rixpress 0.12.1 (2026-02-04)

Improvements

  • Python Version Detection: rixpress now correctly detects the Python version specified in default.nix (e.g., python311Packages, python312Packages) and uses the corresponding interpreter (e.g., ${defaultPkgs.python311}/bin/python) instead of defaulting to python3. This prevents ABI version mismatch errors when using compiled Python packages like numpy.

rixpress 0.12.0 (2026-01-31)

New Features

  • Chronicler integration: Added support for detecting {chronicler} package Nothing values in pipeline outputs. When using chronicler’s record() decorated functions, errors and warnings are captured as Nothing values instead of failing the build. This can mask pipeline failures.

  • rxp_check_chronicles(): New function to scan all pipeline outputs for chronicle objects and report their status:

    • ✓ Success: Just value, no warnings or errors
    • ⚠ Warning: Just value, but warnings were captured
    • ✗ Nothing: Failed computation, errors captured

  • Enhanced rxp_read() and rxp_load(): Now automatically warn when reading chronicle objects that contain Nothing values, and inform about chronicles with captured warnings.

Internal Changes

  • Added chronicler as an optional dependency (Suggests).
  • New internal helper functions for chronicle state detection.

rixpress 0.11.2 (2026-01-28)

CRAN release: 2026-01-28

Changes

  • Updated rxp_visnetwork() styling to use a dual-encoding approach (similar to rxp_ggdag()) when color_by = "pipeline". Now, node interiors are colored by derivation type (e.g., R, Python) while node borders are colored by pipeline group.
  • Spellchecked vignettes/sub-pipelines.Rmd to British English. # rixpress 0.11.1 (2026-01-25)

Bug Fixes

  • Fixed parsing of default.nix files when Python packages are installed from git. Previously, rixpress failed to parse the pyconf block correctly when it contained the } ++ [ ... ]; syntax used by rix for git packages.

rixpress 0.11.0 (2025-01-24)

New Features

  • Sub-pipelines with rxp_pipeline(): New function to organize derivations into named logical groups (e.g., “ETL”, “Model”, “Report”). Pipeline groups are visually distinguished in DAG visualizations with custom colors.

  • Pipeline-based DAG coloring: rxp_visnetwork() and rxp_ggdag() now support a color_by parameter. When set to “pipeline” (the default when pipelines are defined), nodes are colored by their pipeline group rather than derivation type.

  • Master Script workflow: Enables organizing large projects across multiple R scripts, then combining them in a master script using rxp_pipeline().

Internal Changes

  • rxp_populate() now flattens rxp_pipeline objects while preserving metadata.
  • dag.json schema extended with pipeline_group and pipeline_color fields.
  • get_nodes_edges() extracts pipeline metadata for visualization.

Bug Fixes

  • Relative paths for nix_env (e.g., "../../default.nix") now work correctly. Previously, path characters were converted to underscores, causing invalid Nix variable names like ______defaultBuildInputs. Now only the filename is used, producing valid identifiers like defaultBuildInputs.
