The plugins worked, people who wrote them knew how to use them, but for anyone new to the plugin it was a terrible ordeal learning how to use it. Most of the times, the plugin authors only wrote what commands the plugin supported, sometimes not even that. Then, there was a call to action to put an end to this, to make documenting the plugins easy and at the same time centralized. Thus, the Info.lua file was born.</p> + + <p>Most plugins have some parts that are the same across all the plugins. These are commands, console commands and their permissions. If a plugin implemented a command, it would practically copy & paste the same code over and over again. So it makes sense to extract only unique information, centralize it and automate all the parts around it. This was another reason for the Info.lua file - it is a central hub of commands, console commands and their permissions.</p> + + <p>Last, but not least, we want to make a plugin repository on the web in the future, a repository that would store plugins, their descriptions, comments. It makes sense that the centralized information can be parsed by the repository automatically, so that advanced things, such as searching for a plugin based on a command, or determining whether two plugins collide command-wise, are possible.</p> + + <p>After this file format has been devised, a tool has been written that allows for an easy generation of the documentation for the plugin in various formats. It outputs the documentation in a format that is perfect for pasting into the forum. It generates documentation in a Markup format to use in README.md on GitHub and similar sites. The clever thing is that you don't need to keep all those formats in sync manually - you edit the Info.lua file and this tool will re-generate the documentation for you.</p> + + <p>So to sum up, the Info.lua file contains the plugins' commands, console commands, their permissions and possibly the overall plugin documentation, in a structured manner that can be parsed by a program, yet is human readable and editable.</p> + + + <hr /> + <a name="Overall"><h2>The overall structure</h2></a> + + <p>The file consist of a declaration of a single Lua table, g_PluginInfo. This table contains all the information, structured, as its members. Each member can be a structure by itself. The entire file is a valid Lua source file, so any tool that syntax-checks Lua source can syntax-check this file. The file is somewhat forward- and backward- compatible, in the sense that it can be extended in any way without breaking.</p> + <p>Here's a skeleton of the file:</p> +<pre class="prettyprint lang-lua"> +g_PluginInfo = +{ + Name = "Example Plugin", + Date = "2014-06-12", + Description = "This is an example plugin that shows how to use the Info.lua file", + + -- The following members will be documented in greater detail later: + AdditionalInfo = {}, + Commands = {}, + ConsoleCommands = {}, + Permissions = {}, +} +</pre> + <p>As you can see, the structure is pretty straightforward. Note that the order of the elements inside the table is not important (Lua property).</p> + + <p>The first few elements are for book-keeping. They declare the plugin's name, the date in ISO-format, representing the version of the plugin, and the description. The idea is that the description sums up what the plugin is all about, within some two or three sentences.</p> + + + <hr /> + <a name="AdditionalInfo"><h2>AdditionalInfo table</h2></a> + + <p>This table is used for more detailed description of the plugin. If there is any non-trivial setup process, dependencies, describe them here. This is where the description should get detailed. Don't worry about using several paragraphs of text here, if it makes the plugin easier to understand.</p> + + <p>The table should have the following layout:</p> +<pre class="prettyprint lang-lua"> +AdditionalInfo = +{ + { + Title = "Chapter 1", + Contents = "Describe one big aspect of the plugin here", + }, + { + Title = "Chapter 2", + Contents = "Describe another big topic", + }, +} +</pre> + <p>The idea here is that the tool that is used to generate the documentation from the Info.lua file will create a linkified table of contents and then each of the information elements' contents. This information should be all that is needed to successfully configure, run and manage the plugin.</p> + + + <hr /> + <a name="Commands"><h2>Commands table</h2></a> + + <p>The commands table lists all the commands that the plugin implements, together with their handler functions, required permissions, help strings and further information. The table supports recursion, which allows plugins to create multi-word commands easily (such as "//schematic load" and "//schematic save"), each having its own separate handler.</p> + + <p>The table uses structure similar to the following:</p> +<pre class="prettyprint lang-lua"> +Commands = +{ + ["/cmd1"] = + { + HelpString = "Performs the first action", + Permission = "firstplugin.cmds.1", + Alias = "/c1", + Handler = HandleCmd1, + ParameterCombinations = + { + { + Params = "x y z", + Help = "Performs the first action at the specified coordinates", + }, + { + Params = "-p", + Help = "Performs the first action at the player's coordinates", + } + }, + }, + ["/cmd2"] = + { + Alias = {"/c2", "//c2" }, + Subcommands = + { + sub1 = -- This declares a "/cmd2 sub1" command + { + HelpString = "Performs the second action's first subcommand", + Permission = "firstplugin.cmds.2.1", + Alias = "1", + Handler = HandleCmd2Sub1, + ParameterCombinations = + { + { + Params = "x y z", + Help = "Performs the second action's first subcommand at the specified coordinates", + }, + { + Params = "-p", + Help = "Performs the second action's first subcommand at the player's coordinates", + } + }, + }, + sub2 = -- Declares a "/cmd2 sub2" command + { + HelpString = "Performs the second action's second subcommand", + Permission = "firstplugin.cmds.2.2", + Handler = HandleCmd2Sub2, + }, + }, + }, +} +</pre> + + <p>Although it may seem overwhelming at first, there is a "method to this madness". Each element of the Commands table defines one command. Most commands start with a slash, so the special Lua syntax for table elements with non-standard names needs to be applied (<code>["/cmd1"] =</code>). The command can either specify subcommands, or a handler function (specifying both is UndefinedBehavior). Subcommands uses the same structure as the entire Commands table, recursively.