feat(ggplot2): add R/ggplot2 library + multi-language pipeline#6944
Merged
Conversation
Wires anyplot for its first non-Python implementation language. Tier 2 / Phase 3 of the library-expansion roadmap — unlocks the R / academic audience and validates the multi-language pipeline.
What's added
- core/constants.py: SUPPORTED_LANGUAGES gains "r", LANGUAGES_METADATA gains the R entry (.R extension, runtime 4.4), SUPPORTED_LIBRARIES + LIBRARIES_METADATA gain ggplot2 with language_id=r
- prompts/library/ggplot2.md: ggplot2-specific generation rules — Okabe-Ito mapping, theme-adaptive chrome tokens, ANYPLOT_THEME env handling, ragg PNG device, NOT_FEASIBLE policy for interactivity
- .github/actions/setup-r: composite action installing R + system libs for ragg/systemfonts, restoring packages from renv.lock, and smoke-testing a ggplot2 render
- renv.lock: pinned ggplot2 + tidyverse helpers + dataset packages (palmerpenguins, gapminder) against a Posit RSPM snapshot
- Frontend CodeHighlighter: registers Prism r grammar, accepts a language prop, falls back to plain text for unknown languages
Workflow changes (extension- and language-aware)
- impl-generate.yml: ggplot2 added to library choices; LANGUAGE + EXT derived from LIBRARY; R setup step conditional on language; version detection via Rscript packageVersion for R libs; all .py paths replaced by ${LIBRARY}${EXT}
- impl-repair.yml: same derive_lang step; conditional R setup; conditional Python plotting deps; extension-aware paths and prompt vars
- impl-review.yml: derives language + ext from library; staging GCS path, metadata path, and impl-file path all use the derived values
- impl-merge.yml: branch parser derives LANGUAGE + EXT from LIBRARY; validates correct impl file path
- bulk-generate.yml: ggplot2 added to choices and ALL_LIBRARIES
- prompts/workflow-prompts/impl-generate-claude.md + impl-repair-claude.md: target paths and run commands made extension-aware (Python uses python, R uses Rscript)
- prompts/plot-generator.md: role/wording generalised; R-specific datasets, reproducibility seed, docstring style, forbidden-patterns list added
Tests
- tests/unit/core/test_constants.py: covers ggplot2 entry, R language metadata, language_id integrity across libraries
- tests/unit/api/test_debug.py + test_routers.py: library_stats length assertions switched to len(SUPPORTED_LIBRARIES) so adding a new library doesn't require a test edit
- app/src/components/CodeHighlighter.test.tsx: covers r language + plain-text fallback
After this lands, gh workflow run impl-generate.yml -f specification_id=<spec> -f library=ggplot2 produces R code and renders plot-light.png / plot-dark.png through the existing review/merge pipeline.
Codecov Report✅ All modified and coverable lines are covered by tests. 📢 Thoughts on this report? Let us know! |
bulk-generate.yml's ALL_LIBRARIES is now 10 (ggplot2 added in the parent commit), and any future addition would re-stale this string.

Pull request overview
This PR introduces the first non-Python plotting library (R/ggplot2) and extends the implementation generation/review/merge pipeline to be language- and extension-aware, enabling end-to-end generation and rendering for multi-language implementations.
Changes:
- Add R + ggplot2 to the backend registry (
SUPPORTED_LANGUAGES,LIBRARIES_METADATA) and extend unit tests accordingly. - Update GitHub Actions workflows and Claude workflow prompts to derive
{LANGUAGE}+{EXT}from{LIBRARY}and useRscript/.Rwhere applicable. - Update the frontend code viewer to syntax-highlight R code and gracefully handle unknown languages.

Three Copilot review comments resolved.
1. python_version no longer abused for R version (impl-generate.yml comment)
- Adds a new language_version column to impls (Alembic migration 3a7e1b5c0c4f), backfilled from python_version for existing rows.
- impl-generate.yml writes both: python_version stays the pipeline Python (3.13), language_version carries the implementation's own runtime — Python for python libs, R for ggplot2.
- sync_to_postgres reads language_version with a fallback to python_version so legacy rows keep displaying correctly.
- API schemas, specs / insights / mcp routers thread the new field through.
- PlotOfTheDay frontend renders {Python|R} {language_version || python_version} so ggplot2 entries show "R 4.4.1" instead of "Python 4.4.1".
2. R header rewrite in impl-review.yml (was Python-only)
- The "Update implementation header" step now branches on LANGUAGE: Python files still get a triple-quoted docstring, R files get a roxygen-style #' block and "R {version}" runtime label.
- If the R file has no existing #' header (e.g. first review pass), one is prepended instead of silently no-op'ing.
