Solving the iOS Binding Problem with Swift
19 Feb 2015This text was originally published at http://five.agency/solving-the-binding-problem-with-swift/. Check out the original for some nice illustrations!
In a fight for great software architecture, our hands are often tied by the shortcomings of frameworks or languages we work with. Simple tasks like downloading a photo and presenting it in a view, updating a view when underlying data changes, or propagating user input to a model tend to introduce unnecessary complexity to our code.
Problem is that we’re so used to thinking in terms of value assignments that we try to apply same approach to situations that require something different. Assignment is a one-time operation. It’s low-level. It’s good for static values. Assignment is, however, terrible for dynamic data. In order to accommodate prices that change, followers that rise or faces that get prettier we need something of a higher level. We need to think in terms of bindings.
In this post we’ll present a solution that makes binding of dynamic data to user interfaces as simple as it gets, giving you an opportunity to focus on what needs to be done, rather than on how to do it.
Problem analysis
Let’s explore a simple example of dynamic data. Say that we’re developing some kind of a discussion thread feature. We’ll consider a one-thread scenario. Thread will have a name and a list of posts. Each post will be composed of a body and number of likes. In the real world, models would have more properties like user reference or a date, but we’ll ignore those as they are not important for our problem analysis.
class Thread {
var name: String
var posts: [Post]
}
class Post {
var body: String
var likeCount: Int
}
We need a view that will display the thread. Let’s define a view with a name label and a posts table view composed of a post cells.
class ThreadView {
var nameLabel: UILabel
var postsTableView: UITableView
}
class PostCell {
var bodyTextView: UITextView
var likeCountLabel: UILabel
}
What’s left is coupling all that together. Say we’re doing it from a view controller.
class ThreadViewController: UIViewController, UITableViewDataSource {
var thread: Thread
var threadView: ThreadView
override func viewDidLoad() {
super.viewDidLoad()
threadView.nameLabel.text = thread.text
threadView.postsTableView.dataSource = self
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return thread.count()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("PostCell") as PostCell
let post = thread.posts[indexPath.row]
cell.bodyTextView.text = post.body
cell.likeCountLabel.text = "\(post.likeCount)"
return cell
}
}
Simple enough. Sure, but there is problem. Users can write posts. Thread name might be updated. Some of the currently visible posts might even get liked. What will happen to our view? Exactly - nothing. Data from the model is assigned once. Any subsequent change to it will not be reflected in the view. Your likes won’t count. We don’t want that to happen, do we?
OK, but what are our options?
There are a couple of ways to fix that. The simplest and probably dumbest solution would be to expose methods on the view controller that update its state, then give the model the reference to the view controller and have it call exposed methods whenever change occurs. Oh, and also to say goodbye to any future reusability of those components, to simple object graphs, to single responsibility principle and other “unimportant” principles.
A better solution would be to have the model define a protocol that parties interested in observing its changes would implement. In that case, thread view controller would implement the protocol and register itself to the model as an observer (a delegate). This approach makes components more reusable but it’s cumbersome to implement, especially if you have many models. When you think about it, it’s actually same as the first approach, just wrapped up in nice colors.
Another solution might be to use Key-Value-Observing mechanism to observe data changes and update the view accordingly. While this approach keeps architecture simple, it’s quite hard to use and, due to its nature, unsafe in some situations. You need to be vigilant while adding and removing observers. You also need to manually downcast objects, as KVO is not type-safe. Additionally, you can’t do “fine grain” observing of an array, so you’d have to reload whole table regardless of the kind of array update.
Of course, you could do something totally different. For example, you could introduce a Functional reactive paradigm to your architecture with ReactiveCocoa framework and use streams and signals to solve the issue. While it’s a good solution, it introduces a whole new paradigm as well as the complexity you might not need.
What we would like is something as simple as static assignment, but without the burden of additional protocols, complexities or limitations.
A Swift solution
In order to keep the view up to date with the underlying data, we must somehow observe changes in the data and propagate them to the view. There is no way to have some third party observe the changes of a variable, but if you give it some thought, same thing can be achieved by wrapping a variable in an object and updating its value through that object. Now we have a way to intercept changes and notify interested parties of what happened.
In order to do that, we’ll use a neat Swift feature called property observers. Additionally, we’ll use generics to make our wrapper compatible with any type. Let’s call it Dynamic, as it encapsulates dynamic data.
class Dynamic<T> {
var value: T {
didSet {
// Inform interested parties
}
}
init(_ v: T) {
value = v
}
}
That should be straightforward - a class that encapsulates a value of generic type T. Setting of a value is intercepted by didSet property observer. What’s left if to inform interested parties that change occurred, but before we can do that, we need to define what those parties actually are. Time for another round of thinking.
What’s on the other end of our problem? A view. All kinds of views. Sometimes even something other than a view, maybe another model or an action. It makes sense to think of that side of the problem as a task that needs to be done - view updated, model changed or an action performed. Tasks can be defined by a closure, and that’s how we’ll define our task. We’ll call that task closure Listener and define it as follows:
swifttypealias Listener = T -> Void
In other words, Listener is a closure that accepts a value of generic type T and performs some task with received value. It doesn’t return anything.
Next, we need to somehow couple our Dynamic and our Listener, so that a Listener gets called whenever a value of a Dynamic changes. We could have a property on the Dynamic that retains a Listener, but that would not be a good idea because we don’t want tasks to be owned by the data. We want tasks to be alive when they are needed (for example while the view is alive) and we want them out of our way when we don’t need them. For that reason, we’ll wrap them in an object.
We are aiming for a type that can encapsulate a Listener closure and that can be bound to the Dynamic so that data changes can trigger closure calls. Let’s call it Bond as it creates a bond between a Dynamic and a Listener. Here is the definition:
class Bond<T> {
var listener: Listener
init(_ listener: Listener) {
self.listener = listener
}
func bind(dynamic: Dynamic<T>) {
// Bind to given dynamic
}
}
Nothing too hard. To wrap things up, let’s implement actual binding support. For that, we’ll need to extend the Dynamic with an array of Bonds and implement didSet property observer so it iterates over that array and calls wrapped closures.
class Dynamic<T> {
var value: T {
didSet {
for bondBox in bonds {
bondBox.bond?.listener?(value)
}
}
}
var bonds: [BondBox<T>] = []
init(_ v: T) {
value = v
}
}
class BondBox<T> {
weak var bond: Bond<T>?
init(_ b: Bond<T>) { bond = b }
}
Notice how we’ve wrapped array elements in a helper class named BondBox. That’s because we don’t want to strongly reference bonded Bonds. Their life cycle is their own business.
Actual binding is done by appending Bonds to bonds array. We’ll do that in bind method of class Bond.
class Bond<T> {
var listener: Listener
init(_ listener: Listener) {
self.listener = listener
}
func bind(dynamic: Dynamic<T>) {
dynamic.bonds.append(BondBox(self))
}
}
That’s it - we have our binding mechanism. We can use our thread name property as an example. For start, we’ll make it dynamic String instead of just String, like this:
var name: Dynamic<String>
Setting of a value is done through value property:
name.value = "Steve"
How do we bind it to nameLabel? First we create a Bond with a closure that updates the label.
let nameBond = Bond() { [unowned self] name in
