identify_raw_chunks: Identifies raw Rmd or Rnw code chunks

In styler: Non-Invasive Pretty Printing of R Code

Identifies raw Rmd or Rnw code chunks

Description

Raw in the sense that these chunks don't contain pure R code, but they contain a header and footer of markdown. Only code chunks that have an engine whose name matches engine-pattern are considered as R code. For every opening, we match the next closing. If there are not the same amount of closing and openings after this matching, we throw an error. Similarly, if there are two openings before a closing, the closing gets matched twice, on which we throw an error.

Usage

identify_raw_chunks(lines, filetype, engine_pattern = get_engine_pattern())

Arguments

lines	A character vector of lines from an Rmd or Rnw file.
filetype	A string indicating the filetype - either 'Rmd' or 'Rnw'.
engine_pattern	A regular expression that must match the engine name.
