My publisher requires that I write in MS Word, but it’s so clunky on a Mac (and iWork so smooth) that I write each chapter in a mixture of text files and iWork documents and convert it to MS Word at the last minute. But there’s one big problem with the way iWork saves files.

I have a subversion repository for all my writing projects. Every time I step away from the computer after having made a change to one I check everything in so next time I have an idea I can pick up where I left off no matter where I am. I started noticing a funny pattern with iWork documents that has since caused me to put svn:ignore status on all of them: iWork keeps overwriting my .svn directory.

The problem is that iWork apps save their files as directories. In Finder, they look like ordinary files, but try opening up the console to see their true nature for yourself:

$ ls -l
total 688
-rw-r--r-- 1 ted ted 349696 Aug 27 06:52 189481_ch04.doc
drwxr-xr-x 8 ted ted 272 Aug 27 06:36 189481_ch04.pages

When you do an svn add on the pages files, it does what SVN normally does when it encounters a directory: it traverses recursively through it, adding .svn directories along the way, and adds every file within it.

For the initial checkin, everything works fine, but once you open up iWork and edit your file the problems start.

$ svn update
svn: Working copy '.' locked
svn: run 'svn cleanup' to remove locks
(type 'svn help cleanup' for details)


$ svn status
L .
M 189481_ch04.doc 
~ 189481_ch04.pages

Apparently iWork doesn’t like other programs adding content to their files.. er.. directories.. er.. file-directories. The .svn folder is overwritten, completely messing the whole version controll tree (if you’re the kind of person that likes to commit and update in batch). It seems that Apple is moving toward the “managed directory” style of information management. Instead of one large file to store a particular document or presentation, you get a whole directly that masquerades as a file (I think NeXT did this a lot..).

That is a cool choice, I suppose – as a developer I would certainly rather manage a directory of files than one ginormous monolithic on. But at some point Apple is going to have to address the fact that many command line utilities will either get confused at this style of file storage or, like SVN and CVS, will try to add their own data into the mix. Pages is a wonderful word processor, and as of iWork 08 I don’t really see a need to ever fire up Office X unless I have to (Office for Windows is great…the OS X version is just a piece..). But this is a huge problem for anyone who uses version control regularly, and I hope either a fix or a work around is devised soon.
