Migrating TDS from Docsify to Hugo

Sat, 07 Feb 2026 12:01:10 +0800

This morning, I migrated my Tools in Data Science course page from Docsify to Hugo using Codex.

Why? Because Docsify was great for a single term. For multiple terms, archives became complex. I still could have made it work, but it felt like time to move towards a static site generator.

I don’t know how Hugo or Go work. I didn’t look at the code. I just gave Codex instructions and it did the rest.

This gives me a bit more confidence that educators can start creating their own course sites without needing coding or platforms. Soon, they might not be stuck to LMSs either - they can build their own.

Here are the prompts I used, along with Codex’s responses, leading to two commits:

Prompt 1

Generate a MIGRATION-PLAN.md for migrating this student course site from docsify to Hugo.

Currenty, this site uses docsify to render Markdown as HTML on the fly.

Create a setup.sh that generates a static version of the site under public/ using Hugo.

Use a popular, elegant, minimal Hugo theme of your choice. We want to retain the sidebar navigation, as well as the archives under 2025-01/, 2025-05/, 2025-09/, and more in the future.

Minimize the custom coding needed to achieve this.

Agent response

I’ll inspect the repository structure to map the current Docsify content layout, then I’ll create MIGRATION-PLAN.md and a setup.sh that builds a Hugo static site into public/ with minimal custom logic and preserved sidebar/archive organization.

I found the Docsify setup and the key files (index.html, root _sidebar.md, plus archive subfolders with their own _sidebar.md/README.md). Next I’ll inspect those files and then draft a migration plan plus an idempotent setup.sh that maps this structure into Hugo with minimal custom templates.

I have enough context to implement this cleanly. I’m now choosing a Hugo docs theme and validating its sidebar configuration model so setup.sh can auto-generate navigation from your existing _sidebar.md files with minimal maintenance for future archive terms.

I validated hugo-book and will use it because it gives a built-in left docs sidebar with minimal configuration. I’ll now implement setup.sh to generate a Hugo workspace from your existing markdown tree and build to public/, then add MIGRATION-PLAN.md describing the migration steps and rationale.

I’m about to add two files: setup.sh (idempotent Hugo build pipeline into public/) and MIGRATION-PLAN.md (phased migration plan, structure mapping, and rollout checks). I’ll keep the approach low-code by relying on Hugo Book’s built-in sidebar behavior and automatic archive folder discovery.

I’ve written both files and will quickly sanity-check them (including a dry run of setup.sh in this environment, which should currently fail early because hugo isn’t installed here).

I found one cleanup point: setup.sh checked for rsync even though it doesn’t use it. I’ll remove that extra dependency and then provide a concise summary of what was added.

Created both requested files:

MIGRATION-PLAN.md
setup.sh

What I implemented:

Chose hugo-book as the theme (popular, minimal, docs-style sidebar).
setup.sh now:
- Creates an isolated Hugo workspace at .hugo-build/site
- Clones hugo-book
- Generates hugo.toml
- Copies tracked markdown into Hugo content/
- Converts every README.md to _index.md (so /, /2025-01/, /2025-05/, /2025-09/ keep clean section URLs)
- Skips Docsify-only _sidebar.md
- Copies all tracked non-markdown files into Hugo static/
- Builds static output into public/

Notes:

I could not run a full build here because hugo is not installed in this environment (Error: missing required command 'hugo').
Once Hugo Extended is installed, run:

./setup.sh

Files:

setup.sh
MIGRATION-PLAN.md

Prompt 2

Use mise x hugo -- hugo and run and test it.

Agent response

I’ll run setup.sh through mise x hugo -- so Hugo is available in PATH for the script, then verify the generated public/ output and key archive routes.

The first run failed because mise couldn’t write under ~/.cache/mise in this sandbox. I’ll rerun using a temporary cache directory and then validate the generated site.

mise x hugo -- hugo is installing the standard Hugo binary (not Extended), so the script’s Extended check fails. I’ll quickly check the available mise variants and use an Extended one to complete the test run.

mise does not expose an “extended” Hugo variant here. I’ll make setup.sh tolerant of standard Hugo (warn instead of hard-fail), then run it with mise x hugo -- and verify whether the build succeeds end-to-end.

The build failed exactly at SCSS compilation, so we do need Hugo Extended for hugo-book. I’m testing mise x hugo@extended -- hugo with temporary mise data/cache dirs to keep everything inside writable paths.

Found the issue: with mise, Extended is a separate tool named hugo-extended (not a variant of hugo). I’ll run using that to complete the test build.

Build now succeeds with Hugo Extended. I’m validating the generated public/ output, including root and archive routes plus sidebar links.

Ran and tested.

Results:

mise x hugo -- hugo version

Output: hugo v0.153.3 ... (non-extended)

mise x hugo -- ./setup.sh

Fails at SCSS compile (TOCSS ... you need the extended version) because hugo-book requires Hugo Extended.

mise x hugo-extended -- hugo version

Output: hugo v0.155.2+extended ...

mise x hugo-extended -- ./setup.sh

Succeeds.
Generated site at public/
Build summary: Pages 289, Static files 103, total ~1.6s.

Validation checks passed:

public/index.html exists
public/2025-01/index.html exists
public/2025-05/index.html exists
public/2025-09/index.html exists
Sidebar contains links for archive terms and pages like marks-dashboard and system-requirements.

I also adjusted setup.sh so non-extended Hugo emits a warning instead of exiting immediately (setup.sh). The actual build still correctly fails later if the active theme needs Extended.

Prompt 3

The sidebar for the home page should only contain the contains of _sidebar.md. The sidebar for 2025-01/, 2025-05/, and 2025-09/ should only contain the contents of the respective folders’ _sidebar.md.

