vim acting strange

So i found some helpful vim-hints on a page. Mostly stuff for .vimrc

I found out that i didn't have a .vimrc, so i made one, with this in it:

Code:

set nocompatible

syntax on

set pastetoggle=<F10>

set showmatch

set ignorecase

set incsearch



" autocomplete

function! CleverTab()

  if strpart( getline('.'), 0, col('.')-1 ) =~ '^s*$'

      return "<Tab>"

  else

      return "<C-N>"

endfunction

inoremap <Tab> <C-R>=CleverTab()<CR>

i am not sure how the pastegoogle is supposed to act, so i don't know if that's failing. I did notice that "syntax on" (highlighting) isn't working, at all, neither is the autocomplete-script at the bottom.

I write, for example, this:

Code:

$hi

$bye

$night

Then this happens when i write $ni hit tab:

Code:

$ni<C-N>

Another example:

Code:

*you

sme

^us

some words with tab, this is what i get:

Code:

^u<C-N>

*y<C-N>

s<Tab>

- Does anyone know why the highlighting and the tabcomplete-script is failing?

EDIT:Whenever i press tab, i get "<C-N>". The text i found (in norwegian, or else i would have linked to it) said that i would be able to "tab" as normal..

Re: vim acting strange

Code:

" autocomplete

function! CleverTab()

  if strpart( getline('.'), 0, col('.')-1 ) =~ '^s*$'

      return "<Tab>"

  else

      return "<C-N>"

endfunction

inoremap <Tab> <C-R>=CleverTab()<CR>

The s in ^s*$ needs to be \s, <Tab> needs to be \<Tab>, <C-N> needs to be \<C-N> -- ie. in all three cases you need a real backslash. This tells vim that the five characters you're typing out as "<Tab>", for instance, need to be interpreted as a tab (not as the five literal characters).

In vim, :help completion will give you details (including the code-snippet above).

:help paste or :help pastetoggle

Did you just start typing in a fresh vim window or did you open a file? vim needs the file extension (or some pattern in the filename) to know what kind of file it is and which syntax-highlighting "kit" it needs to use. So if you ask vim to open foo.sh or foo.pl which contains your code it should do the highlighting appropriately. Or pick Syntax->Show Filetypes from the menu, and then whichever type you want.

Look at the syn*.vim and filetype.vim files in your vim installation if you want to see how all this is done (most likely in /usr/share/vim/...)

I tried to open/make foo.cpp - no colors though =\

I just copied .vimrc from my friends box, but the highlighting still don't work..

I think vim by default does not associate .cpp with C++. .C is C++, .c is C (as far as vim knows -- or at least as far as vim knows as far as I know :)). You can change what it thinks is a C++ file either in /usr/share/vim/filetype* or in your .vimrc Or try .sh or .pl, I know it recognizes those.

AFAIK, vim does take C++ by default. And .sh didn't work either. Thanks for trying to help, though :-)

One last idea: is this a nonstandard install at all? In vim, what does your $VIM variable contain? (:echo $VIM) $VIM/vim*/ should contain your syntax and other files. If it doesn't, that could be the problem. You might be able to reset $VIM in your .vimrc but I'm not sure about that.

I get this: /usr/share/vim

and about the install: I installed vim with apt-get ..
