For questions -and discussion, please use the -[Tern discussion forum](https://discuss.ternjs.net). - -## Installation - -The easiest way to install acorn is with [`npm`][npm]. - -[npm]: https://www.npmjs.com/ - -```sh -npm install acorn -``` - -Alternately, download the source. - -```sh -git clone https://github.com/ternjs/acorn.git -``` - -## Components - -When run in a CommonJS (node.js) or AMD environment, exported values -appear in the interfaces exposed by the individual files, as usual. -When loaded in the browser (Acorn works in any JS-enabled browser more -recent than IE5) without any kind of module management, a single -global object `acorn` will be defined, and all the exported properties -will be added to that. - -### Main parser - -This is implemented in `dist/acorn.js`, and is what you get when you -`require("acorn")` in node.js. - -**parse**`(input, options)` is used to parse a JavaScript program. -The `input` parameter is a string, `options` can be undefined or an -object setting some of the options listed below. 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, 6, or 7. This influences support for strict mode, the set - of reserved words, and support for new syntax features. Default is 6. - - **NOTE**: Only 'stage 4' (finalized) ECMAScript 7 features are being - implemented by Acorn. That means that most of the draft standard is - not yet being parsed. - -- **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 (regardless of the `location` option) 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 the callbacks as a third 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|--ecma7`: 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) - } -}) -``` - -### Existing plugins - - - [`acorn-jsx`](https://github.com/RReverser/acorn-jsx): Parse [Facebook JSX syntax extensions](https://github.com/facebook/jsx) - - [`acorn-es7-plugin`](https://github.com/MatAtBread/acorn-es7-plugin/): Parse [async/await syntax proposal](https://github.com/tc39/ecmascript-asyncawait) - - [`acorn-object-spread`](https://github.com/UXtemple/acorn-object-spread): Parse [object spread syntax proposal](https://github.com/sebmarkbage/ecmascript-rest-spread) - - [`acorn-es7`](https://www.npmjs.com/package/acorn-es7): Parse [decorator syntax proposal](https://github.com/wycats/javascript-decorators) - - [`acorn-objj`](https://www.npmjs.com/package/acorn-objj): [Objective-J](http://www.cappuccino-project.org/learn/objective-j.html) language parser built as Acorn plugin diff --git a/node_modules/acorn-jsx/node_modules/acorn/bin/acorn b/node_modules/acorn-jsx/node_modules/acorn/bin/acorn deleted file mode 100755 index cf4acd5..0000000 --- a/node_modules/acorn-jsx/node_modules/acorn/bin/acorn +++ /dev/null @@ -1,65 +0,0 @@ -#!/usr/bin/env node -'use strict'; - -var path = require('path'); -var fs = require('fs'); -var acorn = require('../dist/acorn.js'); - -var infile; -var forceFile; -var silent = false; -var compact = false; -var tokenize = false; -var options = {} - -function help(status) { - var print = (status == 0) ?

Espree is now built on top of [Acorn](https://github.com/ternjs/acorn), which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima. - -## Usage - -Install: - -``` -npm i espree --save -``` - -And in your Node.js code: - -```javascript -var espree = require("espree"); - -var ast = espree.parse(code); -``` - -There is a second argument to `parse()` that allows you to specify various options: - -```javascript -var espree = require("espree"); - -// Optional second options argument with the following default settings -var ast = espree.parse(code, { - - // attach range information to each node - range: false, - - // attach line/column location information to each node - loc: false, - - // create a top-level comments array containing all comments - comment: false, - - // attach comments to the closest relevant node as leadingComments and trailingComments - attachComment: false, - - // create a top-level tokens array containing all tokens - tokens: false, - - // Set to 3, 5 (default), 6, 7, 8, or 9 to specify the version of ECMAScript syntax you want to use. - // You can also set to 2015 (same as 6), 2016 (same as 7), 2017 (same as 8), or 2018 (same as 9) to use the year-based naming. - ecmaVersion: 5, - - // specify which type of script you're parsing ("script" or "module") - sourceType: "script", - - // specify additional language features - ecmaFeatures: { - - // enable JSX parsing - jsx: false, - - // enable return in global scope - globalReturn: false, - - // enable implied strict mode (if ecmaVersion >= 5) - impliedStrict: false, - - // allow experimental object rest/spread - experimentalObjectRestSpread: false - } -}); -``` - -## Esprima Compatibility Going Forward - -The primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the [ESTree](https://github.com/estree/estree) API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same. - -Espree may also deviate from Esprima in the interface it exposes. - -## Contributing - -Issues and pull requests will