fix-orchestra-protobuf's Introduction

fix-orchestra-protobuf

Translators from FIX Orchestra to the protobuf family of serializations.

Supported Serializations

  • Protocol Buffers ver 2
  • Protocol Buffers ver 3
  • Cap'n Proto

Generation of schema files is based on Encoding FIX using GPB Release Candidate 3 specifications. Note that generation of .capnp files is also based on this spec and is done so without much consideration of the differences between the two encodings. I.e. there may be other ways to generate .capnp files to better leverage Cap'n Proto's efficiencies.

Prerequisites

Build

The project is built with Maven version 3.0 or later.

Usage

java -jar orchestra2proto-jar-with-dependencies.jar [options] orchestra_file

Options:
-altfs         Use alternate output file packaging
-help          Print this message
-lang <arg>    Schema language (valid args: proto2 proto3 capnp)
-nosort        Maintain repo field ordering
-opath <arg>   Output directory
-version       Print version

fix-orchestra-protobuf's Issues

Unexpected element exception from file geneated from playlist

I generated a orchestra file using the playlist app, and it contains a namespace that causes the generator to crash.

Exception in thread "main" java.lang.RuntimeException: XML Validation Exception: unexpected element (uri:"http://fixprotocol.io/2022/orchestra/appinfo/fixml", local:"FIXMLencodingType"). Expected elements are <{}text> at row: 19353 column: 51

The namespace is used in these structures for example:

<fixr:field id="8" abbrName="BeginString" updated="FIX.Latest" type="BeginStringCodeSet" name="BeginString" updatedEP="270" added="FIX.2.7"> <fixr:annotation> <fixr:documentation purpose="SYNOPSIS"> Identifies beginning of new message and session protocol version by means of a session profile identifier (see FIX Session Layer for details). ALWAYS FIRST FIELD IN MESSAGE. (Always unencrypted).</fixr:documentation> <fixr:appinfo purpose="FIXML"> <fixml:FIXMLencodingType notReqXML="1"/> </fixr:appinfo> </fixr:annotation> </fixr:field>

<fixr:componentRef updatedEP="192" id="1021" updated="FIX.5.0SP2" added="FIX.4.4"> <fixr:annotation> <fixr:appinfo purpose="FIXML"> <fixml:FIXMLencodingType inlined="1"/> </fixr:appinfo> <fixr:documentation> Required if NoUnderlyings(711) &gt; 0.</fixr:documentation> </fixr:annotation> </fixr:componentRef>

Errors using this repository alongside the FIXTradingCommunity/orchestrations repository

Hi, I'm experimenting with using this repository alongside the FIX standard orchestration files in the orchestrations repository to generate proto3 files. When I try to run for instance

java -jar target/orchestra2proto-jar-with-dependencies.jar  -lang proto3 ~/orchestrations/FIX\ Standard/OrchestraFIXLatest.xml

I get the following error:

Exception in thread "main" java.lang.RuntimeException: XML Validation Exception: unexpected element (uri:"http://fixprotocol.io/2022/orchestra/appinfo/fixml", local:"FIXMLencodingType"). Expected elements are <{}text> at row: 20 column: 62

Are there some other steps I need to follow for this to work?
