计算长度
function table_leng(t)
local leng=0
for k, v in pairs(t) do
leng=leng+1
end
return leng;
end
function trim(s)
return (string.gsub(s, "^%s*(.-)%s*$", "%1"))
end
打印表
function print_r ( t )
local print_r_cache={}
local function sub_print_r(t,indent)
if (print_r_cache[tostring(t)]) then
print(indent.."*"..tostring(t))
else
print_r_cache[tostring(t)]=true
if (type(t)=="table") then
for pos,val in pairs(t) do
if (type(val)=="table") then
print(indent.."["..pos.."] => "..tostring(t).." {")
sub_print_r(val,indent..string.rep(" ",string.len(pos)+8))
print(indent..string.rep(" ",string.len(pos)+6).."}")
elseif (type(val)=="string") then
print(indent.."["..pos..'] => "'..val..'"')
else
print(indent.."["..pos.."] => "..tostring(val))
end
end
else
print(indent..tostring(t))
end
end
end
if (type(t)=="table") then
print(tostring(t).." {")
sub_print_r(t," ")
print("}")
else
sub_print_r(t," ")
end
print()
end
去重复
function table_unique(t)
local check = {};
local n = {};
for key , value in pairs(t) do
if not check[value] then
n[key] = value
check[value] = value
end
end
return n
end
