* 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 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
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
* Move the `js` module to a `js_sys` crate
* Update js-sys tests to pass again
* Update binding_to_unimplemented_apis_doesnt_break_everything
Remove its dependency on the `js` module
* Update metadata for js-sys
* Fix the `closures` example
* Changed eslintrc to be JSON file (Most projects use JSON version)
* Added .eslintignore to ingore node_modules from subdirectories such as examples
* Ran eslint --fix examples to fix all examples
* Added npm script for running eslint against examples
* Added npm script for running eslint against generated *out* code
* Hooked npm scripts into travis ci to prevent examples from becoming inconsistent with future PR's
