RAA - darb/0.2

Combines a main script and a list of library files it requires into a single script file. The library files are embedded in the DATA section of this script and loaded on demand using a custom implementation of require that reads from DATA.

Synopsis

  $ cat main.rb
  require 'foo'
  require 'bar'
  p $LOADED_FEATURES[-2,2]

  $ touch foo.rb bar.rb
  $ darb main.rb foo.rb bar.rb >arc.rb
  $ rm foo.rb bar.rb
  $ ruby arc.rb
  ["foo.rb", "bar.rb"]

Changes since 0.1:

• better help text
• shows help if command line is empty or has -h or —help
• generates a hashbang line if darb itself has one
• format of feature name in $LOADED_FEATURES is now consistent with Kernel#require
• now works correctly when some or all input files have cr-lf instead of just lf
• archives generated on windows run on unix/linux and vice versa

Still broken:

• autoload doesn’t look inside the archive, so autoload of external libraries is ok, but not autoload of archived files. Since ruby’s autoload code does not call #require, getting this to work will involve reimplementing autoload using #const_missing.
