I’m spending an hour or two today going through Ruby’s standard
library, seeing what’s in there.
What the hell is WeakRef used for? How is that useful?

Also, there’s hardly any documentation for Tracer. Had to look it up
in Pickaxe2.
How does one go about creating and submitting documentation for these
things? It’s probably not acceptable to use a direct, attributed
quote from the Pickaxe book for those things, right?

Consider a cache whose entries are ok to be garbage collected.

That’s one of my favorite pass times. Are we uber geeks or what?

How about caching? Build up a big cache for some process intensive
values, but allow GC to clean house when it needs to because you
could always refigure them.

Ah, ok. That info could go in the RDoc.

What about this?

Yeah, I think no documentation for any of the methods would certainly
qualify as “hardly any documentation” …

A few seconds in IRb got me this:
[olympic]$ irb
irb(main):001:0> require “tracer”
=> true
irb(main):002:0> Tracer.on { “Foo”.to_a.reverse }
#0:(irb):2:Object:-: -
#0:(irb):2:Enumerable:>: -
#0:(irb):2:String:>: -
#0:(irb):2:String:<: -
#0:(irb):2:Enumerable:<: -
#0:(irb):2:Array:>: -
#0:(irb):2:Array:<: -
=> [“Foo”]
irb(main):003:0> Tracer.on { (1…20).to_a.reverse }
#0:(irb):3:Object:-: -
#0:(irb):3:Object:-: -
#0:(irb):3:Enumerable:>: -
#0:(irb):3:Range:>: -
#0:(irb):3:Range:<: -
#0:(irb):3:Enumerable:<: -
#0:(irb):3:Array:>: -
#0:(irb):3:Array:<: -
=> [20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2,
1]
irb(main):004:0> Tracer.on { @a = 3 }
#0:(irb):4:Object:-: -
=> 3
irb(main):005:0> Tracer.on { @a }
#0:(irb):5:Object:-: -
=> 3
This looks interesting. If I document this class where should I send
my documentation?

Hang out on ruby-doc or ruby-core mailing list; I believe you can post
to ruby-code and get someone with commit rights to add it in if it looks
right.

quote from the Pickaxe book for those things, right?
Why not? Seems like fair use.

Get a CVS checkout of HEAD and add the documentation to the
appropriate files.
Be sure to add or edit the appropriate .document files.

You’ll have to check with Dave T… Much of the current RDoc
comes from the first pickaxe.

I saw this, read this, some how skipped to the wrong page, and said,
this doesn’t have enough information. Now that I’m looking at the
right stuff, I am better situated.
