I want to add table 'mm' to table 'fmenu.pages' but it doesnt work at all. Error: attempt to index a nil value (field 'main2'). Its about last line. Code:
local fmenu = {
selected_button = 0,
menu = {
font = 1,
},
pages = {
["main"] = {
name = "name",
id = 1,
btns = {
{name = "name I", id = 1}
}
}
}
}
local mm = {
["main2"] = {
name = "name2",
id = 2,
btns = {
{name = "name I", id = 1},
{name = "name II", id = 2}
}
}
}
table.insert(fmenu.pages, mm)
print(fmenu.pages["main2"].name)
How about using table.merge from lua-stdlib?
local table = require"std.table"
local fmenu = {
selected_button = 0,
menu = {
font = 1,
},
pages = {
["main"] = {
name = "name",
id = 1,
btns = {
{name = "name I", id = 1}
}
}
}
}
local mm = {
["main2"] = {
name = "name2",
id = 2,
btns = {
{name = "name I", id = 1},
{name = "name II", id = 2}
}
}
}
table.merge(fmenu.pages, mm)
print(fmenu.pages["main2"].name)

Unfortunately, sorting tables in lua still remains difficult for me. Who can help me with the following question:
I would like to sort the table below by pluNumber:
Original tabel:
[3] = {
[1] = {
['article'] = {
['pluNumber'] = '204',
['name'] = 'Cola Zero'
}
},
[2] = {
['article'] = {
['pluNumber'] = '202',
['name'] = 'Sinas'
}
},
[3] = {
['article'] = {
['pluNumber'] = '203',
['name'] = '7-up'
}
},
[4] = {
['article'] = {
['pluNumber'] = '201',
['name'] = 'Cola'
}
}
}
New table:
[3] = {
[1] = {
['article'] = {
['pluNumber'] = '201',
['name'] = 'Cola'
}
},
[2] = {
['article'] = {
['pluNumber'] = '202',
['name'] = 'Sinas'
}
},
[3] = {
['article'] = {
['pluNumber'] = '203',
['name'] = '7-up'
}
},
[4] = {
['article'] = {
['pluNumber'] = '204',
['name'] = 'Cola Zero'
}
}
}
Where do I begin? I didn't succeed with a normal table.sort
Please help
You need to provide a function that tells Lua which of two table elements comes first.
table.sort(yourTable, function (a, b)
return a.article.pluNumber < b.article.pluNumber end
Or
table.sort(yourTable, function (a, b)
return a.article.pluNumber > b.article.pluNumber end
for decending order. This is explained in the Lua reference manual.

I need to do web scraping for a website which has allowed robot access. Below is the robot.txt file's content.

How can I achieve this web scraping?
The following code is for an escape menu in a garrys mod server. It's written in lua. I have no idea what the problem could be and I've been working at it for a very long time. There is absolutely no error returned. Here's the full thing:
local buttonList = {
{
name = "Continue",
callback = function(panel)
panel:Remove();
Atomic.pauseUI = nil;
end
},
{
name = "Menu",
callback = function(panel)
panel:Remove();
gui.ActivateGameUI();
Atomic.showDefaultMenu = true;
Atomic.delayCheck = true;
end
},
--[[
{
name = "Settings",
callback = function(panel)
// panel:Remove();
end
},
--]]
{
name = "Rules",
callback = function(panel)
gui.OpenURL("https://steamcommunity.com/linkfilter/?url=https://facepunch.com")
end;
},
{
name = "Disconnect",
callback = function(panel)
RunConsoleCommand("disconnect");
end
}
};
I need to filter this NSMutableDictionary on key value based where item_type= bad
i tried but not working
NSPredicate *pred=[NSPredicate predicateWithFormat:#"(item_type == %#)", #"Good"];
NSArray *resultArray = [[dummyDictionary allValues] filteredArrayUsingPredicate:pred];
NSLog(#"resultArray:%#",resultArray);
{
“Cat1” = (
{
"image_item" = “a”;
"item_type" = “Good”;
}
);
Cat2 = (
{
"image_item" = “b”;
"item_type" = Good;
},
{
"image_item" = “c”;
"item_type" = Bad;
},
);
Cat3 = (
{
"image_item" = “d”;
"item_type" = Good;
},
{
"image_item" = “e”;
"item_type" = Bad;
},
);
}
And need such output NSMutableDictionary
{
“Cat1” = (
);
Cat2 = (
{
"image_item" = “c”;
"item_type" = Bad;
},
);
Cat3 = (
{
"image_item" = “e”;
"item_type" = Bad;
},
);
}
NOTE: dummyDictionary is value i get from .plist
I have searched the forums and stack overflow for it and still can't understand how to do this. I don't know how to parse the results for a specific album in the results. I want to get the photos for the profile pictures album. So far I got:
func retrieveFBProfileAlbum(){
print("RetrievingFBProfileAlbum")
FBSDKGraphRequest(graphPath: "me/albums/", parameters: ["fields": "name, photos"]).startWithCompletionHandler({ (connection, result, error) -> Void in
if (error == nil){
// let results = result as! NSDictionary
// print(result)
if let array: AnyObject = result["data"] {
for resultDict in array as! [AnyObject] {
if let resultDict = resultDict as? [String : AnyObject] {
for (name, value) in resultDict{
print("NAME A: \(name), VALUE A \(value)")
}
}
}
}
}else{
print(error.localizedDescription)
}
})
}
I got the results as id, name, photos, id, name, photos. Not sure what to do with this :( I can print only the names of the albums but I don't know how to get the pics of Profile Pictures album:/
Please help as Ive spent many hours on this and still can't get it.
