28 +## FAQ
29 +
30 +### Why do you test for codes not in the ECMA 48 standard?
31 +
32 +Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
33 +
34 +On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

68 +## Advanced usage
69 +
70 +By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
71 +
72 +- `ansi.modifiers`
73 +- `ansi.colors`
74 +- `ansi.bgColors`
75 +
76 +
77 +###### Example
78 +
79 +```js
80 +console.log(ansi.colors.green.open);
81 +```

19 +THE SOFTWARE
1 +node-asn1 is a library for encoding and decoding ASN.1 datatypes in pure JS.
2 +Currently BER encoding is supported; at some point I'll likely have to do DER.
3 +
4 +## Usage
5 +
6 +Mostly, if you're *actually* needing to read and write ASN.1, you probably don't
7 +need this readme to explain what and why. If you have no idea what ASN.1 is,
8 +see this: ftp://ftp.rsa.com/pub/pkcs/ascii/layman.asc
9 +
10 +The source is pretty much self-explanatory, and has read/write methods for the
11 +common types out there.
12 +
13 +### Decoding
14 +
15 +The following reads an ASN.1 sequence with a boolean.
16 +
17 + var Ber = require('asn1').Ber;
18 +
19 + var reader = new Ber.Reader(new Buffer([0x30, 0x03, 0x01, 0x01, 0xff]));
20 +
21 + reader.readSequence();
22 + console.log('Sequence len: ' + reader.length);
23 + if (reader.peek() === Ber.Boolean)
24 + console.log(reader.readBoolean());
25 +
26 +### Encoding
27 +
28 +The following generates the same payload as above.
29 +
30 + var Ber = require('asn1').Ber;
31 +
32 + var writer = new Ber.Writer();
33 +
34 + writer.startSequence();
35 + writer.writeBoolean(true);
36 + writer.endSequence();
37 +
38 + console.log(writer.buffer);
39 +

1 +# assert-plus Changelog
2 +
3 +## 0.2.0
4 +
5 +- Fix `assert.object(null)` so it throws
6 +- Fix optional/arrayOf exports for non-type-of asserts
7 +- Add optiona/arrayOf exports for Stream/Date/Regex/uuid
8 +- Add basic unit test coverage
1 +# assert-plus
2 +
3 +This library is a super small wrapper over node's assert module that has two
4 +things: (1) the ability to disable assertions with the environment variable
5 +NODE\_NDEBUG, and (2) some API wrappers for argument testing. Like
6 +`assert.string(myArg, 'myArg')`. As a simple example, most of my code looks
7 +like this:
8 +
9 +```javascript
10 + var assert = require('assert-plus');
11 +
12 + function fooAccount(options, callback) {
13 + assert.object(options, 'options');
14 + assert.number(options.id, 'options.id');
15 + assert.bool(options.isManager, 'options.isManager');
16 + assert.string(options.name, 'options.name');
17 + assert.arrayOfString(options.email, 'options.email');
18 + assert.func(callback, 'callback');
19 +
20 + // Do stuff
21 + callback(null, {});
22 + }
23 +```
24 +
25 +# API
26 +
27 +All methods that *aren't* part of node's core assert API are simply assumed to
28 +take an argument, and then a string 'name' that's not a message; `AssertionError`
29 +will be thrown if the assertion fails with a message like:
30 +
31 + AssertionError: foo (string) is required
32 + at test (/home/mark/work/foo/foo.js:3:9)
33 + at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
34 + at Module._compile (module.js:446:26)
35 + at Object..js (module.js:464:10)
36 + at Module.load (module.js:353:31)
37 + at Function._load (module.js:311:12)
38 + at Array.0 (module.js:484:10)
39 + at EventEmitter._tickCallback (node.js:190:38)
40 +
41 +from:
42 +
43 +```javascript
44 + function test(foo) {
45 + assert.string(foo, 'foo');
46 + }
47 +```
48 +
49 +There you go. You can check that arrays are of a homogeneous type with `Arrayof$Type`:
50 +
51 +```javascript
52 + function test(foo) {
53 + assert.arrayOfString(foo, 'foo');
54 + }
55 +```
56 +
57 +You can assert IFF an argument is not `undefined` (i.e., an optional arg):
58 +
59 +```javascript
60 + assert.optionalString(foo, 'foo');
61 +```
62 +
63 +Lastly, you can opt-out of assertion checking altogether by setting the
64 +environment variable `NODE_NDEBUG=1`. This is pseudo-useful if you have
65 +lots of assertions, and don't want to pay `typeof ()` taxes to v8 in
66 +production. Be advised: The standard functions re-exported from `assert` are
67 +also disabled in assert-plus if NDEBUG is specified. Using them directly from
68 +the `assert` module avoids this behavior.
69 +

11 +Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install --save async`, it can also be used directly in the browser.

65 + * @method
66 + * @see [async.auto]{@link module:ControlFlow.auto}
67 + * @category Control Flow
68 + * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
69 + * the form 'func([dependencies...], callback). The object's key of a property
70 + * serves as the name of the task defined by that property, i.e. can be used
71 + * when specifying requirements for other tasks.
72 + * * The `callback` parameter is a `callback(err, result)` which must be called
73 + * when finished, passing an `error` (which can be `null`) and the result of
74 + * the function's execution. The remaining parameters name other tasks on
75 + * which the task is dependent, and the results from those tasks are the
76 + * arguments of those parameters.
77 + * @param {Function} [callback] - An optional callback which is called when all
78 + * the tasks have been completed. It receives the `err` argument if any `tasks`
79 + * pass an error to their callback, and a `results` object with any completed
80 + * task results, similar to `auto`.
81 + * @example
82 + *
83 + * // The example from `auto` can be rewritten as follows:
84 + * async.autoInject({
85 + * get_data: function(callback) {
86 + * // async code to get some data
87 + * callback(null, 'data', 'converted to array');
88 + * },
89 + * make_folder: function(callback) {
90 + * // async code to create a directory to store a file in
91 + * // this is run at the same time as getting the data
92 + * callback(null, 'folder');
93 + * },
94 + * write_file: function(get_data, make_folder, callback) {
95 + * // once there is some data and the directory exists,
96 + * // write the data to a file in the directory
97 + * callback(null, 'filename');
98 + * },
99 + * email_link: function(write_file, callback) {
100 + * // once the file is written let's email a link to it...
101 + * // write_file contains the filename returned by write_file.
102 + * callback(null, {'file':write_file, 'email':'user@example.com'});
103 + * }
104 + * }, function(err, results) {
105 + * console.log('err = ', err);
106 + * console.log('email_link = ', results.email_link);
107 + * });
108 + *
109 + * // If you are using a JS minifier that mangles parameter names, `autoInject`
110 + * // will not work with plain functions, since the parameter names will be
111 + * // collapsed to a single letter identifier. To work around this, you can
112 + * // explicitly specify the names of the parameters your task function needs
113 + * // in an array, similar to Angular.js dependency injection.
114 + *
115 + * // This still has an advantage over plain `auto`, since the results a task
116 + * // depends on are still spread into arguments.
117 + * async.autoInject({
118 + * //...
119 + * write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
120 + * callback(null, 'filename');
