This could be done by each application, but it does cost only a few
lines of code, and it helps standardizing the Owl ecosystem.
For example, some library (such as o_spreadsheet) needs to mock side
effects, and Odoo also needs to do that, so this prevents duplicated effort.

This new t-set-slot directive is meant to replace t-set when we need to
define the content of a sub slot. All new code should use that
directive.
The old t-set directive is still supported for now, but this should be
removed when we publish Owl 2.0.
In this commit, we uses the "!" as suffix to designate an event that
should be captured. This is inspired by the Vue source code.
This solves the issue of communicating additional information to the
underlying virtual dom. However, this will most likely disappear when
we rewrite the vdom as a virtual block system.

In most cases, we just want Component<any, Env>. But since it was so
annoying to have always the type Env, we actually used
Component<any,any> everywhere.
With this commit, the generic types have a default (and their order is
swapped), so we can simply use Component in most cases, and
Component<Props> when we want to type the props.
This commit adds the support of the & selector.
This selector is useful to join a subrule with a parent selector.
example:
button {
&:hover {
background-color: red;
}
}
will give
button:hover {
background-color: red;
}
Before this commit, the handlers were bound to the current context,
which is often the component but not necessarily. In some cases, a sub
scope can be created (with t-foreach, or slots, or t-call), and the
context is actually an object with the actual component instance it its
prototype chain, but not the component.
A component can now be mounted in different positions: either 'before' (at
the start), 'after' (at the end), or 'attach' (take possession of a target
element)

The component Portal is used to teleport the content
in its slot as a child of an element
somewhere else in the DOM, usually 'body'
It is designed to be transparent and is just here to do the teleportation task
OwlEvents (with method `Component.trigger`) are redirected from
any Component instanciated within the Portal (and therefore teleported
somewhere else) to the place it would have been without teleportation
i.e. they are re-triggered onto the Portal root node

Before this rev, using t-component on a div (for example) node
would silently ignore the div and replace it by the root node of
the component. A way to improve this was to create an extra div
node and to put the component inside it. However, it raised
questions: what do we do with other attributes set on this tag?
Do we apply them on the div, or on the component? In addition,
some of them only make sense on the component (e.g. props), so we
have to detect them. Whatever we would have decided, it wouldn't
have been obvious from the user point of view, so we chose not to
support it, and we thus now raise an error in this case.
Closes#487.
including:
- add a link to the tutorial in the main readme page
- remove learning page on 'env', move content on reference page
- add dynamic sub components section in component page
- add reference page on props
- split qweb page into engine/language pages
- move t-key information into qweb language page
Re-render the component all the time before remounting it, which
seems safer anyway.
In the test, we had to add a nextTick to wait for the changes to
be notified (before, we waited thanks to the additional call to
mount). If we don't do the nextTick, mount is called, and render
is called right after (before the promise returned by mount is
resolved). This scenario doesn't work right now (see #441).
Closes#381
This is a partial revert of commit 7d249d6f09.
The reason is that this changes made it much harder to unit test
components. Before, we could simply instantiate a component
like this:
const my|Comp = new MyComponent(null, props);
and then simply test it. This commit reestablish that possibility.
