Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. - -Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .option('--no-sauce', 'Remove sauce') - .parse(process.argv); - -console.log('you ordered a pizza'); -if (program.sauce) console.log(' with sauce'); -else console.log(' without sauce'); -``` - -To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs. - -e.g. ```.option('-m --myarg [myVar]', 'my super cool description')``` - -Then to access the input if it was passed in. - -e.g. ```var myInput = program.myarg``` - -**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in. - - -## Version option - -Calling the `version` implicitly adds the `-V` and `--version` options to the command. -When either of these options is present, the command prints the version number and exits. - - $ ./examples/pizza -V - 0.0.1 - -If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method. - -```js -program - .version('0.0.1', '-v, --version') -``` - -The version flags can be named anything, but the long option is required. - -## Command-specific options - -You can attach options to a command. - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .command('rm ') - .option('-r, --recursive', 'Remove recursively') - .action(function (dir, cmd) { - console.log('remove ' + dir + (cmd.recursive ?

This applies to `program.args` as well as the argument passed - to your action as demonstrated above. - -## Specify the argument syntax - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .version('0.1.0') - .arguments(' [env]') - .action(function (cmd, env) { - cmdValue = cmd; - envValue = env; - }); - -program.parse(process.argv); - -if (typeof cmdValue === 'undefined') { - console.error('no command given!'); - process.exit(1); -} -console.log('command:', cmdValue); -console.log('environment:', envValue || "no environment given"); -``` -Angled brackets (e.g. ``) indicate required input.

This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools. -The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`. - -Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified. - -If the program is designed to be installed globally, make sure the executables have proper modes, like `755`. - -### `--harmony` - -You can enable `--harmony` option in two ways: -* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern. -* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process. - -## Automated --help - - The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free: - -``` -$ ./examples/pizza --help -Usage: pizza [options] - -An application for pizzas ordering - -Options: - -h, --help output usage information - -V, --version output the version number - -p, --peppers Add peppers - -P, --pineapple Add pineapple - -b, --bbq Add bbq sauce - -c, --cheese Add the specified type of cheese [marble] - -C, --no-cheese You do not want any cheese -``` - -## Custom help - - You can display arbitrary `-h, --help` information - by listening for "--help". Commander will automatically - exit once you are done so that the remainder of your program - does not execute causing undesired behaviors, for example - in the following executable "stuff" will not output when - `--help` is used. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander');

- console.log(' $ custom-help --help'); - console.log(' $ custom-help -h'); -}); - -program.parse(process.argv); - -console.log('stuff'); -``` - -Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run: - -``` -Usage: custom-help [options] - -Options: - -h, --help output usage information - -V, --version output the version number - -f, --foo enable some foo - -b, --bar enable some bar - -B, --baz enable some baz - -Examples: - $ custom-help --help - $ custom-help -h -``` - -## .outputHelp(cb) - -Output help information without exiting. -Optional callback cb allows post-processing of help text before it is displayed. - -If you want to display help by default (e.g. if no command was provided), you can use something like: - -```js -var program = require('commander'); -var colors = require('colors'); - -program - .version('0.1.0') - .command('getstream [url]', 'get stream URL') - .parse(process.argv); - -if (!process.argv.slice(2).length) { - program.outputHelp(make_red); -} - -function make_red(txt) { - return colors.red(txt); //display the help text in red on the console -} -``` - -## .help(cb) - - Output help information and exit immediately. - Optional callback cb allows post-processing of help text before it is displayed. - - -## Custom event listeners - You can execute custom actions by listening to command and option events. - -```js -program.on('option:verbose', function () { - process.env.VERBOSE = this.verbose; -}); - -// error on unknown commands -program.on('command:*', function () { - console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' ')); - process.exit(1);

