Also, how can I go about finding out what a sequence means? Lets say I see a command
au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif
and I want to find out what some sequences mean? Google does not allow searching for symbols, it just ignores them, so I rarely find anything.
if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif`
This is if else statement which can be written as follows:
if line("'\"") > 1 && line("'\"") <= line("$")
exe "normal! g'\""
endif`
The meaning of au BufReadPost can be found here: http://vimdoc.sourceforge.net/htmldoc/autocmd.html#BufReadPost
g'\" means go to the mark ", but don't change the jumplist when jumping within the current buffer as pointed out here: https://vimhelp.appspot.com/motion.txt.html#mark-motions
Here the mark " indicates: jump to position where last exited current buffer
If you ran g'" in normal mode in VIM it would work fine, but you are running a normal mode command in Exmode, which is why you need to use the \ to escape the ".
if else but you do realise you didn't actually answer the question specifically asked in the title, yes? The What does g'\“” mean? one. It would probably be a more complete answer if you covered that.
