If you don't mind changing your buffer, create a custom filterwritepre command that filters your buffer through tr (works only on unix or within a cygwin environment, e.g. something like this: fu! ConvertLower() %!tr "[A-Z]" "[a-z]" endfu aug MyDiff au! au FilterWritePre file* call ConvertLower() aug end Adjust the pattern file* to your filenames. If you are on windows, replace the tr part by :%s/.*/\L&/ Best, Christian -- Wir sind begieriger, fremde Menschen zu observieren und auszuspähen als tägliche und nahe. -- Jean Paul -- -- You received this message from the "vim_use" maillist.
