Detailed Description

"\nThe CommandLineParser class is designed for command line arguments parsing\n" "Keys map: \n" "Before you start to work with CommandLineParser you have to create a map for keys.\n" " It will look like this\n" " const char* keys =\n" " {\n" " { s| string| 123asd |string parameter}\n" " { d| digit | 100 |digit parameter }\n" " { c|noCamera|false |without camera }\n" " { 1| |some text|help }\n" " { 2| |333 |another help }\n" " };\n" "Usage syntax: \n" " \"{" - start of parameter string.
" " "}" - end of parameter string
" " "|" - separator between short name, full name, default value and help
" "Supported syntax:
" " --key1=arg1 <If a key with '--' must has an argument
" " you have to assign it through '=' sign.>
" "<If the key with '--' doesn't have any argument, it means that it is a bool key>
" " -key2=arg2 <If a key with '-' must has an argument
" " you have to assign it through '=' sign.>
" "If the key with '-' doesn't have any argument, it means that it is a bool key
" " key3 <This key can't has any parameter>
" "Usage:
" " Imagine that the input parameters are next:
" " -s=string_value --digit=250 --noCamera lena.jpg 10000
" " CommandLineParser parser(argc, argv, keys) - create a parser object
" " parser.get<string>("s" or "string") will return you first parameter value
" " parser.get<string>("s", false or "string", false) will return you first parameter value
" " without spaces in end and begin
" " parser.get<int>("d" or "digit") will return you second parameter value.
" " It also works with 'unsigned int', 'double', and 'float' types>
" " parser.get<bool>("c" or "noCamera") will return you true .
" " If you enter this key in commandline>
" " It return you false otherwise.
" " parser.get<string>("1") will return you the first argument without parameter (lena.jpg)
" " parser.get<int>("2") will return you the second argument without parameter (10000)
" " It also works with 'unsigned int', 'double', and 'float' types
