describe.d

describe.d is a library that provides a structured interface to introspect DLang source code.

Usage

Introspection

The library provides the describe template which returns a structure with the introspection result:

import described;

/// Introspecting modules
assert(describe!(std.array).name == "module array");
assert(describe!(std.array).fullyQualifiedName == "std.array");
assert(describe!(std.array).functions.length == 1);
assert(describe!(std.array).templates.length == 31);

/// Introspecting aggregates
struct MyStruct {
  void callMe() {
  }
}

assert(describe!MyStruct.name == "MyStruct");
assert(describe!MyStruct.methods.length == 1);
assert(describe!MyStruct.methods[0].name == "callMe");
assert(describe!MyStruct.methods[0].returns.name.should.equal("void"));

/// Introspecting methods
assert(describe!(MyStruct.callMe).name == "MyStruct");
assert(describe!(MyStruct.callMe).returns.name.should.equal("void"));

Given an introspected Type like a class or struct, it can be converted to the D type using fromType:

  alias T = fromType!(describe!RandomClass.type);

  static assert(is(T == RandomClass));

Filtering

The library provides the where module which allows you to filter various describe results.

Asserts

The library provides the has module which allows you to check states of the various describe results.
