I use CVS to sync my config files between different PCs, including my $HOME/.vim folder.
But there is a problem. CVS likes to leave old copies of files in .vim/plugin/CVS/Base/ and Vim thinks it should load these files. I want vim to ignore them!
You can use SourceCmd for this case:
augroup ForbidCVS
autocmd!
autocmd SourceCmd */CVS/* :" Do nothing
augroup END
At the bottom of $HOME/.vimrc add:
" Disable normal auto-loading of plugins
set noloadplugins
" Now load just the plugins we want
runtime! plugin/*.vim
This differs from the default behaviour which usually loads scripts from plugin/ and all its subfolders. I suspect most users do not make sub-folders. For users that do, this won't work!
An easy way to share your .vim and .vimrc across multiple computers is to put both on dropbox and symlink them to the $HOME directory of each computer you work on. No CVS required, and any change you make to your .vimrc for example, is immediately available to all other computers.
Another cool tip is to use the vim gsession plugin to create global session files stored to your .vim directory. So if you create a session on one computer, it is also available to all the others.

I have created my own colorscheme, and would like to set it as my default in my ~/.vimrc file.
My problem being, (as I understand it), I am on my school's linux server (Ubuntu 14.04), where many hundreds of students have accounts.
I have read into this, and as I see it, I cannot change the colorscheme because the directory that vim is searching through is /usr/share/vim/vim74/colors/, which I do not have access to.
How might I go about adding my colorscheme as default for my acount?
Perhaps editing the ~/.vimrc file to search for a file within my home directory (~/.vim/colors/scheme.vim)? I have tried that, but could not make any progress.
Am I out of luck on this?
Thanks
The standard location is:
~/.vim/colors/colorschemename.vim
and you call it in your ~/.vimrc like this:
colorscheme colorschemename
NEVER do anything in /usr/share/vim/ unless you are the administrator of a multi-user system and know what you are doing.
I think if you have enough space, you can copy whole /usr/share/vim/vim74 to your local directory and then set $VIMRUNTIME environment variable to this local directory.
Other way is to put source $HOME/.vim/colors/scheme.vim in your .vimrc .
How can I change the location of the .vim folder and the .vimrc file so that I can use two (or more) independent versions of vim? Is there a way to configure that while compiling vim from source? (maybe an entry in the feature.h?)
Why do I want to do such a thing?:
I have to work on project that use python2 as well as python3, therefore I want to have two independent vim setups with different plugins, configurations etc. Moreover, one version has to be compiled with +python, the other with +python3.
You can influence which ~/.vimrc is used via the -u vimrc-file command-line argument. Since this is the first initialization, you can then influence from where plugins are loaded (i.e. the .vim location) by modifying 'runtimepath' in there.
Note that for editing Python files of different versions, those settings (like indent, completion sources, etc.) are taken from filetype plugins which are sourced for every buffer separately, so it should be possible to even edit both Python 2 and 3 in the same Vim instance. (Unless you have some badly written plugins that define global stuff.) So for that, some sort of per-buffer configuration (some :autocmds on the project path, or some more elaborate solution (search for localrc plugins or questions about project vimrc here) might suffice already.
Also note that when the Python interpreter (which you'd only need for Python-based plugins and some interactive :py commands, not for editing Python) is compiled in with dynamic linking (which is the default at least on Windows), you can have both Python 2 and 3 support in the same Vim binary.
I think the easiest solution would be just to let pathogen handle your runtimepath for you.
pathogen#infect() can take paths that specify different directories that you can use for your bundle directory.
So if your .vim directory would look like this
.vim/
autoload/
pathogen.vim
bundle_python2/
<plugins>
bundle_python3/
<other plugins>
Then inside one of your vimrc for python 2 specific stuff you would have
call pathogen#infect('bundle_python2/{}')
and for python 3 specific stuff you would have
call pathogen#infect('bundle_python3/{}')
Since each plugin folder is really just a .vim folder you can place your python specific configuration stuff in a folder of the corresponding bundle and pretend its a .vim.
This structure also has the added benefit that you can change both configurations at the same time if you feel like it by putting common stuff in .vim normally.
You can also pass multiple bundle directories if you feel like to pathogen so you can have plugins that are shared without duplicating files. You just do this by passing multiple paths to pathogen#infect('bundle/{}', 'bundle_python3/{}')
After this is all done you can just create aliases for vim to call the correct vimrc file.
