namespace

Namespace gh4ck3r is applied to entire snippets.

Type

LazyGetter

• a type that fetch value from GETTER() on first demand.
• can be assigned with a value prior to GETTER()
• GETTER is gone once it has a value by any means.

Logger

• std::ostream wrapper that is capable of indentation.
• Indentation level can be adjusted via indent(), unindent() method or manipulator like one defined in iomanip (e.g. std::hex).

Functionality

hexdump

Dump linear buffer to std::string. Following forms are possible.

• hexdump(ptr, len): dump from given ptr to len in byte unit.
• hexdump(beg, end): dump iterator based range

concatenate

Concatenate constexpr containers, i.e. std::array, std::string_view.

• concat<string_view, string_view, ...>(): concatenate given string_views
  • Template parameters should have static storage class.
  • Concatenated string_view ended with null.
• concat(std::array...): concatenate given std::arrays

recipe

Function recipe(invocable1, invocable2, ...) returns a lambda function which forward given arguments to invocable1 and forward its return to next one until last argument which returns final return value. It's similar to std::range from C++20 semantically.
