STDIN parsing errors

[arnaudlimbourg]

I run into a strange error when trying to uglify jquery@1.8.3 with uglify-js@2.2.2 :

$ cat jquery-1.8.3.js | uglifyjs
WARN: ERROR: Unexpected token eof «undefined», expected punc «)» [-:2421,35]

But if I run it like this:

 $ uglifyjs jquery.js

It only happens with this particular file, backbone or underscore, or even my own code doesn't exhibit this issue.

Your example code uses two different files...

Works for me...

I had copy/pasted and removed some info. I started from scratch and I still have the error

Running the following command does output any error

$ /usr/bin/env uglifyjs jquery-1.8.3.js

This will hopefully help and make the issue clearer.

I may be doing something wrong but I get this result consistently.

@rvanvelzen sorry for messing up the copy/paste, it was indeed the same file.

I get this too. It seems compiling from stdin is completely broken.

$ cat jquery.js | uglifyjs
