You may also wanna check `Lager, a Redux-like library - <https://github.com/arximboldi/lager>`_ for writting interactive - software in C++ using a value-oriented design. - - -Why? ----- - -In the last few years, there has been a growing interest in immutable -data structures, motivated by the horizontal scaling of our processing -power and the ubiquity of highly interactive systems. Languages like -Clojure_ and Scala_ provide them by default, and implementations -for JavaScript like Mori_ and Immutable.js_ are widely used, -specially in combination with modern UI frameworks like React_. - -Interactivity - Thanks to *persistence* and *structural sharing*, new values can - be efficiently compared with old ones. This enables simpler ways of - *reasoning about change* that sit at the core of modern - interactive systems programming paradigms like `reactive - programming`_. - -Concurrency - Passing immutable data structures by value does not need to copy - any data. In the absence of mutation, data can be safely read - from multiple concurrent processes, and enable concurrency - patterns like `share by communicating`_ efficiently. - -Parallelism - Some recent immutable data structures have interesting properties - like :math:`O(log(n))` concatenation, which enable new kinds of - `parallelization algorithms`_. - -.. _clojure: http://clojure.org/reference/data_structures -.. _scala: http://docs.scala-lang.org/overviews/collections/overview.html - -.. _mori: https://swannodette.github.io/mori/ -.. _immutable.js: https://github.com/facebook/immutable-js -.. _react: https://facebook.github.io/react/ - -.. _reactive programming: https://en.wikipedia.org/wiki/Reactive_programming -.. _share by communicating: https://blog.golang.org/share-memory-by-communicating -.. _parallelization algorithms: http://docs.scala-lang.org/overviews/parallel-collections/overview.html - -Features --------- - -Idiomatic - This library doesn't pretend that it is written in Haskell. It - leverages features from recent standards to provide an API that is - both efficient and natural for a C++ developer. - -Performant - You use C++ because you need this. *Immer* implements state of - the art data structures with efficient cache utilization and have - been proven production ready in other languages. It also includes - our own improvements over that are only possible because of the - C++'s ability to abstract over memory layout. We monitor the - performance impact of every change by collecting `benchmark - results`_ directly from CI. - -.. _benchmark results: https://public.sinusoid.es/misc/immer/reports/ - -Customizable - We leverage templates and `policy-based design`_ to build - data-structures that can be adapted to work efficiently for - various purposes and architectures, for example, by choosing among - various `memory management strategies`. This turns - *immer* into a good foundation to provide immutable data - structures to higher level languages with a C runtime, like - Python_ or Guile_. - -.. _python: https://www.python.org/ -.. _guile: https://www.gnu.org/software/guile/ -.. _policy-based design: https://en.wikipedia.org/wiki/Policy-based_design -.. _memory management strategies: https://sinusoid.es/immer/memory.html - -Dependencies ------------- - -This library is written in **C++14** and a compliant compiler is -necessary. It is `continuously tested`_ with Clang 3.8 and GCC 6, but -it might work with other compilers and versions. - -No external library is necessary and there are no other requirements. - -.. _continuously tested: https://travis-ci.org/arximboldi/immer - -Usage ------ - -This is a **header only** library. You can just copy the ``immer`` -subfolder somewhere in your *include path*. - -If you are using the `Nix package manager`_ (we strongly recommend it) -you can just:: - - nix-env -if https://github.com/arximboldi/immer/archive/master.tar.gz - -Alternatively, you can use `CMake`_ to install the library in your -system once you have manually cloned the repository:: - - mkdir -p build && cd build - cmake .. && sudo make install - -.. _nix package manager: https://nixos.org/nix -.. _cmake: https://cmake.org/ - -Development ------------ - -In order to develop the library, you will need to compile and run the -examples, tests and benchmarks. These require some additional tools. -The easiest way to install them is by using the `Nix package -manager`_. At the root of the repository just type:: - - nix-shell - -This will download all required dependencies and create an isolated -environment in which you can use these dependencies, without polluting -your system. - -Then you can proceed to generate a development project using `CMake`_:: - - mkdir build && cd build - cmake .. - -From then on, one may build and run all tests by doing:: - - make check - -In order to build and run all benchmarks when running ``make check``, -run ``cmake`` again with the option ``-DCHECK_BENCHMARKS=1``.

