parse_transform_serialize_roxygen: Parse, transform and serialize roxygen comments

In styler: Non-Invasive Pretty Printing of R Code

Parse, transform and serialize roxygen comments

Description

Splits text into roxygen code examples and non-roxygen code examples and then maps over these examples by applying style_roxygen_code_example().

Usage

parse_transform_serialize_roxygen(text, transformers, base_indention)

Hierarchy

Styling involves splitting roxygen example code into segments, and segments into snippets. This describes the process for input of parse_transform_serialize_roxygen():

• Splitting code into roxygen example code and other code. Downstream, we are only concerned about roxygen code. See parse_transform_serialize_roxygen().

• Every roxygen example code can have zero or more dontrun / dontshow / donttest sequences. We next create segments of roxygen code examples that contain at most one of these. See style_roxygen_code_example().

• We further split the segment that contains at most one dont* sequence into snippets that are either don* or not. See style_roxygen_code_example_segment().

Finally, that we have roxygen code snippets that are either dont* or not, we style them in style_roxygen_example_snippet() using parse_transform_serialize_r().
