Re: Re: Need some help: was: svn commit: r1885148 - /turbine/core/branches/URLMapperService/ - about yaml

[Georg Kallidis <ge...@cedis.fu-berlin.de>]

yes, the problem is that although commons configuration does implement 
yaml style, it's intention is "configuration", which is very similar like 
reading single entries (line by line) in property style - not 
mapping/deserializing it into a class. 

This was done here for the url mapper quite easily, as the mapping classes 
already existed. Another advange was, that in the map patterns the xml 
entity escaping could be removed, which makes them more readable... 

But it was kind of an exercise/showcase. 

Using it (e.g. in a fulcrum component) would imply a different mechanism 
than now: Dropping the commons configuration and instead mapping the yml 
file to a mapper class, where the configuration assignments would take 
place or could be retrieved. This is just a thought about, how this might 
be used at more places. May be the intake fulcrum component would be the 
best candidate, as there already xml mapper classes are provided ...

Generally I think using yaml does lower the entry bar level to use a 
software project (i.e. Turbine) and might even what "newcomers" expect. If 
it could be done (as in this case) with very little effort, I think we 
could afford to provide it (at least as an optional feature, which it's 
still).

Hi Georg,

I like the YAML configuration approach. It looks much cleaner than the 
chatty XML file.

We don't have this configuration format anywhere else, however. That 
makes three different config formats within Turbine: properties, xml and 
yaml. Looks clumsy to me.

Bye, Thomas
