Can you give a specific reference to the place in the YAML spec that says this is allowed? I can only find statements about aliases to nodes (i.e. what you call pure aliases). I can't see any provision for substituting values and then adding to them. So the modules are simply implementing the YAML spec, on my reading. > But it seems that only *pure* aliases (*var) work only in YAML::Syck && > YAML::XS > log_dir: &log *var > > YAML dies with "YAML Error: Can't define both an anchor and an alias". > > And it is not clear for me how to modify *var to say: (this is a syntax > error in all parsers) > log_dir: &log *var/log > > How to use other variables' values in yaml config? I always end up implementing $substition (a la shell or perl) in my app. But then I hate YAML, anyway.
