To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/) - -We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. - -To enable `estree` mode simply add the plugin in the config: -```json -{ - "plugins": [ "estree" ] -} -``` - -If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. - -Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) - -Babylon exports a new function to parse a single expression - -```js -import { parseExpression } from 'babylon'; - -const ast = parseExpression('x || y && z', options); -``` - -The returned AST will only consist of the expression.

The return value will -be an abstract syntax tree object as specified by the -[ESTree spec][estree]. - -When encountering a syntax error, the parser will raise a -`SyntaxError` object with a meaningful message. The error object will -have a `pos` property that indicates the character offset at which the -error occurred, and a `loc` object that contains a `{line, column}` -object referring to that same position. - -[estree]: https://github.com/estree/estree - -- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be - either 3, 5, or 6. This influences support for strict mode, the set - of reserved words, and support for new syntax features. Default is 5. - -- **sourceType**: Indicate the mode the code should be parsed in. Can be - either `"script"` or `"module"`. - -- **onInsertedSemicolon**: If given a callback, that callback will be - called whenever a missing semicolon is inserted by the parser. The - callback will be given the character offset of the point where the - semicolon is inserted as argument, and if `locations` is on, also a - `{line, column}` object representing this position. - -- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing - commas. - -- **allowReserved**: If `false`, using a reserved word will generate - an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher - versions. When given the value `"never"`, reserved words and - keywords can also not be used as property names (as in Internet - Explorer's old parser). - -- **allowReturnOutsideFunction**: By default, a return statement at - the top level raises an error. Set this to `true` to accept such - code. - -- **allowImportExportEverywhere**: By default, `import` and `export` - declarations can only appear at a program's top level. Setting this - option to `true` allows them anywhere where a statement is allowed. - -- **allowHashBang**: When this is enabled (off by default), if the - code starts with the characters `#!` (as in a shellscript), the - first line will be treated as a comment. - -- **locations**: When `true`, each node has a `loc` object attached - with `start` and `end` subobjects, each of which contains the - one-based line and zero-based column numbers in `{line, column}` - form. Default is `false`. - -- **onToken**: If a function is passed for this option, each found - token will be passed in same format as tokens returned from - `tokenizer().getToken()`. - - If array is passed, each found token is pushed to it. - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **onComment**: If a function is passed for this option, whenever a - comment is encountered the function will be called with the - following parameters: - - - `block`: `true` if the comment is a block comment, false if it - is a line comment. - - `text`: The content of the comment. - - `start`: Character offset of the start of the comment. - - `end`: Character offset of the end of the comment. - - When the `locations` options is on, the `{line, column}` locations - of the comment’s start and end are passed as two additional - parameters. - - If array is passed for this option, each found comment is pushed - to it as object in Esprima format: - - ```javascript - { - "type": "Line" | "Block", - "value": "comment text", - "start": Number, - "end": Number, - // If `locations` option is on: - "loc": { - "start": {line: Number, column: Number} - "end": {line: Number, column: Number} - }, - // If `ranges` option is on: - "range": [Number, Number] - } - ``` - - Note that you are not allowed to call the parser from the - callback—that will corrupt its internal state. - -- **ranges**: Nodes have their start and end characters offsets - recorded in `start` and `end` properties (directly on the node, - rather than the `loc` object, which holds line/column data. To also - add a [semi-standardized][range] `range` property holding a - `[start, end]` array with the same numbers, set the `ranges` option - to `true`. - -- **program**: It is possible to parse multiple files into a single - AST by passing the tree produced by parsing the first file as the - `program` option in subsequent parses. This will add the toplevel - forms of the parsed file to the "Program" (top) node of an existing - parse tree. - -- **sourceFile**: When the `locations` option is `true`, you can pass - this option to add a `source` attribute in every node’s `loc` - object. Note that the contents of this option are not examined or - processed in any way; you are free to use whatever format you - choose. - -- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property - will be added directly to the nodes, rather than the `loc` object. - -- **preserveParens**: If this option is `true`, parenthesized expressions - are represented by (non-standard) `ParenthesizedExpression` nodes - that have a single `expression` property containing the expression - inside parentheses. - -[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678 - -**parseExpressionAt**`(input, offset, options)` will parse a single -expression in a string, and return its AST. It will not complain if -there is more of the string left after the expression. - -**getLineInfo**`(input, offset)` can be used to get a `{line, -column}` object for a given program string and character offset. - -**tokenizer**`(input, options)` returns an object with a `getToken` -method that can be called repeatedly to get the next token, a `{start, -end, type, value}` object (with added `loc` property when the -`locations` option is enabled and `range` property when the `ranges` -option is enabled). When the token's type is `tokTypes.eof`, you -should stop calling the method, since it will keep returning that same -token forever. - -In ES6 environment, returned result can be used as any other -protocol-compliant iterable: - -```javascript -for (let token of acorn.tokenizer(str)) { - // iterate over the tokens -} - -// transform code to array of tokens: -var tokens = [...acorn.tokenizer(str)]; -``` - -**tokTypes** holds an object mapping names to the