Bolts Meta Programming Utility Library

Full API docs available here

Bolts is a utility library for the D programming language which contains a number of static reflection utilties that query compile time entities (traits) or transform them (meta). General utilties are in the modules traits and meta, and more specific ones are in dedicated modules (i.e. bolts.members provides utilities over a type's members).

Modules:

• meta: has functions that result in compile time entity transofrmations, including:
  • TypesOf, Flatten, AliasPack, staticZip
• traits: has general utitlites that can query compile time entities. including:
  • isFunctionOver, isUnaryOver, isBinaryOver, hasProperty, propertySemantics, areCombinable, isManifestAssignable, isOf, isSame, isNullType, isNullable, StringOf, isRefType, isValueType
• members: has functions that allow you to query about the members of types
  • staticMembers, memberFunction, hasMember (not eponymous)
• range: query ranges
  • isSortedRange, sortingPredicate, CommonTypeOfRanges
• aa: has functions that act on associative arrays
  • isKey (not eponymous)
• assume: can alias functions to different attributed types. Useful for debugging.
  • nogc_, pure_
• iz: super non-eponymous template that provides a lot of the functionality that's in the traits module with a different sytax that allows their usage in meta functions as well.

Most functions here operate on any compile time entity. For example isUnaryOver works in both these situatons:

int i;
void f(int) {}
isFunctionOver!(f, int);
isFunctionOver!(f, 3);
isFunctionOver!(f, i);

Iz super template

The iz super template. Has a lot of the traits on types encapulated in one place. So if there's a trait that tells you something about a compile time entity, chances are iz will have it. E.g:

void f(int, float, string) {}
iz!f.functionOver!(int, float, string);
iz!f.functionOver!(3, float, "");
