Reusable Standalone C++ Libraries and Modules

The goal of this project is to provide C++17 and C++20 developers with convenient and minimal cross-platform C++ utility libraries. All of the modules are heavily performance oriented and provides the least amount of overhead possible.

Currently supported and tested platforms are VC++,Clang on Windows and GCC,Clang on Ubuntu,iOS,Android

rpp/strview.h - A lightweight and powerful string utilities

An extremely fast and powerful set of string-parsing utilities. Includes fast tokenization, blazing fast number parsers, extremely fast number formatters, and basic string search functions and utilities, all extremely well optimized.

This strview module works on UTF-8 strings, and since std::codecvt_utf8 already exists, there is no plan to add a Wide strview.

The string view header also provides examples of basic parsers such as line_parser, keyval_parser and bracket_parser. It's extremely easy to create blazing fast parsers with rpp::strview

rpp::strview text = buffer; // or { buffer.data(), buffer.size() };
rpp::strview line;
while (text.next(line, '\n')) // or "\r\n"
{
    line.trim(); // in-place trim
    if (line.empty() || line.starts_with('#'))
        continue;
    if (line.starts_withi("numObJecTS")) // case insensitive search
    {
        objects.reserve(line.to_int()); // to_int(),to_bool(),to_float(),to_double()
    }
    else if (line.starts_with("object")) // "object scene_root 192 768"
    {
        // next(' ') tokenizes the line by skipping over the entries
        line.skip(' '); // skip over "object "
        rpp::strview name = line.next(' '); // "scene_root"
        int posX = line.next_int(); // 192
        int posY = line.next_int(); // 768
        objects.push_back(scene::object{name.to_string()/*std::string*/, posX, posY});
    }
}

rpp/file_io.h - Simple and fast File IO

This is an extremely useful cross-platform file and filesystem module. It provides all the basic functionality for most common file operations and path manipulations.

Example of using file_io for basic file manipulation

#include <rpp/file_io.h>
using namespace rpp;

void fileio_read_sample(strview filename = "README.md"_sv)
{
    if (file f = { filename, READONLY })
    {
        // reads all data in the most efficient way
        load_buffer data = f.read_all(); 
        
        // use the data as a binary blob
        for (char& ch : data) { }
    }
}
void fileio_writeall_sample(strview filename = "test.txt"_sv)
{
    string someText = "/**\n * A simple self-expanding buffer\n */\nstruct";
    
    // write a new file with the contents of someText
    file::write_new(filename, someText.data(), someText.size());
    
    // or just write it as a string 
    file::write_new(filename, someText);
}
void fileio_info_sample(strview file = "README.md"_sv)
{
    if (file_exists(file))
    {
        printf(" === %s === \n", file.str);
        printf("  file_size     : %d\n",   file_size(file));
        printf("  file_modified : %llu\n", file_modified(file));
        printf("  full_path     : %s\n",   full_path(file).data());
        printf("  file_name     : %s\n",   file_name(file).data());
        printf("  folder_name   : %s\n",   folder_name(full_path(file)).data());
    }
}
void fileio_path_manipulation(strview file = "/root/../path\\example.txt"_sv)
{
    printf(" === %s === \n", file.str);
    printf("  full_path     : %s\n", full_path(file).data());
    printf("  merge_dirups  : %s\n", merge_dirups(file).data());
    printf("  file_name     : %s\n", file_name(file).str);
    printf("  file_nameext  : %s\n", file_nameext(file).str);
    printf("  file_ext      : %s\n", file_ext(file).str);
    printf("  folder_name   : %s\n", file_ext(file).str);
    printf("  folder_path   : %s\n", file_ext(file).str);
    printf("  normalized    : %s\n", normalized(file).data());
    printf("  path_combine  : %s\n", path_combine(folder_name(file), "another.txt").data());
}
void fileio_listing_dirs(strview path = "../"_sv)
{
    printf(" working dir   : %s\n", working_dir().data());
    printf(" relative path : %s\n", path.str);
    printf(" full path     : %s\n", full_path(path).data());
    
    vector<string> cppFiles = list_files_recursive(path, "cpp");
    for (auto& relativePath : cppFiles)
        printf("  source  : %s\n", relativePath.data());
    
    vector<string> headerFiles = list_files_fullpath("./rpp", "h");
    for (auto& fullPath : headerFiles)
        printf("  header  : %s\n", fullPath.data());
}

rpp/delegate.h - Fast function delegates and multicast delegates (events)

Class	Description
`delegate<f(a)>`	Function delegate that can contain static functions, instance member functions, lambdas and functors.
`event<void(a)>`	Multicast delegate object, acts as an optimized container for registering multiple delegates to a single event.

