Before today I was using /etc/vim/vimrc to configure my vim setup. Today I thought of creating .vimrc file. So, I used
touch .vimrc
cat /etc/vim/vimrc > .vimrc
So, now when I open any file with vim I get the following errors:
Error detected while processing /home/ronnie/.vimrc:
line 68:
E122: Function SplitColors already exists, add ! to replace it
line 77:
E122: Function ChangeColors already exists, add ! to replace it
line 171:
E174: Command already exists: add ! to replace it
line 174:
E174: Command already exists: add ! to replace it
Press ENTER or type command to continue
I have both /etc/vim/vimrc and .vimrc file located in my system. So, is this the reason I am getting this error because from now on I would like to use only .vimrc to configure my vim setup.
You're defining functions that have the same name as some already defined. Adding an exclamation mark after function "overwrites" the previous definition, and in your case will stop the error message from showing.
This is the solution by example since most of the answers are correct above but they don't directly help you solve the problem. Areas of interest in bold.
" code with redefinition issues
function CloseDuplicateTabs() endfunction
command CloseDupTabs :call CloseDuplicateTabs()
" fixed code with overrides
function! CloseDuplicateTabs() endfunction
command! CloseDupTabs :call CloseDuplicateTabs()
Why not add ! to your function definitions as suggested? it will make vim stop complaining.
Alternatively you could remove those definition from /etc/vim/vimrc
The problem is that both /etc/vim/vimrc and .vimrc are sourced. This depends on several factors; see the details at :help .vimrc.
In general, the system-wide Vim config should reside in the former file, and your personal customizations in the latter. For single-user systems, there isn't much of a difference, but you did the right thing in moving the stuff into your home directory. Just delete the duplicate functions etc. from the former file, or remove it completely if you've moved everything to your .vimrc.

If I open a file in a current directory using netrw and then reopen the netrw using :Sexplore the netrw window opens below (I have splitbelow set), but the cursor remains in the file being edited and I cannot move to the netrw window using CTRL-W combinations.
Am I doing something wrong or is this a bug?
Steps to reproduce
run vim .
netrw opens, highlight a file in the current directory (let's say test.txt) and press Return, file test.txt opens
run :Sexplore cmd
netrw opens below but the cursor remains in the file opened previously.
My .vimrc

VIM version
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Dec 8 2015 23:11:08)
MacOS X (unix) version
Included patches: 1-944
This is how it looks like:
I cannot reproduce with version 154a (use :echo g:loaded_netrwPlugin to check your netrw version).
Try with the latest version.
Edit:
It is possible that the problem is cause by some other plugin interference or settings. You could try following the approach described at Vim FAQ 2.5:
2.5. I have a "xyz" (some) problem with Vim. How do I determine it is a
problem with my setup or with Vim? / Have I found a bug in Vim?
First, you need to find out, whether the error is in the actual
runtime files or any plugin that is distributed with Vim or whether it
is a simple side effect of any configuration option from your .vimrc
or .gvimrc. So first, start vim like this:
vim -u NONE -U NONE -N -i NONE
This starts Vim in nocompatible mode (-N), without reading your
viminfo file (-i NONE), without reading any configuration file (-u
NONE for not reading .vimrc file and -U NONE for not reading a .gvimrc
file) or even plugin.
(...)
If the error does not occur when starting Vim this way, then the
problem is either related to some plugin of yours or some setting in
one of your local setup files. You need to find out, what triggers the
error, you try starting Vim this way:
vim -u NONE -U NONE -N
If the error occurs, the problem is your .viminfo file. Simply delete
the viminfo file then. If the error does not occur, try:
vim -u ~/.vimrc --noplugin -N -i NONE
This will simply use your .vimrc as configuration file, but not load
any plugins. If the error occurs this time, the error is possibly
caused by some configuration option inside your .vimrc file. Depending
on the length of your vimrc file, it can be quite hard to trace the
origin within that file.
The best way is to add :finish command in the middle of your .vimrc.
Then restart again using the same command line. If the error still
occurs, the bug must be caused because of a setting in the first half
of your .vimrc. If it doesn't happen, the problematic setting must be
in the second half of your .vimrc. So move the :finish command to the
middle of that half, of which you know that triggers the error and
move your way along, until you find the problematic option. If your
.vimrc is 350 lines long, you need at a maximum 9 tries to find the
offending line (in practise, this can often be further reduced, since
often lines depend on each other).
Obviously you will have to load netrw manually (which can be done by sourcing plugin/netrwPlugin.vim -- if you are using some plugin manager you will have to move the plugin to ~/.vim/ or change your runtime path due to the autoload functions) and set nocompatible and splitbelow.
Actually there is an adapted version of this procedure in :help netrw-debug:
Step 2: assuming that you've installed the latest version of netrw,
check that your problem is really due to netrw. Create a file called
netrw.vimrc with the following contents:
set nocp
so $HOME/.vim/plugin/netrwPlugin.vim
Then run netrw as follows:
vim -u netrw.vimrc --noplugins [some path here]
Perform whatever
netrw commands you need to, and check that the problem is still
present. This procedure sidesteps any issues due to personal .vimrc
settings and other plugins. If the problem does not appear, then you
need to determine what setting in your .vimrc is causing the conflict
with netrw or which plugin.
