This reverts commit 6926236268.
There seems to be some bug or timing issue that prevents the
attachedCallback from being called in all cases when the
attributeChangedCallback is defined. We can figure this out at
a later time.
It’s not something that will make sense once we add the ability to have
multiple directories in a project. This adds a new private method on
Project, ::resolvePath, with the original implementation for convenience
until we actually implement multi-folder projects.
It doesn’t make sense to talk about pixels at the model layer long-term,
even though we currently store view dimension information in the model
so we don’t have to read from the DOM for optimization purposes. This
information is only available if the view is attached, however, making
these methods a liability on the model layer.
The scope of this variable is outside the loop so this prevent
cache corruption based on using the mainPath value from previous
module.

This property is added as needed in our legacy SpacePen views, and is

Previously, the emitter didn't return the new type of grammar, just an undefined to signal when the grammar changed. This patch makes it so that the type of grammar is returned when the texteditor's grammar changes, as per what the API says it does
@kevinsawicki:
That way in the case where a custom editor is opened that isn't a text editor,
it won't blow up if the custom editor doesn't implement setCursorBufferPosition.
Before, values loaded from the config file were set in a
way that allowed any key to be set in the root object.
Now, these values are set in a way that's similar to how
::set works.
Previously, a transaction was used to set an undo grouping interval
for every editor command except `undo` and `redo`. The problem is
that currently, moving a marker inside of a transaction causes the
buffer's redo stack to be cleared. For now, just don't use
transactions for commands that don't modify the buffer's contents."
Replacing WorkspaceView::eachEditorView with Workspace::observeTextEditors
doesn't quite work for this use case. Getting this package to work without
deprecated APIs will probably require further changes to core.
It now takes two arguments, a model constructor and a create view
callback that is passed the model.

Atom is rapidly approaching 1.0. Much of the effort leading up to the 1.0 has been cleaning up APIs in an attempt to future proof, and make a more pleasant experience developing packages.
This document will guide you through the large bits of upgrading your package to work with 1.0 APIs.
## TL;DR
We've set deprecation messages and errors in strategic places to help make sure you don't miss anything. You should be able to get 95% of the way to an updated package just by fixing errors and deprecations. There are a couple of things you can do to get the full effect of all the errors and deprecations.
### Use atom-space-pen-views
If you use any class from `require 'atom'` with a `$` or `View` in the name, add the `atom-space-pen-views` module to your package's `package.json` file's dependencies:
```js
{
"dependencies":{
"atom-space-pen-views":"^2.0.3"
}
}
```
Then run `apm install` in your package directory.
### Require views from atom-space-pen-views
Anywhere you are requiring one of the following from `atom` you need to require them from `atom-space-pen-views` instead.
```coffee
# require these from 'atom-space-pen-views' rather than 'atom'
You wrote specs, right!? Here's where they shine. Run them with `cmd-shift-P`, and search for `run package specs`. It will show all the deprecation messages and errors.
### Update the engines field in package.json
When you are deprecation free and all done converting, upgrade the `engines` field in your package.json:
```json
{
"engines":{
"atom":">=0.174.0, <2.0.0"
}
}
```
### Examples
We have upgraded all the core packages. Please see [this issue](https://github.com/atom/atom/issues/4011) for a link to all the upgrade PRs.
## Deprecations
All of the methods in Atom core that have changes will emit deprecation messages when called. These messages are shown in two places: your **package specs**, and in **Deprecation Cop**.
### Specs
Just run your specs, and all the deprecations will be displayed in yellow.
Run an atom window in dev mode (`atom -d`) with your package loaded, and open Deprecation Cop (search for `deprecation` in the command palette). Deprecated methods will be appear in Deprecation Cop only after they have been called.
When deprecation cop is open, and deprecated methods are called, a `Refresh` button will appear in the top right of the Deprecation Cop interface. So exercise your package, then come back to Deprecation Cop and click the `Refresh` button.