</p> + + <p>The permission element specifies that the command is only available with the specified permission. Note that the permission for subcommand's parent isn't checked when the subcommand is called. This means that specifying the permission for a command that has subcommands has no effect whatsoever, but is discouraged because we may add processing for that in the future.</p> + + <p>The ParameterCombinations table is used only for generating the documentation, it lists the various combinations of parameters that the command supports. It's worth specifying even if the command supports only one combination, because that combination will get documented this way.</p> + + <p>The Alias member specifies any possible aliases for the command. Each alias is registered separately and if there is a subcommand table, it is applied to all aliases, just as one would expect. You can specify either a single string as the value (if there's only one alias), or a table of strings for multiple aliases. Commands with no aliases do not need to specify this member at all.</p> + + + <hr /> + <a name="ConsoleCommands"><h2>ConsoleCommands table</h2> + + <p>This table serves a purpose similar to that of the Commands table, only these commands are provided for the server console. Therefore, there are no permissions specified for these commands. Since most console commands don't use a leading slash, the command names don't need the special syntax. Also, the handler function doesn't receive the Player parameter.</p> + + <p>Here's an example of a ConsoleCommands table:</p> +<pre class="prettyprint lang-lua"> +ConsoleCommands = +{ + concmd = + { + HelpString = "Performs the console action", + Subcommands = + { + sub1 = + { + HelpString = "Performs the console action's first subcommand", + Handler = HandleConCmdSub1, + ParameterCombinations = + { + { + Params = "x y z", + Help = "Performs the console action's first subcommand at the specified coordinates", + }, + }, + }, + sub2 = + { + HelpString = "Performs the console action's second subcommand", + Handler = HandleConCmdSub2, + }, + }, + }, +} +</pre> + + + <hr /> + <a name="Permissions"><h2>Permissions table</h2></a> + + <p>The purpose of this table is to document permissions that the plugin uses. The documentation generator automatically collects the permissions specified in the Command table; the Permissions table adds a description for these permissions and may declare other permissions that aren't specifically included in the Command table.</p> + +<pre class="prettyprint lang-lua"> +Permissions = +{ + ["firstplugin.cmd.1.1"] = + { + Description = "Allows the players to build high towers using the first action.", + RecommendedGroups = "players", + }, + ["firstplugin.cmd.2.1"] = + { + Description = "Allows the players to kill entities using the second action. Note that this may be misused to kill other players, too.", + RecommendedGroups = "admins, mods", + }, +} +</pre> + + <p>The RecommendedGroup element lists, in plain English, the intended groups for which the permission should be enabled on a typical server. Plugin authors are advised to create reasonable defaults, prefering security to openness, so that admins using these settings blindly don't expose their servers to malicious users.</p> + + + <hr /> + <a name="Using"><h2>Using the file in code</h2></a> + + <p>Just writing the Info.lua file and saving it to the plugin folder is not enough for it to actually be used. Your plugin needs to include the following boilerplate code, preferably in its Initialize() function:</p> +<pre class="prettyprint lang-lua"> +-- Use the InfoReg shared library to process the Info.lua file: +dofile(cPluginManager:GetPluginsPath() .. "/InfoReg.lua") +RegisterPluginInfoCommands() +RegisterPluginInfoConsoleCommands() +</pre> + + <p>Of course, if your plugin doesn't have any console commands, it doesn't need to call the RegisterPluginInfoConsoleCommands() function, and similarly if it doesn't have any in-game commands, it doesn't need to call the RegisterPluginInfoCommands() function.</p> + + + <hr /> + <a name="Examples"><h2>Examples</h2></a> + + <p>There are several plugins that already implement this approach. You can visit them for inspiration and to see what the generated documentation looks like:</p> + <ul> + <li>Gallery plugin: <a href="https://github.com/mc-server/Gallery/blob/master/Info.lua">Info.lua</a>, <a href="http://forum.mc-server.org/showthread.php?tid=1306">Forum</a> documentation</li> + <li>WorldEdit plugin: <a href="https://github.com/mc-server/WorldEdit/blob/master/Info.lua">Info.lua</a>, <a href="http://forum.mc-server.org/showthread.php?tid=870">Forum</a> and <a href="https://github.com/mc-server/WorldEdit">MarkDown</a> documentation</li> + </ul> + + <script> + prettyPrint(); + </script> + </div> + </body> +</html> diff --git a/Server/Plugins/APIDump/LICENSE-prettify.txt b/Server/Plugins/APIDump/LICENSE-prettify.txt new file mode 100644 index 000000000..b7f86df20 --- /dev/null +++ b/Server/Plugins/APIDump/LICENSE-prettify.txt @@ -0,0 +1,191 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

It has the basic features expected of an IDE - you can group files into project, you can edit multiple files in a tabbed editor, the code is syntax-highlighted. Code completion, symbol browsing, and more. It also features a Lua debugger that allows you to debug your Lua code within any application that embeds the Lua runtime or uses Lua as a dynamic-link library (DLL). Although it is written using the multiplatform WxWidgets toolkit, it hasn't yet been ported to any platform other than 32-bit Windows. This unfortunately means that Linux users will not be able to use it. It can be used on 64-bit Windows, but the debugger only works for 32-bit programs.</p> + <p>Here's a screenshot of a default Decoda window with the debugger stepping through the code (scaled down):<br /> + <img src="Static/decoda_workspace.png" /></p> + <p>As you can see, you can set breakpoints in the code, inspect variables' values, view both the Lua and native (C++) call-stacks. Decoda also breaks program execution when a faulty Lua script is executed, providing a detailed error message and pointing you directly to the faulting code. It is even possible to attach a C++ debugger to a process that is being debugged by Decoda, this way you can trap both C++ and Lua errors.