Re: double the columns in vim on vertical split

Kamaraju,

  I use a 'function' to expand/contract window size when I turn on or off 'tags-list' window for my coding sessions.

I'm sure I lifted this idea from a google-search on this need.  

Copying in the code in below.  Use it as a guide if you want, and modify to fit your need.  

I have this in my .vimrc file.

---Dave.

" ====================

" TAG-LIST tool.

" ====================

if split( system( "ps -o command= -p " . getpid() ) )[0] == "gvim"

    let s:tagson = 0

    function! MyTagListFunction()

        if s:tagson == 0 

            "Tags going on - increase window size

            set columns+=30

            let s:tagson = 1

        else

            "Tags going off - reduce window size

            set columns-=30

            let s:tagson = 0

        endif

        :Tlist

    endfunction

  if version >= 600 

      amenu icon=taglist.bmp ToolBar.taglist :call MyTagListFunction()<CR>

      tmenu ToolBar.taglist TAG-LIST 

  endif 

endif

Can you explain why you need columns setting? What is your operating system? I see on Windows whole gVim program gets this size (which is little bit useless) and on vim for Linux it gets text truncated at exactly 80 characters.

Maybe you are looking for a setting like:
set textwidth 80

The above command with truncate whole words in new rows if passing 80 characters. It also preserves the 80 characters if you add new window with: vsp command.

If using textwidth command you have to delete "set columns=80" from your ~/.gvimrc file and restart Vim.