Convert any links to images/ to an absolute link starting with /images/.

Re-run.

Agent response

I’ll update setup.sh to generate section-specific sidebars directly from each _sidebar.md (root and archive folders), override Hugo Book’s menu partial to use those sidebars, rewrite images/ links to /images/, then rebuild and verify the output.

I’m editing setup.sh now to: 1) normalize _sidebar.md into per-section sidebar files, 2) override Hugo Book’s menu partial to render only the correct sidebar by section, and 3) rewrite markdown links from images/ or ../images/ to /images/. Then I’ll rebuild and verify.

Implemented and re-ran with your requirements.

Changes made in setup.sh:

Sidebar behavior:
- Added per-section sidebar generation from source _sidebar.md files:
  - root: _sidebar.md
  - 2025-01/: 2025-01/_sidebar.md
  - 2025-05/: 2025-05/_sidebar.md
  - 2025-09/: 2025-09/_sidebar.md
- Added a Hugo Book partial override at .hugo-build/site/layouts/_partials/docs/menu-filetree.html during build so:
  - home and non-archive pages use only root _sidebar.md
  - pages under /2025-01/, /2025-05/, /2025-09/ use only their own folder sidebar
Link normalization in sidebars:
- Converts .md links to Hugo-style paths (e.g. /foo/)
- Normalizes sidebar-local links like http-requests to /http-requests/
- Removes docsify inline <style> lines from sidebars
Image link rewrite in content:
- Rewrites markdown links from (images/... and (../images/... to (/images/... while copying content into Hugo.

Re-run/test:

mise x hugo -- ./setup.sh still fails because hugo-book needs Extended Hugo (SCSS pipeline).
Successful build command:
- XDG_CACHE_HOME=/tmp MISE_CACHE_DIR=/tmp/mise-cache MISE_DATA_DIR=/tmp/mise-data mise x hugo-extended -- ./setup.sh
Build passed and generated public/ successfully.

Verified output:

Home sidebar only has root _sidebar.md entries (Jan 2026..., Marks Dashboard) in public/index.html.
public/2025-01/index.html sidebar matches 2025-01/_sidebar.md only.
public/2025-05/index.html sidebar matches 2025-05/_sidebar.md only.
public/2025-09/index.html sidebar matches 2025-09/_sidebar.md only.
Image references are rewritten, e.g. src=https://www.s-anand.net/blog/images/portal_notifications.webp in rendered pages.

Prompt 4

The Next and Previous buttons at the bottom should follow the _sidebar.md navigation order in each folder. Add a dark/light mode toggle. Add a GitHub action to deploy this to GitHub pages

Agent response

I’ll extend the build so Hugo uses _sidebar.md order for page-to-page navigation, add an explicit dark/light toggle in the generated site, and create a GitHub Actions workflow that builds with Hugo Extended and deploys public/ to GitHub Pages.

I identified how Hugo Book computes prev/next today; I’m now overriding that partial to read an explicit per-sidebar navigation sequence so buttons follow _sidebar.md order exactly. I’ll also add a small injected toggle that switches BookTheme between light and dark at runtime.

I’m implementing three concrete updates now: generate sidebar-order data from _sidebar.md, override Hugo’s prev-next partial to use that order, and inject a real dark/light toggle using custom SCSS + a small script. After that I’ll add the Pages deployment workflow and run a full rebuild.

I’ve added the workflow and finished the setup.sh changes. Next I’m running a full build with Hugo Extended and validating: 1) prev/next order matches sidebar sequences, and 2) the theme toggle appears and works via injected script/CSS.

The rebuild now passes, and spot checks confirm: footer navigation follows sidebar order (e.g., marks-dashboard -> development-tools -> vscode for the Sep 2025 sequence), plus the dark/light toggle is present and persisted via local storage. I’ll do one final status check and summarize exact file changes.

Implemented all three requests and re-ran successfully.

What changed:

setup.sh
- Added sidebar-order extraction from _sidebar.md into data/sidebar-nav.yaml.
- Added custom prev-next partial override so footer navigation follows _sidebar.md order.
- Kept section-specific sidebar rendering:
  - root pages use root _sidebar.md
  - 2025-01/, 2025-05/, 2025-09/ use their own _sidebar.md
- Added dark/light mode toggle:
  - injects toggle button in sidebar
  - persists preference in localStorage (tds-theme)
  - applies theme via custom SCSS overrides using Hugo Book mixins.
- Kept image link rewrite to absolute /images/....
.github/workflows/deploy-pages.yml
- Added GitHub Pages deployment workflow:
  - triggers on push to main and manual dispatch
  - installs Hugo Extended (peaceiris/actions-hugo@v3)
  - runs ./setup.sh
  - uploads public/
  - deploys via actions/deploy-pages@v4

Run/test performed:

Command used:
- XDG_CACHE_HOME=/tmp MISE_CACHE_DIR=/tmp/mise-cache MISE_DATA_DIR=/tmp/mise-data mise x hugo-extended -- ./setup.sh
Build passed.
Verified:
- Next/Previous follows sidebar order (example: system-requirements -> marks-dashboard -> development-tools -> vscode in Sep sequence).
- Dark/light toggle is present and persists.
- Site generated under public/.

Files:

setup.sh
.github/workflows/deploy-pages.yml

If you want, I can also add a short “Deploy” section to README.md with the exact GitHub Pages settings (Pages source = GitHub Actions).

Prompt 5

Add an appropriate Unicode “icon” for the Dark/Light Mode toggle button .gitignore public/ and any other files you create that should not be committed (if any). Move MIGRATION-PLAN.md to .hugo-build Commit

Agent response

I’ll update the toggle label to include a Unicode icon, update .gitignore for generated artifacts (public/, .hugo-build/), move MIGRATION-PLAN.md into .hugo-build/, then commit only the migration-related files.

