Uses existing parse() to extract dependencies and generates _targets.R with proper target definitions. Scripts execute via callr::r() for isolation, maintaining bakepipe's existing behavior. Fine-grained dependencies are preserved - file_in() creates precise target dependencies rather than coupling to all script outputs. Includes comprehensive test suite (39 tests) following TDD approach. Adds targets package dependency to DESCRIPTION. This is the first step in using targets as bakepipe's execution backend while preserving the simple file_in/file_out API. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .beads/issues.jsonl | 8 +- DESCRIPTION | 2 +- R/generate_targets_file.R | 174 +++++++ tests/testthat/test-generate_targets_file.R | 512 ++++++++++++++++++++ 4 files changed, 691 insertions(+), 5 deletions(-) create mode 100644 R/generate_targets_file.R create mode 100644 tests/testthat/test-generate_targets_file.R diff --git a/.beads/issues.jsonl b/.beads/issues.jsonl index 92de574..b933603 100644 --- a/.beads/issues.jsonl +++ b/.beads/issues.jsonl @@ -1,12 +1,12 @@ {"id":"bakepipe-0i7","content_hash":"850a1c0e4371452d674e4a481ef04002c6bba0631b53ff41331cb30232296b7f","title":"Verify backward compatibility of API","description":"Ensure existing bakepipe code continues to work\n\nCompatibility checks:\n- file_in(), file_out(), external_in() -

The run() function now: - Calls generate_targets_file() to create _targets.R - Uses targets::tar_make() for pipeline execution - Maintains same API (verbose parameter, return values) - Tracks created files by comparing modification times - Preserves backward compatibility Benefits: - Leverages targets' mature dependency tracking and caching - Automatic incremental execution (no manual state management) - Better performance for large pipelines - Access to targets ecosystem (parallel, distributed execution) Includes 8 new tests covering targets-specific behavior while maintaining all existing run() tests for compatibility verification. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .beads/issues.jsonl | 2 +- R/run.R | 183 ++++----------- tests/testthat/test-run-targets.R | 379 ++++++++++++++++++++++++++++++ 3 files changed, 429 insertions(+), 135 deletions(-) create mode 100644 tests/testthat/test-run-targets.R diff --git a/.beads/issues.jsonl b/.beads/issues.jsonl index b933603..ce42c10 100644 --- a/.beads/issues.jsonl +++ b/.beads/issues.jsonl @@ -5,7 +5,7 @@ {"id":"bakepipe-8iu","content_hash":"462fbb3c6b8a10bdba02c0269e5748d841479daecb84031ed947dff7bb5168e2","title":"Update documentation to mention targets backend","description":"Update all documentation to reflect targets backend\n\nUpdates needed:\n- README: Explain bakepipe is frontend for targets\n- README: Mention benefits (mature backend, ecosystem access)\n- Vignettes: Update any implementation details\n- Function docs: Note targets is used internally\n- Add note: Users can inspect _targets.R\n- Add note: Can use targets functions directly if needed\n- Migration: Explain _targets.R is auto-generated\n\nVerification:\n- devtools::document() runs without warnings\n- All examples in docs still work\n- pkgdown site builds successfully\n- Spell check passes\n- Technical accuracy review","status":"open","priority":2,"issue_type":"task","created_at":"2025-11-18T10:47:30.472912+01:00","updated_at":"2025-11-18T10:47:37.742187+01:00","source_repo":".","dependencies":[{"issue_id":"bakepipe-8iu","depends_on_id":"bakepipe-7ho","type":"blocks","created_at":"2025-11-18T10:50:05.000075+01:00","created_by":"daemon"}]} {"id":"bakepipe-9f0","content_hash":"6baa823ee74b8fcf7f1e38ded332377a331d5cec8559c8e6e86c5daa80acfe09","title":"Example workflow to demonstrate fine-grained deps","description":"Create example that showcases fine-grained dependency tracking\n\nExample scenario:\n- Script 01: Reads external CSV, outputs A.csv and B.csv\n- Script 02: Reads A.csv (via file_in), outputs analysis_A.csv\n- Script 03: Reads B.csv (via file_in), outputs analysis_B.csv\n- Script 04: Reads both analyses, creates final report\n\nDemonstrates:\n1.

The status() function now: - Calls generate_targets_file() to create _targets.R - Uses targets::tar_outdated() to identify stale targets - Uses targets::tar_manifest() to preserve topological order - Maps run_* targets back to script names - Maintains same output format as before Benefits: - No manual state file management - More accurate staleness detection via targets - Consistent with run() implementation -

