Scrap a channel and find the Roll number from the message and username with tag and put that in the google spreadsheet if not already present

[piyushchauhan]

For example see the messages in #intro channel of Cassiopeia server at https://discord.gg/NYHj58M
Steps:

• Get the channel where !scrap rolls command is sent.
• Go to that channel and get the past messages and check if it contains any roll number or not (use regular expression to find the roll number). If no roll number is found in that message move next message.
• Store the username with tag in the spreadsheet matching to that corresponding roll number. If that roll number does not exist then send the message in that channel saying that roll number is not in the database and mention the moderator so that he can register his name also in the database.
• Get the username with tag of the author from the message.

Column order in the spreadsheet

Discord username tag	Real Name	Roll Number	email	House	Comments

I would like to work on this issue.

[piyushchauhan]

@Darshilp326 Ok I am assigning it to you. You can start working on it.

[piyushchauhan]

Make a new command for this task in new file. !scrap rolls

[piyushchauhan]

One possibility to solve this. @Darshilp326

1. get the list of all the people who are accessible to the channel in which !scrap rolls was sent.
2. get all the messages from each person that was sent in that chennel.
3. Perform the roll number reqular expression query on each message.

@piyushchauhan For 2nd step we need to fetch messages which will lead to older problem only.

Most probably there won't be more than 100 msgs sent by a user in that channel. So that will work practically.

Anyways later on we can add a moderation to the channel that if the person who messaged is in the channel is already in the spreadsheet database then we can delete that message. So that it won't cause much over head in future.

[Darshilp326]

@piyushchauhan there is no inbuilt function for finding a specific user's message. We need to fetch all messages of that channel and then find manually by checking that message's author id and our user's id.

[Darshilp326]

@piyushchauhan one solution can be for every message we need to check if it contains roll no. But for this we don't need command !scrap-rolls.

If this is possible through Discrod.js then our job is done.

@Darshilp326 Have you tried this? https://discordjs.guide/popular-topics/collectors.html#basic-message-collector

[piyushchauhan]

Have you made the Regex for roll number?

[Darshilp326]

^\d{4}[a-z]{2,}\d{1,3}$ regex

Message collector will work ! Actually without that also if we check every message then it is similar to message collector only.

[piyushchauhan]

^\d{4}[a-z]{2,}\d{1,3}$ regex

https://regex101.com/r/ck8jKo/21

\d{4}[a-z]{2}\d{2}

This will be a better one. Always consider multiline strings when building regex

Ok i will take this but i have assumed that in one message we will be getting only one roll number
