# Fiona

Fiona is a coroutine runtime library built on top of io_uring and C++20's

coroutines. This means that Fiona is a Linux-only library.

Fiona includes a vcpkg.json for easy dependency management.

## Useful Scripts for Developers

### Testing

run.sh

```bash

#!/bin/bash

set -e

clear

ulimit -n 25000

ninja -C __build__ fiona_verify_interface_header_sets

ctest \

  --test-dir __build__/ \

  -j20 \

  --output-on-failure \

  --schedule-random \

  "$@"

```

toolchain.cmake

```cmake

include(/home/exbigboss/cpp/vcpkg/scripts/buildsystems/vcpkg.cmake)

list(APPEND CMAKE_PREFIX_PATH /home/exbigboss/cpp/__install__)

set(CMAKE_CXX_STANDARD 20)

set(CMAKE_CXX_FLAGS_INIT "-Wall -Wextra -pedantic -fsanitize=address,undefined")

```

For emulating a CI setup locally, use something like:

```bash

#!/bin/#!/bin/bash

export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer-18

export UBSAN_OPTIONS=print_stacktrace=1

export ASAN_OPTIONS="detect_invalid_pointer_pairs=2:strict_string_checks=1:detect_stack_use_after_return=1:check_initialization_order=1:strict_init_order=1"

set -e

clean() {

  input=$1

  str=${input//[^a-zA-Z0-9]/}

  echo "$str"

}

build_and_test() {

  local cc

  cc=$(clean "$1")

  local build_type

  build_type=$(clean "$2")

  local build_dir

  local cxx_flags_init

  if [ -z "$3" ]; then

    build_dir=__ci_build__/${cc}/${build_type}/nosan

    cxx_flags_init="-Wall -Wextra -pedantic"

  else

    local sanitizers

    sanitizers=$(clean "$3")

    build_dir=__ci_build__/${cc}/${build_type}/${sanitizers}

    cxx_flags_init="-Wall -Wextra -pedantic -fsanitize=$3"
