Apache OpenDAL™ Lua Binding (WIP)

Note: This binding has its own independent version number, which may differ from the Rust core version. When checking for updates or compatibility, always refer to this binding's version rather than the core version.

Example

local opendal = require("opendal")

local op, err = opendal.operator.new("fs",{root="/tmp"})
if err ~= nil then
    print(err)
    return
end
op:write("test.txt","hello world")
print("read: ", op:read("test.txt"))

Lua version

You have to enable one of the features: lua54, lua53, lua52, lua51, luajit(52) or luau in Cargo.toml, according to the chosen Lua version. Default Lua version is 5.2.

Build from source

  1. Build OpenDAL Lua Interface
$ cd bindings/lua
$ cargo build --package opendal-lua --release
  1. Install opendal Lua library
# copy to lua share library directory
# default lua5.2 share library directory is /usr/lib/lua/5.2
$ cp ../../target/release/libopendal_lua.so /usr/lib/lua/5.2/opendal.so

Install from LuaRocks

$ luarocks make

Usage

$ lua5.2 example/fs.lua
read:   hello world
