41, -2.0042e-31, 4.5637e-41])),
('fc2.weight',
tensor([[ 0.1320, 0.2938, 0.0679, 0.2793, 0.1088, -0.1795, -0.2301, 0.2807,
0.2479, 0.1091]])),
('fc2.bias', tensor([0.0019]))])
Note, however, that the loaded parameters will not be replaced when doing a "dry run" if they are initialized
when the state is loaded. This prevents using initialized modules in different contexts.

jQuery.event.drop provides drop events for jQuery.event.drag. By binding to a
drop event, callback functions will be called during the corresponding phase of the drag motion.
Drop Events
All drop events are called with the native event, an instance of jQuery.Drop, and jQuery.Drag. The following
drop events are supported:
dropinit - the drag motion is started, drop positions are calculated.
dropover - a drag moves over a drop element, called once as the drop is dragged over the element.
When you bind on a drop event, it adds that element to the list of rootElements.
RootElements might be drop points, or might have delegated drop points in them.
When a drag motion is started, each rootElement is queried for the events listening on it.
These events might be delegated events so we need to query for the drop elements.
With each drop element, we add a Drop object with all the callbacks for that element.
Each element might have multiple event provided by different rootElements. We merge
callbacks into the Drop object if there is an existing Drop object.
Once Drop objects have been added to all elements, we go through them and call draginit
if available.

A drop instance supports the following methods:
If you are adding drop points after the start of a drag motion, call [$.Drop.compile] to re-calculate all drop points.

Here's how to listen for when a drag moves over a drop:

If you don't know what is resque or redis, take a look at their official website :
This tool is intended to facilitate your life by making interfacing with php-resque more easier and more friendly.
You should already have some knowledge about php-resque, and have php-resque installed and running.
I'll assume in this tutorial that you have sufficient knowledge to start a worker normally with php-resque.
Fresque is a command line tool. But instead of starting a worker with
QUEUE=file_serve php resque.php
you do
fresque start -q file_serve
It's more friendly, and provides more options, like restart
, stop
, etc …
Php-resque, and resque, by default doesn't provide an out-of-the-box way to stop your workers.  With Fresque, you'll enjoy stopping and restarting your workers at gogo.
A fresque.ini file is provided to set your workers default parameters, and other options used by fresque, such as redis connection options.
it's well documented, and you shouldn't have difficulties filling it.
Some examples are available at the end of this page.
It's often wise to start by adding the fresque executable to your system path. You then just call
fresque <command>
Or if you didn't add it,
cd /path/to/the/resque/executable
./fresque <command>
There's a bunch of interesting commands available :
To start a new resque worker. Be default, it will use the default configuration defined in you fresque.ini for the queue name, the pooling frequency, and other various options. You can override all of them with an option flag. Available options :
-u
or--user
: User running the php process. Should be the user running your php application, usually www-data for apache. Using a different user could lead to permissions problems in some cases.
-q
or--queue
: A list of queues name, separated with a comma.
-i
or--interval
: Pooling frequency. Number of seconds between each pooling.
-n
or--workers
: Number of workers working on the same queue. Uses pcntl to fork the process, ensure that you PHP is compiled with it.
-l
or--log
: Absolute path to the log file. You can set a different log for each worker. The--user
must have permission to read and write to that file (and the parent folder, since the file will be created if non-existent).
For creating multiple queues with different options, just run start
again.
To shutdown all resque workers. Will wait for all jobs to finish, then shutdown all workers.
-f
or--force
: Force shutdown, without waiting for the jobs to finish. All jobs will fail.
To restart all the workers, with their previous settings.
To start a batch of pre-defined queues (set in your configuration file). See fresque.ini for more informations.
Display total number of failed/processed jobs, as well as various stats for each workers.
Tail the workers' logs.
Enqueue a job. Should be used for testing purpose only. Takes 3 arguments :
queuename : Name of the queue you will enqueue this job to
jobclass : Name of the class that will perform the job, and that your application autoloader will have to load.
arguments : Other arguments you want to pass to your jobs.
