/ sorry for cross-posting
On a few first wikis, you can now highlight pairs of brackets in
wikitext. For this to work, you need to turn on the syntax highlighting
feature, which is part of the 2010 and 2017 wikitext editors. By placing
your cursor next to or within a set of brackets, you can then match round,
square and curly brackets. For more information about this feature please
visit its project page.
Deployment to other wikis is planned for later this year. If your wiki
community wants to get bracket matching now, please contact me.
This change has been implemented by the Technical Wishes team who is
currently working on several projects within the focus area "Make working
with templates easier". Other projects in this focus area, including
those for the Visual Editor, are in the making.
Many thanks to all who have contributed to the realization of this project
through comments, interviews and more. Feedback is, as always, welcome on
the project's talk page.