token type objects -that end up in the `type` properties of tokens. - -#### Note on using with [Escodegen][escodegen] - -Escodegen supports generating comments from AST, attached in -Esprima-specific format. In order to simulate same format in -Acorn, consider following example: - -```javascript -var comments = [], tokens = []; - -var ast = acorn.parse('var x = 42; // answer', { - // collect ranges for each node - ranges: true, - // collect comments in Esprima's format - onComment: comments, - // collect token ranges - onToken: tokens -}); - -// attach comments using collected information -escodegen.attachComments(ast, comments, tokens); - -// generate code -console.log(escodegen.generate(ast, {comment: true})); -// > 'var x = 42; // answer' -``` - -[escodegen]: https://github.com/estools/escodegen - -### dist/acorn_loose.js ### - -This file implements an error-tolerant parser. It exposes a single -function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`. - -**parse_dammit**`(input, options)` takes the same arguments and -returns the same syntax tree as the `parse` function in `acorn.js`, -but never raises an error, and will do its best to parse syntactically -invalid code in as meaningful a way as it can. It'll insert identifier -nodes with name `"✖"` as placeholders in places where it can't make -sense of the input. Depends on `acorn.js`, because it uses the same -tokenizer. - -### dist/walk.js ### - -Implements an abstract syntax tree walker. Will store its interface in -`acorn.walk` when loaded without a module system. - -**simple**`(node, visitors, base, state)` does a 'simple' walk over -a tree. `node` should be the AST node to walk, and `visitors` an -object with properties whose names correspond to node types in the -[ESTree spec][estree]. The properties should contain functions -that will be called with the node object and, if applicable the state -at that point. The last two arguments are optional. `base` is a walker -algorithm, and `state` is a start state. The default walker will -simply visit all statements and expressions and not produce a -meaningful state. (An example of a use of state is to track scope at -each point in the tree.) - -**ancestor**`(node, visitors, base, state)` does a 'simple' walk over -a tree, building up an array of ancestor nodes (including the current node) -and passing the array to callbacks in the `state` parameter. - -**recursive**`(node, state, functions, base)` does a 'recursive' -walk, where the walker functions are responsible for continuing the -walk on the child nodes of their target node. `state` is the start -state, and `functions` should contain an object that maps node types -to walker functions. Such functions are called with `(node, state, c)` -arguments, and can cause the walk to continue on a sub-node by calling -the `c` argument on it with `(node, state)` arguments. The optional -`base` argument provides the fallback walker functions for node types -that aren't handled in the `functions` object. If not given, the -default walkers will be used. - -**make**`(functions, base)` builds a new walker object by using the -walker functions in `functions` and filling in the missing ones by -taking defaults from `base`. - -**findNodeAt**`(node, start, end, test, base, state)` tries to -locate a node in a tree at the given start and/or end offsets, which -satisfies the predicate `test`. `start` and `end` can be either `null` -(as wildcard) or a number. `test` may be a string (indicating a node -type) or a function that takes `(nodeType, node)` arguments and -returns a boolean indicating whether this node is interesting. `base` -and `state` are optional, and can be used to specify a custom walker. -Nodes are tested from inner to outer, so if two nodes match the -boundaries, the inner one will be preferred. - -**findNodeAround**`(node, pos, test, base, state)` is a lot like -`findNodeAt`, but will match any node that exists 'around' (spanning) -the given position. - -**findNodeAfter**`(node, pos, test, base, state)` is similar to -`findNodeAround`, but will match all nodes *after* the given position -(testing outer nodes before inner nodes). - -## Command line interface - -The `bin/acorn` utility can be used to parse a file from the command -line. It accepts as arguments its input file and the following -options: - -- `--ecma3|--ecma5|--ecma6`: Sets the ECMAScript version to parse. Default is - version 5. - -- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise. - -- `--locations`: Attaches a "loc" object to each node with "start" and - "end" subobjects, each of which contains the one-based line and - zero-based column numbers in `{line, column}` form. - -- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment. - -- `--compact`: No whitespace is used in the AST output. - -- `--silent`: Do not output the AST, just return the exit status. - -- `--help`: Print the usage information and quit. - -The utility spits out the syntax tree as JSON data. - -## Build system - -Acorn is written in ECMAScript 6, as a set of small modules, in the -project's `src` directory, and compiled down to bigger ECMAScript 3 -files in `dist` using [Browserify](http://browserify.org) and -[Babel](http://babeljs.io/). If you are already using Babel, you can -consider including the modules directly. - -The command-line test runner (`npm test`) uses the ES6 modules. The -browser-based test page (`test/index.html`) uses the compiled modules. -The `bin/build-acorn.js` script builds the latter from the former. - -If you are working on Acorn, you'll probably want to try the code out -directly, without an intermediate build step. In your scripts, you can -register the Babel require shim like this: - - require("babel-core/register") - -That will allow you to directly `require` the ES6 modules. - -## Plugins - -Acorn is designed support allow plugins which, within reasonable -bounds, redefine the way the parser works. Plugins can add new token -types and new tokenizer contexts (if necessary), and extend methods in -the parser object. This is not a clean, elegant API—using it requires -an understanding of Acorn's internals, and plugins are likely to break -whenever those internals are significantly changed. But still, it is -_possible_, in this way, to create parsers for JavaScript dialects -without forking all of Acorn. And in principle it is even possible to -combine such plugins, so that if you have, for example, a plugin for -parsing types and a plugin for parsing JSX-style XML literals, you -could load them both and parse code with both JSX tags and