gulp.src是做什么的？

Question

Im trying to use gulp prompt :

gulp.src('test.js')
    .pipe(prompt.prompt({
        type: 'input',
        name: 'task',
        message: 'Which task would you like to run?'
    }, function(res){
        //value is in res.task (the name option gives the key) 
 }));

Im confused to actually what gulp.src is for? I don't have a src I just want to prompt the user for an input.

gulp.src creates the stream of source files to perform the 'piped' operations on. In your example you're asking for a task to perform, which means you're asking what task to perform on the file test.js .

If you want to ask what task to perform, and then run one or more gulp tasks I think you'll need to write a plain old nodejs application that asks for the input and then start the gulp [name of task] from there.