3. test_constants docstring lied about library count
- "8 Python + ggplot2" claimed 9 libs but there are 10 (9 Python + 1 R). Length assertion was also redundant with test_contains_expected_libraries, which already checks the exact set.
- Removed the redundant length assertions; the equality check on the expected set is the single source of truth.
Test fixtures (test_routers, test_tools, PlotOfTheDay tests) updated to set the new language_version attribute so Pydantic validation passes.
…uage Audit pass on PR #6944. Adds R/ggplot2 coverage to the surface areas the parent commits missed. Docs (no behavioural change, only counts and wording) - README, agentic/docs/project-guide.md, docs/concepts/vision.md, docs/concepts/library-expansion.md, docs/reference/style-guide.md, docs/reference/tagging-system.md, docs/reference/repository.md, prompts/README.md: every "9 libraries" / "nine ecosystems" line either generalised to "10 libraries (Python + R)" or rewritten so the count is derived from the canonical list. - library-expansion.md: Phase 3 marked as shipped in the rollout table; current-state line now reads "9 Python + 1 R". Prompts (extend Python-only assumptions) - prompts/quality-evaluator.md: role line generalised; code path uses {ext}; static-library lists include ggplot2. - prompts/workflow-prompts/ai-quality-review.md: implementation path uses {EXT}; static-library AR-08 check includes ggplot2. - prompts/workflow-prompts/impl-similarity-claude.md: sibling-source paths are no longer hardcoded to python/.py; uses {language}/{library}{ext}. Frontend - SpecPage SEO schema.org JSON-LD: programmingLanguage now maps r -> "R" (was lowercase, which downgrades SEO). Scripts - scripts/evaluate-plot.py: get_plot_paths picks the right file extension per language; the CLI exits cleanly for ggplot2 (Python-only AST + Rscript runner are out of scope for the local evaluator — directs users to the CI workflow).
The two r-lib/actions references were pinned to a SHA I fabricated. GitHub would have rejected the workflow at first run with "unable to resolve action". Switched to @v2 (the maintained moving tag for r-lib/actions). Dependabot will pin it to a real SHA on its next run, consistent with the rest of the repo's pinning policy. Also threaded RENV_CONFIG_INSTALL_HASHES=FALSE to setup-renv so the hand-written hash-less lockfile restores without renv refusing. The pinned Posit RSPM snapshot URL in renv.lock provides reproducibility; once CI's first successful run regenerates renv.lock with hashes, the flag can drop.

Two more review comments on commit a07b6f2: 1. PlotOfTheDay still had hardcoded `python` + `.py` in the source-link href and the displayed command string — only the runtime label rendering was language- aware. If POTD ever picks ggplot2 the GitHub link 404s and the chip lies about how to run the file. Now derives `ext` and `runner` from `data.language`, so the chip flips to `Rscript plots/.../ggplot2.R` and the GitHub URL points at the .R file. PlotOfTheDayTerminal had the same bug (it builds the same filename + GitHub URL) — fixed alongside. 2. scripts/evaluate-plot.py was duplicating the language->extension mapping with a local ternary and keyed the skip off `library == "ggplot2"` instead of the underlying language. Now imports LANGUAGE_FILE_EXTENSIONS from core.constants (single source of truth shared with sync_to_postgres) and skips any non-python library generically — automatically covers future R/JS/Julia entries without another edit. SUPPORTED_LIBRARIES is now derived from LIBRARIES_METADATA filtered by language_id=python, so it can't drift.