I’m applying the requested edits now: iconized toggle text plus ignore rules, then moving MIGRATION-PLAN.md under .hugo-build/. After that I’ll stage only the intended files and commit.

I’ve moved the migration plan and updated the scripts. I’ll run one quick rebuild to ensure the iconized toggle is reflected in output, then commit the exact files (setup.sh, workflow, .gitignore).

I’ve committed the requested changes. I’m doing a quick post-commit check to confirm .gitignore includes generated paths and that MIGRATION-PLAN.md now lives under .hugo-build/.

Done.

Committed as:

1dd73c6 Add Hugo sidebar-ordered nav, theme toggle icon, and Pages deploy workflow

Included in commit:

.github/workflows/deploy-pages.yml
.gitignore
setup.sh

Also completed:

Added Unicode icon treatment for theme toggle (◐, ☀, ☾) in generated site via setup.sh.
Ignored generated artifacts:
- public/
- .hugo-build/
Moved MIGRATION-PLAN.md to:
- .hugo-build/MIGRATION-PLAN.md

Note:

I did not include unrelated working tree changes (e.g. existing README.md modification and other untracked project files) in the commit.

Prompt 6

Don’t implement it, but just tell me: what’s the most elegant, minimal way (directory structure wise) to commit the files setup.sh creates, like hugo.toml, menu-filetree.html, head.html, etc? That way, setup.sh becomes smaller, cleaner, easier to read, and the other files are easier to edit.

Agent response

Most elegant minimal pattern: commit a tiny Hugo scaffold once, and let setup.sh only do content sync + build.

Use this structure in-repo:

hugo/
  hugo.toml
  layouts/
    _partials/
      docs/
        menu-filetree.html
        prev-next.html
        inject/
          head.html
          menu-after.html
  assets/
    _custom.scss
  data/
    sidebar-nav.yaml        # generated by setup.sh (or committed if static)
  sidebars/
    root.md                 # generated by setup.sh (or committed if static)
    2025-01.md
    2025-05.md
    2025-09.md

Then setup.sh just:

Creates .hugo-build/site
Copies hugo/* into it
Clones/uses theme
Generates only dynamic files (data/sidebar-nav.yaml, maybe sidebars/*.md)
Copies content/static
Runs Hugo

If you want even cleaner: keep theme as a Hugo module in hugo.toml and remove theme clone logic too.

Prompt 7

What would the file and directory structure look like if we went the “even cleaner” route?

Agent response

Key point: with Hugo Modules, there is no committed themes/ directory and no git clone theme step in setup.sh.

Prompt 8

I want the sidebars to stay where they are. Given this, what will be the only files that get committed?

Agent response

If sidebars remain in-place (_sidebar.md, 2025-01/_sidebar.md, etc.), then only commit the Hugo scaffold and automation files:

setup.sh
.github/workflows/deploy-pages.yml
hugo/hugo.toml
hugo/assets/_custom.scss
hugo/layouts/_partials/docs/menu-filetree.html
hugo/layouts/_partials/docs/prev-next.html
hugo/layouts/_partials/docs/inject/head.html
hugo/layouts/_partials/docs/inject/menu-after.html
.gitignore updates (for public/, .hugo-build/)

Everything else (public/, .hugo-build/, generated nav/sidebar data) stays uncommitted/generated at build time.

Prompt 9

OK, implement that, run and test.

Agent response

I’m going to refactor to the committed Hugo scaffold layout now: move static template/config/style content into hugo/, shrink setup.sh to orchestration only, then run a full build and verify sidebar behavior, prev/next order, and theme toggle.

I confirmed go is not installed locally, so for the Hugo-module route I’ll also wire go into the workflow and test locally with mise x go hugo-extended -- ./setup.sh. I’m now creating committed scaffold files under hugo/ and rewriting setup.sh to just copy scaffold + generate dynamic sidebar data + build.

I’ve finished the refactor to committed scaffold files under hugo/. I’m now running a full build using mise x go hugo-extended -- ./setup.sh and then validating sidebar scoping, prev/next order, and toggle presence in generated HTML.

The first module-based run failed because Hugo Modules needs initialization in the temporary site (go.mod). I’ll add hugo mod init (and module fetch) inside setup.sh, then rerun the build and checks.

Implemented.

What changed:

Refactored to committed Hugo scaffold files under hugo/:
- hugo/hugo.toml (Hugo Module import for github.com/alex-shpak/hugo-book)
- hugo/assets/_custom.scss
- hugo/layouts/_partials/docs/menu-filetree.html
- hugo/layouts/_partials/docs/prev-next.html
- hugo/layouts/_partials/docs/inject/head.html
- hugo/layouts/_partials/docs/inject/menu-after.html
Simplified setup.sh:
- Copies hugo/ scaffold into .hugo-build/site
- Initializes/fetches Hugo modules (hugo mod init, hugo mod get -u)
- Generates normalized sidebars and data/sidebar-nav.yaml from existing _sidebar.md files in-place
- Copies content/static and rewrites images/ links to /images/
- Builds into public/
Updated GitHub Pages workflow:
- .github/workflows/deploy-pages.yml now sets up Go (actions/setup-go@v5) before Hugo Extended.

Run/test:

Executed:
- XDG_CACHE_HOME=/tmp MISE_CACHE_DIR=/tmp/mise-cache MISE_DATA_DIR=/tmp/mise-data GOMODCACHE=/tmp/go-mod-cache GOPATH=/tmp/go-path mise x go hugo-extended -- ./setup.sh
Result:
- Build succeeded (Pages: 289) and generated public/.

