Restoring Syntax Highlighting to Vim

Hi!

After doing a couple of updates on my servers today, I noticed that one of them had syntax highlighting in vim disabled. I double-checked to see that it was still vim that was installed, and not vi. Indeed it was, so I tried entering a couple of vim commands in order to re-enable syntax highlighting.

A couple of minutes of trying and searching the Internet went by till I got the idea to directly compare the vim version info both on one of my servers that had it working properly and the one that didn't. It turned out that even though it was the same version number and build with the same compile time it had a certain difference: one line said "Tiny version without GUI." vs. "Huge version without GUI.". The tiny version was the one that wasn't highlighting correctly.

So I checked out what the package manager thought of this:

# yum list *vim*
[...]
Installed Packages
vim-common.i386                                   2:7.0.109-7.el5                                  installed
vim-enhanced.i386                                 2:7.0.109-7.el5                                  installed
vim-minimal.i386                                  2:7.0.109-7.el5                                  installed
Available Packages
vim-X11.i386                                      2:7.0.109-7.el5                                  base

Somehow during updating it had apparently decided to install the vim-minimal package as well. And of course it wasn't installed on the server on which vim worked as it should.

Fair enough. I thought to myself that removing should fix it, but when I tried to it said the following:

# yum remove vim-minimal
Loaded plugins: fastestmirror

Is this ok [y/N]:

That was weird. It felt the need to remove sudo along with it. Of course that was not okay for me, so I tried looking for a parameter for vim in order to ignore the dependencies, but apparently there are none (any more).

The solution I found after a couple of more minutes of searching the Internet was to remove the package via the actual rpm program. But don't you need the original rpm file for vim-minimal? No, you don't!

First you have to find out the complete package name, however. That can be done like this:

# rpm -qa | grep vim-minimal
vim-minimal-7.0.109-7.el5.i386

And finally just use the following command:

# rpm -e --nodeps vim-minimal-7.0.109-7.el5.i386

whereas the last parameter is of course the proper name of the package in question. --nodeps, as you might have figured already, stands for "no dependencies" and removes the package without any questions asked.

In the end, these simple steps restored the syntax highlighting functionality for my vim.

Let's hope that after the next update it doesn't decide to go monochrome again.

Thanks for reading!
