i got official answer this question decltype should not trigger function compilation. in fact decltype on function declared not defined legal. next question, should taking address of function trigger compilation of function? take this example : template <typename t> void foo(t&& x) { x.func(); } int main() { auto bar = &foo<int>; } all compilers i've tested fail error like: request member func in x , of non-class type int but if define foo , don't declare it, code compiles fine. can provide me official source on whether taking address of function should require it's compilation? 3.2/2: an expression potentially evaluated unless unevaluated operand (clause 5) or subexpression thereof. ... non-overloaded function name appears potentially-evaluated expression or member of set of candidate functions, if selected overload resolution when referred potentially-evaluated expression, odr-used, unless pure ...

i have created span tags dynamically , appended div. want id, 1 select , delete it. jquery tagit. below using not working. see id can when click particular span. $('span').on('click', function (e){ alert(e.target.id); }); you don't need id (and span may not have one), have reference element: this . that's standard jquery behavior. (in fact, it's standard across various ways can hook events without jquery too.) so $('span').on('click', function() { $(this).remove(); // removes 1 clicked }); (or, yes, add e , use e.target : $(e.target).remove(); ) re comment: i tried using code giving alert click event not firing. that suggests span s in question don't exist of when code runs, , don't end hooking click event. to deal that, want delegated handler: in dev tools, right-click 1 of these spans , find common ancestor have does exist of when code runs.

r - Drop factor from formula when less than two levels -

-
i want able drop term formula based on whether or not factor has less 2 levels. my setup want run large number of same logit models different subsets of data. problem that, subsets, not factors may take 1 value. here example: depvar <- sample(0:1, 100, replace=t) bin1 <- rep(1, 100) cont1 <- rnorm(100) df <- data.frame(depvar=depvar, bin1=bin1, cont1=cont1) formla <- as.formula("depvar ~ bin1 + cont1") logit.reg <- glm(formla, data=df, family=binomial(link=logit)) i able somehow drop bin1 formula automatically when takes 1 value. seems me simple if/else should suffice: if(length(unique(df$bin)) > 1) { formla <- as.formula("depvar ~ bin1 + cont1") } else { formla <- as.formula("depvar ~ cont1") } note bin1 not factor in example (can use as.factor() coerce 1 though)

javascript - How to force TypeScript exports to the end of the JS output? -

-
i use lot of export statements following, cumulate module's exports @ bottom of file: export { foo1 bar1, foo2 bar2, ... } lately have learned that... let foo : number = 0; export { foo bar } ...is not @ same as... let foo : number; foo = 0; export { foo bar } ...because latter delivers undefined in exports.bar . happens because compiled javascript has export statement of exports.bar = foo before assignment. find hardly intuitive. read on typescript module pages, seem miss description of behaviour. there? is there way force output's export statements @ bottom rather right after declaration? thanks. this sounds more bug in typescript. future reference, typescript 1.8 compiles following code: let foo : number; foo = 0; export { foo bar } into javascript: "use strict"; var foo; exports.bar = foo; foo = 0; i tried typescript 2.0 beta, , seems fixes it: "use strict"; var foo; exports.bar = foo; exports.bar = foo = 0;

How to solve longEnough?. In Haskell -

-
longenough n xs : checks if list has more n elements. examples: longenough 2 [1..5] == true longenough 3 [1,2,3] == false longenough 0 [] == false longenough 20 [1..] == true i guess homework , still learning basics i'll start giving hints using recursion instead of foldr (as @dfeuer proposed): first start noting obvious cases: if xs = [] result false (assuming don't care negative n in strange ways) if n = 0 , xs non-empty it's true in other cases have n > 0 xs has more 1 element maybe have recursive idea break last case down? here skeleton: longenough :: int -> [a] -> bool longenough _ [] = false longenough 0 _ = true longenough n (_:xs) = let n' = (n-1) in undefined for cases - if look closely you'll see added more hints on solution. ps maybe want think negative n , should happen ... did not here if know foldr should try implement using foldr too solution seems there no more ...
