venv

Simple .env parser and loader for VLang projects.

Install

v install TheBoringDude.venv

What it does?

Loads the variables configured from your .env file in your root project and adds them to the os.environ

Usage

import theboringdude.venv

import os

fn main() {
    // run first the function
    // if you want to have some configurations, use `venv.load_env_conf(LoaderConfig)`
    venv.load_env()
    // if you want to overwrite the variables
    // use `venv.load_env(overwrite: true)`
    // you can also just use `venv.load_env({})`
    //  this will default to true

    // you can now access your variables
    // from the `.env` file
    println(os.getenv('My_VARIABLE'))
}

Functions

venv.load_env

• Loads .env file using the default configurations.

venv.load_env_conf(LoaderConfig)

• Loads .env file with configurations.

  LoaderConfig

  pub struct LoaderConfig {
      overwrite bool = true // custom default to true
      uppercase bool = true // convert env keys to uppercase
  }
  

Custom getenv

// you can use venv's custom getenv to automatically convert vars
//  to their respective vars

println(venv.getenv_bool("BOOL")) // bool env var value
println(venv.getenv_int("NUM")) // int env var value
println(venv.getenv_float("FLOAT")) // float env var value

.env Structure

I do not want to complicate a simple utility. It just parses the common .env structure like, ..

# this is some comment
// you can do anything
#### but if `=` is detected, the line will be parsed
HELLO=WORLD
