Made myself a li’l Ruby class for sending email.
But of course I’d like to wrap the outgoing body of text at
68 characters or so, before sending.
Having taken PHP’s “wordwrap” function for granted,
(http://us2.php.net/wordwrap), I was surprised not to find
a similar method built-in to Ruby.
Or is it?
Did I miss it?
Am I going to have to write my own?
Try searching for “gsub \1 \n” in the comp.lang.ruby search bar at
http://www.rubyforge.org. The first result is a discussion about a wrap
method.

Here’s a simple one I like to use:
class String
def wordwrap( len )
gsub( /\n/, “\n\n” ).gsub( /(.{1,#{len}})(\s+|$)/, “\1\n” )
end
end
s = “Insert unwrapped and elaborate, exhaustive tomes here.”
s.wordwrap( 68 )
#=> outputs string wrapped to 68 columns
However, the String#wordwrap method is rather limited, so if I ever end
up needing something more, I use the Text::Format[1] module.
require ‘text/format’
formatter = Text::Format.new {
@columns = 68
@first_indent = 0
}
s = “Insert unwrapped and elaborate, exhaustive tomes here.”
formatter.format( s )
Yip.
_why
There’s a wrap implementation in ‘rough’ (a CVS repository of
candiates for the Ruby standard library), as well as a few other text
manipulation things. I’d like to see them all become standard,
although better organised than they are now.
