I like this patch! Do you think we could use mustache templates to inject the data?

The syntax would be exactly the same {{ value }}, but using mustache could give us more flexibility.

does this maintain compatibility with running builds directly via the drone command? is it a design goal for drone that .drone.yml files be portable for either use?

[bradrydzewski]

good point. maybe we inject local environment variables into the .drone.yml when running from the client? So I could do something like this:

AWS_KEY=xxxx AWS_SECRET=yyyy drone build

I'm going to go ahead and merge this since the syntax won't change if / when we support mustanche. I'll also think more about how this impacts drone-cli, but I don't want to hold this up in the mean time.

@afex @bradrydzewski
Thanks for your comments!
I'm now just fixing this function to use mustanche and drone-cli.
When I'll finish it, I'll send another PR.