Validated behavior after refactor:

Sidebar scoping still correct (home/root sidebar only root entries; 2025-09 uses only its sidebar).
Footer Previous/Next still follows _sidebar.md order.
Dark/light toggle still present with Unicode icons (◐, ☀, ☾) and persisted theme state.

I have not made a new commit in this step.

Prompt 10

Document what each section in setup.sh does and why. A future reader should not be confused. Also document any other sections you created in this session. Then commit.

Agent response

I’ll add clear section-level comments in setup.sh and concise purpose comments at the top of each newly added Hugo override/workflow file so a future maintainer can understand what exists and why, then I’ll commit those documentation-only changes.

I’m now adding maintainership-focused comments to every new/modified scaffold file (setup.sh, Hugo partials/config, SCSS, workflow), then I’ll run a quick build sanity check and commit.

I’ve added section-level documentation across setup.sh and all related scaffold/workflow files. I’ll run one build sanity check, then commit these documentation updates.

Done. I added documentation comments for maintainability across all migration files and committed.

Committed:

- Added clear section headers and “why” comments for:
  - path setup
  - dependency checks
  - clean build lifecycle
  - scaffold copy
  - Hugo module init/fetch
  - sidebar normalization

Validation run:

Rebuilt successfully with:
- mise x go hugo-extended -- ./setup.sh
Build output still succeeds (public/ generated).

Prompt 11

I made a few changes:

I also used dprint to format Markdown files via npm run lint.
In setup.sh I replaced rg with grep since it’s not available in the CI pipeline.
I squash-merged the changes so far.

Now, when I visit /2025-09/ (or any other archive page) it shows me the sidebar correctly. But when I click on the next link, e.g. /system-requirements/ the sidebar becomes that of the root /_sidebar.md. I want to retain the sidebar for each course. So I guess the best way is to copy the content into 2025-09/ and 2025-05/ and 2025-01/ folders respectively. In the future, I will have other courses starting with 2026-_ or 2027-_ etc. It’s safe to say that any folder with a 20YY-MM/ format is a course folder and should have its own sidebar.

Modify minimally and elegantly to handle this required. Run and test. Commit as you go.

Agent response

I understand: for any 20YY-MM/ course, navigation should stay inside that course context (/2025-09/...) so sidebar never falls back to root while moving through next/previous links. I’ll inspect the current setup.sh and generated scaffold, then patch minimally with dynamic course-folder handling and test end-to-end.

I’ve identified a minimal fix: detect all 20YY-MM course folders dynamically, generate course-prefixed sidebar links, and clone shared top-level markdown pages into each course path so navigation stays in-course. I’m applying that now to setup.sh plus the two Hugo partials.

I’ve patched dynamic course detection and course-prefixed navigation. Next I’m running a full build and verifying that /2025-09/ -> next -> /2025-09/system-requirements/ keeps the 2025-09 sidebar (and same for other courses).

Build and behavior checks passed for 2025-09, 2025-05, and 2025-01. I’m committing the minimal fix now (only setup.sh and the two sidebar/nav partials).

Implemented with minimal changes and committed.

Commit:

c54ec05 Keep course sidebar context across next/prev via dynamic course routes

What changed:

setup.sh
- Detects course folders dynamically using 20YY-MM pattern.
- Generates course sidebars for all detected folders (not hardcoded to 2025-*).
- Normalizes course sidebar links to course-scoped URLs (e.g. /2025-09/system-requirements/).
- Generates data/sidebar-nav.yaml dynamically for root + all courses.
- Duplicates shared top-level markdown pages into each course path so course-scoped links resolve.
hugo/layouts/_partials/docs/menu-filetree.html
- Sidebar selection is now dynamic by URL prefix ^/20YY-MM/.
- No hardcoded course list.
hugo/layouts/_partials/docs/prev-next.html
- Prev/Next now uses the dynamic course key from path prefix.
- Keeps navigation inside the current course context.

Run and test:

Built with:
- mise x go hugo-extended -- ./setup.sh
Verified outputs exist:
- public/2025-09/system-requirements/index.html
- public/2025-05/development-tools/index.html
- public/2025-01/development-tools/index.html
Verified behavior:
- /2025-09/ next link points to /2025-09/system-requirements/
- /2025-09/system-requirements/ shows 2025-09 sidebar (not root)
- Same in-course next/prev behavior confirmed for 2025-05 and 2025-01.

Prompt 12

Ensure that:

The current page is highlighted on the sidebar
The next / previous pages show the titles of the pages they link to, not just the title-cased filenames

Again, think about the most minimal, elegant, way to do this.

Agent response

I’ll make two small targeted changes: enrich generated sidebar-nav data with label text from _sidebar.md for accurate next/previous titles, and add a lightweight sidebar-active-link highlighter script so the current page is visibly selected. Then I’ll rebuild and verify.

I’m now updating the nav data format to store both path and human-readable title from _sidebar.md, then switching prev-next to use those titles. I’ll also add a tiny sidebar script for active-link highlighting with minimal CSS.

I’ve applied the minimal patches. I’ll now rebuild and verify two things in generated output: active sidebar class appears on the current page link, and next/previous labels use _sidebar.md titles (e.g. “System Requirements”, “Marks Dashboard”).

Build failed due a Hugo template type issue in prev-next (empty dict fields). I’m applying a safe guard in the template to only read path/title when present, then rerunning the build.

The rebuild now passes; next/previous titles are sourced from sidebar labels. I’ll commit these minimal updates (nav-title mapping + active-link highlighter) and summarize the exact behavior change.

Implemented minimally and committed.