be triaged and responded to as quickly as possible. We operate under the [ESLint Contributor Guidelines](http://eslint.org/docs/developer-guide/contributing), so please be sure to read them before contributing. If you're not sure where to dig in, check out the [issues](https://github.com/eslint/espree/issues). - -Espree is licensed under a permissive BSD 2-clause license. - -## Build Commands - -* `npm test` - run all linting and tests -* `npm run lint` - run all linting -* `npm run browserify` - creates a version of Espree that is usable in a browser - -## Differences from Espree 2.x - -* The `tokenize()` method does not use `ecmaFeatures`. Any string will be tokenized completely based on ECMAScript 6 semantics. -* Trailing whitespace no longer is counted as part of a node. -* `let` and `const` declarations are no longer parsed by default. You must opt-in by using an `ecmaVersion` newer than `5` or setting `sourceType` to `module`. -* The `esparse` and `esvalidate` binary scripts have been removed. -* There is no `tolerant` option. We will investigate adding this back in the future. - -## Known Incompatibilities - -In an effort to help those wanting to transition from other parsers to Espree, the following is a list of noteworthy incompatibilities with other parsers. These are known differences that we do not intend to change. - -### Esprima 1.2.2 - -* Esprima counts trailing whitespace as part of each AST node while Espree does not. In Espree, the end of a node is where the last token occurs. -* Espree does not parse `let` and `const` declarations by default. -* Error messages returned for parsing errors are different. -* There are two addition properties on every node and token: `start` and `end`. These represent the same data as `range` and are used internally by Acorn. - -### Esprima 2.x - -* Esprima 2.x uses a different comment attachment algorithm that results in some comments being added in different places than Espree. The algorithm Espree uses is the same one used in Esprima 1.2.2. - -## Frequently Asked Questions - -### Why another parser - -[ESLint](http://eslint.org) had been relying on Esprima as its parser from the beginning. While that was fine when the JavaScript language was evolving slowly, the pace of development increased dramatically and Esprima had fallen behind. ESLint, like many other tools reliant on Esprima, has been stuck in using new JavaScript language features until Esprima updates, and that caused our users frustration. - -We decided the only way for us to move forward was to create our own parser, bringing us inline with JSHint and JSLint, and allowing us to keep implementing new features as we need them. We chose to fork Esprima instead of starting from scratch in order to move as quickly as possible with a compatible API. - -With Espree 2.0.0, we are no longer a fork of Esprima but rather a translation layer between Acorn and Esprima syntax. This allows us to put work back into a community-supported parser (Acorn) that is continuing to grow and evolve while maintaining an Esprima-compatible parser for those utilities still built on Esprima. - -### Have you tried working with Esprima? - -Yes. Since the start of ESLint, we've regularly filed bugs and feature requests with Esprima and will continue to do so. However, there are some different philosophies around how the projects work that need to be worked through. The initial goal was to have Espree track Esprima and eventually merge the two back together, but we ultimately decided that building on top of Acorn was a better choice due to Acorn's plugin support. - -### Why don't you just use Acorn? - -Acorn is a great JavaScript parser that produces an AST that is compatible with Esprima. Unfortunately, ESLint relies on more than just the AST to do its job. It relies on Esprima's tokens and comment attachment features to get a complete picture of the source code. We investigated switching to Acorn, but the inconsistencies between Esprima and Acorn created too much work for a project like ESLint. - -We are building on top of Acorn, however, so that we can contribute back and help make Acorn even better. - -### What ECMAScript 6 features do you support? - -All of them. - -### What ECMAScript 7/2016 features do you support? - -There is only one ECMAScript 2016 syntax change: the exponentiation operator. Espree supports this. - -### What ECMAScript 2017 features do you support? - -There are two ECMAScript 2017 syntax changes: `async` functions, and trailing commas in function declarations and calls. Espree supports both of them. - -### What ECMAScript 2018 features do you support? - -Because ECMAScript 2018 is still under development, we are implementing features as they are finalized. Currently, Espree supports: - -* Invalid escape sequences in tagged template literals - -### How do you determine which experimental features to support? - -In general, we do not support experimental JavaScript features. We may make exceptions from time to time depending on the maturity of the features. diff --git a/node_modules/espree/espree.js b/node_modules/espree/espree.js deleted file mode 100644 index b2f0a18..0000000 --- a/node_modules/espree/espree.js +++ /dev/null @@ -1,799 +0,0 @@ -/** - * @fileoverview Main Espree file that converts Acorn into Esprima output. - * - * This file contains code from the following MIT-licensed projects: - * 1.