self.nameLabel.text = name
}
Then we bind it:
nameBond.bind(name)
Mission accomplished. Whenever a value of name property changes, the text of nameLabel will also change to newly set name.
Brushing it up
Although presented solution solves the problem of complex architecture and is type-safe, it’s still inconvenient to use and potentially unsafe. We have to create Bonds, retain them, write closures and worry about strongly referencing self.
If we think a bit more about it, it becomes obvious that the views themselves should provide Bonds to which we could attach Dynamics. For example, task of updating the label doesn’t change, it’s always: “update the text property to new value”. Doing that manually is bad, but fortunately, Swift allows us to extend existing types with new functionality.
Let’s explore how that would work on a label. We’ll extend it, so it provides another property - a Bond object:
private var handle: UInt8 = 0;
extension UILabel {
var textBond: Bond<String> {
if let b: AnyObject = objc_getAssociatedObject(self, &handle) {
return b as Bond<String>
} else {
let b = Bond<String>() { [unowned self] v in self.text = v }
objc_setAssociatedObject(self, &handle, b, objc_AssociationPolicy(OBJC_ASSOCIATION_RETAIN_NONATOMIC))
return b
}
}
}
Looks somewhat ugly, but it’s actually very simple. As UIKit is an Objective-C framework, we can use associated objects mechanism to associate arbitrary object to a UILabel. In this case, we’re associating a Bond object with a closure that updates label’s text property. We can do similar thing for other types of views like image views, text views, buttons, sliders, etc.
Let’s see how that simplifies our bindings. Instead of creating and retaining a Bond object, writing a closure and dealing with self, we can do this:
nameLabel.textBond.bind(name)
Much easier and safer, but there is still room left for an improvement. We could define a custom operator that replaces that bind method.
infix operator ->> { associativity left precedence 105 }
public func ->> <T>(left: Dynamic<T>, right: Bond<T>) {
right.bind(left)
}
With that, we can bind our data to view like this:
name ->> nameLabel.textBond
It can get even better. Let’s define a common protocol for types that can be “bonded to” like this:
public protocol Bondable {
typealias BondType
var designatedBond: Bond<BondType> { get }
}
It defines the designatedBond property. In case of UILabel, the designated bond would be textBond, in case of an image view it might be imageBond. For example:
extension UILabel: Bondable {
var designatedBond: Bond {
return self.textBond
}
}
Reason we want it defined through protocol is that we want to perform certain actions on objects that adhere to it without caring of what concrete type object really is, which could be UILabel, UIImageView, UISlider or something else. Why? Because of this:
public func ->> <T, U: Bondable where U.BondType == T>(left: Dynamic<T>, right: U) {
left ->> right.designatedBond
}
It overloads the -» operator so it can bind a Dynamic to an object that adheres to Bondable protocol (given that generic types match - you cannot bind an image to a label).
With that, our binding is reduced to something as simple as:
swift
name ->> nameLabel
Awesome.
Handling mismatching types
Let’s consider likeCount property. It’s a number, so we’ll redefine it as follows:
let likeCount: Dynamic<Int>
How do we bind it to a label? If you’re thinking about
likeCount ->> likeCountLabel
you’re mistaken. Problem is that likeCount holds an Int value, but label expects a String value. That line would not even compile, which is a good thing as it means that our solution is type-safe. We need to somehow add support for type transformations. In functional paradigm that’s called mapping. As Swift partially leans toward the function paradigm, let’s see how a map function that operates on a Dynamics would look like.
func map<T, U>(dynamic: Dynamic<T>, f: T -> U) -> Dynamic<U>
For the sake of length of this post, let’s ignore implementation details. You can look it up on GitHub should you be interested. You will find the link at the bottom.
What map does is converts Dynamic of some type T to a Dynamic of some type U. It does that by applying given closure that converts value from type T to type U. With that, we can solve out like count problem.
map(likeCount) { "\($0)" } ->> likeCountLabel
It’s also possible extend Dynamic class with map function and do binding like this:
likeCount.map { "\($0)" } ->> likeCountLabel
With all that, we can now rewrite our initial example with new approach. We need to convert static properties of the model to dynamic ones
class Thread {
let name: Dynamic<String>
let posts: [Post]
}
class Post {
let body: Dynamic<String>
let likeCount: Dynamic<Int>
}
and update the view controller to do binding instead of assignment
class ThreadViewController: UIViewController, UITableViewDataSource {
var thread: Thread
var threadView: ThreadView
override func viewDidLoad() {
super.viewDidLoad()
thread.text ->> threadView.nameLabel.text
threadView.postsTableView.dataSource = self
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return thread.count()
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("PostCell") as PostCell
let post = thread.posts[indexPath.row]
post.body ->> cell.bodyTextView.text
post.likeCount.map { "\($0)" } ->> cell.likeCountLabel.text
return cell
}
}
Looks almost identical to initial version, but with significant difference in that the data is now bonded to user interface and any change to it will be automatically reflected in views.
There is one problem though - it works great for scalar types, but what about arrays? How do we update the table view when new posts arrive?
Arrays are special
When dealing with arrays, we are usually not interested in the change of the array object as whole, rather in changes that occurred within the array itself like insertions, deletions or updates.
Bond object allows us to observe only value changes, and value is in this case an array as whole. In order to observe fine-grain changes, we need a special kind of Bond. For example a Bond defined in following way:
class ArrayBond<T>: Bond<Array<T>> {
var insertListener: (([Int]) -> Void)?
var removeListener: (([Int], [T]) -> Void)?
var updateListener: (([Int]) -> Void)?
}
It would allow us to register different listeners for different events. Each listener is a closure that accepts an array of indices of elements that have been changed in bonded Dynamic. Removal listener also receives elements that are removed.
Our Dynamic doesn’t know when and how to call these new listeners, so we would need a special kind of Dynamic. One with additional methods for array manipulation. We would need something that would work as following example:
let posts = DynamicArray<Post>()
let myBond = ArrayBond<Post>()
myBond.insertListener = { indices in
println("Inserted posts at indices \(indices)")
}
myBond.updateListener = { indices in
println("Updated posts at indices \(indices)")
}
posts ->> myBond
posts.insert(Post(...), atIndex: 0)
// prints: Inserted posts at indices [0]
posts[4] = Post(...)
// prints: Updated posts at indices [4]
What’s interesting with that is that it would allow us to extend a table view with a Bond that acts as its data source. The Bond would accept Dynamics of UITableViewCell type and we could use map function to convert posts to cells, like this:
class Thread {
let name: Dynamic<String>
let posts: DynamicArray<Post>
}
class Post {
let body: Dynamic<String>
let likeCount: Dynamic<Int>
}
class ThreadViewController: UIViewController, UITableViewDataSource {
var thread: Thread
var threadView: ThreadView
override func viewDidLoad() {
super.viewDidLoad()
thread.text ->> threadView.nameLabel.text
thread.posts.map { [unowned self] (post: Post) -> PostCell in
let cell = self.tableView.dequeueReusableCellWithIdentifier("PostCell") as PostCell
post.body ->> cell.bodyTextView.text
post.likeCount.map { "\($0)" } ->> cell.likeCountLabel.text
return cell
} ->> self.tableView
}
}
It would allow us to populate and bind whole screen with few simple binding operators. Going through the implementation details of how it could be achieved is beyond this post, but concepts are very similar to ones presented for scalar values.
Conclusion
Presented solution boils binding problem down to just one operator. It’s simple, powerful, type-safe and multi-paradigm - just like Swift. It allows you to think differently when coupling data with the view and makes the whole process smooth.
You can find implementation of presented concepts on GitHub in a framework named Bond. It includes both implementation of scalar Dynamic and Bond classes, as well as implementation of vector DynamicArray and ArrayBond classes. You can find it at https://github.com/SwiftBond/Bond.


