Greetings: The ":Man" command uses "cat" as the pager. This can result in troff errors showing up in the man page buffer. On Debian-based systems, you can see this with the following:
1. vim 2. :vsplit 3. * set width of window to ~70 cells 4. Open one of these pages... man keytool man nm-settings man readelf You can see that several errors show up (screenshot attached). Since these don't do the user any good, and the output is, usually still legible, we can silence them. This patch will silence these errors by sending them to /dev/null: diff --git a/runtime/ftplugin/man.vim b/runtime/ftplugin/man.vim index f627035eb..b5de1d60a 100644 --- a/runtime/ftplugin/man.vim +++ b/runtime/ftplugin/man.vim @@ -1,7 +1,7 @@ " Vim filetype plugin file " Language: man " Maintainer: SungHyun Nam <[email protected]> -" Last Change: 2020 Apr 13 +" Last Change: 2020 Apr 23 " To make the ":Man" command available before editing a manual page, source " this script from your startup vimrc file. @@ -205,11 +205,11 @@ func <SID>GetPage(cmdmods, ...) endif let env_cmd = s:env_has_u ?
