when values_ptypes is provided, the type error uses variable names (#1364)

Code
  pivot_longer(df, x, values_ptypes = character())
Condition
  Error in `pivot_longer()`:
  ! Can't convert `x` <double> to <character>.

when names_ptypes is provided, the type error uses names_to names (#1364)

Code
  pivot_longer(df, cols = x, names_to = "name", names_ptypes = double())
Condition
  Error in `pivot_longer()`:
  ! Can't convert `name` <character> to <double>.

error when overwriting existing column

Code
  pivot_longer(df, y, names_to = "x")
Condition
  Error in `pivot_longer()`:
  ! Names must be unique.
  x These names are duplicated:
    * "x" at locations 1 and 2.
  i Use argument `names_repair` to specify repair strategy.

Code
  out <- pivot_longer(df, y, names_to = "x", names_repair = "unique")
Message
  New names:
  * `x` -> `x...1`
  * `x` -> `x...2`

multiple names requires names_sep/names_pattern

Code
  build_longer_spec(df, x_y, names_to = c("a", "b"))
Condition
  Error in `build_longer_spec()`:
  ! If you supply multiple names in `names_to` you must also supply one of `names_sep` or `names_pattern`.

Code
  build_longer_spec(df, x_y, names_to = c("a", "b"), names_sep = "x",
  names_pattern = "x")
Condition
  Error in `build_longer_spec()`:
  ! If you supply multiple names in `names_to` you must also supply one of `names_sep` or `names_pattern`.

names_sep fails with single name

Code
  build_longer_spec(df, x_y, names_to = "x", names_sep = "_")
Condition
  Error in `build_longer_spec()`:
  ! `names_sep` can't be used with a length 1 `names_to`.

Error if the col can't be selected.

Code
  pivot_longer(iris, matches("foo"))
Condition
  Error in `pivot_longer()`:
  ! `cols` must select at least one column.

named cols gives clear error (#1104)

Code
  pivot_longer(df, c(z = y))
Condition
  Error in `pivot_longer()`:
  ! Can't rename variables in this context.

names_to is validated

Code
  build_longer_spec(df, x, names_to = 1)
Condition
  Error in `build_longer_spec()`:
  ! `names_to` must be a character vector or `NULL`, not the number 1.

Code
  build_longer_spec(df, x, names_to = c("x", "y"))
Condition
  Error in `build_longer_spec()`:
  ! If you supply multiple names in `names_to` you must also supply one of `names_sep` or `names_pattern`.

Code
  build_longer_spec(df, x, names_to = c("x", "y"), names_sep = "_",
  names_pattern = "x")
Condition
  Error in `build_longer_spec()`:
  ! If you supply multiple names in `names_to` you must also supply one of `names_sep` or `names_pattern`.

names_ptypes is validated

Code
  build_longer_spec(df, x, names_ptypes = 1)
Condition
  Error in `build_longer_spec()`:
  ! `names_ptypes` must be `NULL`, an empty ptype, or a named list of ptypes.

Code
  build_longer_spec(df, x, names_ptypes = list(integer()))
Condition
  Error in `build_longer_spec()`:
  ! All elements of `names_ptypes` must be named.

names_transform is validated

Code
  build_longer_spec(df, x, names_transform = 1)
Condition
  Error in `build_longer_spec()`:
  ! `names_transform` must be `NULL`, a function, or a named list of functions.

Code
  build_longer_spec(df, x, names_transform = list(~.x))
Condition
  Error in `build_longer_spec()`:
  ! All elements of `names_transform` must be named.

values_ptypes is validated

Code
  pivot_longer(df, x, values_ptypes = 1)
Condition
  Error in `pivot_longer()`:
  ! `values_ptypes` must be `NULL`, an empty ptype, or a named list of ptypes.

Code
  pivot_longer(df, x, values_ptypes = list(integer()))
Condition
  Error in `pivot_longer()`:

values_transform is validated

Code
  pivot_longer(df, x, values_transform = 1)
Condition
  Error in `pivot_longer()`:
  ! `values_transform` must be `NULL`, a function, or a named list of functions.

Code
  pivot_longer(df, x, values_transform = list(~.x))
Condition
  Error in `pivot_longer()`:
  ! All elements of `values_transform` must be named.

cols_vary is validated

Code
  pivot_longer(df, x, cols_vary = "fast")
Condition
  Error in `pivot_longer()`:
  ! `cols_vary` must be one of "fastest" or "slowest", not "fast".
  i Did you mean "fastest"?

Code
  pivot_longer(df, x, cols_vary = 1)
Condition
  Error in `pivot_longer()`:
  ! `cols_vary` must be a string or character vector.

pivot_longer() catches unused input passed through the dots

Code
  pivot_longer(df, c(x, y), 1)
Condition
  Error in `pivot_longer()`:
  ! Arguments in `...` must be used.
  x Problematic argument:
  * ..1 = 1
  i Did you misspell an argument name?

Code
  pivot_longer(df, c(x, y), col_vary = "slowest")
Condition
  Error in `pivot_longer()`:
  ! Arguments in `...` must be used.
  x Problematic argument:
  * col_vary = "slowest"
  i Did you misspell an argument name?

Code
  build_longer_spec(df, c(x, y), 1)
Condition
  Error in `build_longer_spec()`:
  ! `...` must be empty.
  x Problematic argument:
