Closes #136.

Summary

  • docs.yaml: on PR builds, run yq against altdoc/quarto_website.yml before altdoc::render_docs() to rewrite three keys:
    • website.repo-urlhttps://github.com/<head_repo_full_name>
    • website.repo-branch<head_ref> (so quarto's "Edit this page" / "View source" land on the right file in the right branch)
    • website.navbar.right[icon == "github"].href<pull_request.html_url> (so the navbar GitHub icon opens the PR conversation page)
  • altdoc/quarto_website.yml: add a short comment next to the three keys so it's not a surprise that they get mutated in CI.
  • Non-PR builds (push to main, releases, workflow_dispatch) leave the YAML alone.

yq is preinstalled on ubuntu-latest, so no extra setup step needed.

Test plan

  • On this PR's preview, the navbar GitHub icon should open https://github.com/d-morrison/rpt/pull/<this PR#>.
  • On any page, "Edit this page" should resolve to https://github.com/<head_repo>/edit/<head_ref>/..., not main.
  • After this PR merges, a build of main should produce a site whose navbar GitHub icon points at the repo root ($ALTDOC_PACKAGE_URL_GITHUB substituted by altdoc), confirming non-PR builds were left untouched.

🤖 Generated with Claude Code

On PR-preview builds, the navbar GitHub icon now opens the PR conversation
page and quarto's "Edit this page" / "View source" actions land on the PR
head branch instead of UCD-SERG/rpt main. Non-PR builds are untouched.

docs.yaml gains a `yq` step before `altdoc::render_docs()` that rewrites
three keys in altdoc/quarto_website.yml: `website.repo-url`,
`website.repo-branch`, and the `website.navbar.right[icon == github].href`.
Sourced from `github.event.pull_request.head.repo.full_name`, `head.ref`,
and `html_url`. yq is preinstalled on ubuntu-latest.

A comment in altdoc/quarto_website.yml flags that those three keys are
mutated in PR builds, so the in-place rewrite isn't a surprise to anyone
reading the YAML cold.

Change applied

The comment in altdoc/quarto_website.yml previously said all three keys are "rewritten in-place", which was misleading because repo-branch doesn't exist in that file — the workflow inserts it dynamically. Updated to:

# On PR-preview builds, .github/workflows/docs.yaml rewrites `repo-url` and
# the navbar GitHub icon's `href` below, and inserts `repo-branch` (absent
# here; added dynamically), so "Edit this page" / "View source" / the navbar
# GitHub link point at the PR branch and PR conversation page, not main.

Code review

.github/workflows/docs.yaml — new step (lines 115–124)

Correctness

  • if: github.event_name == 'pull_request' correctly gates the step so non-PR builds leave the YAML untouched.
  • Values are passed through env: vars and read with strenv(), which avoids shell injection from branch names or PR URLs containing special characters.
  • yq is preinstalled on ubuntu-latest — no extra setup needed.
  • Step is placed before Build site (the altdoc::render_docs() call), so the mutated YAML is picked up at render time. Ordering is correct.
  • repo-url and the navbar href are rewritten (keys already exist); repo-branch is inserted as a new key. All three yq calls work as intended.

Robustness

  • The select(.icon == "github") filter silently matches nothing if no item in navbar.right[] has icon: github, so there's no risk of the step erroring if the YAML structure changes. Worth noting in docs but not a bug.
  • Fork PRs: github.event.pull_request.head.repo.full_name correctly resolves to the forker's repo, so "Edit this page" links will point to the right fork and branch for cross-repo PRs. This is intentional and correct.

Minor observations (no action required)

  • The three yq -i calls could be collapsed into one compound yq expression for a slight speedup, but the current three-liner is easier to read and maintain — fine as-is.
  • repo-url on the main branch still points to https://github.com/UCD-SERG/rpt, which diverges from the current repo owner. That's a pre-existing issue unrelated to this PR.

altdoc/quarto_website.yml — comment (lines 18–21)

After today's fix: clearly distinguishes which keys are rewritten vs. inserted. ✅


Summary

The implementation is correct. The only substantive change needed was the comment clarification, which has been committed and pushed to claude/issue-136-pr-preview-links.

The previous comment said all three keys are "rewritten in-place", but
`repo-branch` does not exist in this file — the workflow inserts it
dynamically on PR-preview builds.

