    vim: Several questions [title edited]

    Hi,

    Sorry for a question that my friend Google might resolve, but I am behind a firewall and all is hard now

    When I jump between files in vi (:n#), is it then possible to leave (and return to) a file where I haven't saved changes (w). As it seems now (vi and vim) I must save changes before leaving a file for the next.

    Thanks

    Ctrl + X and 'N' to say no to changes.

    Doesn't that work?

    Re: vi(m): Edit multiple files without saving

    What I would like to do is to keep the changes until a come back to the file again, but I do not want to write them to disk. maybe that is not possible.

    When I try the ctrl/x command in vim command-mode I just hear a "click", it seems not to be allowed.

    Sorry for adding one question: Syntax highlighting works for C, but not for php. Is that possible to cure? (And preferably also JavaScript)

    /add: I think I found the answer to the added question: SET SYN=PHP seems to do it.


    Thanks

    I usually don't find it problematic to save when switching files, though I have noticed that if you use split window (with :split or :vsplit), you don't need to save while moving between the open windows. To move between the open windows, use ^W<direction>.

    Re: vi(m): Edit multiple files without saving

    yes, the inability to save is not a big issue. I used CLI-editors a lot in the 70's and 80's and now I find I am returning more and more to vi. So I have better try finding a quick and pleasant working environment.

    I haven't yet found a color scheme I quite like. I am getting a little older and should wear reading glasses, but I don't. I prefer light background, but I think that somehow makes the text not stand out enough.

    Here the text comes out better, but I would like to try the background lighter
    :highlight Normal ctermfg=grey ctermbg=darkblue
    Changing the command to lightblue does not make a difference.

    All the colorschemes I can find on the Internet do not seem to be installed in the verison I am running.

    How do I install colorschemes. (In the 80's we only had b/w )
    And how do I find which ones are installed. (:colorscheme does not work) (OK I found the reply to this one: colorscheme<space><tab>)

    Re: vi(m): Edit multiple files without saving

    It only seems possible to set color for the first file edited.

    If I open more files by
    :n myfile
    they all come out in black background.

    For the first file I edit I can change colors with
    :colo desert
    :colo morning

    But this does not work for other files opened with :n

    It looks like a bug, but considering the qualities of vi(m), I guess I just haven't found out how to do it yet.

    Re: vi(m): Edit multiple files without saving

    this may or may not be relevant...
    :vsp <path/to/file>

    splits the window vertically
    use ctrl+w to switch between files to edit.
    :qall to quit all.
    or :q! to quit each window.

    i hope thats what you meant?

    Re: vi(m): Edit multiple files without saving

    enter this (or just put in your .vimrc):

    Code:
    set hidden
    then use :e to edit new files rather than :n

    also, to have your colours persist across sessions, put them in your .vimrc. My personal favourite is darkspectrum, which works great in the terminal with this plugin.

    Thank you everyone for good ideas.

    Thank you Krazyd, you gave the solution to my original question. I tried your advice, it works. (I yet don't understand how, though. ) There is always a solution in vim.

    I will check more about colorschemes and come back. Now time to sleep in the region I reside

    Thanks guys.

    In vim, if you want to be able to temporarily leave a modified buffer in order to visit another file, you need to enable this feature with
    Code:
     :set hidden
    which allows modified buffers to be hidden.
