New parse_openapi_spec() and parse_openapi_schema() to convert an
OpenAPI specification to a tibblify specification.
Fix ptype of a tib_vector() inside a tib_df().
New unpack_tspec() to unpack the elements of tib_row() fields (#165).
Improved printing of lists parsed with tspec_object().
Improved performance of the tspec() family.
Improved guessing.
In column major format all fields are required.
Fixed a memory leak.
tib_vector() is now uses less memory and is faster.
tspec_*(), tib_df(), and tib_row() now discard NULL in .... This
makes it easier to add a field conditionally with, for example
tspec_df(if (x) tib_int("a")).
tib_variant() and tib_vector() give you more control for transforming:
transform is now applied to the whole vector.
There is a new elt_transform argument that is applied to every element.
New tspec_recursive() and tib_recursive() to parse tree like structure,
e.g. a directory structure with its children.
Major rewrite of the tibblify package with lots of benefits:
tibblify() is now implemented in C and therefore way faster.
Support of column major format.
Support for vectors as scalar lists and objects.
Specification functions have been renamed
lcols() to tspec_df()tspec_object() and tspec_row()lcol_int() to tib_int() etctspec_df() gains an argument .names_to to store the names of a recordlist
in a column.
Added untibblify() to turn a tibble into a nested list, i.e. to reverse the action of tibblify().
Added spec_combine() to combine multiple specifications.
Added argument unspecified to tibblify() to control how to handle unspecified
fields.
Many bugfixes.
