Am seriosuly hacking away at

And I wannt to switch between the current version and next mixed version

Impossible..

So maaybe the next version is the one where we can make this possible..

You can easily switch between versions by adjusting your gopath ev,

Open two shells
Specify different gopaths and fetch revel in each
In one of the paths modify the checked out branch to develop for all revel repositories (git checkout -b develop), recompile (go build github.com/revel/cmd)
Now append your project path to each of the gopaths in the shells - or if your lazy symlink it.
Now you can test your app in both environments by running it in the appropriate shell window.

I would say nay to adding this to revel though, there is simply to many variables to control

@pedromorgan Check this:

go get github.com/anonx/revdev

Use the following commands in your shell:

• revdev on to switch to develop branch
• revdev off to switch back to master

Everything will be checked out automatically and revel cmd will be recompiled.

(It doesn't clone anything, so make sure you have modules, samples, revel, and cmd & all of them have master/develop branches)

I like @AnonX's solution. Anything beyond that could get complex as @notzippy said.

Once again with a monthly release cycle as a goal I am closing this issue as unnecessary.
