This PR adds a bunch of useful template functions from the sprig library, which makes it easier/possible to introduce more advanced logic in templates.
Fixes #177 by adding useful functions like
append
,join
, andset
.Fixes #293 by enabling templates to use a Go map object as a set (via the
set
andhasKey
functions).Fixes #323 by adding a new
getHostByName
function.The removed functions were removed because sprig offers those same functions with the same behavior. I left functions with the same name but different behavior alone to avoid breaking existing templates.
