Hello,
I need to pretty print some Ruby code into HTML.
Any pointers 🙂 ?

vim can do it quite nicely. Not sure how, but I know it can.

If you’re looking for a code highlighter, try Syntax[1] or Coderay[2].

this ruby script uses vim to syntax highlight **any** source code
(fortran, ocaml, idl, etc) to html:
#!/usr/bin/env ruby
require ‘tempfile’
$VERBOSE=nil
STDERR.reopen(Tempfile::new($$)) unless STDIN.tty?
fin = ARGV.shift
fout = ARGV.shift
fin = ((fin.nil? or fin == ‘-’) ? STDIN : open(fin))
fout = ((fout.nil? or fout == ‘-’) ? STDOUT : open(fout,‘w+’))
ts = Tempfile::new($$), Tempfile::new($$)
ts[0].write fin.read
ts.each{|t| t.close}
command = %Q( vim -f +‘syn on’ +‘set filetype=ruby’ +‘set
background=light’ +‘run! syntax/2html.vim’ +‘w! #{ ts[1].path }’ +‘qa!’
- \< #{ ts[0].path } \> /dev/null 2\>&1 )
system command
ts.each{|t| t.open; t.rewind}
fout.write(ts[1].read)
ts.each{|t| t.close!}

I usually use Jedit and the code2html plugin.

Hi All,
I want to embed Ruby in my C++ program. My question relates to thread
safety in Ruby. I have an application that is massively threaded. If I
create an instance of the ruby interpreter per thread, will Ruby operate
in
a thread safe manner?
Thanks.
