Create a more modular type system for the FT_* types. Put them into epan/ftypes. Re-write display filter routines using Lemon parser instead of yacc. Besides using a different tool, the new grammar is much simpler, while the display filter engine itself is more powerful and more easily extended. Add dftest executable, to test display filter "bytecode" generation. Add option to "configure" to build dftest or randpkt, both of which are not built by default. Implement Ed Warnicke's ideas about dranges in the new display filter and ftype code. Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree, while FT_PROTOCOL is used for protocols. This was necessary for being able to make byte slices (ranges) out of protocols, like "frame[0:3]" Win32 Makefile.nmake's will be added tonight. svn path=/trunk/; revision=2967 2001-02-01 20:21:25 +00:00			`#ifndef GENCODE_H`

Provide for per-protocol-tree data in the proto_tree code. Put a hash-table of "interesting" fields in the per-proto-tree data. The dfilter code records which fields/protocols are "interesting" (by which I mean, their value or existence is checked). Thus, the proto_tree routines can create special arrays of field_info's that are ready for the dfilter engine to use during a filter operation. Also store the "proto_tree_is_visible" boolean, renamed "visible", in the per-proto-tree data. Move epan_dissect_t to its own header file to make #include dependencies easier to handle. Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t as an argument. epan_dissect_new() needs to be followed by epan_dissect_run() for the dissection to actually take place. Between those two calls, epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to prime the empty proto_tree with the "intersesting" fields from the dfilter_t. svn path=/trunk/; revision=4422 2001-12-18 19:09:08 +00:00			`int*`
