IRC Mod for Minetest (C) 2012 Diego Martínez INTRODUCTION ------------ This mod is just a glue between luasocket, LuaIRC, and Minetest. It provides a two-way communication between the in-game chat, and an arbitrary IRC channel. COMPILING --------- Make sure you have CMake (http://cmake.org/), and of course, a C compiler, on your system before proceeding. For Windows, try MinGW32 (http://mingw.org/). For Unix-based systems, you should not have any problems with the C compiler since there's one (almost) always available. Puppy Linux users of course need a separate `devx.sfs' (from the same place where you got the Puppy ISO), since vanilla Puppy does not come with `gcc'. See your Puppy docs for more info about how to install additional SFS files. Quick one line build for linux. git clone https://github.com/kaeza/minetest-irc.git && cd minetest-irc && mkdir build && cd build && cmake .. && make && make pack_mod && cp -R irc Please change the "cp -R irc" to fit your install of minetest. To compile and "pack" the mod: - Open a command prompt/terminal and CD to the minetest-irc directory. - Create a directory named "Build", and CD into it: mkdir Build cd Build - Run CMake to generate the build system (see your CMake docs for more information about command line options, in particular the `-G' option). cmake .. - Use the build tool for the generated build system to compile the native library. For example, if using Microsoft Visual Studio, open the generated workspace and build from there. If using make, just run "make" from within the Build directory. - Again use the build tool to invoke the `pack_mod' target. For example, if using `make', run "make pack_mod" from within the build directory. This will create an `irc' directory inside the build directory. This `irc' directory will be ready to be deployed to your Minetest mods directory. INSTALLING ---------- Just put the created `irc' directory in any of the directories where Minetest looks for mods. For more information, see: http://wiki.minetest.com/wiki/Installing_mods SETTINGS -------- All settings are changed in the `config.lua' file. If any of these settings are either nil or false, the default value is used. mt_irc.server (string, default "irc.freenode.net") This is the IRC server the mod connects to. mt_irc.channel (string, default "##mt-irc-mod") The IRC channel to join. mt_irc.dtime (number, default 0.2) This is the time in seconds between updates in the connection. In order not to block the game, the mod must periodically "poll" the connection to both send messages to, and receive messages from the channel. A high value means slower connection to IRC, but possibly better response from the game. A low value means the mod "polls" the connection more often, but can make the game hang. It allows fractional values. mt_irc.timeout (number, default 60.0) Underlying socket timeout in seconds. This is the time before the system drops an idle connection. mt_irc.server_nick (string, default "minetest-"..) Nickname used as "proxy" for the in-game chat. "" is the server IP address packed as a 32 bit integer. (Currently, it's just a random 32 bit number). mt_irc.password (string, default "") Password to use when connecting to the server. mt_irc.message_format_out (string, default "<$(name)> $(message)") This specifies how to send the messages from in-game to IRC. The strings can contain "macros" (or variable substitutions), which are specified as "$(macro_name)". Currently, these macros are supported: $(name) The name of the player sending the message. $(message) The actual message text. Any unrecognized macro will be left in the message verbatim. For example, if a user named "mtuser" is saying "Hello!", then: "<$(name)> $(message)" ...will yield... " Hello!" ...and... "$(name): $(message) $(xyz)" ...will yield... "mtuser: Hello! $(xyz)" mt_irc.message_format_in (string, default "<$(name)@IRC> $(message)") This specifies how the messages gotten from the IRC channel are displayed in-game. The strings can contain "macros" (or variable substitutions), which are specified as "$(macro_name)". Currently, these macros are supported: $(name) The nickname of the user sending the message. $(message) The actual message text. $(server) The IRC server. $(port) The IRC server port. $(channel) The IRC channel. In the default configuration, this will yield: Hello! mt_irc.debug (boolean, default false) Whether to output debug information. mt_irc.auto_connect (boolean, default false) If true, the bot is connected by default. If false, a player with `irc_admin' privilege has to use the /irc_connect command to connect to the server. mt_irc.auto_join (boolean, default false) If true, players join the channel automatically upon entering the game. If false, each user must manually use the /join command to join the channel. In any case, the players may use the /part command to opt-out of being in the channel. USAGE ----- Once the game is connected to the IRC channel, chatting using the 'T' or F10 hotkeys will send the messages to the channel, and will be visible by anyone. Also, when someone sends a message to the channel, that text will be visible in-game. This mod also adds a few chat commands: /msg Sends a private message to the IRC user whose nickname is `nick'. /join Join the IRC channel. /part Part the IRC channel. /irc_connect Connect the bot manually to the IRC network. /irc_disconnect Disconnect the bot manually to the IRC network (this does not shutdown the game). /irc_reconnect A combination of /irc_disconnect and /irc_connect. You can also send private messages from IRC to in-game players, though it's a bit tricky. To do it, you must send a private message to the bot (set with the `mt_irc.server_nick' option above), in the following format: >playername message For example, if there's a player named `mtuser', you can send him/her a private message with: /msg server_nick >mtuser Hello! To avoid possible misunderstandings (since all in-game players use the same IRC user to converse with you), the "proxy" user will reject any private messages that are not in that format, and will send back a nice reminder as a private message.
