The effect of strict = FALSE

This vignette shows how output from styler might differ when strict = FALSE. For brevity, we don’t show the output of strict = TRUE, but it should be pretty simple for the user to derive it from the bullet point(s) or simply paste the code in the console to see the output.

library(styler)

• multi-line function declarations without curly braces are tolerated.

function()
  NULL

• Spaces before opening parenthesis, tilde as well as around comments and math token must be at least one, not exactly one.

1  +    (1 + 3)
1 ~  more()   #   comment

• More than one line break is tolerated before closing curly brace and line breaks between curly and round braces are not removed.

test({
  1

}
)

• Multi-line calls don’t put the closing brace on a new line nor trigger a line break after the opening brace.

call(
  this)
call(2,
  more
)

• No line break inserted after pipes nor ggplot2 or pipe expressions.

ggplot2::ggplot(data, aes(x, y)) + geom_line() + scale_x_continuous()

this %>% is() %>% a() %>% long() %>% pipe()

• ifelse statements don’t get curly braces added when multi-line.

if (TRUE) 3  else
