- //
- // When adding more parser context flags, consider which is the more common case that the
- // flag will be in. This should be the 'false' state for that flag. The reason for this is
- // that we don't store data in our nodes unless the value is in the *non-default* state. So,
- // for example, more often than code 'allows-in' (or doesn't 'disallow-in'). We opt for
- // 'disallow-in' set to 'false'. Otherwise, if we had 'allowsIn' set to 'true', then almost
- // all nodes would need extra state on them to store this info.
- //
- // Note: 'allowIn' and 'allowYield' track 1:1 with the [in] and [yield] concepts in the ES6
- // grammar specification.
- //
- // An important thing about these context concepts. By default they are effectively inherited
- // while parsing through every grammar production. i.e. if you don't change them, then when
- // you parse a sub-production, it will have the same context values as the parent production.
- // This is great most of the time. After all, consider all the 'expression' grammar productions
- // and how nearly all of them pass along the 'in' and 'yield' context values:
- //
- // EqualityExpression[In, Yield] :
- // RelationalExpression[?In, ?Yield]
- // EqualityExpression[?In, ?Yield] == RelationalExpression[?In, ?Yield]
- // EqualityExpression[?In, ?Yield] != RelationalExpression[?In, ?Yield]
- // EqualityExpression[?In, ?Yield] === RelationalExpression[?In, ?Yield]
- // EqualityExpression[?In, ?Yield] !== RelationalExpression[?In, ?Yield]
- //
- // Where you have to be careful is then understanding what the points are in the grammar
- // where the values are *not* passed along. For example:
- //
- // SingleNameBinding[Yield,GeneratorParameter]
- // [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
- // [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt
- //
- // Here this is saying that if the GeneratorParameter context flag is set, that we should
- // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
- // and we should explicitly unset the 'yield' context flag before calling into the Initializer.
- // production. Conversely, if the GeneratorParameter context flag is not set, then we
- // should leave the 'yield' context flag alone.
- //
- // Getting this all correct is tricky and requires careful reading of the grammar to
- // understand when these values should be changed versus when they should be inherited.
- //
- // Note: it should not be necessary to save/restore these flags during speculative/lookahead
- // parsing. These context flags are naturally stored and restored through normal recursive
- // descent parsing and unwinding.

- // character that was completely not understood.
- //
- // 2) A token was expected, but was not present. This type of error is commonly produced
- // by the 'parseExpected' function.
- //
- // 3) A token was present that no parsing function was able to consume. This type of error
- // only occurs in the 'abortParsingListOrMoveToNextToken' function when the parser
- // decides to skip the token.
- //
- // In all of these cases, we want to mark the next node as having had an error before it.

+ // cases do not overlap):
+ // - The completion value when resuming from a `yield` or `yield*`.
+ // - The error value for a catch block.
+ // - The current protected region (array of try/catch/finally/end labels).
+ // - The verb (`next`, `throw`, or `return` method) to delegate to the expression
+ // of a `yield*`.
+ // - The result of evaluating the verb delegated to the expression of a `yield*`.
+ //
+ // functions:
+ // verb(n) Creates a bound callback to the `step` function for opcode `n`.
+ // step(op) Evaluates opcodes in a generator body until execution is suspended or
+ // completed.
+ //
+ // The __generator helper understands a limited set of instructions:
+ // 0: next(value?) - Start or resume the generator with the specified value.
+ // 1: throw(error) - Resume the generator with an exception. If the generator is
+ // suspended inside of one or more protected regions, evaluates
+ // any intervening finally blocks between the current label and
+ // the nearest catch block or function boundary. If uncaught, the
+ // exception is thrown to the caller.
+ // 2: return(value?) - Resume the generator as if with a return. If the generator is
+ // suspended inside of one or more protected regions, evaluates any
+ // intervening finally blocks.
+ // 3: break(label) - Jump to the specified label. If the label is outside of the
+ // current protected region, evaluates any intervening finally
+ // blocks.
+ // 4: yield(value?) - Yield execution to the caller with an optional value. When
+ // resumed, the generator will continue at the next label.
+ // 5: yield*(value) - Delegates evaluation to the supplied iterator. When
+ // delegation completes, the generator will continue at the next
+ // label.
+ // 6: catch(error) - Handles an exception thrown from within the generator body. If
+ // the current label is inside of one or more protected regions,
+ // evaluates any intervening finally blocks between the current
+ // label and the nearest catch block or function boundary. If
+ // uncaught, the exception is thrown to the caller.
+ // 7: endfinally - Ends a finally block, resuming the last instruction prior to
+ // entering a finally block.