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - -'use strict'; - -module.exports = Transform; - -var Duplex = require('./_stream_duplex'); - -/**/ -var util = require('core-util-is'); -util.inherits = require('inherits'); -/**/ - -util.inherits(Transform, Duplex); - -function TransformState(stream) { - this.afterTransform = function (er, data) { - return afterTransform(stream, er, data); - }; - - this.needTransform = false; - this.transforming = false; - this.writecb = null; - this.writechunk = null; - this.writeencoding = null; -} - -function afterTransform(stream, er, data) { - var ts = stream._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return stream.emit('error', new Error('write callback called multiple times')); - } - - ts.writechunk = null; - ts.writecb = null; - - if (data !== null && data !== undefined) stream.push(data); - - cb(er); - - var rs = stream._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - stream._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - - Duplex.call(this, options); - - this._transformState = new TransformState(this); - - var stream = this; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - - if (typeof options.flush === 'function') this._flush = options.flush; - } - - // When the writable side finishes, then flush out anything remaining. - this.once('prefinish', function () { - if (typeof this._flush === 'function') this._flush(function (er, data) { - done(stream, er, data); - });else done(stream); - }); -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

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. - -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. - - -## Maintainers - -- [Sindre Sorhus](https://github.com/sindresorhus) -- [Josh Junon](https://github.com/qix-) - - -## License - -MIT diff --git a/node_modules/strip-ansi/package.json b/node_modules/strip-ansi/package.json index 7d40118..1b1f84b 100644 --- a/node_modules/strip-ansi/package.json +++ b/node_modules/strip-ansi/package.json @@ -1,29 +1,31 @@ { - "_from": "strip-ansi@^4.0.0", - "_id": "strip-ansi@4.0.0", + "_from": "strip-ansi@^6.0.0", + "_id": "strip-ansi@6.0.0", "_inBundle": false, - "_integrity": "sha1-qEeQIusaw2iocTibY1JixQXuNo8=", + "_integrity": "sha512-AuvKTrTfQNYNIctbR1K/YGTR1756GycPsg7b9bdV9Duqur4gv6aKqHXah67Z8ImS7WEz5QVcOtlfW2rZEugt6w==", "_location": "/strip-ansi", "_phantomChildren": {}, "_requested": { "type": "range", "registry": true, - "raw": "strip-ansi@^4.0.0", + "raw": "strip-ansi@^6.0.0", "name": "strip-ansi", "escapedName": "strip-ansi", - "rawSpec": "^4.0.0", + "rawSpec": "^6.0.0", "saveSpec": null, - "fetchSpec": "^4.0.0" + "fetchSpec": "^6.0.0" }, "_requiredBy": [ - "/eslint", - "/inquirer", - "/string-width" + "/@jest/core", + "/cliui", + "/string-length", + "/string-width", + "/wrap-ansi" ], - "_resolved": "https://registry.npmjs.org/strip-ansi/-/strip-ansi-4.0.0.tgz", - "_shasum": "a8479022eb1ac368a871389b635262c505ee368f", - "_spec": "strip-ansi@^4.0.0", - "_where": "/Users/cloyd/coderrr/odin/javascript-exercises/node_modules/eslint", + "_resolved": "https://registry.npmjs.org/strip-ansi/-/strip-ansi-6.0.0.tgz", + "_shasum": "0b1571dd7669ccd4f3e06e14ef1eed26225ae532", + "_spec": "strip-ansi@^6.0.0", + "_where": "/home/michael/projects/javascript-exercises/node_modules/@jest/core", "author": { "name": "Sindre Sorhus", "email": "sindresorhus@gmail.com", @@ -34,19 +36,21 @@ }, "bundleDependencies": false, "dependencies": { - "ansi-regex": "^3.0.0" + "ansi-regex": "^5.0.0" }, "deprecated": false, - "description": "Strip ANSI escape codes", + "description": "Strip ANSI escape codes from a string", "devDependencies": { - "ava": "*", - "xo": "*" + "ava": "^2.4.0", + "tsd": "^0.10.0", + "xo": "^0.25.3" }, "engines": { - "node": ">=4" + "node": ">=8" }, "files": [ - "index.js" + "index.js", + "index.d.ts" ], "homepage": "https://github.com/chalk/strip-ansi#readme", "keywords": [ @@ -80,7 +84,7 @@ "url": "git+https://github.com/chalk/strip-ansi.git" }, "scripts": { - "test": "xo && ava" + "test": "xo && ava && tsd" }, - "version": "4.0.0" + "version": "6.0.0" } diff --git a/node_modules/strip-ansi/readme.md b/node_modules/strip-ansi/readme.md index dc76f0c..7c4b56d 100644 --- a/node_modules/strip-ansi/readme.md +++ b/node_modules/strip-ansi/readme.md @@ -1,6 +1,6 @@ # strip-ansi [![Build Status](https://travis-ci.org/chalk/strip-ansi.svg?branch=master)](https://travis-ci.org/chalk/strip-ansi) -> Strip [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) +> Strip [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) from a string ## Install @@ -17,12 +17,23 @@ const stripAnsi = require('strip-ansi'); stripAnsi('\u001B[4mUnicorn\u001B[0m'); //=> 'Unicorn' + +stripAnsi('\u001B]8;;https://github.com\u0007Click\u001B]8;;\u0007'); +//=> 'Click' ``` +## strip-ansi for enterprise + +Available as part of the Tidelift Subscription. + +The maintainers of strip-ansi and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications.