Step 3: If the problem still is present, then get a debugging trace
from netrw:

I am trying to customize vim highlighting by placing additional instructions into local config $project/.lvimrc, which is managed by the https://github.com/embear/vim-localvimrc plugin.
Unfortunately, it seems that commands like
syntax match Operator "\<MYOP\>"
located in .lvimrc are ignored silently by vim. Typing the command in the command line works as expected. Other commands from .lvimrc also work. So what may stop vim from interpreting local highlighting correctly?
That was because https://github.com/embear/vim-localvimrc plugin launches local files in a sandbox by default. Syntax commands are not allowed in a sandbox (at least in my setup), so the exception was raised. For some reason, Vim handles such exceptions silently.
In my case, the following modifications formed a solution:
Disable sandboxes for localvimrc by adding let g:localvimrc_sandbox = 0 to master .vimrc file
Add set conceallevel=2 to the localvimrc
It could be a problem with the loading order, i.e., your .lvimrc is loaded, then the filetype syntax is loaded and overwrites the .lvimrc syntax commands. You could check that by including echom statements on both files.
Also notice that the local vimrc is not the standard way of customizing syntax highlight. From Vim FAQ 24.11:
You should not modify the syntax files supplied with Vim to add your
extensions. When you install the next version of Vim, you will lose your
changes. Instead you should create a file under the ~/.vim/after/syntax
directory with the same name as the original syntax file and add your
additions to this file.

I want vim to save folded code after I've closed the file. I've added the following code to both /etc/vimrc and ~/.vimrc:
au BufWinLeave ?* mkview
au BufWinEnter ?* silent loadview
When I open a file as a regular user (vim file) it works as expected. If I instead open with sudo vim file it doesn't save folded code.
I know /etc/vimrc is being read. My theme is set at the bottom of that file and is working fine. I ran into a similar problem last week installing the vim surround plugin. When that was installed in ~/.vim it only applied to vim file. To get it working with sudo I had to install it separately in /usr/share/vim/current. What could be causing this?
Prolog
In fact you answered your question, so this is indeed the same issue you had before. It is caused by the algorithm Vim uses to find its configuration (see :help initialization). But I wouldn't call your solution a correct one. See :help $VIM for information how you can use your configuration in sudo environment (e.g. being root).
As for your current issue.
See the following quotes from the documentation. :help :mkview:
:mkvie[w][!] [file] ...
When [file] is omitted or is a number from 1 to 9, a
name is generated and 'viewdir' prepended.
...
And :help 'viewdir':
'viewdir' 'vdir' string (default for ... for Unix: "~/.vim/view", ...
So after doing sudo all views are stored by Vim at /root/.vim.
Solution
Make viewdir point to your ~/.vim/view directory, with something like the following in /root/.vimrc:
:set viewdir=/home/user/.vim/view
Though, this approach has some issues itself:
Updating views saved by root will cause permission errors.
You wont be able to pass stored views for files under /root or /home/user, because Vim generates file names with tilde instead of full paths.
The first issue can be solved by running chown or chmod on new view file right after executing :mkview command. It should be something like:
execute '!chown user:group' eval('&viewdir').'/'.substitute(expand('%:p:~'), '/', '+=', 'g').'='
But I don't know good solution for the second issue, can only suggest writing a script to convert file names to full paths.
I share an user with other people.
Everyone has created a directory into home directory and everyone is working in his "own" directory.
I want to use my own setting when I use vim and I don't want to bother others with my preferences.
I created my .vimrc file into $HOME/my_directory
I've defined an alias my_vim="vim -u /full_path_to_home/my_directory/.vimrc"
When I edit a file with my_vim, I don't have the right colors.
I have the same problem when I use the command
:source /full_path_to_home/my_directory/.vimrc
If I copy my .vimrc file into $HOME directory, everything is fine.
Where is the problem ?
From :help vimrc
If Vim was started with "-u filename",
the file "filename" is used.
All following initializations until 4.
are skipped.
So by specifying a vimrc file, its ignoring the system-wide vimrc (/erc/vimrc/) where syntax highlighting and other things are configured. You can work around this problem by adding the following code to the top of your vimrc:
if filereadable("/etc/vimrc")
source /etc/vimrc
endif
If this sort of thing comes up a lot, I would recommend changing your $HOME to point to the current $HOME/my_directory whenever you log in.
So I work in a PHP shop, and we all use different editors, and we all have to work on Windows. I use vim, and everyone in the shop keeps complaining that whenever I edit a file there is a newline at the bottom. I've searched around and found that this is a documented behavior of vi & vim... but I was wondering if there was some way to disable this feature. (It would be best if I could disable it for specific file extensions).
If anyone knows about this, that would be great!