## Summary Three Copilot review comments arrived on #6944 just before/after it was merged. Picking up the actionable ones in a small follow-up. ## What's fixed **1. `PlotOfTheDayTerminal` — hardcoded `python` prompt** (#discussion_r3253434308) The terminal-style chip in the POTD card had a hardcoded `python` label even though the filename now flips to `.R` for ggplot2. Output would read `python plots/<spec>/ggplot2.R` — wrong. Now derives a `runner` token from `potd.language` (`Rscript` for `r`, `python` otherwise) alongside the existing `ext` switch. **2. `prompts/plot-generator.md` — contradictory docstring rule** (#discussion_r3253434312) The "Forbidden (Python)" list said *"Type hints or docstrings (keep it simple)"* while the same prompt elsewhere requires a 4-line module-header docstring at the top of every Python impl. Contradictory guidance can make generators omit the required header. Clarified: header docstring is mandatory, additional docstrings are forbidden. Added the R equivalent for roxygen `#'` blocks so the rule symmetric. **3. `impl-review.yml` — Python header rewrite needs a prepend fallback** (#discussion_r3253434319) The Python branch of the header-rewrite step ran `re.sub` on a triple-quoted docstring pattern and silently left the file unchanged if there was no header. Mirrors the R branch behaviour now: `re.match` first, prepend the canonical header if absent. ## Deliberately *not* in this PR - **SHA-pinning `r-lib/actions/setup-r` and `setup-renv`** (#discussion_r3253434287, #discussion_r3253434297). Pinning is correct policy, but pushing a SHA I haven't verified would re-introduce the bogus-SHA blocker that #6944 already had to fix. Dependabot will pin them to a verified SHA on its next run, the same way every other action ref in the repo got there. ## Test plan - [x] `python3 -c "import yaml; ..."` on impl-review.yml — parses - [ ] CI: ci-lint, ci-tests, frontend tsc + vitest - [ ] One real impl-review run that exercises the Python prepend fallback (will happen organically the next time a Python impl is reviewed) https://claude.ai/code/session_01Kb7b7QZi3ohtSTbd39poFV --- _Generated by [Claude Code](https://claude.ai/code/session_01Kb7b7QZi3ohtSTbd39poFV)_ Co-authored-by: Claude <noreply@anthropic.com>

…anguages count (#6961) Three R/ggplot2 rollout gaps surfaced after [PR #6951](#6951) merged. All show wrong data despite the DB row being correct — they were always going to need a follow-up after the first non-Python impl landed. ## 1. Code viewer empty on `/scatter-basic/r/ggplot2` \`ImplRepository.get_code()\` has signature \`get_code(spec_id, library_id, language_id=\"python\")\`. The \`/specs/{spec_id}/{library}/code\` endpoint never accepted a language and never passed one through — so R rows (\`language_id=\"r\"\`) failed the WHERE clause, the endpoint returned 404, and the frontend showed a blank code panel. \`\`\`bash $ curl -s -o /dev/null -w \"%{http_code}\\n\" https://anyplot.ai/api/specs/scatter-basic/matplotlib/code 200 $ curl -s -o /dev/null -w \"%{http_code}\\n\" https://anyplot.ai/api/specs/scatter-basic/ggplot2/code 404 \`\`\` **Fix:** - **API:** \`get_impl_code\` accepts \`?language=\` (default \`\"python\"\` for backwards compat). \`_build_impl_code\` and the Redis cache key both include language so Python and R impls under the same library_id can't collide. - **Frontend:** \`useCodeFetch\` accepts an optional \`language\` arg, includes it in the in-memory cache key, and only appends \`?language=\` to the URL when it diverges from python — Python URLs and existing tests stay unchanged. - **SpecPage:** passes \`urlLanguage\` (already destructured from \`useParams\`) to \`fetchCode\`/\`getCode\`, and \`impl.language\` to the copy-to-clipboard path. ## 2. Landing strip shows \"languages: 1\" \`NumbersStrip.tsx\` line 16 was \`{ value: '1', label: 'languages' }\` — literally hardcoded, never wired to any stat. **Fix:** - **API:** add \`languages: int = 0\` to \`StatsResponse\`. \`_refresh_stats\` and the cached \`_fetch\` factory derive it from \`{lib.language_id for lib in libraries}\` (with a \`len(LANGUAGES_METADATA)\` fallback when libraries are unavailable, mirroring how libraries count already worked). - **Frontend:** bind to \`stats.languages\` with an em-dash fallback while loading. ## 3. ggplot2 missing from `/libraries` \`app/src/constants/index.ts\` had: \`\`\`ts export const LIBRARIES = ['altair', 'bokeh', 'highcharts', 'letsplot', 'matplotlib', 'plotly', 'plotnine', 'pygal', 'seaborn']; \`\`\` LibrariesPage iterates this list to render cards, so ggplot2 was silently skipped even though \`/api/libraries\` already returned it. **Fix:** add \`'ggplot2'\` to \`LIBRARIES\` (alpha order, between bokeh and highcharts) and \`'gg'\` to \`LIB_ABBREV\` for compact display. ## Test plan - [x] \`useCodeFetch.test.ts\` — 12/12 green (10 existing + 2 new: \`?language=\` is appended for non-python, separate cache keys per language for same library_id) - [x] \`tests/unit/api/test_stats.py\` — green, asserts \`languages == 1\` for