pipeflow 0.3.0
New features
- C++ DAG engine (
src/dag.cpp): All
graph operations (node/edge add/remove, topological ordering,
reachability queries) run at C++ speed via Rcpp, eliminating R object
overhead for dependency resolution.
- New
pip_* API: Functional API
replacing the R6 Pipeline class — pip_new(),
pip_add(), pip_run(),
pip_replace(), pip_clone(),
pip_bind(), pip_view(),
pip_tag()/pip_untag(), etc.
- Execution modes
(
auto/split/reduce/plain):
Native support for map-reduce style workflows where steps split output
into named partitions and downstream steps auto-map over them.
- Dependency validation at definition time:
pip_add(), pip_replace(), and
pip_remove() fail fast on broken references.
- New pkgdown-only article pipeflow vs targets
(
vignettes/articles/v07-vs-targets.Rmd) with an 18-row
feature comparison table and benchmarks.
Breaking changes
- Legacy
pipe_* functions and Pipeline R6
class are deprecated (preserved as aliases in R/aliases.R,
R/pipelineR6.R).
pip_collect_out() no longer accepts
grouped or by parameters. It returns a flat
named list of step outputs. Use pip_view() with tags and
manual list composition for grouped output.- The
group column has been removed from the pipeline
data.table. Steps previously using group = "..." in
pip_add() should use tags = "...".
Documentation
- Comprehensive revision of all vignettes to match the new
pip_* API.
- Revised
vignettes/v04-collect-output.Rmd to demonstrate
tag-based grouping via pip_view() composition.
- Updated README with a “Why use {pipeflow}” feature list, a short
usage example, and a revised vs-targets summary.
Internal
- Extensive test suite covering C++ DAG,
pip_* API,
aliases, execution modes, and recursive runs.
- MIT license, updated CI workflows, dependabot config, kilo.json,
lintr/styler config.