A very common task for software devs is to read and comprehend other people’s code and project specifications. This is not a particularly easy thing to do, and requires a different type of focus than regular pleasure reading.
Jumping into an existing codebase of hundreds of files and potentially millions of lines can be a daunting task, but needn’t be a scary one if you systematically go about understanding the code that you’re responsible for.
What you need is a map that describes all the code and how it interrelates. When you first look at the map, it’s blank except for where you’re standing. But as you explore, you’ll fill in the map. Of course, when you’re doing this, don’t jump around the map randomly; you should explore the area starting from someplace you’ve already explored. (I.e. look at the functions that this function calls and explore them.)
This map might be a physical drawing. Lots of us use whiteboards to do this.
Some pointers:
Be ready to take lots of notes. Have a notebook, whether virtual or real.
Draw diagrams.
Identify the starting point of the program or module that you’re working on.
Figure out which functions and modules call which other functions and modules.
Identify the most important functions. Also identify “helper” functions that are more stand-alone.
Figure out which functions and modules are responsible for what.
Be comfortable not knowing some of the codebase. Learn what you need to learn first; leave the rest for another day.
Specifications are documents that describe in minute detail everything that needs to be programmed in order to implement a system. (Ideally they show this. Practically, there are usually details lacking.) Specifications are the final word on how software is supposed to work. If the results don’t match the spec, it’s a bug.
Although this is written with an eye toward project specifications, it also applies to algorithm descriptions in books, as well as assignments.
These documents tend to be very information-dense. That is, there are no words wasted in a sentence, which means you’ll have to read it at a much slower rate than you might expect. Even now, after reading the previous sentence where you said, “Ok, a lot slower, cool,” you might need to slow it down by yet another order of magnitude again.
For example, here is a sentence from Neil Stephenson’s famous book Snow Crash:
The whole idea of stealing fantastically dangerous weapons presents the would-be perp with inherent dangers and contradictions: When you are wrestling for possession of a sword, the man with the handle always wins.
And here is a sentence from Thomas Cormen’s famous book Introduction to Algorithms:
We define the height of a node in a tree to be the number of edges on the longest simple downward path from the node to a leaf, and we define the height of the tree to be the height of its root.
You might notice that the latter, in additional to being relatively more boring, was much harder to understand. Not only that but the second part of the definition seemingly refers to itself. Most engineers cannot skim this and understand it.
This is a sentence that has to be read very slowly in order to comprehend it. Probably several times. If you find it slow going, it doesn’t mean you’re bad at it. This information is meant to be read and comprehended slowly.
Here are some pointers for getting through this kind of reading:
Read very slowly.
Read even slower than that.
After you finish a couple sentences or a paragraph, quickly summarize them to yourself. Not only does this verify understanding, but also helps cement it.
Make note of things the sentence says that you don’t know. E.g., what does “simple path” mean?
Sometimes you can keep reading past, trusting later context to give it meaning.
Other times, it prevents further understanding and must be clarified on the spot.
If it can wait until later, make note of it and look it up later.
Make a written outline or summary of what you’re reading.
Draw sample diagrams to test your understanding.
Lastly, here is an excerpt from RFC 739, the spec for the Transmission Control Protocol, more commonly known as TCP (of TCP/IP fame):
The checksum field is the 16 bit one’s complement of the one’s complement sum of all 16 bit words in the header and text. If a segment contains an odd number of header and text octets to be checksummed, the last octet is padded on the right with zeros to form a 16 bit word for checksum purposes.
See if you can make sense of that using the techniques, above. It is expected to take a while.