Co-authored-by: Douglas Ezra Morrison <d-morrison@users.noreply.github.com>
If the navbar selector (`.website.navbar.right[] | select(.icon == "github")`)
ever fails to match — e.g. because someone renames the entry or the version
dropdown script later widens its scope — the yq edit silently no-ops and the
preview site keeps pointing at main. Read the three values back after the
rewrites and fail the workflow if any of them isn't what we expected, so the
regression surfaces immediately in CI rather than as a confusing user
experience on the preview.

Also added a comment pinning the step ordering (must run after the version
dropdown generator) to head off subtle future breakage.

Two issues from round 2:
- `yq -i '.website.X = ...'` will *create* X if .website itself has been
  renamed or restructured, so the postcondition check would happily read
  back the value we just wrote into a key quarto ignores. Add a
  precondition pass with `yq -e` that fails the workflow if either
  `.website.repo-url` or the navbar `icon: github` entry is missing
  before we attempt to rewrite anything.
- Replaced the `[ A ] || [ B ] || [ C ]` line-continuation chain with a
  single `[[ A || B || C ]]` to remove the trailing-whitespace footgun.

Fixed "View source" link for man pages

  • Read relevant files and understand root cause
  • Implement fix
  • Commit and push

Root cause

man/calculate_summary.qmd (and all other man-page .qmd files) are generated by altdoc at build time from the corresponding .Rd sources. They are never committed to git, so any "View source" link pointing to them will 404 regardless of which branch it targets.

Fix

Created altdoc/man/_metadata.yml — Quarto's per-directory metadata file — with:

repo-actions: [edit, issue]

This removes the "View source" button specifically for pages rendered from altdoc/man/, while leaving it intact for vignette pages (whose .qmd files are committed to vignettes/ and resolve correctly on GitHub).

Note on robustness: altdoc/man/_metadata.yml is committed to git. During the CI build, altdoc generates .qmd files into altdoc/man/ without cleaning the directory, so _metadata.yml should be preserved when Quarto renders. If a future altdoc update starts cleaning the directory, the symptom would be a reappearing "View source" link — easy to spot and fix.

What remains broken for non-PR builds: the repo-url in quarto_website.yml still points at github.com/UCD-SERG/rpt. Man-page .qmd files don't exist there either, so if someone enabled "source" globally again, the link would still 404 on the stable/dev docs. That's a separate pre-existing issue.


· Branch

Man-page .qmd files are generated by altdoc from .Rd sources and are
never committed to git. The "View source" link therefore 404s on every
build (PR preview or otherwise). Quarto's per-directory _metadata.yml
disables only the "source" action for the man/ subtree; vignette pages
keep all three actions because their .qmd files are in git.

Fixed "View source" for man pages

  • Read relevant files and understand current state
  • Remove altdoc/man/_metadata.yml (which was disabling "View source")
  • Create altdoc/scripts/fix-man-source-urls.sh pre-render script
  • Update altdoc/quarto_website.yml to register the pre-render script
  • Save feedback to memory and create CLAUDE.md
  • Commit and push

What changed

The previous commit removed "View source" via altdoc/man/_metadata.yml. That was wrong — the button should exist, pointing at the right file.

Root cause: Man page .qmd files are generated at build time by altdoc from man/*.Rd. They're never committed to git, so Quarto's default "View source" URL (based on the .qmd path) would 404.

Fix: A Quarto pre-render script (altdoc/scripts/fix-man-source-urls.sh) now runs after altdoc generates the .qmd files but before Quarto renders them. It injects source-url metadata into each man page .qmd front matter, pointing to the committed .Rd file:

source-url: <repo-url>/blob/<branch>/man/<name>.Rd

For this PR's preview, clicking "View source" on calculate_summary will resolve to:

https://github.com/d-morrison/rpt/blob/claude/issue-136-pr-preview-links/man/calculate_summary.Rd

This uses repo-url and repo-branch already rewritten by the PR-preview yq step, so the timing is correct.

Also:

  • altdoc/man/_metadata.yml deleted (was the feature-suppressing file)
  • CLAUDE.md created with repo guidelines, including the "don't remove features" rule
  • Feedback saved to memory
    · Branch

Instead of disabling "View source" via _metadata.yml (which removed the
feature entirely), add a Quarto pre-render script that injects a correct
`source-url` into each altdoc-generated man page .qmd before Quarto
renders it, redirecting "View source" to the committed .Rd file.

