将参数传递给Gulp任务 [英] Pass Parameter to Gulp Task
问题描述
gulp mytask
的方式从控制台运行gulp任务。无论如何,我可以通过参数传递给吞噬任务吗?如果可能的话,请展示如何完成它。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.
It's a feature programs cannot stay without. You can try yargs.
npm install --save-dev yargs
You can use it like this:
gulp mytask --production --test 1234
In 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); <-- 1234
Hope 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?)
