-# Instructions for Logging Issues

-

-## 1. Read the FAQ

-

-Please [read the FAQ](https://github.com/Microsoft/TypeScript/wiki/FAQ) before logging new issues, even if you think you have found a bug.

-

-Issues that ask questions answered in the FAQ will be closed without elaboration.

-

-## 2. Search for Duplicates

-

-[Search the existing issues](https://github.com/Microsoft/TypeScript/issues?utf8=%E2%9C%93&q=is%3Aissue) before logging a new one.

-

-## 3. Do you have a question?

-

-The issue tracker is for **issues**, in other words, bugs and suggestions.

-If you have a *question*, please use [Stack Overflow](http://stackoverflow.com/questions/tagged/typescript), [Gitter](https://gitter.im/Microsoft/TypeScript), your favorite search engine, or other resources.

-Due to increased traffic, we can no longer answer questions in the issue tracker.

-

-## 4. Did you find a bug?

-

-When logging a bug, please be sure to include the following:

- * What version of TypeScript you're using (run `tsc --v`)

- * If at all possible, an *isolated* way to reproduce the behavior

- * The behavior you expect to see, and the actual behavior

-

-You can try out the nightly build of TypeScript (`npm install typescript@next`) to see if the bug has already been fixed.

-

-## 5. Do you have a suggestion?

-

-We also accept suggestions in the issue tracker.

-Be sure to [check the FAQ](https://github.com/Microsoft/TypeScript/wiki/FAQ) and [search](https://github.com/Microsoft/TypeScript/issues?utf8=%E2%9C%93&q=is%3Aissue) first.

-

-In general, things we find useful when reviewing suggestions are:

-* A description of the problem you're trying to solve

-* An overview of the suggested solution

-* Examples of how the suggestion would work in various places

-  * Code examples showing e.g. "this would be an error, this wouldn't"

-  * Code examples showing the generated JavaScript (if applicable)

-* If relevant, precedent in other languages can be useful for establishing context and expected behavior

-

-# Instructions for Contributing Code

-

-## Contributing bug fixes

-

-TypeScript is currently accepting contributions in the form of bug fixes. A bug must have an issue tracking it in the issue tracker that has been approved ("Milestone == Community") by the TypeScript team. Your pull request should include a link to the bug that you are fixing. If you've submitted a PR for a bug, please post a comment in the bug to avoid duplication of effort.

-

-## Contributing features

-

-Features (things that add new or improved functionality to TypeScript) may be accepted, but will need to first be approved (marked as "Milestone == Community" by a TypeScript coordinator with the message "Approved") in the suggestion issue. Features with language design impact, or that are adequately satisfied with external tools, will not be accepted.

-

-Design changes will not be accepted at this time. If you have a design change proposal, please log a suggestion issue.

-

-## Legal

-

-You will need to complete a Contributor License Agreement (CLA). Briefly, this agreement testifies that you are granting us permission to use the submitted change according to the terms of the project's license, and that the work being submitted is under appropriate copyright.

-

-Please submit a Contributor License Agreement (CLA) before submitting a pull request. You may visit https://cla.microsoft.com to sign digitally. Alternatively, download the agreement ([Microsoft Contribution License Agreement.docx](https://www.codeplex.com/Download?ProjectName=typescript&DownloadId=822190) or [Microsoft Contribution License Agreement.pdf](https://www.codeplex.com/Download?ProjectName=typescript&DownloadId=921298)), sign, scan, and email it back to <cla@microsoft.com>. Be sure to include your github user name along with the agreement. Once we have received the signed CLA, we'll review the request. 

