{ gets bumped in compound while statement --> open curly violation

[MichaelChirico]

styler::style_text('
while ({
  bad <- grepl("_", z)
  any(bad)
}) {
  TRUE
}
')
# while (
#   {
#     bad <- grepl("_", z)
#     any(bad)
#   })
# {
#   TRUE
# }

The { is bumped but the style rules dictate { should be on the line with ):

{ should be the last character on the line. Related code (e.g., an if clause, a function declaration, a trailing comma, …) must be on the same line as the opening brace.

AFAIK clauses like ({ ... }) are generally fine, so I'm also not sure why ( and { were separated...

We solved it for functioncalls like tryCatch() and testthat(). If the curly expression is the last, ({ is allowed, with closing }) on same line:

styler::style_text('tryCatch({
  code
})

tryCatch({
  code
  }, 
  x = 2
)')
#> tryCatch({
#>   code
#> })
#> 
#> tryCatch(
#>   {
#>     code
#>   },
#>   x = 2
#> )