Being a highly virtuous child, I believed all that I was told, and acquired a conscience which has kept me working hard down to the present moment. But although my conscience has controlled my actions, my opinions have undergone a revolution. I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached. Everyone knows the story of the traveler in Naples who saw twelve beggars lying in the sun (it was before the days of Mussolini), and offered a lira to the laziest of them. Eleven of them jumped up to claim it, so he gave it to the twelfth. this traveler was on the right lines. But in countries which do not enjoy Mediterranean sunshine idleness is more difficult, and a great public propaganda will be required to inaugurate it. I hope that, after reading the following pages, the leaders of the YMCA will start a campaign to induce good young men to do nothing. If so, I shall not have lived in vain. - -Before advancing my own arguments for laziness, I must dispose of one which I cannot accept. Whenever a person who already has enough to live on proposes to engage in some everyday kind of job, such as school-teaching or typing, he or she is told that such conduct takes the bread out of other people's mouths, and is therefore wicked. If this argument were valid, it would only be necessary for us all to be idle in order that we should all have our mouths full of bread. What people who say such things forget is that what a man earns he usually spends, and in spending he gives employment. As long as a man spends his income, he puts just as much bread into people's mouths in spending as he takes out of other people's mouths in earning. The real villain, from this point of view, is the man who saves. If he merely puts his savings in a stocking, like the proverbial French peasant, it is obvious that they do not give employment. If he invests his savings, the matter is less obvious, and different cases arise. - -One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling. - -But, I shall be told, the case is quite different when savings are invested in industrial enterprises. When such enterprises succeed, and produce something useful, this may be conceded. In these days, however, no one will deny that most enterprises fail. That means that a large amount of human labor, which might have been devoted to producing something that could be enjoyed, was expended on producing machines which, when produced, lay idle and did no good to anyone. The man who invests his savings in a concern that goes bankrupt is therefore injuring others as well as himself. If he spent his money, say, in giving parties for his friends, they (we may hope) would get pleasure, and so would all those upon whom he spent money, such as the butcher, the baker, and the bootlegger. But if he spends it (let us say) upon laying down rails for surface card in some place where surface cars turn out not to be wanted, he has diverted a mass of labor into channels where it gives pleasure to no one. Nevertheless, when he becomes poor through failure of his investment he will be regarded as a victim of undeserved misfortune, whereas the gay spendthrift, who has spent his money philanthropically, will be despised as a fool and a frivolous person. - -All this is only preliminary. I want to say, in all seriousness, that a great deal of harm is being done in the modern world by belief in the virtuousness of work, and that the road to happiness and prosperity lies in an organized diminution of work. - -First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid. The second kind is capable of indefinite extension: there are not only those who give orders, but those who give advice as to what orders should be given. Usually two opposite kinds of advice are given simultaneously by two organized bodies of men; this is called politics. The skill required for this kind of work is not knowledge of the subjects as to which advice is given, but knowledge of the art of persuasive speaking and writing, i.e. of advertising. - -Throughout Europe, though not in America, there is a third class of men, more respected than either of the classes of workers. There are men who, through ownership of land, are able to make others pay for the privilege of being allowed to exist and to work. These landowners are idle, and I might therefore be expected to praise them. Unfortunately, their idleness is only rendered possible by the industry of others; indeed their desire for comfortable idleness is historically the source of the whole gospel of work. The last thing they have ever wished is that others should follow their example. - -From the beginning of civilization until the Industrial Revolution, a man could, as a rule, produce by hard work little more than was required for the subsistence of