Commit:

44ea7b6 Use sidebar labels for prev/next and highlight active sidebar link

What changed:

setup.sh
- Sidebar nav data now stores both:
  - path
  - title (taken from _sidebar.md link text)
- This preserves human-written titles for navigation labels.
hugo/layouts/_partials/docs/prev-next.html
- Prev/next now reads from { path, title } entries.
- Footer labels use sidebar titles (e.g. System Requirements, Marks Dashboard, 1. Development Tools) instead of derived filename titles.
- Falls back to Hugo page title only if sidebar title is missing.
hugo/layouts/_partials/docs/inject/menu-after.html
- Added a lightweight runtime highlighter:
  - compares current pathname with sidebar link hrefs
  - adds active class and aria-current="page" to the current sidebar link
hugo/assets/_custom.scss
- Added explicit .book-menu-content a.active styling so current page is visibly highlighted.

Run/test:

Rebuilt successfully with:
- mise x go hugo-extended -- ./setup.sh
Verified in generated HTML:
- Prev/next labels now use sidebar titles:
  - /2025-09/system-requirements/ prev = Sep 2025: Tools in Data Science, next = Marks Dashboard
  - /2025-09/marks-dashboard/ prev = System Requirements, next = 1. Development Tools
- Active-link script and style are present in output and will apply on page load.

Prompt 13

Do we really need go and hugo extended? Check if it can run without.

Agent response

I’ll run four quick matrix checks to isolate requirements: hugo only, go+hugo, hugo-extended only, and go+hugo-extended, then report exactly which dependency is truly required and why.

I’m waiting on the final success/failure output for the go + hugo-extended run to complete the matrix conclusively.

Short answer: with the current architecture, yes, both are required.

I ran checks:

hugo only

Command: mise x hugo -- ./setup.sh
Result: fails immediately with Error: missing required command 'go'

hugo-extended only

Command: mise x hugo-extended -- ./setup.sh
Result: same failure: missing required command 'go'

go + hugo (non-extended)

Command: mise x go hugo -- ./setup.sh
Result: fails during build with SCSS error (TOCSS ... need the extended version)

So:

go is required because setup.sh uses Hugo Modules (hugo mod init/get) to fetch hugo-book.
hugo-extended is required because hugo-book compiles SCSS (book.scss).

If you want to drop one:

Drop go: stop using Hugo Modules (vendor/submodule theme in repo).
Drop hugo-extended: use a theme without SCSS compilation (or precompiled CSS-only setup).

Prompt 14

How do I install hugo-extended?

Agent response

Use one of these.

mise (recommended in this repo):

mise use -g hugo-extended@latest
hugo version

Agent response

This error is from the prev-next template assuming every nav item is an object with path/title. I’ll patch it to gracefully handle both shapes ("string" and {path,title}), so stale/generated data won’t break builds, then I’ll test and give you the exact recovery commands.

hugo-extended is installed correctly. This error is a template/data mismatch, not an install issue.

Your prev-next.html expects nav items like:

- path: "/2025-09/system-requirements/"
  title: "System Requirements"

But your current setup.sh is still generating plain strings:

- "/2025-09/system-requirements/"

So {{$item.path}} fails.

Fix

Make sure you’re on the latest commit where this was fixed (44ea7b6), or update setup.sh so write_sidebar_nav_yaml() writes both path and title.
Clean generated artifacts:

rm -rf .hugo-build public

Run from repo root (the directory containing .git):

pwd
ls -la .git
mise x go hugo-extended -- ./setup.sh

If you want, I can give you a minimal patch for just write_sidebar_nav_yaml() and prev-next.html to make it robust even if old string-format data appears.

I’m in the right directory, with the .git. Here’s what I get:

Agent response

You’re right, thanks for sharing the exact trace. I’ll make prev-next.html backward-compatible so it works whether nav entries are strings or {path,title} objects, then you can rebuild without depending on one exact setup.sh data format.

I’ve patched the template to accept both data shapes. I’ll quickly run the build once to confirm the error is gone.

Good catch: Hugo evaluates index eagerly, so I rewrote it with explicit if branches to avoid indexing strings. I’ll rerun the build now.

There’s one more edge case: when no prev/next exists, the placeholder map produced a non-string path. I’m patching that guard now (isset checks before reading path/title) so empty edges don’t break rendering.

I’ve reproduced your exact error and fixed it by making prev-next.html robust to both nav data formats. I’m committing this as a small compatibility fix so you can cherry-pick or pull it cleanly.

You’re hitting a real compatibility bug, not an install issue.

Root cause:

Your prev-next template is reading item.path.
Your generated nav data in some runs is still a plain string list.
Hugo errors with: can't evaluate field path in type interface {}.

I fixed this by making prev-next.html support both:

string entries ("/2025-09/system-requirements/")
object entries ({ path, title })

Commit:

b856e7c Make prev/next template compatible with string and object nav entries

I also verified the build succeeds after this fix with:

mise x go hugo-extended -- ./setup.sh

What you should do:

Pull latest hugo branch (or cherry-pick b856e7c).
Re-run:

rm -rf .hugo-build public
mise x go hugo-extended -- ./setup.sh

If you want, I can also give you a one-command patch snippet to apply manually without pulling.

Migrating my blog from WordPress to Hugo

Fri, 02 Jan 2026 12:30:00 +0800

In 2009, I migrated from a self-made Perl static site generator to WordPress because it was slow, WordPress was dynamic and rapidly growing in features, and I wanted to write rather than code. (Also, I had plenty of time in 2009 for such things!)

Over the years, problems crept in. Hosting costs ($200/year) for a slow server. No local writing - Windows Live Writer was dead. I wasn’t using most WordPress features. So it was time to migrate back to a static site generator. (Also, I now have plenty of time for such things!)

