This change allows the example writer to add doc-region annotations to
files that do not allow comments. This is done by creating a clone of the
file and adding `.annotated` to the file name. This new file can contain
inline `// ...` comments that can be used to annotate the doc regions.
Example:
**package.json**
```
{
"name": "angular.io",
"version": "0.0.0",
"main": "index.js",
"repository": "[email protected]:angular/angular.git",
"author": "Angular",
"license": "MIT",
"private": true,
}
````
**package.json.annotated**
```
{
"name": "angular.io",
// #docregion version
"version": "0.0.0",
// #enddocregion
"main": "index.js",
"repository": "[email protected]:angular/angular.git",
"author": "Angular",
"license": "MIT",
"private": true,
}
````
This region can then be referenced in examples just like any other doc region:
```
{@example 'package.json' region="version"}
```
The rationale of this change is to improve the inter-operability with web
components that might make use of the `<template>` tag.
DEPRECATION
The template tags and template attribute are deprecated:
<template ngFor [ngFor]=items let-item><li>...</li></template>
<li template="ngFor: let item of items">...</li>
should be rewritten as:
<ng-template ngFor [ngFor]=items let-item><li>...</li></ng-template>
Note that they still be supported in 4.x with a deprecartion warning in
development mode.
MIGRATION
- `template` tags (or elements with a `template` attribute) should be rewritten
as a `ng-template` tag,
- `ng-content` selectors should be updated to referto a `ng-template` where they
use to refer to a template: `<ng-content selector="template[attr]">` should be
rewritten as `<ng-content selector="ng-template[attr]">`
- if you consume a component relying on your templates being actual `template`
elements (that is they include a `<ng-content selector="template[attr]">`). You
should still migrate to `ng-template` and make use of `ngProjectAs` to override
the way `ng-content` sees the template:
`<ng-template projectAs="template[attr]">`
- while `template` elements are deprecated in 4.x they continue to work.
