I have a here documents of something like this:
form = <<"DONE"
while( bla ..bla .. bla) do
this
DONE
How can I do a while loop inside a here documents in ruby? Is it
possible?
If you want to use erb, then you can do something like that.
require 'erb'
erb=ERB.new <<-'DONE'
<% 5.times do %>
this text is repeated
<% end %>
DONE
form=erb.result(binding)
Be warned that you have to place the commands correctly to avoid getting
extra newlines. (This is mostly intended for HTML templating, where
newlines don't matter.)

What exactly are you trying to achieve? Do you want to have repeated content from the here doc?

I am not using erb unfortunately, anyway to go around this?

Something like this? Though this has other problems...
STDOUT.sync = true
my_text = <<-FINISHED
Note the sequence of when these things are written.
#{3.times do
puts "Hello"
end
} times a greeting was written.
end of my text
FINISHED
puts my_text

No. You'll have to put the loop outside the string.
