url encoding
by Kraus Philipp 25 Jul '11

Hello, does boost support any url encoding structures? I would like to transform a std::string with spaces and other chars to the correct url representation (space will be changed to %20 ...). Thanks Phil

Dear advanced boost/c/g++ programers: I copied and try a simple (Reading a directory with boost) program , from page 383, Example 10-19, of book(C++ cookbook) ----------you can download the code to try by yourself at, http://examples.oreilly.com/9780596007614/ // Example 10-19.

Boost.Iterator questions
by John M. Dlugosz 24 Jul '11

24 Jul '11

Consider something similar to what Glib::ustring does, only better made. If I have a sequence of characters (say, in a normal std::string) and want to use an adaptor to decode UTF-8 code points, the resulting adapted iterator returns a different type (element is char32_t), not an lvalue, and consumes a variable number of underlying elements. It's not just a transform_iterator because it consumes a variable number of underlying elements. It's not writable because a new value might encode a different number of underlying elements than the one it is replacing. I think I need to implement it directly from iterator_facade, not one of the more specialized classes already provided. Am I mistaken? What is the traversal type? Random access is _possible_ just not efficient. To move forward n locations it has to increment n times. ++ and −− are fine. There is indeed a well defined distance between two iterators, but I don't want to encourage that kind of thing and hide the inefficiency. But, I see that relational operators are defined for random access (only), not for bidirectional? Why is that? Note that relational operators for the proposed type _are_ efficient, as it can defer to the underlying iterator. I knows which is greater, just not by how much exactly. The template argument for Difference, in the tutorial, mentions "distance between any two addresses in memory". But the distance between two locations is not the same as the difference in bytes. Is this being implied? After all, the example is a linked list and the distance from one node to another, in hops, has no relation to the address at all. Is Difference something I need to worry about?

[iterator] iterator_core_access and namespaces
by Nathan Ridge 24 Jul '11

24 Jul '11

Hello, I came across what seems like an interesting oddity: #include <boost/iterator/iterator_facade.hpp> using boost::iterator_core_access; namespace ns { struct range { class iterator : public boost::iterator_facade<iterator, int, boost::single_pass_traversal_tag> { friend class iterator_core_access; int& dereference() const; void increment(); bool equal(const iterator& other) const; }; typedef iterator iterator; iterator begin(); iterator end(); }; } int main() { ns::range::iterator b; ++b; } This code goes not compile with gcc (I tried with 4.3 through 4.7), giving the following error: test.cpp: In static member function 'static void boost::iterator_core_access::increment(Facade&) [with Facade = ns::range::iterator]': boost/boost/iterator/iterator_facade.hpp:664:11: instantiated from 'Derived& boost::iterator_facade<I, V, TC, R, D>::operator++() [with Derived = ns::range::iterator, Value = int, CategoryOrTraversal = boost::single_pass_traversal_tag, Reference = int&, Difference = int]' test.cpp:29:7: instantiated from here test.cpp:16:18: error: 'void ns::range::iterator::increment()' is private boost/boost/iterator/iterator_facade.hpp:523:11: error: within this context If I explicitly qualify iterator_core_access in the friend declaration (i.e. "friend class boost::iterator_core_access"), or if I move the "using boost::iterator_core_access" inside the namespace, it works fine. Is this a compiler bug, or am I bumping into a shadowy corner of the Standard involving friends and namespaces? Thanks, Nate.