Successfully enqueuing a job does not means it will perform it successfully. See notes
Test your configuration. If no options provided, it will test you fresque.ini. It accepts all options, to let you test them.
Finally, there's some global options, that can be used for all commands. Default value in your config file will be used unless you use these.
-s
or--host
: Redis hostname
-p
or--port
: Redis port
-b
or--lib
: Absolute path to the php-resque library. Used when you already have your own, and don't want to use the one shipped with fresque.
-c
or--config
: Absolute path to your config file. You can use different config for different workers. Default one is fresque.ini, in the same directory as the executable.
-a
or--autoloader
: Absolute path to your application entry point. Usually, it should be the file that will autoload all your job classes.
Let's start a worker with the default settings defined in the config file (fresque.ini)
fresque start
Let's start another worker, named activity, with a pooling frequency of 1 second. Also. I want two workers working on this queue.
fresque start -q activity -i 1 -n 2
Then, I want another worker, that will work on the queues default and activity at the same time.
fresque start -q default,activity
Oh wait, I have another resque on another redis server. I want to log its activities in an other log file : remote.log
fresque start -s <IP_ADDRESS> -p 6390 -q myspecialqueue -l /path/to/remote.log
If you have your config file elsewhere, and your php-resque lib elsewhere also
fresque start -c /path/to/my-config.ini -b /path/to/my/custom/php-resque
To view stats of your workers (to know how many you have, processed/failed jobs count, uptime)
fresque stats
It should output something like that
PHPResque Statistics
Jobs Stats
Processed Jobs : 18617
Failed Jobs : 319
Workers Stats
Active Workers : 6
Worker : KAMISAMA-MAC.local:33197:default
- Started on : Wed May 16 00:33:04 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
Worker : KAMISAMA-MAC.local:33207:default
- Started on : Wed May 16 00:33:08 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
Worker : KAMISAMA-MAC.local:33215:myspecialqueue
- Started on : Wed May 16 00:33:10 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
Worker : KAMISAMA-MAC.local:33232:activity
- Started on : Wed May 16 00:33:16 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
Worker : KAMISAMA-MAC.local:33233:activity
- Started on : Wed May 16 00:33:16 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
Worker : KAMISAMA-MAC.local:33223:default,activity
- Started on : Wed May 16 00:33:13 EDT 2012
- Uptime : less than a minute
- Processed Jobs : 0
- Failed Jobs : 0
It's wise to do a stats
after doing a start
, to ensure that your workers has been successfully created. [See Notes]
Remember that you can use the global options (-s, -p etc …) with any command
fresque stop -c /path/to/my-config.ini -s <IP_ADDRESS>
Let's enqueue a job to the activity queue
fresque enqueue activity PageVisit 5 /index.php 158745693
php-resque will then run this job, by instanciating the class PageVisit, then calling the perform()
method with the arguments 5, /index.php and 158745693.
In order to instanciate the PageVisit class, php-resque should know where to find it. That should be done with you application autoloader (--include
)
Oh, and if you want to restart all your workers for whatever reasons
fresque restart
If you're finished, just
fresque stop
It'll spout something like that
Shutting down Resque Worker complete
Killing 6 workers ...
Killing 33197
Killing 33207
Killing 33215
Killing 33232
Killing 33233
Killing 33223
See notes if it says There were no active workers to kill … but you're sure there are some.
We've just created 6 workers, calling start
5 times (remember, the second start
create 2 workers with -n 2
). But there's a way to start all of them with only one command, useful when you have a lot of workers that you have to start each time.
Just set all your workers settings in the config file in the [Queues] section (walkthrough available in the config file), then start all of them with
fresque load
start
command with stats
Starting a worker with fresque just send a start command to php-resque, which will be running in another process. Thus, any error occuring with php-resque will not be escalated to fresque.
This happens when :
--user
) does not existsThese errors occured within php-resque in another process and can't be detected with fresque, which will still returned a success command. A way to confirm that your workers were successfully created is to call stats
, which will display a list of workers.
