We have **FILE** and **LINE** … So it would be nice to have **PRETTY\_FUNCTION**? Is there one or do I have to roll my own out of “caller(1)[0]”? John C.

Ah! Sorry! I was looking under the wrong name… Now, thank you, I’m looking in the right place so I see… ruby --version ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux] $ ruby -e ‘def foo;p **method** ;end;foo’ :foo Are you’re saying that this behaviour change in 1.9?

Doesn’t look like so: sandal:Desktop $ ruby -v ruby 1.9.1 (2008-10-28 revision 19983) [i386-darwin9.4.0] sandal:Desktop $ irb > > **method** > > =\> :irb\_binding > > def foo > > **method** > > end > > =\> nil > > foo > > =\> :foo Just keep in mind that Ruby 1.8.7 isn’t a compatible Ruby 1.8 version. It’s meant for um… I don’t really know what, and if you want your code to run on Ruby 1.8.6 (which is pretty important if you plan to support 1.8 at all, IMO), it’s not there: sandal:prawn $ ruby -v ruby 1.8.6 (2008-08-11 patchlevel 287) [i686-darwin9.4.0] sandal:prawn $ irb > > **method** > > NameError: undefined local variable or method ` **method** ’ for > > main:Object > > from (irb):1 > > from :0