On Sound Localization
Author: Hans Wallach
Date: April, 1939
Experiment 1
Subjects Tested: 17
The goal of the experiment was to produce a syntehtic sound at a given angle while the head rotates (thus eliminating head rotation as a variable in localization). If the sound was heard at the same position relative to the listener than it would indicate head movement played a role in localization.
Twenty loudspeakers were arranged in an arc around the observer. His head was attached to a switch, in which a contact spring slid over a series of contact points when he turned his head. Each of these contact points was connected to one of the loudspeakers so that, while the spring slid over the contact points, the loudspeakers were successively brought into action by the speaker current, which passed the switch without interruption.
Results
...results seem to be convincing. However, the change of lateral angle with respect to a head movement is not the only factor which furnishes information about the position of the sound source in the dimension of the median plane. One can readily discriminate between front and back without a head movement, and for some sorts of sound a crude discrimination of different elevations is possible with resting head...it seems evident that it is effected by the selective sound shadow of the pinnae.
Design Decisions
While such an experiment can be replicated (and possibly performed with greater control) in VR in is important to note the spatializer need to acount for subject head translation, rotation and tilt.

The brewer
scales were carefully designed and tested on discrete data.
They were not designed to be extended to continuous data, but results often
look good. Your mileage may vary.
The following palettes are available for use with these scales:
BrBG, PiYG, PRGn, PuOr, RdBu, RdGy, RdYlBu, RdYlGn, Spectral
Accent, Dark2, Paired, Pastel1, Pastel2, Set1, Set2, Set3
Blues, BuGn, BuPu, GnBu, Greens, Greys, Oranges, OrRd, PuBu, PuBuGn, PuRd, Purples, RdPu, Reds, YlGn, YlGnBu, YlOrBr, YlOrRd
Modify the palette through the palette
arguement.
The distiller
scales extend brewer to continuous scales by smoothly
interpolating 7 colours from any palette to a continuous scale. The fermenter
scales provide binned versions of the brewer scales.
Other colour scales:

The term Thrissur is the abbreviated anglicized form of the Malayalam word ‘THRISSIVAPERUR’ which means the town of the “SACRED SIVA”. The town is built on an elevated ground, at the apex of which is the famous “VADAKKUMNATHAN” Temple. A place of great antiquity, Thrissur was also known as “VRISHABHADRIPURAM” and “TEN KAILASAM” in ancient days.The architectural design of the city also worths special mentioning as it was envisioned by Sakthan Thampuran, the ruler of erstwhile Cochin state. City located around a small hillock mounted by the Vadakkumnathan temple can be seen scientifically planned. Actually the city is built around the vast open space called ‘Thekkinkadu maidanam’ surrounding the centrally located Vadakkumnatha temple.Around the maidan lies the ‘Swaraj Round’, the circular ring road, with several radial roads starting from it. The raised centre and the slopes starting from there are surrounded by green, fertile wetlands used for cultivating paddy.


| Tags | GitHub, Version Control |
So this is my first week of phase 0 and so far it has been a blast. The challenges have been “challenging” to say the least and has taken much of my brain power to figure out. There are many coding commands and steps taken through them that I have to memorize. And being the programming noob that I am, I had to go back numerous times to get my work in order. So in this blog I am writing about version control and git through my own understanding of what they are.
Git keeps a “git log” of all the changes that you have made so that you can easily go through them and see various modifications, creations, or deletions, that were made. Github is widely used and is a great way to store and share code with others. Storing code on github can lead to self improvement when others offer constructive criticism of your code.


Future Developments.. For Discussion¶
Customising Templates¶
Although we can override a widgets html by including an identically named widget in a projects local template directory (for any templating language that provides template lookup facilites), we need a way of making template customisation able to be used in an ad-hoc way (i.e. not replacing ALL textarea elements).
At the moment the template for a widget is defined by a widgets _template attribute. The first way of overriding templates would be to provide a way of substituting this value. Simply adding an id keyword argument would allow this. Using this you would be able to do the following.
During form creation¶
>>> schema = schemaish.Structure()
>>> schema.add( 'firstName', schemaish.String())
>>> schema.add( 'surname', schemaish.String())
>>> form = formish.Form()
>>> form['firstName'].widget=TextArea()
>>> form['firstName'].widget.id = 'TextAreaCustom'
This first example would look inside the formish/widgets/TextAreaCustom for its template parts.
>>> schema = schemaish.Structure()
>>> schema.add( 'firstName', schemaish.String())
>>> schema.add( 'surname', schemaish.String())
>>> form = formish.Form()
>>> form['firstName'].widget=TextArea(id='TextAreaCustom')
Because both of these override the folder for the widget, any of the field parts can also be overriden. So if you include field_label.html in your folder then just this part will be override
Note
If a template is overridden but the directory only contains a field_label.html (for instance) should the widget default back to using the standard location?
At rendering time..¶
<%
temporary_template = """

% if field.widget._template != 'Hidden':
${field.title}
%endif

<input id="${field.cssname}" type="text" name="${field.name}" value="${field.value[0]}" />

% if field.error:
${unicode(field.error)}
% endif
% if str(field.description) != '':
${field.description}
% endif

"""
${form.header()|n}
${form.metadata()|n}
${form['firstName'](template=temporary_template)|n}

${form['surname'].description}
${form['surname'].error}
${form['surname'].widget()|n}

${form.actions()|n}
${form.footer()|n}
Obviously a big widget like this is silly inline so you could/should/may/might..
temporary_template.html

% if field.widget._template != 'Hidden':
${field.title}
%endif

<input id="${field.cssname}" type="text" name="${field.name}" value="${field.value[0]}" />

% if field.error:
${unicode(field.error)}
% endif
% if str(field.description) != '':
${field.description}
% endif

${form.header()|n}
${form.metadata()|n}
${form['firstName'](template=open('temporary_template.html').read())|n}

${form['surname'].description}
${form['surname'].error}
${form['surname'].widget()|n}

${form.actions()|n}
${form.footer()|n}
Depending on your templating language you may be able to get that string into the call in a better way.
Filtering Field Emission¶
It would be nice to be able to emit a bunch of fields by passing their ids to the fields() callable
${form.header()|n}
${form.metadata()|n}
${form.fields( ['title','firstname'] )|n}

${form['surname'].description}
${form['surname'].error}
${form['surname'].widget()|n}

${form.fields( ['surname','comments'] )
${form.actions()|n}
${form.footer()|n}
If we have a bunch of form fields we want to render with one custom one in the middle, we may want to spit out a slice of the fields.. e.g. fields[:4], then our custom one, then fields[5:]. If we can pass form.fields.keys to form.fields callable, we get lots of stuff for free.. We can apply filters, reductions, slices, etc, etc..
alternate syntaxes¶
personally I think using form.fields is OK.. Obviously the fields iterable is on one level though so we need a walk version of some sort.. Being as we are using dotted dicts omething like .dottedkeys which could then be reduced using different functions..
e.g.
form.fields( form.fields.dottedkeys[1:4] )
form.fields( form.fields.keys[-1] )
This would be a lot nicer as slices on key names soo...
form.fields( form.fields.keys[:'address'] )
form.fields( form.fields.keys['title':'address.country'] )
But we have a problem in that we may want to have ‘inclusive’ slices?? I suppose you could just
I think adding the simple ‘pass in a bunch of keys’ version is OK for most of what we’d like I’m sure..
Further possible example syntax¶
Given this form (just listing a structure for now)
personal_details:
title:
firstName:
surname:
age:
sex:
fancywidget:
address:
street1:
street2:
city:
county:
postcode:
country:
continent:
survey:
question1:
question2:
question3:
question4:
question5:
spam_me_please:
terms_and_conditions:
The folllowing should render the whole form (i.e. they are all equivalent)
form()
# or
form.header()
form.metadata()
form.fields( form.fields.keys )
form.actions()
form.footer()
we’ll skip the header and footer for concisity (great word!)
form.fields( form.fields.keys )
# or
form.fields['personal_details']()
form.fields['address']()
form.fields['survey']()
# or
form.fields['personal_details']()
address = form['address']
address.header()
address.fields[:'county']() # or address.fields( address.fields.keys[:'county'] )
address.fields['county']()
address.fields['postcode':]()
address.footer()
form.fields['survey']()
The reason to split something up like this is to allow a single field to be tweaked.. e.g. the county field may want some custom html?
It’s nice to be able to treat each sub template bit as it’s own virtual form (from a templating point of view) but that all rendered id’s and classes are correct.
Matt was suggesting using some form of ‘select’ method on the form or fields.. e.g.
form.fields['personal_details']()
address = form['address']
address.header()
address.fields.select(':-county')()
address.fields.select('county')()
address.fields.select('-county:')()
address.footer()
form.fields['survey']()
This works as a slice operator but allowing us to be clever and use ‘-‘ as an inclusive or exclusive operator.. hence the following would be equivalent
form.fields['personal_details']()
address = form['address']
address.header()
address.fields.select(':+city')()
address.fields.select('county')()
address.fields.select('+postcode:')()
address.footer()
form.fields['survey']()
I’m not sure whether the inclusive/exclusive operator should go at the front or back ...
Having our own syntax at least allows us to do things like
form.fields['personal_details']()
address = form['address']
address.header()
address.fields.select('street1,street2,street3,city')()
address.fields.select('county')()
address.fields.select('postcode,country,continent')()
address.footer()
form.fields['survey']()
# and
address.fields.select('*,city')()
address.fields.select('county')()
address.fields.select('postcode,*')()
Deriving CSS class names from schemaish types and formish widgets¶
We need a consistent way of naming classes applied to elements when types of subclassed. The following show some possible examples?
Schemaish Types¶
| Declaration | class output |
|---|---|
| ‘name’: Structure(...) | class=”structure” |
|
class=”structure name” |
| ‘todo’: Sequence(String()) | class=”sequence sequence-string” |
| ‘people’: Sequence(Structure()) | class=”sequence sequence-structure” |
| ‘people’: Sequence(Person()) | class=”sequence sequence-structure sequence-person” |
Formish Widgets¶
| Declaration | class output |
|---|---|
| .widget = TextArea() | class=”textarea” |
|
|
| .widget = RichTextArea() | class=”textarea” |
|
|
| .widget = RichTextArea() | class=”textarea richtextarea” |
|
|
| .widget = RichTextArea(type=’special’) | class=”textarea richtextarea special” |

