* Gate `web-sys` APIs on activated features
Currently the compile times of `web-sys` are unfortunately prohibitive,
increasing the barrier to using it. This commit updates the crate to instead
have all APIs gated by a set of Cargo features which affect what bindings are
generated at compile time (and which are then compiled by rustc). It's
significantly faster to activate only a handful of features vs all thousand of
them!
A magical env var is added to print the list of all features that should be
generated, and then necessary logic is added to ferry features from the build
script to the webidl crate which then uses that as a filter to remove items
after parsing. Currently parsing is pretty speedy so we'll unconditionally parse
all WebIDL files, but this may change in the future!
For now this will make the `web-sys` crate a bit less ergonomic to use as lots
of features will need to be specified, but it should make it much more
approachable in terms of first-user experience with compile times.
* Fix AppVeyor testing web-sys
* FIx a typo
* Udpate feature listings from rebase conflicts
* Add some crate docs and such
This commit refactors the lowest-level primitive for creating functions into a
new `create_one_function` function. This doesn't take into account overloading
but is suitable for things like `create_{getter,setter}`. Eventually the
overloading will be implemented in terms of this function.
This commit refactors WebIDL code generation to walk over the fields of
`FirstPassRecord` instead of walking the AST again. This helps remove
redundancies like checking `is_chrome_only` as well as revisiting partial
interfaces and such. This should make it more clear that the first pass's job is
to walk the AST and collect all relevant information, while the codegen pass is
purely about appending items to a `Program`.
Additionally this refactoring will also soon be used to prepare different data
structures for operation overloadings, avoiding the need to walk those ASTs
twice.
This commit adds further support for the `Global` attribute to not only emit
structural accessors but also emit functions that don't take `&self`. All
methods on a `[Global]` interface will not require `&self` and will call
functions and/or access properties on the global scope.
This should enable things like:
Window::location() // returns `Location`
Window::fetch(...) // invokes the `fetch` function
Closes#659
Instead of `dom_str`, `byte_str`, and `usv_str`, emit `str` for all of them.
Similarly for `unrestricted_f64` just do `f64` instead. This reflects how we
interpret the types already in terms of Rust types and although technically
makes it possible to have name collisions in WebIDL they don't come up in
practice.
This commit updates how we name overloaded methods. Previously all argument
names were concatenated, but after this commit it only concatenates argument
names where at least one possibility has a different type. Otherwise if all
possibilities have the same type name it in theory isn't adding too much more
information!
Additionally this commit also switches to using `_with_` consistently everywhere
instead of `_with_` for constructors and `_using_` for methods.
Closes#712
This commit adds support for generating bindings for dictionaries defined in
WebIDL. Dictionaries are associative arrays which are simply objects in JS with
named keys and some values. In Rust given a dictionary like:
dictionary Foo {
long field;
};
we'll generate a struct like:
pub struct Foo {
obj: js_sys::Object,
}
impl Foo {
pub fn new() -> Foo { /* make a blank object */ }
pub fn field(&mut self, val: i32) -> &mut Self {
// set the field using `js_sys::Reflect`
}
}
// plus a bunch of AsRef, From, and wasm abi impls
At the same time this adds support for partial dictionaries and dictionary
inheritance. All dictionary fields are optional by default and hence only have
builder-style setters, but dictionaries can also have required fields. Required
fields are exposed as arguments to the `new` constructor.
Closes#241
First added in #161 this never ended up panning out, so let's remove the
experimental suport which isn't actually used by anything today and hold off on
any other changes until an RFC happens.
This commit moves the `webidl/tests` folder to a new `crates/webidl-tests` crate
(to have a test-only build script) and ports them to the `#[wasm_bindgen_test]`
attribute, which should hopefully make testing much speedier for execution!
