megaco_codec_transform

Megaco message transformation utility.

This module implements a simple megaco message transformation utility.

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

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])

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])

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

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.

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.

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).
