needs_indention_one: Check whether indention is needed

In styler: Non-Invasive Pretty Printing of R Code

Check whether indention is needed

Description

Determine whether the tokens corresponding to potential_trigger_pos should cause indention, considering that there might be other potential triggers other_trigger_tokens that are going to cause indention. Indention is needed if the two conditions apply:

Usage

needs_indention_one(pd, potential_trigger_pos, other_trigger_tokens)

Arguments

pd	A parse table.
potential_trigger_pos	the index of the token in the parse table for which it should be checked whether it should trigger indention.
other_trigger_tokens	Other tokens that are going to cause indention if on the same line as the token corresponding to potential_trigger and directly followed by a line break.

Details

• there is no multi-line token between the trigger and the first line break.

• there is no other token between the potential trigger and the first line break that is going to cause indention. Note that such an other trigger only causes indention if there is a line break after that other triggering token, not otherwise. If it causes indention, it is said to be an active trigger, if it does not, it is called an inactive trigger. See 'Details' for an example where there is an other trigger token, but since the next token is on the same line as the other trigger, the trigger is passive.

Value

Returns TRUE if indention is needed, FALSE otherwise.

TRUE if indention is needed, FALSE otherwise.

Examples

style_text(c(
  "call(named = c,",
  "named = b)"
), strict = FALSE)
