djfdyuruiry / lualinq

Lightweight LINQ like library for Lua.

lualinq

Lightweight library which allows functional querying and transformation of lua arrays and objects.

The syntax is very similar to the C# linq or Java 8 streams libraries, which are similar in syntax to SQL. It’s released with a BSD 3 clause license.

Install

There is a LuaRocks package for this library: https://luarocks.org/modules/djfdyuruiry/lualinq

To install, install luarocks, and then run:

luarocks install lualinq

Usage

local lualinq = require "lualinq"
local from = lualinq.from

local count = from({1,2,3,4,5}).
  where(function(v) return v > 2; end).
  count()

-- prints '3'
print(count)

Full documentation on all available functions can be found here

I forked this library to add Lua 5.3 support and update the luarocks module I maintain for this library. Originally authored by xanathar

Credit goes to buckle2000 for cleaning up the the original version of lualinq, see their work here
