    HelpCenter - A Flat and HTTP Helpfile/Topic Server:
    Version: 1.78

    Description: **COLOUR CODES have CHANGED! See below...**

    This plugin allows you to serve any number of textfiles (and/or web-based texts) as help topics, using the /help command. The help files are placed in the HelpCenter/ folder, and their existence determines their availability within the game. Since the plugin reads the files each time it is invoked, any changes to the textfiles will be reflected immediately in-game. Note that the filenames must contain only characters which are enterable into the Minecraft client. It can also fetch helpfiles from a web server (the files must be in text/plain format, it will not strip out HTML tags or any weird characters, or do any unescaping() so make sure your help page(s) are returning plain text.)​

    If you create a file called HelpCenter/welcome.txt, it will be displayed to every user upon login. This is handy for displaying a message like "Type /help topics for a list of help topics." and so on..​

    If the file contains a specially crafted URL line (see below) then it will fetch the contents of a web page via the URL and return that to the player instead.​

    If the folder ./HelpCenter doesn't exist, it will be created when you first run the plugin.​

    • Compatible with Craftbukkit running Minecraft 1.3x
    • Word-wrapping for those long lines of text
    • Dynamic: any changes to the helpfiles are reflected immediately to the players.
    • Directory traversal protection (trying "/help ../../../../../../../etc/passwd" will not work)
    • This plugin will support as many helpfiles as you can possibly create.
    • It can fetch web-based helpfiles via HTTP. :)
    • C o l o u r s ! (see codes below)
    • Default helpfile with randomly-chosen help item capability (otherwise will pass-thru the /help command if typed in without any arguments)
    • Helpfile redirection!
    Example help files:

    Spears are long and pointy. They can be used to stab things.
    You can also throw them or use them to roast hot dogs.
    ..will result in this when the player types /help spears:

    Here is an example of the text-wrapping feature. This is the help file I made:
    The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over the lazy dogs. The quick brown fox jumped over the lazy dogs.
    ..and here is the line-wrapping (it ended up being split into four separate lines):

    for web-based helpfiles, the format is a single line in the text file consisting of
    [URL http://some.site.url.here..]
    e.g.: [URL http://bananas.are.nice] or [URL http://so.are.raspberries].

    If you want to make it so players can use the above example by typing "/help spear" as well, simply create a file called spear.txt and insert this redirection line:
    [HELP spears]
    This way, you only need to update the original spears.txt to make changes to all linked helpfiles.

    Keywords (replaced by values) - If a help file contains any of the blue keywords listed below, they will be replaced by the following values, respectively:

    • %user% - Bukkit - player - The players name
    • %world% - Bukkit - player - The world the player is in
    • %health% - Bukkit - player - The players health value (0 = dead, 20 = full health)
    • %locx% - Bukkit - player - The players location X
    • %locy% - Bukkit - player - The players location Y
    • %locz% - Bukkit - player - The players location Z
    • %iteminhandid% - Bukkit - player - The ID of the item the player has in hand
    • %iteminhand% - Bukkit - player - The item the player has in hand
    • %isop% - Bukkit - player - Is the player an OP - "YES" or "NO"
    • %serveronlinecount% - Bukkit - Number of players currently on server
    • %serverver% - Bukkit - version of the server
    • %groups% - Plugin - Permissions - The list of groups to which the player belongs.
    • %prigroup% - Plugin - Permissions - The first group returned by Permissions to which the player belongs.
    • %helpver% - Plugin - HelpCenter - Version of the plugin
    Colour Codes:

    To use colours, simply add the following codes anywhere in the text file. They will be parsed out and replaced with the proper codes:​

    &0 = black, &8 = black (hi) = dark grey
    &1 = blue (lo), &9 = blue (hi)
    &2 = green (lo), &a = green (hi)
    &3 = cyan (lo), &b = cyan (hi)
    &4 = red (lo), &c = red (hi)
    &5 = magenta (lo), &d = magenta (hi)
    &6 = yellow (lo), &e = yellow (hi)
    &7 = white (lo) = light grey, &f = white (hi)

    Default Helpfile / Random Help Items:
    If you create a file called HelpCenter/HCdefault.txt (case-sensitive) it will display the contents when the player types /help without any parameters. You can also put multiple items, separated by #!HELP (on its own line) and the HelpCenter will randomly select one of the items and display it to the player when they type /help without any parameters. Otherwise, if HCdefault.txt doesn't exist, it will pass-thru the /help command and return the default Minecraft help text.​

    Example HCdefault.txt:

    There are many help topics available. Please be more specific?
    Help me Rhonda!
    Here's a hint: /help topics
    I'm sorry Dave, I can't help you.

