[![Dependency Status](https://david-dm.org/mysticatea/vue-eslint-parser.svg)](https://david-dm.org/mysticatea/vue-eslint-parser)
The ESLint custom parser for `.vue` files.
## ⤴️ Motivation
This parser allows us to lint the `<template>` of `.vue` files. We can make mistakes easily on `<template>` if we use complex directives and expressions in the template. This parser and the rules of [eslint-plugin-vue](https://github.com/vuejs/eslint-plugin-vue) would catch some of the mistakes.
## 💿 Installation
```bash
$ npm install --save-dev eslint vue-eslint-parser
```
- Requires Node.js 6.5.0 or later.
- Requires ESLint 5.0.0 or later.
- Requires `babel-eslint` 8.1.1 or later if you want it. (optional)
- Requires `@typescript-eslint/parser` 1.0.0 or later if you want it. (optional)
## 📖 Usage
1. Write `parser` option into your `.eslintrc.*` file.
2. Use glob patterns or `--ext .vue` CLI option.
```json
{
"extends": "eslint:recommended",
"parser": "vue-eslint-parser"
}
```
```console
$ eslint "src/**/*.{js,vue}"
# or
$ eslint src --ext .vue
```
## 🔧 Options
`parserOptions` has the same properties as what [espree](https://github.com/eslint/espree#usage), the default parser of ESLint, is supporting.
For example:
```json
{
"parser": "vue-eslint-parser",
"parserOptions": {
"sourceType": "module",
"ecmaVersion": 2018,
"ecmaFeatures": {
"globalReturn": false,
"impliedStrict": false,
"jsx": false
}
}
}
```
### parserOptions.parser
You can use `parserOptions.parser` property to specify a custom parser to parse `<script>` tags.
Other properties than parser would be given to the specified parser.
For example:
```json
{
"parser": "vue-eslint-parser",
"parserOptions": {
"parser": "babel-eslint",
"sourceType": "module",
"allowImportExportEverywhere": false
}
}
```
```json
{
"parser": "vue-eslint-parser",
"parserOptions": {
"parser": "@typescript-eslint/parser"
}
}
```
If the `parserOptions.parser` is `false`, the `vue-eslint-parser` skips parsing `<script>` tags completely.
This is useful for people who use the language ESLint community doesn't provide custom parser implementation.
## 🎇 Usage for custom rules / plugins
- This parser provides `parserServices` to traverse `<template>`.
- `defineTemplateBodyVisitor(templateVisitor, scriptVisitor)` ... returns ESLint visitor to traverse `<template>`.
- `getTemplateBodyTokenStore()` ... returns ESLint `TokenStore` to get the tokens of `<template>`.
- `getDocumentFragment()` ... returns the root `VDocumentFragment`.
- [ast.md](./docs/ast.md) is `<template>` AST specification.
- [mustache-interpolation-spacing.js](https://github.com/vuejs/eslint-plugin-vue/blob/b434ff99d37f35570fa351681e43ba2cf5746db3/lib/rules/mustache-interpolation-spacing.js) is an example.
## ⚠️ Known Limitations
Some rules make warnings due to the outside of `<script>` tags.
Please disable those rules for `.vue` files as necessary.
- [eol-last](http://eslint.org/docs/rules/eol-last)
- [linebreak-style](http://eslint.org/docs/rules/linebreak-style)
- [max-len](http://eslint.org/docs/rules/max-len)
- [max-lines](http://eslint.org/docs/rules/max-lines)
- [no-trailing-spaces](http://eslint.org/docs/rules/no-trailing-spaces)
- [unicode-bom](http://eslint.org/docs/rules/unicode-bom)
- Other rules which are using the source code text instead of AST might be confused as well.
## 📰 Changelog
- [GitHub Releases](https://github.com/mysticatea/vue-eslint-parser/releases)
## 🍻 Contributing
Welcome contributing!
Please use GitHub's Issues/PRs.
If you want to write code, please execute `npm install && npm run setup` after you cloned this repository.
The `npm install` command installs dependencies.
The `npm run setup` command initializes ESLint as git submodules for tests.
### Development Tools
- `npm test` runs tests and measures coverage.
- `npm run build` compiles TypeScript source code to `index.js`, `index.js.map`, and `index.d.ts`.
- `npm run coverage` shows the coverage result of `npm test` command with the default browser.
- `npm run clean` removes the temporary files which are created by `npm test` and `npm run build`.
- `npm run lint` runs ESLint.
- `npm run setup` setups submodules to develop.
- `npm run update-fixtures` updates files in `test/fixtures/ast` directory based on `test/fixtures/ast/*/source.vue` files.
- `npm run watch` runs `build`, `update-fixtures`, and tests with `--watch` option.

# debug
[![Build Status](https://travis-ci.org/visionmedia/debug.svg?branch=master)](https://travis-ci.org/visionmedia/debug) [![Coverage Status](https://coveralls.io/repos/github/visionmedia/debug/badge.svg?branch=master)](https://coveralls.io/github/visionmedia/debug?branch=master) [![Slack](https://visionmedia-community-slackin.now.sh/badge.svg)](https://visionmedia-community-slackin.now.sh/) [![OpenCollective](https://opencollective.com/debug/backers/badge.svg)](#backers)

