QuickFIX/Go

Open Source FIX Protocol library implemented in Go

Getting Started and Documentation

Installation

To install QuickFIX/Go, use go get:

$ go get github.com/alpacahq/quickfix
Staying up to date

To update QuickFIX/Go to the latest version, use go get -u github.com/alpacahq/quickfix.

Example Apps

See examples for some simple examples of using QuickFIX/Go.

FIX Message Generation

QuickFIX/Go includes separate packages for tags, fields, enums, messages, and message components generated from the FIX 4.0 - FIX5.0SP2 specs. See:

For most FIX applications, these generated resources are sufficient. Custom FIX applications may generate source specific to the FIX spec of that application using the generate-fix tool included with QuickFIX/Go.

Following installation, generate-fix is installed to $GOPATH/bin/generate-fix. Run $GOPATH/bin/generate-fix --help for usage instructions.

Developing QuickFIX/Go

If you wish to work on QuickFIX/Go itself, you will first need Go installed on your machine (version 1.6+ is required).

For local dev first make sure Go is properly installed, including setting up a GOPATH.

Next, using Git, clone this repository into $GOPATH/src/github.com/alpacahq/quickfix.

Installing Dependencies

QuickFIX/Go uses dep to manage the vendored dependencies. Install dep with go get:

$ go get -u github.com/golang/dep/cmd/dep

Run dep ensure to install the correct versioned dependencies into vendor/, which Go 1.6+ automatically recognizes and loads.

$ $GOPATH/bin/dep ensure

Note: No vendored dependencies are included in the QuickFIX/Go source.

Build and Test

The default make target runs go vet and unit tests.

$ make

If this exits with exit status 0, then everything is working!

Generated Code

Generated code from the FIX40-FIX50SP2 specs are available as separate repos under the QuickFIX/Go organization. The source specifications for this generated code is located in spec/. Generated code can be identified by the .generated.go suffix. Any changes to generated code must be captured by changes to source in cmd/generate-fix. After making changes to the code generator source, run the following to re-generate the source

$ make generate-dist

If you are making changes to the generated code, please create Pull Requests for these changes for the affected repos.

Acceptance Tests

QuickFIX/Go has a comprehensive acceptance test suite covering the FIX protocol. These are the same tests used across all QuickFIX implementations.

QuickFIX/Go acceptance tests depend on ruby in path.

To run acceptance tests,

    # generate code locally
    make generate

	# build acceptance test rig
	make build_accept

	# run acceptance tests
	make accept
Dependencies

If you are developing QuickFIX/Go, there are a few tasks you might need to perform related to dependencies.

Adding a dependency

If you are adding a dependency, you will need to update the dep manifest in the same Pull Request as the code that depends on it. You should do this in a separate commit from your code, as this makes PR review easier and Git history simpler to read in the future.

To add a dependency:

  1. Add the dependency using dep:
$ dep ensure -add github.com/foo/bar
  1. Review the changes in git and commit them.
Updating a dependency

To update a dependency to the latest version allowed by constraints in Gopkg.toml:

  1. Run:
$ dep ensure -update github.com/foo/bar
  1. Review the changes in git and commit them.

To change the allowed version/branch/revision of a dependency:

  1. Manually edit Gopkg.toml
  2. Run:
$ dep ensure
  1. Review the changes in git and commit them.
