Vim Color Schemes

Since deciding to get into Vim, I seem to have wasted a considerable about of time on color schemes! After discovering how to get 256 colors in my terminal window (Hint: It works with PuTTY out of the box, just set your TERM environment variable to xterm-256color),  I decided to put together my own 256 color themes.  Well, sort of.  I actually just copied the code from the Wombat theme by Lars H. Nielsen and modified the colors.

This is the one I'm using by default, it's high-contrast and it seems to work very well for the Perl/Template/JS/HTML editing I am doing most of the time. On account of the many bright colors (which I'm sure other people will think look ridiculous), I call this scheme Harlequin.




Inspired by the green/brown/white colors deployed by the marketing droids of the on-site coffee vendors where I work, I have created this scheme named Starbucks.




And of course to round things out and bring some balance, here is this truly evil dark-side scheme which I call Magma.




Of course, there are those who say that Starbucks® is the true evil, but I digress...

SVN deletion goodness

The process of getting a project which was not under version control into SVN can be a chore.  Usually the lack of source control has forced the creation of loads of temporary and backup files with silly names.  The easiest thing to do is to simply import the whole mess into the repository, and then go back and clean it up later.

That's what I was doing earlier this morning.  I checked out a copy and started trimming, and by the time I was ready to commit, I realized I had been accidentally deleting files directly in the shell instead of using svn delete.  Oops!  Now I have to go back re-delete them.  But they're gone, and there were probably a hundred files and directories removed.  Won't that be a huge pain?

Not really.  A little shell one-liner will take care of it for you:

svn status | grep '^!' | awk '{print $2}' | xargs svn del

Run that from the root of your working copy, and it will do the following:

  • Give you the status of all the files and directories in your working copy compared with the repository.
  • Extract only those lines which start with !, which is svn status's way of saying "Oh noes, I can't find that one!"
  • Feed those lines into awk so that it can get the second item on the line, the path.
  • Use xargs to run svn del on each of those paths.

Now all of your deletes will be properly reflected in the repo at the next commit.  Phew!