+ // Flags that dictate what parsing context we're in. For example:
+ // Whether or not we are in strict parsing mode. All that changes in strict parsing mode is
+ // that some tokens that would be considered identifiers may be considered keywords.
+ //
+ // When adding more parser context flags, consider which is the more common case that the
+ // flag will be in. This should be the 'false' state for that flag. The reason for this is
+ // that we don't store data in our nodes unless the value is in the *non-default* state. So,
+ // for example, more often than code 'allows-in' (or doesn't 'disallow-in'). We opt for
+ // 'disallow-in' set to 'false'. Otherwise, if we had 'allowsIn' set to 'true', then almost
+ // all nodes would need extra state on them to store this info.
+ //
+ // Note: 'allowIn' and 'allowYield' track 1:1 with the [in] and [yield] concepts in the ES6
+ // grammar specification.
+ //
+ // An important thing about these context concepts. By default they are effectively inherited
+ // while parsing through every grammar production. i.e. if you don't change them, then when
+ // you parse a sub-production, it will have the same context values as the parent production.
+ // This is great most of the time. After all, consider all the 'expression' grammar productions
+ // and how nearly all of them pass along the 'in' and 'yield' context values:
+ //
+ // EqualityExpression[In, Yield] :
+ // RelationalExpression[?In, ?Yield]
+ // EqualityExpression[?In, ?Yield] == RelationalExpression[?In, ?Yield]
+ // EqualityExpression[?In, ?Yield] != RelationalExpression[?In, ?Yield]
+ // EqualityExpression[?In, ?Yield] === RelationalExpression[?In, ?Yield]
+ // EqualityExpression[?In, ?Yield] !== RelationalExpression[?In, ?Yield]
+ //
+ // Where you have to be careful is then understanding what the points are in the grammar
+ // where the values are *not* passed along. For example:
+ //
+ // SingleNameBinding[Yield,GeneratorParameter]
+ // [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
+ // [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt
+ //
+ // Here this is saying that if the GeneratorParameter context flag is set, that we should
+ // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
+ // and we should explicitly unset the 'yield' context flag before calling into the Initializer.
+ // production. Conversely, if the GeneratorParameter context flag is not set, then we
+ // should leave the 'yield' context flag alone.
+ //
+ // Getting this all correct is tricky and requires careful reading of the grammar to
+ // understand when these values should be changed versus when they should be inherited.
+ //
+ // Note: it should not be necessary to save/restore these flags during speculative/lookahead
+ // parsing. These context flags are naturally stored and restored through normal recursive
+ // descent parsing and unwinding.

+ // 1) An error that occurred during scanning. For example, an unterminated literal, or a
+ // character that was completely not understood.
+ //
+ // 2) A token was expected, but was not present. This type of error is commonly produced
+ // by the 'parseExpected' function.
+ //
+ // 3) A token was present that no parsing function was able to consume. This type of error
+ // only occurs in the 'abortParsingListOrMoveToNextToken' function when the parser
+ // decides to skip the token.
+ //
+ // In all of these cases, we want to mark the next node as having had an error before it.
+ // With this mark, we can know in incremental settings if this node can be reused, or if
+ // we have to reparse it. If we don't keep this information around, we may just reuse the
+ // node. in that event we would then not produce the same errors as we did before, causing
+ // significant confusion problems.
+ //
+ // Note: it is necessary that this value be saved/restored during speculative/lookahead
+ // parsing. During lookahead parsing, we will often create a node. That node will have
+ // this value attached, and then this value will be set back to 'false'. If we decide to
+ // rewind, we must get back to the same value we had prior to the lookahead.

