# Description:
#
#   Omniidl Back-end which parses an IDL list of "Operation" nodes
#   passed from wireshark_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.
#

"""Wireshark IDL compiler back-end."""

# self - me
# st   - output stream
# node - a reference to an Operations object.

#

#
# TODO -- FS
#
# 1. generate hf[] data for searchable fields (but what is searchable?) [done, could be improved] 
# 2. add item instead of add_text() [done]
# 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) [done]
#
# 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
