[RSS] Allow arbitrary urls in embed_image and embed_thumbnail

[Griefed]

Heya,

if possible, I would like some documentation/explanation on how the !rss embed image and !rss embed thumbnail commands are to be used in order to add an image to the embed. I'm having trouble setting it to an image so it is included in the message.

What do I need to do in order to add an image/thumbnail to the rss message? After setting !rss embed image <image_url.png> rss tells me that the new tag is available as $<image_url.png> but when adding that to the template, the image isn't displayed.

What am I not understanding here? :D

Cheers,
Griefed

Trying to replace a bot by configuring rss so I can have one less bot on my discord server. Here's an example. Top is what I want to imitate, bottom is the current configuration, where I want to insert embed_image and embed_thumbnail.

I'll have to change how the cog responds to users when adding a tag - naked image urls are not allowed, you must use a tag that is included with the feed, under rss listtags. Usually images can be found under tags like $content_image01 or other sequental content_image numbers if they are present. Multiple people have asked for settable urls instead of tags so I will consider it and close this issue when I have it resolved or if I decide not to support it.

Thanks for getting back to me. Sounds great. Being able to set tags manually would be a dream come true, as it would allow one to setup templates much like the example above.
listtags doesn't include any images, sadly. That's why I was hoping I could set images with embed_image and embed_thumbnail.

Keep up the good work. Stay safe and take care.

The RSS feed itself does not contain any images if you don't have a $content_image01 tag or similar. If this is your feed, you may want to add those. They are scraped from html tags styled <img src= ... >.

608bcae catches your incorrect input and will explain the situation a bit better.

Sweet, thanks!
It appears the problem is on my end. Wordpress' feed doesn't include images, or rather, none that can be used by RSS. The list of available tags for my feed doesn't mention any image whatsoever, so I will have to check whether I can somehow expand my feed with said images, in order for RSS to work with them.
Will need to check whether there's something I can do from my end to provide images. A plugin or something.

I still want to work on allowing arbitrary urls but since I designed RSS to use tags this will take me a bit. The commit with more chatter regarding the input is a stopgap until I have time to figure it out.