I tried in 2024. But the complexity of the migration was higher than my laziness. (I tried with LLMs. Didn’t work.)

Finally, in Dec 2025, coding agents were good enough to get this done. Codex and Claude Code both doubled their limits for the holidays, and I had no meetings. So, over two days, I joyfully migrated to a static site.

Content is written in Markdown via VS Code and pushed to https://github.com/sanand0/blog/
A GitHub Action deploy.yaml publishes to GitHub Pages
It uses a hugo.toml configuration with supporting scripts.

Here’re the useful practices I distilled from my prompts.

Create a `PLAN.md` before complex tasks

Create a plan in PLAN.md to convert my blog into Markdown-based content I can commit on GitHub and is published via a static site generator retaining the same URLs.

My website https://s-anand.net/ hosts a WordPress blog at https://s-anand.net/blog/ and I have exported the content as an XML file using the WordPress export tool into sanand.WordPress.2025-12-28.xml. Read it to understand.

Each post and page must become a Markdown file with front-matter containing all metadata (title, date, tags, categories, slug, author, etc). The Markdown must be stored as

- ./metadata.yml (for site-wide metadata)
- ./posts/yyyy/yyyy-mm-dd-slug.md
- ./pages/slug.md
- ...

You can browse the site https://s-anand.net/blog/ to see the site structure and all the types of pages that are generated.
You can also "ssh sanand" to access the server and `cd www/blog/` to see the WordPress configuration.

Note that some posts / pages have complex content: tables, code, embedded media, shortcodes, JavaScript, etc. Identify all such cases and how to handle them. There may still be edge cases that you don't know how to handle; list them out. This is a major part of the plan - ensuring that you cover all types of content -- either with a plan to handle it easily and elegantly, or explicitly identifying ALL edge cases and listing them.

Include how to handle images and other media. The WordPress export XML file may not contain the actual media files; identify how to get them. Suggest how to store them - I can store them in the Git repo, or in GitHub releases (needs to be fetched during CI process), or in R2 (direct access like a CDN). I would also like to compress media (e.g. to WebP) for better performance.

I plan to use either of these hosting options. Let me know what you prefer:

- GitHub CI to deploy to GitHub Pages (preferred: it's free, easy, and reliable).
- OR, convert locally to static HTML and upload to R2 / CloudFlare pages (priced, more effort, but reliable).

Suggest a static site generator (SSG) to use. I prefer something FAST and simple. I prefer single-binary SSGs or installation-free SSGs (e.g. via npx, uvx) if possible.

Consider any other requirements I may have missed, e.g. plugin features, SEO, redirects, analytics, comments, search, RSS feeds, sitemaps, etc. Going through the site or the WordPress configuration may help identify these. Suggest how to handle them.

It analyzed my blog: blocks and shortcodes used, plugins, URL structure, etc. and came up with a pretty good plan. Here are some notes:

Record unresolved edge cases for manual review. (Wise!)
Prefer raw HTML inside Markdown when conversion would lose fidelity. (Interesting! Also has detailed rules for tables, code, figures, iframes, forms, …)
Frontmatter: Required: title, date, lastmod, slug, author, categories, tags, status, draft, canonical, summary/excerpt, comment_status, ping_status. (Um… too much?)
Use Hugo (single binary, fast, built-in RSS/sitemap/taxonomies, supports raw HTML and shortcodes) and GitHub Pages via GitHub Actions.

There’s no way I would have thought of all of these!

Analyze data while planning

Even while it was planning, another thing struck me. I won’t use GitHub to serve assets. It bloats the repo. Plus, there’s an opportunity to compress better with WebP. So I asked it to analyze my media.

I've rsynced `sanand:www/blog/wp-content/uploads/` to `./uploads/` locally.

Which uploads are unused in my blog posts / pages. Tell me the number, total size, and save them all in unused-uploads.tsv with columns size, filename.

If I convert all used images over 10KB to WebP, how much space will I save? (An estimate is fine; I don't need exact numbers.)

It parsed the WordPress export against my local uploads/, listed unused uploads (1.7K files of 87MB), and found 515 used files of 34MB. It estimated ~11MB savings from WebP conversion of used images >10KB.

Edit `PLAN.md` using the agent, not manually

Editing manually is prone to mistakes, e.g. introducing contradictions.

I am fine with Hugo + GitHub Pages.

/blog must remain the subpath - the URL structure must NOT be disturbed. Prefer publishing into a /blog/ folder.

Import old comments (prefer YAML over JSON for easy reading). The new static site will not have dynamic comments; I may switch to Giscus or Utterances later.

As for media, let's convert and save WebP versions instead of the originals and commit them directly to the Git repo under uploads/. Only used media should be included.

Revise PLAN.md accordingly. Let me know what other information you need, if any.

Useful lesson: Let me know what other information you need, if any. Life is full of unknown unknowns!

It did ask if I was OK changing URLs from .jpg|.png to .webp, which I confirmed in the next prompt.

Implement small steps, run and commit as you go

I know from experience that a single-shot implementation of this size would be too complex today. So I asked for image conversion first.

Now, implement the upload handling. Delete unused uploads (I have backups on the server). Compress JPEGs with 50% quality and PNGs losslessly with 256 colors. Let me know the revised size of assets.

I am OK with image URLs breaking.

Implement this by writing a script (bash, Python, Node JS - anything is fine, whatever is easiest) that will create an `assets/` folder with the converted images from the `uploads/` folder. I will want to re-run this later with some tweaks.

Commit as you go.

Having the agent run the script is the most powerful idea in here. If it makes a mistake, it can figure it out and fix itself.

Commit as you go is useful. I can undo changes later. I also efficiently get a sense of the progress and thinking.

