-[section:expression_transformation Expression Transformation: Semantic Actions]
-[/============================================================================]
-
-Sometimes, rather than immediately executing an expression template, you'd like to
-transform it into some other object. Maybe the transformation is simple, like
-converting all references into values. Maybe it's complicated, like transforming an
-expression template into a finite-state automata for matching a regular expression.
-Proto provides a framework for applying tree transformations and several canned
-transformations that are generally useful.
-
-[/===============]
-[heading Overview]
-[/===============]
-
-Defining tree transformations involves defining the grammar for your DSEL
-and decorating it with transformations. Each rule in your grammar will
-have an associated transform describing how sub-expressions matching that rule
-are to be transformed. Just as the grammar is defined recursively, so too
-is the tree transformation.
-
-You associate transforms with your grammar rules using _when_. For instance,
-you might want to promote all `int` terminals to `long`. You would say the
-following:
-
- proto::when< proto::terminal<int>, proto::terminal<long>::type(proto::_value) >
-
-`proto::terminal<long>::type(proto::_value)` is an example of a Proto transform. It
-says to create an object of type `proto::terminal<long>::type` and initialize it
-with the result of the `proto::_value` transform. `proto::_value` is a transform
-defined by Proto which extracts the value from a terminal expression.
-
-[note The transform above might look a little strange at first. It appears
-to be constructing a temporary object in place. In fact, it is a
-/function type/. Since `proto::terminal<long>::type` and `proto::_value`
-are types, `proto::terminal<long>::type(proto::_value)` is actually the type
-of a function that takes `proto::_value` as a parameter and returns
-`proto::terminal<long>::type`. But no such function actually exists! Rather,
-Proto interprets this function type as a transform, the effect of which is
-described above. The resemblance to an in-place construction of a temporary
-object is intentional. It is a concise and natural notation for specifying
-transforms. Proto transforms use function types extensively, as we'll see.]
-
-A grammar decorated with transforms is a function object that takes three
-parameters:
-
-* `expr` -- the Proto expression to transform
-* `state` -- an optional initial state for the transformation
-* `data` -- any optional mutable state information
-
-Many transforms do no use the state and data parameters, and you can pass
-dummy values for them or leave them off entirely. Later on we'll describe
-the difference between them and see where they are useful.
-
-In addition to being a function object, a grammar decorated with transforms
-is also a grammar. That is, it can be used as the second parameter to
-the _matches_ metafunction to see if an expression type matches the grammar.
-
-The first pararameter to the transform, `expr`, is a Proto expression. Its
-type /must/ match the grammar defined by the transform. It is an error to
-apply a transform to an expression that does not match the transform's
-grammar. If you try it, you're likely to get an ugly compiler error if you're
-lucky. If you're unlucky, it'll compile and do something weird at runtime.
-For instance, consider the following:
-
- // A grammar that matches an int terminal, and a
- // transform that promotes it to a long terminal.
- typedef
- proto::when<
- proto::terminal<int>
- , proto::terminal<long>::type(proto::_value)
- >
- Promote;
-
- // A character terminal
- proto::terminal<char>::type a = {'a'};
-
- // ERROR! The Promote transform expects an integer
- // terminal, not a character terminal.
- Promote promote;
- proto::terminal<long>::type i = promote(a);
-
-Grammars with transforms are proper function objects, so you can use
-`boost::result_of<>` to calculate their return types. So, applying a
-transform typically looks like this:
-
- // Assuming we have an expression to transform,
- // an initial state, and some auxiliary data ...
- Expr expr;
- State state;
- Data data;
-
- // ... calculate the result type of applying
- // Grammar's transform ...
- typedef typename
- boost::result_of<Grammar(Expr, State, Data)>::type
- result_type;
-
- // ... and apply Grammar's transform:
- result_type result = Grammar()(expr, state, data);
-
-[/====================================]
-[heading The State and Data Parameters]
