9 -Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
10 -Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
11 -
12 -In addition to negotiator, it allows:
13 -
14 -- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
15 - as well as `('text/html', 'application/json')`.
16 -- Allows type shorthands such as `json`.
17 -- Returns `false` when no types match
18 -- Treats non-existent headers as `*`

20 -## Installation
21 -
22 -This is a [Node.js](https://nodejs.org/en/) module available through the
23 -[npm registry](https://www.npmjs.com/). Installation is done using the
24 -[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
25 -
26 -```sh
27 -$ npm install accepts
28 -```
29 -
30 -## API
31 -
32 -<!-- eslint-disable no-unused-vars -->
33 -
34 -```js
35 -var accepts = require('accepts')
36 -```
37 -
38 -### accepts(req)
39 -
40 -Create a new `Accepts` object for the given `req`.
41 -
42 -#### .charset(charsets)
43 -
44 -Return the first accepted charset. If nothing in `charsets` is accepted,
45 -then `false` is returned.
46 -
47 -#### .charsets()
48 -
49 -Return the charsets that the request accepts, in the order of the client's
50 -preference (most preferred first).
51 -
52 -#### .encoding(encodings)
53 -
54 -Return the first accepted encoding. If nothing in `encodings` is accepted,
55 -then `false` is returned.
56 -
57 -#### .encodings()
58 -
59 -Return the encodings that the request accepts, in the order of the client's
60 -preference (most preferred first).
61 -
62 -#### .language(languages)
63 -
64 -Return the first accepted language. If nothing in `languages` is accepted,
65 -then `false` is returned.
66 -
67 -#### .languages()
68 -
69 -Return the languages that the request accepts, in the order of the client's
70 -preference (most preferred first).
71 -
72 -#### .type(types)
73 -
74 -Return the first accepted type (and it is returned as the same text as what
75 -appears in the `types` array). If nothing in `types` is accepted, then `false`
76 -is returned.
77 -
78 -The `types` array can contain full MIME types or file extensions. Any value
79 -that is not a full MIME types is passed to `require('mime-types').lookup`.
80 -
81 -#### .types()
82 -
83 -Return the types that the request accepts, in the order of the client's
84 -preference (most preferred first).
85 -
86 -## Examples
87 -
88 -### Simple type negotiation
89 -
90 -This simple example shows how to use `accepts` to return a different typed
91 -respond body based on what the client wants to accept. The server lists it's
92 -preferences in order and will get back the best match between the client and
93 -server.
94 -
95 -```js
96 -var accepts = require('accepts')
97 -var http = require('http')
98 -
99 -function app (req, res) {
100 - var accept = accepts(req)
101 -
102 - // the order of this list is significant; should be server preferred order
103 - switch (accept.type(['json', 'html'])) {
104 - case 'json':
105 - res.setHeader('Content-Type', 'application/json')
106 - res.write('{"hello":"world!"}')
107 - break
108 - case 'html':
109 - res.setHeader('Content-Type', 'text/html')
110 - res.write('<b>hello, world!</b>')
111 - break
112 - default:
113 - // the fallback is text/plain, so no need to specify it above
114 - res.setHeader('Content-Type', 'text/plain')
115 - res.write('hello, world!')
116 - break
117 - }
118 -
119 - res.end()
120 -}
121 -
122 -http.createServer(app).listen(3000)
123 -```
124 -
125 -You can test this out with the cURL program:
126 -```sh
127 -curl -I -H'Accept: text/html' http://localhost:3000/
128 -```

12 -//
13 -// - Label consistency (no conflicts, break only to existing labels)

17 -// the parser got too confused to return anything meaningful.

2 -
3 -### Bug fixes

5 -Fix bug in tokenizing of regexp operator after a function declaration.
6 -
7 -Fix parser crash when parsing an array pattern with a hole.
8 -

12 -enable strict mode in ES7.
13 -
14 -## 3.2.0 (2016-06-07)
15 -
16 -### Bug fixes
17 -
18 -Improve handling of lack of unicode regexp support in host
19 -environment.
20 -
21 -Properly reject shorthand properties whose name is a keyword.
22 -
23 -Don't crash when the loose parser is called without options object.
24 -
25 -### New features
26 -
27 -Visitors created with `visit.make` now have their base as _prototype_,
28 -rather than copying properties into a fresh object.
29 -
30 -Make it possible to use `visit.ancestor` with a walk state.
31 -
32 -## 3.1.0 (2016-04-18)
33 -
34 -### Bug fixes
35 -
36 -Fix issue where the loose parser created invalid TemplateElement nodes
37 -for unclosed template literals.
38 -
39 -Properly tokenize the division operator directly after a function
40 -expression.
41 -
42 -Allow trailing comma in destructuring arrays.
43 -
44 -### New features
45 -
46 -The walker now allows defining handlers for `CatchClause` nodes.

48 -## 3.0.4 (2016-02-25)
49 -
50 -### Fixes
51 -
52 -Allow update expressions as left-hand-side of the ES7 exponential

67 -
68 -Support for comprehension syntax (which was dropped from the draft
69 -spec) has been removed.
70 -
71 -### Fixes
72 -
73 -`let` and `yield` are now “contextual keywords”, meaning you can
74 -mostly use them as identifiers in ES5 non-strict code.
75 -
76 -A parenthesized class or function expression after `export default` is
77 -now parsed correctly.
78 -
79 -### New features
80 -
81 -When `ecmaVersion` is set to 7, Acorn will parse the exponentiation
82 -operator (`**`).
83 -
84 -The identifier character ranges are now based on Unicode 8.0.0.
85 -
86 -Plugins can now override the `raiseRecoverable` method to override the
87 -way non-critical errors are handled.

1 -// Acorn: Loose parser
2 -//
3 -// This module provides an alternative parser (`parse_dammit`) that
4 -// exposes that same interface as `parse`, but will try to parse
5 -// anything as JavaScript, repairing syntax error the best it can.
6 -// There are circumstances in which it will raise an error and give
7 -// up, but they are very rare. The resulting AST will be a mostly
8 -// valid JavaScript AST (as per the [Mozilla parser API][api], except
9 -// that:
10 -//
11 -// - Return outside functions is allowed
12 -//
13 -// - Label consistency (no conflicts, break only to existing labels)
14 -// is not enforced.
15 -//
16 -// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
17 -// the parser got too confused to return anything meaningful.
18 -//
19 -// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
20 -//
21 -// The expected use for this is to *first* try `acorn.parse`, and only
22 -// if that fails switch to `parse_dammit`. The loose parser might
23 -// parse badly indented code incorrectly, so **don't** use it as
24 -// your default parser.
25 -//
26 -// Quite a lot of acorn.js is duplicated here. The alternative was to
27 -// add a *lot* of extra cruft to that file, making it less readable
28 -// and slower. Copying and editing the code allowed me to make
29 -// invasive changes and simplifications without creating a complicated
30 -// tangle.
