|
||||
- what to do if you delete the original discord message
|
||||
- the user's preferences re: saving content
|
||||
- we don't want to save content without the user's consent, especially since it may persist after they disable the integration
|
||||
- manually adding content for various reasons
|
||||
- maybe a bug prevented something from saving
|
||||
- ryan used to post everything in #projects for some reason
|
||||
|
||||
|
||||
real-time stuff:
|
||||
- on new showcase message
|
||||
- always save the lightweight record
|
||||
- if we have permission, create a snippet
|
||||
- on edit
|
||||
- re-save the lightweight record and content as if it was new
|
||||
- create snippet, unconditionally???? (bug??)
|
||||
- update snippet contents if the edit makes sense
|
||||
- on delete
|
||||
- delete snippet if the user so desires
|
||||
- delete the message records
|
||||
|
||||
|
||||
background stuff:
|
||||
- watch mode
|
||||
- every five seconds
|
||||
- fetch all HMN users with Discord accounts
|
||||
- check if we have message records without content
|
||||
- if so, run a full scrape (no snippets)
|
||||
- every hour
|
||||
- run a full scrape, creating snippets
|
||||
- scrape behavior
|
||||
- look at every message ever in the channel
|
||||
- do exactly what the real-time bot does on new messages (although maybe don't do snippets depending on context)