-[/====================================]
-
-So in a transform, what are the `state` and `data` parameters used for?
-If you are familiar with the `std::accumulate()` standard algorithm,
-you know that it takes an input sequence, an initial state, and a
-binary function. The algorithm passes the initial state and the first
-element to the binary function to calculate a new state, which is
-then similarly combined with the second element, and so on. Users of
-functional programming languages know this operation as `fold`.
-
-Proto provides several variants of a `fold` transform that behaves
-analogously to `std::accumulate()`. The `fold` transform is described
-in detail later, but here we're just interested in the `state`
-parameter. Any transform that uses `fold` is going to require you
-to pass an initial state. That is what the second parameter of a
-transform is used for.
-
-The `data` parameter is a little different. It can be anything you
-want, and -- unlike the `state` parameter -- none of Proto's built-in
-transforms will touch it. Also unlike the `state` parameter, the
-`data` parameter will be passed around by non-const reference. You
-can use the `data` parameter to pass along data that your
-custom transforms might use or mutate.
-
-So the difference between `state` and `data` is that `state` is an
-accumulation variable that Proto will change, both in type and in
-value, during the transformation, whereas `data` is just a blob of
-bits that you would like available to your transforms. For instance,
-you might want to fold an expression tree to a Fusion list and do
-something locale-specific to each element before you put it in the
-list. In that case, your state parameter would be `fusion::nil`
-(i.e., an empty list), and the data parameter would be a
-`std::locale`.
-
-[/==========================================]
-[section Example: Calculator Arity Transform]
-[/==========================================]
-
-Let's have another look at our trusty calculator example. If you recall, the
-calculator allows the lazy evaluation of arithmetic expressions, with
-placeholders substituted with actual values provided at evaluation time. Valid
-expressions are of the form:
-
- (_1 + 3)
- (_2 - _1) / _2 * 100
-
-... and so on. In the first expression, one argument must be provided before
-the expression can be evaluated. In the second, two arguments are needed. We
-could say the /arity/ of the first expression is one and of the second is two.
-The arity is determined by the highest placeholder in the expression. Our job
-will be to write a transform that calculates the arity of any calculator
-expression.
-
-[note *Why Bother Calculating Expression Arity?*
-
-This is more than just an intelectual exercise. Knowing the arity of a calculator
-expression is important if you want to give users a meaningful error message when
-they specify too few or too many arguments to an expression.]
-
-[/=========================]
-[heading Defining a Grammar]
-[/=========================]
-
-First, we must write the grammar for the calculator. It's really very simple.
-Calculator expression can be made up of any combination of 5 constituents:
-
-* Placeholder 1
-* Placeholder 2
-* A literal
-* Unary operations
-* Binary operations
-
-We can immediately write the calculator grammar as follows:
-
-[CalcGrammar]
-
-We can read this as follows: a calculator expression is either placeholder 1,
-placeholder 2, some other terminal, or some unary or binary operator whose operands
-are calculator expressions. Recall that `proto::_` is a wildcard that matches
-anything. So `proto::terminal< _ >` will match any terminal, and
-`proto::unary_expr< _, CalcArity >` will match any unary expression for which the
-operand matches `CalcArity` (the `_` matches any operator tag).
-
-[/============================]
-[heading Writing the Transform]
-[/============================]
-
-It's straightforward to describe in words how the arity of an expression should
-be calculated. First, we describe the arity of each of the 5 constituents in
-the calculator grammar.
-
-[table Calculator Sub-Expression Arities
- [[Sub-Expression] [Arity]]
- [[Placeholder 1] [`1`]]
- [[Placeholder 2] [`2`]]
- [[Literal] [`0`]]
- [[Unary Expression] [ /arity of the operand/ ]]
- [[Binary Expression] [ /max arity of the two operands/ ]]
-]
-
-The total arity of a calculator expression is found by recursively evaluating
-the arity of all of the sub-expressions and taking the maximum.
-
-Let's look at the sub-expression for the placeholder `_1`. It is matched by this
