This small package adds support for loading .env files. Just call the env_load function with a valid path, that contains a file named .env, or the path of the env file itself. If can't be loaded, it'll return -1, 0 otherwise. If the second parameter is set to true, already existing environment variable will be replaced with the new value.

In the file, comments can be added by starting the line with #. It's also possible to nest the variables, but in that case, the used variables need be already defined.

Quotes won't be removed from the strings.

# Build
(mkdir -p build && cd build && \
cmake .. && cmake --build .)
# Optional install
sudo make install

mkdir -p build && cd build && \
cmake -DCMAKE_BUILD_TYPE=DEBUG -DDOTENV_TEST=ON .. && cmake --build . && \
cd .. && ./build/dotenv-test) 

Install via clib: clib install Isty001/dotenv-c, or just git clone into your project.

Or if you don't want to include in your project, you can git clone then install by executing make install then link it with -ldotenv.

# DB connection
DB_HOST=localhost
DB_NAME=test_db

    env_load(".", false);
    char *connection = getenv("DSN");
