I'm not really sure what you're trying to do - the example appears to start vim on a file and then wait for it to exit, with nothing else happening. Are you interacting with vim manually in the meantime?
Regardless, I bet the issue is that vim does not save the data to the same file - it saves to a temp file and then atomically renames it over the original. This means your fd is referring to the old file that is now unlinked, and not the new contents. //jb > On 21 Aug 2017, at 06:50, Alexandru Bonini <boninialexan...@gmail.com> wrote: > > https://play.golang.org/p/_rudr2_Vyc > > I don't understand why any change done via vim is not reflected by b.String(). > I can see the changes in the tempfile. > Any help is appreciated. > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
