Annotations lets you mark points and ranges inside source code, for tests:
Annotations Example(R"cpp( int complete() { x.pri^ } // ^ indicates a point void err() { [["hello" == 42]]; } // [[this is a range]] $definition^class Foo{}; // points can be named: "definition" $(foo)^class Foo{}; // ...or have a payload: "foo" $definition(foo)^class Foo{}; // ...or both $fail(runtime)[[assert(false)]] // ranges can have names/payloads too )cpp");
StringRef Code = Example.code(); // annotations stripped. std::vector<size_t> PP = Example.points(); // all unnamed points size_t P = Example.point(); // there must be exactly one llvm::Range R = Example.range("fail"); // find named ranges
Points/ranges are coordinated into code() which is stripped of annotations.
Names consist of only alphanumeric characters or '_'. Payloads can contain any character expect '(' and ')'.
Ranges may be nested (and points can be inside ranges), but there's no way to define general overlapping ranges.
FIXME: the choice of the marking syntax makes it impossible to represent some of the C++ and Objective C constructs (including common ones like C++ attributes). We can fix this by:

Returns the mapping of all names of points marked in the text to their position.
Unnamed points are mapped to the empty string. The positions are sorted. FIXME Remove this and expose All directly (currently used out-of-tree)

Unnamed ranges are mapped to the empty string. The ranges are sorted by their start position.
