find-file-at-point expanding environment variables?

[David Rogoff]

I could use some help.  I use ffap (bound to c-x c-f) all the time. 
However, I edit many files in which there are references to filenames 
that use shell environment variables as part of the path.  For example 
-  /home/${USER}/.cshrc .  Is there a way for ffap to expand/substitute 
this?  It would make my life a lot easier.

Thanks,

 David

I did some experimenting and see that ffap will expand variables ... 
except if they are enclosed in curly braces. This isn't too bad a 
limitation, but it would be better if I didn't have to edit the files 
and remove the curly braces.

(add-to-list 'ffap-string-at-point-mode-alist
             '(file "--:\\\\$+<>@-Z_[:alpha:]~*?{}" "<@" "@>;.,!:"))
             
Try this.
-ap

Great -it appears to work perfectly!

Thanks,
