오늘 알게 된것.

Lua 설치.

Visual Studio Code 연동

 

lua의 데이터 타입과, Redis의 데이터 타입간 매칭이 있음.

 

Redis to Lua conversion table.

• Redis integer reply -> Lua number
• Redis bulk reply -> Lua string
• Redis multi bulk reply -> Lua table (may have other Redis data types nested)
• Redis status reply -> Lua table with a single ok field containing the status
• Redis error reply -> Lua table with a single err field containing the error
• Redis Nil bulk reply and Nil multi bulk reply -> Lua false boolean type

Lua to Redis conversion table.

• Lua number -> Redis integer reply (the number is converted into an integer)
• Lua string -> Redis bulk reply
• Lua table (array) -> Redis multi bulk reply (truncated to the first nil inside the Lua array if any)
• Lua table with a single ok field -> Redis status reply
• Lua table with a single err field -> Redis error reply
• Lua boolean false -> Redis Nil bulk reply.

 

Return 타입도 여기 대응대로 매칭.

lua의 string split은 string.gmatch를 이용해서 regular expression을 이용해서 가능.