</p> + <p>Decoda is open-source, the sources are on GitHub: <a href="https://github.com/unknownworlds/decoda">https://github.com/unknownworlds/decoda</a>. You can download a compiled binary from the creators' site, <a href="http://unknownworlds.com/decoda/">http://unknownworlds.com/decoda/</a>. + + <h2><img src="Static/decoda_logo.png" /> Project management</h2> + <p>To begin using Decoda, you need to create a project, or load an existing one. Decoda projects have a .deproj extension, and are simply a list of Lua files that are to be opened. You can create a project through menu Project -> New Project. Save your project first, so that Decoda knows what relative paths to use for the files. Then either add existing Lua files or create new one, through menu Project -> Add Add New File / Add Existing File.</p> + <p>Next you need to set up the executable that Decoda will run when debugging your files. Select menu Project -> Settings. A new dialog will open:<br /> + <img src="Static/decoda_debug_settings.png" /></p> + <p>In the debugging section, fill in the full path to Cuberite.exe, or click the triple-dot button to browse for the file. Note that the Working directory will be automatically filled in for you with the folder where the executable is (until the last backslash). This is how it's supposed to work, don't change it; if it for some reason doesn't update, copy and paste the folder name from the Command edit box. All done, you can close this dialog now.</p> + + <h2><img src="Static/decoda_logo.png" /> Debugging</h2> + <p>You are now ready to debug your code. Before doing that, though, don't forget to save your project file. If you haven't done so already, enable your plugin in the settings.ini file. If you want the program to break at a certain line, it is best to set the breakpoint before starting the program. Set the cursor on the line and hit F9 (or use menu Debug -> Toggle Breakpoint) to toggle a breakpoint on that line. Finally, hit F5, or select menu Debug -> Start to launch Cuberite under the debugger. The Cuberite window comes up and loads your plugin. If Decoda displays the Project Settings dialog instead, you haven't set up the executable to run, see the Project management section for instructions.</p> + <p>At this point you will see that Decoda starts adding new items to your project. All the files for all plugins are added temporarily. Don't worry, they are only temporary, they will be removed again once the debugging session finishes. You can tell the temporary files from the regular files by their icon, it's faded out. Decoda handles all the files that Cuberite loads, so you can actually debug any of those faded files, too.</p> + <p>If there's an error in the code, the Decoda window will flash and a dialog box will come up, describing the error and taking you to the line where it occured. Note that the execution is paused in the thread executing the plugin, so until you select Debug -> Continue from the menu (F5), Cuberite won't be fully running. You can fix the error and issue a "reload" command in Cuberite console to reload the plugin code anew (Cuberite doesn't detect changes in plugin code automatically).</p> + <p>If the execution hits a breakpoint, the Decoda window will flash and a yellow arrow is displayed next to the line. You can step through the code using F10 and F11, just like in MSVS. You can also use the Watch window to inspect variable values, or simply hover your mouse over a variable to display its value in the tooltip.</p> + + <h2><img src="Static/decoda_logo.png" /> Limitations</h2> + <p>So far everything seems wonderful. Unfortunately, it doesn't always go as easy. There are several limits to what Decoda can do:</p> + <ul> + <li>When the program encounters a logical bug (using a nil value, calling a non-existent function etc.), Decoda will break, but usually the Watch window and the tooltips are showing nonsense values. You shouldn't trust them in such a case, if you kep running into such a problem regularly, put console logging functions (LOG) in the code to print out any info you need prior to the failure.</li> + <li>Sometimes breakpoints just don't work. This is especially true if there are multiple plugins that have files of the same name. Breakpoints will never work after changing the code and reloading the plugin in Cuberite; you need to stop the server and start again to reenable breakpoints.</li> + <li>Most weirdly, sometimes Decoda reports an error, but instead of opening the current version of the file, opens up another window with old contents of the file. Watch for this, because you could overwrite your new code if you saved this file over your newer file. Fortunately enough, Decoda will always ask you for a filename before saving such a file.</li> + <li>Decoda stores the project in two files. The .deproj file has the file list, and should be put into version control systems. The .deuser file has the settings (debugged application etc.) and is per-user specific. This file shouldn't go to version control systems, because each user may have different paths for the debuggee.</li> + <li>Unfortunately for us Windows users, the Decoda project file uses Unix-lineends (CR only). This makes it problematic when checking the file into a version control system, since those usually expect windows (CRLF) lineends; I personally convert the lineends each time I edit the project file using <a href="http://jsimlo.sk/notepad/">TED Notepad</a>.</li> + </ul> + </div> + </body> +</html> diff --git a/Server/Plugins/APIDump/SettingUpZeroBrane.html b/Server/Plugins/APIDump/SettingUpZeroBrane.html new file mode 100644 index 000000000..d2f5bb483 --- /dev/null +++ b/Server/Plugins/APIDump/SettingUpZeroBrane.html @@ -0,0 +1,46 @@ +<!DOCTYPE html> + +<html> + <head> + <title>Cuberite - Setting up ZeroBrane Studio</title> + <link rel="stylesheet" type="text/css" href="main.css" /> + <link rel="stylesheet" type="text/css" href="prettify.css" /> + <script src="prettify.js"></script> + <script src="lang-lua.js"></script> + <meta charset="UTF-8"> + </head> + <body> + <div id="content"> + <h1>Setting up the ZeroBrane Studio IDE</h1> + <p> + This article will explain how to set up ZeroBrane Studio, an IDE for writing Lua code, so that you can develop Cuberite plugins with the comfort of an IDE.</p> + + <h2><img src="Static/zbs_logo.png" /> About ZeroBrane Studio</h2> + + <p>To quickly introduce ZeroBrane Studio, it is an IDE for writing Lua code.

