[ G++-5/6/7 ]

Simple parser to split a command line string into its components, like you'll find them in argv. Splits on whitespace and keeps quoted parts together. Supports single and double quotes; quotes can be nested (one level, eg: "foo 'bar'") and will not be treated as quotes if escaped by a backslash (\" or \').
Tests are in tests directory and use CMake-integrated testing; call make all and make test.

Header only. Include and use as shown. Parameter to the constructor can be omited, but your arguments array will be missing the program name; you can allway specify it explicitly in your arguments string.

argv_parser parser("programm_name");
parser.parse("-p \"my flag param\" --switch='switch value'");
const char** my_argv = parser.argv();

Uses CMake-integrated testing: Tests are configured in tests/CMakeLists.txt, using the provided function add_cmdline_test( <test_name> "<quoted command line string>" ). This will generate a test-units C++ code, including the given string of arguments. On execution, the arguments given on the command line and the arguments extracted from the given string are compared - test passes if they match.