This example shows basic usage of the YUI Test standalone for testing browser-based JavaScript code. Two different TestCase
objects are created and added to a TestSuite
object. The TestRunner
is then used to run the tests once the page has loaded. The YUI 3 Console
is used to output the results of the tests.
The first step is to create a new YUITest.TestCase
object called dataTestCase
.
To do so, using the YUITest.TestCase
constructor and pass in an object literal containing information about the tests to be run:
var dataTestCase = new YUITest.TestCase({
//name of the test case - if not provided, one is auto-generated
name : "Data Tests",
//---------------------------------------------------------------------
// setUp and tearDown methods - optional
//---------------------------------------------------------------------
/*
* Sets up data that is needed by each test.
*/
setUp : function () {
this.data = {
name: "test",
year: 2007,
beta: true
};
},
/*
* Cleans up everything that was created by setUp().
*/
tearDown : function () {
delete this.data;
},
//---------------------------------------------------------------------
// Test methods - names must begin with "test"
//---------------------------------------------------------------------
testName : function () {
var Assert = YUITest.Assert;
Assert.isObject(this.data);
Assert.isString(this.data.name);
Assert.areEqual("test", this.data.name);
},
testYear : function () {
var Assert = YUITest.Assert;
Assert.isObject(this.data);
Assert.isNumber(this.data.year);
Assert.areEqual(2007, this.data.year);
},
testBeta : function () {
var Assert = YUITest.Assert;
Assert.isObject(this.data);
Assert.isBoolean(this.data.beta);
Assert.isTrue(this.data.beta);
},
//---------------------------------------------------------------------
// Test methods - also, may just have a space in the name
//---------------------------------------------------------------------
"This test should fail": function(){
var Assert = YUITest.Assert;
Assert.fail("This test was supposed to fail.");
}
});
The object literal passed into the constructor contains a number of different sections. The first section contains the name
property,
which is used to determine which YUITest.TestCase
is being executed. A name is necessary, so one is generated if it isn't specified.
Next, the setUp()
and tearDown()
methods are included. The setUp()
method is used in a YUITest.TestCase
to set up data that may be needed for tests to be completed. This method is called immediately before each test is executed. For this example,
setUp()
creates a data object. The tearDown()
is responsible for undoing what was done in setUp()
. It is
run immediately after each test is run and, in this case, deletes the data object that was created by setUp
. These methods are optional.
The last section contains the actual tests to be run. Test method names must always begin with the word "test" (all lowercase) in order to differentiate them from other methods that may be added to the object.
The first test in this object is testName()
, which runs
various assertions on data.name
. Inside of this method, a shortcut to YUITest.Assert
is set up and used to run three
assertions: isObject()
on data
, isString()
on data.name
and areEqual()
to compare
data.name
to the expected value, "test". These assertions are arranged in order from least-specific to most-specific,
which is the recommended way to arrange your assertions. Basically, the third assertion is useless to run unless the second has passes and the second
can't possibly pass unless the first passed. Both isObject()
and isString()
accept a single argument, which is the value
to test (you could optionally include a failure message as a second argument, though this is not required). The areEqual()
method
expects two arguments, the first being the expected value ("test") and the second being the actual value (data.name
).
The second and third tests follow the same pattern as the first with the exception that they work with different data types. The testYear()
method works with data.year
, which is a number and so runs tests specifically for numbers (areEqual()
can be used with
all data types). The testBeta()
method works with data.beta
, which is a Boolean, and so it uses the isTrue()
assertion instead of areEqual()
(though it could also use areEqual(true, this.data.beta)
). The last test uses a friendly name, which is just a method name with a space in it, and is set to fail. This is done to show the treatment and data available when a test fails.
Although it's possible that you'll have only one YUITest.TestCase
object, typically there is more than one, and so this example includes
a second YUITest.TestCase
. This one tests some of the built-in functions of the Array
object:
var arrayTestCase = new YUITest.TestCase({
//name of the test case - if not provided, one is auto-generated
name : "Array Tests",
//---------------------------------------------------------------------
// setUp and tearDown methods - optional
//---------------------------------------------------------------------
/*
* Sets up data that is needed by each test.
*/
setUp : function () {
this.data = [0,1,2,3,4]
},
/*
* Cleans up everything that was created by setUp().
*/
tearDown : function () {
delete this.data;
},
//---------------------------------------------------------------------
// Test methods - names must begin with "test"
//---------------------------------------------------------------------
testPop : function () {
var Assert = YUITest.Assert;
var value = this.data.pop();
Assert.areEqual(4, this.data.length);
Assert.areEqual(4, value);
},
testPush : function () {
var Assert = YUITest.Assert;
this.data.push(5);
Assert.areEqual(6, this.data.length);
Assert.areEqual(5, this.data[5]);
},
testSplice : function () {
var Assert = YUITest.Assert;
this.data.splice(2, 1, 6, 7);
Assert.areEqual(6, this.data.length);
Assert.areEqual(6, this.data[2]);
Assert.areEqual(7, this.data[3]);
}
});
As with the first YUITest.TestCase
, this one is split up into three sections: the name, the setUp()
and tearDown()
methods, and the test methods. The setUp()
method in this YUITest.TestCase
creates an array of data to be used by the various
tests while the tearDown()
method destroys the array. The test methods are very simple, testing the pop()
, push()
,
and splice()
methods. Each test method uses areEqual()
exclusively, to show the different ways that it can be used.
The testPop()
method calls pop()
on the array of values, then verifies that the length of the array has changed and
that the value popped off is 4; the testPush()
pushes a new value (5) onto the array and then verifies that the length of the array has
changed and that the value is included in the correct location; the testSplice()
method tests splice()
by removing one
value that's already in the array and inserting two in its place.
To better organize the two YUITest.TestCase
objects, a YUITest.TestSuite
is created and those two YUITest.TestCase
objects are
added to it:
var suite = new YUITest.TestSuite("Example Suite");
suite.add(dataTestCase);
suite.add(arrayTestCase);
The first line creates a new YUITest.TestSuite
object using its constructor, which accepts a single argument - the name of the suite. As with
the name of a YUITest.TestCase
, the YUITest.TestSuite
name is used to determine where execution is when tests are being executed. Although
not required (one is generated if it's not provided), it is recommended that you select a meaningful name to aid in debugging.
Any number of YUITest.TestCase
and YUITest.TestSuite
objects can be added to a YUITest.TestSuite
by using the add()
method. In this example, the two YUITest.TestCase
objects created earlier are added to the YUITest.TestSuite
.
Since the standalone YUI Test library isn't a graphical library, you'll need to use something to visualize the results. This example uses a YUI 3 Console
object. To output the appropriate information into the console, a function is created to handle TestRunner
events:
//function to handle events generated by the testrunner
var TestRunner = YUITest.TestRunner;
function logEvent(event){
//data variables
var message = "",
messageType = "";
switch(event.type){
case TestRunner.BEGIN_EVENT:
message = "Testing began at " + (new Date()).toString() + ".";
messageType = "info";
break;
case TestRunner.COMPLETE_EVENT:
message = Y.substitute("Testing completed at " +
(new Date()).toString() + ".\n" +
"Passed:{passed} Failed:{failed} " +
"Total:{total} ({ignored} ignored)",
event.results);
messageType = "info";
break;
case TestRunner.TEST_FAIL_EVENT:
message = event.testName + ": failed.\n" + event.error.getMessage();
messageType = "fail";
break;
case TestRunner.TEST_IGNORE_EVENT:
message = event.testName + ": ignored.";
messageType = "ignore";
break;
case TestRunner.TEST_PASS_EVENT:
message = event.testName + ": passed.";
messageType = "pass";
break;
case TestRunner.TEST_SUITE_BEGIN_EVENT:
message = "Test suite \"" + event.testSuite.name + "\" started.";
messageType = "info";
break;
case TestRunner.TEST_SUITE_COMPLETE_EVENT:
message = Y.substitute("Test suite \"" +
event.testSuite.name + "\" completed" + ".\n" +
"Passed:{passed} Failed:{failed} " +
"Total:{total} ({ignored} ignored)",
event.results);
messageType = "info";
break;
case TestRunner.TEST_CASE_BEGIN_EVENT:
message = "Test case \"" + event.testCase.name + "\" started.";
messageType = "info";
break;
case TestRunner.TEST_CASE_COMPLETE_EVENT:
message = Y.substitute("Test case \"" +
event.testCase.name + "\" completed.\n" +
"Passed:{passed} Failed:{failed} " +
"Total:{total} ({ignored} ignored)",
event.results);
messageType = "info";
break;
default:
message = "Unexpected event " + event.type;
message = "info";
}
//only log if required
Y.log(message, messageType, "TestRunner");
}
//listen for events to publish to the logger
TestRunner.attach(TestRunner.BEGIN_EVENT, logEvent);
TestRunner.attach(TestRunner.COMPLETE_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_CASE_BEGIN_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_CASE_COMPLETE_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_SUITE_BEGIN_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_SUITE_COMPLETE_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_PASS_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_FAIL_EVENT, logEvent);
TestRunner.attach(TestRunner.TEST_IGNORE_EVENT, logEvent);
The logEvent()
function is used to handle all events. Based on the event, the message and the message type are determined and then a message is logged. This event handler is assigned to the TestRunner
events by using the attach()
method.
With all of the tests defined, the last step is to run them. This initialization is assigned to take place when all of the YUI components have been loaded:
//create the console
var r = new Y.Console({
verbose : true,
newestOnTop : false
});
r.render('#testLogger');
TestRunner.add(suite);
//run the tests
TestRunner.run();
Before running the tests, it's necessary to create a Y.Console
object to display the results (otherwise the tests would run
but you wouldn't see the results). After that, the YUITest.TestRunner
is loaded with the YUITest.TestSuite
object by calling
add()
(any number of YUITest.TestCase
and YUITest.TestSuite
objects can be added to a YUITest.TestRunner
,
this example only adds one for simplicity). The very last step is to call run()
, which begins executing the tests in its
queue and displays the results in the Y.Console
.

