New requirements for user signatures/ja

利用者の署名を取り入れるウィキは多く、それぞれ固有の要件を設けています. 編集機能チームでは署名要件をコード化してウィキペディアのソフトウェアに埋め込むという案につき、 皆さんからのご意見を募集中です. この措置が実現すると、トークページで特定のコメントへの返信することが楽になり、また他のツールの利便性も高まります.

提案の詳細とその理由は下記でご紹介します：

背景情報：なぜこれを変更？
ウィキメディアのプロジェクト群ならびに利用者グループのボランティア参加者20名とウィキメディア財団職員は2019年、トークページの協議に参加ました. これはオンウィキのコミュニケーションにもっと適したツールとは何にか、定義する努力の一環です.

One of the outcomes of this consultation was a request for an easier way to reply to specific comments on talk pages.

In order for this feature to work well, the software needs signatures to be "machine-readable", so it can reliably detect users' comments and allow replying to them.

The trouble is, while many wikis already have the necessary signature requirements in place, these requirements are not included in the software itself. This increases the chances someone will set a signature that breaks the wiki's conventions and potentially, make it more difficult for people to participate in conversations.

This additional consistency in the format of signatures would improve existing features, like "mention" notifications, which are only sent if the signature can be detected in your edit.

Proposal: signature validation requirements
The three proposed checks are described in this section. These would be applied to user signatures in Preferences when a user saves a modified signature. Under the Editing team's proposal, existing signatures will *NOT* be affected.

Disallow some invalid HTML and other Linter errors
Most importantly, this change would disallow unclosed formatting tags, like or the corresponding wikitext markup, , without a matching closing tag (in this case,  or  , respectively). Signatures containing invalid markup can affect the entire discussion page, when the formatting continues into subsequent comments.

The check would also identify misnested tags, like  (either both of the , or both of the  , tags should be on the outside), and stripped tags, which are closing tags without a corresponding opening tag (the opposite of the "unclosed formatting tag" listed above).

Signatures that contain some less critical problems would also be disallowed, e.g., obsolete HTML tags like  and . While these do not cause immediate issues, doing this would prevent the spread of obsolete code to new wiki pages, which is an annoyance for editors cleaning up Linter errors.

A full list of syntax features that would not be allowed, along with links to pages that explain how to update or fix code with Linter errors, is available at Help:Extension:Linter#Documentation of lint issues.

Unclosed formatting tags were already supposed to be prevented by the software, but due to limitations of the current wikitext parser, this worked only in some cases. A more robust solution has become possible thanks to Parsoid.

Require a link to user page, talk page or contributions
Various tools don't work correctly when a signature does not contain at least one of the following links: a link to the user's user page, user talk page, or contributions page. For example, "mention" notifications are not sent, and forthcoming DiscussionTools will not allow replying to comments with these invalid signatures. Gadgets and other tools that interact with signatures also may not work as expected.

This requirement has been present for a long time in many Wikimedia wikis' policies, but it has not been enforced by the MediaWiki software.

Disallow "nested" substitution in signature
Some use of subst: markup and tildes would also be disallowed in signatures. Previously, it was possible to use these features to set a signature that would cause a subsequent editor's name to be placed on your comments. All forms of signature forgery have long been banned by policy at the larger wikis, and this type of forgery will now be prevented in software. Simple subst: markup is still allowed.

What would happen to existing signatures?
Any existing signatures that would become invalid under the new rules are still allowed (grandfathered in). When viewing your preferences, you would see a warning message about this, and if you try to change the signature, the new one must be valid. But if you don't change it, the old invalid signature will continue to be used when you sign, and you'll be able to change your other preferences without affecting it.

We're looking for feedback as to whether you would like existing invalid signatures to be disallowed. If invalid signatures are disallowed, the default signature would be inserted when affected users sign their comments, until they correct their personalized signatures.

When might these changes take place?
Please comment before 31 March 2020. The Editing team will make decisions about this project in early April. The results will be posted on the talk page.

If no obstacles are identified, this change would happen no earlier than April 2020. This date could be pushed back if the team needs to implement significant changes as a result of your feedback.

How will we know what changes are happening?
We'll include another notice in Tech/News when this change is about to be deployed.

What might the signature validation errors look like?
The HTML/lint errors include links to existing documentation about lint errors, such as Help:Extension:Linter/missing-end-tag, and a button to highlight the problematic part of the signature.

The required link errors include example wikitext syntax to use.
