How to use it in your devShell.

1. Add it to inputs in your flake.nix file.

inputs = {
    nixpkgs.url = "nixpkgs/nixos-24.05";
    libgets = {
        url = "github:aldosierra/libgets";
        inputs.nixpkgs.follows = "nixpkgs";
    };
};

2. Add it to the devShell buildInputs.

devShells = {
    default = pkgs.mkShell {
        name = "sample-env";
        buildInputs = with pkgs; [ gcc libgets.packages."x86_64-linux".default ];
    };
};

3. Import it on your c file.

#include "libgets.h"

int main(void) {
    char *name = GetString("What is your name? ");
    printf("Hi, %s\n", name);

    return 0;
}

Optionally you can add libgets to C_INCLUDE_PATH to include it on the standard system include directories, here is an example.

devShells = {
    default = pkgs.mkShell {
        name = "sample-env";
        buildInputs = with pkgs; [ gcc libgets.packages."x86_64-linux".default ];
        C_INCLUDE_PATH = "${libgets.packages.${system}.default}/include:$C_INCLUDE_PATH";
    };
};

This will work with both #include <...> and #include "...".

#include <libgets.h>

int main(void) {
    char *name = GetString("What is your name? ");
    printf("Hi, %s\n", name);

    return 0;
}

To do List.

• Add a list of functions include it on this library.
• Add options parameters for format messages.
• Check for missing functions on the og cs50 library.