types. - -A plugin should register itself by adding a property to -`acorn.plugins`, which holds a function. Calling `acorn.parse`, a -`plugins` option can be passed, holding an object mapping plugin names -to configuration values (or just `true` for plugins that don't take -options). After the parser object has been created, the initialization -functions for the chosen plugins are called with `(parser, -configValue)` arguments. They are expected to use the `parser.extend` -method to extend parser methods. For example, the `readToken` method -could be extended like this: - -```javascript -parser.extend("readToken", function(nextMethod) { - return function(code) { - console.log("Reading a token!") - return nextMethod.call(this, code) - } -}) -``` - -The `nextMethod` argument passed to `extend`'s second argument is the -previous value of this method, and should usually be called through to -whenever the extended method does not handle the call itself. - -Similarly, the loose parser allows plugins to register themselves via -`acorn.pluginsLoose`. The extension mechanism is the same as for the -normal parser: - -```javascript -looseParser.extend("readToken", function(nextMethod) { - return function() { - console.log("Reading a token in the loose parser!") - return nextMethod.call(this) - } -}) -``` - -There is a proof-of-concept JSX plugin in the [`acorn-jsx`](https://github.com/RReverser/acorn-jsx) project. diff --git a/node_modules/acorn/bin/acorn b/node_modules/acorn/bin/acorn deleted file mode 100755 index db07909..0000000 --- a/node_modules/acorn/bin/acorn +++ /dev/null @@ -1,71 +0,0 @@ -#!/usr/bin/env node -"use strict"; - -function _interopRequireWildcard(obj) { if (obj && obj.__esModule) { return obj; } else { var newObj = {}; if (obj != null) { for (var key in obj) { if (Object.prototype.hasOwnProperty.call(obj, key)) newObj[key] = obj[key]; } } newObj["default"] = obj; return newObj; } } - -var _path = require("path"); - -var _fs = require("fs"); - -var _distAcornJs = require("../dist/acorn.js"); - -var acorn = _interopRequireWildcard(_distAcornJs); - -var infile = undefined, - forceFile = undefined, - silent = false, - compact = false, - tokenize = false; -var options = {}; - -function help(status) { - var print = status == 0 ?

The parsing can be aborted by throwing an error. - -### bodyParser.urlencoded([options]) - -Returns middleware that only parses `urlencoded` bodies and only looks at -requests where the `Content-Type` header matches the `type` option. This -parser accepts only UTF-8 encoding of the body and supports automatic -inflation of `gzip` and `deflate` encodings. - -A new `body` object containing the parsed data is populated on the `request` -object after the middleware (i.e. `req.body`). This object will contain -key-value pairs, where the value can be a string or array (when `extended` is -`false`), or any type (when `extended` is `true`). - -#### Options - -The `urlencoded` function takes an optional `options` object that may contain -any of the following keys: - -##### extended - -The `extended` option allows to choose between parsing the URL-encoded data -with the `querystring` library (when `false`) or the `qs` library (when -`true`). The "extended" syntax allows for rich objects and arrays to be -encoded into the URL-encoded format, allowing for a JSON-like experience -with URL-encoded. For more information, please -[see the qs library](https://www.npmjs.org/package/qs#readme). - -Defaults to `true`, but using the default has been deprecated. Please -research into the difference between `qs` and `querystring` and choose the -appropriate setting. - -##### inflate - -When set to `true`, then deflated (compressed) bodies will be inflated; when -`false`, deflated bodies are rejected. Defaults to `true`. - -##### limit - -Controls the maximum request body size. If this is a number, then the value -specifies the number of bytes; if it is a string, the value is passed to the -[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults -to `'100kb'`. - -##### parameterLimit - -The `parameterLimit` option controls the maximum number of parameters that -are allowed in the URL-encoded data. If a request contains more parameters -than this value, a 413 will be returned to the client. Defaults to `1000`. - -##### type - -The `type` option is used to determine what media type the middleware will -parse. This option can be a string, array of strings, or a function. If not -a function, `type` option is passed directly to the -[type-is](https://www.npmjs.org/package/type-is#readme) library and this can -be an extension name (like `urlencoded`), a mime type (like -`application/x-www-form-urlencoded`), or a mime type with a wildcard (like -`*/x-www-form-urlencoded`). If a function, the `type` option is called as -`fn(req)` and the request is parsed if it returns a truthy value. Defaults -to `application/x-www-form-urlencoded`. - -##### verify - -The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`, -where `buf` is a `Buffer` of the raw request body and `encoding` is the -encoding of the request. The parsing can be aborted by throwing an error. - -## Errors - -The middlewares provided by this module create errors depending on the error -condition during parsing. The errors will typically have a `status`/`statusCode` -property that contains the suggested HTTP response code, an `expose` property -to determine if the `message` property should be displayed to the client, a -`type` property to determine the type of error without matching against the -`message`, and a `body` property containing the read body, if available. - -The following are the common errors emitted, though any error can come through -for various reasons. - -### content encoding unsupported - -This error will occur when the request had a `Content-Encoding` header that -contained an encoding but the "inflation" option was set to `false`. The -`status` property is set to `415`, the `type` property is set to -`'encoding.unsupported'`, and the `charset` property will be set to the -encoding that is unsupported. - -### request aborted - -This error will occur when the request is aborted by the client before reading -the body has finished. The `received` property will be set to the number of -bytes received before the request was aborted and the `expected` property is -set to the number of expected bytes. The `status` property is set to `400` -and `type` property is set to `'request.aborted'`. - -### request entity too large - -This error will occur when the request body's size is larger than the "limit" -option. The `limit` property will be set to the byte limit and the `length` -property will be set to the request body's length. The `status` property is -set to `413` and the `type` property is set to `'entity.too.large'`. - -### request size did not match content length - -This error will occur when the request's length did not match the length from -the `Content-Length` header. This typically occurs when the request is malformed, -typically when the `Content-Length` header was calculated based on characters -instead of bytes. The `status` property is set to `400` and the `type` property -is set to `'request.size.invalid'`. - -### stream encoding should not be set - -This error will occur when something called the `req.setEncoding` method prior -to this middleware. This module operates directly on bytes only and you cannot -call `req.setEncoding` when using this module. The `status` property is set to -`500` and the `type` property is set to `'stream.encoding.set'`. - -### too many parameters - -This error will occur when the content of the request exceeds the configured -`parameterLimit` for the `urlencoded` parser. The `status` property is set to -`413` and the `type` property is set to `'parameters.too.many'`. - -### unsupported charset "BOGUS" - -This error will occur when the request had a charset parameter in the -`Content-Type` header, but the `iconv-lite` module does not support it OR the -parser does not support it. The charset is contained in the message as well -as in the `charset` property. The `status` property is set to `415`, the -`type` property is set to `'charset.unsupported'`, and the `charset` property -is set to the charset that is unsupported. - -### unsupported content encoding "bogus" - -This error will occur when the request had a `Content-Encoding` header that -contained an unsupported encoding. The encoding is contained in the message -as well as in the `encoding` property. The `status` property is set to `415`, -the `type` property is set to `'encoding.unsupported'`, and the `encoding` -property is set to the encoding that is unsupported. - -## Examples - -### Express/Connect top-level generic - -This example demonstrates adding a generic JSON and URL-encoded parser as a -top-level middleware, which will parse the bodies of all incoming requests. -This is the simplest setup. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// parse application/x-www-form-urlencoded -app.use(bodyParser.urlencoded({ extended: false })) - -// parse application/json -app.use(bodyParser.json()) - -app.use(function (req, res) { - res.setHeader('Content-Type', 'text/plain') - res.write('you posted:\n') - res.end(JSON.stringify(req.body, null, 2)) -}) -``` - -### Express route-specific - -This example demonstrates adding body parsers specifically to the routes that -need them. In general, this is the most recommended way to use body-parser with -Express. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// create application/json parser -var jsonParser = bodyParser.json() - -// create application/x-www-form-urlencoded parser -var urlencodedParser = bodyParser.urlencoded({ extended: false }) - -// POST /login gets urlencoded bodies -app.post('/login', urlencodedParser, function (req, res) { - if (!req.body) return res.sendStatus(400) - res.send('welcome, ' + req.body.username) -}) - -// POST /api/users gets JSON bodies -app.post('/api/users', jsonParser, function (req, res) { - if (!req.body) return res.sendStatus(400) - // create user in req.body -}) -``` - -### Change accepted type for parsers - -All the parsers accept a `type` option which allows you to change the -`Content-Type` that the middleware will parse. - -```js -var express = require('express') -var bodyParser = require('body-parser') - -var app = express() - -// parse various different custom JSON types as JSON -app.use(bodyParser.json({ type: 'application/*+json' })) - -// parse some custom thing into a Buffer -app.use(bodyParser.raw({ type: 'application/vnd.custom-type' })) - -// parse an HTML body into a string -app.use(bodyParser.text({ type: 'text/html' })) -``` - -## License - -[MIT](LICENSE) - -[npm-image]: https://img.shields.io/npm/v/body-parser.svg -[npm-url]: https://npmjs.org/package/body-parser -[travis-image]: https://img.shields.io/travis/expressjs/body-parser/master.svg -[travis-url]: https://travis-ci.org/expressjs/body-parser -[coveralls-image]: https://img.shields.io/coveralls/expressjs/body-parser/master.svg -[coveralls-url]: https://coveralls.io/r/expressjs/body-parser?branch=master -[downloads-image]: https://img.shields.io/npm/dm/body-parser.svg -[downloads-url]: https://npmjs.org/package/body-parser diff --git a/node_modules/body-parser/index.js b/node_modules/body-parser/index.js deleted file mode 100644 index 93c3a1f..0000000 --- a/node_modules/body-parser/index.js +++ /dev/null @@ -1,157 +0,0 @@ -/*! -

This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. - -Example _app.js_: - -```js -var debug = require('debug')('http') - , http = require('http') - , name = 'My App'; - -// fake app - -debug('booting %s', name); - -http.createServer(function(req, res){ - debug(req.method + ' ' + req.url); - res.end('hello\n'); -}).listen(3000, function(){ - debug('listening'); -}); - -// fake worker of some kind - -require('./worker'); -``` - -Example _worker.js_: - -```js -var debug = require('debug')('worker'); - -setInterval(function(){ - debug('doing some work'); -}, 1000); -``` - - The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: - - ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) - - ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) - -#### Windows note - - On Windows the environment variable is set using the `set` command. - - ```cmd - set DEBUG=*,-not_this - ``` - - Note that PowerShell uses different syntax to set environment variables. - - ```cmd - $env:DEBUG = "*,-not_this" - ``` - -Then, run the program to be debugged as usual. - -## Millisecond diff - - When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. - - ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) - - When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: - - ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) - -## Conventions - - If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". - -## Wildcards - - The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. - - You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". - -## Environment Variables - - When running through Node.js, you can set a few environment variables that will - change the behavior of