## Upgrading your Views
Previous to 1.0, views were baked into Atom core. These views were based on jQuery and `space-pen`. They looked something like this:
```coffee
# The old way: getting views from atom
{$,TextEditorView,View}=require'atom'
module.exports =
classSomeViewextendsView
@content: ->
@divclass:'find-and-replace',=>
@divclass:'block',=>
@subview'myEditor',newTextEditorView(mini: true)
#...
```
### The New
`require 'atom'` no longer provides view helpers or jQuery. Atom core is now 'view agnostic'. The preexisting view system is available from a new npm package: `atom-space-pen-views`.
`atom-space-pen-views` now provides jQuery, `space-pen` views, and Atom specific views:
```coffee
# These are now provided by atom-space-pen-views
$
$$
$$$
View
TextEditorView
ScrollView
SelectListView
```
### Adding the module dependencies
To use the new views, you need to specify the `atom-space-pen-views` module in your package's `package.json` file's dependencies:
```js
{
"dependencies":{
"atom-space-pen-views":"^2.0.3"
}
}
```
`space-pen` bundles jQuery. If you do not need `space-pen` or any of the views, you can require jQuery directly.
```js
{
"dependencies":{
"jquery":"^2"
}
}
```
### Converting your views
Sometimes it is as simple as converting the requires at the top of each view page. I assume you read the 'TL;DR' section and have updated all of your requires.
### Upgrading classes extending any space-pen View
#### `afterAttach` and `beforeRemove` updated
The `afterAttach` and `beforeRemove` hooks have been replaced with
`attached` and `detached` and the semantics have changed.
`afterAttach` was called whenever the node was attached to another DOM node, even if that parent node wasn't present in the DOM. `afterAttach` also was called with a boolean indicating whether or not the element and its parents were on the DOM. Now the `attached` hook is _only_ called when the node and all of its parents are actually on the DOM, and is not called with a boolean.
`beforeRemove` was only called when `$.fn.remove` was called, which was typically used when the node was completely removed from the DOM. The new `detached` hook is called whenever the DOM node is _detached_, which could happen if the node is being detached for reattachment later. In short, if `beforeRemove` is called the node is never coming back. With `detached` it might be attached again later.
```coffee
# Old way
{View}=require'atom'
classMyViewextendsView
afterAttach: (onDom) ->
#...
beforeRemove: ->
#...
```
```coffee
# New way
{View}=require'atom-space-pen-views'
classMyViewextendsView
attached: ->
# Always called with the equivalent of @afterAttach(true)!
#...
detached: ->
#...
```
#### `subscribe` and `subscribeToCommand` methods removed
The `subscribe` and `subscribeToCommand` methods have been removed. See the Eventing and Disposables section for more info.
### Upgrading to the new TextEditorView
All of the atom-specific methods available on the `TextEditorView` have been moved to the `TextEditor`, available via `TextEditorView::getModel`. See the [`TextEditorView` docs][TextEditorView] and [`TextEditor` docs][TextEditor] for more info.
### Upgrading classes extending ScrollView
The `ScrollView` has very minor changes.
You can no longer use `@off` to remove default behavior for `core:move-up`, `core:move-down`, etc.
```coffee
# Old way to turn off default behavior
classResultsViewextendsScrollView
initialize: (@model) ->
super()
# turn off default scrolling behavior from ScrollView
@off'core:move-up'
@off'core:move-down'
@off'core:move-left'
@off'core:move-right'
```
```coffee
# New way to turn off default behavior
classResultsViewextendsScrollView
initialize: (@model) ->
disposable = super()
# turn off default scrolling behavior from ScrollView
disposable.dispose()
```
* Check out [an example](https://github.com/atom/find-and-replace/pull/311/files#diff-9) from find-and-replace.
* See the [docs][ScrollView] for all the options.
### Upgrading classes extending SelectListView
Your SelectListView might look something like this:
This attaches and detaches itself from the dom when toggled, canceling magically detaches it from the DOM, and it uses the classes `overlay` and `from-top`.
