是否有任何javascript minifiers保留换行符？

Question

Error reporting from the client that always reports an error on line 1 (because the file is minified) is not very useful. I'd like to minify my code while preserving line breaks so that I get meaningful line numbers.

Are there any javascript minifiers that have an option to preserve line breaks?

Answer 1

Take a look at closure compiler from Google with pretty print option enabled

There are also plenty of options if you use the command line tool.

Answer 2

I've been looking for the same thing and although I've not found exactly what I want, I've just seen that the (now deprecated) YUI Compressor has a --line-break 0 switch that causes a line break to be inserted after each semicolon. Since I was using YUI Compressor anyway, I think this will do for my debugging purposes.

Answer 3

I think this is it: https://developers.google.com/closure/compiler/docs/inspector

as Fabien said Closure compiler ... but after looking for this for third time I found out that Closure compiler can produce mapping file between optimized code and original source :)

you also are not limited to use the web service, you can download it as standalone app :)