-

-## Housekeeping

-

-Your pull request should: 

-

-* Include a description of what your change intends to do

-* Be a child commit of a reasonably recent commit in the **master** branch 

-    * Requests need not be a single commit, but should be a linear sequence of commits (i.e. no merge commits in your PR)

-* It is desirable, but not necessary, for the tests to pass at each commit

-* Have clear commit messages 

-    * e.g. "Refactor feature", "Fix issue", "Add tests for issue"

-* Include adequate tests 

-    * At least one test should fail in the absence of your non-test code changes. If your PR does not match this criteria, please specify why

-    * Tests should include reasonable permutations of the target fix/change

-    * Include baseline changes with your change

-    * All changed code must have 100% code coverage

-* Follow the code conventions described in [Coding guidelines](https://github.com/Microsoft/TypeScript/wiki/Coding-guidelines)

-* To avoid line ending issues, set `autocrlf = input` and `whitespace = cr-at-eol` in your git configuration

-

-## Contributing `lib.d.ts` fixes

- 

-The library sources are in: [src/lib](https://github.com/Microsoft/TypeScript/tree/master/src/lib)

-

-Library files in `built/local/` are updated by running

-```Shell

-jake

-```

-

-The files in `lib/` are used to bootstrap compilation and usually do not need to be updated.

-

-#### `src/lib/dom.generated.d.ts` and `src/lib/webworker.generated.d.ts`

-

-These two files represent the DOM typings and are auto-generated. To make any modifications to them, please submit a PR to  https://github.com/Microsoft/TSJS-lib-generator

-

-## Running the Tests

-

-To run all tests, invoke the `runtests-parallel` target using jake:

-

-```Shell

-jake runtests-parallel

-```

-

-This run will all tests; to run only a specific subset of tests, use:

-

-```Shell

-jake runtests tests=<regex>

-```

-

-e.g. to run all compiler baseline tests:

-

-```Shell

-jake runtests tests=compiler

-```

-

-or to run a specific test: `tests\cases\compiler\2dArrays.ts` 

-

-```Shell

-jake runtests tests=2dArrays

-```

-

-## Debugging the tests

-

-To debug the tests, invoke the `runtests-browser` task from jake.

-You will probably only want to debug one test at a time:

-

-```Shell

-jake runtests-browser tests=2dArrays

-```

-

-You can specify which browser to use for debugging. Currently Chrome and IE are supported:

-

-```Shell

-jake runtests-browser tests=2dArrays browser=chrome

-```

-

-You can debug with VS Code or Node instead with `jake runtests debug=true`:

-

-```Shell

-jake runtests tests=2dArrays debug=true

-```

-

-## Adding a Test

-

-To add a new test case, simply place a `.ts` file in `tests\cases\compiler` containing code that exemplifies the bugfix or change you are making.

-

-These files support metadata tags in the format  `// @metaDataName: value`.

-The supported names and values are the same as those supported in the compiler itself, with the addition of the `fileName` flag.

-`fileName` tags delimit sections of a file to be used as separate compilation units.

-They are useful for tests relating to modules.

-See below for examples.

-

-**Note** that if you have a test corresponding to a specific spec compliance item, you can place it in `tests\cases\conformance` in an appropriately-named subfolder. 

-**Note** that filenames here must be distinct from all other compiler testcase names, so you may have to work a bit to find a unique name if it's something common.

-

-### Tests for multiple files

-

-When one needs to test for scenarios which require multiple files, it is useful to use the `fileName` metadata tag as such:

-

-```TypeScript

-// @fileName: file1.ts

-export function f() {

-}

-

-// @fileName: file2.ts

-import { f as g } from "file1";

-

-var x = g();

-```

-

-One can also write a project test, but it is slightly more involved.

-

-## Managing the Baselines

-

-Compiler testcases generate baselines that track the emitted `.js`, the errors produced by the compiler, and the type of each expression in the file. Additionally, some testcases opt in to baselining the source map output.

-

-When a change in the baselines is detected, the test will fail. To inspect changes vs the expected baselines, use

-

-```Shell

-jake diff

-```

-

-After verifying that the changes in the baselines are correct, run

-

-```Shell

-jake baseline-accept

-```

-

-to establish the new baselines as the desired behavior. This will change the files in `tests\baselines\reference`, which should be included as part of your commit. It's important to carefully validate changes in the baselines.