the debug logging: - -| Name | Purpose | -|-----------|-------------------------------------------------| -| `DEBUG` | Enables/disables specific debugging namespaces. | -| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | -| `DEBUG_DEPTH` | Object inspection depth. | -| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | - - - __Note:__ The environment variables beginning with `DEBUG_` end up being - converted into an Options object that gets used with `%o`/`%O` formatters. - See the Node.js documentation for - [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) - for the complete list. - -## Formatters - - - Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: - -| Formatter | Representation | -|-----------|----------------| -| `%O` | Pretty-print an Object on multiple lines. | -| `%o` | Pretty-print an Object all on a single line. | -| `%s` | String. | -| `%d` | Number (both integer and float). | -| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | -| `%%` | Single percent sign ('%'). This does not consume an argument. | - -### Custom formatters - - You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: - -```js -const createDebug = require('debug') -createDebug.formatters.h = (v) => { - return v.toString('hex') -} - -// …elsewhere -const debug = createDebug('foo') -debug('this is hex: %h', new Buffer('hello world')) -// foo this is hex: 68656c6c6f20776f726c6421 +0ms -``` - -## Browser support - You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), - or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), - if you don't want to build it yourself. - - Debug's enable state is currently persisted by `localStorage`. - Consider the situation shown below where you have `worker:a` and `worker:b`, - and wish to debug both. You can enable this using `localStorage.debug`: - -```js -localStorage.debug = 'worker:*' -``` - -And then refresh the page. - -```js -a = debug('worker:a'); -b = debug('worker:b'); - -setInterval(function(){ - a('doing some work'); -}, 1000); - -setInterval(function(){ - b('doing some work'); -}, 1200); -``` - -#### Web Inspector Colors - - Colors are also enabled on "Web Inspectors" that understand the `%c` formatting - option.

Installation is done using the -[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): - -```bash -$ npm install bytes -``` - -## Usage - -```js -var bytes = require('bytes'); -``` - -#### bytes.format(number value, [options]): string｜null - -Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is - rounded. - -**Arguments** - -| Name | Type | Description | -|---------|----------|--------------------| -| value | `number` | Value in bytes | -| options | `Object` | Conversion options | - -**Options** - -| Property | Type | Description | -|-------------------|--------|-----------------------------------------------------------------------------------------| -| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. | -| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` | -| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `.`... Default value to `''`. | -| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). | -| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. | - -**Returns** - -| Name | Type | Description | -|---------|------------------|-------------------------------------------------| -| results | `string`｜`null` | Return null upon error. String value otherwise. | - -**Example** - -```js -bytes(1024); -// output: '1KB' - -bytes(1000); -// output: '1000B' - -bytes(1000, {thousandsSeparator: ' '}); -// output: '1 000B' - -bytes(1024 * 1.7, {decimalPlaces: 0}); -// output: '2KB' - -bytes(1024, {unitSeparator: ' '}); -// output: '1 KB' - -``` - -#### bytes.parse(string｜number value): number｜null - -Parse the string value into an integer in bytes. If no unit is given, or `value` -is a number, it is assumed the value is in bytes. - -Supported units and abbreviations are as follows and are case-insensitive: - - * `b` for bytes - * `kb` for kilobytes - * `mb` for megabytes - * `gb` for gigabytes - * `tb` for terabytes - -The units are in powers of two, not ten. This means 1kb = 1024b according to this parser. - -**Arguments** - -| Name | Type | Description | -|---------------|--------|--------------------| -| value | `string`｜`number` | String to parse, or number in bytes. | - -**Returns** - -| Name | Type | Description | -|---------|-------------|-------------------------| -| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. | - -**Example** - -```js -bytes('1KB'); -// output: 1024 - -bytes('1024'); -// output: 1024 - -bytes(1024); -// output: 1024 -``` - -## License - -[MIT](LICENSE) - -[downloads-image]: https://img.shields.io/npm/dm/bytes.svg -[downloads-url]: https://npmjs.org/package/bytes -[npm-image]: https://img.shields.io/npm/v/bytes.svg -[npm-url]: https://npmjs.org/package/bytes -[travis-image]: https://img.shields.io/travis/visionmedia/bytes.js/master.svg -[travis-url]: https://travis-ci.org/visionmedia/bytes.js -[coveralls-image]: https://img.shields.io/coveralls/visionmedia/bytes.js/master.svg -[coveralls-url]: https://coveralls.io/r/visionmedia/bytes.js?branch=master diff --git a/node_modules/bytes/index.js b/node_modules/bytes/index.js deleted file mode 100644 index 1e39afd..0000000 --- a/node_modules/bytes/index.js +++ /dev/null @@ -1,159 +0,0 @@ -/*! - * bytes - * Copyright(c) 2012-2014 TJ Holowaychuk - * Copyright(c) 2015 Jed Watson - * MIT Licensed - */ - -'use strict'; - -/** - * Module exports. - * @public - */ - -module.exports = bytes; -module.exports.format = format; -module.exports.parse = parse; - -/** - * Module variables. - * @private - */ - -var formatThousandsRegExp = /\B(?=(\d{3})+(?!\d))/g; - -var formatDecimalsRegExp = /(?:\.0*|(\.[^0]+)0+)$/; - -var map = { - b: 1, - kb: 1 << 10, - mb: 1 << 20, - gb: 1 << 30, - tb: ((1 << 30) * 1024) -}; - -var parseRegExp = /^((-|\+)?(\d+(?:\.\d+)?)) *(kb|mb|gb|tb)$/i; - -/** - * Convert the given value in bytes into a string or parse to string to an integer in bytes. - * - * @param {string|number} value - * @param {{ - * case: [string], - * decimalPlaces: [number] - * fixedDecimals: [boolean] - * thousandsSeparator: [string] - * unitSeparator: [string] - * }} [options] bytes options. - * - * @returns {string|number|null} - */ - -function bytes(value, options) { - if (typeof value === 'string') { - return parse(value); - } - - if (typeof value === 'number') { - return format(value, options); - } - - return null; -} - -/** - * Format the given value in bytes into a string. - * - * If the value is negative, it is kept as such.

