cloned the repo, installed python (http://www.python.org/ftp/python/2.7.2/python-2.7.2.msi), ran the application and I get this error while browser is stuck on http://localhost:9090/p/start, (error 503, server restarting)

Hello there,

I haven't run (or tried to run) Yaki under Windows other than a few initial runs under Cygwin. That doesn't seem to be the real problem here, though - it looks more like some sort of change regarding comparison functions in Python 2.7, but I have Yaki running under Python 2.7 and Pypy on Linux and Mac without that issue ever cropping up.

So I can't really reproduce it, but you can try forcing the return from that lambda to be a an int (it's a straightforward string indexing comparison, so it can't be off for more than a few units).

I converted to an int in Indexer ... now I get another error :

Any chance that Windows is a supported platform ?

Ah, that's now probably due to line break handling, which is different on each OS.

Sadly, I have no real way to debug or maintain a Windows version. I heard from someone porting this to IronPython and .NET a while back, but the only way I ever really tested Yaki on Windows during the early years was under Cygwin (which gives you a UNIX-like runtime environment and corresponding Python).
