d - How do I specialize templates across different modules? -

module a; void foo(t)(){     import std.stdio;     writeln(t.stringof); }  module b; import a;  private alias foo = a.foo; void foo(t: int)(){     import std.stdio;     writeln("special int"); } //app.d void main() {     import a;     import b;     foo!int(); } 

this prints int instead of special int. possible specialize templates across different modules?

can assume answer d template specialization in different source file still relevant today?

your alias wrong , import introduces ambiguities. if want publicly overloadable, don't make alias private!

once alias made public (the default btw), compiling spit out name conflict error:

iii.d(6): error: a.foo(t)() @ ii.d(2) conflicts b.foo @ i.d 

then, simple matter of disambiguating (specifying b.foo!int()), or better yet, removing unnecessary import a usage point.

//app.d void main() {     import b;     foo!int(); } 

special int!

for more complex cases, can make wrapper template , forward arguments, here simple alias overloading - when done alias foo = a.foo;, no private, trick.
