| The `args` property allows to explicitly set arguments for the execution. The
 | |
| name of the executable will always be the first element in the arg-vector.
 | |
| 
 | |
| \section args_details Details
 | |
| 
 | |
| \subsection args_operations Operations
 | |
| 
 | |
| \subsubsection args_set_var Setting values
 | |
| 
 | |
| To set a the argument vector the following syntax can be used.
 | |
| 
 | |
| \code{.cpp}
 | |
| args = value;
 | |
| args(value);
 | |
| \endcode
 | |
| 
 | |
| `std::initializer_list` is among the allowed types, so the following syntax is also possible.
 | |
| 
 | |
| \code{.cpp}
 | |
| args = {value1, value2};
 | |
| args({value1, value2});
 | |
| \endcode
 | |
| 
 | |
| Below the possible types for `value` are listed, with `char_type` being either `char` or `wchar_t`.
 | |
| 
 | |
| \paragraph args_set_var_value value
 | |
| 
 | |
|  - `std::basic_string<char_type>`
 | |
|  - `const char_type * `
 | |
|  - `std::initializer_list<const char_type *>`
 | |
|  - `std::vector<std::basic_string<char_type>>`
 | |
| 
 | |
| Additionally any range of `std::basic_string<char_type>` can be passed.
 | |
| 
 | |
| \subsubsection args_append_var Appending values
 | |
| 
 | |
| To append a the argument vector the following syntax can be used.
 | |
| 
 | |
| \code{.cpp}
 | |
| args += value;
 | |
| \endcode
 | |
| 
 | |
| `std::initializer_list` is among the allowed types, so the following syntax is also possible.
 | |
| 
 | |
| \code{.cpp}
 | |
| args += {value1, value2};
 | |
| \endcode
 | |
| 
 | |
| Below the possible types for `value` are listed, with `char_type` being either `char` or `wchar_t`.
 | |
| 
 | |
| \paragraph args_append_var_value value
 | |
| 
 | |
|  - `std::basic_string<char_type>`
 | |
|  - `const char_type * `
 | |
|  - `std::initializer_list<const char_type *>`
 | |
|  - `std::vector<std::basic_string<char_type>>`
 | |
| 
 | |
| Additionally any range of `std::basic_string<char_type>` can be passed.
 | |
| 
 | |
| 
 | |
| \subsection args_example Example
 | |
| 
 | |
| The overload form is used when more than one string is passed, from the second one forward.
 | |
| I.e. the following expressions have the same results:
 | |
| 
 | |
| \code{.cpp}
 | |
| spawn("gcc", "--version");
 | |
| spawn("gcc", args ="--version");
 | |
| spawn("gcc", args+="--version");
 | |
| spawn("gcc", args ={"--version"});
 | |
| spawn("gcc", args+={"--version"});
 | |
| \endcode
 | |
| 
 | |
| \note A string will be parsed and set in quotes if it has none and contains spaces.
