[Rails-devel] Rails configuration profiles (was: Planned Release 1.7.0)

[Stefan F. <ste...@we...>]

Frederick:

there is already a 2-tier structure in place: The user settings
are only stored as delta to the selected pre-defined profile.
As there is only one pre-defined profile (the "default" profile) it
is not that obvious now.

The 3rd tier would only make our life easier as it allows to
define the other (predefined) profiles as delta one pre-defined profile.
So adding new options would only require the change of one file instead
of a number equal to the number of pre-defined profiles.

It was obvious now that you had not figure out the existing of a default 
profile as you did not add your new options to that file.
It is the file "default.profile" inside folder data.profiles.
The filetype is a java property file which allows easy loading.
If you prefer we can store it as a xml-file as java allows that too (see 
loadFromXML and storeToXML methods of the java.util.Properties class). 
Currently you rely on the setting for missing values for each option, 
which is not a defined behavior and might change after refactoring.

I did not want to add the defaults to Properties.xml inside the data 
folder following the principle from separating structure definition and 
data. In addition it is much easier to load the data from a property 
file (especially Properties supports a hierarchy approach).

Again I took the opportunity to copy the content of a previous e-mail 
message into the wiki:
