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.
* Add missing documentation for a couple existing flags.
* Make each flag its own header, so it gets an anchor, and can be permalinked
to.
* Streamline some content and descriptions.
* Try to enable all webidls
* Separate out unavailable webidl files by reason.
* Create record of fully tested WebIDL files
* Update notes to reflect new situation with web-idl
* Make a blank ident fail, disable the necessary widls.
It turns out that all the blank idents came from blank enum variants,
which is allowed in webidl apparently.
* Added passing-data readme entry
* Added the file
* Changed wording, and fixed hyperlinks
* Another attempt at fixing links
* Changed highlighting of key words
* Fixed typo
* Add some notes about viewing bindings output.
I found this helpful when debugging, so I thought others might too.
* Fix formatting
* Another formatting fix
* 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
* 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
* tests: Add newlines between impl methods for Project
* WIP headless browser testing with geckodriver and selenium
* Get some more of headless testing working
* Extract `console.log` invocations and print them from the console
* Ship the error message from an exception from the browser back to the command
line
* Cleanup some "if headless" and `else` branches
* Fix killing `webpack-dev-server` in the background with `--watch-stdin`
* Fix path appending logic for Windows
* Always log logs/errors in headless mode
* Install Firefox on Travis
* Don't duplicate full test suite with `yarn`
No need to run that many tests, we should be able to get by with a smoke test
that it just works.
* headless tests: Move `run-headless.js` to its own file and `include_str!` it
* Run `rustfmt` on `tests/all/main.rs`
* guide: Add note about headless browser tests and configuration
* test: Log WASM_BINDGEN_FIREFOX_BIN_PATH in run-headless.js
* TEMP only run add_headless test in CI
* Add more logging to headless testing
* Allow headless tests to run for 60 seconds before timeout
* TEMP add logging to add_headless test
* Fix headless browser tests
* Another attempt to fix Travis
* More attempts at debugging
* Fix more merge conflicts
* Touch up an error message
* Fixup travis again
* Enable all travis tests again
* Test everything on AppVeyor
