Re: [PATCH] fix man page viewing with man-db
Hello, I've also experienced man.vim crashing when $MANPAGER had been already defined to `col -b | vim -R -' in .bashrc. I took a look at the man.vim file and came up with the following idea. Instead of asking if $MANPAGER was defined, why not define it temporarily for the call. It's possible to do this via let tmp = tempname() let $MANWIDTH = tw ? tw : 80 let manpager = shellescape('less -s') Fixes problems when user has defined $MANPAGER silent execute !MANPAGER=.manpager. /usr/bin/man .args.| col -b .tmp silent execute pedit .tmp See the attachment for the complete reimplementation of GetPage(). I also wanted to fix a couple of subtle shortcomings of the original script. In my opinion, viewing man pages should mimic reading help pages which is already reflected nicely in the mappings C-] and C-t. However, it would also be nice to be able to double click the topics as one can do in help files. Man pages should also be closed when the last writable buffer is closed in the current tab page, as is the case with help files. Now the user is potentially left with two windows to the same shell script. The first was used to spawn a man page via LeaderK for example and the second appeared unintentionally when the user rewinded man pages one time too many. Finally, all man pages shouldn't be only 'readonly' but also 'nomodifiable'. All of these aspects are taken care of in the script you'll find in the attachment. I post it to your consideration.

[PATCH] fix man page viewing with man-db
Fedora 14 switched to man-db for handling man pages. Ubuntu has been using it for ages. On older versions of Fedora I was able to just add this to my .bashrc to have full man page functionality, (with drill down) using vim export MANPAGER='bash -c vim -MRn -c \set ft=man nomod nolist nospell nonu\ \ -c \nm q :qa!CR\ -c \nm end G\ -c \nm home gg\/dev/tty (col -b)' (if pasting that in a terminal make sure to \ the ! in the second line) The above works fine for man-db too, except when using Ctrl-[ to drill down into sub man pages. In that case man-db will run the output through $MANPAGER again, even though the output is not a tty. That would cause various vim errors and hangups. I was able to work around this in my ~/.vimrc with: augroup man au!