I found a way to do this!
You can just create a fake $HOME, whose contents are simply the .vim folder and .vimrc. Then, when running vim, set the HOME environment variable to that folder, and change it back on VimEnter.
Run vim with:
OLD_HOME="$HOME" HOME="$FAKE_HOME" vim
Add this to your .vimrc:
autocmd VimEnter * let $HOME = $OLD_HOME
On Windows you can use
let $HOME = $HOMEDRIVE.$HOMEPATH
insetead, no need to store the old home.
This works, but if you use $HOME inside your vimrc or any plugins will see the old value, it might affect them somehow. So far I haven't seen it.
Note: I don't really recommend doing this.
If you really really want to recompile vim so that it uses a different vimrc and different configuration directory take a look at src/feature.h
Search this file for USR_VIMRC_FILE. Uncomment it and place the name of your vimrc here. This will change the defualt vimrc file.
So it should look something like this
#define USR_VIMRC_FILE "~/path/to/vimrc"
Inside src/os_unix.h or src/os_mac.h and search for DFLT_RUNTIMEPATH. Change all instance of ~/.vim to whatever folder you want. This should set the default runtime path that vim searches for settings.
Is there a way to unmap mappings set by plugins? I'm currently calling exe ":mapclear" before my custom mappings in my .vimrc file, but the plugin files appear to be sourced after the vimrc file does. I have to resource my vimrc file again for it to work as expected.
I'm using Pathogen for sourcing plugins, which are all contained in my ~/.vim/bundle folder.
You could write the part with the mappings in your .vimrc in another file, say MyMaps.vim, and put this file in ~/.vim/after/plugin/.
This should make your maps the default ones
Look also at the documentation of the plugins setting the mappings, some of them
allow you redifine or deactivate the default mappings.
While snooping around my various plugins, I've found a kind of solution.
Unfortunately, a lot of the plugins (such as vim-surround, and vim-align, which in turn uses cecutil) add commands to my mapleader. Since I realised there actually are some key mappings from plugins I do use, I decided to set my mapleader back to its default (backslash) at the end of my vimrc file to prevent overlap.
The only problem I came across were mappings that were set in functions. When using au FileType html call ConfigHTML(), for example, the ConfigHTML() function would actually get called after the mapleader is set back to backslash.
Is there a way to disable .swp files creation in vim? or at least create them all in one place so I can find and delete them easily.
I find them especially annoying when I copy the parent directory while editing at the same time. Of course I know that I can use find -exec to find and delete them. But I want a more practical solution.
To disable swap files from within vim, type
:set noswapfile
To disable swap files permanently, add the below to your ~/.vimrc file
set noswapfile
For more details see the Vim docs on swapfile
Set the following variables in .vimrc or /etc/vimrc to make vim put swap, backup and undo files in a special location instead of the working directory of the file being edited:
set backupdir=~/.vim/backup//
set directory=~/.vim/swap//
set undodir=~/.vim/undo//
Using double trailing slashes in the path tells vim to enable a feature where it avoids name collisions. For example, if you edit a file in one location and another file in another location and both files have the same name, you don't want a name collision to occur in ~/.vim/swap/. If you specify ~/.vim/swap// with two trailing slashes vim will create swap files using the whole path of the files being edited to avoid collisions (slashes in the file's path will be replaced by percent symbol %).
For example, if you edit /path/one/foobar.txt and /path/two/foobar.txt, then you will see two swap files in ~/.vim/swap/ that are named %path%one%foobar.txt and %path%two%foobar.txt, respectively.
I found the answer here:
vim -n <file>
opens file without swapfile.
