Commit: Current

Additions to pcre2_halfwrap.h:

• Added compare member function to match_data
• • std::regex equivalent: std::match_result::compare
• • Essentially the same as ml[1].str().compare(ml[2].str())
• • Works with std::string, const char*, const unsigned char*, or match_data
• Added max_size member function to smatch
• Added swap member function to smatch
• • Same as std::smatch::swap
• Added basic regex_replace
• • Works just like the first instantiation of std::regex_replace
• • • Except the options are defined by pcre2, not compatible with std::regex's options as of yet.
• Aside from the other missing regex_replace versions, the only thing missing from full std::regex compatibility is std::match_results::format. Probably won't ever add this since it is relatively useless.

Commit: eaeab6a

Added better functionality to enable/disable the pcre2 library using the ./src/usePCRE2.sh file.
Addd an internal check to halfMod that will print an error when using pcre2 if pcre2 was not compiled with jit-compiling enabled.
Added copy constructors and assignment overloads for all classes to pcre2_halfwrap.h.

Commit: dc675bc

Added a new library: pcre2_halfwrap.h

• This library is disabled by default. To use this library instead of std::regex for all internal halfMod and API workings edit the ./src/usePCRE2.sh file and change the value to true.
• This is an experimental library, you must have PCRE2 installed before you can use it.
• PCRE2 boasts increased speeds thanks to JIT compilation. This should make halfMod keep up with server output much faster.
• To ensure plugin compatibility regardless of whether this library is used or not, use the rens namespace infront of your regex calls:
• • Currently supported regex calls:
• • • rens::regex
• • • rens::smatch
• • • rens::regex_search
• • • rens::regex_match
• All functionality should still (hopefully) be preserved.

Replaced all calls to clang in the compile scripts to clang++ instead of /usr/bin/clang++-3.8.

Commit: bf8a0ba

Fixed slight issues with launch script. I know, this happens every time D:

Hopefully fixed halfShell hanging on exit when ran from WSL. (But also introduced a compiler warning...)

Commit: 213cf08

halfMod Engine Updates:

• Cleaned up processThread a lot. Runs smarter and faster increasing the overall efficiency of halfMod.
• onConsoleReceive event callbacks are now properly called even when a console filter blocks output.
• onConsoleReceive will now properly block if non-0 is returned.
• onServerShutdownPost now requires an std::smatch like most other events. smatch[1] will be the exit status code of minecraft.
• onFakePlayerText will now be called instead of onPlayerText when fake commands/messages have been sent from halfShell as long as the command did not exist or block.

More improvements to the launch script:

• Each switch performs one job, any of them can be combined to produce desired output. (Some combinations may not achieve anything)
• • --no-halfshell launch Minecraft without halfShell.
• • --no-halfmod launch Minecraft and halfShell, but not halfMod.
• • --solo-halfmod launch only halfMod.
• • --no-restart starts halfShell/Minecraft only if it is not already running. Combine with --restart-halfmod to only restart halfMod.
• • --stop completely stop halfShell/Minecraft and halfMod. (Same as --solo-halfmod --no-halfmod --restart-halfmod --restart)
• • --stop-halfmod stop halfMod. Does not affect or launch halfShell/Minecraft. (Same as --solo-halfmod --no-halfmod --restart-halfmod)
• • --stop-minecraft stop halfShell/Minecraft. Does not affect or launch halfMod. (Same as --solo-halfmod --no-halfmod --restart)

Commit: 6922645

halfShell has received a major overhaul!

• No longer a seperate process from Minecraft. Now halfShell is a shared object file that is loaded directly into the JVM making it a legitimate wrapper.
• • Not only does this provide a nice speed boost, but it is much more reliable and resource friendly.
• screen is no longer a dependency.
• • This means input is no longer sanitized!
• • Single quotes are no longer replaced with backticks.
• • Escapes are handled properly now.
• • • This likely broke some halfMod plugins.
• Slight change to halfshell.conf
• • Replaced allowed-ips option with allowed-ip and multiple definitions can be used to allow more than one:

ip=127.0.0.1
port=9422
allowed-ip=127.0.0.1
allowed-ip=1.2.3.4

• • These ip and port settings are the default and are not required in the conf.
• • 127.0.0.1 is automatically allowed, so you shouldn't set it in a real conf.
• Server output now prints to console again.
• All commands can be run from either console input or through connected mods.
• Added new commands:
• • echo [message ...] Prints message to console. No substitution or evaluation is performed at all.
• • hs help or hs ? Displays help text for hs commands.
• • hs kick <N> [reason ...] Disconnects a connected mod. Can only be used from the console. See hs list for N.
• • hs quit [reason ...] Disconnects the mod from halfShell. Can only be used from a connected mod.
• The incoming handshake when connecting to halfShell has changed.
• • Format: <halfShell version>\t<Minecraft version>\t<world name>
• • Example: halfShell v0.4.0 1.13.1 "world"
• • If the mod connects before the verson or world data is printed from Minecraft, that data will simply be missing, but the tabs will always be present. So be sure your mod still has checks for those lines. This is mostly a feature in case the mod connects late.

Slight updates to halfMod to support the new halfShell.

Updates to starting server.sh script:

• Added a few more customizable options if you edit the file, complete with comments.
• • Memory settings
• • Default --quiet, --debug, and --verbose options.
• --auto-restart now applies to halfMod as well. Without it, halfMod will no longer auto restart.
• Added --restart-halfmod switch.
• • If this switch is present and halfMod is already running, it will be killed and restarted.
• • Without this switch, if --auto-restart is present, halfMod will only restart when it stops or crashes.

New halfMod plugin benchmark:

• Benchmark Command Performance
• Can benchmark how long (time and TPS) it takes to run a command N times.
• Can run a debug profile for N seconds. Outputs the results at the end.

Commit: 72f6f56

Fixed bug that required previous revert.
Fixed small bug with the urlchat plugin.

Commit: 62db81f

Smaller bug fix

Commit: d9bd253

Small revert to fix new bug

Commit: 2b86084

Added some color output to hm_info and hm_cvarinfo.

Commit: 544b9fb

Fixed a nasty bug with the cvar_rules plugin causing an aggressive halfShell launch loop. Minor halfMod engine optimizations.

Plugins changes:

• baseplayerinfo:
• • Now the hm_whois command will only output player IPs to admins that have root access.
• mailbox:
• • Updated hm_senditem for new Item nbt changes.
• disco:
• • Updated enchantments on armor for new Enchantments tag.
• cvar_rules:
• • Now properly handles empty lines and #comments in ./halfMod/config/gamerules.conf.
• statbar:
• • Updated for halfMod API changes.
• • Small bug fixes.

Commit: a442fcd

Fixed a few compile errors and updated a few plugins to conform to new methods.

Commit: 022b1e5

API Changes:

• Updated mcVerInt() to properly support pre-release snapshot version numbers.
• Plugins now link the unload event function dynamically. Allows more control, specifically with extensions.
• client in command callbacks is now a const hmPlayer ref object instead of a string.
• • Any function that accepts client as a string, now may also accept a hmPlayer object where it makes sense.
• • • Obviously it doesn't make sense to do hmGetPlayerUUID(const hmPlayer&) because if you have the object, you have the UUID.
• findCmd, findEvent, findTimer, and findHook now all return bools, but assign a reference variable to the found object.
• • No longer a copy.
• Added hmGetPlayerPtr function. Just like hmGetPlayerInfo except returns as a pointer to the object.

Engine Changes:

• Timer overhaul.
• • Now when halfMod is idle, it will truely use 0% CPU until receiving data from minecraft, stdin, or a timer is ready to trigger.
• • Timers are now much more accurate, to a small fraction of milliseconds.
• • Micro/nanosecond timers are now actually possible for amounts less than 10 microseconds.

