an op precedence parser has stack , input buffer. i believe after popping, "id" token reduced variable "e". for every pop of "id" token stack after seeing mathematical operator in input, popped token kept? if input id+id*id$ , time $ reached, "id"s have been popped. kept? assuming goal build ast, id s (and other operand tokens such literal constants) put ast node created reduction. if you're directly evaluating or generating three-address code or ..., answer differ slightly. however, broad outline same: operator-precedence parsing bottom-up parse algorithm in right-hand side of production reduced corresponding non-terminal (on left-hand side of production) when it's last input symbol has been read (and lookahead indicates correct action reduction).

in paperjs project have bunch of objects have circle path associated them. these paths each have mouse functions. what i'd create links between 2 circles when clicking on one, dragging mouse, , releasing mouse button on circle. for use paperjs onmousedown , onmouseup events, implemented inside object: function circleobj() { // object constructor this.circle = new path(...); this.circle.onmousedown = function(event) { //eventstuff } } where this.circle circle path. the problem when release mouse button no longer linked circle, , onmouseup function doesn't execute until click on actual circle again. therefore doesn't allow drag , drop on other circle, since 'drop' action doesn't register. how can have onmouseup event register , linked circle onmousedown event took place? if want keep mouse events tied constructor, think easiest keep initial point in global variable. it's cleaner adding , removing tool event view ,...

when args dynamic how define format,where args 1 can define format “sss %d”? official javadoc ( https://docs.oracle.com/javase/7/docs/api/java/util/formatter.html ) states 3 kinds of formatting types: general, character , number : %[argument_index$][flags][width][.precision]conversion dates: %[argument_index$][flags][width]conversion others: %[flags][width]conversion none of them allows use conditions represent in case of non matching args ... . i think parse both parameters: string format , object[] arguments, create coherent pair of parameters depending on runtime circumstances.

question experienced pandas users on approach working dataframe data. invariably want use pandas explore relationships among data elements. use groupby type functions summary level data on subsets of data. use plots , charts compare 1 column of data against another. i'm sure there other application haven't thought of. when speak other novice users myself, try extract portions of "large" dataframe smaller dfs sorted or formatted run applications or plot. approach has disadvantages in if strip out subset of data smaller df , want run analysis against column of data left in bigger df, have go , recut stuff. my question - best practices more experienced users leave large dataframe , try syntactically pull out data in such way effect same or similar cutting out smaller df? or best cut out smaller dfs work with? thanks in advance.