In addition:
set dir=/tmp
in .vimrc creates the swapfiles in /tmp.
here are my personal ~/.vimrc backup settings
" backup to ~/.tmp
set backup
set backupdir=~/.vim-tmp,~/.tmp,~/tmp,/var/tmp,/tmp
set backupskip=/tmp/*,/private/tmp/*
set directory=~/.vim-tmp,~/.tmp,~/tmp,/var/tmp,/tmp
set writebackup
I agree with those who question why vim needs all this 'disaster recovery' stuff when no other text editors bother with it. I don't want vim creating ANY extra files in the edited file's directory when I'm editing it, thank you very much. To that end, I have this in my _vimrc to disable swap files, and move irritating 'backup' files to the Temp dir:
" Uncomment below to prevent 'tilde backup files' (eg. myfile.txt~) from being created
"set nobackup
" Uncomment below to cause 'tilde backup files' to be created in a different dir so as not to clutter up the current file's directory (probably a better idea than disabling them altogether)
set backupdir=C:\Windows\Temp
" Uncomment below to disable 'swap files' (eg. .myfile.txt.swp) from being created
set noswapfile
You can set backupdir and directory to null in order to completely disable your swap files, but it is generally recommended to simply put them in a centralized directory. Vim takes care of making sure that there aren't name collissions or anything like that; so, this is a completely safe alternative:
set backupdir=~/.vim/backup/
set directory=~/.vim/backup/
If you are using git, you can add *.swp to .gitignore.
If you put set directory="" in your exrc file, you will turn off the swap file. However, doing so will disable recovery.
More info here.
create no vim swap file just for a particular file
autocmd bufenter c:/aaa/Dropbox/TapNote/Todo.txt :set noswapfile
For anyone trying to set this for Rails projects, add
set directory=tmp,/tmp
into your
~/.vimrc
So the .swp files will be in their natural location - the tmp directory (per project).
How do I specify Vim settings for all files under the current directory?
The ideal solution would be if Vim searched for and read a .vimrc in the current directory before searching for ~/.vimrc, and apply the settings there for the entire tree.
I've seen a plugin, but this means the applied settings aren't transparent since they require the plugin to be installed. In contrast, a modeline is transparent since regardless of a user's vimrc or specific vim invocation the modeline settings will be applied for that file.
Things I tried are
placing a .vimrc in the working directory
:so vimrc in the modeline.
I suppose both don't work for security reasons. I don't need the full power of a vimrc; being bound to settings acceptable by a modeline would suffice. My goal is to make it easier for vimmers to adopt coding standards in a project.
You can put something like this in $VIM/vimrc
autocmd BufNewFile,BufRead /path/to/files/* set nowrap tabstop=4 shiftwidth=4
I'd strongly suggest not using set exrc
Even with set secure, under *nix, vim will still run autocommands, shell, et al, if you own the file. So if you happend to edit a file in that tarball I sent you with a .vimrc containing:
autocmd BufEnter * :silent! !echo rm -rf ~/
you'll probably be less amused than I will.
I'm an advocate of the plugin way.
For several reasons:
Modelines are particularly limited: we can't set variables (that tunes other (ft)plugins, like "should the braces of the for-snippet be on a newline ?"), or call function from them (I don't limit myself to coding standards, I also set the makefile to use depending on the current directory)
DRY: with modelines, a setting needs to be repeated in every file, if there are too many things to set or tunings to change, it will quickly become difficult to maintain, moreover, it will require the use of a template-expander plugin (which you should consider if you have several vimmers in your project).
Not every one uses vim to develop. I don't want to be bothered by other people editor settings, why should I parasite theirs?
It's easier to ask vimmers to install a same plugin, instead of asking them to copy-paste, and maintain, the same lines in their .vimrc
The settings can be saved with the other project files (cvs/svn/git/whatever)
It's really easy to have a configuration file per project -- with the plugin, I have a global configuration file for the coding standards of the overall project, and specific configuration files for each sub-project (which makefile to use, which executable to call, ...)
BTW, sth's solution can be used to source a single configuration file. This is very similar to the plugin approach except the .vimrc has to be parasited with non global options, and it does not support easily multiple/shared configuration files.
This question is old, but it seems like a pretty natural and persistent concern.
My solution is pretty simple. I place a .vimrc file in the root directory of my projects. The first line of the .vimrc file usually sources ~/.vimrc, and then adds the particular configuration I want. I alias tvim='vim -u .vimrc', and use tvim in my personal project directories. "tvim" for "trusted vim," meaning that if I execute it in a directory with a .vimrc file and something goes wrong, I've got no one to blame but myself, since I explicitly said I trusted it. Also, I keep a group of these stored away so that I can sometimes just softlink the one I want for a particular kind of project.
Placing a .vimrc in the working directory actually is supported, only disabled by default. See :h 'exrc' and :h startup for details, setting 'exrc' will enable reading .vimrc from the current directory.
