read_env: Read environment variables from a file

In rcdf: A Comprehensive Toolkit for Working with Encrypted Parquet Files

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. The function also removes quotes ('"') around values if present.

Usage

read_env(path)

Arguments

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

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.

Examples

## Not run: 
# 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()

## End(Not run)