// 自定义规则 -html = xss('', options); -``` - -如果不想每次都传入一个 `options` 参数，可以创建一个 `FilterXSS` 实例（使用这种方法速度更快）： - -``` -options = {}; // 自定义规则 -myxss = new xss.FilterXSS(options); -// 以后直接调用 myxss.process() 来处理即可 -html = myxss.process(''); -``` - -`options` 参数的详细说明见下文。 - -### 白名单 - -通过 `whiteList` 来指定，格式为：`{'标签名': ['属性1', '属性2']}`。不在白名单上的标签将被过滤，不在白名单上的属性也会被过滤。以下是示例： - -```javascript -// 只允许a标签，该标签只允许href, title, target这三个属性 -var options = { - whiteList: { - a: ["href", "title", "target"] - } -}; -// 使用以上配置后，下面的HTML -// 大家好 -// 将被过滤为 -// 大家好 -``` - -默认白名单参考 `xss.whiteList`。 - -### 自定义匹配到标签时的处理方法 - -通过 `onTag` 来指定相应的处理函数。以下是详细说明： - -```javascript -function onTag(tag, html, options) { - // tag是当前的标签名称，比如标签，则tag的值是'a' - // html是该标签的HTML，比如标签，则html的值是'' - // options是一些附加的信息，具体如下： - // isWhite boolean类型，表示该标签是否在白名单上 - // isClosing boolean类型，表示该标签是否为闭合标签，比如时为true - // position integer类型，表示当前标签在输出的结果中的起始位置 - // sourcePosition integer类型，表示当前标签在原HTML中的起始位置 - // 如果返回一个字符串，则当前标签将被替换为该字符串 - // 如果不返回任何值，则使用默认的处理方法： - // 在白名单上： 通过onTagAttr来过滤属性，详见下文 - // 不在白名单上：通过onIgnoreTag指定，详见下文 -} -``` - -### 自定义匹配到标签的属性时的处理方法 - -通过 `onTagAttr` 来指定相应的处理函数。以下是详细说明： - -```javascript -function onTagAttr(tag, name, value, isWhiteAttr) { - // tag是当前的标签名称，比如标签，则tag的值是'a' - // name是当前属性的名称，比如href="#"，则name的值是'href' - // value是当前属性的值，比如href="#"，则value的值是'#' - // isWhiteAttr是否为白名单上的属性 - // 如果返回一个字符串，则当前属性值将被替换为该字符串 - // 如果不返回任何值，则使用默认的处理方法 - // 在白名单上： 调用safeAttrValue来过滤属性值，并输出该属性，详见下文 - // 不在白名单上：通过onIgnoreTagAttr指定，详见下文 -} -``` - -### 自定义匹配到不在白名单上的标签时的处理方法 - -通过 `onIgnoreTag` 来指定相应的处理函数。以下是详细说明： - -```javascript -function onIgnoreTag(tag, html, options) { - // 参数说明与onTag相同 - // 如果返回一个字符串，则当前标签将被替换为该字符串 - // 如果不返回任何值，则使用默认的处理方法（通过escape指定，详见下文） -} -``` - -### 自定义匹配到不在白名单上的属性时的处理方法 - -通过 `onIgnoreTagAttr` 来指定相应的处理函数。以下是详细说明： - -```javascript -function onIgnoreTagAttr(tag, name, value, isWhiteAttr) { - // 参数说明与onTagAttr相同 - // 如果返回一个字符串，则当前属性值将被替换为该字符串 - // 如果不返回任何值，则使用默认的处理方法（删除该属） -} -``` - -### 自定义 HTML 转义函数 - -通过 `escapeHtml` 来指定相应的处理函数。以下是默认代码 **（不建议修改）** ： - -```javascript -function escapeHtml(html) { - return html.replace(//g, ">"); -} -``` - -### 自定义标签属性值的转义函数 - -通过 `safeAttrValue` 来指定相应的处理函数。以下是详细说明： - -```javascript -function safeAttrValue(tag, name, value) { - // 参数说明与onTagAttr相同（没有options参数） - // 返回一个字符串表示该属性值 -} -``` - -### 自定义 CSS 过滤器 - -如果配置中允许了标签的 `style` 属性，则它的值会通过[cssfilter](https://github.com/leizongmin/js-css-filter) 模块处理。 -`cssfilter` 模块包含了一个默认的 CSS 白名单，你可以通过以下的方式配置： - -```javascript -myxss = new xss.FilterXSS({ - css: { - whiteList: { - position: /^fixed|relative$/, - top: true, - left: true - } - } -}); -html = myxss.process(''); -``` - -如果不想使用 CSS 过滤器来处理 `style` 属性的内容，可指定 `css` 选项的值为 `false`： - -```javascript -myxss = new xss.FilterXSS({ - css: false -}); -``` - -要获取更多的帮助信息可看这里：https://github.com/leizongmin/js-css-filter - -### 快捷配置 - -#### 去掉不在白名单上的标签 - -通过 `stripIgnoreTag` 来设置： - -* `true`：去掉不在白名单上的标签 -* `false`：（默认），使用配置的`escape`函数对该标签进行转义 - -示例： - -当设置 `stripIgnoreTag = true`时，以下代码 - -```html -code: -``` - -过滤后将输出 - -```html -code:alert(/xss/); -``` - -#### 去掉不在白名单上的标签及标签体 - -通过 `stripIgnoreTagBody` 来设置： - -* `false|null|undefined`：（默认），不特殊处理 -* `'*'|true`：去掉所有不在白名单上的标签 -* `['tag1', 'tag2']`：仅去掉指定的不在白名单上的标签 - -示例： - -当设置 `stripIgnoreTagBody = ['script']`时，以下代码 - -```html -code: -``` - -过滤后将输出 - -```html -code: -``` - -#### 去掉 HTML 备注 - -通过 `allowCommentTag` 来设置： - -* `true`：不处理 -* `false`：（默认），自动去掉 HTML 中的备注 - -示例： - -当设置 `allowCommentTag = false` 时，以下代码 - -```html -code: END -``` - -过滤后将输出 - -```html -code: END -``` - -## 应用实例 - -### 允许标签以 data-开头的属性 - -```javascript -var source = '
