I am fairly new to golang, and trying to identify the best tools for the job. Currently I am evaluating the following packages:
https://github.com/mattes/migrate
https://github.com/DavidHuie/gomigrate
https://bitbucket.org/liamstask/goose/
I was wondering if anyone had any experience with these (or other packages) and could provide some comments.
We use mattes/migrate at work and are very happy with it. It works with plain SQL files, handles file naming by itself and can easily be automated via CLI. It doesn't do anything Go specific.
With gomigrate you need to create the files yourself and write code for executing the migrations.
Take a look at https://github.com/pressly/goose, a maintained fork of https://bitbucket.org/liamstask/goose/.

What are the available open source quickfix acceptors/servers/simulators which have MATCHING and EXECUTION option. If you any tool please give the link.
I found few tools like fiximulator,quickfix-messenger and ect. But these tools don't have order matching option.
Thanks in advance.
QuickfixJ comes with an example called OrderMatcher. It is a simple order matching engine that accepts orders and generated ER when matches occurs.

Is it possible to automate the documentation of routes in a Spray application?
e.g. Is there perhaps an SBT plugin that generates markdown describing what it knows about the spray routes?
I stumbled upon spray-swagger while researching the same thing but I don't know exactly what it does and which stage the project is at.