You can also read your logs, they give you more details as to where the script hanged.
test
A testing tool for testing your configuration file is provided, just call test
.
This will test the minimum requirements to run fresque :
This will not test the content of your application autoloader, so if there's something inside triggering a fatal error, fresque will not know, and return a success*, but the worker will fail to start, like we just said above.
You can test more than the settings inside your config file, by passing options. An option will override the setting defined in the config
fresque test -s <IP_ADDRESS> -p 6890
This will test your config file, but with the specified redis hostname and port.
You can also test an other config file
fresque test -c /my/other/config/file.ini
A test result will looks like
Testing configuration
Redis configuration .....OK
Redis server ............OK
Log File ................OK
PHPResque library .......OK
Application autoloader ..OK
Your settings seems ok
stop
command doesn't stop workersThis happens when you try to stop your workers, but it says There were no active workers to kill …. And a look with stats
will tell you that there are. This occurs when the --user
doesn't have sufficient permissions to kill the workers processes.
Logs tell you all you need to know about the issue of a job, and the current status of your php-resque workers. It tells you when a job is enqueued, when a job is about to being performed, and its issue (success/fail). It also display all php related errors that may occurs.
Check them frequently, as fresque doesn't capture those errors.
Fresque is a derivated works from my other plugin, cake-resque, a command line tool to manage php-resque, but inside cakephp console.
Very convenient, but limited to only cakephp framework. I wanted to release a tool that can work in any php environment. Fresque is more powerfull, since no more binded to a framework.

The web is organized around plain text and socket connections between computers. We can not ship the data as it is in our computer’s memory to the other computer for lots of reasons. What we do is translate it (encode it) in a predictable way. A common way on the web is “urlencoding”. Another type of encoding that has become populate in recent years is JSON. That’s the encoding style we’ll use most often in our API requests but for authentication we use “urlencoding”.
The final encode reference in our previous example was to ‘utf-8’. This refers to a character encoding. They way we represent symbols like letters or characters in other langauages like Danish, Hindi or Korean. JSON by specification expects to be ‘utf-8’
So in one case we encode our data into an expected layout and in another we explicitly encode it into a character representation. Both are important.

Class TranslationGridView<T1, T2>
Class implementing IGridView<T> by providing a function that translates values from one grid view with complex data types, to a grid view with simple data types. For a version that provides "set" functionality, see SettableTranslationGridView<T1, T2>.
Implements
Inherited Members
Namespace: SadRogue.Primitives.GridViews
Assembly: TheSadRogue.Primitives.dll
Syntax
public abstract class TranslationGridView<T1, T2> : GridViewBase<T2>, IGridView<T2>
Type Parameters
| Name | Description |
|---|---|
| T1 | The type of your underlying data. |
| T2 | The type of the data being exposed by the grid view. |
Remarks
This class is useful if the underlying representation of the data you are creating a grid view for is complex, and you simply need to map a complex data type to a simpler one. For example, you might implement the TranslateGet(Point, T1) function to extract a property from a more complex structure. If your mapping is very simple, or you do not wish to create a subclass, see LambdaTranslationGridView<T1, T2>.

Twilio Client iOS Quickstart
Overview
You want your iPad/iPhone/iPod Touch app to make and receive calls? There's an SDK for that!
Twilio Client for iOS is an Objective-C library that enables voice communications with landlines or other Twilio Client devices, including web browsers and other mobile devices.
Architecture
There are three major pieces in a Twilio Client app:
- Your iOS app that uses the
libTwilioClient.a
library to add Voice over IP features to your application. - A server-side application to grant a capability token to your Client app, and to orchestrate Twilio's telephony services using TwiML and Twilio's REST API. You'll use a TwiML Application to connect your iOS app to Twilio's cloud.
- Twilio's cloud services to connect your app to conference calls, IVR applications, and make calls to PSTN and SIP devices.
We'll walk you through each of these pieces in detail below. Let's get started.
Quickstart Tutorial
In this tutorial, we'll use the Twilio Client iOS and TwiML APIs to demonstrate how to make an outgoing call, receive an incoming call, and make calls between two Twilio Client instances.
