envfileparser 0.0.6

A small env file parser

envfileparser

---

This package is as simple as possible to get variables from .env files or files with a similar structure.

Description

The package has no dependencies and works with files located in the same directory as the file from which the functions of this package were called.

Function get_env() takes the name of the target variable as a string and an optional second parameter - the path to the file. After that, the function returns the value of the variable also as a string.

Function get_envs() accepts a sequence of variable names as a string, and also an optional parameter-the path to the file. This function returns a list of strings that are the values of the desired variables.

By default, .env is specified as the path. Empty lines and lines without the '=' character are skipped. In addition, commenting with a prefix of the '#' character is supported.In the event that the specified variable is missing or the desired file cannot be found, the corresponding exceptions are thrown.

Getting started

---

Install envfileparser from PyPi with pip: pip install envfileparser

Usage example:

from envfileparser import get_env, get_envs

CONST_ONE = get_env('CONST1')
CONST_TWO = get_env('CONST2', file_path='configs/.env')

variables = get_envs('VAR1', 'VAR2', 'VAR3')
v1, v2, v3 = variables[0], variables[1], variables[2]

Correct .env file example:

# Service token.
API_TOKEN = f3u12yf36f12f418449go3294g238

PORT = 3417
IP = 127.0.0.1 # loopback

USER = 'ADMIN'
PASSWORD="12345678"

---

If your value contains the " # "character, then be sure to put it in quotation marks-otherwise the parser will take all subsequent characters (including the" # " character) as a comment: The .env file:

VAR1 = envfile#parser
VAR2 = "envfile#parser"

Python code:

from envfileparser import get_env, get_envs

print(*get_envs('VAR1', 'VAR2'), sep='\n')

Output:

envfile
envfile#parser
