Options: edit link and dates

Two lines at the foot of a page: a link to its source file on the repository host, with editLink, and the date of the last change, with lastUpdated.

The keys are documented in the configuration reference, under editLink and lastUpdated. This page shows them in use and says what they change. How the address is built, and why a shallow clone shows no dates, is in Edit this page and the date of the last change.

The link to the file

{
  "site": {
    "name": "Acme",
    "description": "Acme runs background jobs for your app.",
    "url": "https://acme.example",
    "repository": "https://github.com/acme/acme"
  },
  "editLink": {
    "enabled": true,
    "branch": "trunk"
  }
}

The example has site.repository too, because the link is built from it. For the page docs/guide.md the foot of the page gets a link called Edit this page, with this address:

https://github.com/acme/acme/edit/trunk/docs/guide.md

• enabled turns the link on. It is on the pages of the collections and on the Changelog page. It is not on the home page, the 404 page or the index page of a collection, which have no source file.
• branch is the branch in the address. Without it the address uses main.
• host is for a repository on a domain that the kit does not know. The next example is a GitLab that you run yourself:

{
  "site": {
    "name": "Acme",
    "description": "Acme runs background jobs for your app.",
    "url": "https://acme.example",
    "repository": "https://git.acme.example/docs/acme"
  },
  "editLink": {
    "enabled": true,
    "host": "gitlab"
  }
}

The address of the same page is now https://git.acme.example/docs/acme/-/edit/main/docs/guide.md. With the host bitbucket it would be https://git.acme.example/docs/acme/src/main/docs/guide.md?mode=edit. Without host, a repository on a domain the kit does not know gets no link, and the build prints editLink is on, but the host of https://git.acme.example/docs/acme is not known. Set editLink.host to "github", "gitlab", "bitbucket", or turn editLink off.

The date of the last change

{
  "lastUpdated": { "enabled": true }
}

Each page that has a source file gets a line with the date of the last commit that changed that file, as <time datetime="2026-10-30">30 October 2026</time>. The month is written out, so 03/04 is never read two ways. Without the key there is no date, and the key is independent of editLink: one can be on without the other.
