In krlmlr/styler: Non-Invasive Pretty Printing of R Code

Sets line break after opening parenthesis

Description

Sets line break after opening parenthesis

Usage

set_line_break_after_opening_if_call_is_multi_line(
  pd,
  except_token_after = NULL,
  except_text_before = NULL,
  force_text_before = NULL
)

Arguments

pd	The parse table.
except_token_after	The tokens after the token that cause an exception.
except_text_before	A character vector with text before a token that does not cause a line break.
force_text_before	A character vector with text before "'('" that forces a line break after every argument in the call.

Details

In general, every call that is multi-line has a line break after the opening parenthesis. Exceptions:

• The token right after the parenthesis is a comment, then, the line should be broken after the comment only. Governed by except_token_after.

• The name of the function called is ifelse() or similar, where we can allow the condition on the same line as the function name, and we don't impose rules on the line breaks for the subsequent arguments. Governed by except_text_before.

• Some calls like switch() statements are always forced to become multi- line. Governed by force_text_before.
