An easy to use argument parsing library, with all the features you will ever probably need.
Features:
- short and long argument names
- automatic assignment of argument values to given variables
- non-parameter arguments (switch), and arguments requiring parameter input
- (also, counting the occurence of a specific parameter, good for verbose level)
- positional arguments (at the beginning or the end of the command line)
- argument groups
- argument descriptions
- automatic usage generation, line wrapped to 120 characters
Program usage is automatically printed out in case no arguments are specified, or if an argument is misused.
Simply copy the argparser.cc and argparser.h files into your project and #include <argparser.h>.
To run an example from this repo, type:
cd src
make
./argumentparser --threads 8
An example usage code snippet.
ArgumentParser argparser;
int32_t num_threads = 0;
argparser.AddArgument(&num_threads, VALUE_TYPE_INT32, "t", "threads", "-1", "Number of threads to use.", 0, "Basic options");
printf ("num_threads = %d\n", num_threads);
A more comprehensive example can be found in example.cc.
Additionally, the code contains verbose descriptions to detail the usage.
