36 /** \defgroup senf_console_utilities Special console utility types
38 These types are provided by the %console library to support special argument or return value
45 /** \brief Parse character value as single-char string
47 This helper types is a wrapper around \a CharT which must be a character type. A value of
48 this type will be represented as a single character string, not as numeric value (the
49 default interpretation of char arguments in the console library).
51 This wrapper is used via type conversion using \c boost::function to convert the
52 argument/return type \a CharT to CharAsString<CharT>:
54 char foo(char v) { return v; }
56 senf::console::root().add(
57 "foo", boost::function< CharAsString<char> (CharAsString<char>) >(&foo));

133 /** \brief Bit-mask flag argument type
135 senf::console::FlagCollection supplies a special argument type for use in registering
136 console commands. This argument type is used to represent a bit-mask of single flags.
139 // Function taking a flags argument
140 void func(unsigned flags);
142 // Enum containing all the possible flag values
143 enum MyFlags { Foo = 1,
147 SENF_CONSOLE_REGISTER_ENUM(MyFlags, (Foo)(Bar)(Baz)(Boo));
149 // Register the function with a FlagCollection argument type
150 consoleDir.add("func", boost::function<void (FlagCollection<MyFlags>)>(&func));
153 To use the FlagCollection class
154 \li you need a function which takes a bit-mask of flags as argument
155 \li you define and register an enum with all possible flag values
156 \li you register the function with a FlagCollection argument type using \c boost::function
157 for the conversion. This is also possible for return values.
159 The nice thing is, that \c boot::function supports compatible argument types and does
160 automatic type conversion. Since a FlagCollection is convertible to and from unsigned long,
161 this conversion will work.
163 After registering this function, you can call it with a collection of flags as argument
170 console:/$ func (Foo Boo)
