i’d same stuff can d’s mixins c/c++ preprocessor. i’d write function generate parameter list. instance: #define mk_fn_foo(n,t) … mk_fn_foo(3,float) /* expand */ void foo(float x0, float x1, float x2) { /* else here */ } i have idea i’m facing issue. have recursion , have no idea how such thing: #define mk_foo(n,t) void foo(mk_foo_plist(n-1,t)) { } #define mk_foo_plist(n,t) t xn, mk_foo_plist(n-1,t) /* how stop that?! */ the boost libraries have vast extensive metaprogramming , else preprocessor library. possible kind of thing using utility preprocessor directives easier doing yourself, although still confusing :) i suggest start there: http://www.boost.org/doc/libs/1_53_0/libs/preprocessor/doc/index.html http://www.boost.org/doc/libs/?view=category_preprocessor edit: here tutorial them: boost.preprocessor - tutorial

like title says, i'd able perform different onstatechange event if pushstate function called, instead of back function. or, if go function negative or positive. example: if history.pushstate() or history.go(1) called, want statechange event's callback forwardpushstate if history.back() or history.go(-1) called, want statechange event's callback backwardspushstate a state data related page (as user see in browser). if user wants in page, page same, either if coming button click or forward button click, think. pushstate pushes new state in stack. has no relationship back , go . back , go functions navigate on pushed states in stack. because in edit, looks thinking pushstate , go(1) equivalent. maybe if want know direction user coming, should analyse onstatechange event know if takes parameter stores direction. still don't know how do. the main thing think, has no relationship go (-1) or go(1) or back .
