Re: commandline arguments using Glib::OptionEntry

Hi, Paul,

You may try boost::program_options, it is a template library in boost, which handles the program options. you can check the following links about the tutorial.

Hi Bernd,
Yes, your right I think, I will code a class as I have in Visual Studio MFC that will do everything for the commandline arguments. I went through the same thing with Windows, I looked at different options that were available and ended up having to do it all myself. I know some people are using the Glib::OptionEntry code to detect their args, others use getopt, and others use completely custom code. I like your vector idea, I plan to try using that!

Hello Paul,

you can use the options as in any other C++ application.
You can derefence it through the "char**" parameter of the main

For expampe:

# progname -n para1,para2,para3,para4

You would check in your application for the "-n" parameter wich would be
found in this exampla in "char[1]" and then you can reach the "paraX"
over "char[2]".

The above example would store the parameter as:

"progname" = argc = 1 = argv[0]
"-n" = argc = 2 = argv[1]
"para1,para2..." = argc = 2 = argv[2]

So argv[2] IS already a char-string.

For example you could cast it to a Glib::ustring and search/replace by
the "," and store them in a vector or something Gtkmm equivalent
(perhaps as an own class or function). After that, you can pass it as a
parameter to your class wich builds the OptionEntry and work with your
vectorized data.

If I have to deal with cli parameter, I often do it like this way
depends on what I need. It works for me.