-part of our grammar: `proto::terminal< placeholder<0> >`. We want to associate this
-part of our grammar with an arity of `1`. We do that by attaching a transform.
-Since the arity of an expression can be evaluated at compile time, let's use
-`mpl::int_<1>` to represent the arity of the first placeholder. The following
-attaches a transform that always evaluates to `mpl::int_<1>`:
-
- proto::when< proto::terminal< placeholder<0> >, mpl::int_<1>() >
-
-This grammar rule will match any `placeholder<0>` terminal, and will transform it
-to a (default-constructed) `mpl::int_<1>` object. As described previously,
-`mpl::int_<1>()` is a function type, but Proto interprets it as an object to
-construct. We will have a similar transform to convert `placeholder<1>` terminals
-into `mpl::int_<2>`, and other terminals into `mpl::int_<0>`.
-
-Next, let's write a transform for unary operators that returns the arity of the
-operand. It is simply:
-
- proto::when< proto::unary_expr< _, CalcArity >, CalcArity(proto::_child) >
-
-The transform `CalcArity(proto::_child)` recursively applies the `CalcArity`
-transform to the child node of the unary expression. As you might have noticed,
-`CalcArity(proto::_child)` is another function type, but Proto interprets this one
-differently. Rather than trying to construct a `CalcArity` object, Proto
-knows this is a function object and invokes it instead.
-
-[/================================================]
-[note *Object Transforms vs. Callable Transforms*
-
-When using function types as Proto transforms, they can either represent an object
-to construct or a function to call. It is similar to C++ where the syntax `foo(x)`
-can either be interpreted as an object to construct or a function to call,
-depending on whether `foo` is a type or a function. Proto can't know in general
-which is the case, so it uses a trait, `proto::is_callable<>`, to differentiate.
-`is_callable< mpl::int_<1> >::value` is false so `mpl::int_<1>()` is an object to
-construct, but `is_callable< CalcArity >::value` is true so
-`CalcArity(proto::_child)` is a function to call.
-(`is_callable< CalcArity >::value` is true because `CalcArity` inherits from
-`proto::or_<>`, which is callable.)]
-[/================================================]
-
-[/
- That begs the question, what does `unary_expr<>`'s transform do? Well,
- `unary_expr< _, CalcArity >` has a default transform
- associated with it. It is a /pass-through/ transform. When an expression
- of the form `expr< T, list1< X > >` is passed to the transform, its `apply<>`
- member template will invoke the `CalcArity` transform (which we haven't
- completely defined yet -- patience) on `X` resulting in `Y`, and then
- reassemble the expression as `expr< T, list1< Y > >`.
-
- [note You may have noticed that Proto types like `unary_expr<>` serve several
- different but related roles. In particular, `unary_expr<>` is ...
-
- ... [*a metafunction]: `unary_expr<T, X>::type` is a typedef for
- `expr<T, list1<X> >`.
-
- ... [*a grammar]: `unary_expr<U, Y>` is a simle grammar that matches
- `expr<T, list1<X> >` if an only if `U` is `T` or `proto::_`, and `Y` is a
- grammar that matches `X`.
-
- ... [*a transform]: `unary_expr<U, Y>::apply<expr<T, list1<X> >, S, V>::type`
- applies `unary_expr<>`'s pass-through transform to `expr<T, list1<X> >` with
- state `S` and data `V`. The result is
- `expr<T, list1< Y::apply<X, S, V>::type > >`.
- ]
-
- So, putting a few things together, consider the calculator expression `+_1`,
- which would have the following type:
-
- expr< tag::unary_plus, list1<
- expr< tag::terminal, term< placeholder<0> > >
- > >
-
- If we executed the `unary_expr< _, CalcArity >` transform on this
- expression, we would expect to get:
-
- expr< tag::unary_plus, list1<
- mpl::int_<1>
- > >
-
- And if we added the `_child<>` transform also, as in
- `child< unary_expr< _, CalcArity > >`, we expect the result
- to be:
-
- mpl::int_<1>
-
- Which is exactly what we want.
-
- [note *Default Transforms*
-
- All the tools Proto provides for defining grammar rules have default transforms
- associated with them. Just as `unary_expr<>` has a pass-through transform,
- so too does `binary_expr<>`, `shift_right<>`, and all the others.
- `proto::or_<>` has a default transform which evaluates the transform of the
- branch that matched. `proto::and_<>`'s default transform evaluates the
- transform of the last branch. Even `proto::expr<>`, `proto::if_<>`,
- `proto::not_<>`, and `proto::_` have no-op default transforms that simply return