It is written using the multiplatform WxWidgets toolkit, and runs on multiple platforms, including Windows, Linux and MacOS.</p> + <p>Here's a screenshot of a default ZBS window with the debugger stepping through the code (scaled down):<br /> + <img src="Static/zbs_workspace.png" /></p> + <p>As you can see, you can set breakpoints in the code, inspect variables' values, view the Lua call-stacks.</p> + <p>ZBS is open-source, the sources are on GitHub: <a href="https://github.com/pkulchenko/ZeroBraneStudio">https://github.com/pkulchenko/ZeroBraneStudio</a>. The project's homepage is at <a href="http://studio.zerobrane.com/">http://studio.zerobrane.com/</a>. + + <h2><img src="Static/zbs_logo.png" /> First-time setup</h2> + <p>Since ZBS is a universal Lua IDE, you need to first set it up so that it is ready for Cuberite plugin development. For that, you need to download one file, <a href="https://raw.githubusercontent.com/pkulchenko/ZeroBranePackage/master/mcserver.lua">mcserver.lua</a> from the <a href="https://github.com/pkulchenko/ZeroBranePackage">ZBS's plugin repository</a>. Place that file in the "packages" folder inside your ZBS's folder. Note that there are other useful plugins in the repository and you may want to have a look there later on to further customize your ZBS. To install them, simply save them into the same folder.</p> + <p>Next you should install the code-completion support specific for Cuberite. You should repeat this step from time to time, because the API evolves in time so new functions and classes are added to it quite often. You should have an APIDump plugin in your Cuberite installation. Enable the APIDump plugin in the server settings, it's very cheap to keep it enabled and it doesn't cost any performance during normal gameplay. To generate the code-completion support file, enter the <code style="background: #ddd; border: 1px solid #aaa">api</code> command into the server console. This will create a new file, "mcserver_api.lua", next to the Cuberite executable. Move that file into the "api/lua" subfolder inside your ZBS's folder.</p> + <p>After you download the mcserver.lua file and install the completion support, you need to restart ZBS in order for the plugin to load. If there are no errors, you should see two new items in the Project -> Lua Interpreter submenu: "Cuberite - debug mode" and "Cuberite - release mode". The only difference between the two is which filename they use to launch Cuberite - mcserver_debug(.exe) for the debug option and "mcserver(.exe)" for the release option. If you built your own Cuberite executable and you built it in debug mode, you should select the debug mode option. In all other cases, including if you downloaded the already-compiled Cuberite executable from the internet, you should select the release mode option.</p> + <p>For a first time user, it might be a bit overwhelming that there are no GUI settings in the ZBS, yet the IDE is very configurable. There are two files that you edit in order to change settings, either system-wide (all users of the computer share those settings) or user-wide (the settings are only for a specific user of the computer). Those files are regular Lua sources and you can quickly locate them and edit them from within the IDE itself, select Edit -> Preferences -> Settings: XYZ from the menu, with XYZ being either System or User.</p> + <p>There is a documentation on most of the settings on ZBS's webpage, have a look at <a href="http://studio.zerobrane.com/documentation.html">http://studio.zerobrane.com/documentation.html</a>, especially the Preferences section. Personally I recommend setting editor.usetabs to true and possibly adjusting the editor.tabwidth, turn off the editor.smartindent feature and for debugging the option debugger.alloweditting should be set to true unless you feel like punishing yourself.</p> + + <h2><img src="Static/zbs_logo.png" /> Project management</h2> + <p>ZBS works with projects, it considers all files and subfolder in a specific folder to be a project. There's no need for a special project file nor for adding individual files to the workspace, all files are added automatically. To open a Cuberite plugin as the project, click the triple-dot button in the Project pane, or select Project -> Project directory -> Choose... from the menu. Browse and select the Cuberite plugin's folder. ZBS will load all the files in the plugin's folder and you can start editting code.</p> + <p>Note that although ZBS allows you to work with subfolders in your plugins (and you should, especially with larger plugins), the current Cuberite ZBS plugin will not be able to start debugging unless you have a file open in the editor that is at the root level of the Cuberite plugin's folder.</p> + + <h2><img src="Static/zbs_logo.png" /> Debugging</h2> + <p>You are now ready to debug your code. Before doing that, though, don't forget to save your project files. If you haven't done so already, enable your plugin in the settings.ini file. If you want the program to break at a certain line, it is best to set the breakpoint before starting the program. Set the cursor on the line and hit F9 (or use menu Project -> Toggle Breakpoint) to toggle a breakpoint on that line. Finally, hit F5, or select menu Project -> Start Debugging to launch Cuberite under the debugger. The Cuberite window comes up and loads your plugin. If the window doesn't come up, inspect the Output pane in ZBS, there are usually two reasons for failure:<ul> + <li>Your code in the currently open file has a hard syntax error. These are reported as "Compilation error" in the Output pane, double-click the line to go to the error</li> + <li>ZBS cannot find the Cuberite executable. Make sure you are editting a file two levels down the folder hierarchy from the Cuberite executable and that the Cuberite executable is named properly (mcserver[.exe] or mcserver_debug[.exe]). Also make sure you have selected the right Interpreter (menu Project -> Lua Interpreter).</li> + </ul></p> + <p>Once running, if the execution hits a breakpoint, the ZBS window will come up and a green arrow is displayed next to the breakpoint line. You can step through the code using F10 (Step Into) and Shift+F10 (Step Over). You can also use the Watch window to inspect variable values, or simply hover your mouse over a variable to display its value in the tooltip. Use the Remote console pane to execute commands directly *inside* the Cuberite's plugin context.