The new SelectListView no longer automatically detaches itself from the DOM when cancelled. It's up to you to implement whatever cancel beahavior you want. Using the new APIs to mimic the sematics of the old class, it should look like this:
```coffee
# New!
classCommandPaletteViewextendsSelectListView
initialize: ->
super()
# no more need for the `overlay` and `from-top` classes
# You need to implement the `cancelled` method and hide.
cancelled: ->
@hide()
confirmed: ({name, jQuery}) ->
@cancel()
# do something with the result
toggle: ->
# Toggling now checks panel visibility,
# and hides / shows rather than attaching to / detaching from the DOM.
if@panel?.isVisible()
@cancel()
else
@show()
show: ->
# Now you will add your select list as a modal panel to the workspace
@panel?=atom.workspace.addModalPanel(item: this)
@panel.show()
@storeFocusedElement()
items = []# TODO: build items
@setItems(items)
@focusFilterEditor()
hide: ->
@panel?.hide()
```
* And check out the [conversion of CommandPaletteView][selectlistview-example] as a real-world example.
* See the [SelectListView docs][SelectListView] for all options.
## Using the model layer rather than the view layer
The API no longer exposes any specialized view objects or view classes. `atom.workspaceView`, and all the view classes: `WorkspaceView`, `EditorView`, `PaneView`, etc. have been globally deprecated.
Nearly all of the atom-specific actions performed by the old view objects can now be managed via the model layer. For example, here's adding a panel to the interface using the `atom.workspace` model instead of the `workspaceView`:
```coffee
# Old!
div = document.createElement('div')
atom.workspaceView.appendToTop(div)
```
```coffee
# New!
div = document.createElement('div')
atom.workspace.addTopPanel(item: div)
```
For actions that still require the view, such as dispatching commands or munging css classes, you'll access the view via the `atom.views.getView()` method. This will return a subclass of `HTMLElement` rather than a jQuery object or an instance of a deprecated view class (e.g. `WorkspaceView`).
`atom.workspaceView`, the `WorkspaceView` class and the `EditorView` class have been deprecated. These two objects are used heavily throughout specs, mostly to dispatch events and commands. This section will explain how to remove them while still retaining the ability to dispatch events and commands.
### Removing WorkspaceView references
`WorkspaceView` has been deprecated. Everything you could do on the view, you can now do on the `Workspace` model.
Requiring `WorkspaceView` from `atom` and accessing any methods on it will throw a deprecation warning. Many specs lean heavily on `WorkspaceView` to trigger commands and fetch `EditorView` objects.
Your specs might contain something like this:
```coffee
# Old!
{WorkspaceView}=require'atom'
describe'FindView',->
beforeEach->
atom.workspaceView = newWorkspaceView()
```
Instead, we will use the `atom.views.getView()` method. This will return a plain `HTMLElement`, not a `WorkspaceView` or jQuery object.
The workspace needs to be attached to the DOM in some cases. For example, view hooks only work (`attached()` on `View`, `attachedCallback()` on custom elements) when there is a descendant attached to the DOM.
You might see this in your specs:
```coffee
# Old!
atom.workspaceView.attachToDom()
```
Change it to:
```coffee
# New!
jasmine.attachToDOM(workspaceElement)
```
### Removing EditorView references
Like `WorkspaceView`, `EditorView` has been deprecated. Everything you needed to do on the view you are now able to do on the `TextEditor` model.
In many cases, you will not even need to get the editor's view anymore. Any of those instances should be updated to use the `TextEditor` instance instead. You should really only need the editor's view when you plan on triggering a command on the view in a spec.
Your specs might contain something like this:
```coffee
# Old!
describe'Something',->
[editorView]=[]
beforeEach->
editorView = atom.workspaceView.getActiveView()
```
We're going to use `atom.views.getView()` again to get the editor element. As in the case of the `workspaceElement`, `getView` will return a subclass of `HTMLElement` rather than an `EditorView` or jQuery object.
