i have 2 arrays of hashes this: a = [ { car_id: 1, motor_id: 1, quantity: 5 }, { car_id: 1, motor_id: 2, quantity: 6 }, { car_id: 5, motor_id: 3, quantity: 3 } ] b = [ { car_id: 1, motor_id: 1, quantity: 2 }, { car_id: 1, motor_id: 2, quantity: 3 } ] i want substract quantities each hash in b hashes in a hashes have same car_id & motor_id . so, expected result be: c = [ {car_id: 1, motor_id: 1, quantity: 3}, {car_id: 1, motor_id: 2, quantity: 3}, {car_id: 5, motor_id: 3, quantity: 3 } ] what way in ruby? thoughts iterate on a , , each element find if there in b have same car_id , motor_id , if so, substract, , continue. i suggest first create hash bqty b that, each element (hash) g of b , maps [g[:car_id], g[:motor_id]] g[:quantity] : bqty = b.each_with_object({}) {|g,h| h[[g[:car_id], g[:motor_id]]] = g[:quantity]} #=> {[1, 1]=>2, [1, 2]=>3} next, map each element (hash) g of a desired hash. done merging

is possible store length on observable array in observable variable , bind view, this? self.myarray = ko.observablearray([]); self.myarraylength = self.myarray().length; //bind in view self.observelength = ko.observable(self.myarraylength); when alert myarray length seems update proper, cant update in view? because myarraylength isn't observable, won't update when observable does. need computed function instead. you should have: self.myarray = ko.observablearray([]); // bind in view self.observelength = ko.computed(function(){ return self.myarray().length; });

in sphinx, file links can generated using following syntax: `name_of_file.js <some/location/name_of_file.js>`_ in conf.py file, version variable defined can use in .rst files such: |version| including version file link using syntax not allowed: `name_of_file.|version|.min.js <some/location/name_of_file.|version|.min.js>`_ so, how can generate links files named name_of_file.<version_num>.min.js , use version number conf.py? i had need similar , after experimentation have workaround this. warned, crummy solution works. the short answer: you need split parts of link left , right of |version| , use raw html along |version| . .rst this: example of link version in |link-pre|\ |version|\ |link-post| .. |link-pre| raw:: html <a href="some/location/name_of_file. .. |link-post| raw:: html .min.js">name_of_file.min.js</a> the long answer there couple of hurdles need overcome: problem 1: now, |version| sub

i have next function in objective c + (nsstring *)getnslog:(nsstring *)pstring, ...{ va_list args; va_start(args, pstring); nslogv(pstring, args); va_end(args); return [[nsstring alloc] initwithformat:pstring arguments:args]; } how can call function swift or convert code swift such when call function can be: getnslog("my value1 = %@ value2 = %@","hello","world") note second param not have alias how this. getnslog("my value1 = %@ value2 = %@", args:"hello","world") i solved follow: in objective c change code this: +(nsstring*)getnslog:(nsstring*)pstring args:(va_list)args{ nslogv(pstring, args); va_end(args); return [[nsstring alloc] initwithformat:pstring arguments:args]; } in swift app delegate add extension myclass { class func getnslog(format: string, _ args: cvarargtype...) -> nsstring? { return myclass.getnslog(format, args:getvalist(args)) } } now
