vim to remember the last location


I tried out vi on ubuntu 8.04 and fedora 10, but don't seem to able to
fix the "return the previous cursor position" when i reopen a file.

Tried out google suggestions but they are not working.

Quote:

augroup JumpCursorOnEdit
au!
autocmd BufReadPost *
\ if expand("<afile>:h") !=? $TEMP |
\ if line("'\"") > 1 && line("'\"") <= line("$") |
\ let JumpCursorOnEdit_foo = line("'\"") |
\ let b:doopenfold = 1 |
\ if (foldlevel(JumpCursorOnEdit_foo) > foldlevel(JumpCursorOnEdit_foo - 1)) |
\ let JumpCursorOnEdit_foo = JumpCursorOnEdit_foo - 1 |
\ let b:doopenfold = 2 |
\ endif |
\ exe JumpCursorOnEdit_foo |
\ endif |
\ endif
" Need to postpone using "zv" until after reading the modelines.
autocmd BufWinEnter *
\ if exists("b:doopenfold") |
\ exe "normal zv" |
\ if(b:doopenfold > 1) |
\ exe "+".1 |
\ endif |
\ unlet b:doopenfold |
\ endif
augroup END
or

Strange enough, the vim that comes with CentOS is working very well (comes even with nice text highlighting when I open a Fortran90 file). But I don't find .vimrc file that I can recycle.

Looks like I have a case where the old horse is better than the new ones.

Cheers.

After installing vim-enhanced
things are working fine on f10.

Quote:
[ckgan@f10-32-dell tex]$ rpm -qva | grep vim
vim-enhanced-7.2.148-1.fc10.i386
vim-minimal-7.2.025-2.fc10.i386
vim-common-7.2.148-1.fc10.i386
I really like to ditch vi since it confuses me quite a bit with vim.

Quote:
[ckgan@f10-32-dell tex]$ which vi
/bin/vi
[ckgan@f10-32-dell tex]$ which vim
/usr/bin/vim

CentOS folks are a bit more humane:

Quote:
[root@centos52-64-fuj profile.d]# cat /etc/profile.d/vim.sh
if [ -n "$BASH_VERSION" -o -n "$KSH_VERSION" -o -n "$ZSH_VERSION" ]; then
[ -x /usr/bin/id ] || return
[ `/usr/bin/id -u` -le 100 ] && return
# for bash and zsh, only if no alias is already set
alias vi >/dev/null 2>&1 || alias vi=vim
fi

ubuntu's vim is still no cooperating, its behavior is still like
standard vi.

I did

sudo apt-get install vim vim-common vim-gnome vim-gui-common vim-runtime


but still there is no progress.

Can't believe ubuntu is that unfriendly towards me !!

why is ubuntu so unclean? (or whatever you might call it)

After I purge and autoremove vim (hoping that i can get the latest vim),
the vim is still executable in the system.

Found this in
https://bugs.launchpad.net/ubuntu/+s...vim/+bug/69611


Quote:



Binary package hint: vim-common

in /etc/vim/vimrc

the commented lines that allow one to jump to the last position when reopening a file are incorrect. It doesn't act properly if a user remaps g in their .vimrc . It needs an ! after the normal. It should read:

" Uncomment the following to have Vim jump to the last position when
" reopening a file
"if has("autocmd")
" au BufReadPost * if line("'\"") > 0 && line("'\"") <= line("$")
" \| exe "normal! g'\"" | endif
"endif

Notice the ! after normal, that needs to be added so that it doesn't remap the g. Obviously this is only a problem if someone uncomments those lines, and has g remapped in their .vimrc (or vimrc.local in my case).

to reproduce, uncomment those lines in /etc/vim/vimrc and add
noremap g >>j
to /etc/vim/vimrc.local
After doing what this says, I still have

Quote:
ckgan@ubuntu804-32-dell:~$ !v
vim
Error detected while processing /usr/share/vim/vimrc:
line 30:
E10: \ should be followed by /, ? or &
Press ENTER or type command to continue
I think I run of luck today. I am starting to doubt the friendliness of
you-know-what...

Solved.. borrow /etc/vimrc of CentOS5.2 and figure out to put everything
in one line to avoid backslash. And it works now.

Quote:
if has("autocmd")
" When editing a file, always jump to the last cursor position
autocmd BufReadPost * if line("'\"") > 0 && line ("'\"") <= line("$") | exe "normal! g'\"" | endif
endif
what a pain!
