I have configured vim to automatically decompile ".class" files similar to the instructions in: http://vim.wikia.com/wiki/VimTip54.

I have made a minor change to use cfr_0_115 as below:

augr class
au!
au bufreadpost,filereadpost *.class silent %!java -jar /blah/cfr_0_115.jar %
au bufreadpost,filereadpost *.class set readonly
au bufreadpost,filereadpost *.class set ft=java
au bufreadpost,filereadpost *.class silent normal gg=G
au bufreadpost,filereadpost *.class set nomodified
augr END

This works fine when opening files from the shell.

Sometimes I work with JAR files and would like to achieve the following workflow:

1. :Explore (and navigate to the JAR file)
2. View the JAR file and select a Class
3. When this Class is opened, it should be ran through CFR.

Currently, when I get to step "3" the class is not decompiled for viewing. I'd love to know how I can get the class file from a JAR opened 'through' the class decompiler.

Edit 1 - With Vim logging enabled, when I open a class file that is NOT within a JAR file, I see Executing BufRead Auto commands for "*.class include the command I wish to run. However, when I open the class file from within a jar, I do not see the command in the logs.

Edit 2 - Relevant log entries when opening a JAR:

Executing BufReadCmd Auto commands for "zipfile:*/*"
autocommand call zip#Read(expand("<amatch>"), 1)

Calling shell to execute: "(unzip -p -- '/blah/original-httpclienttest-1.0.jar' 'com/atlassianlabs/sslclient/Main.class') >/var/folders/ys/18xytj217f749_vx7rhs4t7w0000gp/T/vwqRYKe/1 2>&1"
chdir(zipfile:/blah/original-httpclienttest-1.0.jar::com/)
fchdir() to previous dir
Reading viminfo file "/blah/.viminfo" marks

and later:

Executing BufRead Auto commands for "*.class"
autocommand setf stata

However when I open a class file by navigating to it directly with the file explore (:Explore) I see:

Executing BufRead Auto commands for "*.class"
autocommand silent %!java -jar /blah/cfr_0_115.jar

Follow-up

I don't know why the autocmd's that exist are not getting picked up when opening from a JAR, because VIM is actually running some autocmd, just not the one I want and "autocommand setf stata" is not even present when opening a class. I'm blocked in terms of how to debug this further.

More Follow-up

I got this working to some extent by adding a function to the filetype.vim file on class files. However, vim reports the file name in the format: ZIPFILEPATH::PATHTOCLASS in the JAR.. I was hoping it would send though the temp file path instead.
