>>Are there two separate FS objects for that? No there is one global fs that is shared with all environment objects.
After the Sconstruct are read in this will hold all nodes that are known to the SCons and their relationships. The scanner have not been run yet, so there might be some node that are still to be added as dependent children. I think a call to get_children() will call the scanners however and return all explicit and implicit node dependents for a given node.

Nowhere should you need FS. First, I don't need to do this from SConstruct. I am looking how to add new debug option to scons itself. So, there is no graph I can dump? Just a list of targets that are being traversed using sources? If so, then that means that every target should be a filesystem object? What is target then? If it is a name, how a lookup if made to locate it in FS tree? -- anatoly t. _______________________________________________ Scons-dev mailing list [email protected] https://pairlist2.pair.net/mailman/listinfo/scons-dev _______________________________________________ Scons-dev mailing list [email protected] https://pairlist2.pair.net/mailman/listinfo/scons-dev