</p> + <p>You can also use the Project -> Break menu item to break into the debugger as soon as possible. You can also set breakpoints while the Cuberite plugin is running. Note that due to the way in which the debugger is implemented, Cuberite may execute some more Lua code before the break / breakpoint comes into effect. If Cuberite is not executing any Lua code in your plugin, it will not break until the plugin code kicks in again. This may result in missed breakpoints and delays before the Break command becomes effective. Therefore it's best to set breakpoints before running the program, or while the program is waiting in another breakpoint.</p> + </div> + </body> +</html> diff --git a/Server/Plugins/APIDump/Static/.gitignore b/Server/Plugins/APIDump/Static/.gitignore new file mode 100644 index 000000000..8d1c8b69c --- /dev/null +++ b/Server/Plugins/APIDump/Static/.gitignore @@ -0,0 +1 @@ + diff --git a/Server/Plugins/APIDump/Static/decoda_debug_settings.png b/Server/Plugins/APIDump/Static/decoda_debug_settings.png Binary files differnew file mode 100644 index 000000000..462d517b4 --- /dev/null +++ b/Server/Plugins/APIDump/Static/decoda_debug_settings.png diff --git a/Server/Plugins/APIDump/Static/decoda_logo.png b/Server/Plugins/APIDump/Static/decoda_logo.png Binary files differnew file mode 100644 index 000000000..fb446b62c --- /dev/null +++ b/Server/Plugins/APIDump/Static/decoda_logo.png diff --git a/Server/Plugins/APIDump/Static/decoda_workspace.png b/Server/Plugins/APIDump/Static/decoda_workspace.png Binary files differnew file mode 100644 index 000000000..7e626dae9 --- /dev/null +++ b/Server/Plugins/APIDump/Static/decoda_workspace.png diff --git a/Server/Plugins/APIDump/Static/zbs_logo.png b/Server/Plugins/APIDump/Static/zbs_logo.png Binary files differnew file mode 100644 index 000000000..c8d6d6278 --- /dev/null +++ b/Server/Plugins/APIDump/Static/zbs_logo.png diff --git a/Server/Plugins/APIDump/Static/zbs_workspace.png b/Server/Plugins/APIDump/Static/zbs_workspace.png Binary files differnew file mode 100644 index 000000000..9ce17e35a --- /dev/null +++ b/Server/Plugins/APIDump/Static/zbs_workspace.png diff --git a/Server/Plugins/APIDump/UsingChunkStays.html b/Server/Plugins/APIDump/UsingChunkStays.html new file mode 100644 index 000000000..a7cb5302a --- /dev/null +++ b/Server/Plugins/APIDump/UsingChunkStays.html @@ -0,0 +1,167 @@ +<!DOCTYPE html> +<html> + <head> + <title>Cuberite - Using ChunkStays</title> + <link rel="stylesheet" type="text/css" href="main.css" /> + <link rel="stylesheet" type="text/css" href="prettify.css" /> + <script src="prettify.js"></script> + <script src="lang-lua.js"></script> + <meta charset="UTF-8"> + </head> + <body> + <div id="content"> + <h1>Using ChunkStays</h1> + <p> + A plugin may need to manipulate data in arbitrary chunks, and it needs a way to make the server + guarantee that the chunks are available in memory.</p> + + <h2>The problem</h2> + <p> + Usually when plugins want to manipulate larger areas of world data, they need to make sure that the + server has the appropriate chunks loaded in the memory. When the data being manipulated can be further + away from the connected players, or the data is being manipulated from a console handler, there is a + real chance that the chunks are not loaded.</p> + <p> + This gets even more important when using the <a href="cBlockArea.html">cBlockArea</a> class for reading + and writing. Those functions will fail when any of the required chunks aren't valid. This means that + either the block area has incomplete data (Read() failed) or incomplete data has been written to the + world (Write() failed). Recovery from this is near impossible - you can't simply read or write again + later, because the world may have changed in the meantime.</p> + + <h2>The solution</h2> + <p> + The naive solution would be to monitor chunk loads and unloads, and postpone the operations until all + the chunks are available. This would be quite ineffective and also very soon it would become very + difficult to maintain, if there were multiple code paths requiring this handling.</p> + <p> + An alternate approach has been implemented, accessible through a single (somewhat hidden) function + call: <a href="cWorld.html">cWorld:ChunkStay()</a>. All that this call basically does is, it tells the + server "Load these chunks for me, and call this callback function once you have them all." And the + server does exactly that - it remembers the callback and asks the world loader / generator to provide + the chunks. Once the chunks become available, it calls the callback function for the plugin.</p> + <p> + There are a few gotcha-s, though. If the code that was requesting the read or write had access to some + of the volatile objects, such as <a href="cPlayer.html">cPlayer</a> or + <a href="cEntity.html">cEntity</a> objects, those cannot be accessed by the callback anymore, because + they may have become invalid in the meantime - the player may have disconnected, the entity may have + despawned. So the callback must use the longer way to access such objects, such as calling + <a href="cWorld.html">cWorld:DoWithEntityByID()</a> or + <a href="cWorld.html">cWorld:DoWithPlayer()</a>.</p> + + <h2>The example</h2> + <p> + As a simple example, consider a theoretical plugin that allows a player to save the immediate + surroundings of the spawn into a schematic file. The player issues a command to initiate the save, and + the plugin reads a 50 x 50 x 50 block area around the spawn into a cBlockArea and saves it on the disk + as "<PlayerName>_spawn.schematic". When it's done with the saving, it wants to send a message to the + player to let them know the command has succeeded.</p> + <p> + The first attempt shows the naive approach. It simply reads the block area and saves it, then sends the + message. I'll repeat once more, this code is <b>the wrong way</b> to do it!</p> +<pre class="prettyprint lang-lua"> +function HandleCommandSaveSpawn(a_Split, a_Player) + -- Get the coords for the spawn: + local SpawnX = a_Player:GetWorld():GetSpawnX() + local SpawnY = a_Player:GetWorld():GetSpawnY() + local SpawnZ = a_Player:GetWorld():GetSpawnZ() + local Bounds = cCuboid(SpawnX - 25, SpawnY - 25, SpawnZ - 25, SpawnX + 25, SpawnY + 25, SpawnZ + 25) + Bounds:ClampY(0, 255) + + -- Read the area around spawn into a cBlockArea, save to file: + local Area = cBlockArea() + local FileName = a_Player:GetName() ..

