python 表 转 lua table 字符串

python 表 转 lua table 字符串

• 0. 特性:
• 1. 直接上代码
• 2. 用法
• 3. 实例
• 3.1 代码
• 3.2 输出

前言: 有个给cocos2dx-lua 写工具的需求, 要求导出lua table文件,找不到现成合用的库,于是自己写了一套

0. 特性:

1. list dict tuple 可混合使用 统一转换成 lua的table
2. 带有合理的缩进
3. 引用成环 会报错
4. key只能为字符串或数字

1. 直接上代码

class LuaMaker:
"""
lua 处理器
"""

@staticmethod
def makeLuaTable(table):
"""
table 转换为 lua table 字符串
"""
_tableMask = {}
_keyMask = {}
def analysisTable(_table, _indent, _parent):
if isinstance(_table, tuple):
_table = list(_table)
if isinstance(_table, list):
_table = dict(zip(range(1, len(_table) + 1), _table))
if isinstance(_table, dict):

if _tableMask.has_key(id(_table)):
print("error: LuaMaker.makeLuaTable() 成环: this = "+ _parent + "  oldP = " + _tableMask[id(_table)])
return

_tableMask[id(_table)] = _parent
cell = []
thisIndent = _indent + "    "
for k in _table:
if not (isinstance(k, str) or isinstance(k, int) or isinstance(k, float)):
print("error: LuaMaker.makeLuaTable() key类型错误: parent = "+ _parent + "  key = " + k)
return
key = isinstance(k, int) and "[" + str(k) + "]" or "[\"" + str(k) + "\"]"
if _keyMask.has_key(_parent + key):
print("error: LuaMaker.makeLuaTable() 重复key: key = "+ _parent + key)
return
_keyMask[_parent + key] = True

var = None
v = _table[k]
if isinstance(v, str):
var = "\"" + v + "\""
elif isinstance(v, bool):
var = v and "true" or "false"
elif isinstance(v, int) or isinstance(v, float):
var = str(v)
else:
var = analysisTable(v, thisIndent, _parent + key)
cell.append(thisIndent + key + " = " + var)
lineJoin = ",\n"
return "{\n" + lineJoin.join(cell) + "\n" + _indent +"}"

else:
print("error: LuaMaker.makeLuaTable() table类型错误: "+ _parent)

return analysisTable(table, "", "root")

2. 用法

strLuaTable = LuaMaker.makeLuaTable(tableTTT)

3. 实例

3.1 代码

tableTTT = {
1:456,
2.3:"2dsfaads",
"ks":("fsda","eqwe"),
"list":[13,"fdsa"],
"d":{"a":456}
}
ttt = LuaMaker.makeLuaTable(tableTTT)
print(ttt)

3.2 输出

{
["ks"] = {
[1] = "fsda",
[2] = "eqwe"
},
[1] = 456,
["list"] = {
[1] = 13,
[2] = "fdsa"
},
["d"] = {
["a"] = 456
},
["2.3"] = "2dsfaads"
}
