* Adding in initial support for all HTML*Element interfaces.
* Fix camelcasing of short HTML interface names
* Disabling span test as breaks on taskcluster
It looks like these are primarily targeted at informing whether functionality is
either on web workers, windows, or both. For now we'll generate the same
bindings regardless, and users will need to be proactive about what they're
using. In that case there shouldn't be any need for us to process these, so
avoid warning about them!
* Bump to 0.2.12
* Update all version numbers and deps
* Update all listed authors to `["The wasm-bindgen Developers"]`
* Update `repository` links to specific paths for each crate
* Update `homepage` links to the online book
* Update all links away from `alexcrichton/wasm-bindgen`
* Add `#[doc]` directives for HTML URLs
* Update more version requirements
* Fill out CHANGELOG
* Shard the `convert.rs` module into sub-modules
Hopefully this'll make the organization a little nicer over time!
* Start adding support for optional types
This commit starts adding support for optional types to wasm-bindgen as
arguments/return values to functions. The strategy here is to add two new
traits, `OptionIntoWasmAbi` and `OptionFromWasmAbi`. These two traits are used
as a blanket impl to implement `IntoWasmAbi` and `FromWasmAbi` for `Option<T>`.
Some consequences of this design:
* It should be possible to ensure `Option<SomeForeignType>` implements to/from
wasm traits. This is because the option-based traits can be implemented for
foreign types.
* A specialized implementation is possible for all types, so there's no need for
`Option<T>` to introduce unnecessary overhead.
* Two new traits is a bit unforutnate but I can't currently think of an
alternative design that works for the above two constraints, although it
doesn't mean one doesn't exist!
* The error messages for "can't use this type here" is actually halfway decent
because it says these new traits need to be implemented, which provides a good
place to document and talk about what's going on here!
* Nested references like `Option<&T>` can't implement `FromWasmAbi`. This means
that you can't define a function in Rust which takes `Option<&str>`. It may be
possible to do this one day but it'll likely require more trait trickery than
I'm capable of right now.
* Add support for optional slices
This commit adds support for optional slice types, things like strings and
arrays. The null representation of these has a pointer value of 0, which should
never happen in normal Rust. Otherwise the various plumbing is done throughout
the tooling to enable these types in all locations.
* Fix `takeObject` on global sentinels
These don't have a reference count as they're always expected to work, so avoid
actually dropping a reference on them.
* Remove some no longer needed bindings
* Add support for optional anyref types
This commit adds support for optional imported class types. Each type imported
with `#[wasm_bindgen]` automatically implements the relevant traits and now
supports `Option<Foo>` in various argument/return positions.
* Fix building without the `std` feature
* Actually fix the build...
* Add support for optional types to WebIDL
Closes#502
Add support for the primitive type arrays, and additionally switch `ByteString`
to `String` instead of `Vec<u8>` according to the online documentation.
* clippy: it is more idiomatic to loop over references to containers instead of using explicit iteration methods
* clippy: useless use of `format!`
* clippy: if/else is an expression
* clippy: use of followed by a function call
* clippy: large size difference between variants
* clippy: redundant closure
* Revert "clippy: large size difference between variants"
This reverts commit 7e2e660dd4.
* Revert "clippy: it is more idiomatic to loop over references to containers instead of using explicit iteration methods"
This reverts commit 5c4804f790.
This is a major change to how webidl is processed. This adds
a two phase process, where the first phase records the names of
various types and indexes the mixins (and might do more in the
future). The actual program building happens in the second phase.
As part of this, this also makes it so that interface objects
are passed by reference, rather than by value. The spec isn't
exactly clear on this, but Mozilla's C++ reflection suggestions
seem to indicate that they should be passed by reference (see
https://developer.mozilla.org/en-US/docs/Mozilla/WebIDL_bindings).
This sets the `catch` flag on the emitted AST when an operation/attribute has
the `[Throws]` extended attribute on it.
Additionally, constructors aren't annotated with `[Throws]` but can still throw
exceptions, so we must conservatively assume *every* constructor can throw an
error.
