While Sets have better lookup complexity than arrays, because of the
large constant factors, small arrays can perform better than small sets
when checking for inclusion.
In practice, replacing both of the raw types sets with arrays can
improve performance of reactive-heavy workloads by as much as 30%.
Considering the reactivity code is very hot when rendering data-heavy
components, and the low impact on readability of the fix, the
cost-benefit analysis is clearly in favour of making the fix.
A template set can now obtain a template by calling the function
getTemplate (if any) received in the initial config.
The returned value can be an Element instance, a template string, a
function (i.e. a compiled template), or null. In the last case, owl will
look into the template set rawTemplates object.
Before to this commit, the .trim modifier did not work correctly. The value
in the model is always trim at each input event but not the visual value
in the input. This difference between the visual and the model value cause
few strange bug.
After reflection, we think that we always want to be in .lazy when we use .trim.
Because we want to trim the final value during the onchange event and not
at each input event. If we do it at each input event, we can't write more then
one word easily.
So this commit change the behavior of the .trim modifier to always be in .lazy
For some reason the code of parseXML was duplicated, despite being
exactly the same except for some whitespace. Move it out into a common
utils file.

Previously, having a Function as a type in the static props description
of a component would only work if the component was not the root
component, as the static props description on Component was "any",
whereas the static props description on ComponentConstructor was
"Schema". This meant that static props description on non-root
components was not type-checked, and on root components it was
type-checked only on the mount call.
This commit makes it so that static type description is of type "Schema"
on Component, now causing static props description to be type-checked,
and adds `typeof Function` to the `BaseType` union, which allows
declaring that a component expects a function as a prop.
Closes#1448
With this commit, the templates that are given while instantiating the
App class can be an object with templates not yet parsed (i.e. string,
not Document). This allow to instantiate the App class with templates
that are not yet parsed, and these templates will be parsed only when
needed.

Previously, if a t-set-slot was inside a t-component itself inside a
t-set-slot the parser would crash, because the slot is removed from the
template before compiling its content, causing a further check's
assumption to be broken (the t-set-slot remains connected to the
component's xml node)
This commit adds the following:
- Syntax builder scripts to make syntaxes easier to read and edit
- Syntax highlight in single quote attributes
- Syntax highlight for slot props
- Basic syntax highlight for xpaths
- Added `Switch Below` command
This commit fixes the following:
- Using `Switch Besides` or `Switch Below` does not open a new panel if one was already open
- Fixed missing space in component's snippet indentation
This commit fixes an issue with the highlight element functionality
which would leave the highlight active when the search bar is not empty
and the user changes view. It will now disappear as long as the user
moves his cursor anywhere in the page. Also, highlights are now removed
when the user scrolls while the html selector is active.
Small imp to highlight a component when it gets selected in the tree to
provide better visual feedback to the user when he is using arrow keys
navigation.
Owl Vision is a vscode extension that improves owl developpement by adding
syntax highlights in templates and commands to easly navigate between
components and templates.
It also adds a Component snippet.
Commands:
* `Owl Vision: Find Template`:
- If the cursor is on a template name, finds the corresponding template.
- If the cursor is on a component, finds the template of the selected component.
* `Owl Vision: Find Component`: Finds the selected component definition.
* `Owl Vision: Switch`: Finds the corresponding template or component
depending on the current file.
* `Owl Vision: Switch Besides`: Finds the corresponding template or component
depending on the current file and opens it besides.
Settings:
* `owl-vision.js.include`: Javascript files to include in search.
* `owl-vision.js.exclude`: Javascript files to exclude in search.
* `owl-vision.xml.include`: XML files to include in search.
* `owl-vision.xml.exclude`: XML files to exclude in search.
This commit fixes 2 issues specific to the firefox version of the
extension:
First issue concerns the computation the position of the
border between the subwindows of the components tab which could go
terribly wrong due to the fact that the innerwidth of the window is
implicitly set to 10 when the owl devtools window is hidden.
Second issue comes from changes in the runtime.onMessage method of
browser which now requires to directly return the response instead of
using the sendResponse method.
Also perform a little cleanup on usage of browserInstance and in the
manifest.
`useEffect` type is not compatible with later versions of Typescript.
(I tried with Typescript 5.2, I didn't check which specific
version had the breaking change)
This prevents other projects using owl (such as o-spreadsheet) to
upgrade their own version of Typescript.
`<T extends [...T]>` raises the two following errors:
`Type parameter 'T' has a circular constraint.ts(2313)`
`A rest element type must be an array type.`
This commit adapts the layout of icons in the UI to be more intuitive
and also adds some feedback on hover on some elements for clarity. Also
fixes a bug where an object line could be toggled on select.
This commit prevents the base object prototype from being unfolded when
the env of a component gets unfolded since it does not contain useful
information.
This commit ensures that search results are properly updated when the
components tree is updated so that it remains coherent if search results
appear or disappear from the view.
A few corrections to make the example more realistic:
- The component has no `error` property, so the writer probably meant `state.error`.
- The "content" slot is not being set, and "default" does the job in this case.
- The closing tag was missing in the `ErrorBoundary`'s template.
# v2.2.6
- [IMP] devtools: add svg elements detection
- [FIX] reactivity: do not notify for NOOPs on collections
- [IMP] app: export apps set as static property
- [IMP] runtime: do not check template equality outside dev mode
- [FIX] runtime: properly support t-foreach on strings
This commit extends the detection of component related dom elements to
svg elements in the page so that they can be searched and highlighted
correctly with the devtools.
Previously, if a reactive was observing the presence of an item in a
set that was originally not present, it would get notified when that
item was "deleted" from the set (even though there was nothing to delete
and the set did not change). The same applied to the key already being
present and then being "added". The same thing occured with Map, both
for presence but also for values (setting a key to the value it was
already set to would notify).
This commit fixes that.
Before this commit, Owl would export the list of apps in a global object
`__OWL_DEVTOOLS__`. However, it is sometimes useful to be able to
access that set, even outside of the devtools (for example, to register
templates in all active apps).
closes#1515
When defining a template with a name that the template set already
contains, we currently always check whether the template is the same and
throw an error when it's not. This is potentially expensive as it can
involve serializing a pretty large XML document. This check is only
supposed to help during development so this commit disables this check
outside dev mode.
Previously, support for iterables was added to t-foreach. The idea was
that anything that you can spread or on which you can use for..of would
be supported. Due to an implementation mistakes, strings, which are
iterable were not supported because we checked that the typeof the
iterable was 'object'.
To fix this, we coerce the iterable to an object and check whether that
coerced value has a Symbol.iterator property, which is what happens
behind the scenes when using for..of or spreading a primitive.
Closes: odoo/owl#1503
Firefox will not serialize the xmlns attributes of node inside
XMLDocuments, see https://bugzilla.mozilla.org/show_bug.cgi?id=175946
it will only output an xmlns attribute if the node being serialized has
a non-null namespaceURI.
When compiling templates, we currently use a special attribute,
"block-ns" to keep track of the namespace, but we do not make use of the
namespace to create the elements that will be serialized to the compiled
block string. This causes a difference in behaviour between Chrome and
Firefox: since we end up with an Element with two attributes: the
block-ns attribute and the xmlns attribute. Chrome will serialize both,
but Firefox will only serialize the block-ns because the Element does
not have a namespaceURI.
To fix this issue, we get rid of the block-ns magic attribute
completely, and use xmlns instead. We also use the namespace when
creating intermediate elements that will be used to create the
serialized block string: the namespace is only used to create the
elements but *not* set as an attribute, as this would cause chrome to
serialize it twice, causing a duplicate attribute error when parsing it
further down the line.
When creating the template element for the block at runtime, the xmlns
attribute is used both as the namespace with which to create the
element, and set as an attribute, this doesn't cause issues when
serializing later because the namespaceURI is never serialized as an
attribute when serializing an HTML document[1], so we avoid the
double-serialization in Chrome, and when doing HTML serialization,
Firefox will correctly serialize the attribute.
It's desirable that the xmlns is set as an attribute to allow users to
use owl to render SVG, and then use the HTML serialization of it as a
SVG even outside the context of an HTML document (eg to generate an SVG
file or an SVG data URL).

