How can one capture the Ruby source file that gets generated from an Erb  
template?

Thanks,  
Wes

ERB#src

if you’ve got an erb file, you can use the command line erb (erb -x …  
)

Many thanks. That is quite handy.

I did use it to discover that the \<% -%\> syntax doesn’t seem to matter  
anymore. Putting the hyphen before the end tag didn’t appear to  
suppress the “\n” at the end of the line on which it was used.

Again, thanks,  
Wes
