obj-cli

Object Oriented Command Line Interface Library of C++

Introduce

This is used to handle command line input. Programers can write a struct to describe the input and accord function, Despite the getopt process and error handler

Example

    make
    ./objcli node set --meta=hank
    ./objcli node get --meta=hank

Usage

First, define a Request struct, include all possible parameters

Second, define a Context class, include the

Thirdly, define the class and actions of the cli

Finally, call CliInvoke to parse request and execute actions.

Here are some example:

Simple

    #include <obj-cli.h>
    struct Request{
            CLI_DECLARE(param1);
            CLI_DECLARE(param2);
    }
    struct Context{
            const char *password;
    }
    int func_dummy1(Request &, Context *){
            return 0;
    }
    int func_dummy1(Request &, Context *){
            return 0;
    }
    CliObject<Request,Context> meta[] = {
            {
                    "class1", {
                            {
                                    "action1",
                                    func_dummy,
                                    {
                                    }
                            },
                                    "action2",
                                    func_dummy2,
                                    {
                                    }
                            }
                    }
            }, {
                    "class2",{
                    }
            }
    };
    // ./a.out class1 action1 --param1=a --param2=b
    // ./a.out class1 action2 --param2=a
    int main(int argc, const char *argv[]) {
            return CliInvoke<Request, Context>(argc, argv, meta, 3);
    }

Advanced

    int main(int argc, const char* argv[]) {
            Request request;
            Context context;
            InvokeContext<Request, Context> env(argv[0], g_meta, meta_num, g_opt, opt_num);
            int ret = CliParse(argc, argv, request, env);
            if(0 != ret){
                    return ret;
            }
            if(0 != strcmp(request.password, "secret")){
                    return -1;
            }
            context.password = "holy pot";
            return CliInvoke(request, context, env);
    }

AutoComplete

Besides, this program supplies auto-complete functions.

Users can use to call the program give Tips.

example

    ./objcli node <Tag>
    set get