This guide assumes you have familiarity with iOS and Objective-C concepts like View-Controllers, delegates, properties, and Objective-C object life cycle and memory management.
Prerequisites
- Install Xcode 6 with at least iOS SDK 8 or higher. Xcode may be obtained from the Mac App Store.
- Get set up as a registered iOS developer with valid Provisioning Profile(s) for any devices you will be testing with. For more information on provisioning devices, please refer to Apple's documentation Maintaining Identifiers, Devices, and Profiles.
- Get a Twilio Account SID and Auth Token to initiate calls from your iOS device. You will find these in your Account Dashboard. If you don't have an account, you can always sign up for a free trial account.
- In the example below, we'll setup a web server on the public Internet to host the server-side code for generating capability tokens and TwiML. The Quickstart below provides a sample python app deployed to Heroku for this purpose, but you can use whatever method for deploying a web server you like.
Let's get some of the server-side dependencies out of the way first.
Configure a Placeholder TwiML Application
Visit TwiML Apps in the Twilio Account Portal and click 'Create TwiML App'. Enter 'iOS Quickstart' as the app's Friendly Name and click 'Save'. Don't worry about the Voice and Messaging URLs yet–we'll fill them in shortly.
Once the application is saved, make note of its ApplicationSid (a long string like "APa4983020a0b29fb5db1b1dc68e322fbe"). We'll need this in the upcoming steps.
Setup the back-end Application Server
Next, we'll deploy a server to perform two functions:
- Provide capability tokens to our iOS client application.
- Serve up our TwiML application and/or make REST API calls to orchestrate Twilio's telephony services.
Quick Tour of the Application
The code for the Quickstart Tutorial server-side application can be found in the Server/
folder inside the SDK tarball. Feel free to open up server.py
and take a look. The app uses Python's Flask framework and exposes three endpoints:
/
generates TwiML to tell Twilio to play "Welcome to Twilio" whenever you place a call./call
generates TwiML to route calls to/from the PSTN and your iOS application./token
returns a capability token to your iOS application.
Deploying the Server
Now we need to make this application available via the public Internet. You can do this with either of the following methods, or another approach to deploy a web server you're comfortable with.
Option 1: Use Heroku
The easiest way to deploy the application is Heroku. To do this, do the following:
- Visit the Twilio Mobile Quickstart repository on Github and click the "Deploy to Heroku" button. If you don't have a Heroku account, you'll be led through the process to set one up.
- Once you've signed into Heroku, you'll be taken to a form to deploy the Quickstart application.
- Enter your Twilio Account Sid and your Twilio Auth Token as the ACCOUNT_SID and AUTH_TOKEN values, respectively.
- Enter the TwiML App Sid you created above as the value for APP_SID.
- Enter any caller ID that you've verified with your Twilio account in the CALLER_ID field.
- Click Create your application.
- Once Heroku finishes, open up a second tab and return to the configuration screen for your TwiML app. Enter your Heroku application's URL as the voice url for your application and save the change.
Option 2: Run Locally Using ngrok
With this method, you'll run Flask
on your local box and create a
publicly-addressable tunnel to it using ngrok.
- Open server.py and modify
ACCOUNT_SID
andAUTH_TOKEN
to match the values from your Twilio account. - Modify
APP_SID
to match the App Sid you created above. - Modify
CALLER_ID
to any caller ID that you've verified with your Twilio account. - Install all the required python dependencies by running
pip install -r requirements.txt
from theServer/
folder at the command line. - Download and install ngrok and setup a free ngrok account.
- Run
python server.py
to start the server. - Run
ngrok 5000
to open up a tunnel from the public Internet to your server. - Return to the configuration screen for your TwiML app and enter your ngrok application's URL as the voice URL for your application and save the change.