- /**
- * Any module resolution kind can be augmented with optional settings: 'baseUrl', 'paths' and 'rootDirs' - they are used to
- * mitigate differences between design time structure of the project and its runtime counterpart so the same import name
- * can be resolved successfully by TypeScript compiler and runtime module loader.
- * If these settings are set then loading procedure will try to use them to resolve module name and it can of failure it will
- * fallback to standard resolution routine.
- *
- * - baseUrl - this setting controls how non-relative module names are resolved. If this setting is specified then non-relative
- * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will
- * be '/a/b/c/d'
- * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names
- * will be resolved based on the content of the module name.
- * Structure of 'paths' compiler options
- * 'paths': {
- * pattern-1: [...substitutions],
- * pattern-2: [...substitutions],
- * ...
- * pattern-n: [...substitutions]
- * }
- * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against
- * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case.
- * If pattern contains '*' then to match pattern "<prefix>*<suffix>" module name must start with the <prefix> and end with <suffix>.
- * <MatchedStar> denotes part of the module name between <prefix> and <suffix>.
- * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked.
- * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module
- * from the candidate location.
- * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every
- * substitution in the list and replace '*' with <MatchedStar> string. If candidate location is not rooted it
- * will be converted to absolute using baseUrl.
- * For example:
- * baseUrl: /a/b/c
- * "paths": {
- * // match all module names
- * "*": [
- * "*", // use matched name as is,
- * // <matched name> will be looked as /a/b/c/<matched name>
- *
- * "folder1/*" // substitution will convert matched name to 'folder1/<matched name>',
- * // since it is not rooted then final candidate location will be /a/b/c/folder1/<matched name>
- * ],
- * // match module names that start with 'components/'
- * "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/<matched name> to '/root/components/folder1/<matched name>',
- * // it is rooted so it will be final candidate location
- * }
- *
- * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if
- * they were in the same location. For example lets say there are two files
- * '/local/src/content/file1.ts'
- * '/shared/components/contracts/src/content/protocols/file2.ts'
- * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so
- * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime.
- * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all
- * root dirs were merged together.
- * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
- * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:
- * '/local/src/content/protocols/file2' and try to load it - failure.
- * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
- * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining
- * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.

+ * mitigate differences between design time structure of the project and its runtime counterpart so the same import name
+ * can be resolved successfully by TypeScript compiler and runtime module loader.
+ * If these settings are set then loading procedure will try to use them to resolve module name and it can of failure it will
+ * fallback to standard resolution routine.
+ *
+ * - baseUrl - this setting controls how non-relative module names are resolved. If this setting is specified then non-relative
+ * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will
+ * be '/a/b/c/d'
+ * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names
+ * will be resolved based on the content of the module name.
+ * Structure of 'paths' compiler options
+ * 'paths': {
+ * pattern-1: [...substitutions],
+ * pattern-2: [...substitutions],
+ * ...
+ * pattern-n: [...substitutions]
+ * }
+ * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against
+ * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case.
+ * If pattern contains '*' then to match pattern "<prefix>*<suffix>" module name must start with the <prefix> and end with <suffix>.
+ * <MatchedStar> denotes part of the module name between <prefix> and <suffix>.
+ * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked.
+ * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module
+ * from the candidate location.
+ * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every
+ * substitution in the list and replace '*' with <MatchedStar> string. If candidate location is not rooted it
+ * will be converted to absolute using baseUrl.
+ * For example:
+ * baseUrl: /a/b/c
+ * "paths": {
+ * // match all module names
+ * "*": [
+ * "*", // use matched name as is,
+ * // <matched name> will be looked as /a/b/c/<matched name>
+ *
+ * "folder1/*" // substitution will convert matched name to 'folder1/<matched name>',
+ * // since it is not rooted then final candidate location will be /a/b/c/folder1/<matched name>
+ * ],
+ * // match module names that start with 'components/'
+ * "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/<matched name> to '/root/components/folder1/<matched name>',
+ * // it is rooted so it will be final candidate location
+ * }
+ *
+ * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if
+ * they were in the same location. For example lets say there are two files
+ * '/local/src/content/file1.ts'
+ * '/shared/components/contracts/src/content/protocols/file2.ts'
+ * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so
+ * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime.
+ * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all
+ * root dirs were merged together.
+ * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
+ * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:
+ * '/local/src/content/protocols/file2' and try to load it - failure.
+ * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
+ * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining
+ * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.

