Hi all!
I want readable mixin.
I want pass variable to string.
I want string with named args.
Like this:

    enum JMP_ADDR_R = "RAX";

    mixin( format!"asm {
        jmp [JMP_ADDR_R];
   }"( JMP_ADDR_R ));    // IT NOT WORK

Not this:

    enum JMP_ADDR_R = "RAX";

    mixin( format!"asm {
        jmp [%s];
   }"( JMP_ADDR_R ));    // WORK, BUT NOT-READABLE

In large code named identifiers more readable.

In future it will used in jump table, like this:

    mixin( format!"asm {
        lea JMP_ADDR_R, qword ptr [ JMP_I_R * PTR_SIZE + TBL_ADDR ];
        jmp [JMP_ADDR_R];
    }"( JMP_I_R, PTR_SIZE, TBL_ADDR, JMP_ADDR_R ));

Please, help me find a solution...
or exists std.format with named args ?
or another solution with named args ?

Without string interpolation the best you can do is https://dlang.org/library/std/conv/text.html

Or write some code yourself, unfortunately

May be.

"String interpolation"

    mixin( format!"asm {
        lea JMP_ADDR_R, qword ptr [ JMP_I_R * PTR_SIZE + TBL_ADDR ];
        jmp [JMP_ADDR_R];
    }"( JMP_I_R, PTR_SIZE, TBL_ADDR, JMP_ADDR_R ));

vs

text()

    mixin( text( "asm {
        lea", JMP_ADDR_R, ", qword ptr [ ", JMP_I_R, " * ", PTR_SIZE, " + ", TBL_ADDR, " ];
        jmp [", JMP_ADDR_R, "];
    }"));

"String interpolation" more readable.
"String interpolation" easier to type.
"text()" syntax is highlighted,
Thanks for the correct keywords: "String interpolation" - this is what I'm looking for.

Is there a "string interpolation" solution?

scriptlike looks perfecto!

```D
        enum JMP_ADDR_R = ...
        ...

        import scriptlike;
        writeln( mixin(interp!"
            asm {
                lea ${JMP_ADDR_R}, qword ptr [ ${JMP_I_R} * ${PTR_SIZE} + ${TBL_ADDR} ];
                jmp [${JMP_ADDR_R}];
            }
        ") );
```

produced:

```
            asm {
                lea RAX, qword ptr [ RDX * 8 + 5594AA134290 ];
                jmp [RAX];
            }
```

Closed!
scriptlike
Thanks, all!
