The currently used version of Uglify mangles vars to letters that cause errors in Safari #623

I am prepending 6 or 7 vendor libraries to my js file using CodeKit's in-file prepends—minifying the resulting js with CodeKit.

I'm seeing this error in Safari—preventing the page from fully loading: app.min.js:5SyntaxError: Cannot declare a parameter named 'i' as it shadows the name of a strict mode function.

I'm pretty sure this is the same issue documented here: mishoo/UglifyJS2#179

It appears this was fixed in an earlier version of Uglify than what I see is being used in CodeKit's about page - Uglify 2.6.2

So, I am not really sure what the problem is, actually.

As a temporary solution, is there any way I can set this to avoid using specific vars when minifying (while still minifying)?

I'm currently using CodeKit version 2.8 (19127)

Interesting. I'll have to update the Uglify version bundled in CodeKit. I'll try to do that tonight.

binomialstew commented 7 years ago

That would be awesome, but I am confused because the version of Uglify used by CodeKit seems to be more recent than the versions of Uglify with the bug I linked.

binomialstew commented 7 years ago

I can confirm the latest version of Uglify (2.7.3) mangles with no Safari errors.

binomialstew commented 7 years ago

I just updated to CodeKit 3.0.3 and can confirm that this is still an issue.

bdkjones commented 7 years ago

Mmm... 3.0.3 has Uglify 2.7.3. If there's still a problem, please provide an exact example and files to reproduce. Those will likely need to go to the Uglify team.

binomialstew commented 7 years ago

Yes, you are right. My apologies. The error I am seeing now has to do with a prepended library that is misusing "delete".

What threw me off is when I mangle and compress using uglify via terminal, "strict mode" is not prepended to my output file, but when using CodeKit's uglify, it is. Do you know why this would be?
