parse_transform_serialize_r_block

Parse, transform and serialize a nested parse table

Description

We process blocks of nested parse tables for speed. See cache_find_block() for details on how a top level nest is split into blocks.

Usage

parse_transform_serialize_r_block(
  pd_nested,
  start_line,
  transformers,
  base_indention
)

Arguments

`pd_nested`	A block of the nested parse table.
`start_line`	The line number on which the code starts.
`transformers`	A list of named transformer functions
`base_indention`	Integer scalar indicating by how many spaces the whole output text should be indented. Note that this is not the same as splitting by line and add a `base_indention` spaces before the code in the case multi-line strings are present. See 'Examples'.

Examples

text_in <- 'x<- function()
"here
is"
NULL
1+ 1
'
style_text(text_in, base_indention = 3)
# not equal to the naive approach
styler:::construct_vertical(paste0(styler:::add_spaces(3), style_text(text_in), sep = ""))
