I'd like to pass parameters to my C++ program in the following manner:

./myprog --setting=value

Are there any libraries which will help me to do this easily?

Answer 1

Boost.Program_options

Answer 2

GNU GetOpt.

Answer 3

There are these tools in the GNU C Library, which includes GetOpt.

If you are using Qt and like the GetOpt interface, froglogic has published a nice interface here.

Answer 4

argstream is quite similar to boost.program_option: it permits to bind variables to options, etc. However it does not handle options stored in a configuration file.

Answer 5

And there's a Google library available.

Really, command-line parsing is "solved." Just pick one.

Answer 6

There are a couples of C++ argument parsers out there, you may want to try this one from http://clp.sourceforge.net/, very simple and convenient.

Answer 7

Try CLPP library. It's simple and flexible library for command line parameters parsing. Header-only and cross-platform. Uses ISO C++ and Boost C++ libraries only. IMHO it is easier than Boost.Program_options.

Library: http://sourceforge.net/projects/clp-parser/