- Remove altdoc/man/_metadata.yml (was suppressing the source button)
- Add altdoc/scripts/fix-man-source-urls.sh (pre-render: reads repo-url
  and repo-branch from quarto_website.yml, already mutated for PR builds,
  and writes source-url: <url>/blob/<branch>/man/<stem>.Rd into each
  generated altdoc/man/*.qmd front matter)
- Register the script under project.pre-render in quarto_website.yml
- Add CLAUDE.md with repo guidelines including "don't remove features"

Fixed "View source" for man pages

  • Read CLAUDE.md and understand repo guidelines
  • Examine current fix-man-source-urls.sh script
  • Check docs.yaml workflow and altdoc/quarto_website.yml
  • Diagnose root cause
  • Rewrite fix-man-source-urls.sh as a post-render HTML patcher
  • Update altdoc/quarto_website.yml to register it as post-render
  • Commit and push

Root cause

The previous fix injected source-url: into the generated .qmd front matter as a pre-render step. source-url is not a recognized Quarto per-page metadata key for overriding the "View source" link — Quarto silently ignored it and kept computing the source URL from the .qmd file path, which doesn't exist in the repo and 404s.

CI logs confirmed the script ran (Running script 'scripts/fix-man-source-urls.sh' in the build at 18:52 UTC on 2026-05-25) but the injection had no effect on the rendered output.

Fix (commit f5d8093)

Switched from pre-render front-matter injection to a post-render HTML patch:

  • altdoc/quarto_website.yml: pre-renderpost-render
  • altdoc/scripts/fix-man-source-urls.sh: completely rewritten — after Quarto renders docs/man/<stem>.html, replaces every href="…/man/<stem>.qmd" with href="…/man/<stem>.Rd" using a regex substitution

This approach operates on the final HTML output, so it works regardless of Quarto's internal metadata handling. The PR-preview repo-url/repo-branch rewrites in docs.yaml still run before rendering, so the link will already contain the correct repo and branch — only the extension needs fixing.

Expected result on the next preview build: "View source" on calculate_summary will resolve to https://github.com/d-morrison/rpt/blob/claude/issue-136-pr-preview-links/man/calculate_summary.Rd.
· Branch

The previous approach injected `source-url:` into .qmd front matter as a
Quarto pre-render step, but `source-url` is not a recognized per-page
metadata key in Quarto — it was silently ignored, so "View source" still
resolved to the .qmd path (which 404s).

Switch to a post-render script that directly rewrites the rendered HTML:
for each docs/man/<stem>.html, replace any href ending in
`/man/<stem>.qmd` with `/man/<stem>.Rd`.  This is independent of Quarto's
internal metadata handling and is guaranteed to work.

This PR-preview-links branch had independently added a CLAUDE.md that both
overlapped with the dedicated Claude Code config PR (#141) and described the

were folded into #141's canonical CLAUDE.md, so remove it here to keep this

Quarto's `issue` repo-action builds its URL from `repo-url`, which the
PR-preview step repoints at the PR head repo/branch — so the rendered
"Report an issue" link landed on the fork's /issues/new form. Add a
post-render step that repoints it at the base repository's main issues page
(https://github.com/<repo>/issues) on every build, so it's stable on dev,
release, and PR-preview docs.

  • Commit and push

Links are already correct in the current preview

I checked origin/gh-pages directly and the deployed HTML at pr-preview/pr-137/man/calculate_summary.html already has:

  • "Edit this page"https://github.com/d-morrison/rpt/edit/claude/issue-136-pr-preview-links/man/calculate_summary.Rd
  • "View source"https://github.com/d-morrison/rpt/blob/claude/issue-136-pr-preview-links/man/calculate_summary.Rd

The CI log for the 06:42 UTC docs build (run 26495360286) confirmed the post-render script ran successfully: fix-man-source-urls: patched 3 file(s). The links you saw broken were from the earlier 05:18 UTC preview; the merge-from-main commit triggered a new build that fixed them.

Version increment check

main was updated to 0.0.0.9019 (via PR #140) after the previous version bump, leaving this branch at parity. Bumped to 0.0.0.9020 and pushed (commit 72792f1).
· Branch

main merged PR #140 (add-reprexes-skill) and is now at 0.0.0.9019;
