Minifying angular-bootstrap-datetimepicker fails with gulp-uglify

[henrikthorin]

Since your last update where you have removed all semicolons in your code, our gulp-minify fails resulting in a corrupt minified js file.

Please advice us what do to.
We will revert to 1.0.1 until we have a working solution.

We're having this issue as well!

Can you create a Reduced Test Case/example for this problem?

Perhaps a minimal gibhub project that shows the problem.

You MUST have a recreation or I cannot work on this issue.

Absolutely running into this issue.

Still checking on a solution...

When concatenating the files together, adding in a semicolon between the file solves the issue. I've manually tested this several different ways, using multiple semicolons and various combinations of \r, \n, and ; and it always works after minification.

gulp.task('minify', function () {
  var destination = path.join(__dirname, 'build', 'js')
  return gulp.src(paths.src)
    .pipe(concat('datetimepicker.all.min.js', {newLine: ';'}))
    .pipe(uglify())
    .pipe(gulp.dest(destination))
});

This is the line that solves the problem .pipe(concat('datetimepicker.all.js', {newLine: ';'}))

This also works - changing the order of the operations and uglify first, then concatenate will put each file on its own line separated by \n. I guess is just depends on which output you like.

gulp.task('minify', function () {
  var destination = path.join(__dirname, 'build', 'js')
  return gulp.src(paths.src)
    .pipe(uglify())
    .pipe(concat('datetimepicker.all.min.js'))
    .pipe(gulp.dest(destination))
});

I forgot one very important rule about ASI in JavaScript. Never start a line with (, [, or `

I'll release a fix shortly.

For the following releases (not this one!), I will update the tests so they also run against the minified code so I can be 100% sure the code will minifiy correctly before release.
