Examples
p <- pip_new("demo") |>
pip_add("numbers", \(n = 5) seq_len(n)) |>
pip_add("squared", \(x = ~numbers) x^2) |>
pip_add("total", \(x = ~squared) sum(x))
p
#> <pipeflow> demo (3 steps)
#> -------------------------
#> step params depends state
#> 1: numbers n new
#> 2: squared x numbers new
#> 3: total x squared new
#> -------------------------
#> <ready> last run: never
str(p)
#> List of 3
#> $ name : chr "demo"
#> $ view : NULL
#> $ pipenv:<environment: 0x5581e72dfae0>
p[["name"]] # "demo"
#> [1] "demo"
p[["view"]] # initially NULL
#> NULL
# Inner pipeline environment (for advanced usage)
ls(p[["pipenv"]]) # shows "data"
#> [1] "data"
ls(p[["pipenv"]], all = TRUE) # also shows hidden variables
#> [1] ".dag" ".last_run" ".restart_count" ".restart_force"
#> [5] ".run_state" ".steps_to_nodes" "data"