Trying to use Boost::thread
by Allan Nielsen 23 Jul '11

Hi, I am trying to use boost::thread to copy data from one stream to another. For this I have written the following code, but can can not compile it and I do not under stand why... Is there an better way to do this? -- Allan #include <fstream> #include <iostream> #include "Poco/Net/HTTPClientSession.h" #include "Poco/Net/HTTPRequest.h" #include "Poco/Net/HTTPResponse.h" #include "Poco/StreamCopier.h" #include "Poco/Path.h" #include "Poco/URI.h" #include <boost/thread.hpp> using namespace std; using namespace Poco; using namespace Poco::Net; struct Test { Test (const std::string & s_url) : uri(s_url), path(uri.getPathAndQuery()), session(uri.getHost(), uri.getPort()) { if (path.empty()) path = "/"; HTTPRequest req(HTTPRequest::HTTP_GET, path, HTTPMessage::HTTP_1_1); session.sendRequest(req); // Compiler error // boost::thread(boost::ref(*this)); // this compiles boost::packaged_task<int> pt(boost::ref(*this)); boost::unique_future<int> fi=pt.get_future(); boost::thread task(boost::move(pt)); } int operator()() { ofstream null("/dev/null"); std::istream& rs = session.receiveResponse(res); StreamCopier::copyStream(rs, null); } URI uri; std::string path; HTTPClientSession session; HTTPResponse res; }; int main(int argc, const char *argv[]) { Test test("http://localhost/gmbfs"); // TODO, sync return 0; }

Use Boost thread and store results of function into object's local variable.
by Damian 23 Jul '11

23 Jul '11

Hello. I'm a new to Boost and the listserv so please forgive my ignorance if my question is obvious. I have found the Boost documentation and example difficult to use for my needs (perhaps I'm just not using the correct packages). I have a vector of objects each of which needs to do so calculations. Each vector element can run independently and doesn't rely on anything other than its own private variables. I'd like to launch N threads (where N can vary from 1...8 let's say) and pass to each thread 1 element of the vector. Within the threads, each object crunches its numbers and stores its result in its local variable. I've got some code here but it won't compile. I get this error message: "cannot call member function ‘void PSMClass::process()’ without object" I think the problem is that I'm not passing the vector element itself but rather a pointer to it (?). Perhaps this isn't the best approach, I don't know. Can anyone help me out? Thanks in advance for any and all help. ################################################################ #include <iostream> #include <vector> #include <cstdlib> #include <boost/thread.hpp> #include <boost/bind.hpp> using namespace std; class PSMClass; class PSMClass { private: int id; double x; double y; public: PSMClass(){}; // default ctor PSMClass(int i, double a); // constructor void process(); int getId() { return id; } double getX(){ return x; } double getY(){ return y; } void innerFunc(double r); }; PSMClass::PSMClass(int i, double a) { id = i; x = a; y = 0; } // just some function that we want to run in parallel void PSMClass::process() { double r = 0; double odd = 0; int STOP = id * 10000000; for(int i = 0; i < STOP; i++) { r += 1; // this is just some random code I through in to make the process // CPU-intensive yet slow enough for me to monitor it on 'top' odd = (double)rand() * sin( (double)rand() ); } innerFunc(r); odd = 0; } // just another function to obfuscate matters void PSMClass::innerFunc(double r) { y = r; } /******************************************************************************* * * Main Function * ******************************************************************************/ int main(int argc, char* argv[]) { PSMClass *curPSM = NULL; vector<PSMClass> PSM_vec; vector<PSMClass>::iterator v; double r; int N = 10; for(int i = 0; i < N; i++) { r = (double) (rand() % N + 1000); curPSM = new PSMClass(i, r); PSM_vec.push_back(*curPSM); delete(curPSM); curPSM = NULL; } cout << "Initial states:\n"; cout << "id\tx\ty\n"; for(v = PSM_vec.begin(); v != PSM_vec.end(); v++) { cout << v->getId() << "\t" << v->getX() << "\t" << v->getY() << endl; } cout << endl; // we want to limit TG to just 2 threads.

[rational] proposed gcd and lcm for rational
by Thomas Taylor 22 Jul '11

22 Jul '11

Dear boost users and maintainers, As I needed these functions myself I have added a gcd and an lcm for the rational type. Feel free to do with the code whatever you want, if suitable add it to rational.hpp. Presumably this could be reworked as partial specialisation of boost::math::gcd and boost::math::lcm respectively (if there is a trait like is_rational). HTH, Thomas