* Create a new `web-sys` crate
This will eventually contain all the WebIDL-generated bindings to Web APIs.
* ci: Test the new `web-sys` crate in CI
* web-sys: Add a small README
* web-sys: Vendor all the WebIDL files from mozilla-central
* backend: Add a pass to remove AST items that use undefined imports
This is necessary for the WebIDL frontend, which can't translate many WebIDL
constructs into equivalent wasm-bindgen AST things yet. It lets us make
incremental progress: we can generate bindings to methods we can support right
now even though there might be methods on the same interface that we can't
support yet.
* webidl: Add a bunch of missing semicolons
* webidl: Make parsing private
It was only `pub` so that we could test it, but we ended up moving towards
integration tests rather than unit tests that assert particular ASTs are parsed
from WebIDL files.
* webidl: Remove uses of undefined import types
* test-project-builder: Build projects in "very verbose" mode
This helps for debugging failing WebIDL-related tests.
* test-project-builder: Add more profiling timers
* test-project-builder: Detect when webpack-dev-server fails
Instead of going into an infinite loop, detect when webpack-dev-server fails to
start up and early exit the test.
* webidl: Specify version for dev-dependency on wasm-bindgen-backend
Instead of only a relative path.
* guide: Add section about contributing to `web-sys`
* WIP enable Event.webidl
Still need to fix and finish the test.
* Update expected webidl output
* Start out a test's status as incomplete
That way if we don't fill it in the error message doesn't look quite so bizarre
* Fix onerror function in headless mode
Otherwise we don't see any output!
* Fix package.json/node_modules handling in project generation
Make sure these are looked up in the git project root rather than the crate root
* Avoid logging body text
This was meant for debugging and is otherwise pretty noisy
* Fix a relative path
* More expected test fixes
* Fix a typo
* test-project-builder: Allow asynchronous tests
* webidl: Convert [Unforgeable] attributes into `#[wasm_bindgen(structural)]`
Fixes#432
* test-project-builder: Print generated WebIDL bindings for debugging purposes
Helps debug bad WebIDL bindings generation inside tests.
* When we can't find a descriptor, say which one can't be found
This helps when debugging things that need to become structural.
* web-sys: Test bindings for Event
* ci: Use `--manifest-path dir` instead of `cd dir && ...`
* web-sys: Just move .webidl files isntead of symlinking to enable them
* tests: Polyfill Array.prototype.values for older browsers in CI
* test-project-builder: Don't panic on poisoned headless test mutex
We only use it to serialize headless tests so that we don't try to bind the port
concurrently. Its OK to run another headless test if an earlier one panicked.
* JsValue: Add {is,as}_{object,function} methods
Allows dynamically casting values to `js::Object` and `js::Function`.
* tidy: Fix whitespace and missing semicolons
* Allow for dynamic feature detection of methods
If we create bindings to a method that doesn't exist in this implementation,
then it shouldn't fail until if/when we actually try and invoke that missing
method.
* tests: Do feature detection in Array.prototype.values test
* Add JsValue::{is_string, as_js_string} methods
And document all the cast/convert/check methods for js value.
* eslint: allow backtick string literals
* Only generate a fallback import function for non-structural imports
* remove BindgenAttrs from other backend::ast structs
This is primarily a tool for use with the macro crate. Most of
these attributes were ignored in the actual codegen, but a few
were still being used. This is confusing when trying to add
other sources for codegen (such as webidl and typescript).
* move parsing logic to macro crate
This makes the backend crate solely concerned with having an ast
for which we can generate code.
* No need for version deps in dev-deps
These are all internal so we can drop the version
* Remove wasm-bindgen-cli's parity-wasm dep
No longer needed
* Tweak file hierarchy in webidl tests
Use Cargo's conventions to avoid the need to define `[[test]]` sections
* Remove unused imports
This is still a work in progress. Parse WebIDL source text and convert it into
wasm-bindgen AST, so that we can automatically emit bindings for the types and
functions described in the WebIDL.
