我有一个外部lua表,其结构如下:
sgeT = {
[2535047] = {
{
["account"] = "TG-MCB110105",
["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
["execEpoch"] = 1305825864,
["execModify"] = "Thu May 19 12:24:24 2011",
["execType"] = "user:binary",
["jobID"] = "2535047",
["numCores"] = "128",
["numNodes"] = "8",
pkgT = {
},
["runTime"] = "65125",
["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
sizeT = {
["bss"] = "104552",
["data"] = "192168",
["text"] = "10650813",
},
["startEpoch"] = "1335843433",
["startTime"] = "Mon Apr 30 22:37:13 2012",
["user"] = "guo",
},
},
[2535094] = {
{
["account"] = "TG-MCB110105",
["exec"] = "/share/home/00288/tg455591/NAMD_2.8b3/NAMD_2.8b3_Linux-x86_64-MVAPICH-Intel-Ranger/namd2",
["execEpoch"] = 1305825864,
["execModify"] = "Thu May 19 12:24:24 2011",
["execType"] = "user:binary",
["jobID"] = "2535094",
["numCores"] = "128",
["numNodes"] = "8",
pkgT = {
},
["runTime"] = "81635",
["sha1"] = "e157dd510a7be4d775d6ceb271373ea24e7f9559",
sizeT = {
["bss"] = "104552",
["data"] = "192168",
["text"] = "10650813",
},
["startEpoch"] = "1335823028",
["startTime"] = "Mon Apr 30 16:57:08 2012",
["user"] = "guo",
},
},
我正在尝试使用以下lua脚本来打印exec键/值对,如下所示:
function DeepPrint (e)
if type(e) == "table" then
for k,v in pairs(e) do
if k == "exec" then
print(k)
DeepPrint(v)
end
end
else
print(e)
end
end
FileStr = "lariatData-sgeT-2012-05-01_2.lua"
Hnd, ErrStr = io.open(FileStr, "r")
if Hnd then
dofile(FileStr)
for Str in Hnd:lines() do
DeepPrint(sgeT)
end
Hnd.close()
else
print(ErrStr, "\n")
end
理想情况下,我想打印数字索引和exec值,例如:
2535047 execVal
但是,运行代码时没有任何返回。最初数字索引没有用方括号括起来,但我添加了它们以便能够读取文件。但是,鉴于它们不是顺序的,我不能像数组那样循环遍历它们,但我相信这些数字索引可能是我问题的根源。我不确定我的代码有什么问题,但它什么也没有返回。任何人都可以推荐我如何修复代码,以便我可以获得适当的键和值返回?在此先感谢!!!

由于您的表格具有固定的结构,因此您只需使用语法糖sgeT[key1][key2]
即可访问exec
键。
for i, v in pairs( sgeT ) do
print( i, v[1].exec )
end
以下是一个工作示例:http://eval.in/16460

您正在迭代文件中的行,但您已经处理并加载了该文件(作为Lua块),因此不再需要它。就这样做:
dofile(FileStr)
DeepPrint(sgeT)
主要问题是你只能递归调用DeepPrint
那些值为exec
的键,但是第一级的键都没有(所以没有打印,因为你没有去超越第一级)。您可能需要在致电if
之前关闭DeepPrint
:
function DeepPrint (e)
if type(e) == "table" then
for k,v in pairs(e) do
if k == "exec" then
print(k)
end
DeepPrint(v)
end
else
print(e)
end
end
