Parse::Pidl::Wireshark::Conformance - Conformance file parser for Wireshark


This module supports parsing Wireshark conformance files (*.cnf).


Pidl needs additional data for Wireshark output. This data is read from so-called conformance files. This section describes the format of these files.

Conformance files are simple text files with a single command on each line. Empty lines and lines starting with a '#' character are ignored. Arguments to commands are separated by spaces.

The following commands are currently supported:

TYPE name dissector ft_type base_type mask valsstring alignment
Register new data type with specified name, what dissector function to call and what properties to give header fields for elements of this type.
Suppress emitting a dissect_type function for the specified type
PARAM_VALUE type param
Set parameter to specify to dissector function for given type.
HF_FIELD hf title filter ft_type base_type valsstring mask description
Generate a custom header field with specified properties.
HF_RENAME old_hf_name new_hf_name
Force the use of new_hf_name when the parser generator was going to use old_hf_name.

This can be used in conjunction with HF_FIELD in order to make more than one element use the same filter name.

Register a custom ett field
Remove the specified prefix from all function names (if present).
PROTOCOL longname shortname filtername
Change the short-, long- and filter-name for the current interface in Wireshark.
Change description for the specified header field. `field' is the hf name of the field.
IMPORT dissector code...
Code to insert when generating the specified dissector. @HF@ and @PARAM@ will be substituted.
INCLUDE filename
Include conformance data from the specified filename in the dissector.
TFS hf_name "true string" "false string"
Override the text shown when a bitmap boolean value is enabled or disabled.
MANUAL fn_name
Force pidl to not generate a particular function but allow the user to write a function manually. This can be used to remove the function for only one level for a particular element rather than all the functions and ett/hf variables for a particular element as the NOEMIT command does.
CODE START/CODE END Begin and end a section of code to be put directly into the generated source file for the dissector.
HEADER START/HEADER END Begin and end a section of code to be put directly into the generated header file for the dissector.