Testing your Server
To make sure your server deployed successfully, open a web browser and enter http://{your heroku app or ngrok address}/
and view source on the resulting page. If everything is working, you'll see some XML that looks like this:
<?xml version="1.0" encoding="UTF-8"?> <Response> <Say>Welcome to Twilio</Say> </Response>
This is a simple TwiML application that will play an announcement whenever you make a call from your iOS application.
Now that we have the server-side dependencies setup, let's get started on our iOS app. You can test the examples below in the iOS Simulator or on your device.
The Xcode Project
Please open HelloMonkey.xcodeproj
Xcode project in Quickstart
folder.
This project is based on "View-based Application" template for
iPhone that has already been configured to work with Twilio Client
library. Please see Frequently Asked Questions for details on
modifying an Xcode project to use Twilio Client.
The HelloMonkey app is very simple, presenting "Dial" and "Hangup"
buttons, and a text field for who the app should call. The user
interface elements have already been wired up to the
HelloMonkeyViewController
class in Interface Builder.
In this step, you'll fill in the code to give the app its behavior, learning how to use the Twilio Client iOS SDK in the process.
Creating a Device
The primary class for connecting to Twilio services from your app is
TCDevice
. This class represents a soft "device" that knows how to speak to Twilio services, coordinates service authorization with Twilio,
listens for incoming connections, and establishes outgoing connections.
An instance of this class is created using a "capability token",
described in the next section.
You'll use a TCDevice
to initiate outgoing calls and listen for incoming calls.
Let's create an instance and wire it up!
Add a member variable of type TCDevice
to HelloMonkeyViewController.m
like so:
HelloMonkeyViewController.m
#import "HelloMonkeyViewController.h" #import "TwilioClient.h" @interface HelloMonkeyViewController() { TCDevice* _phone; TCConnection* _connection; } @end
To initialize a device, you'll change the URL to point to your server's
/token
URL and pass the resulting string to
-initWithCapabilityToken:delegate:
.
Note: Make sure you swap in your back-end server's /token
URL for the sample URL in HelloMonkeyViewController
's viewDidLoad
method.
HelloMonkeyViewController.m
- (void)viewDidLoad { NSURL *url = [NSURL URLWithString:@"http://companyfoo.com/token"]; NSError *error = nil; NSString *token = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error]; if (token == nil) { NSLog(@"Error retrieving token: %@", [error localizedDescription]); } else { _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:nil]; } }
Making an HTTP request to the /token
endpoint returns a
capability token–a string that, when given to a TCDevice
in your iOS app,
grants it capabilities such as making outgoing calls or allowing incoming calls.
Capability tokens are an important part of Twilio Client, so let's take a moment to explain them. You use capability tokens to sign communications from your iOS app to Twilio. In a production application, these tokens are created by you on your server and allow you to specify what capabilities are going to be available to your app, such as whether it can receive incoming connections, make outgoing connections, etc.
For the security of your Twilio account, you should not embed a Capability Token or your Twilio Account's Auth Token in the app you submit to the App Store.
You can read more about capability tokens and their best practices here.
Tokens always have an expiration, which means all tokens have a limited lifetime to protect you from abuse. The token generated here is valid for one hour unless otherwise specified. To specify a different period of time, pass in the number of seconds as the expires
parameter to TwilioCapability.generate()
– for example, for a token that expires after 5 minutes, call TwilioCapability.generate(expires = 300)
. The maximum allowed lifetime for a token is 24 hours.
Now, back to coding! If you compile and run this code, you should see the following:
Now, we've got an app that can create outgoing connections and receive incoming connections.
For the time being, we'll focus on making an outgoing connection. The connection will call a Twilio sample application that responds with a friendly greeting.
Dialing out
Let's add a method to HelloMonkeyViewController
to initiate a connection. To make a connection, we call the TCDevice
's
-connect:(NSDictionary*)params delegate:(id<TCConnectionDelegate>)delegate
method. Just pass in nil
parameters and a nil
delegate for the moment;
we'll do more with these arguments later.
HelloMonkeyViewController.m
- (IBAction)dialButtonPressed:(id)sender { _connection = [_phone connect:nil delegate:nil]; }
Connections to Twilio, either incoming or outgoing, are represented by
instances of the class TCConnection
. In addition, status callbacks are provided to objects that implement the delegate protocols TCDeviceDelegate
and TCConnectionDelegate
.