And for vim 7.4+ you can use (preferably on your .vimrc) (thanks to 罗泽轩 for that last bit of news!):
:set nofixendofline
Now regarding older versions of vim.
Even if the file was already saved with new lines at the end:
vim -b file
and once in vim:
:set noeol
:wq
done.
alternatively you can open files in vim with :e ++bin file
Yet another alternative:
:set binary
:set noeol
:wq
see more details at Why do I need vim in binary mode for 'noeol' to work?
Add the following command to your .vimrc to turn of the end-of-line option:
autocmd FileType php setlocal noeol binary fileformat=dos
However, PHP itself will ignore that last end-of-line - it shouldn't be an issue. I am almost certain that in your case there is something else which is adding the last newline character, or possibly there is a mixup with windows/unix line ending types (\n or \r\n, etc).
Update:
An alternative solution might be to just add this line to your .vimrc:
set fileformats+=dos
There is another way to approach this if you are using Git for source control. Inspired by an answer here, I wrote my own filter for use in a gitattributes file.
To install this filter, save it as noeol_filter somewhere in your $PATH, make it executable, and run the following commands:
git config --global filter.noeol.clean noeol_filter
git config --global filter.noeol.smudge cat
To start using the filter only for yourself, put the following line in your $GIT_DIR/info/attributes:
*.php filter=noeol
This will make sure you do not commit any newline at eof in a .php file, no matter what Vim does.
And now, the script itself:
#!/usr/bin/python
# a filter that strips newline from last line of its stdin
# if the last line is empty, leave it as-is, to make the operation idempotent
# inspired by: https://stackoverflow.com/questions/1654021/how-can-i-delete-a-newline-if-it-is-the-last-character-in-a-file/1663283#1663283
import sys
if __name__ == '__main__':
try:
pline = sys.stdin.next()
except StopIteration:
# no input, nothing to do
sys.exit(0)
# spit out all but the last line
for line in sys.stdin:
sys.stdout.write(pline)
pline = line
# strip newline from last line before spitting it out
if len(pline) > 2 and pline.endswith("\r\n"):
sys.stdout.write(pline[:-2])
elif len(pline) > 1 and pline.endswith("\n"):
sys.stdout.write(pline[:-1])
else:
sys.stdout.write(pline)
I have not tried this option, but the following information is given in the vim help system (i.e. help eol):
'endofline' 'eol' boolean (default on)
local to buffer
{not in Vi}
When writing a file and this option is off and the 'binary' option
is on, no <EOL> will be written for the last line in the file. This
option is automatically set when starting to edit a new file, unless
the file does not have an <EOL> for the last line in the file, in
which case it is reset.
Normally you don't have to set or
reset this option. When 'binary' is
off the value is not used when writing
the file. When 'binary' is on it is
used to remember the presence of a
for the last line in the file,
so that when you write the file the
situation from the original file can
be kept. But you can change it if you
want to.
You may be interested in the answer to a previous question as well: "Why should files end with a newline".
I've added a tip on the Vim wiki for a similar (though different) problem:
http://vim.wikia.com/wiki/Do_not_auto-add_a_newline_at_EOF
OK, you being on Windows complicates things ;)
As the 'binary' option resets the 'fileformat' option (and writing with 'binary' set always writes with unix line endings), let's take out the big hammer and do it externally!
How about defining an autocommand (:help autocommand) for the BufWritePost event? This autocommand is executed after every time you write a whole buffer. In this autocommand call a small external tool (php, perl or whatever script) that strips off the last newline of the just written file.
So this would look something like this and would go into your .vimrc file:
autocmd! "Remove all autocmds (for current group), see below"
autocmd BufWritePost *.php !your-script <afile>
Be sure to read the whole vim documentation about autocommands if this is your first time dealing with autocommands. There are some caveats, e.g. it's recommended to remove all autocmds in your .vimrc in case your .vimrc might get sourced multiple times.
I've implemented Blixtor's suggestions with Perl and Python post-processing, either running inside Vim (if it is compiled with such language support), or via an external Perl script. It's available as the PreserveNoEOL plugin on vim.org.
Starting with vim v7.4 you can use
:set nofixendofline
There is some information about that change here: http://ftp.vim.org/vim/patches/7.4/7.4.785 .
Maybe you could look at why they are complaining. If a php file has a newline after the ending ?>, php will output it as part of the page. This is not a problem unless you try to send headers after the file is included.
However, the ?> at the end of a php file is optional. No ending ?>, no problem with a newline at the end of the file.
Try to add in .vimrc
set binary
I think I've found a better solution than the accepted answer. The alternative solutions weren't working for me and I didn't want to have to work in binary mode all the time.
Fortunately this seems to get the job done and I haven't encountered any nasty side-effects yet: preserve missing end-of-line at end of text files. I just added the whole thing to my ~/.vimrc.
Would it be possible for you to use a special command for saving these files?
If you do :set binary, :w and :set nobinary the file will be written without newline if there was none to start with.
This sequence of commands could be put into a user defined command or a mapping, of course.
I found this vimscript plugin is helpful for this situation.
