reformating/pretty printing ruby

Graham Foster

I'd like to be able to reformat a block of Ruby within my editor. One
way would be write the block to a text file and use Ruby to figure
out how to prettyprint itself back to stdout, which I can then
capture back into the editor - all spruced up.
Question is - what is does the Ruby look like to pretty print itself?
Regards,
Graham (Newbie)

You don't say which editor, but you can use:

ggVG=

from within vim (in command mode) to reindent a block of code.

I'm a Windows man.. and I don't use VIM. Its PSPAD (http:/....
com) and like many other editors it has a shell to OS and capture
Stdout facility. (I was interested in how to do this reformatting
generically. It looks like there is a Prettyprint module within Ruby
1.8 (its not mentioned in Pickaxe v1), but I don't understand how it
works.

It doesn't pretty print Ruby code. It pretty prints data. It's
something of #inspect on steroids.
