Joshi,

Thank you for the bug report. To be perfectly honest, I wouldn’t be able to figure out what to do with that error message, since HSX causes wildly strange error messages to be thrown.

But things are getting better! I’ve actually completely removed the HSX (XML) support from Turbinado and replaced it with a custom preprocessor that handles HAML and XHTML. I’m typing up the release notes for Turbinado 0.7 right now, so check back soon. V0.7 is currently on Github @ http://github.com/turbinado.

While loading XMLGenerator.hs in ghci it throws following error:

XMLGenerator.hs:162:16: parse error on input `|'

The code at that place is as follows: fromAttrValue v@(Value needsEscape str) = case str of [ v1+, (| ',', vs@:(_+) |)+ ] -> map (fromAttrValue . Value needsEscape) (v1:vs)

Am I missing some ghc extension? I will appreciate if you explain how this list is created or point to appropriate resources. I know comma-separated lists and the standard list comprehension with pipe operator. But, I don't recognize this v1+ thing.

I would like to contribute and can work on fixing bugs or on code improvements. But, I need some guidance or support from you.

Thanks

This is probably due to using HTTP 4000. Turbinado is currently compatible with HTTP 3000, though I am about to update it to HTTP 4000. Should be done this weekend.

After building turbinado, the URL http://the-machines-name:9999/images/1x1.gif works. But, trying any other controller fails with the following error:

Turbinado/Environment/Types.hs:31:51: HTTP.Request' is not applied to enough type arguments Expected kind', but HTTP.Request' has kind -> *' In the type Maybe HTTP.Request' In the data type declaration forEnvironment'

Am I missing anything? Request really has kind -> and Maybe does expect kind *. I tried replacing Maybe HTTP.Request by HTTP.Request String and that seems to take me beyond that error before failing at other points.

I will appreciate explanation.

Joshi,

Thanks for the note. Since GHC 6.10 is just getting added to Debian (and Ubuntu), there are still some hiccups in the packages. I'll ping the GHC maintainer and suggest that they make libedit-dev a dependency of GHC 6.10. We'd discussed it before.

After upgrading to ghc 6.10 and installing all cabal packages that turbinado depends on, I still got linker error during turbinado build. And I could resolve it only after installing libedit-dev package on Ubuntu. Alson, you might want to include that in your list of dependencies in documentation. configure does not complain about that.

Thanks, Alson. Yes, that was the problem. I was on ghc 6.8 and after upgrading to 6.10 I could compile turbinado fine. Is there a tutorial / hello world?

Vagif,

Documentation is the Achilles heel of open source projects. I've been focused on adding features, but know that documentation is a major problem for Turbinado and will be focusing on that for the next release.

I'm currently oscilating between happstack and turbinado. The first one coming with good tutorial/documentation will probably win me over.

Joshi,

Not sure what is the issue there. Turbinado only compiles with GHC 6.10 and GHC 6.10 includes both base-3 and base-4. My first guess would be that you're using GHC 6.8. Are you using GHC 6.8 or GHC 6.10?
