Oliver Heger commented on CONFIGURATION-284:
--------------------------------------------
Joerg, I think this is a misunderstanding: This feature request is about
environment variables, while Configuration so far only supports Java's system
properties.
I had a vague memory that the topic "access to environment variables" was
discussed before on the commons mailing list, and found this reference:
http://thread.gmane.org/gmane.comp.jakarta.commons.devel/33239/focus=33325
Obviously this thread did not come to a final solution, AFAIK this feature was
not added to one of the commons libraries. If it was (for instance in
commons-lang), it would be really easy to incorporate it into
commons-configuration. But having to implement it ourselves, situation looks
different. The problem I see here is that it will really be difficult to
implement a robust and portable solution, and besides this feature is probably
out of scope for commons-configuration.
>From Java 1.5 on, access to environment properties will be possible using
>methods of the System class. So when we switch to this version (no idea when
>this will happen though) it will be no problem to satisfy this request. But
>for the moment I am reluctant.
> ability to read OS environment variables

> Key: CONFIGURATION-284
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-284
> Project: Commons Configuration
> Issue Type: New Feature
> Components: Interpolation
> Reporter: Aksel Schmidt
> Priority: Minor
>
> suggestion:
> interpolation with system environment, i.e.
> ${sys:user.name} reads from systemproperties (as of today)
> ${sysenv:TEMP} reads from OS environment
> these can be parsed from a supported set of OS's - windows read from a set in
> a "cmd /c", unix/linux from an "env" etc. (just once on demand)