- -```js -var CleanCSS = require('clean-css'); -var source = 'a{font-weight:bold;}'; -var minified = new CleanCSS().minify(source).styles; -``` - -CleanCSS constructor accepts a hash as a parameter, i.e., -`new CleanCSS(options)` with the following options available: - -* `advanced` - set to false to disable advanced optimizations - selector & property merging, reduction, etc. -* `aggressiveMerging` - set to false to disable aggressive merging of properties. -* `benchmark` - turns on benchmarking mode measuring time spent on cleaning up (run `npm run bench` to see example) -* `compatibility` - enables compatibility mode, see [below for more examples](#how-to-set-a-compatibility-mode) -* `debug` - set to true to get minification statistics under `stats` property (see `test/custom-test.js` for examples) -* `inliner` - a hash of options for `@import` inliner, see [test/protocol-imports-test.js](https://github.com/jakubpawlowicz/clean-css/blob/master/test/protocol-imports-test.js#L372) for examples, or [this comment](https://github.com/jakubpawlowicz/clean-css/issues/612#issuecomment-119594185) for a proxy use case. -* `keepBreaks` - whether to keep line breaks (default is false) -* `keepSpecialComments` - `*` for keeping all (default), `1` for keeping first one only, `0` for removing all -* `mediaMerging` - whether to merge `@media` at-rules (default is true) -* `processImport` - whether to process `@import` rules -* `processImportFrom` - a list of `@import` rules, can be `['all']` (default), `['local']`, `['remote']`, or a blacklisted path e.g. `['!fonts.googleapis.com']` -* `rebase` - set to false to skip URL rebasing -* `relativeTo` - path to **resolve** relative `@import` rules and URLs -* `restructuring` - set to false to disable restructuring in advanced optimizations -* `root` - path to **resolve** absolute `@import` rules and **rebase** relative URLs -* `roundingPrecision` - rounding precision; defaults to `2`; `-1` disables rounding -* `semanticMerging` - set to true to enable semantic merging mode which assumes BEM-like content (default is false as it's highly likely this will break your stylesheets - **use with caution**!) -* `shorthandCompacting` - set to false to skip shorthand compacting (default is true unless sourceMap is set when it's false) -* `sourceMap` - exposes source map under `sourceMap` property, e.g. `new CleanCSS().minify(source).sourceMap` (default is false) - If input styles are a product of CSS preprocessor (Less, Sass) an input source map can be passed as a string. -* `sourceMapInlineSources` - set to true to inline sources inside a source map's `sourcesContent` field (defaults to false) - It is also required to process inlined sources from input source maps. -* `target` - path to a folder or an output file to which **rebase** all URLs - -The output of `minify` method (or the 2nd argument to passed callback) is a hash containing the following fields: - -* `styles` - optimized output CSS as a string -* `sourceMap` - output source map (if requested with `sourceMap` option) -* `errors` - a list of errors raised -* `warnings` - a list of warnings raised -* `stats` - a hash of statistic information (if requested with `debug` option): - * `originalSize` - original content size (after import inlining) - * `minifiedSize` - optimized content size - * `timeSpent` - time spent on optimizations - * `efficiency` - a ratio of output size to input size (e.g. 25% if content was reduced from 100 bytes to 75 bytes) - -#### How to make sure remote `@import`s are processed correctly? - -In order to inline remote `@import` statements you need to provide a callback to minify method, e.g.: - -```js -var CleanCSS = require('clean-css'); -var source = '@import url(http://path/to/remote/styles);'; -new CleanCSS().minify(source, function (errors, minified) { - // minified.styles -}); -``` - -This is due to a fact, that, while local files can be read synchronously, remote resources can only be processed asynchronously. -If you don't provide a callback, then remote `@import`s will be left intact. - -### How to use clean-css with build tools?

