+# JavaScript extractor
+
+This directory contains the source code of the JavaScript extractor. The extractor depends on various libraries that are not currently bundled with the source code, so at present it cannot be built in isolation.
+
+The extractor consists of a parser for the latest version of ECMAScript, including a few proposed and historic extensions (see `src/com/semmle/jcorn`), classes for representing JavaScript and TypeScript ASTs (`src/com/semmle/js/ast` and `src/com/semmle/ts/ast`), and various other bits of functionality. Historically, the main entry point of the JavaScript extractor has been `com.semmle.js.extractor.Main`. However, this class is slowly being phased out in favour of `com.semmle.js.extractor.AutoBuild`, which is the entry point used by LGTM.
+
+## License
+
+Like the LGTM queries, the JavaScript extractor is licensed under [Apache License 2.0](LICENSE) by [Semmle](https://semmle.com).

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+doctrine ([doctrine](http://github.com/Constellation/doctrine)) is JSDoc parser. [![Build Status](https://secure.travis-ci.org/Constellation/doctrine.png)](http://travis-ci.org/Constellation/doctrine)
+
+It is now used by content assist system of [Eclipse Orion](http://www.eclipse.org/orion/) ([detail](http://planetorion.org/news/2012/10/orion-1-0-release/))
+
+Doctrine can be used in a web browser:
+
+    <script src="doctrine.js"></script>
+
+or in a Node.js application via the package manager:
+
+    npm install doctrine
+
+simple example:
+
+    doctrine.parse(
+        [
+            "/**",
+            " * This function comment is parsed by doctrine",
+            " * @param {{ok:String}} userName",
+            "*/"
+        ].join('\n'), { unwrap: true });
+
+and gets following information
+
+    {
+        "description": "This function comment is parsed by doctrine",
+        "tags": [
+            {
+                "title": "param",
+                "description": null,
+                "type": {
+                    "type": "RecordType",
+                    "fields": [
+                        {
+                            "type": "FieldType",
+                            "key": "ok",
+                            "value": {
+                                "type": "NameExpression",
+                                "name": "String"
+                            }
+                        }
+                    ]
+                },
+                "name": "userName"
+            }
+        ]
+    }
+
+see [demo page](http://constellation.github.com/doctrine/demo/index.html) more detail.
+
+### Options
+
+#### doctrine.parse
+We can pass options to `doctrine.parse(comment, options)`.
+```js
+{
+    unwrap: boolean,          // default: false
+    tags: [ string ] | null,  // default: null
+    recoverable: boolean,     // default: false
+    sloppy: boolean,          // default: false
+    lineNumbers: boolean      // default: false
+}
+```
+
+##### unwrap
+
+When `unwrap` is `true`, doctrine attempt to unwrap comment specific string from a provided comment text. (removes `/**`, `*/` and `*`)
+For example, `unwrap` transforms
+```
+/**
+ * @param use
+ */
+```
+to
+```
+@param use
+```
+If a provided comment has these comment specific strings, you need to specify this `unwrap` option to `true`.
+
+##### tags
+
+When `tags` array is specified, doctrine only produce tags that is specified in this array.
+For example, if you specify `[ 'param' ]`, doctrine only produces `param` tags.
+If null is specified, doctrine produces all tags that doctrine can recognize.
+
+##### recoverable
+
+When `recoverable` is `true`, doctrine becomes `recoverable` - When failing to parse jsdoc comment, doctrine recovers its state and attempt to continue parsing.
+
+##### sloppy
+
+When `sloppy` is `true`,
+```
+@param String [foo]
+```
+'s `[foo]` is interpreted as a optional parameter, not interpreted as a name of this `@param`.
+
+##### lineNumbers
+
+When `lineNumbers` is `true`, parsed tags will include a `lineNumber` property indicating the line (relative to the start of the comment block) where each tag is located in the source. So, given the following comment:
+```
+/**
+ * @param {String} foo
+ * @return {number}
+ */
+```
+The `@param` tag will have `lineNumber: 1`, and the `@return` tag will have `lineNumber: 2`.

+/**
+ * @fileoverview Wrapper for TypeScript parser, inspired by
+ *               [typescript-eslint-parser](https://github.com/eslint/typescript-eslint-parser).
+ *
+ * The wrapper can be invoked with a single argument, which is interpreted as a file name.
+ * The file is parsed and the AST dumped to stdout as described below.
+ *
+ * When run without arguments, the wrapper enters server mode, expecting JSON-encoded requests
+ * on `stdin`, one per line.
+ *
+ * Each request should have a `command` property, which should either be `parse` or `quit`.
+ *
+ * A `quit` request causes the wrapper to terminate.
+ *
+ * A `parse` request should have a `filename` property, which should be the path of a
+ * TypeScript file.
+ *
+ * In response to a `parse` request, the wrapper invokes the TypeScript parser to parse
+ * the given file, and dumps a JSON representation of the resulting AST to stdout,
+ * with the following adjustments:
+ *
+ *   - the `kind` and `operator` properties have symbolic string values instead of numeric
+ *     values (the latter change between versions of the TypeScript compiler, the former
+ *     don't);
+ *   - position information is given in terms of line/column pairs instead of offsets;
+ *   - declarations have a `declarationKind` property indicating whether they are `var`,
+ *     `let` or `const` declarations;
+ *   - `parent` pointers are omitted (since they cannot be serialised to JSON);
+ *   - tokens and comments are added to the AST root node in a `tokens` property.
