/**
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.