    1. Copy the file HelpCenter.jar into your plugins folder.​
    2. Run the plugin at least once to create the HelpCenter/ directory.​
    3. Create your help text files as described above.​

    Download The Plugin (JAR) v1.78 or..​
    Download The Plugin (ZIP) v1.78​

    Source is at Github ^_^​

    Older Versions (Why you'd want them, I don't know..)​

    Please let me know what you think, if there are any issues or if it doesn't play nicely with the other plugins. It should, though. Also, it doesn't use any super-special classes, just the basic ones, so I'm certain this should work with most earlier versions of CraftBukkit. Suggestions are always welcome.

    Great plugin. I'm just starting to explore bukkit and its plethora of available mods and one of the issues I had with many plugins that add commands is that the /help is either missing or not very good. Now it's super easy to make my own!

    I did come across one bug though. For some reason although my welcome.txt file looks like this:
    = Welcome to Minecraft! =
    You are playing on a private server.
    The current world is: Server Mod Test World.
    You can see the list of available commands
    by typing /help.
    The result in-game looks like this:
    = Welcome to Minecraft! =
    You are playing on a private server.
    e current world is: Server Mod Test World.
    You can see the
     list of available commands
    by typing /help.
    Minecraft doesn't use a mono-spaced font, so I understand why the spacing is different (particularly with regards to the = signs lining up) but where are the extra line breaks coming from? Interestingly, if I then do a
    /help welcome
    the welcome message is displayed perfectly. It only seems to happen when I connect. Color codes are carried across these mysterious line breaks though (I removed the colors from my file while trying to debug the error). Any thoughts?

    EDIT: Forgot to mention I'm running HelpCenter 1.5 with CraftBukkit git-Bukkit-0.0.0-493-g8b5496e-b493jnks

    any update yet weasel on getting this fixed?

    I'd like to preface by saying how much I love this addon. It brings real organization to my server, something that I'm sure all server hosts really appreciate.

    However, I'm having a similar issue to the one Matt L is experiencing. The help messages have their sights set on a couple of my server's players. While we all get a kick out of spamming them in unison, I do miss my command lists :( There is no error message associated with it and it began when I updated to craftbukkit 493 and HelpCenter 1.5. If there's anymore information you think you might want please let us know.

    Thanks again for creating and updating this plugin!

    BTW, it doesn't work with build CB440 either... even tried rick-rolling my server back to that and it didn't help :/

    Yep, I am having this issue as well. This is a great Help mod, no others really compare on the simplicity of setup and ease of use.

    Agreed, hope an update comes out soon for this. About half of my server (not regular) players have left already... It is so hard to appease everyone, I swear...
  9. Offline


    Tell me about it! I've stopped trying to cater to people and do things my way. Like minded people stay and the rest...well.

    Just hope this plugin gets updated soon. have to answer SOOO many questions instead of saying read /help some topic.
  10. Same problems here, I definitely love this plugin though!!! Easy setup and allows thorough help coverage (So many plugins) Especially when there are tools like voxelbox to explain along with minecart mania. Definitely diggin it. I would like to know how to initiate a player list, player names, and perhaps call on other information if you can think to implement it soon. Thanks for the hard work Weasel!!

    Sorry for the AWOL moment.. I'm currently rewriting the whole thing so that help tags can be nested if needed.. It's being a bit of a bugger though. I'll try and get a new working version up today :)

    EDIT: ok, it's updated and rewritten, though I didn't change anything in the onCommand function, so please let me know if the weird players glitch is still happening.

    Good to hear it! Really looking forward to it.

    I forgot to mention something important, but it's in the changelog now :)

    HelpCenter folder now moved to plugins/HelpCenter. This should happen automatically. If you have an empty plugins/HelpCenter folder and all your helpfiles are in HelpCenter then simply delete the empty folder plugins/HelpCenter and restart the server and it should move it properly to the new location.

