# megaco_codec_transform

### MODULE

megaco_codec_transform

### MODULE SUMMARY

Megaco message transformation utility.

### DESCRIPTION

This module implements a simple megaco message transformation utility.

Note that this module is not included in the runtime part of the application.

### EXPORTS

tt() -> void()

Transform messages using pretty text as base. Transform messages from pretty text encoding to compact, ber, per and erlang encoding.

This call is equivalent to the call: t(pretty, [compact, ber, per, erlang])

tb() -> void()

Transform messages using ber binary as base. Transform messages from ber binary encoding to pretty, compact, ber, per and erlang encoding.

This call is equivalent to the call: t(ber, [pretty, compact, per, erlang])

t([FromCodec, ToCodecs]) -> ok | {error, Reason}

Types:

FromCodec = codec_string()
ToCodecs = [codec_string()]
codec_string() = "pretty" | "compact" | "ber" | "per" | "erlang"

Called from the command line (shell) to transform all messages in a given codec dir to a given list of codec dirs. The dirs will not be created.

Example: Converts from codec ber to codecs pretty, compact and per

              erl -noshell -sname megaco ../ebin \
                  -run megaco_codec_transform t ber "pretty compact per" \
                  -s erlang halt

t(FromCodec, ToCodecs) -> ok | {error, Reason}

Types:

FromCodec = codec()
ToCodecs = [codec()]
codec() = pretty | compact | ber | per | erlang

Transforms all messages in a given codec dir to a given list of codec dirs. The dirs will not be created.

tmf(FromFile, FromCodec, ToCodec) -> ok | {error, Reason}

Types:

FromFile = string()
FromCodec = codec()
ToCodec = codec()

Transform a message in a file encoded with the given codec to another codec. The resulting message is written to file, in the ToCodec dir.

tm(FromMsg, FromCodec, ToCodec) -> binary()

Types:

FromMsg = binary()
FromCodec = codec()
ToCodec = codec()

Tranforms a message binary encoded with the given codec to another codec. The resulting message is returned (as a binary).
