scala.js - How to get arguments object in scalajs -


in js, can access function arguments through arguments object.

i want same thing somehow in scalajs, because want logging functions , parameters got.

is possible?

as @justin-du-coeur suggested, can use sourcecode this. example:

object test extends js.jsapp {   def main(): unit = {     a(1, "a")     b()     c("foo", "bar", "baz")   }    def trace()(implicit name: sourcecode.name, args: sourcecode.args): unit = {     def makearglist(as: seq[sourcecode.text[_]]): string =       as.map(a => f"${a.source} = ${a.value}").mkstring("(", ", ", ")")      val argstr = args.value.map(makearglist).mkstring("")     println(f"${name.value}$argstr")   }    def a(arg1: int, arg2: string): unit = {     trace()   }    def b(): unit = {     trace()   }    def c(x: string*): unit = {     trace()   } }

the output follows:

[info] running test a(arg1 = 1, arg2 = a) b() c(x = wrappedarray(foo, bar, baz))

as can see, trace can capture needs context, result more boilerplate free js solution can think of.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
