sass - How can I use part of a CSS function name (eg. 'Y' from 'translateY') as a variable? -


not sure how ask one, i'll demonstrate code:

i have mixin i'm hoping can refactor:

@mixin center-align($dir, $position: relative) {   position: $position;    @if $dir == y {     top: 50%;     transform: translate + inspect($dir) + (-50%);   } @else if $dir == x {     left: 50%;     transform: translatex(-50%);   } @else {     top: 50%;     left: 50%;     transform: translate(-50%,-50%);   }  }

instead of doing @if loop, i'd this:

transform: translate + $dir + (-50%);

or 

transform: translate+$dir(-50%);

or

transform: translate + inspect($dir) + (-50%);

but each of these outputs variation of this:

transform: translatey-50%;

without parens.

you want use string interpolation here:

.foo {   $foo: 'x';   transform: #{"translate#{$foo}(50%)"}; }

output:

.foo {   transform: translatex(50%); }

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...
