CO_FUN

Fun and Functional programming with C++20 Corotines

<To Be Written>

Building

There’s a decent chance that `make` will work. Otherwise try something like

“` shell make -k TOOLCHAIN=gcc-11 BUILD_TYPE=RelWithDebInfo “`

The makefile is there to drive the cmake build through its states. It’s not complicated, nor necessary.

Code organization

src/delay

delayed evaluation circa 2015 (Meh)

src/co_fun

new fun code using coroutines

Components

Holder

Used to hold the pending results for the coroutine

Based on the holder described in “The Old New Thing”

Lazy

A coroutine promise holder that mediates the result of a single function call.

Thunk

A result of a function call that when you think you want the result, it may already have been thunk. Shareable.

Stream

Fun with suspended function calls. A cons cell is a value and a thunk to the next value. A cons stream is a series of lazy values. From this, the list monad is built, and much of `do` notation desugaring. ConsStream models a range.