- -First clone the source, then run: - -* `npm run bench` for clean-css benchmarks (see [test/bench.js](https://github.com/jakubpawlowicz/clean-css/blob/master/test/bench.js) for details) -* `npm run browserify` to create the browser-ready clean-css version -* `npm run check` to check JS sources with [JSHint](https://github.com/jshint/jshint/) -* `npm test` for the test suite - -## How to contribute to clean-css? - -See [CONTRIBUTING.md](https://github.com/jakubpawlowicz/clean-css/blob/master/CONTRIBUTING.md). - -## Tips & Tricks - -### How to preserve a comment block? - -Use the `/*!` notation instead of the standard one `/*`: - -```css -/*! - Important comments included in minified output. -*/ -``` - -### How to rebase relative image URLs? - -Clean-css will handle it automatically for you (since version 1.1) in the following cases: - -* When using the CLI: - 1. Use an output path via `-o`/`--output` to rebase URLs as relative to the output file. - 2. Use a root path via `-r`/`--root` to rebase URLs as absolute from the given root path. - 3. If you specify both then `-r`/`--root` takes precendence. -* When using clean-css as a library: - 1. Use a combination of `relativeTo` and `target` options for relative rebase (same as 1 in CLI). - 2. Use a combination of `relativeTo` and `root` options for absolute rebase (same as 2 in CLI). - 3. `root` takes precendence over `target` as in CLI. - -### How to generate source maps? - -Source maps are supported since version 3.0. - -Additionally to mapping original CSS files, clean-css also supports input source maps, so minified styles can be mapped into their [Less](http://lesscss.org/) or [Sass](http://sass-lang.com/) sources directly. - -Source maps are generated using [source-map](https://github.com/mozilla/source-map/) module from Mozilla. - -#### Using CLI - -To generate a source map, use `--source-map` switch, e.g.: - -``` -cleancss --source-map --output styles.min.css styles.css -``` - -Name of the output file is required, so a map file, named by adding `.map` suffix to output file name, can be created (styles.min.css.map in this case). - -#### Using API - -To generate a source map, use `sourceMap: true` option, e.g.: - -```js -new CleanCSS({ sourceMap: true, target: pathToOutputDirectory }) - .minify(source, function (minified) { - // access minified.sourceMap for SourceMapGenerator object - // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details - // see https://github.com/jakubpawlowicz/clean-css/blob/master/bin/cleancss#L114 on how it's used in clean-css' CLI -}); -``` - -Using API you can also pass an input source map directly: - -```js -new CleanCSS({ sourceMap: inputSourceMapAsString, target: pathToOutputDirectory }) - .minify(source, function (minified) { - // access minified.sourceMap to access SourceMapGenerator object - // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details - // see https://github.com/jakubpawlowicz/clean-css/blob/master/bin/cleancss#L114 on how it's used in clean-css' CLI -}); -``` - -Or even multiple input source maps at once (available since version 3.1): - -```js -new CleanCSS({ sourceMap: true, target: pathToOutputDirectory }).minify({ - 'path/to/source/1': { - styles: '...styles...', - sourceMap: '...source-map...' - }, - 'path/to/source/2': { - styles: '...styles...', - sourceMap: '...source-map...' - } -}, function (minified) { - // access minified.sourceMap as above -}); -``` - -### How to minify multiple files with API? - -#### Passing an array - -```js -new CleanCSS().minify(['path/to/file/one', 'path/to/file/two']); -``` - -#### Passing a hash - -```js -new CleanCSS().minify({ - 'path/to/file/one': { - styles: 'contents of file one' - }, - 'path/to/file/two': { - styles: 'contents of file two' - } -}); -``` - -### How to set a compatibility mode? - -Compatibility settings are controlled by `--compatibility` switch (CLI) and `compatibility` option (library mode). - -In both modes the following values are allowed: - -* `'ie7'` - Internet Explorer 7 compatibility mode -* `'ie8'` - Internet Explorer 8 compatibility mode -* `''` or `'*'` (default) - Internet Explorer 9+ compatibility mode - -Since clean-css 3 a fine grained control is available over -[those settings](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/utils/compatibility.js), -with the following options available: - -* `'[+-]colors.opacity'` - - turn on (+) / off (-) `rgba()` / `hsla()` declarations removal -* `'[+-]properties.backgroundClipMerging'` - turn on / off background-clip merging into shorthand -* `'[+-]properties.backgroundOriginMerging'` - turn on / off background-origin merging into shorthand -* `'[+-]properties.backgroundSizeMerging'` - turn on / off background-size merging into shorthand -* `'[+-]properties.colors'` - turn on / off any color optimizations -* `'[+-]properties.ieBangHack'` - turn on / off IE bang hack removal -* `'[+-]properties.iePrefixHack'` - turn on / off IE prefix hack removal -* `'[+-]properties.ieSuffixHack'` - turn on / off IE suffix hack removal -* `'[+-]properties.merging'` - turn on / off property merging based on understandability -* `'[+-]properties.spaceAfterClosingBrace'` - turn on / off removing space after closing brace - `url() no-repeat` into `url()no-repeat` -* `'[+-]properties.urlQuotes'` - turn on / off `url()` quoting -* `'[+-]properties.zeroUnits'` - turn on / off units removal after a `0` value -* `'[+-]selectors.adjacentSpace'` - turn on / off extra space before `nav` element -* `'[+-]selectors.ie7Hack'` - turn on / off IE7 selector hack removal (`*+html...