I can name an article "Learn the basics: Get started with Firefox" but article title links to don't work. Using [[Learn the basics: Get started with Firefox]] should work but it just produces the unlinked text "[[Learn the basics: Get started with Firefox]]"
Probably a parser bug? Adding to next sprint for now.

Tweaking the scope of this: We're going to look into this for at most a day. If we figure it out, yay! If it turns out to be complex or not possible to fix, we'll talk about it in a stand-up.
I'm going to look into this today and see where the rabbit hole goes.

Here's the deal. A colon in a title has syntactic meaning to the parser. It's what the parser uses to denote internal namespaces. That's how Template:, Video:, Include:, and all that works. The problem here is that the article is titled "Learn the basics: Get started with Firefox", but when you put that in a link like this: [[Learn the basics: Get started with Firefox]] that gets parsed into two parts: namespace: Learn the basics title: Get started with Firefox and there's nothing that handles the "Learn the basics" namespace in our system. Ipso facto, it doesn't work and produces no link. If you tweak the link to something like [[Learn the basics: Get started with Firefox|Learn the basics: Get started with Firefox]], then it does produce a link, but the link goes to the "create a new page!" page and not the page you were trying to link to. I talked with Erik to confirm my prognosis and he says it's worth trying to fake out the parser using urlencoded colon. So I tried that and wasn't able to get it to work putting the urlencoded colon (&58;) in either the article title or the link. It keeps getting converted back to a colon. At this point, I think it's either not possible to fix this within the constraints of our requirements and how wikimarkup gets parsed, or if it is possible, it'll be a serious project. I don't think there are other options. I think we should close this out as WONTFIX and make a note near the title field that you shouldn't use colons. Any thoughts?
Ok. Just as I hit "Save Changes", it occurred to me that I can make this work if we use COLON instead of : in the links because this is specifically a link-parsing problem. WARNING: If you're not into hacktastic solutions, look no further! I can tweak the link handling bit of the sumo parser so that it tries the article and if it doesn't exist and has COLON in the link, then it replaces COLON with : and tries again. So you'd be creating article links like this: [Learn the basicsCOLON Get started with Firefox]] I can make that work. Is that too hacktastic?

To clarify, this isn't an issue with the article title--this is just an issue with the link. So the title of the article as seen in the kb/new form and other forms and on the site and everywhere else is "Learn the basics: Get started with Firefox". But to use it in a link, you have to replace : with COLON so it looks like "[[Learn the basicsCOLON Get started with Firefox]]". Do localized articles also go through and localize all the internal links?
(In reply to Will Kahn-Greene [:willkg] from comment #7) > > Do localized articles also go through and localize all the internal links? No, not normally. Here's a section of an Italian article: =Organizzare i segnalibri= I seguenti articoli spiegano come ordinare e organizzare i propri segnalibri: * [[Sorting bookmarks]] * [[Bookmark folders]] * [[Deleting bookmarks]] I guess my question is that if you have something like [[CookiesCOLON Chocolate chip, Oatmeal raisin and more]] will that display as "Cookies: al cioccolato, farina d'avena uva passa e più" in an Italian article? Another issue I thought of is that the new forum article link maker thing would need to know to change : to COLON and we'd have to make sure people knew that when copying the title of an article and making it a link you'll have to manually change : to COLON.
(In reply to Verdi from comment #8) > we'd have to make sure people > knew that when copying the title of an article and making it a link you'll > have to manually change : to COLON. How critical are colons in titles? Could they be replaced with hyphens? Step back and read that with less context. That sounds awful. MediaWiki itself handles colons in titles, c.f. http://en.wikipedia.org/wiki/Star_Wars_Episode_VI:_Return_of_the_Jedi Maybe our current parser (py-wikimarkup) could be pretty-easily extended to see if namespace is a registered namespace and, if not, rejoin it to the rest of the title? > def split_title(page): > if ':' in page: > namespace, _, title = page.partition(':') > else: > namespace, title = None, page > if namespace and namespace not in self.registered_namespaces: > namespace, title = None, ':'.join((namespace, title)) > return (namespace, title) There's probably a less-hacky way to do that, but let's keep the hacky crap in the code, and not in the user experience, if we have to have hacky crap at all.

After what verdi has said, I'm -1 on the hack--it touches too many people. I'm pretty sure there is no pretty-easily extended way to do this. The docs suggest that: https://github.com/dcramer/py-wikimarkup#adding-internal-links The py-wikimarkup project is pretty dead, so we could fork it and maintain our own fork. But this parser doesn't have many tests and we don't have many tests for the parser, either, so fundamental changes to the parser aren't without risk. I'll look into it more today.
We never used dcramer's fork, always Paul's: https://github.com/pcraciunoiu/py-wikimarkup and, even though he left Mozilla, he's been great about merging pull reqs. Also I still have commit there.
We are currently making due with hyphens in titles instead of colons, which is fine. I don't think it's that big of deal to waste more time on. I'm ok with not fixing this now and looking into it some other time.

I retroactively created a research bug for figuring out the deal because there's some good information in here should someone want to fix this in the future. So I'm reopening this one, bumping it out of the sprint (to be replaced by the research bug), and unassigning myself.

This is still an issue. I edited the metadata today for three four articles, to remove the colon from the title. See:
https://support.mozilla.org/en-US/kb/premium-subscriber-faq/discuss/11679
https://support.mozilla.org/en-US/kb/pocket-premium-suggested-tags/discuss/11678

https://support.mozilla.org/en-US/kb/pocket-premium-full-text-search/discuss/11676

If this problem can't be solved, can we at least show a warning when we create a new article (or edit the metadata for an existing article) when the proposed title includes a colon?

Another new article was just approved with a colon in the title. See:

Type: task → defect

Still an issue. This newly approved article includes a colon in the title:
Contributor Policy: Usage of Generative AI (e.g., ChatGPT)

This came up again, with a new article created by Lucas: Firefox blocked by macOS 15 Sequoia firewall: What you need to know
See https://support.mozilla.org/en-US/kb/firefox-blocked-macos-15-sequoia-firewall-what-you/history

If this bug can't be fixed, can there at least be a message, such as "The article title includes a colon, which prevents wikilinks" when the title is entered in the Create a new Knowledge Base article page, or when you edit the article metadata to change the title for an existing article?

Just updated the article's title to "Firefox blocked by macOS 15 Sequoia firewall - What you need to know". Thanks for the flag, Alice.

Flags: needinfo?(lsiebert)

This came up again, for an article originally titled "Placeholder Bug 1929565". The title was just changed to "Firefox connection upgrades: HTTP to HTTPS", which includes a colon. I updated the article title to "Firefox connection upgrades - HTTP to HTTPS".
See https://support.mozilla.org/en-US/kb/https-upgrades/discuss/12772 and https://support.mozilla.org/en-US/kb/https-upgrades/links

This came up again, for the new article "How it works: Firefox Weather" https://support.mozilla.org/en-US/kb/how-it-works-firefox-weather (I added a comment to the related bug 1944582 asking to change the title).