- unmodified the expressions passed to them.
- ]
-]
-
-The arity of a binary operator is the maximum of the arity of the left and
-right operands. We can specify this with the help of `mpl::max<>`, which is a
-so-called metafunction that computes the maximum of two compile-time integers.
-The transform is described below:
-
- proto::when< proto::binary_expr< _, CalcArity, CalcArity >,
- mpl::max< CalcArity(proto::_left), CalcArity(proto::_right) >()
- >
-
-The above says to match binary calculator expressions and compute their
-arity by first computing the arity of the left and right children and then
-taking their maximum.
-
-[def _X_ [~X]]
-[def _Y_ [~Y]]
-[def _Z_ [~Z]]
-
-There's a lot going on in the above transform, so let's take it one piece
-at a time, starting with the parts we know. `CalcArity(proto::_left)`
-will calculate the arity of the left child, returning a compile-time integer.
-Likewise for `CalcArity(proto::_right)`. What is new is that these two
-transforms are nested within another: `mpl::max<...>()`. Proto notices that
-`mpl::max<...>` is not callable, so this transform is interpreted as an
-object to construct rather than a function to invoke. Using meta-programming
-tricks, Proto disassembles the `mpl::max<...>` template looking for nested
-Proto transforms to apply. It finds two and applies them, resulting in
-`mpl::max< mpl::int_<_X_>, mpl::int_<_Y_> >`.
-
-Having first applied any nested transforms, Proto then looks to see if
-`mpl::max< mpl::int_<_X_>, mpl::int_<_Y_> >` has a nested `::type` typedef.
-This is a common convention used by metafunctions. In this case,
-`mpl::max<...>::type` is a typedef for `mpl::int_< _Z_ >` where `_Z_` is the
-maximum of `_X_` and `_Y_`. The trailing `()` on the transform indicates that
-the result should be default-constructed, so this transform returns
-`mpl::int_<_Z_>()`. And we're done.
-
-[note Had `mpl::max<>` not had a nested `::type` typedef, the transform
-would have created and returned a default-constructed `mpl::max<>` object
-instead. That is, the result of substituting nested transforms need not
-of necessity have a nested `::type` typedef, but it is used if it is there.]
-
-Piecing it all together, the complete `CalcArity` looks like this:
-
-[CalcArity]
-
-We can use our `CalcArity` transform to calculate the arity of any
-calculator expression:
-
- CalcArity arity_of;
- std::cout << arity_of( proto::lit(100) * 20 ) << '\n';
- std::cout << arity_of( (_1 - _1) / _1 * 100 ) << '\n';
- std::cout << arity_of( (_2 - _1) / _2 * 100 ) << '\n';
-
-This displays the following:
-
-[pre
-0
-1
-2
-]
-
-(Aside: the output statements use the fact that `mpl::int_<_X_>`
-has a conversion to `int(_X_)`.)
-
-[endsect]
-
-[/========================]
-[section Canned Transforms]
-[/========================]
-
-So far, we've seen how to write custom transforms using function types.
-These were implemented in terms of more primitive transforms provided by
-Proto, such as `_child`, `_left`, and `_right`. This section describes those
-transforms and others in detail.
-
-[/
-
-Why is this here??
-
-All the transforms defined in this section are of the following form:
-
-[def _some_transform_ [~some_transform]]
-
- struct _some_transform_ : proto::transform< _some_transform_ >
- {
- template<typename Expr, typename State, typename Date>
- struct impl : proto::transform_impl< Expr, State, Data >
- {
- typedef ... result_type;
-
- result_type operator()(
- typename impl::expr_param expr
- , typename impl::state_param state
- , typename impl::data_param data
- ) const
- {
- return ...;
- }
- };
- };
-
-So defined, `_some_transform_` is a transform "in the raw", just like
-`proto::_value` or `proto::_child`. These transforms are the building
-blocks from which you can compose larger transforms using function types.
-
-]
-
-[section:child_c_and_friends [^_value], [^_child], [^_left], and [^_right]]
-
- namespace boost { namespace proto
- {
- struct _value;
-
- template<long N>
- struct _child_c;
-
- typedef _child_c<0> _child0;
- typedef _child_c<1> _child1;
- // ... up to BOOST_PROTO_MAX_ARITY-1
-
- typedef _child_c<0> _child;
- typedef _child_c<0> _left;
- typedef _child_c<1> _right;
- }}
-
-These transforms are useful for extracting the ['[^N]]th argument from an
-expression. The `_left` transform is equivalent to the `_child_c<0>` transform,
-and the `_right` transform is equivalent to the `_child_c<1>` transform. The
-`_value` transform extracts the value from a terminal expression.

