Unpack a tibblify specification

Description

Unpack a tibblify specification

Usage

unpack_tspec(
  spec,
  ...,
  fields = NULL,
  recurse = TRUE,
  names_sep = NULL,
  names_repair = c("unique", "universal", "check_unique", "unique_quiet",
    "universal_quiet"),
  names_clean = NULL
)

camel_case_to_snake_case(names)

Arguments

spec	A tibblify specification.
...	These dots are for future extensions and must be empty.
fields	A string of the fields to unpack.
recurse	Should unpack recursively?
names_sep	If NULL, the default, the inner names of fields are used. If a string, the outer and inner names are pasted together, separated by names_sep.
names_repair	Used to check that output data frame has valid names. Must be one of the following options: "unique" or "unique_quiet": (the default) make sure names are unique and not empty, ⁠"universal" or ⁠"unique_quiet"': make the names unique and syntactic "check_unique": no name repair, but check they are unique, a function: apply custom name repair. See vctrs::vec_as_names() for more information.
names_clean	A function to clean names after repairing. For example use camel_case_to_snake_case().
names	Names to clean

Value

A tibblify spec.

Examples

spec <- tspec_df(
  tib_lgl("a"),
  tib_row("x", tib_int("b"), tib_chr("c")),
  tib_row("y", tib_row("z", tib_chr("d")))
)

unpack_tspec(spec)
# only unpack `x`
unpack_tspec(spec, fields = "x")
# do not unpack the fields in `y`
unpack_tspec(spec, recurse = FALSE)