`) -* `'[+-]selectors.special'` - a regular expression with all special, unmergeable selectors (leave it empty unless you know what you are doing) -* `'[+-]units.ch'` - turn on / off treating `ch` as a proper unit -* `'[+-]units.in'` - turn on / off treating `in` as a proper unit -* `'[+-]units.pc'` - turn on / off treating `pc` as a proper unit -* `'[+-]units.pt'` - turn on / off treating `pt` as a proper unit -* `'[+-]units.rem'` - turn on / off treating `rem` as a proper unit -* `'[+-]units.vh'` - turn on / off treating `vh` as a proper unit -* `'[+-]units.vm'` - turn on / off treating `vm` as a proper unit -* `'[+-]units.vmax'` - turn on / off treating `vmax` as a proper unit -* `'[+-]units.vmin'` - turn on / off treating `vmin` as a proper unit -* `'[+-]units.vm'` - turn on / off treating `vm` as a proper unit - -For example, using `--compatibility 'ie8,+units.rem'` will ensure IE8 compatibility while enabling `rem` units so the following style `margin:0px 0rem` can be shortened to `margin:0`, while in pure IE8 mode it can't be. - -To pass a single off (-) switch in CLI please use the following syntax `--compatibility *,-units.rem`. - -In library mode you can also pass `compatibility` as a hash of options. - -### What advanced optimizations are applied? - -All advanced optimizations are dispatched [here](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/selectors/advanced.js#L59), and this is what they do: - -* `recursivelyOptimizeBlocks` - does all the following operations on a block (think `@media` or `@keyframe` at-rules); -* `recursivelyOptimizeProperties` - optimizes properties in rulesets and "flat at-rules" (like @font-face) by splitting them into components (e.g. `margin` into `margin-(*)`), optimizing, and rebuilding them back. You may want to use `shorthandCompacting` option to control whether you want to turn multiple (long-hand) properties into a shorthand ones; -* `removeDuplicates` - gets rid of duplicate rulesets with exactly the same set of properties (think of including the same Sass / Less partial twice for no good reason); -* `mergeAdjacent` - merges adjacent rulesets with the same selector or rules; -* `reduceNonAdjacent` - identifies which properties are overridden in same-selector non-adjacent rulesets, and removes them; -* `mergeNonAdjacentBySelector` - identifies same-selector non-adjacent rulesets which can be moved (!) to be merged, requires all intermediate rulesets to not redefine the moved properties, or if redefined to be either more coarse grained (e.g. `margin` vs `margin-top`) or have the same value; -* `mergeNonAdjacentByBody` - same as the one above but for same-rules non-adjacent rulesets; -* `restructure` - tries to reorganize different-selector different-rules rulesets so they take less space, e.g. `.one{padding:0}.two{margin:0}.one{margin-bottom:3px}` into `.two{margin:0}.one{padding:0;margin-bottom:3px}`; -* `removeDuplicateMediaQueries` - removes duplicated `@media` at-rules; -* `mergeMediaQueries` - merges non-adjacent `@media` at-rules by same rules as `mergeNonAdjacentBy*` above; - -## Acknowledgments (sorted alphabetically) - -* Anthony Barre ([@abarre](https://github.com/abarre)) for improvements to - `@import` processing, namely introducing the `--skip-import` / - `processImport` options. -* Simon Altschuler ([@altschuler](https://github.com/altschuler)) for fixing - `@import` processing inside comments. -* Isaac ([@facelessuser](https://github.com/facelessuser)) for pointing out - a flaw in clean-css' stateless mode. -* Jan Michael Alonzo ([@jmalonzo](https://github.com/jmalonzo)) for a patch - removing node.js' old `sys` package. -* Luke Page ([@lukeapage](https://github.com/lukeapage)) for suggestions and testing the source maps feature. - Plus everyone else involved in [#125](https://github.com/jakubpawlowicz/clean-css/issues/125) for pushing it forward. -* Timur Kristóf ([@Venemo](https://github.com/Venemo)) for an outstanding - contribution of advanced property optimizer for 2.2 release. -* Vincent Voyer ([@vvo](https://github.com/vvo)) for a patch with better - empty element regex and for inspiring us to do many performance improvements - in 0.4 release. -* [@XhmikosR](https://github.com/XhmikosR) for suggesting new features - (option to remove special comments and strip out URLs quotation) and - pointing out numerous improvements (JSHint, media queries). - -## License - -Clean-css is released under the [MIT License](https://github.com/jakubpawlowicz/clean-css/blob/master/LICENSE). diff --git a/node_modules/clean-css/bin/cleancss b/node_modules/clean-css/bin/cleancss deleted file mode 100755 index 72148cf..0000000 --- a/node_modules/clean-css/bin/cleancss +++ /dev/null @@ -1,184 +0,0 @@ -#!/usr/bin/env node - -var fs = require('fs'); -var path = require('path'); -var CleanCSS = require('../index'); - -var commands = require('commander'); - -var packageConfig = fs.readFileSync(path.join(path.dirname(fs.realpathSync(process.argv[1])), '../package.json')); -var buildVersion = JSON.parse(packageConfig).version; - -var isWindows = process.platform == 'win32'; -var lineBreak = require('os').EOL; - -// Specify commander options to parse command line params correctly -commands - .version(buildVersion, '-v, --version') - .usage('[options] source-file, [source-file, ...]') - .option('-b, --keep-line-breaks', 'Keep line breaks') - .option('-c, --compatibility [ie7|ie8]', 'Force compatibility mode (see Readme for advanced examples)') - .option('-d, --debug', 'Shows debug information (minification time & compression efficiency)') - .option('-o, --output [output-file]', 'Use [output-file] as output instead of STDOUT') - .option('-r, --root [root-path]', 'Set a root path to which resolve absolute @import rules') - .option('-s, --skip-import', 'Disable @import processing') - .option('-t, --timeout [seconds]', 'Per connection timeout when fetching remote @imports (defaults to 5 seconds)') - .option('--rounding-precision [n]', 'Rounds to `N` decimal places.
