How to list content of nested jars

Question

Suppose, I have a .jar file a.jar, which I can view via vim a.jar, giving a list of the content like:

a1.txt
a2.txt
b.jar

I can press enter and load the content of each file; however, for .jars inside this archive, I am more interested in the content listing than the binary content. In this case, I want enter to show me a similar view of b.jar, rather than it's binary content.

In other words, how can I show list of files of nested .jar files in vim?

Answer 1

.jar files are essentially zip files (you'll probably have noticed the " zip.vim version vxx banner at the top of the buffer). There are a few plugins which aim to help open nested zips, so you could try one (vim-rzip, for example) as a possible fix.
