Passing a string as a parameter to a gulp task

Question

  var gulp = require("grunt");

    gulp.task('taskName', function(strng) {
        console.log(strng);
    });

Generally, the gulp file is run as "gulp taskName" I want to know how to pass "strng" with the taskName in command line as a parameter

as i recall "gulp taskName:strng" its not an argument its calling subtask "strng" — Vova Bilyachat, Mar 21 '16 at 10:28
without using yargs, cant we do it? How we will pass asrgument to the function taskName? — Surya, Mar 21 '16 at 10:29
yea, even I was thinking of the same. Let me be brief about my use case. I have a string which i need to manipulate as a valid string using a function with Gulp. I have a function, say, "function(string) { }". Using gulp gulptask --strng value...... How will I find out which is my string and value. Is is something like "--options 3". If so how may I proceed with such a use case. — Surya, Mar 23 '16 at 04:29

You may consider using yargs

In your gulpfile var args = require('yargs').argv;

In your command line $ gulp taskName --yourparamvariable=bar

To access the paramerter you've sent from your command line args.yourparamvariable

I've used this technique in some of my gulp tasks and it works really well. – reduckted Mar 28 '16 at 04:16
