Printing tibblify specifications

Description

The print() and format() methods for tibblify specifications provide the code necessary to generate the specification. Function names are color-coded to help visually distinguish different types of collectors.

Usage

## S3 method for class 'tib_collector'
print(x, width = NULL, ..., names = NULL)

## S3 method for class 'tib_scalar'
format(
  x,
  ...,
  .fill = NULL,
  .ptype_inner = NULL,
  .transform = NULL,
  multi_line = FALSE,
  nchar_indent = 0,
  width = NULL,
  names = FALSE
)

## S3 method for class 'tib_variant'
format(x, ..., multi_line = FALSE, nchar_indent = 0, width = NULL)

## S3 method for class 'tib_vector'
format(x, ..., multi_line = FALSE, nchar_indent = 0, width = NULL)

## S3 method for class 'tib_unspecified'
format(
  x,
  ...,
  .fill = NULL,
  .ptype_inner = NULL,
  .transform = NULL,
  multi_line = FALSE,
  nchar_indent = 0,
  width = NULL,
  names = FALSE
)

## S3 method for class 'tib_scalar_chr_date'
format(x, ..., multi_line = FALSE, nchar_indent = 0, width = NULL)

## S3 method for class 'tib_vector_chr_date'
format(x, ..., multi_line = FALSE, nchar_indent = 0, width = NULL)

## S3 method for class 'tib_row'
format(x, ..., width = NULL, names = NULL)

## S3 method for class 'tib_df'
format(x, ..., width = NULL, names = NULL)

## S3 method for class 'tib_recursive'
format(x, ..., width = NULL, names = NULL)

## S3 method for class 'tibblify_object'
print(x, ...)

## S3 method for class 'tspec'
print(x, width = NULL, ..., names = NULL)

## S3 method for class 'tspec_df'
format(x, width = NULL, ..., names = NULL)

## S3 method for class 'tspec_row'
format(x, width = NULL, ..., names = NULL)

## S3 method for class 'tspec_recursive'
format(x, width = NULL, ..., names = NULL)

## S3 method for class 'tspec_object'
format(x, width = NULL, ..., names = NULL)

Arguments

x	(any) The spec to format or print.
width	(integer(1)) The width (in number of characters) of text output to generate.
...	These dots are for future extensions and must be empty.
names	(logical(1)) Should names be printed even if they can be deduced from the spec?
.fill	(vector or NULL) Optionally, a value to use if the field does not exist. Note: this value must match the .ptype_inner of the field (the value before any transformation), not the .ptype.
.ptype_inner	(vector(0)) A prototype of the input field.
.transform	(function or NULL) A function to apply to the whole vector after casting to .ptype_inner.
multi_line	(logical(1)) Should the output be formatted across multiple lines? For example, should each element of even a short list be displayed on its own line?
nchar_indent	(integer(1)) The number of (additional) characters that will be used to indent the output when multi_line = TRUE. Primarily for internal use when formatting is applied recursively.

Value

For print() methods, x is returned invisibly. format() methods return a length-1 character vector.

Examples

spec <- tspec_df(
  a = tib_int("a"),
  new_name = tib_chr("b"),
  row = tib_row(
    "row",
    x = tib_int("x")
  )
)
print(spec, names = FALSE)
print(spec, names = TRUE)
