Specify file to test from the command line

How can i specify a file I would like to test from the the command line?

@diomededavid what do you mean?

I guess you want to edit/comment some of the lines in gulpfile.js?

@diomededavid I'm sure you've found this by now, but you can use yargs to pass command-line options to your gulp tasks. For example,

$ gulp send --to me@mydomain.com --message email.html

where send is the task defined and configured for sending an email, something like:

function send () {
	var config = {...} // where ... is your valid SMTP (or other) config
	var config.to = yargs.argv.to;
	var message = yargs.argv.message;

	return gulp.src(message)
		.pipe(gulp_mail(config))
		.pipe(gulp.dest('dist'));
}

You probably will want to define defaults and check for values / errors, but that's basically that.

@justin713 Thanks. I did get it to do the test, and the entire script runs using: "gulp mail --message filename.html". I receive the email test, but all the the inlined CSS get stripped out.

I am using Foundation for emails. Here is the function I am using.

`
function mail() {
var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;
var message = yargs.argv.message;

if (EMAIL) {
CONFIG.mail.to = [EMAIL];
}

return gulp.src('dist/**/' + message)
.pipe($.if(!!awsURL, $.replace(/=('|")(/?assets/img)/g, "=$1"+ awsURL)))
.pipe($.mail(CONFIG.mail))
.pipe(gulp.dest('dist'));
}`

@diomededavid The only thing I can recommend is to check that the file(s) being sourced by the mail() function are properly inlined. gulp-mail itself doesn't do any transformations to the source, so it's more likely to be a problem with the gulp task responsible for doing the inlining.

@diomededavid — found this via a Google Search as I was trying to do this as well. So here is what I did to handle only sending to a specific template, for reference you'll be editing the gulpfile.babel.js.

Put this below the PRODUCTION + EMAIL towards the top:

const TEMPLATE = yargs.argv.template;

Replace your current function mail() with the following:

// Send either a specified template to email for testing or just send them all.
// If no AWS creds then do not replace img urls.
// Ex: npm run mail -- --template filename.html
function mail() {
  var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;
  if (TEMPLATE) {
    var mailSource = 'dist/**/' + TEMPLATE;
  } else {
    var mailSource = 'dist/**/*.html';
  }

  if (EMAIL) {
    CONFIG.mail.to = [EMAIL];
  }

  return gulp.src(mailSource)
    .pipe($.if(!!awsURL, $.replace(/=('|")(\/?assets\/img)/g, "=$1"+ awsURL)))
    .pipe($.mail(CONFIG.mail))
    .pipe(gulp.dest('dist'));
}

Then to run the new script with your specific template you'd do npm run mail -- --template filename.html — I hope this helps you or anybody else who is trying to do this too as well.
