# 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.

|
|
# 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)
