[proto] Understanding arg
by David A. Greene 14 Jul '07

14 Jul '07

Eric, Several newbie questions here. I'm trying to understand how the proto::arg transform works. Looking at the Mixed example, I see this: template<typename Grammar> struct begin : Grammar { template<typename Expr, typename State, typename Visitor> struct apply : proto::terminal< iterator_wrapper< typename proto::result_of::arg<Expr>::type::const_iterator > > {}; template<typename Expr, typename State, typename Visitor> static typename apply<Expr, State, Visitor>::type call(Expr const &expr, State const &state, Visitor &visitor) { return proto::as_expr(cbegin(proto::arg(expr))); } }; Not knowing exactly what cbegin does, I think this makes sense to me. Given a grammar like this: // Here is the grammar for if_ statements // matches if_(e1)[e2] struct IfGrammar : boost::proto::subscript< boost::proto::unary_expr< tag::If, ExpressionGrammar >, StatementGrammar > {}; I want to create an AST node representing the statement. So I wrote a custom transform like this: // Transform a two-operand node template<typename Grammar, typename NodeType> struct ConstructBinaryLeftNested { : Grammar { template<typename Expr, typename State, typename Visitor> struct apply { typedef typename Ptr<NodeType>::type type; }; template<typename Expr, typename State, typename Visitor> static typename apply<Expr, State, Visitor>::type call(Expr const &expr, State const &state, Visitor &visitor) { return(new typename apply<Expr, State, Visitor>::type( Grammar::call(proto::arg(proto::left(expr)),state,visitor), Grammar::call(proto::right(expr),state,visitor))); } } } And use it like this: struct StatementGrammar : boost::proto::or< ConstructBinaryLeftNested<IfGrammar, IfStatement>, ... Essentially, I want to generate code like this: new IfStatement( transformed arg of unary_expr, // The condition transformed arg of subscript); // The statement block So several questions arise: - Is this use of arg/left allowed and correct? - If not, do I have to use identity instead to pass up the grandchild? - If not, what should I do? Something's telling me I'm not understanding something really fundamental. In particular, I don't understand the use of arg in the run-time code of Mixed vs. the use of arg as a compile-time transform. Some annotated examples of how proto transforms work with runtime code would be helpful. The calc transform examples are all pure compile-time code. Also, how do I get the arity of an expression at compile time? I need to be able to construct an AST node representing a function call which could have any number of arguments: struct CallGrammar : boost::proto::function<ExpressionGrammar, boost::proto::vararg<ExpressionGrammar> > {}; I need a transform that looks something like this: // Transform an n-ary node template<typename Grammar, typename NodeType> struct ConstructNary { : Grammar { template<typename Expr, typename State, typename Visitor> struct apply { typedef typename Ptr<NodeType>::type type; }; template<typename Expr, typename State, typename Visitor> static typename apply<Expr, State, Visitor>::type call(Expr const &expr, State const &state, Visitor &visitor) { func = new typename apply<Expr, State, Visitor>::type( // Function name Grammar::call(proto::arg<0>(expr),state,visitor)); // Generate func->addArgument(arg<i>(expr)) for each child ct_for<numargs(expr)-1>::exec(expr, func); return(func); } } } Does this make sense? Is it possible? Thanks for your help. -Dave

Boost Inspection Report Run Date: 16:11:59 UTC, Saturday 14 July 2007 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11452 files scanned 909 directories scanned (including root) 162 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 3 invalid urls 70

Interest in tensor library?
by Jeremy Bruestle 14 Jul '07

14 Jul '07

Greetings, I have developed a C++ tensor library using template expressions which allows Einstein summation convention to be used to describe mathematical operations on tensors in C++. This allows a great simplification in syntax, while retaining execution speeds identical to hand optimized C code in most cases. An example of the syntax is: // Declare three rank 2 tensors (rank = # of dimensions) of doubles with sizes of // 6 x 5, 6 x 10, and 10 x 5 respectively tensor<double, 2> A(6, 5); tensor<double, 2> B(6, 10); tensor<double, 2> C(10, 5); // Name three index variable to be used in what follows index_variable<0> i; index_variable<1> j; index_variable<2> k; A[i][j] = 1.0; // Initialize A to all 1's B[i][j] = 4.5; // Initalize B to all 4.5 boost::mt19937 rng; C[i][j] = trand(rng); // Initalize C to uniform random numbers 0-1 C[i][2] = 2.1; // Set row 2 to 2.1 C[2][i] = 5.5; // Set col 2 to 5.5 C[2][2] = 0.0; // Zero out 2,2 A[i][j] = B[i][k] * C[k][j]; // Perform a matrix multiply /* The above line translates roughly as: for(size_t i = 0; i < A.size<0>(); i++) { for(size_t j = 0; j < A.size<1>(); j++) { double total = 0.0; for(size_t k = 0; k < B.size<1>(); k++) total += B[i][k] * C[k][j]; A[i][j] = total; } } */ An unlimited number of dimensions are supported, arbitrary operations are allowed, and for cases where you wish to perform other types of cumulative functions, such as finding the maximum element, a syntax such as: A[i] = max(j, B[i][j]); is allowed. There are lots of other interesting features but I don't wish to make this email too long. As far as efficency, Intel's compiler builds every example I've tried so far into code as good as doing the work by hand. GCC does so for expressions of reasonably complexity, and MSVC's optimizer does alright, but not nearly as well as the others. I was interested in knowing what the interest level of providing such a library as part of boost would be. I've tried to adhere to the boost coding guidelines during the construction. I've been using this library for over 6 months myself for scientific computing. However, I've so far avoiding sending a query to the boost mailing lists as the procedures for submission and review seem quite daunting. I'm usually crushingly busy, and I'm also especially bad at documentation. Still, I thought I would float the idea to guage interest, and also ask if anyone would be interested in helping me through the process somewhat. Thank you for you time. -Jeremy Bruestle

[IBD] Helping Boost Authors
by Matias Capeletto 14 Jul '07

14 Jul '07

Hello Boosters, We have a new resource at IBD: a section in the project Wiki called "Helping Boost Authors". http://svn.boost.org/trac/boost/wiki/HelpingBoostAuthors This section is a bazaar of friendly hands. We are teachers, experience users, native English speakers and artists. We want to offer our help to Boost authors to improve their documentation. * How to get helped Just send an email to the boost-docs list with your request. We will do our best to help you. * How to help Add yourself as a proofreader, a translator or in the general section if you have others ideas that Boost authors may find useful. The main objective of this new resource is to act as the main connection between Boost authors and some of IBD folks that are eager to help them. We hope this will make healthier the relation between Boost authors and our project. Authors will get helped, and have more time to improve and add new features to their libraries. We will get in touch with you and hopefully learn enough to become a boost author someday. It is a win-win situation. We hope we can make Boost authors life more enjoyable with regards to documentation. Eagerly waiting to help somebody, King regards Matias
