object instance describing the revision. Available fields of the
RevisionInfo may vary based on the options used by the UI when it
loaded the change.
[[context_project]]
=== context.project

=== HTML Helpers
The link:#ActionContext[action context] includes some HTML helper
functions to make working with DOM based widgets less painful.
* `br()`: new `<br>` element.
* `button(label, options)`: new `<button>` with the string `label`
wrapped inside of a `div`. The optional `options` object may
define `onclick` as a function to be invoked upon clicking. This
calling pattern avoids circular references between the element
and the onclick handler.
* `checkbox()`: new `<input type='checkbox'>` element.
* `div(...)`: a new `<div>` wrapping the (optional) arguments.
* `hr()`: new `<hr>` element.
* `label(c, label)`: a new `<label>` element wrapping element `c`
and the string `label`. Used to wrap a checkbox with its label,
`label(checkbox(), 'Click Me')`.
* `prependLabel(label, c)`: a new `<label>` element wrapping element `c`
and the string `label`. Used to wrap an input field with its label,
`prependLabel('Greeting message', textfield())`.
* `textarea(options)`: new `<textarea>` element. The options
object may optionally include `rows` and `cols`. The textarea
comes with an onkeypress handler installed to play nicely with
Gerrit's keyboard binding system.
* `textfield()`: new `<input type='text'>` element. The text field
comes with an onkeypress handler installed to play nicely with
Gerrit's keyboard binding system.
* `select(a,i)`: a new `<select>` element containing one `<option>`
element for each entry in the provided array `a`. The option with
the index `i` will be pre-selected in the drop-down-list.
* `selected(s)`: returns the text of the `<option>` element that is
currently selected in the provided `<select>` element `s`.
* `span(...)`: a new `<span>` wrapping the (optional) arguments.
* `msg(label)`: a new label.
[[ScreenContext]]

each time the user navigates to a matching URL.
[[screen_body]]
=== screen.body
Empty HTML `<div>` node the plugin should add its content to. The
node is already attached to the document, but is invisible. Plugins
must call `screen.show()` to display the DOM node. Deferred display
allows an implementor to partially populate the DOM, make remote HTTP
requests, finish populating when the callbacks arrive, and only then
make the view visible to the user.
[[screen_token]]
=== screen.token
URL token fragment that activated this screen. The value is identical
to `screen.token_match[0]`. If the URL is `/#/x/hello/list` the token
will be `"list"`.

This is identical to the result of RegExp.exec. Index 0 contains the
entire matching expression; index 1 the first matching group, etc.
