This was a file we probably never should have synced out in the first
place. We don't use it and it provides the same basic functionality that
bin/jsx provides.
JSX currently transforms everything to double quote except these two. This way, it's at least consistent and will satisfy half of the people who do put a strict quotation linting on their project.
Test: `jest`, check the double quoted transformed `data-bla="something"`.
Because the JS community's polyfilling infrastructure sucks and we'll
have to fix it for them before we require this.
JSX spread uses React.__spread
(which might get special behavior for key/ref, not sure yet)
This never uses the native implementation and throws for prototype chains.
Once the native implementations are faster, we'll start using them.
The biggest change: instead of calling functions directly, we now use
React.createElement to wrap.
The other big change: this removes the need for the @jsx pragma.
Instead we'll parse everything, assume React is in scope,
and only look for the actual XJS parts in the AST (as opposed to only
runing the transform when @jsx was specified in the docblock).
Note: this is actually a series of commits internally and should have
been syned out in pieces over the past several weeks.
I dropped the part of constants.js that we weren't using (namely the
part where we insert constants) but left it open to do that. It should
be trivial, we just aren't using it.
Fixes#1824
Add support for spread attributes. Transforms into an Object.assign just
like jstransform does for spread properties in object literals.
Depends on https://github.com/facebook/esprima/pull/22
Add harmony transform support in browser
Fixes#1420. Moved some code around in the merge to account for more
changes in the transform code.
Conflicts:
vendor/browser-transforms.js
I implemented this by checking for `type="text/jsx;harmony"`, since this
has a bit of a cleaner implementation rather than parsing a JSON object
out of a data attribute. If in the future there are other options to
pass, it would make sense to move to a system like that.
Along with adding support, there is also a new example added that's
the basic-jsx example with Harmony syntax.