Naming
id
's and classes
should all be namespace'd with the prefix ds-
, or whatever relevant prefix depending on the styles being used. We can use interpolation in Sass to easily achieve this.
Example:
Rules
Avoid element selectors
Use child or descendant selectors with element selectors if the element selectors will and can be predictable. Using .module span
is great if a span will predictably be used and styled the same way every time while within that module.
However, as a project grows in complexity, the more likely that you will need to expand a component’s functionality and the more limited you will be in having used such a generic element within your rule.
Do not use id
's for styling
IDs may be used as fragment identifiers, and for JavaScript’s getElementById etc. They should never be used to style an element.
Sass Inception Rule
Sass nesting should never be more than 3 levels deep. If you can limit it to 1 level deep, even better! We want highly performant CSS.
Be cautious using @extend
There are multiple reasons not to use @extend. However it can be used without making a mess with the help of Sass's %placeholder selectors. Only use the @extend directive to extend placeholders, not other selectors.

Write code to be readable and understandable, not to save bytes. Code is written and maintained by people. Ensure your code is descriptive, well commented, and approachable by others. Great code comments convey context or purpose. Do not simply reiterate a component or class name.
Be sure to write in complete sentences for larger comments and succinct phrases for general notes.
Javascript hooks
Classes used specifically for JS hooks should be given the prefix "js-
". This ensures that we maintain a distinction between content and functionality. These classes should never be used for style.
Variable names
Generic, modular names for variables should be used.
If specificity is needed, variables should still be Generic > Specific in their naming convention.
This not only helps in recollection, but will allow a text editor (such as Sublime Text, Coda etc.) to easily suggest colors. This way you don't have to memorize exactly how you named your variables. Rather, you can start generically and get more specific as the text editor auto-suggests variable names.

