engine.SCons.Variables.ListVariable

This file defines the option type for SCons implementing 'lists'.

A 'list' option may either be 'all', 'none' or a list of names
separated by comma. After the option has been processed, the option
value holds either the named list elements, all list elemens or no
list elements at all.

Usage example:

  list_of_libs = Split('x11 gl qt ical')

  opts = Variables()
  opts.Add(ListVariable('shared',
                      'libraries to build as shared libraries',
                      'all',
                      elems = list_of_libs))
  ...
  for lib in list_of_libs:
     if lib in env['shared']:
         env.SharedObject(...)
     else:
         env.Object(...)