-## Building

-

-In order to build the TypeScript compiler, ensure that you have [Git](http://git-scm.com/downloads) and [Node.js](http://nodejs.org/) installed.

-

-Clone a copy of the repo:

-

-```

-git clone https://github.com/Microsoft/TypeScript.git

-```

-

-Change to the TypeScript directory:

-

-```

-cd TypeScript

-```

-

-Install Gulp tools and dev dependencies:

-

-```

-npm install -g gulp

-npm install

-```

-

-Use one of the following to build and test:

-

-```

-gulp local            # Build the compiler into built/local 

-gulp clean            # Delete the built compiler 

-gulp LKG              # Replace the last known good with the built one.

-                      # Bootstrapping step to be executed when the built compiler reaches a stable state.

-gulp tests            # Build the test infrastructure using the built compiler. 

-gulp runtests         # Run tests using the built compiler and test infrastructure. 

-                      # You can override the host or specify a test for this command. 

-                      # Use host=<hostName> or tests=<testPath>. 

-gulp runtests-browser # Runs the tests using the built run.js file. Syntax is gulp runtests. Optional

-                        parameters 'host=', 'tests=[regex], reporter=[list|spec|json|<more>]'.

-gulp baseline-accept  # This replaces the baseline test results with the results obtained from gulp runtests.

-gulp lint             # Runs tslint on the TypeScript source.

-gulp help             # List the above commands. 

-```

-

-

-## Usage

-

-```shell

-node built/local/tsc.js hello.ts

-```

-        // 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.
-        var contextFlags;
-        // Whether or not we've had a parse error since creating the last AST node.  If we have
-        // encountered an error, it will be stored on the next AST node we create.  Parse errors
-        // can be broken down into three categories:
-        //
-        // 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.

-            //   explicitly initialized. One particular case: non-captured binding

-            //    let x;

-            //

-// In addition, the illustrative intermediate representation introduces some special

-//
-//  %sent%                          - Either returns the next value sent to the generator,
-//                                    returns the result of a delegated yield, or throws
-//                                    the exception sent to the generator.
-//  %error%                         - Returns the value of the current exception in a
-//                                    catch block.
-//
-// This intermediate representation is then compiled into JavaScript syntax. The resulting
-// compilation output looks something like the following:
-//
-//  function f() {
-//      var /*locals*/;
-//      /*functions*/
-//      return __generator(function (state) {
-//          switch (state.label) {
-//              /*cases per label*/
-//          }
-//      });
-//  }
-//

-//
-//  .local NAME                   | var NAME;

-    // `throw` methods that step through the generator when invoked.
-    //
-    // parameters:
-    //  thisArg  The value to use as the `this` binding for the transformed generator body.
-    //  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.
-    //

-        // 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.
-        var contextFlags;
-        // Whether or not we've had a parse error since creating the last AST node.  If we have
-        // encountered an error, it will be stored on the next AST node we create.  Parse errors
-        // can be broken down into three categories:
-        //
-        // 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.

-            //   explicitly initialized. One particular case: non-captured binding

-            //    let x;

-            //

-// In addition, the illustrative intermediate representation introduces some special

-//
-//  %sent%                          - Either returns the next value sent to the generator,
-//                                    returns the result of a delegated yield, or throws
-//                                    the exception sent to the generator.
-//  %error%                         - Returns the value of the current exception in a
-//                                    catch block.
-//
-// This intermediate representation is then compiled into JavaScript syntax. The resulting
-// compilation output looks something like the following:
-//
-//  function f() {
-//      var /*locals*/;
-//      /*functions*/
-//      return __generator(function (state) {
-//          switch (state.label) {
-//              /*cases per label*/
-//          }
-//      });
-//  }
-//

-//
-//  .local NAME                   | var NAME;

-    // `throw` methods that step through the generator when invoked.
-    //
-    // parameters:
-    //  thisArg  The value to use as the `this` binding for the transformed generator body.
-    //  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.
-    //