```coffee
# New!
describe'Something',->
[editor,editorElement]=[]
beforeEach->
editor = atom.workspace.getActiveTextEditor()
editorElement = atom.views.getView(editor)
```
### Dispatching commands
Since the `editorElement` objects are no longer `jQuery` objects, they no longer support `trigger()`. Additionally, Atom has a new command dispatcher, `atom.commands`, that we use rather than commandeering jQuery's `trigger` method.
A couple large things changed with respect to events:
1. All model events are now exposed as event subscription methods that return [`Disposable`][disposable] objects
1. The `subscribe()` method is no longer available on `space-pen``View` objects
1. An Emitter is now provided from `require 'atom'`
### Consuming Events
All events from the Atom API are now methods that return a [`Disposable`][disposable] object, on which you can call `dispose()` to unsubscribe.
```coffee
# Old!
editor.on'changed',->
```
```coffee
# New!
disposable = editor.onDidChange->
# You can unsubscribe at some point in the future via `dispose()`
disposable.dispose()
```
Deprecation warnings will guide you toward the correct methods.
#### Using a CompositeDisposable
You can group multiple disposables into a single disposable with a `CompositeDisposable`.
```coffee
{CompositeDisposable}=require'atom'
classSomething
constructor: ->
editor = atom.workspace.getActiveTextEditor()
@disposables = newCompositeDisposable
@disposables.addeditor.onDidChange->
@disposables.addeditor.onDidChangePath->
destroy: ->
@disposables.dispose()
```
### Removing View::subscribe and Subscriber::subscribe calls
There were a couple permutations of `subscribe()`. In these examples, a `CompositeDisposable` is used as it will commonly be useful where conversion is necessary.
#### subscribe(unsubscribable)
This one is very straight forward.
```coffee
# Old!
@subscribeeditor.on'changed',->
```
```coffee
# New!
disposables = newCompositeDisposable
disposables.addeditor.onDidChange->
```
#### subscribe(modelObject, event, method)
When the modelObject is an Atom model object, the change is very simple. Just use the correct event method, and add it to your CompositeDisposable.
Things are a little more complicated when subscribing to a DOM or jQuery element. Atom no longer provides helpers for subscribing to elements. You can use jQuery or the native DOM APIs, whichever you prefer.
```coffee
# Old!
@subscribe$(window),'focus',->
```
```coffee
# New!
{Disposable,CompositeDisposable}=require'atom'
disposables = newCompositeDisposable
# New with jQuery
focusCallback = ->
$(window).on'focus',focusCallback
disposables.addnewDisposable->
$(window).off'focus',focusCallback
# New with native APIs
focusCallback = ->
window.addEventListener'focus',focusCallback
disposables.addnewDisposable->
window.removeEventListener'focus',focusCallback
```
### Providing Events: Using the Emitter
You no longer need to require `emissary` to get an emitter. We now provide an `Emitter` class from `require 'atom'`. We have a specific pattern for use of the `Emitter`. Rather than mixing it in, we instantiate a member variable, and create explicit subscription methods. For more information see the [`Emitter` docs][emitter].
```coffee
# New!
{Emitter}=require'atom'
classSomething
constructor: ->
@emitter = newEmitter
destroy: ->
@emitter.dispose()
onDidChange: (callback) ->
@emitter.on'did-change',callback
methodThatFiresAChange: ->
@emitter.emit'did-change',{data: 2}
# Using the evented class
something = newSomething
something.onDidChange(eventObject) ->
console.logeventObject.data# => 2
something.methodThatFiresAChange()
```
## Subscribing To Commands
`$.fn.command` and `View::subscribeToCommand` are no longer available. Now we use `atom.commands.add`, and collect the results in a `CompositeDisposable`. See [the docs][commands-add] for more info.
# You can register commands directly on individual DOM elements in addition to
# using selectors. When in a View class, you should have a `@element` object
# available. `@element` is a plain HTMLElement object
@disposables.addatom.commands.add@element,
'core:close':->
'core:cancel':->
```
