(That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. + info.decl = b.variableDeclaration("var", [ + b.variableDeclarator( + blockPath.scope.declareTemporary("marked"), + b.callExpression( + b.memberExpression( + b.arrayExpression([]), + b.identifier("map"), + false + ), + [runtimeProperty("mark")] + ) + ) + ]); + + for (var i = 0; i < block.body.length; ++i) { + if (!shouldNotHoistAbove(blockPath.get("body", i))) { + break; + } + } -module.exports = Transform; + blockPath.get("body").insertAt(i, info.decl); -var Duplex = require('./_stream_duplex'); + return info.decl; + } -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ + function shouldNotHoistAbove(stmtPath) { + var value = stmtPath.value; + n.Statement.assert(value); -util.inherits(Transform, Duplex); + // If the first statement is a "use strict" declaration, make sure to + // insert hoisted declarations afterwards. + return n.ExpressionStatement.check(value) && + n.Literal.check(value.expression) && + value.expression.value === "use strict"; + } + function renameArguments(funcPath, argsId) { + assert.ok(funcPath instanceof types.NodePath); + var func = funcPath.value; + var didReplaceArguments = false; + var hasImplicitArguments = false; -function TransformState(options, stream) { - this.afterTransform = function(er, data) { - return afterTransform(stream, er, data); - }; + recast.visit(funcPath, { + visitFunction: function(path) { + if (path.value === func) { + hasImplicitArguments = !path.scope.lookup("arguments"); + this.traverse(path); + } else { + return false; + } + }, - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; -} + visitIdentifier: function(path) { + if (path.value.name === "arguments") { + var isMemberProperty = + n.MemberExpression.check(path.parent.node) && + path.name === "property" && + !path.parent.node.computed; -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; + if (!isMemberProperty) { + path.replace(argsId); + didReplaceArguments = true; + return false; + } + } - var cb = ts.writecb; + this.traverse(path); + } + }); - if (!cb) - return stream.emit('error', new Error('no writecb in Transform class')); + // If the traversal replaced any arguments identifiers, and those + // identifiers were free variables, then we need to alias the outer + // function's arguments object to the variable named by argsId. + return didReplaceArguments && hasImplicitArguments; + } - ts.writechunk = null; - ts.writecb = null; + var awaitVisitor = types.PathVisitor.fromMethodsObject({ + visitFunction: function(path) { + return false; // Don't descend into nested function scopes. + }, - if (!util.isNullOrUndefined(data)) - stream.push(data); + visitAwaitExpression: function(path) { + // Convert await and await* expressions to yield expressions. + var argument = path.value.argument; + + // If the parser supports await* syntax using a boolean .all property + // (#171), desugar that syntax to yield Promise.all(argument). + if (path.value.all) { + argument = b.callExpression( + b.memberExpression( + b.identifier("Promise"), + b.identifier("all"), + false + ), + [argument] + ); + } - if (cb) - cb(er); + // Transforming `await x` to `yield regeneratorRuntime.awrap(x)` + // causes the argument to be wrapped in such a way that the runtime + // can distinguish between awaited and merely yielded values. + return b.yieldExpression( + b.callExpression( + runtimeProperty("awrap"), + [argument] + ), + false + ); + } + }); - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} +},{"..":455,"./emit":449,"./hoist":450,"./util":453,"assert":203,"fs":202,"private":448,"recast":480}],455:[function(require,module,exports){ + (function (__dirname){ + /** + * Copyright (c) 2014, Facebook, Inc. + * All rights reserved. + * + * This source code is licensed under the BSD-style license found in the + * https://raw.github.com/facebook/regenerator/master/LICENSE file.