Commit: 47d2437

Updated telepearl plugin to use hmProcessTargets for the hm_telepearl command

Commit: 47dfccd

Updated nbtmap.h villager_shops plugin is more stable Ported telepearl plugin from master branch to dev-1.13 skulldrop plugin now has a command to give yourself a player's head Added new plugin warp_points

Commit: 47d2437

Added a new library nbtmap.h:

• Fast and easy NBT parsing header-only library
• Very small, has no error checking at all. Assumes all NBT is valid and works 100% with all valid NBT
• No type checks or conversions, everything is treated as a string
• Ideal for parsing data get requests from the server, but can also be used to build NBT
• See ./src/plugins/villager_shops.cpp for example usage

API Changes:

• Added a new event onPluginsLoaded triggers before server startup after every extension and plugin has finished loading
• Added hmResolveFlag() and hmResolveFlags() both return the integer representation of a flag string

Plugin Changes:

• baseplayerinfo.cpp now uses nbtmap.h
• New plugin: villager_shops:
• • Create survival shops using villagers
• • Create and restock shops from a chest
• • All payments made in the shop are tracked and given to the shop owner

Commit: ad883f7

Updated halfMod API to v0.2.4 Updated halfMod Engine to v0.1.3 Updated halfShell to v0.3.3 Full changelog: https://github.com/nigelSaysHesHappy/halfMod/blob/1.13-dev/changelog.txt

halfMod API Changes:

• Added Console Variables (aka ConVars or cvars)
• • Defined by plugins or extensions, removed when the defining plugin is unloaded
• • Act as a global variable that can be changed through the hm_cvar command
• • Simplifies creating customizable variables or settings for plugins and extensions
• • Can be linked to gamerules
• • Can have default, min, and max value rules
• • Stored as a string, converted to float for min/max boundaries
• • Can be retrieved/stored as string/bool/int/float
• • Can be hooked to trigger a function when the value has changed (by whatever means)
• • There are flags that can be OR'd together to control the cvar's behaviour:
• • • FCVAR_NOTIFY = Clients are notified of changes
• • • FCVAR_CONSTANT = The cvar is assigned to the default value and cannot be changed
• • • FCVAR_READONLY = Only internal methods will be able to change the value, gamerule will be able to change it, but hm_cvar will not
• • • FCVAR_GAMERULE = The cvar is tied to a gamerule of the same name
• • If linked to a gamerule (with min/max values defined) and set out of bounds, the value will instantly be reverted back within bounds
• • • This allows a server owner to set the bounds of gamerules so admins cannot change them to unwanted values
• • For non-gamerule cvars, they simply will not be allowed to change out of bounds
• • All plugins and extensions have access to all defined cvars
• • • Multiple plugins/extensions can hook the same cvar
• • • When creating a new cvar, if it already exists a pointer to it is returned
• Removed some restrictions on extensions making them more flexible
• • Extensions can now create timers and hook patterns
• Added high resolution timers
• • Timer syntax has changed slightly:
• • • int createTimer(std::string name, long interval, std::string function, std::string args = "", short type = SECONDS);
• • • • Type will default to SECONDS. Allowed options:
• • • • • SECONDS, MILLISECONDS, MICROSECONDS, or NANOSECONDS
• • • • interval will be the number of type to wait before triggering
• • • • Existing timers will work exactly the same without any needed modification
• Added new events:
• • onGamerule:
• • • Triggers when a gamerule is set or queried
• • • The smatch list is as follows:
• • • • 1 = gamerule, 2 = "now" (has changed) or "currently" (query), 3 = value
• • onGlobalMessage:
• • • Triggers when the hmSendMessageAll command is used from anywhere, after the message is sent
• • • The smatch list is just: 1 = message
• • onPrintMessage:
• • • Triggers when any somewhat private or server related message is printed to the console
• • • Follows --debug --quiet --verbose rules
• • • The smatch list is just: 1 = message
• • onConsoleReceive:
• • • Triggers every time any message is received from the server that does NOT match any HM_BLOCK_OUTPUT filters
• • • Basically if the server message will be printed to the console, this will trigger
• • • The smatch list is just: 0 = message
• Added function: hmProcessTargetsPtr
• • Functions exactly the same as hmProcessTargets, except the target list is populated with pointers to the matching hmPlayer structs
• • • Allows finding and directly modifying stored player data
• Added function overloads for every function that has a string function argument
• • Now they also accept function pointers instead of the string

halfMod Engine Changes:

