Never under estimate what you can achieve with
IO.read( "filename").scan(%r{}mx) do |match|
end
Especial as you can control how greedy the regex is with .*?
I just deleted a lot of code and replaced it with one line.

Carter's Clarification of Murphy's Law.
"Things only ever go right so that they may go more spectacularly wrong later."
From this principle, all of life and physics may be deduced.
# Read and parse the first file on the command line.
gets(nil).scan( //mx ) { |s|
}
# Read and parse the rest of the files.
ARGF.read.scan( //mx ) { |s|
}
blah
Command :
some stuff
some more stuff I \
want with line continuation \
characters
blah
Command :
more some stuff
more some more stuff I \
want with line continuation \
characters
blah
...
that I wanted transformed into
some stuff
some more stuff I want with line continuation characters
more some stuff
more some more stuff I want with line continuation characters
So I started write a routine to fix up the \ characters yield fixed lines and then a state machine to search for 'Command:' and gather everything until the blank line and then skip until...
I start playing with Generator since I realised I could then keep everything in a
each_something do |thing|
yield other_thing( thing)
end
pattern instead of doing state machines and then I threw everything away and replaced it with..
File.read( "big_file").scan(%r{\nCommand\ :\n(.*?)\n\n}mx) do |command|
puts $1.gsub( %r{\\\n}mx, '')
end
and then
everyone.send( :memo, "to self")

Well, as your self.memo included the rest of us, how about
sharing the example?