-The target of a callable transform can be any function object that implements
-the Boost.ResultOf protocol. Function objects that take up to
-`BOOST_PROTO_MAX_ARITY` are handled.
-
-For callable transforms that take 0, 1, or 2 arguments, special handling is done
-to see if the transform actually expects 3 arguments, as Proto's primitive
-transforms do. (This can be detected with meta-programming tricks.) So, even
-though a transform like `_child1` requires three parameters: expression,
-state and data; it can be "called" with just one, like `_child1(_child2)`. Proto
-treats this as if were `call<_child1(_child2, _state, _data)>`.
-
-If no transform arguments are specified at all, as in `call<_child1>`, this is
-the same as `_child1`. For this reason, `call<_child1>(_child2)` is the same as
-`call<_child1(_child2)>`.
-

-The `make<>` transform is used to construct objects and evaluate

-]
-
-You might decide to use `make<>` to explicitly differentiate object
-transforms from callable transforms. (See `call<>`.)
-
-[tip For users of legacy compilers like MSVC 7.1, `make<>` is useful to work
-around compiler bugs. Doubly-nested transforms such as `Object1(Object2(_child))`
-cause older compilers problems, but the equivalent `Object1(make<Object2(_child)>)`
-solves the problem.]
-
-The `make<>` transform checks to see if the resulting object type is a template.
-If it is, the template type is disassembled to find nested transforms. Proto
-considers the following types to represent transforms:
-
-[def __type__ [~type]]
-[def __X__ X\']
-[def __X0__ X0\']
-[def __X1__ X1\']
-[def __MakeImpl__ [~[^MakeImpl]]]
-
-* Function types
-* Function pointer types
-* Types for which `proto::is_callable<__type__>::value` is `true`
-
-When an object transform with a template type such as
-`Object<X0,X1,...>(Args...)` is evaluated with a given
-`Expr`, `State`, and `Data`, the result type is
-`__MakeImpl__<Object<X0,X1,...>, Expr, State, Data>::type` which is
-defined as follows. For each `X` in `X0,X1,...`, do:
-
-* If `X` is a transform, then let `__X__` be
- `boost::result_of<proto::when<_, X>(Expr, State, Data)>::type`.
- Note that a substitution took place.
-* Otherwise, if `X` is a template like `Object2<Y0,Y1,...>`, then
- let `__X__` be `__MakeImpl__<Object2<Y0,Y1,...>, Expr, State, Data>::type`
- (which evaluates this procedure recursively). Note whether any
- substitutions took place during this operation.
-* Otherwise, let `__X__` be `X`, and note that no substitution
- took place.
-* If any substitutions took place in any of the above steps and
- `Object<__X0__,__X1__,...>` has a nested `::type` typedef, the
- result type is `Object<__X0__,__X1__,...>::type`.
-* Otherwise, the result type is `Object<__X0__,__X1__,...>`.
-
-Note that `when<>` is implemented in terms of `call<>` and `make<>`,
-so the above procedure is evaluated recursively.

-
-Objects with constructors that take up to `BOOST_PROTO_MAX_ARITY` are handled.
-Some types are so-called /aggregates/ that do not have constructors; rather,
-they use /aggregate initialization/. For these types, you can specialize
-`proto::is_aggregate<>` and Proto will use a brace initializer list to
-initialize the object rather than a constructor. Proto knows that `proto::expr<>`
-is such an aggregate, so if you use object transforms to "construct" a
-new node in an expression tree, the right thing happens.
-
-If no transform arguments are specified at all, as in `make<Object>`, this is
-the same as `make<Object()>`.