Most operations on Cuberite objects requires synchronization, that Cuberite provides automatically and transparently to plugins - when a block is written, the chunkmap is locked, or when an entity is being manipulated, the entity list is locked. Each plugin also has a mutex lock, so that only one thread at a time may be executing plugin code.</p> + <p> + This locking can be a source of deadlocks for plugins that are not written carefully.</p> + + <h2>Example scenario</h2> + <p>Consider the following example. A plugin provides a webadmin page that allows the admin to kick players off the server. When the admin presses the "Kick" button, the plugin calls cWorld:DoWithPlayer() with a callback to kick the player. Everything seems to be working fine now.</p> + <p> + A new feature is developed in the plugin, now the plugin adds a new in-game command so that the admins can kick players while they're playing the game. The plugin registers a command callback with cPluginManager.AddCommand(). Now there are problems bound to happen.</p> + <p> + Suppose that two admins are in, one is using the webadmin and the other is in-game. Both try to kick a player at the same time. The webadmin locks the plugin, so that it can execute the plugin code, but right at this moment the OS switches threads. The world thread locks the world so that it can access the list of in-game commands, receives the in-game command, it tries to lock the plugin. The plugin is already locked, so the world thread is put on hold. After a while, the webadmin thread is woken up again and continues processing. It tries to lock the world so that it can traverse the playerlist, but the lock is already held by the world thread. Now both threads are holding one lock each and trying to grab the other lock, and are therefore deadlocked.</p> + + <h2>How to avoid the deadlock</h2> + <p> + There are two main ways to avoid such a deadlock. The first approach is using tasks: Everytime you need to execute a task inside a world, instead of executing it, queue it, using <a href="cWorld.html">cWorld</a>:QueueTask(). This handy utility can will call the given function inside the world's TickThread, thus eliminating the deadlock, because now there's only one thread. However, this approach will not let you get data back. You cannot query the player list, or the entities, or anything - because when the task runs, the webadmin page has already been served to the browser.</p> + <p> + To accommodate this, you'll need to use the second approach - preparing and caching data in the tick thread, possibly using callbacks. This means that the plugin will have global variables that will store the data, and update those variables when the data changes; then the webserver thread will only read those variables, instead of calling the world functions. For example, if a webpage was to display the list of currently connected players, the plugin should maintain a global variable, g_WorldPlayers, which would be a table of worlds, each item being a list of currently connected players. The webadmin handler would read this variable and create the page from it; the plugin would use HOOK_PLAYER_JOINED and HOOK_DISCONNECT to update the variable.</p> + + <h2>What to avoid</h2> + <p> + Now that we know what the danger is and how to avoid it, how do we know if our code is susceptible?</p> + <p> + The general rule of thumb is to avoid calling any functions that read or write lists of things in the webserver thread. This means most ForEach() and DoWith() functions. Only <a href="cRoot.html">cRoot</a>:ForEachWorld() is safe - because the list of worlds is not expected to change, so it is not guarded by a mutex. Getting and setting world's blocks is, naturally, unsafe, as is calling other plugins, or creating entities.</p> + + <h2>Example</h2> + The Core has the facility to kick players using the web interface. It used the following code for the kicking (inside the webadmin handler): +<pre class="prettyprint lang-lua"> +local KickPlayerName = Request.Params["players-kick"] +local FoundPlayerCallback = function(Player) + if (Player:GetName() == KickPlayerName) then + Player:GetClientHandle():Kick("You were kicked from the game!") + end +end +cRoot:Get():FindAndDoWithPlayer(KickPlayerName, FoundPlayerCallback) +</pre> +The cRoot:FindAndDoWithPlayer() is unsafe and could have caused a deadlock. The new solution is queue a task; but since we don't know in which world the player is, we need to queue the task to all worlds: +<pre class="prettyprint lang-lua"> +cRoot:Get():ForEachWorld( -- For each world... + function(World) + World:QueueTask( -- ... queue a task... + function(a_World) + a_World:DoWithPlayer(KickPlayerName, -- ... to walk the playerlist... + function (a_Player) + a_Player:GetClientHandle():Kick("You were kicked from the game!") -- ... and kick the player + end + ) + end + ) + end +) +</pre> + <script> + prettyPrint(); + </script> + </div> + </body> +</html>

It details basic requirements + for a plugin, explains how to register a hook and bind a command, and gives plugin + standards details. + </p> + <p> + Let us begin. In order to begin development, we must firstly obtain a compiled copy + of Cuberite, and make sure that the Core plugin is within the Plugins folder, and activated. + Core handles much of the Cuberite end-user experience and gameplay will be very bland without it. + </p> + <h2>Creating the basic template</h2> + <p> + Plugins are written in Lua. Therefore, create a new Lua file. You can create as many files as you wish, with + any filename - Cuberite bungs them all together at runtime, however, let us create a file called main.lua for now. + Format it like so: + </p> + <pre class="prettyprint lang-lua"> +PLUGIN = nil + +function Initialize(Plugin) + Plugin:SetName("NewPlugin") + Plugin:SetVersion(1) + + -- Hooks + + PLUGIN = Plugin -- NOTE: only needed if you want OnDisable() to use GetName() or something like that + + -- Command Bindings + + LOG("Initialised " .. Plugin:GetName() .. " v." .. Plugin:GetVersion()) + return true +end + +function OnDisable() + LOG(PLUGIN:GetName() .. " is shutting down...") +end + </pre> + <p> + Now for an explanation of the basics. + <ul> + <li><b>function Initialize</b> is called on plugin startup. It is the place where the plugin is set up.</li> + <li><b>Plugin:SetName</b> sets the name of the plugin.</li> + <li><b>Plugin:SetVersion</b> sets the revision number of the plugin. This must be an integer.</li> + <li><b>LOG</b> logs to console a message, in this case, it prints that the plugin was initialised.</li> + <li>The <b>PLUGIN</b> variable just stores this plugin's object, so GetName() can be called in OnDisable (as no Plugin parameter is passed there, contrary to Initialize). + This global variable is only needed if you want to know the plugin details (name, etc.) when shutting down.</li> + <li><b>function OnDisable</b> is called when the plugin is disabled, commonly when the server is shutting down. Perform cleanup and logging here.