That's OK, I am sure you must have been very busy. Happens.

We investigated getting data from an API or bot, but after hours of research, we realized that we don't need/want that much data - we actually just want user count. So, my friend just hard-coded the whole widget in less than 50 lines (without listing users/avatars/roles). I find his code much easier to understand that the code used on Discord.js. Thank you for all the help.

Here is his code: https://nonograms-katana.fandom.com/wiki/MediaWiki:NKDiscord.js

A comparison between the 2 version (no avatars/users and hard-coded channels):

@KockaAdmiralac

It would appear that the Discord data that is passed to the script has only limited parameters (this data: https://discordapp.com/api/guilds/1238437678974898196/widget.json ). There is no other way expend the scope of this to get more data from a server, is it? This data only includes voice channels.

I've read the Discord API "getting started" documentation, but I couldn't figure out how to implement it on the wiki. Can you give me an advice?

Thank you for your answer.

I was more leaning towards the DiscordIntegrator, because it has less lines of code. xD

Why does it say it's "Experimental"? Is it because of the "roles-*" variable?

DiscordIntegrator: custom channels

I like the Discord widget and how easy it was to implement it. Unfortunately, the widget does not quite display what we would like it to display.

Current version displays:

Discord logo
Count of members online
Voice channels
List of members online
Link to join Discord server

What we would like to display instead:

Discord logo
Count of members online
Custom channels (e.g. #wiki, #news, #support, etc.) - we don't really use voice channels, because we are a bunch of shy, but nice people
Link to join Discord server

I know that changing the current version for DiscordIntegrator will probably not be applicable for everyone, that's why I think I would have to make my own version of it. If I understand correctly, I would have to copy the JS code from this DiscordIntegrator, paste it into the Common.js and modify it. My knowledge of JS is limited to making simple calculators on our wiki. I would have to find documentation of Discord API (probably this one?) and just add the custom channels. Then remove the code that is not needed. I have looked and found that there is Discord.js and DiscordChat.js, but none of these have the functionality that I am looking for (also I can't get DiscordChat to show on our wiki). Is it even possible to add custom channels to the widget? Does anyone have an info on where to find the information I am looking for or a link to a source?

Thank you for the work you do around here.

PS: If anyone has a code that I can use, I am more than happy to use it. :)

Ah, ok. You always help me. Thank you, Nam.

Sorry for not linking the test page. Here it is.

I thought line break were not needed. I thought they were more of a stylistic recommendation for easier reading. This leads me to another question: Why did this code then work? After I removed line breaks it was working just fine (but I didn't Purge the page, if that matters?). Maxx wrote this code (he's a pro) and I don't understand much of if, but it did have a return "table" at the end.

Also one other question: how does this affect speed and memory, if I generate the whole table? I know Lua has some limitations.

Lua: generating a table

I am trying to generate a table in Lua. When I pass the table with the "return" and do an "#invoke" on a page, it shows empty. I know that I can make a template with a bunch of "{{{variables}}}" and pass the variables with Lua to the template, but I actually don't know how to do that either (how to pass variables). :(

If it'd be done with a template, I don't think I could make certain columns not show if they'd be empty. I want a "dynamic" table (I don't know if that's the right word for it). Although I would have to make a template anyway, because I don't like using "#invoke" on pages.

I don't know how efficient it is for passing a whole table with Lua. It'd be probably faster if I'd use your fancy Table-generator module, but I don't like using code I don't fully understand. I also couldn't find what the "return" can/can't return or how to generate a table on this wiki. :(

This is how far I've gotten: https://nonograms-katana.fandom.com/wiki/Module:Dungeon-enemies

Well, at least it doesn't show any errors anymore. :)

Any help is greatly appreciated.

This is very well explained, thank you very much.

Thank you very much Nam. I have managed to figure out the right syntax by looking the code from other modules. Here is the final code:

local p = {}

function p.item(frame)
	local i = frame.args[1]
	local px = frame.args[2]
	local items = {
	    coin = { name = 'Coin', link = 'Coin' },
	    ruby = { name = 'Ruby', link = 'Ruby' },
	    beam = { name = 'Wooden beam', link = 'Wooden beam' },
	    bomb = { name = 'Bomb', link = 'Bomb (Horoku)' }
	}

	if items[i] then
		return '[[File:' .. items[i].name .. '.png|' .. px .. 'px|link=Items#' .. items[i].link .. ']]'
	end
end
 
return p

Although I still need to add the rest of the items. The code on the template:

<onlyinclude>{{#invoke:Item|item|{{{1|}}}|{{{2|40}}}}}</onlyinclude>

Thank you for explaining the code. I still don't understand why

if items[i] then block end

Would work and how how these "directories" work? Aren't you supposed to loop through the whole directory to find the right item? I also don't understand why don't my for loops work? My for loop example:

local i = 'ruby'
local n
local items2 = {'coin','ruby','beam','bomb'}
local items3 = {'one','two','three','four'}
	
for k,j in ipairs(items2) do
	if i == items2[j] then
		n = j
		break
	end
end
return items3[n]

This code is supposed to loop through items2, find the right word (in this case 'ruby'), save the index to 'n' and return the value stored in items3 with the same index. I just couldn't make it work and I have tried many times with some modifications. I am trying to figure out loops for a future project, whatever that might be.