Udine can be reached by car easily throuh the A23 Highway. If you're coming from Trieste or Venice, your best option is the Udine South exit, whereas Udine North is your best pick if you're coming from Austria or Slovenia. Once you leave the highway, the best way to reach the venue can be seen on google maps.
Udine's train station happens to be at a crossing point between the Venezia-Udine and Trieste-Udine railway lines. It's therefore easy to reach it by train. Once at the train station, there are taxi cabs you can hire, and you also have many public transportation options (IE bus lines 2, 5, 6 and 11).
You can reach Udine by air, through the Venezia, Treviso and Trieste airports. Once you get to Venice or Treviso, your best option to get to Udine is by train. From Trieste you can either hire a taxi or take a bus. For more informations, please refer to the airport websites.
The Cinema Visionario can easily be reached by bus, through lines 2, 5, 6, 11. Buses run approximately every 15-20 minutes and you can get out at the Via Asilo Marco Volpe 43 bus stop. You can ask the driver to notify you once at destination, but you can't purchase tickets from her. Hence it's wise to get your tickets in advance (either at the train station or at newspaper kiosks) before you board buses.

Testing Step #1: Add Extension to Dashboard
With the Product dashboard selected in Tableau, click and drag on the new “Extension” object and choose where on the dashboard you want to add the extension. Alternatively, double-click the “Extension” object and Tableau will automatically add it to your dashboard.
Tableau will prompt you to choose what extension you want to use. Navigate to where you saved “XpWriteBack.trex and select it.
Testing Step #2: Configure Extension
Next, you will be automatically prompted to configure the extension. If you don’t see the above screen, click on the downward facing triangle that can be found in the corner of the extension dashboard zone:
Then select “Configure”. This should get the first screen above to appear.
There are four things to configure:
- “Select the worksheet” – Select the worksheet that you will use to extract data from;
- “Extract all worksheet data” – If this option is selected, all the data is extracted from the worksheet. Otherwise only the data when the mark is selected;
- “Endpoint URL” – The endpoint where to send the data, if you configured the Google Spreadsheet, you add the https://scripts.google.com/... in here.
- “Select the Spreadsheet” – This is optional, if using Google Spreadsheet, you can specify the sheet name where the data will be stored. By default, it is stored in a sheet called Tableau;
- “Add Column” – This is optional; you can add new columns to see in your data;
After adding values to point one and two, the “Submit” button should be enabled and you can click it to start using the extension;
Testing Step #3: Add records to the extension
Select data in worksheet and you should see it in the extension in table format.
Testing Step #4: Create new records
On the top right corner, you should see four buttons.
The first button with a “plus” allows you to create new records and a them to the table.
Click on the button, and you should be prompted with a window with the same fields as in the table. Add values to those fields and click “Submit” to see the data in the table.
Testing Step #5: Add new columns
Open the “Configure” menu like explained above and add columns in there. When finished, click the “Submit” button to see your new columns in the table.
Testing Step #6: Edit records
Select any of the records in the table by clicking over it. If one or more records are selected, you should see in the top right corner, five buttons instead of four.
The second button allows you to edit the record selected.
Click the button and you will be prompted with a new window to edit your record.
When you finish editing what you want, click the “Submit” and your changes should be reflected in the table.
Testing Step #7: Remove record
You can also remove a record by using the button highlighted
If no records are selected all the records in the table will be removed. Otherwise only the selected record is removed.
Testing Step #8: Write Back the Data
By using the highlighted button, you can send the data to the endpoint you defined. After that just check in the spreadsheet and you should be able to see the data you sent.
Testing Step #9: Write back only selected records
Go to the configuration menu.
In the "DataTable" options select the option "Send only selected rows".
When sending the data, only the selected records will be sent.
Testing Step #10: View Measures
Go to the configuration menu.
In the "DataTable" options select the option "Display Measures".
The measures in the worksheet will be displayed in the extension table
Testing Step #11: Default Values
In the Configuration menu, when you add new columns, you can set a default value for them
This allows the new columns to have default values, instead of needing to insert them one by one
It also allows the user to use column already available in the table to create new values
Example:
You can see two measures. SUM(Lucro) and SUM(Vendas) this is SUM(Profit) and SUM(Sales), respectively.
In the cofiguration menu you can add a new column using the values of this column, for that just use the column name between parentheses.
This will make the new column have a calculated value:
This calculations are made using the extension, so do not try to use Tableau formulas.
Testing Step #12: Write-back fields
Go to the configuration menu.
In the "DataTable" options go to "Write-back fields".
The fields checked in where will be sent to the endpoint defined, when writing back data. The unchecked fields, will be ignored.
Testing Step #13: Refresh Datasources
Open the sidebar menu
In the "Datasource Refresh" check the option:
- Refresh on Data Sent to have the worksheet data sources refreshed every time you send data
- Auto Refresh every x seconds to have the worksheet data sources refreshed every x seconds

Ryan Reynolds Crashed Will Ferrell's 'Saturday Night Live' Monologue
by Kayleigh Roberts- Last night, Will Ferrell hosted Saturday Night Live for the fifth time in his career.
- In spite of his ample experience on the SNL stage, both as a five-time host and as a former cast member, Ferrell was thrown off his game by Ryan Reynolds, who made a surprise appearance in the audience at the taping, leaving the comedian starstruck.
- Another former SNL cast member, Tracy Morgan, eventually had to step in to save the day and restore Ferrell's confidence so he could finish his monologue.
Last night was a big milestone for Will Ferrell. The comedian officially joined the ultra-exclusive Saturday Night Live Five-Timers Club (as in the people who have hosted the show at least five times). It will also forever be known as "The Night Ryan Reynolds Threw Will Ferrell Completely Off His Game."
Reynolds crashed the taping of the show and his mere presence in the audience was enough to dominate Ferrell's opening monologue as the host fought his starstruck awkwardness to deliver his speech.
Ferrell began his monologue by having the audience join him in celebrating his Fiver-Timers Club membership and gushing about how much his time as a member of the SNL cast meant to him. Then, well, Ryan Reynolds happened.
"I’m sorry, one second, excuse me, but you look a lot like Ryan Reynolds," he said to an audience member, who was, of course, actually Ryan Reynolds.
“Yeah, I get that a lot," the actor replied.
From there, Ferrell devolved into fanboy status (which we cannot blame him for at all):
Ferrell: "Is it you?"
Reynolds: "Yes, it’s me."
Ferrell: "Oh, oh wow OK, cool, welcome to the show."