If you now compile the app and run it, you should be able to click the "Dial" button and hear the greeting. Awesome!
Wouldn't it be nice if you could also hang up on a connection if you don't want to hear the whole thing? Let's go do that now.
Hanging up from your iOS Device
Congratulations on making your first audio connection from your iOS device to Twilio!
You should have heard a welcome message but as you probably noticed, you had no way to close the connection as the Hangup button doesn't do anything. So, let's add some functionality to do that.
Let us just add code in HelloMonkeyViewController
to hangup ongoing connection.
HelloMonkeyViewController.m
- (IBAction)hangupButtonPressed:(id)sender { [_connection disconnect]; }
That's everything! Go ahead and make another call. You can now press the hangup button at any time and your connection will close.
Connecting to a TwiML Application
Wondering what actually happens when you connect using your app, and why you keep hearing that same welcome message? The key to this mystery is in the Python server we deployed earlier. Let's take a look at that code:
server.py
APP_SID = 'YOUR APP SID HERE' # some code ommitted here @app.route('/token') def token(): account_sid = os.environ.get("ACCOUNT_SID", ACCOUNT_SID) auth_token = os.environ.get("AUTH_TOKEN", AUTH_TOKEN) app_sid = os.environ.get("APP_SID", APP_SID) capability = TwilioCapability(account_sid, auth_token) # This allows outgoing connections to TwiML application if request.values.get('allowOutgoing') != 'false': capability.allow_client_outgoing(app_sid) # This allows incoming connections to client (if specified) client = request.values.get('client') if client != None: capability.allow_client_incoming(client) # This returns a token to use with Twilio based on the account and capabilities defined above return capability.generate()
This portion of the code is responsible for creating a capability token that tells your Twilio Device what actions it is allowed to perform.
The two lines below tell your device to make outgoing connections to the App Sid APa4983020a0b29fb5db1b1dc68e322fbe
.
APP_SID = 'APa4983020a0b29fb5db1b1dc68e322fbe' # ... some code omitted here ... capability.allow_client_outgoing(app_sid)
Applications are just references to TwiML URLs that are fetched when a connection is established from a device, a browser, or a phone. If you are not familiar with TwiML, we suggest you head over to Twilio Markup Language Quickstart.
The string starting with 'AP' is an Application SID. You entered this Application Sid when you deployed the server in the steps above. That Application's Voice URL points to your server's /
endpoint, which returns the TwiML to say "Welcome to Twilio".
<?xml version="1.0" encoding="UTF-8"?> <Response> <Say>Welcome to Twilio</Say> </Response>
We change the user's telephony experience by generating different TwiML. Let's continue with an example that let's us dial any phone number.
Passing Parameters to your Application to Make a VoIP Call
Now, let's make a Twilio Application that can actually do something useful by passing data from your iOS app to your TwiML script. Let's dial out to an arbitrary phone number. It'll be easy, all we need to do is:
- Grab a phone number from a text field.
- Pass that phone number along to
TCDevice
's-(void)connect:(NSDictionary*)parameters delegate: (id<TCDeviceDelegate>)delegate
method. - Update your TwiML Application to point to the back-end endpoint that receives this input and dials the number entered by the user.
Let's go do it!
The text field in the app is wired up to the property numberField
in
HelloMonkeyViewController
. We'll now add some code to pass this through
to your script when creating the connection.
In HelloMonkeyViewController.m
, create a NSDictionary*
with an object
containing key To
and value of the text field. Pass this dictionary to the
connect
method.
HelloMonkeyViewController.m
- (IBAction)dialButtonPressed:(id)sender { NSDictionary *params = @{@"To": self.numberField.text}; _connection = [_phone connect:params delegate:nil]; }
Now, let's change our TwiML Application to point to our app's /call
endpoint. Go to the TwiML apps page in the account portal, change your application's Voice URL to point to your server's /call
endpoint: http://{your server url}/call
, and save your changes.
