Hello,

I want to use some static contents in my program, e.g, a CSS file, a long listing. To help deployment process I'd like to have them embedded in the final binary file.

Is there any convenient way to support this? Maybe I need a tool/library to load file contents and generate D-code at run-time ?

Thanks for your reading.

import can do this, basically it gives you an array that you can cast to ubyte[] for binary too, be careful with enums though, because enum arrays will allocate every time you access it

string data = import("strings.txt");

However for security reasons it only looks in folders which you pass with -J flag
or with dub using "stringImportPaths"

Arrays yes, but not strings. So you can do `enum data = import("strings.txt");`.
