Regex help

[dannymichel]

I apologize as im aware that this isn't a help forum, but I really don't know anyone who knows regex.
I was wondering if I can have help with 3 things:
3 separate channels i need to do things in
#channel 1 - delete everything that begins with 'http'
#cannel 2 - delete anything that isn't an image(no text what-so-ever)
#channel 3 - delete anything that isn't an image or starts with 'http'(only links and images allowed - no other text than links)

You should try and play with http://www.regex101.com

Channels 1 and 2 should be pretty easy, but you should keep in mind that any attachment can be posted and seen as having no text. I'll have to check to see if empty messages are something that can be matched, but I'm fairly certain they are. Can you give these a try and then message me on Discord?

1: ^http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+, inclusive. This will only match messages that begin with a URL. Replace the ^ at the beginning with .* to match anywhere in the message.
2: ^$, exclusive. Deletes messages that aren't empty.
3: ^(http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+|$), exclusive. Deletes messages have text but don't start with a URL.

caleb, is recensor able to work per channel instead of per server

[calebj]

It's capable of both.

[skeith]

ah right, I missed that latter optional argument

[dannymichel]

thank you. so it would literally be
.recensor add ^http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+ thisiswhereiputthechannelid ?

[dannymichel]

.recensor add ^(http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*(),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+|$ excl 377913250962210816 and .recensor add ^http[s]?:\/\/(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*(),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+ incl 370169460184580095 doesnt seem to work. do i need to toggle the feature on or something? the bot is admin

[calebj]

I'm not sure what you're appending those numbers for, but they'll probably get discarded. You should also be aware that mods and admins are immune to the filter, in case you're testing with yourself.

[skeith]

@calebj I assume those numbers are channel ID

[calebj]

Ah, right. I forgot the converters supported that.

Since your pattern has no spaces, it should be working. Like I said, you're immune from the filter yourself.

The way I test things like this is with an alt. If regex101 and/or testing in a python interpreter are good, it's probably because you're immune to the filter.

[dannymichel]

I'm testing it by having members test it

[calebj]

@dannymichel Can you DM me a list of example messages you've tried so I can perform local testing?

[dannymichel]

sure where/how would i dm you

[calebj]

Head to this channel for starters. The cog support server is the best place to ask these kinds of questions in general, really.