- /**
- * Performs late-binding of a dynamic member. This performs the same function for
- * late-bound members that `declareSymbol` in binder.ts performs for early-bound
- * members.
- *
- * If a symbol is a dynamic name from a computed property, we perform an additional "late"
- * binding phase to attempt to resolve the name for the symbol from the type of the computed
- * property's expression. If the type of the expression is a string-literal, numeric-literal,
- * or unique symbol type, we can use that type as the name of the symbol.
- *
- * For example, given:
- *
- * const x = Symbol();
- *
- * interface I {
- * [x]: number;
- * }
- *
- * The binder gives the property `[x]: number` a special symbol with the name "__computed".
- * In the late-binding phase we can type-check the expression `x` and see that it has a
- * unique symbol type which we can then use as the name of the member. This allows users
- * to define custom symbols that can be used in the members of an object type.
- *
- * @param parent The containing symbol for the member.
- * @param earlySymbols The early-bound symbols of the parent.
- * @param lateSymbols The late-bound symbols of the parent.
- * @param decl The member to bind.

- // Due to how we emit async functions, we need to specialize the emit for an async method that contains a `super` reference.
- // This is due to the fact that we emit the body of an async function inside of a generator function. As generator
- // functions cannot reference `super`, we emit a helper inside of the method body, but outside of the generator. This helper
- // uses an arrow function, which is permitted to reference `super`.
- //
- // There are two primary ways we can access `super` from within an async method. The first is getting the value of a property
- // or indexed access on super, either as part of a right-hand-side expression or call expression. The second is when setting the value
- // of a property or indexed access, either as part of an assignment expression or destructuring assignment.
- //
- // The simplest case is reading a value, in which case we will emit something like the following:
- //
- // // ts
- // ...
- // async asyncMethod() {
- // let x = await super.asyncMethod();
- // return x;
- // }
- // ...
- //
- // // js
- // ...
- // asyncMethod() {
- // const _super = Object.create(null, {
- // asyncMethod: { get: () => super.asyncMethod },
- // });
- // return __awaiter(this, arguments, Promise, function *() {
- // let x = yield _super.asyncMethod.call(this);
- // return x;
- // });
- // }
- // ...
- //
- // The more complex case is when we wish to assign a value, especially as part of a destructuring assignment. As both cases
- // are legal in ES6, but also likely less frequent, we only emit setters if there is an assignment:
- //
- // // ts
- // ...
- // async asyncMethod(ar: Promise<any[]>) {
- // [super.a, super.b] = await ar;
- // }
- // ...
- //
- // // js
- // ...
- // asyncMethod(ar) {
- // const _super = Object.create(null, {
- // a: { get: () => super.a, set: (v) => super.a = v },
- // b: { get: () => super.b, set: (v) => super.b = v }
- // };
- // return __awaiter(this, arguments, Promise, function *() {
- // [_super.a, _super.b] = yield ar;
- // });
- // }
- // ...
- //
- // Creating an object that has getter and setters instead of just an accessor function is required for destructuring assignments
- // as a call expression cannot be used as the target of a destructuring assignment while a property access can.