Now, go ahead and compile your app for the iOS Simulator. Run it, enter another phone number in the box and hit dial. Your phone will ring and you can talk to yourself! Huzzah!
Here's how it works. When your application connects to Twilio, your TwiML App's Voice URL points to the /call
endpoint on your python server, which runs the following code:
server.py
@app.route('/call', methods=['GET', 'POST']) def call(): resp = twilio.twiml.Response() from_value = request.values.get('From') to = request.values.get('To') if not (from_value and to): return str(resp.say("Invalid request")) from_client = from_value.startswith('client') caller_id = os.environ.get("CALLER_ID", CALLER_ID) if not from_client: # PSTN -> client resp.dial(callerId=from_value).client(CLIENT) elif to.startswith("client:"): # client -> client resp.dial(callerId=from_value).client(to[7:]) else: # client -> PSTN resp.dial(to, callerId=caller_id) return str(resp)
This code looks at the From
parameter in the request from Twilio. If the connection is coming from your iOS application, it grabs the To
parameter passed by your application and dials the number.
Things work a bit differently if the call is coming from a PSTN phone number. Let's dig into that now: Now, it's time to get your app ringing.
Receiving Incoming Calls
Now, that we know how to initiate connections from your app, it's time for your app to start receiving incoming connections! By the end of this tutorial, you will be able to call in to your device using the iOS Simulator (or vice-versa). Hold on tight…
To receive incoming connections, we'll do the following things:
- Give the app client a name and "register" it with Twilio.
- Add callbacks to notify your app of incoming connections via delegate methods.
Change your code to pass a client name to your application server when
it starts up. (In a real app, you would pass a username/password
combination from UITextField
s, but we'll omit this for simplicity.)
TCDevice
announces important events to an object that implements the
TCDeviceDelegate
protocol:
-(void)deviceDidStartListeningForIncomingConnections:(TCDevice*)device
:
callback for when the device is successfully registered with Twilio.
-(void)device:(TCDevice*)device didStopListeningForIncomingConnections:(NSError*)error
:
callback for when the device is no longer listening for incoming
connections due to error or a call to -[TCDevice unlisten]
.
-(void)device:(TCDevice*)device didReceiveIncomingConnection:(TCConnection*)connection
:
callback for when a client receives an incoming connection
Please register the instance of HelloMonkeyViewController
to be
TCDevice
's delegate during (id)viewDidLoad
:
HelloMonkeyViewController.m
@interface HelloMonkeyViewController() <TCDeviceDelegate> { TCDevice* _phone; TCConnection* _connection; } @end @implementation HelloMonkeyViewController - (void)viewDidLoad { NSURL *url = [NSURL URLWithString:@"http://companyfoo.com/token?client=jenny"]; NSError *error = nil; NSString *token = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error]; if (token == nil) { NSLog(@"Error retrieving token: %@", [error localizedDescription]); } else { _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:self]; } } @end
Next, implement
-(void)device:(TCDevice*)device didReceiveIncomingConnection:(TCConnection*)connection
and have it accept the incoming connection when we get the callback.
Note that we can only accept incoming connection when the device is not busy.
HelloMonkeyViewController.m
- (void)device:(TCDevice *)device didReceiveIncomingConnection:(TCConnection *)connection { if (device.state == TCDeviceStateBusy) { [connection reject]; } else { _connection = [connection accept]; } }
For completeness, implement the remaining two delegate methods to print
out various state transitions and any errors (note that
-device:didStopListeningForIncomingConnections:
is a required method for the
delegate):
HelloMonkeyViewController.m
- (void)deviceDidStartListeningForIncomingConnections:(TCDevice*)device { NSLog(@"Device: %@ deviceDidStartListeningForIncomingConnections", device); } - (void)device:(TCDevice*)device didStopListeningForIncomingConnections:(NSError*)error { NSLog(@"Device: %@ didStopListeningForIncomingConnections: %@", device, error); }
If you compile and run the app, it's now ready to receive incoming
calls! Now we need to
provision a Twilio phone number
and configure the Voice URL to point to your application server: http://{your app's url}/call
.