-Sometimes you would like a higher-order transform that returns another

-whose behavior needs to be parameterized on the current state of the
-transformation. For these situations, you can use the `lazy<>` transform,

-any nested transforms and create the higher-order transform) followed
-by an invocation of `call<>` (to actually execute the higher-order

-The transforms `fold<>` and `reverse_fold<>` are akin to the
-`std::accumulate()` algorithm in the STL, or the `fold()` algorithm in
-Boost.Fusion. They iterate over some sequence and
-accumulate some state at each element. The `fold<>`
-transform iterates over the children in order, starting with the 0th child.
-The `reverse_fold<>` transform does it in reverse order, starting with the Nth
-child. (Note that for building things like cons lists, you'll often want to
-built it back-to-front with `reverse_fold<>`.)
-
-Both `fold<>` and `reverse_fold<>` are implemented in terms of `fusion::fold<>`.
-The three template parameters must each be Proto transforms. The have the following
-meaning:
-
-* `Sequence`: A Proto transform that returns a Fusion sequence.
-* `State`: A Proto transform that returns the initial state of the fold.
-* `Fun`: A Proto transform representing the operation to perform at each
- iteration of the fold algorithm.
-
-Often, the `Sequence` parameter is `proto::_`, which returns the current node
-in the Proto expression tree. Tree nodes are valid Fusion sequences, where
-the children are the elements of the sequence.
-

-The semantics of the `fold<>` and `reverse_fold<>` transforms can both be

-The `fold_tree<>` and `reverse_fold_tree<>` transforms recursively apply the

-into a Fusion list like `cons(a, cons(b, cons(c)))`.

-composing transforms using function types problematic. Finally,
-you might also decide to define your own primitive transforms
-to improve compile times. Since Proto can simply invoke a
-primitive transform directly without having to process arguments
-or differentiate callable transforms from object transforms,
-primitive transforms are more efficient.]
-
-[def _N_ [~N]]
-
-Primitive transforms inherit from `proto::transform<>`
-and have a nested `impl<>` template that inherits from
-`proto::transform_impl<>`. For example, this is how Proto
-defines the `_child_c<_N_>` transform, which returns the
-_N_-th child of the current expression:
-
- namespace boost { namespace proto
- {
- // A primitive transform that returns N-th child
- // of the current expression.
- template<int N>
- struct _child_c : transform<_child_c<N> >
- {
- template<typename Expr, typename State, typename Data>
- struct impl : transform_impl<Expr, State, Data>
- {
- typedef
- typename result_of::child_c<Expr, N>::type
- result_type;
-
- result_type operator ()(
- typename impl::expr_param expr
- , typename impl::state_param state
- , typename impl::data_param data
- ) const
- {
- return proto::child_c<N>(expr);
- }
- };
- };
-
- // Note that _child_c<N> is callable, so that
- // it can be used with arguments, as:
- // _child_c<0>(_child_c<1>)
- template<int N>
- struct is_callable<_child_c<N> >
- : mpl::true_
- {};
- }}
-
-The `proto::transform<>` base class provides the `operator()` overloads
-and the nested `result<>` template that make your transform a valid
-function object. These are implemented in terms of the nested `impl<>`
-template you define.
-
-The `proto::transform_impl<>` base class is a convenience. It
-provides some nested typedefs that are generally useful. The are
-specified in the table below:
-
-[table proto::transform_impl<Expr, State, Data> typedefs
-[[typedef][Equivalent To]]
-[[`expr`][`typename remove_reference<Expr>::type`]]
-[[`state`][`typename remove_reference<State>::type`]]
-[[`data`][`typename remove_reference<Data>::type`]]
-[[`expr_param`][`typename add_reference<typename add_const<Expr>::type>::type`]]
-[[`state_param`][`typename add_reference<typename add_const<State>::type>::type`]]
-[[`data_param`][`typename add_reference<typename add_const<Data>::type>::type`]]
-]
-
-You'll notice that `_child_c::impl::operator()` takes arguments of types
-`expr_param`, `state_param`, and `data_param`. The typedefs make it easy to
-accept arguments by reference or const reference accordingly.
-
-The only other interesting bit is the `is_callable<>` specialization, which
-will be described in the
-[link boost_proto.users_guide.expression_transformation.is_callable
-next section].