In the context of data-structures, this property of -preserving old values is called **persistence**. - -Most of these containers use data-structures in which these operations -can be done *efficiently*. In particular, not all data is copied when -a new value is produced. Instead, the new values may share, -internally, common data with other objects. We sometimes refer to -this property as **structural sharing**. This behaviour is -transparent to the user. - -Assigment ---------- - -We are sorry, we lied. These containers provide *one mutating -operation*: **assignment** --- i.e. ``operator=``. - -There is a good reason: without ``operator=`` everything becomes -complicated in C++. For example, one may not contain non-assignable -types in many standard containers, assignment would also be disabled -from your custom types holding immutable containers, and so on and so -forth. - -C++ is a multi-paradigm language with an imperative core. Thus, it is -built on the foundation that *variables* can be mutated --- -i.e. assigned to. We don't want to ride against this tide. What we -want to prevent is in-place *object* manipulation. Because of C++ -semantics, *variable* assignment is defined in terms of *object -mutation*, so we have to provide *this very particular mutating -operation*, but nothing else. Of course, you are free to mark your -variables ``const`` to completely forbid assignment. - -.. warning:: - - **Assignment is not thread safe**. When a *mutable* variable is - shared across multiple threads, protect access using some other - mechanism. - - For obvious reasons, all other methods, which are ``const``, are - thread-safe. It is safe to share *immutable* state across multiple - threads. - -To ``const`` or not to ``const`` --------------------------------- - -Many C++ programmers, influenced by functional programming, are trying -to escape the evils of mutability by using ``const`` whenever -possible. We also do it ourselves in many of our examples to -reinforce the property of immutability. - -While in general this is a good practice backed up with very good -intentions, it has one caveat: *it disables moveability*. It does so -even when ``std::move()`` is used. This makes sense, since moving from -an object may mutate it, and ``const``, my friends, prevents *all* -mutations. For example: - -.. literalinclude:: ../example/vector/move.cpp - :language: c++ - :start-after: move-bad/start - :end-before: move-bad/end - -One may think that the variable ``v`` is moved into the -``push_back()`` call. This is not the case, because the variable -``v`` is marked ``const``. Of course, one may enable the move by -removing it, as in: - -.. literalinclude:: ../example/vector/move.cpp - :language: c++ - :start-after: move-good/start - :end-before: move-good/end - -So, is it bad style then to use ``const`` as much as possible? I -wouldn't say so and it is advisable when ``std::move()`` is not used. -An alternative style is to not use ``const`` but adopt an `AAA-style -<aaa>`_ (*Almost Always use Auto*). This way, it is easy to look for -mutations by looking for lines that contain ``=`` but no ``auto``. -Remember that when using our immutable containers ``operator=`` is the -only way to mutate a variable. - -.. _aaa: https://herbsutter.com/2013/08/12/gotw-94-solution-aaa-style-almost-always-auto/ - -.. admonition:: Why does ``const`` prevent move semantics? - - For those adventurous into the grainy details C++, here is why. - ``std::move()`` does not move anything, it is just *a cast* from - normal *l-value* references (``T&``) to *r-value* reference - (``T&&``). This is, you pass it a variable, and it returns a - reference to its object disguised as an intermediate result. In - exchange, you promise not to do anything with this variable later - [#f1]_. It is the role of the thing that *receives the moved-from - value* (in the previous example, ``push_back``) to actually do - anything interesting with it --- for example, steal its contents - ๐. - - So if you pass a ``T&`` to ``std::move()`` you get a ``T&&`` and, - unsurprisingly, if you pass a ``const T&`` you get a ``const T&&``. - But the receivers of the moved-from value (like constructors or our - ``push_back()``) maybe be moved-into because they provide an - overload that expects ``T&&`` --- without the ``const``! Since a - ``const T&&`` can not be converted into a ``T&&``, the compiler - looks up for you another viable overload, and most often finds a - copy constructor or something alike that expects a ``const T&`` or - just ``T``, to which a ``const T&&`` can be converted. The code - compiles and works correctly, but it is less efficient than we - expected. Our call to ``std::move()`` was fruitless. - - .. [#f1] For the sake of completeness: it is actually allowed to do stuff - with the variable *after another value is assigned to