read_env: Read environment variables from a file

Description

Reads a .env file containing environment variables in the format KEY=VALUE, and returns them as a named list. Lines starting with # are considered comments and ignored.

Usage

read_env(path)

Value

A named list of environment variables. Each element is a key-value pair extracted from the file. If no variables are found, NULL is returned.

Arguments

path

A string specifying the path to the .env file. If not provided, defaults to .env in the current working directory.

Examples

if (FALSE) {
# Assuming an `.env` file with the following content:
# DB_HOST=localhost
# DB_USER=root
# DB_PASS="secret"

env_vars <- read_env(".env")
print(env_vars)
# Should output something like:
# $DB_HOST
# [1] "localhost"

# If no path is given, it defaults to `.env` in the current directory.
env_vars <- read_env()
}
