Here's a script to get you started

git clone https://github.com/adamdruppe/dmd.git
cd dmd
git checkout interp
rdmd compiler/src/build.d

I don't want to copy files anywhere, so the user has to do that manually:

Copy dmd from the generated executable to your D bin installation folder

Example:

copy generated\windows\release\64\dmd.exe C:\d\dmd2\windows\bin64

Copy druntime/src/core/interpolation.d to your corresponding druntime folder + import

Example:

copy druntime/src/core/interpolation.d C:\d\dmd2\src\druntime\import\core\

Now try string interpolation:

import std.stdio;

void main()
{
	string name = "Johan";
	int age = 37;
	int iq = 8001;
	int coffees = 1000;

	writeln(i"Your name is $name and you're $age years old");
	writeln(i"You drink $coffees cups a day and it gives you $(coffees + iq) IQ");
}

Output:

Your name is Johan and you're 37 years old
You drink 1000 cups a day and it gives you 9001 IQ

We just need support for it in the tools, then D will be a Dream come true

Same instructions for DIP1027:

git clone https://github.com/WalterBright/dmd.git
cd dmd
git checkout dip1027
rdmd compiler/src/build.d

Then same instructions as above but without the need to copy interpolation.d

First of all thanks for writing this.

Well this seems pretty nice... What DIP number is this? - I'd like to read why it was rejected.

Which one did you try?

The first one is YAIDIP:
https://github.com/John-Colvin/YAIDIP

and the second one is DIP1027:
https://github.com/dlang/DIPs/blob/master/DIPs/rejected/DIP1027.md

Make sure you try them both

Note: The YAIDIP is now superseed by the 1036e.
