A new directive t-tanslation-context and a new family of directives (of the form
t-translation-context-...) are introduced to allow to translate terms in contexts.
Set t-translation-context="fr" on a node makes every call of the translation
function to be done with "fr" as seconde parameter when translating an
attribute/content within that node or its children (if no closer
t-translation-context directive is found).
A directive t-translation-context-attr="fr" can be used on a node to target its
attribute "attr". For example, if a div has an attribute title="a title",
use t-translation-context-title="pt" will make "a title" to be translated
in the context "pt". Note that this takes precedence over any other directive
t-translation-context found on a parent (or the div itself).
The translation function is in charge of the interpretation of the context: OWL
does not associate any meaning with a translation context.
Before this commit, the template parser would allow using t-esc on a
component tag (<MyComponent t-esc="expr"/>) but would incorrectly ignore
the component when parsing a t-out: <MyComponent t-out="expr"/> would be
parsed as <t t-out="expr"/>
This commit solves the issue, and also, moves the `t-out` parsing code
next to `t-esc` so they have the same priority relatively to other
directives.

Before this commit, owl parser would ignore the `.number` suffix on
<select> options. I do not see a good reason for that, and it prevents
some legitimate usecases.
closes#1444
Before this commit, the `t-on` directive assumed that the next character
would be a -, and ignored it, so if someone would write `t-onclick` by
mistake, Owl would then add an event handler on the `lick` event,
instead of `click`.
With this commit, we improve the parser to make it stricter and fail if
there is no dash.
closes#1441
Before this commit, the parser would remove all consecutive white spaces
for text nodes. After that, the code generator would call the translate
function with the resulting string, which then is different than what we
would expect.
With this commit, we make sure we apply the translation before removing
the additional whitespace. To do that, we have to move the code
processing the string from the parser into the code generator, which
actually makes sense, as the parser should only collect all useful
information without applying too much logic.
closes#1351
Before this commit, a t-set-slot that has no content was not even compiled, and thus not passed
to the component for which it has was defined
After this commit, we allow a t-set-slot to have no content (because it can have slot props)
Before this commit, portal was a Component, now is a directive.
This commit also clean some unused code, and fix an issue on the clean
optimization when a portal is found in a condition or a loop.
The problem was that the compiler is based on the assumption that the
multi block received by the parser only occurs in some cases
where the structure of the template require a multi block, and it does
not work when we have random multiblock elsewhere.
We could fix the issue by modifying the code generator code to support
these usecases, or by simply removing these cases in the parser. Since
this seems more efficient, this is the approach taken by this commit.
Note that it was a good opportunity to simplify the parser.
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".
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.
