provide params on command line

[yegor256]

I'm trying to use dandelion together with Travis-CI, in order to deploy my public (!) repository through FTP to my private server. I can't do it at the moment, because I have to hard-code FTP password inside dandelion.yml file. That means that my FTP credentials will be publicly available in Github.

Instead, would be great to have an ability to run:

dandelion deploy -Dpassword=secret123

Then, in dandelion.yml I will use:

password: ${password}

Instead of creating separate command-line options for each config parameter would environment variables do the trick?

I'm thinking that dandelion.yml could be interpreted as ERB so you could write:

password: <%= ENV['DANDELION_PASSWORD'] %>

And then run:

DANDELION_PASSWORD=secret123 dandelion deploy

Would that satisfy your use case?

[yegor256]

yes, that will be even better

This is in v0.4.4

Can this be added to the readme? It's pretty useful info.

@Polymetric Good call. Added this to the README (https://github.com/scttnlsn/dandelion/commit/58b4c21e91456d0e0f96affe3205a3054195f232)
