Suppose I want to filter foo.doc through antiword or bar.pdf
through pdftk. (Both of these are tricks that I have learned only
recently.) It seems simple enough. For example, vim tip #790,
http://www.vim.org/tips/tip.php?tip_id=790
suggests
autocmd BufReadPost *.doc silent %!/usr/bin/antiword '%'
(along with an autocmd or two to set 'ro' and--I am not sure
why--'nohlsearch'. I tried this, and it worked pretty well until I
tried it on (ugh) file\ with\ spaces.doc . So now I have
autocmd BufReadPost,FileReadPost *.doc execute '%!antiword' escape(@%, ' ')
IIUC, all the details like error handling and escaping spaces in
file names are already handled by autoload/gzip.vim . Before settling
on the above, I tried
" autocmd BufReadPost,FileReadPost *.doc call gzip#read("antiword")
but, as you can see, I commented it out because it did not work. I
apologize: I have not tried as hard as I might to get it to work. Does
anyone else know how to do this? Or does autoload/gzip.vim need to be
made more flexible before it can be applied to other filters (antiword,
pdftk for example) as well as gzip?
