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 <dir>') - .option('-r, --recursive', 'Remove recursively') - .action(function (dir, cmd) { - console.log('remove ' + dir + (cmd.recursive ?

However, if an action-based command does not define an action, then the options are not validated. - -## Coercion - -```js -function range(val) { - return val.split('..').map(Number); -} - -function list(val) { - return val.split(','); -} - -function collect(val, memo) { - memo.push(val); - return memo; -} - -function increaseVerbosity(v, total) { - return total + 1; -} - -program - .version('0.1.0') - .usage('[options] <file ...>') - .option('-i, --integer <n>', 'An integer argument', parseInt) - .option('-f, --float <n>', 'A float argument', parseFloat) - .option('-r, --range <a>..<b>', 'A range', range) - .option('-l, --list <items>', 'A list', list) - .option('-o, --optional [value]', 'An optional value') - .option('-c, --collect [value]', 'A repeatable value', collect, []) - .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0) - .parse(process.argv); - -console.log(' int: %j', program.integer); -console.log(' float: %j', program.float); -console.log(' optional: %j', program.optional); -program.range = program.range || []; -console.log(' range: %j..%j', program.range[0], program.range[1]); -console.log(' list: %j', program.list); -console.log(' collect: %j', program.collect); -console.log(' verbosity: %j', program.verbose); -console.log(' args: %j', program.args); -``` - -## Regular Expression -```js -program - .version('0.1.0') - .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium') - .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i) - .parse(process.argv); - -console.log(' size: %j', program.size); -console.log(' drink: %j', program.drink); -``` - -## Variadic arguments - - The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to - append `...` to the argument name. Here is an example: - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .command('rmdir <dir> [otherDirs...]') - .action(function (dir, otherDirs) { - console.log('rmdir %s', dir); - if (otherDirs) { - otherDirs.forEach(function (oDir) { - console.log('rmdir %s', oDir); - }); - } - }); - -program.parse(process.argv); -``` - - An `Array` is used for the value of a variadic argument. 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('<cmd> [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. `<cmd>`) 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 <type> 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'); - -program - .version('0.1.0') - .option('-f, --foo', 'enable some foo') - .option('-b, --bar', 'enable some bar') - .option('-B, --baz', 'enable some baz'); - -// must be before .parse() since -// node's emit() is immediate - -program.on('--help', function(){ - console.log('') - console.log('Examples:'); - 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('<script>alert("xss");</script>'); -``` - -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:<script>alert(/xss/);</script> -``` - -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:<script>alert(/xss/);</script> -``` - -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:<!-- something --> 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 = '<div a="1" b="2" data-a="3" data-b="4">hello</div>';