<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
A tiny JavaScript debugging utility modelled after Node.js core's debugging
technique. Works in Node.js and web browsers.
## Installation
```bash
$ npm install debug
```
## Usage
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. 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_](./examples/node/app.js):
```js
var debug = require('debug')('http')
, http = require('http')
, name = 'My App';
// fake app
debug('booting %o', 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_](./examples/node/worker.js):
```js
var a = require('debug')('worker:a')
, b = require('debug')('worker:b');
function work() {
a('doing lots of uninteresting work');
setTimeout(work, Math.random() * 1000);
}
work();
function workb() {
b('doing some work');
setTimeout(workb, Math.random() * 2000);
}
workb();
```
The `DEBUG` environment variable is then used to enable these based on space or
comma-delimited names.
Here are some examples:
<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
#### Windows command prompt notes
##### CMD
On Windows the environment variable is set using the `set` command.
```cmd
set DEBUG=*,-not_this
```
Example:
```cmd
set DEBUG=* & node app.js
```
##### PowerShell (VS Code default)
PowerShell uses different syntax to set environment variables.
```cmd
$env:DEBUG = "*,-not_this"
```
Example:
```cmd
$env:DEBUG='app';node app.js
```
Then, run the program to be debugged as usual.
npm script example:
```js
"windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
```
## Namespace Colors
Every debug instance has a color generated for it based on its namespace name.
This helps when visually parsing the debug output to identify which debug instance
a debug line belongs to.
#### Node.js
In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
otherwise debug will only use a small handful of basic colors.
<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
#### Web Browser
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
option. These are WebKit web inspectors, Firefox ([since version
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
and the Firebug plugin for Firefox (any version).
<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
## 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.
<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.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". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
## 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_HIDE_DATE` | Hide date from debug output (non-TTY). |
| `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);
```
## Output streams
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
Example [_stdout.js_](./examples/node/stdout.js):
```js
var debug = require('debug');
var error = debug('app:error');
// by default stderr is used
error('goes to stderr!');
var log = debug('app:log');
// set this namespace to log via console.log
log.log = console.log.bind(console); // don't forget to bind to console!
log('goes to stdout');
error('still goes to stderr!');
// set all output to go via console.info
// overrides all per-namespace log settings
debug.log = console.info.bind(console);
error('now goes to stdout via console.info');
log('still goes to stdout, but via console.info now');
```
## Extend
You can simply extend debugger
```js
const log = require('debug')('auth');
//creates new debug instance with extended namespace
const logSign = log.extend('sign');
const logLogin = log.extend('login');
log('hello'); // auth hello
logSign('hello'); //auth:sign hello
logLogin('hello'); //auth:login hello
```
## Set dynamically
You can also enable debug dynamically by calling the `enable()` method :
```js
let debug = require('debug');
console.log(1, debug.enabled('test'));
debug.enable('test');
console.log(2, debug.enabled('test'));
debug.disable();
console.log(3, debug.enabled('test'));
```
print :
```
1 false
2 true
3 false
```
Usage :
`enable(namespaces)`
`namespaces` can include modes separated by a colon and wildcards.
Note that calling `enable()` completely overrides previously set DEBUG variable :
```
$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
=> false
```
`disable()`
Will disable all namespaces. The functions returns the namespaces currently
enabled (and skipped). This can be useful if you want to disable debugging
temporarily without knowing what was enabled to begin with.
For example:
```js
let debug = require('debug');
debug.enable('foo:*,-foo:bar');
let namespaces = debug.disable();
debug.enable(namespaces);
```
Note: There is no guarantee that the string will be identical to the initial
enable string, but semantically they will be identical.
## Checking whether a debug target is enabled
After you've created a debug instance, you can determine whether or not it is
enabled by checking the `enabled` property:
```javascript
const debug = require('debug')('http');
if (debug.enabled) {
// do stuff...
}
```
You can also manually toggle this property to force the debug instance to be
enabled or disabled.

# ESLint Scope
ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
## Usage
Install:
```
npm i eslint-scope --save
```
Example:
```js
var eslintScope = require('eslint-scope');
var espree = require('espree');
var estraverse = require('estraverse');
var ast = espree.parse(code);
var scopeManager = eslintScope.analyze(ast);
var currentScope = scopeManager.acquire(ast); // global scope
estraverse.traverse(ast, {
enter: function(node, parent) {
// do stuff
if (/Function/.test(node.type)) {
currentScope = scopeManager.acquire(node); // get current function scope
}
},
leave: function(node, parent) {
if (/Function/.test(node.type)) {
currentScope = currentScope.upper; // set to parent scope
}
// do stuff
}
});
```

# ms
[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
[![Join the community on Spectrum](https://withspectrum.github.io/badge/badge.svg)](https://spectrum.chat/zeit)
Use this package to easily convert various time formats to milliseconds.
## Examples
```js
ms('2 days') // 172800000
ms('1d') // 86400000
ms('10h') // 36000000
ms('2.5 hrs') // 9000000
ms('2h') // 7200000
ms('1m') // 60000
ms('5s') // 5000
ms('1y') // 31557600000
ms('100') // 100
ms('-3 days') // -259200000
ms('-1h') // -3600000
ms('-200') // -200
```
### Convert from Milliseconds
```js
ms(60000) // "1m"
ms(2 * 60000) // "2m"
ms(-3 * 60000) // "-3m"
ms(ms('10 hours')) // "10h"
```
### Time Format Written-Out
```js
ms(60000, { long: true }) // "1 minute"
ms(2 * 60000, { long: true }) // "2 minutes"
ms(-3 * 60000, { long: true }) // "-3 minutes"
ms(ms('10 hours'), { long: true }) // "10 hours"
```
## Features
- Works both in [Node.js](https://nodejs.org) and in the browser
- If a number is supplied to `ms`, a string with a unit is returned
- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
## Related Packages
- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
## Caught a Bug?
1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
2. Link the package to the global module directory: `npm link`
3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
As always, you can run the tests using: `npm test`
