Apache OpenDAL™ Lua Binding (WIP)

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.

# 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
