Fix feed.json when there are multiple screenshots

[prateekmedia]

Let's say I want AppImage Pool app screenshot's, now the problem is that I have added 4 screenshot in appdata xml but appimagehub's feed.json shows 1, it is for all appimage in feed.json.

Can you add code to fetch all screenshots instead of only one?

The AppStream spec is from
https://freedesktop.org/software/appstream/docs/chap-Quickstart.html#qsr-app-screenshots-info
so it is not from the AppImage developers.

For appimage.github.io we are currently using only one screenshot.

@probonopd Yeah I wanted to focus on the second sentence, if an app has more screenshot then how we can use it, Like I want to use it in my AppImage Pool app store.

Can you help me generate a custom feed.json that has it, or how are you fetching posts in feed.json file https://github.com/AppImage/appimage.github.io/blob/master/feed.json

https://appimage.github.io/feed.json already contains them:

        {
        "name": "AppImagePool",
    
        "description": "<p>Simple AppImageHub Client</p>\n<p>Top Features:</p>\n<ul>\n  <li>FLOSS and non profit app</li>\n  <li>Simple categories</li>\n  <li>Download from github directly, no extra-server involved</li>\n  <li>Upgrade and Downgrade appimages easily</li>\n  <li>Version History and multi download support</li>\n  <li>Fast downloader</li>\n</ul>\n<p>Note : Some features are not implemented yet.</p>",
    
        "categories": ["Utility"],
        "authors" : [{"name":"prateekmedia","url":"https://github.com/prateekmedia"}],
        "license" : "GPL-3.0-only",
        "links": [{"type":"GitHub","url":"prateekmedia/appimagepool"},{"type":"Download","url":"https://github.com/prateekmedia/appimagepool/releases"}],
        "icons": ["AppImagePool/icons/scalable/appimagepool.svg"],
        "screenshots" : ["https://github.com/prateekmedia/appimagepool/blob/main/assets/screenshot/home.jpg?raw=true
https://github.com/prateekmedia/appimagepool/blob/main/assets/screenshot/category.jpg?raw=true
https://github.com/prateekmedia/appimagepool/blob/main/assets/screenshot/app.jpg?raw=true
https://github.com/prateekmedia/appimagepool/blob/main/assets/screenshot/search.jpg?raw=true"]
        },

but indeed it looks like they are just concatenated together without spaces between them?

@probonopd Oh sorry and thanks, can you tell me from where are you fetching posts in feed.json.

[probonopd]

Jekyll generates the feed using https://github.com/AppImage/appimage.github.io/blob/81ce3b56a988f1b1185f138cb2fc3f96ce030f6f/feed.json.

Do you know how to change

appimage.github.io/feed.json

Line 35 in 81ce3b5

"screenshots" : {{ post.screenshots | jsonify }}

so that the different screenshots do not simply get concatenated? Jekyll jsonify doesn't seem to do the right thing here?

[prateekmedia]

Yeah they don't have commas between them and are concatenated together.

Sadly I am no expert in this.
