R: Verify the styling

verify_roundtrip {styler} | R Documentation

## Verify the styling

### Description

If scope was set to "line_breaks" or lower (compare `tidyverse_style()`), we can compare the expression before and after styling and return an error if it is not the same. Note that this method ignores comments and no verification can be conducted if scope > "line_breaks".

### Usage

    verify_roundtrip(old_text, new_text)

### Arguments

`old_text` | The initial expression in its character representation.
`new_text` | The styled expression in its character representation.

### Examples

    styler:::verify_roundtrip("a+1", "a + 1")
    styler:::verify_roundtrip("a+1", "a + 1 # comments are dropped")
    ## Not run:
    styler:::verify_roundtrip("a+1", "b - 3")

    ## End(Not run)