Ferrell: "A big fan of me? Oh, OK. Fine.
Ferrell then asked the most obvious question—if Reynolds' wife, Blake Lively, was also a fan.
"And she likes me too?" Ferrell asked.
"Probably more than me," Reynolds replied, prompting a bout of nervous laughter from the host.
Ferrell was unable to focus on his monologue with Reynolds in the audience and eventually another former SNL cast member, Tracy Morgan, had to step in to save the day.
"Ryan Reynolds, you listen to me!" Morgan said. "The prophecy must be fulfilled! This is Will Ferrell! I suckled from his comedy bosom, and like a young Luke Skywalker, it filled me with strength!"
Ferrell did eventually finish his monologue and Reynolds stuck around for the show, even putting in an appearance on Weekend Update, alongside Colin Jost, who got engaged to Reynolds' ex-wife, Scarlett Johansson, earlier this year.

Module spawnusher
Spawn usher is a system that allows to correct the spawn position of players without knowing anything about the mapgen.
The system will register callbacks for newplayer and respawnplayer and will try to find an air bubble, either upwards or downwards, which the player can fit into. If an air bubble is found, the player will be moved there. If the block is not loaded, it will be tried again after a certain amount of time.
The only function that should be called from clients is activate.
Functions
| activate () | Activates the spawn usher system, if it has not been deactivated by a seeting in the configuration. |
| activate_internal () | Activates the system, without checking the configuration. |
| is_air_bubble (start_pos) | Tests if the given position is an air bubble big enough. |
| move_later (player, current_pos) | Schedules the player to be moved later. |
| move_random (player) | Moves the player randomly on the x and z plane. |
| move_player (player) | Moves the player to a safe location. |
| move_players () | Move all players that could not be placed so far. |
| on_spawn_player (player) | Callback for if a player spawns. |
| register_after_spawn_callback (callback) | Allows to register callbacks after a player has been spawned by spawn usher. |
| register_spawnpoint_provider (provider) | Allows to register providers that are called after the final position of the player has been determined. |
Tables
| physics_override | The physics override that is set to make the player inmovable. |
| player_physics | The original physics of the payers. |
Fields
| activate_automatically | If the system should be activated automatically. |
| active | If the system is active/has been activated. |
| after_spawn_callbacks | The list of callbacks that are invoked after the player has been placed. |
| players | The list of players that need to be placed. |
| random_direction | If the player should be facing a random direction after spawning. |
| random_placement_radius | The placement radius around the spawn. |
| required_bubble_size | The required air bubble size. |
| retry_time | The retry time. |
| scheduled | If the system is currently scheduled for execution. |
| spawnpoint | The spawnpoint that is configured. |
| spawnpoint_providers | The registered spawnpoint providers. |
Functions
- activate ()
- Activates the spawn usher system, if it has not been deactivated by a seeting in the configuration.
- activate_internal ()
- Activates the system, without checking the configuration. Multiple invokations have no effect.
- is_air_bubble (start_pos)
-
Tests if the given position is an air bubble big enough.
Parameters:
- start_pos The position at which to check.
Returns:
-
true if at the given position is an air bubble big enough.
- move_later (player, current_pos)
-
Schedules the player to be moved later. Also moves the player to the given
position.
Parameters:
- player The player object.
- current_pos The current position to which the player will be moved.
- move_random (player)
-
Moves the player randomly on the x and z plane.
Parameters:
- player The Player object to move.
- move_player (player)
-
Moves the player to a safe location.
Parameters:
- player The player object.
- move_players ()
- Move all players that could not be placed so far.
- on_spawn_player (player)
-
Callback for if a player spawns.
Parameters:
- player The Player that spawned.
Returns:
-
true, to disable default placement.
- register_after_spawn_callback (callback)
-
Allows to register callbacks after a player has been spawned by spawn usher.
Parameters:
- callback The callback to invoke, a function that accepts the player object as first parameter and the spawn point as second.
- register_spawnpoint_provider (provider)
-
Allows to register providers that are called after the final position of
the player has been determined. The provider can return a different position,
or nil if it is happy with the given position, and if it is is the exact
position or not.
Parameters:
- provider The provider. A function that accepts two parameters, the Player object and the spawn position that the system calculated. It can return a new position, a table with x y z values, or nil if the position should not be changed. The second return value can be true to make the system use the provided position without looking for an air bubble.

This shōdan, the highlight of the Shite Exits dan, raises its Intermedia Index substantially. It marks a return to poetic text set in hiranori accompanied by the percussion instruments in strict rhythmic setting. It also includes a short but lively dance.
The ageuta opens with the very dynamic kakegoe ‘iya,’ which establishes an energetic tone. Set in a fast tempo, the chant’s eight honji are all sung in the rhythmic tsuzuke-utai style. The performed kata are all formal but the text and context provide them with meaning. As we hear the jiutai speaking for the boy-"I will come without fail, at the appointed time" the boy stands up, and facing Munechika, performs a Forward Pointing followed by an Open-retreat, two standard kata that visually . The swordsmith replies by bowing ceremoniously.
Then, as the jiutai mentions the clouds of Mount Inari where the boy is about to vanish, . In preparation for his imminent departure into the sky, the boy builds tension by moving to the very dynamic Square 3, where he circles and faces the waki. Then he releases the tension by going to Square 1 where he performs a Circlet Point. This symbolizes his disappearance, witnessed by Munechika who turns right, rises on his knee, and points to the distance where the young boy has disappeared.

PICS: Prasa blames 'criminals' for being behind vandalism at Park Station
by Ntwaagae SelekaPark Station in Johannesburg was attacked on Tuesday afternoon when groups of people stormed it and damaged property.
According to Passenger Rail Agency of South Africa (Prasa) spokesperson Nana Zenani, the incident took place at around lunchtime.
Zenani blamed criminals for being behind the attack.
She said a group of people had targeted specific areas.
Shops, cars, ticket booth windows, access gates and a train were damaged during the attack.
Zenani said she could not connect the attacks at the station with the recent decision by Prasa to terminate the contracts of 20 private security companies.
She added the rail agency had a good relationship with labour unions, saying she does not want to blame their members without any evidence.
"According to security personnel stationed at Park Station, a number of criminals forcibly entered the station attacking and looting some of the shops, breaking glass access gates, ticket booth windows and cars. More alarming, however, was the stoning of one of the train sets resulting in a broken windows
"Fortunately, no one was injured at the time and we are thankful for that. Our security guards were on duty when the criminals entered the premises. It was a surprise attack and I can't say that our guards were overpowered. There was no confrontation between our guards and the group of criminals," said Zenani.
She added the station had been secured and police officers were on the scene combing the area, and viewing CCTV footages to identify the attackers.
Zenani said the situation was calm and trains were running on schedule.
She has appealed to commuters to continue using the trains.
Zenani asked people with information about the attack to contact the police as soon as possible.
Prasa group CEO Dr Nkosinathi Sishi said: "Prasa will increase security at the station along with a police presence. It will not allow itself to be harassed by criminals. We have the necessary security personnel to ensure such an incident does not repeat itself."
