let's have single master branch , push new code feature-a branch, sub-branch master : feature-a master now have feature-a branch checked out. later different person merges feature-a master , closes feature-a branch: master (merged feature-a) feature-a master but sourcetree stuck old feature-a branch , have resort using reset --hard move latest master commit , rid of feature-a references. is there way make process more streamlined? ideally script/simple button sequence automatically move latest master commit, the key thing remember here feature-a has been merged master , feature-a has not been updated. therefore feature-a still - middle commit in second diagram. if reset --hard , you're forcing feature-a branch point master , isn't has happened in remote repository. instead want checkout master , continue working; or perhaps create new feature branch starting @ master .

i have curious question. have aar library, contains , uses native .so library. now, want write lib, depends on library , has native part depending on native lib first lib. dependent library uses both native code , java wrappers first lib. i wonder, there way, how standard gradle dependency(with copied headers files first lib)? or have build second lib directly sources? why need this: have multiplatform lib basic functionality, android aar. lib can used in standard android app , use in multiple projects, have no native code. but in 1 app want write multiplatform shared app code, depending on lib , want have these libs separated. thanks! here workable example basic on opencv , can same first lib . prepare first lib following package jar , *.so , , exported headers (see file opencv4android/opencv/build.gradle in linked project how append headers aar). you first.aar example building of first lib . using first lib in other projects add first.aar in other ...

is there better way "idiom"? if(state s = loadsomething()) { } else return s; in other words, want something, may return error (with message) or success state, , if there error want return it. can become repetitive, want shorten it. example if(state s = loadfoobar(&loadpointer, &results)) { } else return s; if(state s = loadbaz(&loadpointer, &results)) { } else return s; if(state s = loadbuz(&loadpointer, &results)) { } else return s; this must not use exceptions favor otherwise (unsuitable build). write little class booleannegator<state> stores value, , negates boolean evaluation. want avoid doing ad-hoc, , prefer boost/standard solution. you do: for (state s = loadsomething(); !s; ) return s; but not sure if more elegant, , less readable...

asume website domain.com, store page, domain.com/store adding id = "itemid" every item can let users visit item directly by: domain.com/store#itemid usual anchor behavior. however, need little more complex. assume item hierarchy follows: <div id="item1> <div class="images"></div> </div> i want user directly reach "images" box of given item using anchor-like addressing. such as domain.com/store#itemid.images what's best approach this? something should work, split hash 2 parts: id , class use using javascript or jquery find element , scroll view. hash = window.location.hash.split('.') document.getelementbyid(hash[0]).getelementsbyclassname(hash[1])[0].scrollintoview(true);