Examples of using delegates for any convenient case

void delegate_samples()
{
    // create a new function delegate - in this case using a lambda
    delegate<void(int)> fn = [](int a) { 
        printf("lambda %d!\n", a); 
    };
    
    // invoke the delegate like any other function
    fn(42);
}
void event_sample()
{
    // create an event container
    event<void(int,int)> onMouseMove;

    // add a single notification target (more can be added if needed)
    onMouseMove += [](int x, int y) { 
        printf("mx %d, my %d\n", x, y); 
    };
    
    // call the event and multicast to all registered callbacks
    onMouseMove(22, 34);
}

rpp/future.h - Composable Futures with C++20 Coroutines Support

This makes it easy to write asynchronous cross-platform software with minimal dependencies. The main API consists of rpp::async_task() which uses rpp/thread_pool.h to launch the task in background.

template<typename Task>
auto async_task(Task&& task) noexcept -> cfuture<decltype(task())>;

The future object rpp::cfuture<T> provides composable facilities for continuations.

then() allows chaining futures together by passing the result to the next future and resuming it using rpp::async_task()
continue_with() allows to continue execution without returning a future, which is useful for the final step in chaining
detach() allows to abandon this future by moving the state into rpp::async_task() and waiting for finish there

Example with classic composable futures using callbacks

    rpp::async_task([=]{
        return downloadZipFile(url);
    }).then([=](std::string zipPath) {
        return extractContents(zipPath);
    }).continue_with([=](std::string extractedDir) {
        callOnUIThread([=]{ jobComplete(extractedDir); });
    });

Continuations with exception handlers: allows to forward the task result to the next task in chain, or handle an exception of the given type. This allows for more complicated task chains where exceptions can be used to recover the task chain and return a usable value.

    rpp::async_task([=] {
        return loadCachedScene(getCachePath(file));
    }, [=](invalid_cache_state& e) {
        return loadCachedScene(downloadAndCacheFile(file)); // recover
    }).then([=](std::shared_ptr<SceneData> sceneData) {
        setCurrentScene(sceneData);
    }, [=](scene_load_failed& e) {
        loadDefaultScene(); // recover
    });

Example with C++20 coroutines. This uses co_await to run each lambda in a background thread. This is useful if you are upgrading legacy Synchronous code which doesn't have awaitable IO.

The lambdas are run in background thread using rpp::thread_pool

using namespace rpp::coro_operators;
rpp::cfuture<void> downloadAndUnzipDataAsync(std::string url)
{
    std::string zipPath = co_await [&]{ return downloadZipFile(url); };
    std::string extractedDir = co_await [&]{ return extractContents(zipPath); };
    co_await callOnUIThread([=]{ jobComplete(extractedDir); });
    co_return;
}
rpp::cfuture<void> coroRunnerExample()
{
    co_await downloadAndUnzipDataAsync("https://example.com");
}

Some additional utilities

cfuture<T> make_read_future(T&& value) Creates a cfuture which is already completed.
cfuture<T> make_exceptional_future(E&& e) Creates a cfuture which is already errored with the exception.
wait_all(const std::vector<cfuture<T>>& vf) Given a vector of futures, waits blockingly on all of them to be completed.
std::vector<T> get_all(const std::vector<cfuture<T>>& vf) Blocks and gathers the results from all of the futures
std::vector<T> get_tasks(std::vector<U>& items, const Launcher& futureLauncher) Used to launch multiple parallel Tasks and then gather the results.
std::vector<T> get_async_tasks(std::vector<U>& items, const Callback& futureCallback) Used to launch multiple parallel Tasks and then gather the results.
void run_tasks(std::vector<U>& items, const Launcher& futureLauncher) Used to launch multiple parallel Tasks and then wait for the results.
