* Create "babel-helper-wrap-function" It contains the logic to wrap a function inside a call expression. It was part of the "babel-helper-remap-async-to-generator" package, but it is needed to transpile "function.sent" * Create "babel-transform-function-sent" It transforms the "function.sent" meta property by replacing it with "yield" and making the generator ignore the first ".next()" call. * "function.sent" is the last value passed to .next(), not the first one * Disable exec tests on old node * Fix flow error * Add "transform-function-sent" to "stage-2" preset * Do every trasformation in one traversal * Test for "yield function.sent" * [skip ci] * Fix some typos [skip ci]
babel-plugin-transform-function-sent
Compile the
function.sentmeta property, used inside generator functions, to valid ES2015 code.
Example
function* generator() {
console.log("Sent", function.sent);
console.log("Yield", yield);
}
const iterator = generator();
iterator.next(1); // Logs "Sent 1"
iterator.next(2); // Logs "Yield 2"
Is compiled roughly to
let generator = _skipFirstGeneratorNext(function* () {
const _functionSent = yield;
console.log("Sent", _functionSent);
console.log("Yield", yield);
});
const iterator = generator();
iterator.next(1); // Logs "Sent 1"
iterator.next(2); // Logs "Yield 1"
