the preferred approach use similar commented out line below. def main(args: array[string]) { // val (dbpropsfile, tsvfile, dbtable) = args val dbpropsfile = args(0) val tsvfile = args(1) val dbtable = args(2) however having little quarrel compiler on it: error:(13, 9) constructor cannot instantiated expected type; found : (t1, t2, t3) required: array[string] val (dbpropsfile, tsvfile, dbtable) = args ^ so told should easy few points out there. use val array(dbpropsfile, tsvfile, dbtable) = args scala> val array(a,b,c) = array(1,2,3) a: int = 1 b: int = 2 c: int = 3 scala> res0: int = 1

i trying put powershell script read data csv (it tab separated , not csv so, we'll use commas) , import data powershell multidimensional array. csv has following data: empid,name,dept 12345,john,service 56789,sarah,sales 98765,chris,director my script follows: $temp=gc "temp.csv" $array=@() $temp | foreach{ $elements=$_.split(",") $array+= ,@($elements[0],$elements[1],$elements[2]) } foreach($value in $array) { write-host "empid =" $value[0] "and name =" $value[1] "and dept =" $value[2] } the above works, able refer array elements more proper name because there lot more elements shown above , gets confusing. this, i’ve tried use hash tables, defining new objects, members, types, etc. never seem work properly. may wrong feel i’m running in circle , may lost. basically, want is, instead of using: write-host "empid =" $value[0] "and name =" $value[1] "and dept =" $value[2] ...

when have '+' or '&' character in page title. words after '+'/'&' characters either truncated or '+'/'&' filtered page title. behavior seem random after experimenting few different combinations. length of title shouldn't issue because short of 40 characters. does google analytics have limitation or restriction on use of '+' , '&' characters in page title? thanks.

why create "implicitly unwrapped optional" vs creating regular variable or constant. if know can unwrapped why create optional in first place? example, why this: let somestring : string! = "this string" going more useful vs: let somestring : string = "this string" if “optional indicate constant or variable allowed have 'no value'” , “sometimes clear program’s structure optional have value after value first set” , point of making optional in first place? if know optional going have value... doesn't make it.... not optional? consider case of object may have nil properties while it's being constructed , configured, immutable , non-nil afterwards (nsimage treated way, though in case it's still useful mutate sometimes). implicitly unwrapped optionals clean code deal, relatively low loss of safety (as long 1 guarantee held, safe). (edit) clear though: regular optionals preferable.
