+# read-package-json
+
+This is the thing that npm uses to read package.json files.  It
+validates some stuff, and loads some default things.
+
+It keeps a cache of the files you've read, so that you don't end
+up reading the same package.json file multiple times.
+
+Note that if you just want to see what's literally in the package.json
+file, you can usually do `var data = require('some-module/package.json')`.
+
+This module is basically only needed by npm, but it's handy to see what
+npm will see when it looks at your package.
+
+## Usage
+
+```javascript
+var readJson = require('read-package-json')
+
+// readJson(filename, [logFunction=noop], [strict=false], cb)
+readJson('/path/to/package.json', console.error, false, function (er, data) {
+  if (er) {
+    console.error("There was an error reading the file")
+    return
+  }
+
+  console.error('the package data is', data)
+});
+```
+
+## readJson(file, [logFn = noop], [strict = false], cb)
+
+* `file` {String} The path to the package.json file
+* `logFn` {Function} Function to handle logging.  Defaults to a noop.
+* `strict` {Boolean} True to enforce SemVer 2.0 version strings, and
+  other strict requirements.
+* `cb` {Function} Gets called with `(er, data)`, as is The Node Way.
+
+Reads the JSON file and does the things.
+
+## `package.json` Fields
+
+See `man 5 package.json` or `npm help json`.
+
+## readJson.log
+
+By default this is a reference to the `npmlog` module.  But if that
+module can't be found, then it'll be set to just a dummy thing that does
+nothing.
+
+Replace with your own `{log,warn,error}` object for fun loggy time.
+
+## readJson.extras(file, data, cb)
+
+Run all the extra stuff relative to the file, with the parsed data.
+
+Modifies the data as it does stuff.  Calls the cb when it's done.
+
+## readJson.extraSet = [fn, fn, ...]
+
+Array of functions that are called by `extras`.  Each one receives the
+arguments `fn(file, data, cb)` and is expected to call `cb(er, data)`
+when done or when an error occurs.
+
+Order is indeterminate, so each function should be completely
+independent.
+
+Mix and match!
+
+## Other Relevant Files Besides `package.json`
+
+Some other files have an effect on the resulting data object, in the
+following ways:
+
+### `README?(.*)`
+
+If there is a `README` or `README.*` file present, then npm will attach
+a `readme` field to the data with the contents of this file.
+
+Owing to the fact that roughly 100% of existing node modules have
+Markdown README files, it will generally be assumed to be Markdown,
+regardless of the extension.  Please plan accordingly.
+
+### `server.js`
+
+If there is a `server.js` file, and there is not already a
+`scripts.start` field, then `scripts.start` will be set to `node
+server.js`.
+
+### `AUTHORS`
+
+If there is not already a `contributors` field, then the `contributors`
+field will be set to the contents of the `AUTHORS` file, split by lines,
+and parsed.
+
+### `bindings.gyp`
+
+If a bindings.gyp file exists, and there is not already a
+`scripts.install` field, then the `scripts.install` field will be set to
+`node-gyp rebuild`.
+
+### `index.js`
+
+If the json file does not exist, but there is a `index.js` file
+present instead, and that file has a package comment, then it will try
+to parse the package comment, and use that as the data instead.
+
+A package comment looks like this:
+
+```javascript
+/**package
+ * { "name": "my-bare-module"
+ * , "version": "1.2.3"
+ * , "description": "etc...." }
+ **/
+
+// or...
+
+/**package
+{ "name": "my-bare-module"
+, "version": "1.2.3"
+, "description": "etc...." }
+**/
+```
+
+The important thing is that it starts with `/**package`, and ends with
+`**/`.  If the package.json file exists, then the index.js is not
+parsed.
+
+### `{directories.man}/*.[0-9]`
+
+If there is not already a `man` field defined as an array of files or a
+single file, and
+there is a `directories.man` field defined, then that directory will
+be searched for manpages.
+
+Any valid manpages found in that directory will be assigned to the `man`
+array, and installed in the appropriate man directory at package install
+time, when installed globally on a Unix system.
