Bepartofyou / gengetopt

using gengetopt to parser cmd arguments

first you should install gengetopt and cmake

centOS

sudo yum install gengetopt cmake

ubuntu

sudo apt-get install gengetopt cmake

step into project dir (gengetopt)

if only using on unix, you can exec this cmd to generate 'cmdline.c' with include <getopt.h>

gengetopt -i ./doc/test.ggo --output-dir=./src/ 

if you want to use on unix and windows, you should add an argument '-G',this will generate internal getopt_long function without needing include <getopt.h> in 'cmdline.c'

gengetopt -i ./doc/test.ggo --output-dir=./src/ -G

after exec this cmd, you can find 'cmdline.c' and 'cmdline.h' files in src dir.

out-of-source build

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug ../
make

test the function in build dir

./test -h

you can see the stdout like this:

Bepartofyou 1.2.3
purpose: This is a demo to understand gengetopt functon
Usage: To generate cmd parser
description: Bepartofyou is a hansome man!    Define three type 
varible(flag/bool int string). In cmds, 'b' is short for 'daemon'; 'c' is short 
for 'config' and 'l' is short for 'level'. 
-h, --help          Print help and exit
-V, --version       Print version and exit
-b, --daemon        Launch Bepartofyou in background as a daemon<br>
						(default=off)
-c, --config=path   config file path (default=none)
-l, --level=number  Bepartofyou hansome levels (default=0)
