Re: [platform-debug-dev] Support for specifying Environment from Launch

[Darin_Wright@xxxxxxx]

Providing environment support in a generic, re-useable location would be beneficial. The obvious location for environments is in the debug core (however, this would not be a 2.0 feature, as time has run out for new features). Environments are not applicable to every type of launch configuration, so I envision the following support:

(1) A way to define/persist environments by name (in org.eclipse.debug.core)
(2) A way to manipulate environments by the user (in org.eclipse.debug.ui)
(3) A re-useable launch configuration tab for choosing/editing environments (in org.eclipse.debug.ui)

With this breakdown, launch configurations that support environments could simply re-use the appropriate tab.

Question: Your document correctly points out that the evironment cannot be directly modified by a Java program, but it also states that as part of the CDT startup process, the "read-only" environment is queried. How do you perform this query? Looking at the JavaDoc for java.lang.System.getEnv(...), there is also no way to retrieve the envrionment from a Java program.

Hi All,

I've created an initial design proposal for uniformly handling Environment
Variables across various functions in the CDT (C/C++ Development Tools),
such as building, running arbitrary commands, and debugging and am
wondering if this would have value for other teams.  .A user can create
named Environments that contain Environment Variables and override other
Environments (such as the default System Environment that was present when
the user started Eclipse).  Then in the various places the user simply
chooses which named Environment should be applied to the given action.
Here is the link to the document:
http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/cdt-core-home/designs/environment_proposal.html?cvsroot=Tools_Project

The questions are:
1.  Are other teams currently implementing something similar?
2.  Does it make sense to add some sort of support for this feature to
Launch Configurations?

I'm not very familiar with the Launch Configuration stuff, so I'm not
really sure the best way this sort of thing would be supported, if at all.
I defer to the experts ;-)

Thanks...
