CARGO

Simple, stupid and portable C argument (argv) parser.

Build

Just include cargo.h to your project.

CARGO tests are built with CMake for all platforms. You can also use the fake configure script provided to set it up on unix:

$ ./configure
$ make

Doc

Depends on Doxygen.

$ make cargo_doc

Example

To handle the following program arguments:

./myprog --flag1 --flag2= --flag3=hello --flag4="Hello world"

You could write this:

[...]

int main(int argc, char* argv[])
{
    char* f1 = cargoFlag("flag1", "FALSE", argc, argv);         // f1 = "TRUE"
    char* f2 = cargoFlag("flag2", "defaultval", argc, argv);    // f2 = ""
    char* f3 = cargoFlag("flag3", "bye", argc, argv);           // f3 = "hello"
    char* f4 = cargoFlag("flag4", "Bye world", argc, argv);     // f4 = "Hello world"
    char* f5 = cargoFlag("flag5", "default", argc, argv);       // f5 = "default"
    char* f6 = cargoFlag("flag6", "FALSE", argc, argv);         // f6 = "FALSE"
