Generate env requirements with the CLI

Installation

Generate env file

$ scanenv -f ./main.goENVS_ARE_FUN=""ENVS_ARE_COMPLICATED=""PORT="8080"INSECURE="Value marked as optional"

$ scanenv -d.ENVS_ARE_FUN=""ENVS_ARE_COMPLICATED=""PORT="8080"INSECURE="Value marked as optional"

Get where env is declared

$ scanenv -d. -p# ./main.goENVS_ARE_FUN=""ENVS_ARE_COMPLICATED=""PORT="8080"INSECURE="Value marked as optional"# ./util/redis.goREDIS_PORT=""

Validate .env file
