High-order functions such as ``map``, ``filter``, ``reduce``, -``zip``, etc., make it easy to **write simple and efficient functional code**. - -Let's see an example: - - > -- Functional style - > require "fun" () - > -- calculate sum(x for x^2 in 1..n) - > n = 100 - > print(reduce(operator.add, 0, map(function(x) return x^2 end, range(n)))) - 328350 - - > -- Object-oriented style - > local fun = require "fun" - > -- calculate sum(x for x^2 in 1..n) - > print(fun.range(n):map(function(x) return x^2 end):reduce(operator.add, 0)) - 328350 - -**Lua Fun** takes full advantage of the innovative **tracing JIT compiler** -to achieve transcendental performance on nested functional expressions. -Functional compositions and high-order functions can be translated into -**efficient machine code**. Can you believe it? Just try to run the example -above with ``luajit -jdump`` and see what happens: - - -- skip some initilization code -- - ->LOOP: - 0bcaffd0 movaps xmm5, xmm7 - 0bcaffd3 movaps xmm7, xmm1 - 0bcaffd6 addsd xmm7, xmm5 - 0bcaffda ucomisd xmm7, xmm0 - 0bcaffde jnb 0x0bca0024 ->5 - 0bcaffe4 movaps xmm5, xmm7 - 0bcaffe7 mulsd xmm5, xmm5 - 0bcaffeb addsd xmm6, xmm5 - 0bcaffef jmp 0x0bcaffd0 ->LOOP - ---- TRACE 1 stop -> loop - -The functional chain above was translated by LuaJIT to (!) **one machine loop** -containing just 10 CPU assembly instructions without CALL. Unbelievable! - -Readable? Efficient? Can your Python/Ruby/V8 do better? - -Status ------- - -**Lua Fun** is in an early alpha stage. The library fully [documented] -[Documentation] and covered with unit tests. - -[] -(https://travis-ci.org/luafun/luafun) - -LuaJIT 2.1 alpha is recommended. The library designed in mind of fact that -[LuaJIT traces tail-, up- and down-recursion][LuaJIT-Recursion] and has a lot of -[byte code optimizations][LuaJIT-Optimizations]. Lua 5.1-5.3 are also -supported. - -This is **master** (development) branch. API may be changed without any special -notice. Please use **stable** branch for your production deployments. -If you still want to use **master**, please don't forget to grep `git log` -for *Incompatible API changes* message. Thanks! - -Please check out [documentation][Documentation] for more information. - -Misc ----- - -**Lua Fun** is distributed under the [MIT/X11 License] - -(same as Lua and LuaJIT). - -The library was written to use with [Tarantool] - an efficient in-memory -store and an asynchronous Lua application server. - -See Also --------- - -* [Documentation] -* [RockSpec] -* [RPM/DEB packages](https://packagecloud.io/rtsisyk/master) -* lua-l@lists.lua.org -* luajit@freelists.org -* roman@tsisyk.com - - [Lua]: http://www.lua.org/ - [LuaJIT]: http://luajit.org/luajit.html - [LuaJIT-Recursion]: http://lambda-the-ultimate.org/node/3851#comment-57679 - [LuaJIT-Optimizations]: http://wiki.luajit.org/Optimizations - [MIT/X11 License]: http://opensource.org/licenses/MIT - [Tarantool]: http://github.com/tarantool/tarantool - [Getting Started]: https://luafun.github.io/getting_started.html - [Documentation]: http://luafun.github.io/ - [RockSpec]: https://raw.github.com/luafun/luafun/master/fun-scm-1.rockspec - -Please **"Star"** the project on GitHub to help it to survive!
