这是功能程序不能没有的功能。你可以试试yargs。
npm install --save-dev yargs您可以像这样使用它:
gulp mytask - -production --test 1234在代码中,例如:
var argv = require('yargs')。argv; var isProduction =(argv.production === undefined)?假:真;为了您的理解:
> gulp watch console.log(argv.production === undefined); < - true console.log(argv.test === undefined); < - true > gulp watch --production console.log(argv.production === undefined); < - false console.log(argv.production); < - true console.log(argv.test === undefined); < - true console.log(argv.test); < - undefined > gulp手表--production --test 1234 console.log(argv.production === undefined); < - false console.log(argv.production); < - true console.log(argv.test === undefined); < - false console.log(argv.test); < - 1234希望您可以从这里购买。
还有另一个可以使用的插件,minimist。还有另外一篇帖子,里面有很多yargs和minimist的例子:(是否可以通过一个标志让Gulp让它以不同的方式运行任务? )
Normally we can run gulp task from console via something like gulp mytask. Is there anyway that I can pass in parameter to gulp task? If possible, please show example how it can be done.
解决方案It's a feature programs cannot stay without. You can try yargs.
npm install --save-dev yargsYou can use it like this:
gulp mytask --production --test 1234In the code, for example:
var argv = require('yargs').argv; var isProduction = (argv.production === undefined) ? false : true;For your understanding:
> gulp watch console.log(argv.production === undefined); <-- true console.log(argv.test === undefined); <-- true > gulp watch --production console.log(argv.production === undefined); <-- false console.log(argv.production); <-- true console.log(argv.test === undefined); <-- true console.log(argv.test); <-- undefined > gulp watch --production --test 1234 console.log(argv.production === undefined); <-- false console.log(argv.production); <-- true console.log(argv.test === undefined); <-- false console.log(argv.test); <-- 1234Hope you can take it from here.
There's another plugin that you can use, minimist. There's another post where there's good examples for both yargs and minimist: (Is it possible to pass a flag to Gulp to have it run tasks in different ways?)
