Is it possible to define an alias for something like
mixin(import("local_function_file.d"));
to write only
use_local_function;
which will be translated to:
mixin(import("local_function_file.d"));
(this additionally needs the file local_function_file.d in

-J./source as parameter for dmd aka. dflags "-J./source" in

nope. the best you can get is `mixin use_local_function;`.
Would there be an advantage compared to a simple `import
local_function_file;`?
i doubt so.
So my "solution" on how to get a short cut for using:
writeln(mixin(interp!"${name} you are app. ${age*365} days old"));
// first place in source/exho.d the following code:
auto mixinter(string x)(){return mixin(interp!x);}
auto exho(string x)(){return mixin("writeln("~interp!x~")");}
later compile this with -J./source
source/app.d:
import scriptlike;
auto insert(string name)(){return import(name);}
alias insert!"exho.d" use_exho;
void main()
{
auto name = userInput!string("Please enter your name");
auto age = userInput!int("And your age");
//Now you can write in every scope you need it:
mixin(use_exho);
exho!"${name} you are app. ${age*365} days old";
// Which looks little nicer than:
// writeln(mixin(interp!"${name} you are app. ${age*365} days
old"));
// or if you need the result in a var:
mixin(use_exho);
auto var = mixinter!"${name} you are app. ${age*365} days old";
writeln(var);
}
you may even name the alias just exho and write:
alias insert!"exho.d" exho;
mixin(exho);
exho!"${name} you are app. ${age*365} days old";
(exho was derived from shell echo with mi_x_in)
