Closes [DOCS-351](https://linear.app/codercom/issue/DOCS-351). > [!WARNING] > **DO NOT MERGE** until [DOCS-349](https://linear.app/codercom/issue/DOCS-349) ([coder.com#877](https://github.com/coder/coder.com/pull/877)) has shipped to production and baked for at least one Vercel cycle. > > Without DOCS-349, the relative links in this PR resolve to broken docs-route URLs (`/docs/helm/coder/values.yaml` -> 404) instead of GitHub URLs tagged with the displayed docs version. DOCS-349 fixes the rewriter to classify these as GitHub blob/tree URLs with the page's resolved ref. ## TL;DR Converts 121 absolute `https://github.com/coder/coder/(blob|tree)/main/<path>` links across 39 docs markdown files to relative paths. After this lands AND DOCS-349 deploys, every one of these links will follow the displayed docs version (mainline tag on bare URLs, explicit tag on `/@vX.Y.Z/`, `main` on `/@main/`) instead of always pointing to `main`. ## Why Today a reader on `/docs/@v2.30.0/install/docker` follows a `compose.yaml` link and arrives at `main`'s `compose.yaml`, which doesn't necessarily match what the docs page describes. Helm values, Terraform templates, and source-code references in particular drift across versions. The fix is to let the coder.com rewriter substitute the page's resolved ref into the URL; that only works on relative links. ## Example payoff (post-DOCS-349) | URL | Today (absolute, always `main`) | After (relative + rewriter) | |---|---|---| | `/docs/install/docker` | `https://github.com/coder/coder/blob/main/compose.yaml` | `https://github.com/coder/coder/blob/v2.34.1/compose.yaml` (today's mainline) | | `/docs/@v2.30.0/install/docker` | same as above | `https://github.com/coder/coder/blob/v2.30.0/compose.yaml` | | `/docs/@main/install/docker` | same as above | `https://github.com/coder/coder/blob/main/compose.yaml` | ## Scope - **121 conversions** across **39 files**. - Verb breakdown: `tree/main` (directories) and `blob/main` (files), both flipped to relative paths. - Line anchors (`#L23-L24`) and query strings preserved verbatim. - Conversion is mechanical: relative path computed from the doc file's directory to the target via `os.path.relpath`. Any path starting at the same directory or below gets a `./` prefix; otherwise `../` chains. ## Rebased on main The branch was rebased onto `main` after the DOCS-350 hotfix ([#26339](https://github.com/coder/coder/pull/26339)) merged. The hotfix repointed 3 `docs-backend-contrib-guide` refs in `backend.md` to `main`, which then needed the same `main` -> relative conversion this PR is doing for the other 121 links. The conflict was resolved by reapplying the mechanical conversion to `backend.md` after taking the hotfix's content. Net result: those 3 links land here as relative, same as everything else. New HEAD `3f501cb622`. ## Inline fix folded in: dead `nix` link - `docs/about/contributing/CONTRIBUTING.md:7` -> `../../../nix` The original absolute URL `https://github.com/coder/coder/tree/main/nix` already returned 404 today. Repointed to `flake.nix` (modern Nix entrypoint, what the prose "Nix environment" semantically refers to). Closes [DOCS-357](https://linear.app/codercom/issue/DOCS-357) here since the `check-docs` Linkspector job surfaced it during rebase; cheaper to fix inline than in a separate single-line PR. ## Out of scope (filed separately) - [DOCS-350](https://linear.app/codercom/issue/DOCS-350): 3 dead `docs-backend-contrib-guide` branch refs in `backend.md` ([#26339](https://github.com/coder/coder/pull/26339), merged). - [DOCS-352](https://linear.app/codercom/issue/DOCS-352): 10 SHA-pinned `(blob|tree)/<sha>` links pending intent review. - [DOCS-355](https://linear.app/codercom/issue/DOCS-355): code-server analog (4 absolute `(blob|tree)/main` links in `coder/code-server`). - [DOCS-356](https://linear.app/codercom/issue/DOCS-356): 2 upstream content bugs in `coder/code-server/docs/CONTRIBUTING.md` (independent of this PR). ## Not triggering `/coder-agents-review` Docs-only edit; per `AGENTS.md` the bot review is reserved for product/CI changes. ## Pre-mortem | Concern | Mitigation | |---|---| | Merging before DOCS-349 deploys regresses ~120 currently-working links into 404s on coder.com | Clear DO-NOT-MERGE banner; tracked as blocker in Linear. | | Relative path computed incorrectly (off-by-one `..`) | Verified all 114 newly-relative non-md/non-image paths resolve to existing files in the repo (only exception is the pre-existing dead `nix` link above). | | Line anchors stripped during conversion | Preserved by the substitution regex; verified `#L<n>-L<m>` cases in `airgap.md` and `speed-up-templates.md`. | | Future code reorgs change file locations | Relative links will start pointing to nothing. Same failure mode as absolute links pointing to renamed files; can be caught with a future link-checker job. | ## Validation ``` $ grep -rE 'github\.com/coder/coder/(blob|tree)/main' docs --include="*.md" | wc -l 0 $ git diff --stat origin/main | tail -1 39 files changed, 118 insertions(+), 118 deletions(-) ``` 114 newly-relative paths verified to resolve to existing repo files (Python `os.path.exists` check on each computed target). <details> <summary>Decision log + planning context</summary> **Why relative over `(blob|tree)/{{currentDocsVersion}}/...` templating**: relative paths require zero markdown-system support and zero upstream churn beyond this one PR. Templating would require a preprocessor on `coder.com` side AND a convention upstream authors have to remember; relative paths just work in a plain editor and `github.com`'s own renderer too. **Why `./` prefix on same-directory targets**: makes the conversion grep-able later (`grep -E '\((\.\./|\./)'`). **Why preserve `#L<n>-L<m>` anchors verbatim**: the anchor is meaningful to the linked file's content, not to the URL form; keeping it as-is preserves authorial intent. If the file later changes such that the line range drifts, that's a different problem the SHA-pin audit ([DOCS-352](https://linear.app/codercom/issue/DOCS-352)) will surface. </details> --- *Generated by Coder Agents on @nickvigilante's behalf.* ## Drive-by external link fix folded in `docs/about/contributing/CONTRIBUTING.md:296` cited `https://reflectoring.io/meaningful-commit-messages/` which is returning HTTP 503 (the host appears to be down site-wide right now). `check-docs` Linkspector flagged it after the rebase. Replaced with `https://cbea.ms/git-commit/` (Chris Beams' canonical "If applied, this commit will..." article, confirmed 200), which is the original source of the rule the prose recites anyway.