• Added three new internal commands:
• • hm_cvar [value]
• • • View and set the values of ConVars
• • hm_cvarinfo [page#] | hm_cvarinfo [page#]
• • • View and search all ConVars
• • • Works similarly to the hm_info command, but without being able to limit to a specific plugin
• • hm_resetcvar
• • • Reset a ConVar to its default value
• hm_info now displays internal commands as well
• • Using hm_info plugin internal will display only internal commands
• Offline players are now allowed to run commands as themself
• • Used with hs raw [99:99:99] [Server thread/INFO]: <nigel> !kick %all
• • Any command feedback to the user is printed to the console instead
• Config file can now be partially used in conjunction with the command line arguments
• By default all logging options are enabled defaultly
• • Added command line switches to disable specific logging:
• • • --log-off, --log-bans-off, --log-kicks-off, --log-op-off, --log-whitelist-off
• • • The old --log-+ switches still exist, useful for example: --log-off --log-bans
• Now halfMod will disconnect from the server if it receives an invalid handshake

Technical Changes:

• Now uses clang++ to compile instead of g++
• • This fixes a crash caused by a regex overflow
• • All compile scripts have been updated. Be sure to install clang!
• Fixed a rare bug with str_tok miscalculating token sizes
• Tons of optimizations for the API, halfMod engine, and halfShell

halfMod Plugin Changes:

• New plugin advbans:
• • Ban IP and UUID ranges
• • • Loosely based off IRC's Ban-Lines like k-line and z-line
• • • Piggy backs off admincmds's offline timed unban system
• • • • If the server is offline when a ban should expire, without the admincmds plugin, they will not be lifted
• • • • Timed bans while the server is online do not rely on admincmds
• • Commands:
• • • hm_bline <pattern (username:uuid@ip)> [minutes, 0 = permanent] [reason]
• • • • Ban a username:uuid@ip mask
• • • • • When a user connects that matches the pattern, they will be banned for minutes
• • • hm_unbline <pattern (username:uuid@ip)>
• • • • Remove a bline pattern, but not any of the bans it created
• • • hm_kline <pattern (username:uuid@ip)> [minutes, 0 = permanent] [reason]
• • • • Auto kick a username:uuid@ip mask
• • • • • When a user connects that matches the pattern, they will be kicked
• • • hm_unkline <pattern (username:uuid@ip)>
• • • • Remove a kline pattern
• New plugin cvar_rules:
• • Define ConVars for configured gamerules
• • Gamerules are configured in "./halfMod/config/gamerules.conf"
• New plugin flags:
• • Dynamically set users flags during the current session
• New plugin log:
• • User Defined Personal and Global Logs
• New plugin motd:
• • Welcome Message of the Day
• • Displays a configurable json or txt file to players on joining the server
• • • If using txt file %identifiers (%all, %me, %r, etc...) are evaluated
• • Can also execute configured commands when players join
• New plugin urlchat:
• • Clickable URL's in chat
• • Sending a url into chat will be converted into a clickable json link
• • If the url points to a page containing a title/header, that text will be used as the link text instead of the url itself
• • • Follows all redirects
• • Requires curl. Not the dev package, just that curl itself be installed
• New plugin skulldrop:
• • Players drop their head when they die
• • If cvar drop_head is true, players drop their head on death
• • • Default: true
• Changed admincmds:
• • Added a cvar default_ban_time:
• • • Default number of minutes to ban someone for if no value is provided to the hm_ban command
• • • Default: 0 (permenant)
• • Fixed hm_noclip for 1.13 changes
• Changed disco:
• • Added a cvar disco_time:
• • • Change the tempo of the disco! In fractional seconds
• • • Default: 1.0

• • Now the rate is in milliseconds (disco_time+1000)
• Changed geoip:
• • Added a cvar geoip_onconnect:
• • • Display player's GeoIP location info when connecting
• • • Default: false
• • Now stores the geoip lookup in the player's data struct, displays on hm_whois calls
• Changed reservedslots:
• • Added a cvar reserved_slots:
• • • Set the number of reserved slots
• • • Default: 1
• • Removed hm_reservedslots command
• Changed vote:

• • Added a cvar vote_time_add:
• • • Seconds to add to the timeout each time a vote is cast
• • • Default: 60
• • Fixed a bug with hm_voterun being weird with certain parameters

Added new secret features! (Because I can't remember everything else that has been changed/added)
