[INACTIVE][CHAT] RegexFilter v1.05 - Regular expression chat filter [432-860]

RegexFilter - Regular Expression chat filter
Version: v1.05

This plugin uses the power of Regular Expressions to filter anything you want from chat. Matching messages can be rewritten, logged and blocked, depending on the rules you define. Stop yourself from accidently sending those embarrasing .commands to chat. Warn users who use bad language and even turn their profanities into harmless language.

This plugin comes with a default setup that effectively replaces my dotFilter and 7filter plugins, which will no longer be maintained.

Features:

• Command typos beginning with certain characters can be stopped (like . and 7)
• Optionally recover those typos and execute the command as intended
• Define your own macros or command aliases
• Simple but powerful configuration with built-in debugging
• Each regular expression is compiled only once => very fast
• Supports config reload with "/regex reload"
• Permissions aware, rules may apply to players, groups or permission nodes
• Automatically kick players
• Still no cake

• Optionally create the file "plugins/RegexPlugin/rules.txt" and edit

Configuration:

Code:

# Each rule must have one 'match' statement and atleast one 'then' statement
# match <regular expression>
# ignore user|group [space separated list]
# ignore permission [node]
# require user|group [space separated list]
# require permission [node]
# then replace <string>|warn [<string>]|log|deny|debug|kick|abort

# Example 1:
match f+u+c+k+
then replace cluck
then warn Watch your language please
then log

# Example 2:
match dick
then replace duck

# Emulate DotFilter
match ^\.[a-z]+
then warn
then deny

# Emulate 7Filter
match ^7[a-z]+
then warn
then deny

# Quietly turn "(command" into "/command"
match ^\((?=[a-z]+)
then replace
then command

Please do NOT post questions here about how to write regular expressions, there are thousands of web sites discussing this topic. Google is your friend. The plugin uses java.util.regex and is CASE_INSENSITIVE. It is NOT possible to use parens to capture substrings to be used with replace. ALL matching rules are applied in the order they appear before any action is taken.

 

Ah, thank you for the feedback. I will have a look at it anyway, since I think it still uses some deprecated calls to Permissions that may go away soon.

 

Does this still work? Its on the inactive board for such long time
Any news on this?

 

It still works perfectly but I don't know if anyone else beside myself is actually using it...?

 

I can move it back, but please update to latest RB (currently 670)

 

Now please test it on latest RB (currently 674).

 

Confirmed to work with 733. As long as the chat API doesn't change it should be fairly robust.

 

#here's one i use for words with 3 or more capital letters:

match ^.*(\p{L}*\p{P}*\p{Lu}){3}\p{L}*\p{P}*.*$
then warn NO CAPS!!!
then replace
then command warp chatrules

#and to trim repeated characters to 2 repeats maximum:

match (.)\1\1+
then replace

btw... thanks for the plugin... if you would have waited one day longer, i was planning on doing this :-P

#replace nazi with barbie
match \b(\S*?)(?:N|n)\p{P}*(?:A|a)\p{P}*(?:Z|z)\p{P}*(?:I|i)(\S*?)\b
then replace barbie
then log

#replace IP addresses with 'terrible server' (stops advertising of other servers)
match \b\d{1,3}+\p{P}*\d{1,3}+\p{P}*\d{1,3}+\p{P}*\d{1,3}+\b
then replace terrible server
then log

LOL

 

You should add all caps filters within this.

 

@FloydATC Thanks for this plugin. I actually have something I can apply my learning of regular expressions to.

Edit: Will you add the ability to match against actions (the /me command)?

The first thing I'm doing is fixing some of the common annoyances I see in chat.. such as plz/pls/plx/plox/pl0x. It's not perfect, and I'm still working on it, but so far I have: pl[zsx]|pl[o0]x|/gi .. some of my players already love it

 

Interfering with other plugins' commands? It's not something I'm about to try any time soon, sorry...

 

That's fine, no big deal

What about the ability to apply a filter to only one player, and the reverse.. apply the filter to everyone but one player?

 

FloydATC,
any possibility of getting a 'then finish' or something? so the rest of the rules are ignored?

 

Love it!

The regex is too much for me to sit down and read... but I can do the basics which is what I need. Thanks!

 

This is something I've been wanting to do, yes. It will be optional so if Permissions.jar is not available then such config statements will generate a warning at load time and then get silently ignored.

Should be fairly easy to implement. Combining this with Permissions makes a lot of sense.

Here's what I'm thinking... (WARNING: The final implementation may be different!)

Code:

ignore user <usernames>            Skip current rule if username matches
ignore group <groupnames>        Skip current rule if groupname matches
ignore permission <permission_node>    Skip current rule if user has permission

require user <usernames>        Skip current rule if username does not match
require group <groupnames>        Skip current rule if groupname does not match
require permission <permission_node>    Skip current rule if user does not have permission

then finish                Abort ruleset processing if this rule matches

(update: fixed copy/paste error)

This would allow rules such as:

Code:

match ^\!test
require group admins
then finish

 

that would be excellent

 

Great Plugin, thank you!

Edit: This works perfectly on latest craft bukkit (766)

 

That's weird, my post was deleted. Is there a way to edit out glass and hello?

 

Can you PLEASE add a feature that will kick, ban, and/or mute players who use a censored word?

 

Kicking is easy, banning and muting will have to wait for now.

Version 1.05 has been posted, with the following new features:

• ignore user <names>
• ignore group <names>
• ignore permission <node>
• require user <names>
• require group <names>
• require permission <node>
• then abort
• then kick

Note:

• The "group" and "permission" checks will not be available unless the Permissions plugin is available.
• Multiple "user" and "group" names must be separated by spaces.
• All names are case-insensitive.

 

Quick question for you. can you have some sort of exact word match thing? For example, I want to ban the use of the word "ass" and "hell" however, nobody can then say, "Can I have some glass?" or "Hello, how are you?" because it sees ass and hell. Can you find a way to add * or "" in them? For example

If word == "ass" then kick
If word == "hell" then kick
If word == *ass* then do nothing
If word == Hell* then do nothing

Hopefully you're understanding what I'm putting down.

 

You really should Google for a good tutorial on regular expressions, because fancy wildcard patterns are what they're all about. The word "ass" is actually a good example of why conventional wildcards (like the ones you find in Windows) are insufficient. Consider the words "glass", "assistant" and "massage". Basically, you only want to match the letters "ass" if they appear as a single word. The regular expression \b (word boundary) fits the bill in most cases, because it picks up on whitespaces, beginning/end of line as well as most punctuation.

Try this:

Code:

match \bass\b
then replace bottom

 

Any idea why this matches "fuck" and overrides the filter I already have in place for this word?

EDIT: Also, how do I specify more than one match on a single rule?
e.g. match hell|damn|fart

 

Exactly like that. http://lmgtfy.com?q=regular+expressions

 

Oh, just learn advanced calculus from a textbook written in greek in 1 day you say? I'm rather certain that learning java (thereby making this moot) would be a lot easier. Just saying. I've struggled and struggled with regexp in the past and have never been able to wrap my head around it.

 

Any progress with adding the ability to mute players who use these bad words?

 

Nasty little bug here...

Yes, but the stack trace points to a "RhinoScriptEngine" in "SpyerAdmin". ECMA is the proper name for "JavaScript", which suggests there may be a problem with one of its configuration files or scripts. To confirm this, see if you still get this problem if you disable RegexFilter.

 

I removed SpyerAdmin after it messed up my server.

 

Download doesnt work.
