The slot inner working has been reworked. A prop "slots" is now passed
explicitely to the component. It looks like
{ slotName_1: slotInfo_1, ..., slotName_m: slotInfo_m }
with the objects slotInfo_i with mandatory keys "__render", "__ctx",
and optional key "__scope" and possibly others.
Here is how a slotInfo object can be created:
A slotInfo object is normally created by setting in a template something
like
<div>
<t t-set-slot="foo" t-set-scope="scope" param_1="var" param_2="3">
content
<t t-esc="scope.bool"/>
<t t-esc="scope.num"/>
</t>
</div>
and it will be used somewhere like
<div>
<t t-esc="props.slots.foo.param_1"/>
<t t-slot="foo" bool="other_var" num="5">
</div>
In the above example, the function "__render" produces the block dom
element for the content of the t-set-slot.
The context "__ctx" will have a key "scope" with value { bool: ..., num: 5 }
and "__scope" will be set to "scope".
Before this commit, errors triggered at the level of the fiber (as opposed to at the level
of a component's rendering), were handled as the very top level of the rendering, that is,
in the scheduler.
This was wrong because components below in the rendering tree would not have a chance to handle their
children's or their own errors.
After this commit, error triggered in willPatch, onMounted and onPatched are correctly handled
at the closest component to where they were thrown.
Have a Child Compnent which has one component that succeeds and another
one that fails at its instanciation.
The Child component handles the Errors by rendering itself.
Before this commit, the error handling algorithm made impossible for the scheduler to finish.
This was because the current fiber was still counted as ongoing, when it was actually completed.
After this commit, this use case is handled correctly.
t-out automatically escaped content when it is a string not marked
with the `markup` function
t-out renders the raw content if it is a Block, or if it has been marked
with the `markup` funtion.
t-esc has been kept since it is safe and is optimized to render text nodes.
all t-raw calls are in fact the same as t-out.
This commit reintroduces some tests for the t-set directive and make
them pass. For that, it was necessary to adapt the qweb compiler in
order to get the following behaviors:
A t-set can affect parent contexts (up to the first parent tagged as
boundary) when the key changed is found in one of the parent contexts.
Some context are marked as boundaries in such a way that
- rendering contexts (e.g. components) cannot be modified via a t-set.
- a t-set in a t-call body or in a called template can never change a
context above the t-call context.
Code prettification has been done.
Snapshots have been modified.
