NAME¶

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

DESCRIPTION¶

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

FILE FORMAT¶

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.

NOEMIT 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.

ETT_FIELD ett

Register a custom ett field

STRIP_PREFIX prefix

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.

FIELD_DESCRIPTION field desc

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.
