pallet.environment
The environments provide mechanisms for customising Pallet and Pallet crates according to externally determined criteria.
An environment can be specified at the global, service, invocation and tag scopes.
To provide a global default, specify an :environment key at the top level
of defpallet in ~/.pallet/config.clj.
To provide a service specific default, specify an :environment key at the
service level of defpallet in ~/.pallet/config.clj.
To provide a project specific default, define pallet.config/environment.
To provide a specific environment when invoking lift or converge, pass an
environment map using the :environment key.
The merging of values between scopes is key specific, and is determined by
merge-key-algorithm.
The environments provide mechanisms for customising Pallet and Pallet crates according to externally determined criteria. An environment can be specified at the global, service, invocation and tag scopes. To provide a global default, specify an `:environment` key at the top level of `defpallet` in `~/.pallet/config.clj`. To provide a service specific default, specify an `:environment` key at the service level of `defpallet` in `~/.pallet/config.clj`. To provide a project specific default, define `pallet.config/environment`. To provide a specific environment when invoking `lift` or `converge`, pass an environment map using the `:environment` key. The merging of values between scopes is key specific, and is determined by `merge-key-algorithm`.

Evaluate an environment literal. This is used to replace certain keys with objects constructed from the map of values provided. The keys that are evaluated are: - `:user` - `:phases` - `:algorithms`
get-environmentclj
(get-environment keys)(get-environment keys default)Environment accessor.
Environment accessor.
group-with-environmentclj
(group-with-environment environment group)Add the environment to a group.
Add the environment to a group.
merge-environmentsclj
(merge-environments & maps)Returns a map that consists of the rest of the maps conj-ed onto
the first. If a key occurs in more than one map, the mapping(s)
from the latter (left-to-right) will be combined with the mapping in
the result by calling (merge-key key val-in-result val-in-latter).