himself and his family, although his wife worked at least as hard as he did, and his children added their labor as soon as they were old enough to do so. The small surplus above bare necessaries was not left to those who produced it, but was appropriated by warriors and priests. In times of famine there was no surplus; the warriors and priests, however, still secured as much as at other times, with the result that many of the workers died of hunger. This system persisted in Russia until 1917 [1], and still persists in the East; in England, in spite of the Industrial Revolution, it remained in full force throughout the Napoleonic wars, and until a hundred years ago, when the new class of manufacturers acquired power. In America, the system came to an end with the Revolution, except in the South, where it persisted until the Civil War. A system which lasted so long and ended so recently has naturally left a profound impress upon men's thoughts and opinions. Much that we take for granted about the desirability of work is derived from this system, and, being pre-industrial, is not adapted to the modern world. Modern technique has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery. - -It is obvious that, in primitive communities, peasants, left to themselves, would not have parted with the slender surplus upon which the warriors and priests subsisted, but would have either produced less or consumed more. At first, sheer force compelled them to produce and part with the surplus. Gradually, however, it was found possible to induce many of them to accept an ethic according to which it was their duty to work hard, although part of their work went to support others in idleness. By this means the amount of compulsion required was lessened, and the expenses of government were diminished. To this day, 99 per cent of British wage-earners would be genuinely shocked if it were proposed that the King should not have a larger income than a working man. The conception of duty, speaking historically, has been a means used by the holders of power to induce others to live for the interests of their masters rather than for their own. Of course the holders of power conceal this fact from themselves by managing to believe that their interests are identical with the larger interests of humanity. Sometimes this is true; Athenian slave-owners, for instance, employed part of their leisure in making a permanent contribution to civilization which would have been impossible under a just economic system. Leisure is essential to civilization, and in former times leisure for the few was only rendered possible by the labors of the many. But their labors were valuable, not because work is good, but because leisure is good. And with modern technique it would be possible to distribute leisure justly without injury to civilization. - -Modern technique has made it possible to diminish enormously the amount of labor required to secure the necessaries of life for everyone. This was made obvious during the war. At that time all the men in the armed forces, and all the men and women engaged in the production of munitions, all the men and women engaged in spying, war propaganda, or Government offices connected with the war, were withdrawn from productive occupations. In spite of this, the general level of well-being among unskilled wage-earners on the side of the Allies was higher than before or since. The significance of this fact was concealed by finance: borrowing made it appear as if the future was nourishing the present. But that, of course, would have been impossible; a man cannot eat a loaf of bread that does not yet exist. The war showed conclusively that, by the scientific organization of production, it is possible to keep modern populations in fair comfort on a small part of the working capacity of the modern world. If, at the end of the war, the scientific organization, which had been created in order to liberate men for fighting and munition work, had been preserved, and the hours of the week had been cut down to four, all would have been well. Instead of that the old chaos was restored, those whose work was demanded were made to work long hours, and the rest were left to starve as unemployed. Why? Because work is a duty, and a man should not receive wages in proportion to what he has produced, but in proportion to his virtue as exemplified by his industry. - -This is the morality of the Slave State, applied in circumstances totally unlike those in which it arose. No wonder the result has been disastrous. Let us take an illustration. Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined? - -The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion. - -Let us, for a moment, consider the ethics of work frankly, without superstition. Every human being, of necessity, consumes, in the course of his life, a certain amount of the produce of human labor. Assuming, as we may, that labor is on the whole disagreeable, it is unjust that a man should consume more than he produces. Of course he may provide services rather than commodities, like a medical man, for example; but he should provide something in return for his board and lodging. to this extent, the duty of work must be admitted, but to this extent only. - -I shall not dwell upon the fact that, in all modern societies outside the USSR, many people escape even this minimum amount of work, namely all those who inherit money and all those who marry money. I do not think the fact that these people are allowed to be idle is nearly so harmful as the fact that wage-earners are expected to overwork or starve. - -If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons. Oddly enough, while they wish their sons to work so hard as to have no time to be civilized, they do not mind their wives and daughters having no work at all. the snobbish admiration of uselessness, which, in an aristocratic society, extends to both sexes, is, under a plutocracy, confined to women; this, however, does not make it any more in agreement with common sense. - -The wise use of leisure, it must be conceded, is a product of civilization and education. A man who has worked long hours all his life will become bored if he becomes suddenly idle. But without a considerable amount of leisure a man is cut off from many of the best things. There is no longer any reason why the bulk of the population should suffer this deprivation; only a foolish asceticism, usually vicarious, makes us continue to insist on work in excessive quantities now that the need no longer exists. - -In the new creed which controls the government of Russia, while there is much that is very different from the traditional teaching of the West, there are some things that are quite unchanged. The attitude of the governing classes, and especially of those who conduct educational propaganda, on the subject of the dignity of labor, is almost exactly that which the governing classes of the world have always preached to what were called the 'honest poor'. Industry, sobriety, willingness to work long hours for distant advantages, even submissiveness to authority, all these reappear; moreover authority still represents the will of the Ruler of the Universe, Who, however, is now called by a new name, Dialectical Materialism. - -The victory of the proletariat in Russia has some points in common with the victory of the feminists in some other countries. For ages, men had conceded the superior saintliness of women, and had consoled women for their inferiority by maintaining that saintliness is more desirable than power. At last the feminists decided that they would have both, since the pioneers among them believed all that the men had told them about the desirability of virtue, but not what they had told them about the worthlessness of political power. A similar thing has happened in Russia as regards manual work. For ages, the rich and their sycophants have written in praise of 'honest toil', have praised the simple life, have professed a religion which teaches that the poor are much more likely to go to heaven than the rich, and in general have tried to make manual workers believe that there is some special nobility about altering the position of matter in space, just as men tried to make women believe that they derived some special nobility from their sexual enslavement. In Russia, all this teaching about the excellence of manual work has been taken seriously, with the result that the manual worker is more honored than anyone else. What are, in essence, revivalist appeals are made, but not for the old purposes: they are made to secure shock workers for special tasks. Manual work is the ideal which is held before the young, and is the basis of all ethical teaching. - -For the present, possibly, this is all to the good. A large country, full of natural resources, awaits development, and has has to be developed with very little use of credit. In these circumstances, hard work is necessary, and is likely to bring a great reward. But what will happen when the point has been reached where everybody could be comfortable without working long hours? - -In the West, we have various ways of dealing with this problem. We have no attempt at economic justice, so that a large proportion of the total produce goes to a small minority of the population, many of whom do no work at all. Owing to the absence of any central control over production, we produce hosts of things that are not wanted. We keep a large percentage of the working population idle, because we can dispense with their labor by making the others overwork. When all these methods prove inadequate, we have a war: we cause a number of people to manufacture high explosives, and a number of others to explode them, as if we were children who had just discovered fireworks. By a combination of all these devices we manage, though with difficulty, to keep alive the notion that a great deal of severe manual work must be the lot of the average man. - -In Russia, owing to more economic justice and central control over production, the problem will have to