Call your Twilio number and you should be connected to your device (or iOS Simulator, whichever you're running), which will automatically answer the call! Start talkin'.
Ready to put it all together?
Making Calls in/out of your App
Time to put it all together… you've already initiated an outgoing connection and received an incoming connection. Now, let's call from one client to another!
For this example, we'll make a call between the iOS Simulator and your device.
To do this, we'll need to log in as two different users. We'll change the log in code to register as "tommy" for the app in the iOS Simulator, and "jenny" for the app on your iOS device.
In HelloMonkeyViewController.m
's -(void)viewDidLoad
method, add some
conditional-compilation code:
HelloMonkeyViewController.m
-(void)viewDidLoad { #if TARGET_IPHONE_SIMULATOR NSString *name = @"tommy"; #else NSString *name = @"jenny"; #endif NSString *urlString = [NSString stringWithFormat:@"http://companyfoo.com/token?client=%@", name]; NSURL *url = [NSURL URLWithString:urlString]; NSError *error = nil; NSString *token = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error]; if (token == nil) { NSLog(@"Error retrieving token: %@", [error localizedDescription]); } else { _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:self]; } }
The Python script has some simple call routing rules:
- If the call is coming from PSTN, the app tells to Twilio to dial Client
jenny
. - Otherwise, the application tells Twilio to dial whatever number is passed in the
To
parameter: If theTo
parameter is a PSTN number, it writes that out within the<Number>
noun (which then will call a regular phone). If theTo
parameter is another client name, as indicated byclient:
prefix, it writes out a<Client>
noun, which will try and connect to a named Twilio Client app (a browser or another mobile client).
So now build, install, and run your app on both your iOS device and iOS Simulator. Then have one of the platforms call the other (e.g. by typing "client:tommy" into the iOS device's app). Once the connection has been established you should be able to talk between your phone and your laptop! And of course, you can call regular phone numbers as we demonstrated above.
Wrapping up
That's it for this Quickstart!

Callback
is an event listener registered with the Manager
,
listening for manager or Simon events.
See:
Description
| Interface Summary | |
|---|---|
| Callback | Callback processes various events of the Java Simon API and is used as an extension point of the API. |
| CompositeCallback | Composite Callback can hold more callbacks which allows to form callback trees where events are passed to
sub-callbacks. |
| FilterCallback | FilterCallback extends Callback adding filtering capabilities. |
| Class Summary | |
|---|---|
| CallbackSkeleton | Implements Callback interface so that it does nothing - intended for extension by simple (non-composite)
callbacks. |
| CompositeCallbackImpl | Composite callbacks holds child-callbacks and delegates any operations to all of them. |
| CompositeFilterCallback | This callback combines Composite and Filter behavior. |
| FilterRule | Represents filtering rule that checks whether sub-callbacks will get the event. |
| Enum Summary | |
|---|---|
| Callback.Event | Enumeration of all supported callback actions. |
| FilterRule.Type | Enumeration of rule types that determines the evaluation of multiple rules in a chain. |
Callback
is an event listener registered with the Manager
,
listening for manager or Simon events. Any number of callbacks can be registered on a manager using
Manager.callback()
and CompositeCallback.addCallback(Callback)
.
CallbackSkeleton
can be extended if only selected events are desired to be
implemented instead of implementating the whole Callback
interface.
Composite callbacks are used to organize other callbacks in trees and then to delegate all events to them.
It is not recommended to mix composite callbacks with functionality, generally it should not be necessary to implement
composite callbacks in addition to the following two provided implementations:
CompositeCallbackImpl
delegates all events to all sub-callbacks
(used in EnabledManager
for instance);CompositeFilterCallback
allows to filter events that should be propagated to the sub-callbacks,
filter rules can be added using
FilterCallback.addRule(org.javasimon.callback.FilterRule.Type, String, String, org.javasimon.callback.Callback.Event...)
.