It's also recommended to :set secure when using this. This locks down :autocmd, shell and write commands for .vimrc in the current directory.
Another thing that might be worth looking at is setting up a session (:h session) with a standard view and settings for the project.
All that said, I would probably go with the plugin option detailed by Luc Hermitte myself.
To minimize security risks with ANY "autorun" features for ANYTHING these days, may I advise you to utilize vim's existing features instead of plugins (portability baggage)?
Eg.
My local folder's vimrc file is named "_gvimrc" (on purpose). This reduces the hope for people like phen from amusing himself at our expense. :-)
In my $VIM/.vimrc file, I inserted:
if filereadable("_gvimrc")
source _gvimrc
endif
at the end.
I use "filereadable()" over "fileexists()" as the later has some quirkiness when tortured with opening multiple (10+) files simultaneously, (not sure why).
Of course, you can give your own unique filename to obfuscate potential trouble-makers further. Such as "_mygvimrc", "_gobbledygook", etc. You just need to settle on one standardized name and source it accordingly in your $VIM/.vimrc. Relying on vi/vim internals for this rules out portability issues. BUT, DO NOT name it .vimrc (or _vimrc) to prevent recursive sourcing in case you're editing the $VIM/.vimrc file with vim later.
Been using this since Windoze 98SE, through Windork XP Pro, and now Windorkier 7 (5+ years already). I'll mark a list of .txt files in Explorer and then use "Edit with multiple Vim", resulting in multiple vim windows opening simultaneously. For my work, I do this several times a day, daily. All files got treated with what I set in my local _gvimrc.
Use "editorconfig"
If the kinds of coding standards you would like to enforce are related to indentation style, tab size, file format and charset, then you might want to look into "editorconfig", which is a cross-editor standard to specify this kind of settings in a specific project, and have all editors follow that configuration.
The "editorconfig" specification allows projects to request different settings depending on file extensions or names within the project. (So you can have Makefiles using TABs, your Python scripts using 4 spaces and your shell scripts using 2 spaces for indentation.)
You need a plug-in to use "editorconfig" in Vim. The official website provides one, but personally I'd recommend sgur/vim-editorconfig, which is written in pure Vimscript, so you don't need to worry about external dependencies too much.
Since "editorconfig" aims at cross-editor compatibility, it's quite limited in what it does, so if you want is consistent whitespace, file format (DOS vs. Unix) and encoding (Unicode utf-8, etc.), then "editorconfig" is for you.
Assuming people aren't adding files every few days, you can probably add a modeline at the top of each file. In fact, if your version control system allows it, you could probably enforce a rule that says that each file must have a modeline when it's checked in.
I agree with the plugin approach for security reasons.
There is a very good plugin which has not been mentioned yet. It lets you use a .lvimrc in your project directories.
Try "localvimrc" out:
http://www.vim.org/scripts/script.php?script_id=441
https://github.com/embear/vim-localvimrc
Try vim-localrc
~/
|- .local.vimrc (1)
`- project/

I looked at the plugins that existed and didn't really fancy any of them, so I wrote a simple function that piggy backs on vim-fugitive. The advantage of this is that it knows the root of the project is always the root of the repository, and additionally I can hash the file to keep a trust table. Just put the following in your .vimrc file.
function LoadRepoVimrc()
let l:path = fugitive#repo().tree('.vimrc')
if filereadable(l:path)
let l:sha1 = fugitive#repo().git_chomp('hash-object',l:path)
if !exists('g:SAFE_VIMRC') | let g:SAFE_VIMRC = {} | endif
if has_key(g:SAFE_VIMRC,l:path) && g:SAFE_VIMRC[l:path] ==? l:sha1
execute 'source '.fnameescape(l:path)
elseif confirm("Trust ".l:path."?", "&Yes\n&No",2) == 1
let g:SAFE_VIMRC[l:path] = l:sha1
execute 'source '.fnameescape(l:path)
else
execute 'sandbox source '.fnameescape(l:path)
endif
endif
endfunction
autocmd User FugitiveBoot call LoadRepoVimrc()
set viminfo ^= !
If the ! option is set on the viminfo setting, then the SAFE_VIMRC dictionary will be preserved between runs (note the ^ to prepend the option so it doesn't mess up the n option).