Because the default content of a t-call is compiled before the block of
the t-call is created, the default content can sometimes incorrectly be
treated as though it is at the root of the template. This causes various
issues, in the case of a t-if, the default content will just replace the
t-call entirely when truthy, and when falsy the template will not return
anything, leading to a crash. Similar things occur with t-foreach and
t-out with a default content.
This commit fixes that by moving the block creation for the t-call ahead
of the compilation of the default content. In doing so, it makes the
context attribute "preventRoot" obsolete: the purpose of this attribute
is to somehow make the code aware that the root of the template will be
defined later, but because it wasn't propagated everywhere properly it
caused this issue. Now that the root already exists before we compile
the default content, we don't need it anymore.
This commit fixes the handling of the inspected path in the
getComponentsTree method so that it is reset when the given one does
not exist anymore. It solves a crash of the method anytime this would
happen which would prevent the tree from updating correctly.
In odoo/owl#1352 we added support for using t-foreach on Map objects,
maps should behave the same as objects where keys are available under
the name specified in t-as and values under that same name with the
suffix `_value`. Unfortunately, because the code for objects was written
in a confusing way (values were stored in a variable named `keys` and
vice versa), the implementation for Map was incorrect and keys and
values were swapped.
This commit fixes that and rewrites the code to be less confusing: keys
are extracted from the variables `k_block` and values from `v_block`,
which swaps the behaviour, and the code to prepare a list from an object
now extracts the keys in `keys` and the values in `values`
Previously, when a template failed to compile because of a syntax error
(typically because we don't do any syntax checking when compiling
expression, allowing invalid expressions to be transpiled successfully),
the error reporting was very minimal: you would only get the error
message itself (eg: "Unexpected token") with the stack information of
the error pointing to the call to `new Function` in owl, which is not
very useful.
This commit catches the compilation error and completes it with
information about the template name when available, and also adds the
generated code to the error message, allowing the user to just
copy/paste it in their web console or code editor to get a more precise
location for the error.
