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

#
# 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 dissector in Ethereal IP protocol anlayser.
+# as a plugin for the Ethereal IP Protocol Analyser.
#
#
# Strategy (sneaky but ...)

#
#
# TODO -- FS
-#
+#
# 1. generate hf[] data for searchable fields (but what is searchable?)
# 2. add item instead of add_text()
# 3. sequence handling [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]
+# 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)
-# 12. Implement IDL "union" code
-# 13. Implement support for plugins
+# 11. Support attributes (get/set) [started, needs language mapping option, perhaps ethereal 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 return val and all parameters do
+# 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 exception handling code
+# output attribute handling code