    ..or you can move it manually :)

    First, love this plugin. Easy setup, makes helpfile management easy.

    Have a strange bug. Just upgraded to 1.6 and moved my HelpCenter folder to the plugins folder. Running Craftbukkit build 493.

    Whenever anyone uses any of the /help command it sends the output to the first person who logs in after a reboot. Nothing in the server.log

    Yep, it's still happening weasel :(

    Sometimes the text goes to the next line only about half way accross. does that have anything to do with this plugin? I notice it mostely with the welcome message when I log on, but not when I type /help welcome.
    On a similar note, would it be possable to make text go to the next line on a space rather than in the middle of a word, or is that something we should bug Mojang about? Great plugin though; very... helpfull. Thanks.
  18. Offline


    OK, I'll investigate and fix that today. I'm probably enumerating the player from the sender incorrectly.. :p

    I thought about the line breaks as well, when I first created the plugin. Originally, the solution was to just format your help text files so they display in a nice way, but I definitely do have plans to make the plugin do this for you instead. This will go into the next version. :)

    On an unrelated note, I know that ejhopkins is planning to make a Bukkit port for Wild Grass, but I've already figured it mostly out and plan to release a Bukkit plugin soon which makes grass grow taller and flowers spread to nearby blocks.. Still experimenting though. And it requires a client mod in order to see the grass, but it's super pretty.

    cool, will that also fix the line breaks from being after only a few words in some random lines? This may only happen with the welcome message when logging in, but I'm not sure. I attached a screenshot.

    I'd like to request that if it doesn't find a file with extension .txt, it looks for one with no extension. I hate the .txt extension :​​​​P
    Very nice plugin though.
  26. Offline


    This would be perfect for my server IF (and I don't know whether or not this is the case) it hides the current /help?

    (Our current /help is just like 35 pages of admin commands)

    Does it override the other /help display and ONLY show your .txts?

    Lastly; is it memory intensive in any way?
  27. Offline


    It can override the main help (he has instructions in his post). Also, it's not memory intensive at all. You can even add a message to display when people log in (though the formatting is bugged just for the welcome message, which is a Bukkit issue, not this plugin). :)

    omfg. this looked like a good plugin, but then I tried to use it and for some reason it failed to split my lines on newline.
    decompiled and found this:
    helpData.replace("\r", "");
    are you serious? YOU USED \r AS NEWLINE?
    this makes the mod useless to me. I will fix it and edit it the link here, but come on, seriously? dumbest mistake to break cross-platform I've ever seen.

    EDIT: god I just did the internet version of walking into a wall. that doesn't do what I thought it did at all, and it's obvious too. will edit again in a minute >.<

    EDIT 2: oh, I see what you did there. you deleted \r instead of properly dealing with it (replace("(\n\r|\n[^\r]|[^\n]\r)", "\n") probably, assuming java supports that regex).

    EDIT 3: ([^\r\n]\r\n[^\r\n]|[^\r\n]\n\r[^\r\n]||[^\r\n][\n\r][^\r\n])

    Hello weasel, the colored text thing did not work for me, so I looked into your code.

    In HelpCenter.java on line (about) 455 you wrote something like
    if( wrapData.length == 1 )  {
        sendToPlayer( who, item, null, topic );
        sendToPlayer( who, null, wrapData, topic );
    Why? Because when I remove the if statement and just put sendToPlayer in it:
    sendToPlayer( who, null, wrapData, topic );
    Then the colored text is returned. Did this happen by accident?

    I had put the cColour() wrapper function in the wrong places, but they're in the correct place now with v1.71 :)

    yeah, I basically stripped the carriage returns (just in case) and then worked the split via the newlines.. It's probably redundant and unnecessary, but you never know what kind of CR/LF formatting will be returned by a web server when fetching the help pages via http, which is the entire reasoning behind that.. :)

    Should I replace that part with the regex you provided above? It does seem to be a better approach.


    EDIT by Moderator: merged posts, please use the edit button instead of double posting.

    Assuming it works, that'd be good. I didn't actually test it, but it looks right.