+ //

+ // or indexed access on super, either as part of a right-hand-side expression or call expression. The second is when setting the value
+ // of a property or indexed access, either as part of an assignment expression or destructuring assignment.
+ //
+ // The simplest case is reading a value, in which case we will emit something like the following:
+ //
+ // // ts
+ // ...
+ // async asyncMethod() {
+ // let x = await super.asyncMethod();
+ // return x;

+ // let x = yield _super.asyncMethod.call(this);
+ // return x;
+ // });
+ // }
+ // ...
+ //
+ // The more complex case is when we wish to assign a value, especially as part of a destructuring assignment. As both cases
+ // are legal in ES6, but also likely less frequent, we only emit setters if there is an assignment:
+ //
+ // // ts
+ // ...
+ // async asyncMethod(ar: Promise<any[]>) {
+ // [super.a, super.b] = await ar;
+ // }
+ // ...
+ //
+ // // js
+ // ...

+ // const _super = Object.create(null, {
+ // a: { get: () => super.a, set: (v) => super.a = v },
+ // b: { get: () => super.b, set: (v) => super.b = v }
+ // };
+ // return __awaiter(this, arguments, Promise, function *() {
+ // [_super.a, _super.b] = yield ar;
+ // });
+ // }
+ // ...
+ //
+ // Creating an object that has getter and setters instead of just an accessor function is required for destructuring assignments

+ //
+ // For element access expressions (`super[x]`), we emit a generic helper that forwards the element access in both situations.

- // The __generator helper is used by down-level transformations to emulate the runtime
- // semantics of an ES2015 generator function. When called, this helper returns an
- // object that implements the Iterator protocol, in that it has `next`, `return`, and
- // `throw` methods that step through the generator when invoked.
- //
- // parameters:
- // @param thisArg The value to use as the `this` binding for the transformed generator body.
- // @param body A function that acts as the transformed generator body.
- //
- // variables:
- // _ Persistent state for the generator that is shared between the helper and the
- // generator body. The state object has the following members:
- // sent() - A method that returns or throws the current completion value.
- // label - The next point at which to resume evaluation of the generator body.
- // trys - A stack of protected regions (try/catch/finally blocks).
- // ops - A stack of pending instructions when inside of a finally block.
- // f A value indicating whether the generator is executing.
- // y An iterator to delegate for a yield*.
- // t A temporary variable that holds one of the following values (note that these
- // cases do not overlap):
- // - The completion value when resuming from a `yield` or `yield*`.
- // - The error value for a catch block.
- // - The current protected region (array of try/catch/finally/end labels).
- // - The verb (`next`, `throw`, or `return` method) to delegate to the expression
- // of a `yield*`.
- // - The result of evaluating the verb delegated to the expression of a `yield*`.
- //
- // functions:
- // verb(n) Creates a bound callback to the `step` function for opcode `n`.
- // step(op) Evaluates opcodes in a generator body until execution is suspended or
- // completed.
- //
- // The __generator helper understands a limited set of instructions:
- // 0: next(value?) - Start or resume the generator with the specified value.
- // 1: throw(error) - Resume the generator with an exception. If the generator is
- // suspended inside of one or more protected regions, evaluates
- // any intervening finally blocks between the current label and
- // the nearest catch block or function boundary. If uncaught, the
- // exception is thrown to the caller.
- // 2: return(value?) - Resume the generator as if with a return. If the generator is
- // suspended inside of one or more protected regions, evaluates any
- // intervening finally blocks.
- // 3: break(label) - Jump to the specified label. If the label is outside of the
- // current protected region, evaluates any intervening finally
- // blocks.
- // 4: yield(value?) - Yield execution to the caller with an optional value. When
- // resumed, the generator will continue at the next label.
- // 5: yield*(value) - Delegates evaluation to the supplied iterator. When
- // delegation completes, the generator will continue at the next
- // label.
- // 6: catch(error) - Handles an exception thrown from within the generator body. If
- // the current label is inside of one or more protected regions,
- // evaluates any intervening finally blocks between the current
- // label and the nearest catch block or function boundary. If
- // uncaught, the exception is thrown to the caller.
- // 7: endfinally - Ends a finally block, resuming the last instruction prior to
- // entering a finally block.
- //