Thanks to you too, BryghtShadow. Although I was looking for a Lua answer (because I am trying to learn it), you have provided me with a great (simpler) alternative, if I couldn't manage to make Lua work.

Trying to learn Lua

Hello. I am trying to learn Lua on an example. I am trying to create a Lua script that displays an image of an item. I have made 50+ templates (example: Template:Coin) that display the wanted image, but maintaining it might be too much work. I thought I could compile all those templates to just one template with an array and for loop. The prefered syntax on the page would be:

{{I|coin|px}}

Where the 'I' would be the template, 'coin' would be the variable that goes into the template and 'px' would be an optional variable defining the width of the image. Here is the page I am testing on.

So the template would be 'Template:I'. The code on the template would probably be similar to this:

<onlyinclude>{{#invoke:Item|item|px}}</onlyinclude>

The Lua code gives me a really hard time. This is what I got so far:

local p = {}
local px = 40 --width of the image
local i = 'ruby' --where the item call should be saved {{I|i}}
local n = 1 --number of the index in array
local itemCall = {'coin', 'ruby', 'beam', 'bomb'}
local itemName = {'Coin', 'Ruby', 'Wooden beam', 'Bomb'}
local itemLink = {'Coin', 'Ruby', 'Wooden beam', 'Bomb (Horoku)'}

function p.item(itemCall,itemName,itemLink)
	for k,j in ipairs(itemCall) do
		if i == itemCall[j] then
			n = j
		end
	end
	return '[[File:' + itemName[n] + '.png|' + px + '|link=Items#' + itemLink[n] + ']]'
end
 
return p

The return is probably completely wrong. Also I don't know the difference between 'ipairs' and 'pairs'. Does that 'p' have to be in the code at all? How do you transfer the variable you put into the table on a page to the template and then into the Lua code (this is the most important thing)? Does #itemCall not return the length of the array/table? What does the 'local' thing do (aren't all variables local)?

I have looked through Lua reference manual and some of the modules on this wiki, but I can't figure it out. When I have discover templates I was really amazed at their implications and sad that I haven't discovered them sooner. But when I read in your frequently asked questions that Lua can do everything templates can do and more, I decided to learn Lua instead. Lua really sounds like a better version of templates, I just need to learn it first.

Thank you for fixing that, that really helped.

At first look it didn't look like JS and that has confused me. I was expecting <this>and<that>.

I have finally made the base for my calculator. It took me a while to figure out that I can replace the "mw-content-text" with the id of the element I wanted (so I can place the input box anywhere on the page I wanted). Maybe it would be a good idea to add that to the description as well.

Thank you very much.

When I paste the function part of my code in the Console it works, if I set the "level" variable to a specific number. Although it works, it doesn't really help me if I can't get the input of the user.

Thank you for correcting that, I got that code from your "Cookbook". I was trying to implement a switch, like the one described on Advanced CSS and JS page. I thought if was the same.

I don't know what that "textParpendChild" function does either. I copied that exact code from your Cookbook. Maybe look into that?

I looked into the "inputbox" already. It sadly has only 3 options: create a page, leave a comment or search the wiki. None of these 3 options work for this purpose.

Thank for responding and trying to help, but I think I need more help, sorry.

PS: I corrected the switch and deleted that function, which I don't know what it does. Sadly it's still not working.

I can't figure out the basics

Hello.

I want to make a simple table that would change the values of cells according to what the user writes in the input field (and clicks the "Calculate" button). So I wrote the code in Notepad and tested it in Chrome. It works great. Then I wrote to Fandom support to enable JavaScript on our wiki. They have enabled it and suggested to check this wiki out, so I did. I had no idea (I still don't) how to make this little program work on our wiki. I decided to start with simple examples (building blocks) and work from there. I have copy-pasted the "Input box" code from the "Cookbook" into our Common.js page and changed the 'Example_Page' with, the page I wanted, 'Levelling'. I have refreshed the page to bypass the cache (ctrl + shift + R) multiple times and the input box was nowhere to be seen on the page. I entered Test mode and also exited it to no avail. In the end I have decided to exit Test mode and submit the code for review. The code got approved today, but I still can't see the input box. Do I have to do something on the Levelling page? What if I don't want that the input box is at the bottom of the page? Is there a tutorial for this?

The code I want to implement: https://github.com/TheCrossblade/Simple_update_table_wiki/blob/main/the%20code

The page I want to implement it on: https://nonograms-katana.fandom.com/wiki/Levelling

Any help would be greatly appreciated.

PS: Also the page was moved from "Leveling", if that would be an issue.