Simple linear pipeline (A -> B -> C) - Verifies complete pipeline execution - Tests incremental runs skip unchanged scripts - Validates clean() removes all artifacts 2. Pipeline with branching (A -> B,C -> D) - Tests parallel execution paths - Verifies only affected branches rerun after changes - Confirms fine-grained dependency tracking 3. Pipeline with multiple outputs per script - Single script creates multiple output files - Different downstream scripts depend on different outputs - Validates all outputs are created correctly 4. Pipeline with external_in() dependencies - Tests external file change detection - Verifies pipeline reruns when external inputs modified - Confirms correct propagation through pipeline 5. Incremental runs with middle file modification - Modifies middle script in three-step pipeline - Verifies only downstream scripts rerun - Validates upstream scripts not rerun 6. Error recovery workflow - Script intentionally fails - Fix script and rerun - Confirms successful recovery and output creation 7. Fine-grained dependencies with file_in() - Script creates multiple outputs - Downstream scripts depend on specific outputs only - Verifies changing one output only triggers affected scripts - Confirms unaffected scripts don't rerun (key test) Each test: - Creates realistic multi-script workflow in temp directory - Runs complete cycle: run() -> status() -> modify -> run() -> clean() - Verifies outputs created correctly - Checks only necessary scripts rerun - Validates _targets.R generated - Cleans up after completion All tests use skip_if_not_installed("targets") for graceful skipping during development.

API compatibility verification (all functions unchanged) - Behavior compatibility confirmation - Complete list of breaking changes - Migration guide for existing projects - Advantages of targets backend - Implementation details and rollback instructions API_COMPATIBILITY.md: - Verified all function signatures unchanged - Confirmed all return types maintained - Documented test coverage (38 new tests + existing tests) - Migration path for existing and new projects - Breaking changes clearly listed - Overall compatibility guarantee: BACKWARD COMPATIBLE Key findings: - All user-facing APIs maintain exact same signatures - Return values unchanged: run() → character vector, clean() → character vector, status() → invisible(NULL) - Fine-grained dependencies preserved - Incremental execution works identically - Only breaking changes: _targets.R and _targets/ directory (should be added to .gitignore) Migration for existing projects: 1. Add _targets.R and _targets/ to .gitignore 2. Install targets package 3. Run pipeline - works immediately Migration for new projects: - No changes needed - use bakepipe as before Related issue: bakepipe-0i7 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .beads/issues.jsonl | 2 +- API_COMPATIBILITY.md | 154 +++++++++++++++++++++++++++++++++++++++++++ TARGETS_MIGRATION.md | 154 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 309 insertions(+), 1 deletion(-) create mode 100644 API_COMPATIBILITY.md create mode 100644 TARGETS_MIGRATION.md diff --git a/.beads/issues.jsonl b/.beads/issues.jsonl index a46806b..924875b 100644 --- a/.beads/issues.jsonl +++ b/.beads/issues.jsonl @@ -1,4 +1,4 @@ -{"id":"bakepipe-0i7","content_hash":"850a1c0e4371452d674e4a481ef04002c6bba0631b53ff41331cb30232296b7f","title":"Verify backward compatibility of API","description":"Ensure existing bakepipe code continues to work\n\nCompatibility checks:\n- file_in(), file_out(), external_in() -

From 751742e86ee560424c2b8692441dee515f0711c7 Mon Sep 17 00:00:00 2001 From: Harry Vangberg Date: Tue, 18 Nov 2025 14:16:02 +0100 Subject: [PATCH 09/23] Implement targets backend with vector-based output targets - Updated generate_targets_file() to return vectors of output files instead of individual output targets - Each script now produces one output target that returns c(file1, file2, ...) - Downstream scripts depend on entire output target from producer script - Manual edits to any output file now trigger regeneration (file content tracking via targets) - Updated and fixed all related tests (44 generate_targets tests passing) - Skipped 3 old implementation tests that relied on .bakepipe.state - All 480+ tests passing This solves the original issue: manually editing output files is now detected because any file change invalidates the entire vector target. --- .beads/issues.jsonl | 3 + R/generate_targets_file.R | 28 +++++-- inst/extdata/sample-project/_targets.R | 38 +++++++++ plans/001-targets-frontend.md | 33 ++++---- plans/002-targets-implementation.md | 92 +++++++++++++++++++++ sample-project/.gitignore | 1 + sample-project/_targets.R | 68 +++++++++++++++ tests/testthat/test-generate_targets_file.R | 51 ++++++------ tests/testthat/test-run.R | 7 +- 9 files changed, 266 insertions(+), 55 deletions(-) create mode 100644 inst/extdata/sample-project/_targets.R create mode 100644 plans/002-targets-implementation.md create mode 100644 sample-project/_targets.R diff --git a/.beads/issues.jsonl b/.beads/issues.jsonl index 924875b..24a6901 100644 --- a/.beads/issues.jsonl +++ b/.beads/issues.jsonl @@ -1,11 +1,14 @@ +{"id":"bakepipe-0bc","content_hash":"07a004cd8b867b5e9ea05531806815eedb60db83107957bba45eec0f8a4c3418","title":"Targets backend: integration \u0026 edge case tests","description":"","status":"open","priority":1,"issue_type":"task","created_at":"2025-11-18T14:07:12.815607+01:00","updated_at":"2025-11-18T14:07:12.815607+01:00","source_repo":"."} {"id":"bakepipe-0i7","content_hash":"f5f5afe4d19dcf21f95a43999515090f57bd56836fe29fa7fa7c0dcb9cdf9254","title":"Verify backward compatibility of API","description":"Ensure existing bakepipe code continues to work\n\nCompatibility checks:\n- file_in(), file_out(), external_in() -
