sbt - Why doesn't the Def.inputTask macro work in Scala 2.11.1? -

-

i'm using scala 2.11.1 , sbt 0.13.5.

i have sbt plugin contains helper function create input tasks follows (the implementation stripped away it's irrelevant problem):

def register(name: string, description: string): def.setting[inputtask[unit]] = {     inputkey[unit](name, description) <<= def.inputtask {          println("test")     } }

this function compiles , works fine in scala 2.10.4, once switch 2.11.1 fails following error:

can't expand macros compiled previous versions of scala

is def.inputtask macro broken in scala 2.11.1, or missing glaring detail?

right above function residing in simplest sbt plugin imaginable. there no dependencies @ all, either.

sbt 0.13.x series uses scala 2.10.x when loads up, sbt 0.13.x must compiled against scala 2.10, , sbt plugins 0.13.x.

note: sbt 0.13 can define scala projects using 2.11.x.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
