I think a lot of us are using it for bespoke applications and Websites; stuff that clients are waiting for, want “comprehensible” configuration (as one client of mine put it, dissing his current XML-centric app) that doesn’t add significantly to the cost/schedule for development but does give flexibility and ease of maintenance/modification. I’ve run across several projects that make use of Spyc for PHP, which I enthused over in a blog post a few weeks back at http://archlever.blogspot.com/2009/11/reuse-renew-recycle-data-structures.html.

I’d say an overall grand total of around 20 apps and sites I’ve seen using it, of which most have been in the last 12-18 months.

Hope this helps.

I've recently fallen head-over-heels in love with YAML.  Specifically, I'm thinking of configuration files -- I hate the non-standardization and slightly-different-syntax configuration files that exist for thousands of programs.  I've gobbled it up for my own teensy projects.

But AFAIK, the usage/take-up of it seems way out of kilter with how much it promises and how much talk there is of it around.  I've tried to find a list of //significant// applications that use YAML for config.  The only ones I can find are:

* RoR (barely worth mentioning)
* Symfony
* Python App Engine

So, my questions: are there others?  If not, why not?  Is there a single example of an existing application that has made an effort to switch its config syntax to YAML?  Within the context of configuration files, is there a significant competitor to YAML with the promise of standardization?