be differently solved. the rational solution would be, as soon as the necessaries and elementary comforts can be provided for all, to reduce the hours of labor gradually, allowing a popular vote to decide, at each stage, whether more leisure or more goods were to be preferred. But, having taught the supreme virtue of hard work, it is difficult to see how the authorities can aim at a paradise in which there will be much leisure and little work. It seems more likely that they will find continually fresh schemes, by which present leisure is to be sacrificed to future productivity. I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea. An admirable project, but liable to postpone proletarian comfort for a generation, while the nobility of toil is being displayed amid the ice-fields and snowstorms of the Arctic Ocean. This sort of thing, if it happens, will be the result of regarding the virtue of hard work as an end in itself, rather than as a means to a state of affairs in which it is no longer needed. - -The fact is that moving matter about, while a certain amount of it is necessary to our existence, is emphatically not one of the ends of human life. If it were, we should have to consider every navvy superior to Shakespeare. We have been misled in this matter by two causes. One is the necessity of keeping the poor contented, which has led the rich, for thousands of years, to preach the dignity of labor, while taking care themselves to remain undignified in this respect. The other is the new pleasure in mechanism, which makes us delight in the astonishingly clever changes that we can produce on the earth's surface. Neither of these motives makes any great appeal to the actual worker. If you ask him what he thinks the best part of his life, he is not likely to say: 'I enjoy manual work because it makes me feel that I am fulfilling man's noblest task, and because I like to think how much man can transform his planet. It is true that my body demands periods of rest, which I have to fill in as best I may, but I am never so happy as when the morning comes and I can return to the toil from which my contentment springs.' I have never heard working men say this sort of thing. They consider work, as it should be considered, a necessary means to a livelihood, and it is from their leisure that they derive whatever happiness they may enjoy. - -It will be said that, while a little leisure is pleasant, men would not know how to fill their days if they had only four hours of work out of the twenty-four. In so far as this is true in the modern world, it is a condemnation of our civilization; it would not have been true at any earlier period. There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake. Serious-minded persons, for example, are continually condemning the habit of going to the cinema, and telling us that it leads the young into crime. But all the work that goes to producing a cinema is respectable, because it is work, and because it brings a money profit. The notion that the desirable activities are those that bring a profit has made everything topsy-turvy. The butcher who provides you with meat and the baker who provides you with bread are praiseworthy, because they are making money; but when you enjoy the food they have provided, you are merely frivolous, unless you eat only to get strength for your work. Broadly speaking, it is held that getting money is good and spending money is bad. Seeing that they are two sides of one transaction, this is absurd; one might as well maintain that keys are good, but keyholes are bad. Whatever merit there may be in the production of goods must be entirely derivative from the advantage to be obtained by consuming them. The individual, in our society, works for profit; but the social purpose of his work lies in the consumption of what he produces. It is this divorce between the individual and the social purpose of production that makes it so difficult for men to think clearly in a world in which profit-making is the incentive to industry. We think too much of production, and too little of consumption. One result is that we attach too little importance to enjoyment and simple happiness, and that we do not judge production by the pleasure that it gives to the consumer. - -When I suggest that working hours should be reduced to four, I am not meaning to imply that all the remaining time should necessarily be spent in pure frivolity. I mean that four hours' work a day should entitle a man to the necessities and elementary comforts of life, and that the rest of his time should be his to use as he might see fit. It is an essential part of any such social system that education should be carried further than it usually is at present, and should aim, in part, at providing tastes which would enable a man to use leisure intelligently. I am not thinking mainly of the sort of things that would be considered 'highbrow'. Peasant dances have died out except in remote rural areas, but the impulses which caused them to be cultivated must still exist