Description

One of the nicer features of Rollup is that some errors and warnings contain urls linking to further information. Since the plugin and troubleshooting sections are now part of the website, I used this chance to go through all these links, fix the broken ones and make sure all wiki links now point to the website instead. Once this is released, we can definitely replace the troubleshooting section in the wiki with a link to the website as well.

Kind of an aside, but do you think there's reason enough to use a permalink redirect system (shortlink, or other) for links in code? The thought being that the shortlinks could be updated to redirect to any destination and the code wouldn't have to change (and older releases wouldn't contain bad urls as a result)

Depending on how we would set this up, I think this is a really good idea!

From my experience adjusting the links, one major issue is that changes to the markdown files can change the actual links as those are calculated from the headlines, cf. e.g. my adjustments to the links for the output.exports option.

What we could do is to add a list of short, fixed links to the website that are automatically resolved to the actual links by the server. We could then add a script to the website that is e.g. run on linting that calculates all existing link targets by running the markdown converter and collecting the id attributes. Then we check if all needed targets still exist.

If we manage the forwarding by hand, we could even make sure the short links are at least somewhat memorable.

Ok, re-reading what you wrote, this is more or less what you proposed ;)

[shellscape]

Haha yes exactly

[lukastaegert]

@shellscape I guess there is no reason not to merge this for now, is it? The permalink idea would definitely require a little more work, no reason to have wrong links until then.

Agreed. It's a value add.