</li> + </ul> + Be sure to return true for this function, else Cuberite thinks you plugin had failed to initialise and prints a stacktrace with an error message. + </p> + + <h2>Registering hooks</h2> + <p> + Hooks are things that Cuberite calls when an internal event occurs. For example, a hook is fired when a player places a block, moves, + logs on, eats, and many other things. For a full list, see <a href="index.html">the API documentation</a>. + </p> + <p> + A hook can be either informative or overridable. In any case, returning false will not trigger a response, but returning true will cancel + the hook and prevent it from being propagated further to other plugins. An overridable hook simply means that there is visible behaviour + to a hook's cancellation, such as a chest being prevented from being opened. There are some exceptions to this where only changing the value the + hook passes has an effect, and not the actual return value, an example being the HOOK_KILLING hook. See the API docs for details. + </p> + <p> + To register a hook, insert the following code template into the "-- Hooks" area in the previous code example. + </p> + <pre class="prettyprint lang-lua"> +cPluginManager.AddHook(cPluginManager.HOOK_NAME_HERE, FunctionNameToBeCalled) + </pre> + <p> + What does this code do? + <ul> + <li><b>cPluginManager.AddHook</b> registers the hook. The hook name is the second parameter. See the previous API documentation link for a list of all hooks.</li> + </ul> + What about the third parameter, you ask? Well, it is the name of the function that Cuberite calls when the hook fires. It is in this + function that you should handle or cancel the hook. + </p> + <p> + So in total, this is a working representation of what we have so far covered. + </p> + <pre class="prettyprint lang-lua"> +function Initialize(Plugin) + Plugin:SetName("DerpyPlugin") + Plugin:SetVersion(1) + + cPluginManager.AddHook(cPluginManager.HOOK_PLAYER_MOVING, OnPlayerMoving) + + LOG("Initialised " .. Plugin:GetName() .. " v." .. Plugin:GetVersion()) + return true +end + +function OnPlayerMoving(Player) -- See API docs for parameters of all hooks + return true -- Prohibit player movement, see docs for whether a hook is cancellable +end + </pre> + <p> + So, that code stops the player from moving. Not particularly helpful, but yes :P. Note that ALL documentation is available + on the main API docs page, so if ever in doubt, go there. + </p> + <h2>Binding a command</h2> + <h3>Format</h3> + <p> + So now we know how to hook into Cuberite, how do we bind a command, such as /explode, for a player to type? That is more complicated. + We firstly add this template to the "-- Command bindings" section of the initial example: + </p> + <pre class="prettyprint lang-lua"> +-- ADD THIS IF COMMAND DOES NOT REQUIRE A PARAMETER (/explode) +cPluginManager.BindCommand("/commandname", "permissionnode", FunctionToCall, " - Description of command") + +-- ADD THIS IF COMMAND DOES REQUIRE A PARAMETER (/explode Notch) +cPluginManager.BindCommand("/commandname", "permissionnode", FunctionToCall, " ~ Description of command and parameter(s)") + </pre> + <p> + What does it do, and why are there two? + <ul> + <li><b>PluginManager:BindCommand</b> binds a command. It takes the command name (with a slash), the permission a player needs to execute the command, the function + to call when the command is executed, and a description of the command.</li> + </ul> + The command name is pretty self explanatory. The permission node is basically just a <b>string</b> that the player's group needs to have, so you can have anything in there, + though we recommend a style such as "derpyplugin.explode". The function to call is like the ones with Hooks, but with some fixed parameters which we will come on to later, + and the description is a description of the command which is shown when "/help" is typed. + </p> + <p> + So why are there two? Standards. A plugin that accepts a parameter MUST use a format for the description of " ~ Description of command and parms" + whereas a command that doesn't accept parameters MUST use " - Description of command" instead. Be sure to put a space before the tildes or dashes. + Additionally, try to keep the description brief and on one line on the client. + </p> + <h3>Parameters</h3> + <p> + What parameters are in the function Cuberite calls when the command is executed? A 'Split' array and a 'Player' object. + </p> + <h4>The Split Array</h4> + <p> + The Split array is an array of all text submitted to the server, including the actual command. Cuberite automatically splits the text into the array, + so plugin authors do not need to worry about that. An example of a Split array passed for the command, "/derp zubby explode" would be:<br /><br /> +    /derp (Split[1])<br /> +    zubby (Split[2])<br /> +    explode (Split[3])<br /> + <br /> +    The total amount of parameters passed were: 3 (#Split) + </p> + <h4>The Player Object and sending them messages</h4> + <p> + The Player object is basically a pointer to the player that has executed the command. You can do things with them, but most common is sending + a message. Again, see the API documentation for fuller details. But, you ask, how <i>do</i> we send a message to the client? + </p> + <p> + There are dedicated functions used for sending a player formatted messages. By format, I refer to coloured prefixes/coloured text (depending on configuration) + that clearly categorise what type of message a player is being sent. For example, an informational message has a yellow coloured [INFO] prefix, and a warning message + has a rose coloured [WARNING] prefix. A few of the most used functions are listed here, but see the API docs for more details. Look in the cRoot, cWorld, and cPlayer sections + for functions that broadcast to the entire server, the whole world, and a single player, respectively. + </p> + <pre class="prettyprint lang-lua"> +-- Format: §yellow[INFO] §white%text% (yellow [INFO], white text following it) +-- Use: Informational message, such as instructions for usage of a command +Player:SendMessageInfo("Usage: /explode [player]") + +-- Format: §green[INFO] §white%text% (green [INFO] etc.) +-- Use: Success message, like when a command executes successfully +Player:SendMessageSuccess("Notch was blown up!") + +-- Format: §rose[INFO] §white%text% (rose coloured [INFO] etc.) +-- Use: Failure message, like when a command was entered correctly but failed to run, such as when the destination player wasn't found in a /tp command +Player:SendMessageFailure("Player Salted was not found") + </pre> + <p> + Those are the basics. If you want to output text to the player for a reason other than the three listed above, and you want to colour the text, simply concatenate + "cChatColor.*colorhere*" with your desired text, concatenate being "..". See the API docs for more details of all colours, as well as details on logging to console with + LOG("Text"). + </p> + <h2>Final example and conclusion</h2> + <p> + So, a working example that checks the validity of a command, and blows up a player, and also refuses pickup collection to players with >100ms ping. + </p> + <pre class="prettyprint lang-lua"> +function Initialize(Plugin) + Plugin:SetName("DerpyPluginThatBlowsPeopleUp") + Plugin:SetVersion(9001) + + cPluginManager.BindCommand("/explode", "derpyplugin.explode", Explode, " ~ Explode a player"); + + cPluginManager:AddHook(cPluginManager.HOOK_COLLECTING_PICKUP, OnCollectingPickup) + + LOG("Initialised " ..

