+#  This file is a backend to "omniidl", used to generate "Wireshark"

+# Description:
+#
+#   Omniidl Back-end which parses an IDL list of "Operation" nodes
+#   passed from ethereal_be2.py and generates "C" code for compiling
+#   as a plugin for the  Wireshark IP Protocol Analyser.
+#
+#
+# Strategy (sneaky but ...)
+#
+# problem: I dont know what variables to declare until AFTER the helper functions
+# have been built, so ...
+#
+# There are 2 passes through genHelpers, the first one is there just to
+# make sure the fn_hash data struct is populated properly.
+# The second pass is the real thing, generating code and declaring
+# variables (from the 1st pass) properly.

+# TODO -- FS
+#
+# 1. generate hf[] data for searchable fields (but what is searchable?)
+# 2. add item instead of add_text()
+# 3. sequence handling [done]
+# 4. User Exceptions [done]
+# 5. Fix arrays, and structs containing arrays [done]
+# 6. Handle pragmas.
+# 7. Exception can be common to many operations, so handle them outside the
+#    operation helper functions [done]
+# 8. Automatic variable declaration [done, improve, still get some collisions.add variable delegator function ]
+#    For example, mutlidimensional arrays.
+# 9. wchar and wstring handling [giop API needs improving]
+# 10. Support Fixed [done]
+# 11. Support attributes (get/set) [started, needs language mapping option, perhaps wireshark GUI option
+#     to set the attribute function prefix or suffix ? ] For now the prefix is "_get" and "_set"
+#     eg: attribute string apple  =>   _get_apple and _set_apple
+#
+# 12. Implement IDL "union" code [done]
+# 13. Implement support for plugins [done]
+# 14. Dont generate code for empty operations (cf: exceptions without members)
+# 15. Generate code to display Enums numerically and symbolically [done]
+# 16. Place structs/unions in subtrees
+# 17. Recursive struct and union handling [done ]
+# 18. Improve variable naming for display (eg: structs, unions etc)
+#
+# Also test, Test, TEST
+#
+
+
+
+#
+#   Strategy:
+#    For every operation and attribute do
+#       For return val and all parameters do
+#       find basic IDL type for each parameter
+#       output get_CDR_xxx
+#       output exception handling code
+#       output attribute handling code
