transform_and_check: Transform a file an check the result

In styler: Non-Invasive Pretty Printing of R Code

Transform a file an check the result

Description

Transform an file and check whether it is identical to a reference.

Usage

transform_and_check(
  in_item,
  out_item,
  in_name = in_item,
  out_name = out_item,
  transformer,
  dry,
  write_tree = NA,
  out_tree = "_tree",
  ...
)

Arguments

in_item	An path to an file to transform.
out_item	The path to a file that contains the expected result.
in_name	The label of the in_item, defaults to in_item.
out_name	The label of the out_item, defaults to out_item.
transformer	A function to apply to the content of in_item.
dry	To indicate whether styler should run in dry mode, i.e. refrain from writing back to files ."on" and "fail" both don't write back, the latter returns an error if the input code is not identical to the result of styling. "off", the default, writes back if the input and output of styling are not identical.
write_tree	Whether or not the tree structure of the test should be computed and written to a file. Note that this needs R >= 3.2 (see set_arg_write_tree()). If the argument is set to NA, the function determines whether R >= 3.2 is in use and if so, trees will be written.
out_tree	Name of tree file if written out.
...	Parameters passed to transformer function.
