Dotenvarus

📑 A simple to use library to fetch local .env variables.

Building

In order to build dotenvarus, you are going to need the following dependencies:

  • gcc
  • meson
  • ninja

And then you should remove any leftover build folders, at the root path of the project.

rm -rf build

Create the folder again:

mkdir buid

Go into it:

cd build

Prepare the build with meson:

meson ..

Run ninja!

ninja

Then, if everything went as expected, you should see three files inside the build folder. Namely:

  • dotenvarus_test - The test executable
  • libdotenvarus.a - Static library
  • libdotenvarus.so - Dynamic library

In order to link a project with the static library for example, you should copy dotenvarus.h and libdotenvarus.a to your project folder.
With the examples folder, we can copy these files and then simply run gcc example.c libdotenvarus.a and the output a.out should be linked with the library.

Usage

You can change the name of the env file by changing the value of ENV_FILE preprocessor.

There are basically three methods that can be called:

  • set_env_path - set a path to ENV_FILE
  • get_env_path - returns the path that will be appended when looking for ENV_FILE
  • get_var - retrieves a value from the specified environment variable inside ENV_FILE