the mocked single-library case - [x] \`tests/unit/api/test_schemas.py\` — green, \`languages\` field present in \`model_dump()\` - [x] \`tests/unit/api/test_routers.py\` — 8/8 code-endpoint tests still pass (default-python path unchanged) - [ ] After deploy: \`curl https://anyplot.ai/api/specs/scatter-basic/ggplot2/code?language=r\` returns 200 with the R source - [ ] After deploy: \`/libraries\` shows ggplot2 card, landing strip shows \`languages: 2\` ## Out of scope (separate issues) - Issue #6958 — language is not shown in plot image titles (\`scatter-basic · ggplot2 · anyplot.ai\` is ambiguous for R vs Python libs); design decision pending - Pre-existing TS error in \`CodeHighlighter.tsx:3\` for the R syntax-highlighter import (\`@types/react-syntax-highlighter\` doesn't declare \`prism/r\`) — was introduced by PR #6944, not by this PR 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Why The frontend changes from [PR #6961](#6961) — `languages` count on the landing strip, ggplot2 card on `/libraries`, R code viewer on `/scatter-basic/r/ggplot2` — are merged on `main`, but production still shows the pre-#6961 state: ```bash $ curl -s https://anyplot.ai/assets/constants-Cv1rI8LA.js | head -c 200 …LIBRARIES=['altair','bokeh','highcharts',…] # no ggplot2 $ curl -s https://anyplot.ai/assets/LandingPage-Bluw1eOY.js | grep -oE '.{20}languages.{20}' …children:[{value:`1`,label:`languages`}… # hardcoded '1' ``` All served assets carry `last-modified: Sat, 16 May 2026 20:04:15 GMT` — about 2.5 h **before** #6961 merged. The API was redeployed (`/stats` now returns `"languages":2,"libraries":10`), but the frontend Cloud Run revision is stale. ## Root cause The frontend Cloud Build (`app/cloudbuild.yaml` → `yarn build` = `tsc && vite build`) fails at the `tsc` step: ``` src/components/CodeHighlighter.tsx(3,15): error TS7016: Could not find a declaration file for module 'react-syntax-highlighter/dist/esm/languages/prism/r'. '…/react-syntax-highlighter/dist/esm/languages/prism/r.js' implicitly has an 'any' type. ``` `@types/react-syntax-highlighter` actually does ship an ambient declaration for this exact path (line 2768 of its `index.d.ts`), but with `moduleResolution: "bundler"` tsc resolves the import to the sibling `.js` file first and never reaches the @types index — only `r` trips, `python` from the line above happens to resolve through the cached package types. Net effect: `tsc` exits non-zero, `vite build` never runs, no new Docker layer, Cloud Run keeps serving the previous revision. Docker build log confirmed this: ``` ERROR: build step 0 "gcr.io/cloud-builders/docker" failed: step exited with non-zero status: 2 The command '/bin/sh -c yarn build' returned a non-zero code: 2 ``` PR #6961 listed this exact TS error under "Out of scope" — it had been latent since #6944 added the R import, and only became a deploy blocker because #6961 was the first frontend-touching PR after the lib bumps that affect tsc behavior. ## Fix Add `app/src/types/react-syntax-highlighter.d.ts` declaring the missing module locally. A project-local shim wins over `@types`, which is enough to unblock `tsc`. The runtime import is unchanged — Prism still registers the real R grammar via `registerLanguage('r', r)`, and a grep over the rebuilt `CodeHighlighter-*.js` confirms the R keyword set is bundled: ``` break|else|for|function|if|in|next|repeat|while ``` So R syntax highlighting on `/scatter-basic/r/ggplot2` works as intended. ## Test plan - [x] `cd app && yarn build` — green (was failing on TS7016 before) - [x] `cd app && yarn test` — 459/459 green - [x] New bundle hash differs from the deployed one (`LandingPage-e58y3raq.js` vs prod `LandingPage-Bluw1eOY.js`), confirming the redeploy will publish fresh assets - [ ] After merge: Cloud Build for `anyplot-app` finishes green; `https://anyplot.ai/assets/LandingPage-*.js` no longer contains the hardcoded `{value:'1',label:'languages'}` - [ ] After deploy: landing strip shows `languages: 2`, `/libraries` shows the ggplot2 card, `/scatter-basic/r/ggplot2` code panel renders R code with highlighting ## Notes - This PR does **not** re-introduce the language count / ggplot2 / R-code-viewer logic — those landed in #6961 and are already on main. This only removes the build blocker so the existing fixes can actually reach production. - The Cloud Build "deploy-app (anyplot) ✅ Passed" check that appeared on #6961's merge commit was from `.github/workflows/notify-deployment.yml`, which is a no-op `echo` step that records a GitHub Deployment object — it does not actually report the GCP Cloud Build outcome. Worth a follow-up to either wire the real Cloud Build status back to the commit or rename the workflow so the green check doesn't mislead. --- _Generated by [Claude Code](https://claude.ai/code/session_01DdvT6aZxMm5QKU4jd8afUr)_ --------- Co-authored-by: Claude <noreply@anthropic.com>

renv.lockis committed without per-packageHashfields.renv::restore()falls back to installing the pinnedVersionfrom the RSPM snapshot, so reproducibility comes from the URL pin.
