Here’s a regex replacement rule that formats the wikilink to an image file in frontmatter correctly by removing the preceding !. It also adds ^ as link caption so that the link isn’t an eyesore.
regex to find:
^(cover:\s*")(!\[\[|\[\[)([^|\]]+)(\|[^\]]*)?(\]\]")$
flags: gm
regex to replace:
$1$2[[$4|^]]"$7
Before:
After:
Note that only the link in the cover property is affected.
I set this up as a custom regex replacement rule in Linter settings > Custom.
I have Linter set up to automatically lint files on save and focused file change, so this rule is applied automatically.
This is useful when working with:
- Bases card view.
- Community plugins that add banners to notes.
- Images localized by Local images plus.
Make sure to back up your vault before running this rule for the whole vault in case of bugs.