It took a long time (on GPT 5.2 Codex - Extra High Thinking), wrote a scripts/prepare_assets.py, switched from ImageMagick to Pillow for better control (strange!), trouble-shooted PNG transparency bugs, ran it, noted that 41 files in my blog that were missing, and committed everything.

Run post-mortems mid-way

Strangely the JPEG files weren’t converted. So I asked:

Why does the assets/ folder still have some .jpg files, e.g. temperature.jpg? I assumed they'd all be converted to webp.

It said:

Because the script follows your latest instruction: it compresses JPEGs and PNGs in-place and keeps their original formats.

OOPS! My mistake. Anyway, I also needed it to convert MP3 to Opus. So…

Ask for actionable exception reports

Let’s have it do all the conversions.

Convert all JPEG files to WebP, too, with 50% quality. Use cwebp to convert - it is faster and has better quality.

Let's also compress audio files to OPUS with ffmpeg using `-c:a libopus -b:a 12k -ac 1 -application voip -vbr on -compression_level 10`. Modify the script accordingly.

Also modify the script to list missing local uploads/ mentioning the URL on https://s-anand.net/blog/... post or page that references each. Each line should list the missing filename and URL, tab-separated.

But note the last line. It had already identified that some uploads were missing. To action that, I would need a post -> file mapping, which I asked for.

Delegate verification to the agent

In the exception report, there was an amazoncooliri file missing. I couldn’t find it in the blog XML. So I asked:

Double-check the files mentioned in the missing-uploads.tsv. Do these files really exist in the XML? For example, it mentions "amazoncooliri". But there is no such word in the XML, I think, and uploads/amazoncooliris.jpg (which is probably what it refers to) exists. There may be similar mistakes. Make sure nothing required is missing either.

At first, I checked the code to see why amazoncooliris became amazoncooliri. But months of practicing ~~laziness~~ delegation took over and I had it debug itself.

Turned out it wrote \\s instead of \s which fixed it.

Accept that you will make mistakes

Why are there PNG images in assets? I assumed there wouldn't be any and all would be WebP files...

It replied:

Because the script only converts JPEG → WebP. For PNGs, it follows your instruction to “compress PNGs losslessly with 256 colors,” so they stay PNG.

OOPS AGAIN! I forgot to ask it to convert PNGs.

Convert all PNGs to WebP using cwebp maximal effort with 256 color palette, just like the jpegs. Update, re-run, commit.

Verification reports speed up reviews

Now for the big one: converting the blog posts.

Now implement the plan in PLAN.md to convert the WordPress XML export to Markdown files with front-matter. Write a Python script with inline dependencies that `uv run` can execute. Run it and generate all the Markdown files. Verify that everything looks good - especially edge cases.

Make a list of edge cases you could handle that I should verify.
Make a list of any edge cases you couldn't handle.
Share these as links to https://s-anand.net/blog/.... as well as the local relative paths.

Apart from converting the posts, it generated:

reports/edge-cases-unhandled.tsv – an exception report
reports/edge-cases-handled.tsv – a verification report

The verification report was handy. I could see the edge cases (e.g. upload URLs rewritten, iframes/tables/objects/scripts that were retained, WordPress comment blocks removed) and spot check quickly.

Without this, I would have spent a lot more time reviewing. This gave me confidence that it had handled edge cases well.

Generate easy-to-review to review content

I find it productive to have the agent generate content that is easy to review. At this point, I had a bunch of Markdown files that were very easy for me to scan. So I created an extensive list of changes:

Drop redundant or unchanging frontmatter. For example:

- Retain title, date, lastmod, slug, categories
- author: sanand is always the same. Drop
- draft: false and status: publish are redundant. Drop both
- url: is deriable from the slug. Drop. Same for wp_link
- If tags, excerpt, aliases, etc. are missing, drop them
- Drop meta: entirely
- Drop menu_order, ping_status, comment_status
- Drop wip_guid in favor of wp_id (retain wip_id)
- If I missed any other frontmatter, use the same principles.

Insert the featured image as the first element in the post, instead of the featured_image frontmatter.

Rewrite all the upload links (http://www.s-anand.net/blog/wp-content/uploads/xxx) to relative links to uploads/ (e.g. ../../uploads/xxx).

Rerun. Commit as you go.

Finally, write a script to detect all links to s-anand.net/ that are not covered by this approach. For example, I have a bunch of direct assets like https://files.s-anand.net/blog/a/mystic-light.mp3 or other non-WordPress pages on my website. Create a TSV report with the link and the source.

PS: I keep editing prompt.md with my prompts. Keep ignoring it.

The last line was because I was also saving my prompts and it kept getting confused why a file it didn’t create kept changing 🙂.

Give it all your tools

I had it install Hugo and run it. (I could have set it up myself, but why bother?)

I allowed it to ssh to my server to check logs if needed.

In both cases, these are tools I would need to build and test. It makes sense to let the agent use them directly.

Corrections:

- The relative URLs should be ../../assets/ not ../../uploads/ (my mistake)
- No action required on the file URLs and swf links. I'll handle those.

Now, use Hugo (install via `mise use -g hugo`) and generate a static site from the Markdown files.

Ensure that ALL the URLs from https://s-anand.net/blog/... are retained exactly, including URLs posts, pages, categories, tags, author pages, year (or other time period), etc. You can `ssh sanand` and scan logs if that'll help.

This will be deployed via GitHub pages. Create the GitHub action workflow to build and deploy the site on every push to main.

Commit as you go.

Note that I had made a mistake mentioning uploads/ instead of assets/. This keeps happening.

I don’t know any Hugo, so this was a bold step. But the output would be easy to review (it’s a static site), so more reviewability = more confidence.

