I’ve dug through the YAML::Syck library source and the Ruby library,  
but was unable to find what I’m looking for… If the syck parser  
finds a syntax error, it reports the line number of the error. Is  
there a way to obtain line numbers of elements after a successful  
load? This will be necessary in reporting errors in the semantics of  
a configuration file…

For example:  
pets = “—\nPets:\n boss: { species: feline }\n abby: { specied:  
canine }\n…\n”  
y = YAML::load(pets)  
y[‘Pets’][‘abby’].line\_number

> > 3

Has anyone looked at doing this? Is the capability available from the  
libsyck library? I’m interested in getting this info through both the  
Ruby and Perl libraries…