it*. - -.. _move-semantics: - -Leveraging move semantics -------------------------- - -When using :ref:`reference counting<rc>` (which is the default) -mutating operations can often be faster when operating on *r-value -references* (temporaries and moved-from values). Note that this -removes *persistence*, since one can not access the moved-from value -anymore! However, this may be a good idea when doing a chain of -operations where the intermediate values are not important to us. - -For example, let's say we want to write a function that inserts all -integers in the range :math:`[first, last)` into an immutable vector. -From the point of view of the caller of the function, this function is -a *transaction*. Whatever intermediate vectors are generated inside -of it can be discarded since the caller can only see the initial -vector (the one passed in as argument) and the vector with *all* the -elements. We may write such function like this: - -.. literalinclude:: ../example/vector/iota-move.cpp - :language: c++ - :start-after: myiota/start - :end-before: myiota/end - -The intermediate values are *moved* into the next ``push_back()`` -call. They are going to be discarded anyways, this little -``std::move`` just makes the whole thing faster, letting ``push_back`` -mutate part of the internal data structure in place when possible. - -If you don't like this syntax, :doc:`transients<transients>` may be -used to obtain similar performance benefits. - -.. admonition:: Assigment guarantees - - From the language point of view, the only requirement on moved from - values is that they should still be destructible. We provide the - following two additional guarantees: - - - **It is valid to assign to a moved-from variable**. The variable - gets the assigned value and becomes usable again. This is the - behaviour of standard types. - - - **It is valid to assign a moved-from variable to itself**. For - most standard types this is *undefined behaviour*. However, for our - immutable containers types, expressions of the form ``v = - std::move(v)`` are well-defined. - -Recursive types ---------------- - -Most containers will fail to be instantiated with a type of unknown -size, this is, an *incomplete type*. This prevents using them for -building recursive types. The following code fails to compile: - -.. code-block:: c++ - - struct my_type - { - int data; - immer::vector<my_type> children; - }; - -However, we can easily workaround this by using an ``immer::box`` to wrap -the elements in the vector, as in: - -.. code-block:: c++ - - struct my_type - { - int data; - immer::vector<immer::box<my_type>> children; - }; - -.. admonition:: Standard containers and incomplete types - - While the first example might seem to compile when using some - implementations of ``std::vector`` instead of ``immer::vector``, such - use is actually forbidden by the standard: - - **17.6.4.8** *Other functions (...)* 2. the effects are undefined in - the following cases: (...) In particular---if an incomplete type (3.9) - is used as a template argument when instantiating a template - component, unless specifically allowed for that component. - -.. _batch-update: -Efficient batch manipulations ------------------------------ - -Sometimes you may write a function that needs to do multiple changes -to a container. Like most code you write with this library, this -function is *pure*: it takes one container value in, and produces a -new container value out, no side-effects. - -Let's say we want to write a function that inserts all integers in the -range :math:`[first, last)` into an immutable vector: - -.. literalinclude:: ../example/vector/iota-slow.cpp - :language: c++ - :start-after: include:myiota/start - :end-before: include:myiota/end - -This function works as expected, but it is slower than necessary. -On every loop iteration, a new value is produced, just to be -forgotten in the next iteration. - -Instead, we can grab a mutable view on the value, a :ref:`transient`. -Then, we manipulate it *in-place*. When we are done with it, we -extract back an immutable value from it. The code now looks like -this: - -.. _iota-transient: - -.. literalinclude:: ../example/vector/iota-transient.cpp - :language: c++ - :start-after: include:myiota/start - :end-before: include:myiota/end - -Both conversions are :math:`O(1)`. Note that calling ``transient()`` -does not break the immutability of the variable it is called on. The -new mutable object will adopt its contents, but when a mutation is -performed, it will copy the data necessary using *copy on write*. -Subsequent manipulations may hit parts that have already been copied, -and these changes are done in-place. Because of this, it does not -make sense to use transients to do only one change. - -.. tip:: - - Note that :ref:`move semantics<move-semantics>` can be used instead to - support a similar use-case.