in human nature. The pleasures of urban populations have become mainly passive: seeing cinemas, watching football matches, listening to the radio, and so on. This results from the fact that their active energies are fully taken up with work; if they had more leisure, they would again enjoy pleasures in which they took an active part. - -In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges. These facts greatly diminished its excellence, but in spite of this drawback it contributed nearly the whole of what we call civilization. It cultivated the arts and discovered the sciences; it wrote the books, invented the philosophies, and refined social relations. Even the liberation of the oppressed has usually been inaugurated from above. Without the leisure class, mankind would never have emerged from barbarism. - -The method of a leisure class without duties was, however, extraordinarily wasteful. None of the members of the class had to be taught to be industrious, and the class as a whole was not exceptionally intelligent. The class might produce one Darwin, but against him had to be set tens of thousands of country gentlemen who never thought of anything more intelligent than fox-hunting and punishing poachers. At present, the universities are supposed to provide, in a more systematic way, what the leisure class provided accidentally and as a by-product. This is a great improvement, but it has certain drawbacks. University life is so different from life in the world at large that men who live in academic milieu tend to be unaware of the preoccupations and problems of ordinary men and women; moreover their ways of expressing themselves are usually such as to rob their opinions of the influence that they ought to have upon the general public. Another disadvantage is that in universities studies are organized, and the man who thinks of some original line of research is likely to be discouraged. Academic institutions, therefore, useful as they are, are not adequate guardians of the interests of civilization in a world where everyone outside their walls is too busy for unutilitarian pursuits. - -In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue. - -Above all, there will be happiness and joy of life, instead of frayed nerves, weariness, and dyspepsia. The work exacted will be enough to make leisure delightful, but not enough to produce exhaustion. Since men will not be tired in their spare time, they will not demand only such amusements as are passive and vapid. At least one per cent will probably devote the time not spent in professional work to pursuits of some public importance, and, since they will not depend upon these pursuits for their livelihood, their originality will be unhampered, and there will be no need to conform to the standards set by elderly pundits. But it is not only in these exceptional cases that the advantages of leisure will appear. Ordinary men and women, having the opportunity of a happy life, will become more kindly and less persecuting and less inclined to view others with suspicion. The taste for war will die out, partly for this reason, and partly because it will involve long and severe work for all. Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish forever. - -[1] Since then, members of the Communist Party have succeeded to this privilege of the warriors and priests. diff --git a/node_modules/wordwrap/test/wrap.js b/node_modules/wordwrap/test/wrap.js deleted file mode 100644 index 01ea471..0000000 --- a/node_modules/wordwrap/test/wrap.js +++ /dev/null @@ -1,33 +0,0 @@ -var test = require('tape'); -var wordwrap = require('../'); - -var fs = require('fs'); -var idleness = fs.readFileSync(__dirname + '/idleness.txt', 'utf8'); - -test('stop80', function (t) { - var lines = wordwrap(80)(idleness).split(/\n/); - var words = idleness.split(/\s+/); - - lines.forEach(function (line) { - t.ok(line.length <= 80, 'line > 80 columns'); - var chunks = line.match(/\S/) ? line.split(/\s+/) : []; - t.deepEqual(chunks, words.splice(0, chunks.length)); - }); - t.end(); -}); - -test('start20stop60', function (t) { - var lines = wordwrap(20, 100)(idleness).split(/\n/); - var words = idleness.split(/\s+/); - - lines.forEach(function (line) { - t.ok(line.length <= 100, 'line > 100 columns'); - var chunks = line - .split(/\s+/) - .filter(function (x) { return x.match(/\S/) }) - ; - t.deepEqual(chunks, words.splice(0, chunks.length)); - t.deepEqual(line.slice(0, 20), new Array(20 + 1).join(' ')); - }); - t.end(); -}); diff --git a/node_modules/wrappy/package.json b/node_modules/wrappy/package.json index 868205c..47cdeb6 100644 --- a/node_modules/wrappy/package.json +++ b/node_modules/wrappy/package.json @@ -22,7 +22,7 @@ "_resolved": "https://registry.npmjs.org/wrappy/-/wrappy-1.0.2.tgz", "_shasum": "b5243d8f3ec1aa35f1364605bc0d1036e30ab69f", "_spec": "wrappy@1", - "_where": "/Users/cloyd/coderrr/odin/javascript-exercises/node_modules/inflight", + "_where": "/home/michael/projects/javascript-exercises/node_modules/inflight", "author": { "name": "Isaac Z.
