I’ve just started using these methods in Ruby 1.9 and believe I got  
the API wrong previously. Instead of  
remap\_file(old\_name, new\_name) I have remap\_file(new\_name, old\_name).  
And what I had previously called “unmap”, I think now would be better  
called simply “map”.

Is anyone using these LineCache methods in Ruby 1.8? Note: there is no  
official release of LineCache for 1.9 yet.