+
+### `{directories.bin}/*`
+
+If there is not already a `bin` field defined as a string filename or a
+hash of `<name> : <filename>` pairs, then the `directories.bin`
+directory will be searched and all the files within it will be linked as
+executables at install time.
+
+When installing locally, npm links bins into `node_modules/.bin`, which
+is in the `PATH` environ when npm runs scripts.  When
+installing globally, they are linked into `{prefix}/bin`, which is
+presumably in the `PATH` environment variable.
+
+### `types` field
+
+If you do not have a `types` field, then it will check if a
+corresponding `*.d.ts` file exists for your package entry file and add
+it to the `package.json`.

+# json-parse-even-better-errors
+
+[`json-parse-even-better-errors`](https://github.com/npm/json-parse-even-better-errors)
+is a Node.js library for getting nicer errors out of `JSON.parse()`,
+including context and position of the parse errors.
+
+It also preserves the newline and indentation styles of the JSON data, by
+putting them in the object or array in the `Symbol.for('indent')` and
+`Symbol.for('newline')` properties.
+
+## Install
+
+`$ npm install --save json-parse-even-better-errors`
+
+## Table of Contents
+
+* [Example](#example)
+* [Features](#features)
+* [Contributing](#contributing)
+* [API](#api)
+  * [`parse`](#parse)
+
+### Example
+
+```javascript
+const parseJson = require('json-parse-even-better-errors')
+
+parseJson('"foo"') // returns the string 'foo'
+parseJson('garbage') // more useful error message
+parseJson.noExceptions('garbage') // returns undefined
+```
+
+### Features
+
+* Like JSON.parse, but the errors are better.
+* Strips a leading byte-order-mark that you sometimes get reading files.
+* Has a `noExceptions` method that returns undefined rather than throwing.
+* Attaches the newline character(s) used to the `Symbol.for('newline')`
+  property on objects and arrays.
+* Attaches the indentation character(s) used to the `Symbol.for('indent')`
+  property on objects and arrays.
+
+## Indentation
+
+To preserve indentation when the file is saved back to disk, use
+`data[Symbol.for('indent')]` as the third argument to `JSON.stringify`, and
+if you want to preserve windows `\r\n` newlines, replace the `\n` chars in
+the string with `data[Symbol.for('newline')]`.
+
+For example:
+
+```js
+const txt = await readFile('./package.json', 'utf8')
+const data = parseJsonEvenBetterErrors(txt)
+const indent = Symbol.for('indent')
+const newline = Symbol.for('newline')
+// .. do some stuff to the data ..
+const string = JSON.stringify(data, null, data[indent]) + '\n'
+const eolFixed = data[newline] === '\n' ? string
+  : string.replace(/\n/g, data[newline])
+await writeFile('./package.json', eolFixed)
+```
+
+Indentation is determined by looking at the whitespace between the initial
+`{` and `[` and the character that follows it.  If you have lots of weird
+inconsistent indentation, then it won't track that or give you any way to
+preserve it.  Whether this is a bug or a feature is debatable ;)
+
+### API
+
+#### <a name="parse"></a> `parse(txt, reviver = null, context = 20)`
+
+Works just like `JSON.parse`, but will include a bit more information when
+an error happens, and attaches a `Symbol.for('indent')` and
+`Symbol.for('newline')` on objects and arrays.  This throws a
+`JSONParseError`.
+
+#### <a name="parse"></a> `parse.noExceptions(txt, reviver = null)`
+
+Works just like `JSON.parse`, but will return `undefined` rather than
+throwing an error.
+
+#### <a name="jsonparseerror"></a> `class JSONParseError(er, text, context = 20, caller = null)`
+
+Extends the JavaScript `SyntaxError` class to parse the message and provide
+better metadata.
+
+Pass in the error thrown by the built-in `JSON.parse`, and the text being
+parsed, and it'll parse out the bits needed to be helpful.
+
+`context` defaults to 20.
+
+Set a `caller` function to trim internal implementation details out of the
+stack trace.  When calling `parseJson`, this is set to the `parseJson`
+function.  If not set, then the constructor defaults to itself, so the
+stack trace will point to the spot where you call `new JSONParseError`.