-[section:is_callable Making Your Transform Callable]
-[/=================================================]
-
-Transforms are typically of the form `proto::when< Something, R(A0,A1,...) >`. The
-question is whether `R` represents a function to call or an object to
-construct, and the answer determines how _when_ evaluates the transform.
-_when_ uses the `proto::is_callable<>` trait to disambiguate between the two.
-Proto does its best to guess whether a transform is callable or not, but
-it doesn't always get it right. It's best to know the rules Proto uses,
-so that you know when you need to be more explicit.
-
-For most types `T`, `proto::is_callable<T>` checks for inheritence from
-`proto::callable`. However, if the type `T` is a template specialization,
-Proto assumes that it is /not/ callable ['even if the template inherits from
-`proto::callable`]. We'll see why in a minute. Consider the following erroneous
-callable transform:
-
- // Proto can't tell this defines a
- // callable transform!
- template<typename T>
- struct times2 : proto::callable
- {
- typedef T result_type;
-
- T operator()(T i) const
- {
- return i * 2;
- }
- };
-
- // ERROR! This is not going to
- // multiply the int by 2.
- struct IntTimes2
- : proto::when<
- proto::terminal<int>
- , times2<int>(proto::_value)
- >
- {};
-
-The problem is that Proto doesn't know that `times2<int>` is a callable
-transform. Instead, it assumes it is an object transform and will try to
-construct a `times2<int>` object and initialize it will an `int`. That
-will not compile.
-
-[note Why can't Proto tell that `times2<int>` is callable? After all,
-it inherits from `proto::callable`, and that is detectable, right?
-The problem is that merely asking whether some type `X<Y>` inherits from
-`callable` will cause the template `X<Y>` to be instantiated. That's a
-problem for a type like `std::vector<_value(_child1)>`. `std::vector<>`
-will not suffer to be instantiated with `_value(_child1)` as a template
-parameter. As a result, Proto has to assume that a type `X<Y>` represents
-an object transform and not a callable transform.]
-
-There are a couple of solutions to the `times2<int>` problem. One
-solution is to wrap the transform in `proto::call<>`. This forces Proto
-to treat `times2<int>` as callable:
-
- // OK, calls times2<int>
- struct IntTimes2
- : proto::when<
- proto::terminal<int>
- , proto::call<times2<int>(proto::_value)>
- >
- {};
-
-This can be a bit of a pain, because we need to wrap every use of
-`times2<int>`, which can be tedious and error prone, and makes our
-grammar cluttered and harder to read.
-
-Another solution is to specialize `proto::is_callable<>` on our
-`times2<>` template:
-
- namespace boost { namespace proto
- {
- template<typename T>
- struct is_callable<times2<T> >
- : mpl::true_
- {};
- }}
-
- // OK, times2<> is callable
- struct IntTimes2
- : proto::when<
- proto::terminal<int>
- , times2<int>(proto::_value)
- >
- {};
-
-This is better, but still a pain because of the need to open
-Proto's namespace.
-
-You could simply make sure that the transform is not
-a template specialization. Consider the following:
-
- // No longer a template specialization!
- struct times2int : times2<int> {};
-
- // OK, times2int is callable
- struct IntTimes2
- : proto::when<
- proto::terminal<int>
- , times2int(proto::_value)
- >
- {};
-
-This works because now Proto can tell that `times2int` inherits
-(indirectly) from `proto::callable`. Any non-template types can
-be safely checked for inheritance because, as they are not
-templates, there is no worry about instantiation errors.
-
-There is one last way to tell Proto that `times2<>` is callable.
-You could add an extra dummy template parameter that defaults
-to `proto::callable`:
-
- // Proto will recognize this as callable
- template<typename T, typename Callable = proto::callable>
- struct times2 : proto::callable
- {
- typedef T result_type;
-
- T operator()(T i) const
- {
- return i * 2;
- }
- };
-
- // OK, this works!
- struct IntTimes2
- : proto::when<
- proto::terminal<int>
- , times2<int>(proto::_value)
- >
- {};
-
-Note that in addition to the extra template parameter, `times2<>`
-still inherits from `proto::callable`. That's not necessary in this
-example but it's good style because any types derived from `times2<>`
-(as `times2int` defined above) will still be considered callable.
