Josh Rosen created SPARK-3854:
---------------------------------
Summary: Scala style: require spaces before `{`
Key: SPARK-3854
URL: https://issues.apache.org/jira/browse/SPARK-3854
Project: Spark
Issue Type: Sub-task
Reporter: Josh Rosen
We should require spaces before opening curly braces. This isn't in the style
guide, but it probably should be:
{code}
// Correct:
if (true) {
println("Wow!")
}
// Incorrect:
if (true){
println("Wow!")
}
{code}
See https://github.com/apache/spark/pull/1658#discussion-diff-18611791 for an
example "in the wild."
{{git grep "){"}} shows only a few occurrences of this style.
