javascript - Accessing a previously fullfilled promise result in a promises chain -

this question has answer here: how access previous promise results in .then() chain? 15 answers what correct pattern, when coding promises, access data coming long before in chain of promises? for example: do_a.then(do_b).then(do_c).then(do_d).then(do_e_withthedatacomingfrom_a_and_c_onlywhen_d_issuccesfullycompleted) my current solution: passing along single json structure through chain, , let each step populate it. opinion that? i don't think there's 1 "correct" pattern this. solution sounds neat, however, it's bit tightly coupled. may work great situation, see few problems general pattern: participating steps need agree on structure of collector object. every step needs participate in @ least forwarding of object, can tedious if chain long , need previous data occurs sporadically. inflexible insertion of steps not written (c...

java - Progress bar on console using Log4J or LogBack -

i have console application prints output using log4j. useful can implement switch optionally show debug messages, though hidden default. this application has long running actions progress bar appropriate. what best way implement using either log4j or logback ? to write progress bar or sort of updating text console, end output \r (carriage return) instead of \n (new line) next line overwrites it. question goes more detail. f-ansi library enables generate nice-looking console output including overwriting previous line. but if set on using logging framework, not not possible, it's not want. chrism suggests, right way log progress log new line every percent done far. way, can see both program doing , how far along in context. what sounds want separate logging program's actual output (this idea, disregarding progress bar issue). use logging framework log information program's execution; things or debugging interested in. actual program's out...
