Boot Environment

Note: This document describes features that have not yet been merged with the master branch. This is a preview of the 2.0.0-rc1 release.

The boot environment contains the current JVM classpath configuration state.

(get-env)

Returns the whole environment map.

(get-env key)

Returns the value associated with the given key, or nil if the key is not found.

(get-env key not-found)

Returns the value associated with the given key, or not-found if the key is not found.

(set-env! key val & kvs)

Sets the values for the given keys. Note that this may produce side effects, changes to the JVM's classpath, etc.

Note: Env settings must be printable and writable–the env must be able to be passed to Pods to configure them, so the env map must always be able to be round-tripped through pr-str and read-string.

Replace Env Setting With New Value

(set-env! :source-paths #{"foo" "bar"})

Update Env

(set-env! :source-paths #(conj % "baz"))
