- linux: 准备好lua依赖库并放到指定位置，执行make -f lsmdb.mak
# 用法
```lua
-- smdb_test.lua
require("lsmdb")
local log_debug = logger.debug
local jsoncodec = json.jsoncodec
local driver = smdb.create()
local jcodec = jsoncodec()
driver.set_codec(jcodec)
local ok = driver.open("./smdb/xxx.db")
log_debug("open: {}", ok)
local a = driver.put("abc1", {a=123})
local b = driver.put("abc2", "234")
local c = driver.put("abc3", "335")
local d = driver.put("abc4", "436")
local e = driver.put("abc5", "536")
log_debug("put: {}-{}-{}-{}-{}", a, b, c, d, e)
for i = 1, 6 do
local key = "abc" .. i
local da = driver.get(key)
log_debug("get-{}: {}", key, da)
end
local k, v = driver.first()
while v do
log_debug("cursor: {}={}", k, v)
k, v = driver.next()
end
b = driver.del("abc2")
a = driver.del("abc5")
c = driver.put("abc3", "4335")
log_debug("del: {}-{}-{}", a, b, c)
for i = 1, 6 do
local key = "abc" .. i
local da = driver.get(key)
log_debug("del_get-{}: {}", key, da)
end
