.expand_var(string, env) ⇒ Object

Given a string and an env, replace any instance of shell-style variables with their value in the env. NOT POSIX COMPLIANT, just mostly hacky so I can get gitlab-ci.yml parsing to work properly. Required in MiniExec because of docs.gitlab.com/ee/ci/variables/where_variables_can_be_used.html#gitlab-internal-variable-expansion-mechanism