After a long time, it generated the static site. It managed to self-correct a bunch of stuff. For example:

I removed --minify because inline scripts with <br /> in posts/2011/2011-05-19-eating-more-for-less.md break JS minification; HTML builds cleanly without minify.

Prefer UI reviews over code reviews for ease

In fact, if required, have it build a throw-away tool to help you review.

In my case, the output was functional but ugly. So ugly that I couldn’t review it properly. I suggested a few obvious fixes (like broken links) but the main ask was to pick a theme and make it look like my website.

FYI: I removed mise.toml. Running `mise x hugo -- hugo` should still work, but feel free to reinstall.

Ensure that ALL LINKS are relative. For example, public/blog/index.html links to https://s-anand.net/blog/tamil-ai/ but I'd like to link to tamil-ai/ instead.

Pick and implement a nice, popular, lightweight theme that's suitable for blogs.

Include these features. Where possible, use modern, well-supported & popular plugins or themes rather than custom code.

- Below the title, have a single line showing the date created (date updated shown only if different from date created), categories with links to category pages, tags with links to tag pages (if any) are present.
- Code blocks should be syntax-highlighted.
- At the bottom, include a link to the next and the previous posts (with title).
- Add a footer to all pages that lists
  - All categories with links & post count
  - All year archives with links and post count
  - All pages with links

Run and test.

You can resume if it hangs. Don’t worry about context

This took forever and I think Codex crashed or hung or something. So I killed it, resumed, and asked:

It's been a while... maybe you were stuck? Resume and complete.

It managed to resume. I’m not sure if there was some context loss or confusion, but I’m learning to worry less.

Allow it design flexibility

Internal links were still broken. I didn’t know why, nor enough to fix them. So, rather than make a design decision (e.g. always use full / absolute / relative URLs), I let it decide.

There are several problems due to wrong relative paths. If it will be easier, feel free to switch back to absolute paths for /blog/ to fix them.

- Featured image URLs seem wrong. blog/ai-can-be-held-to-account/ links to "/blog/../assets/pig-court.webp" instead of just "../assets/pig-court.webp"
- When I visit /blog/2003/ the CSS is fine but it breaks in /blog/2003/page/2/ -- and the relative links from that page also break.
- The links from the footers in /blog/2003/ point to /2016/ instead of /blog/2016/ for example

Swap "Next" and "Prev". "Prev" indicates older posts.

Syntax highlighting of code blocks doesn't seem to be working. In blog/openai-tts-cost/ I see a single block like this.

```
<code lang="bash" class="language-bash">curl "https://api.openai.com/v1/organization/usage/audio_speeches?start_time=$(date -d '1 day ago' +%s)&amp;project_ids=$PROJECT_ID&amp;group_by=model" \
  -H "Authorization: Bearer $OPENAI_ADMIN_KEY" \
  -H "Content-Type: application/json"</code>
```

It decided to use absolute paths.

Generate documentation

Apart from adding a few more features / fixes, I had it generate a README.md documenting what I would need to run this in the future.

Add featured images as thumbnails to post listings (e.g. blog home, category pages, tag pages, archive pages). Ensure that there is a placeholder (an elegant blank image) if there is no featured image.

Left-align the footer links.

Now, clean-up and add a README.md that explains the structure of the repo, how to build and deploy, etc.

I also had it fix another design error I made. The placeholders I asked for didn’t look good.

Skip featured images in post listings, post pages, etc. if they don't exist. No need for a placeholder.

Ask for effort estimates

At this point, things were fine. But I was curious if we could refactor a bit.

I’m concerned if it might mess it up, though. Effort is a good proxy for errors. So I asked it:

How easy are these changes? Just tell me, don't implement them.

- Set it up so that the content/ directory is auto-generated from posts/ without needing to be committed.
- Drop the slug: frontmatter and instead, derive it from the filename.
- Embed the comments in the posts as Markdown, clearly distinguished from the content, rather than keep them in comments/

It’s response:

Auto-generate content/ from posts/ is moderate effort…
Dropping slug frontmatter is easy if you accept Hugo’s filename‑based slug rules…
Embedding comments into each post is moderate effort…

Probe for confidence

I asked:

What's Hugo's filename-based slug rules?

I didn’t read the output. My aim was not to learn. It was more to glance at it, see if (based on my considerable experience in this area) if it looked reasonable. In short, I was probing for confidence – its and mine.

Continue the session for the long tail

Normally, I would have created a new session to implement changes and fixes.

But the session was auto-compacting quite well. So rather than lose context, I had it create a build steps and run several minor fixes over the next few days. I didn’t need to specify the context again and again.

Under the staircase of Bandra station

Fri, 16 Aug 2002 12:00:00 +0000

Under the staircase of Bandra station lies a two-storeyed apartment. Dupleix layout, single room. East-facing, with elevated entrance.

It’s 8:00am. The man on the ladder is a boot polish-walla. He’s picking up his box, getting ready for work, while his colleague watches. Their families is still asleep in the single room. And in the room, along with them, is a rather cramped storage space.

I wonder how many live in such conditions. Of course, it’s much better than the slums around Mahim. Still, it looks like a rather difficult life.

Yet people manage. I asked a driver a few months ago why he’d migrated to Mumbai. “Livelihood,” was his simple answer. At the end of the day, there are far more well-paying jobs in Mumbai than most other cities. Despite the ridiculous rents and cramped spaces.

Comments

Aparna 16 Aug 2002 12:00 pm: Anand, If someone does not stop the torrential pouring of men in Mumbai, very soon the city will have no space left! Mumbai has close to 29000 people per sq km, can you believe it. I am agitated not amazed. And yes, severely pained for the state of my country’s financial capital.
