Yes, I forgot to mention this, the existing links and manually entered links via markdown or html or pasted directly into composer are not modified.
Only the specific ‘words’ in the cooked html of the post are linkified on the fly by the client’s browser (there is absolutely no modification of the raw post).
Ah, thank you, this has been the background of all my questions in this thread. Maybe I should have been more explicit.
I agree. It’s important to keep in mind that this is kind of a bonus feature. If people take the time to link to something specific, then great. (If I’m understanding correctly) Otherwise it’s a help to the readers of the post even if the person posting doesn’t make the extra effort to put in the link.
Thanks so much @musiko for working on this.
I love that it makes clear (visually) that these are automated links and not user-supplied links. A+
Ah, it actually wasn’t clear to me! I think dotted underlines usually indicate a definition is available if you hover, eh? From the standpoint of a general reader of posts, will it really matter if they were auto linked or not? I guess my point is that for that general reader, they would have no idea that dotted links were auto generated or even what auto generated links were at all.
I think for usability even the auto generated links should be styled in the same way as regular links, possibly with the addition of dotted underline.
As a side note, I’m an Accessibility Dark Theme user so for me the links are usually yellow, which I think is great. But to see what was going on, I tried out the Accessibility Light Theme and I find the gray color of the regular links to be awful. I don’t see how gray text could be considered accessible at all. Usually it indicates something is unavailable or possibly a link visited. I find it really hard to see where the links are. But I guess if no one else has complained then it’s not an issue? If it was really going to be an accessible theme, the links should be underlined for maximum usability. Anyway, just my $0.2.
@musiko, Is this live on the site now? Looks like it is. Amazing!
Edit: Just for completeness, I tried the legacy theme and it looks like auto generated and regular links are both styled the same. I’d also note that the very thin yellow underline on links doesn’t seem great for accessibility either.
Once an auto link is quoted, it appears like a regular link, which I think is just fine. 
This just in—all major collections are now supported. No need to copy and paste links to the suttas from browser any more, simply put an abbreviation to the specific sutta in the post and let Discourse do its magic (may require browser refresh once).
It’s best to use standard abbreviations: DN, MN, SN, AN, Dhp, Iti, Snp, Thag, Thig and Ud for consistency, but upper, proper and lowercase all work.

Great work. It’s really impressive. This is a great enhancement to the forum.
BTW, for me some of the citations linked and some didn’t, but then when I did a hard refresh they all did.
Some omissions were fixed, all sutas should now be automatically linkified (requires browser refresh). Here’s a list of all supported collections with corresponding last sutta IDs:

should work now (requires browser refresh).
It linkafies but sends me to a malformed url. The : should be replaced with a . in the URL 
I have also seen the : used in the AN, Ud and Snp. Would be nice to accommodate that too.
Unfortunately, the : as an optional separator proved to be more tricky than it looked. I’m removing this option for now (please refresh browser) and will investigate further.
You would also want to replace the SN rule for your tool with the updated one here Citation Link Up tool 🔧 to turn citations into links for a block of text - #7 by musiko
Sorry, I’m having a little bit of a hard time tracking… is the : separator problematic for regex in general, or just for the Discourse implementation?
It’s the same regex rule, so both (the problem is not the engine but the rule itself, which I’ll try and fix).
Currently the rule is not capturing the left and the right number separately and this prevents linking to the correct id.
These should all work now (for legacy purposes only!—use dot notation for all new entries to D&D), with a caveat: legacy notation uses simplified rules which in some cases match non-existent sutta IDs to invalid SC links!
Thanks! So, to be clear, If I do do a AN 4:9 it’ll work, you just recommend using dots (An 4.9) instead? Or you won’t support colons going forward?
Colon rule will map all existing entries on D&D. While it will also work for new entries I recommend using dot notation as it is more precise (it will not map invalid SC links as opposed to the colon rule).
This is so great! It’s fun to see it all over the site now.
Just out of curiosity, could you share an example of what doesn’t link right with a colon?
Basically anything that has the last number larger than the last existing sutta ID in that chapter (see table Automatically linking up citations to suttas on D&D - #30 by musiko).
For example:
Dot notation doesn’t allow invalid IDs:
