Hi,

On Makefile I often use a global flag/argument to control certain definitions based on my environment.

An example is to either use or not the -ti flags from docker exec:

ifeq ($(env_name),cicd)
# automated environment like Github Actions
docker_main_app_sh=docker exec my_app sh
else
# local development host
docker_main_app_sh=docker exec -ti my_app sh
endif

container_app_run_some_internal_cmd:
        $(docker_main_app_sh) -c "pwd"

and execute it as:

• make container_app_run_some_internal_cmd env_name=cicd
• make container_app_run_some_internal_cmd env_name=whatever

My question: Is it possible to recreate such logic in nushell?

if ($env_name == "cicd") {
    alias docker_main_app_sh = docker exec my_app sh
} else {
    alias docker_main_app_sh = docker exec -ti my_app sh
}

def "main container_app_run_some_internal_cmd" [] {
    docker_main_app_sh -c "pwd"
}

and execute it as:

• nu some_script.nu container_app_run_some_internal_cmd --env_name=cicd
  or maybe
• nu some_script.nu --env_name=cicd container_app_run_some_internal_cmd
