styler (version 1.6.1)

verify_roundtrip: 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 roxygen code examples and comments and no verification can be conducted if tokens are in the styling scope.

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

# NOT RUN {
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")
# }