" was successfully exploded") + HasExploded = true; + return true -- Signalize to Cuberite that we do not need to call this callback for any more players + end + end + + -- Tell Cuberite to loop through all players and call the callback above with the Player object it has found + cRoot:Get():FindAndDoWithPlayer(Split[2], ExplodePlayer) + + if not(HasExploded) then + -- We have not broken out so far, therefore, the player must not exist, send failure + Player:SendMessageFailure(Split[2] .. " was not found") + end + + return true +end + +function OnCollectingPickup(Player, Pickup) -- Again, see the API docs for parameters of all hooks. In this case, it is a Player and Pickup object + if (Player:GetClientHandle():GetPing() > 100) then -- Get ping of player, in milliseconds + return true -- Discriminate against high latency - you don't get drops :D + else + return false -- You do get the drops! Yay~ + end +end + </pre> + <p> + Make sure to read the comments for a description of what everything does. Also be sure to return true for all <b>command</b> handlers, unless you want Cuberite to print out an "Unknown command" message + when the command gets executed :P. Make sure to follow standards - use CoreMessaging.lua functions for messaging, dashes for no parameter commands and tildes for vice versa, + and finally, <a href="index.html">the API documentation</a> is your friend! + </p> + <p> + Happy coding ;) + </p> + + <script> + prettyPrint(); + </script> + </div> + </body> +</html> diff --git a/Server/Plugins/APIDump/lang-lua.js b/Server/Plugins/APIDump/lang-lua.js new file mode 100644 index 000000000..7e44cca0a --- /dev/null +++ b/Server/Plugins/APIDump/lang-lua.js @@ -0,0 +1,2 @@ +PR.registerLangHandler(PR.createSimpleLexer([["pln",/^[\t\n\r \xa0]+/,null,"\t\n\r \u00a0"],["str",/^(?:"(?:[^"\\]|\\[\S\s])*(?:"|$)|'(?:[^'\\]|\\[\S\s])*(?:'|$))/,null,"\"'"]],[["com",/^--(?:\[(=*)\[[\S\s]*?(?:]\1]|$)|[^\n\r]*)/],["str",/^\[(=*)\[[\S\s]*?(?:]\1]|$)/],["kwd",/^(?:and|break|do|else|elseif|end|false|for|function|if|in|local|nil|not|or|repeat|return|then|true|until|while)\b/,null],["lit",/^[+-]?(?:0x[\da-f]+|(?:\.\d+|\d+(?:\.\d*)?)(?:e[+-]?\d+)?)/i], +["pln",/^[_a-z]\w*/i],["pun",/^[^\w\t\n\r \xa0][^\w\t\n\r "'+=\xa0-]*/]]),["lua"]); diff --git a/Server/Plugins/APIDump/main.css b/Server/Plugins/APIDump/main.css new file mode 100644 index 000000000..e5685caab --- /dev/null +++ b/Server/Plugins/APIDump/main.css @@ -0,0 +1,68 @@ +html +{ + background-color: #C0C0C0; +} + +table +{ + background-color: #fff; + border-spacing: 0px; + border-collapse: collapse; + border-color: gray; +} + +tr +{ + display: table-row; + vertical-align: inherit; + border-color: inherit; +} + +td, th +{ + display: table-cell; + vertical-align: inherit; + padding: 3px; + border: 1px solid #ccc; +} + +pre +{ + border: 1px solid #ccc; + background-color: #eee; + -moz-tab-size: 2; + -o-tab-size: 2; + -webkit-tab-size: 2; + -ms-tab-size: 2; + tab-size: 2; +} + +body +{ + min-width: 400px; + max-width: 1200px; + width: 95%; + margin: 10px auto; + background-color: white; + border: 4px #FF8C00 solid; + border-radius: 20px; + font-family: Calibri, Trebuchet MS; +} + +header +{ + text-align: center; + font-family: Segoe UI Light, Helvetica; +} + +footer +{ + text-align: center; + font-family: Segoe UI Light, Helvetica; +} + +#content, #timestamp +{ + padding: 0px 25px 25px 25px; +} + diff --git a/Server/Plugins/APIDump/main_APIDump.lua b/Server/Plugins/APIDump/main_APIDump.lua new file mode 100644 index 000000000..4892d477d --- /dev/null +++ b/Server/Plugins/APIDump/main_APIDump.lua @@ -0,0 +1,1685 @@ +-- main.lua + +-- Implements the plugin entrypoint (in this case the entire plugin) + + + + + +-- Global variables: +local g_Plugin = nil +local g_PluginFolder = "" +local g_Stats = {} +local g_TrackedPages = {} + + + + + + +local function LoadAPIFiles(a_Folder, a_DstTable) + assert(type(a_Folder) == "string") + assert(type(a_DstTable) == "table") + + local Folder = g_PluginFolder .. a_Folder; + for _, fnam in ipairs(cFile:GetFolderContents(Folder)) do + local FileName = Folder .. fnam; + -- We only want .lua files from the folder: + if (cFile:IsFile(FileName) and fnam:match(".*%.lua$")) then + local TablesFn, Err = loadfile(FileName); + if (type(TablesFn) ~= "function") then + LOGWARNING("Cannot load API descriptions from " ..
