  11 #  This file is a backend to "omniidl", used to generate "Wireshark"
  12 #  dissectors from CORBA IDL descriptions. The output language generated
  13 #  is "C". It will generate code to use the GIOP/IIOP get_CDR_XXX API.
  14 #
  15 #  Please see packet-giop.h in Wireshark distro for API description.

  36 # Description:
  37 #
  38 #   Omniidl Back-end which parses an IDL list of "Operation" nodes
  39 #   passed from wireshark_be2.py and generates "C" code for compiling
  40 #   as a plugin for the  Wireshark IP Protocol Analyser.
  41 #
  42 #
  43 # Strategy (sneaky but ...)
  44 #
  45 # problem: I dont know what variables to declare until AFTER the helper functions
  46 # have been built, so ...
  47 #
  48 # There are 2 passes through genHelpers, the first one is there just to
  49 # make sure the fn_hash data struct is populated properly.
  50 # The second pass is the real thing, generating code and declaring
  51 # variables (from the 1st pass) properly.
  52 #

  76 # TODO -- FS
  77 #
  78 # 1. generate hf[] data for searchable fields (but what is searchable?) [done, could be improved]
  79 # 2. add item instead of add_text() [done]
  80 # 3. sequence handling [done]
  81 # 4. User Exceptions [done]
  82 # 5. Fix arrays, and structs containing arrays [done]
  83 # 6. Handle pragmas.
  84 # 7. Exception can be common to many operations, so handle them outside the
  85 #    operation helper functions [done]
  86 # 8. Automatic variable declaration [done, improve, still get some collisions.add variable delegator function ]
  87 #    For example, mutlidimensional arrays.
  88 # 9. wchar and wstring handling [giop API needs improving]
  89 # 10. Support Fixed [done]
  90 # 11. Support attributes (get/set) [started, needs language mapping option, perhaps wireshark GUI option
  91 #     to set the attribute function prefix or suffix ? ] For now the prefix is "_get" and "_set"
  92 #     eg: attribute string apple  =>   _get_apple and _set_apple
  93 #
  94 # 12. Implement IDL "union" code [done]
  95 # 13. Implement support for plugins [done]
  96 # 14. Dont generate code for empty operations (cf: exceptions without members)
  97 # 15. Generate code to display Enums numerically and symbolically [done]
  98 # 16. Place structs/unions in subtrees
  99 # 17. Recursive struct and union handling [done]
 100 # 18. Improve variable naming for display (eg: structs, unions etc) [done]
 101 #
 102 # Also test, Test, TEST

 109 #    For every operation and attribute do
 110 #       For return val and all parameters do
 111 #       find basic IDL type for each parameter
 112 #       output get_CDR_xxx
 113 #       output exception handling code
