haskell - How to reload updated file in Threepenny-gui 0.6? -


the threepenny-gui changelog (https://hackage.haskell.org/package/threepenny-gui-0.6.0.1/changelog) reads: "the functions loadfile , loaddirectory have been removed, felt jsstatic option sufficient use cases."

my question is: how can reload image updated during execution without loadfile?

with threepenny-gui 0.5 used following code:

redraw :: ui.element -> ioref comptree -> (maybe vertex) -> ui () redraw img treeref mcv   = tree <- ui.liftio $ readioref treeref        ui.liftio $ writefile ".hoed/debugtree.dot" (shw $ summarize tree mcv)        ui.liftio $ system $ "dot -tpng -gsize=9,5 -gdpi=100 .hoed/debugtree.dot "                           ++ "> .hoed/wwwroot/debugtree.png"        url <- ui.loadfile "image/png" ".hoed/wwwroot/debugtree.png"        ui.element img # ui.set ui.src url

when, threepenny-gui 0.6, set jsstatic just "./.hoed/wwwroot", following code (obviously) results in gui showing initial image there when application started: 

redraw :: ui.element -> ioref comptree -> (maybe vertex) -> ui () redraw img treeref mcv   = tree <- ui.liftio $ readioref treeref        ui.liftio $ writefile ".hoed/debugtree.dot" (shw $ summarize tree mcv)        ui.liftio $ system $ "dot -tpng -gsize=9,5 -gdpi=100 .hoed/debugtree.dot "                           ++ "> .hoed/wwwroot/debugtree.png"        ui.element img # ui.set ui.src "static/debugtree.png"        return ()

my full code threepenny-gui 0.5 here: https://github.com/maartenfaddegon/hoed/blob/master/debug/hoed/demogui.hs

(author here.) apparently, didn't consider use case when removing these functions. :-) can add them in if like, make issue on github?

there various methods on javascript side reload file @ url. see instance question "refresh image new 1 @ same url".

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
