[error] (Compile / compileIncremental) java.lang.ArrayIndexOutOfBoundsException: Index -3 out of bounds for length 228
Unfortunately, I am not ready to minimize the code, and the project is private. So for now, this is mostly posted for statistical purposes. However, if someone wants to look into it, I'm open to helping by providing more information, if it is not too hard to do so.
It's notable that dotty.tools.dotc.printing.SyntaxHighlighting$.highlight(SyntaxHighlighting.scala:128) appears in the stack trace — that suggests this may be a meta-issue where the root cause of the problem is being obscured by an exception that occurs during error handling/reporting. Even without knowing the details of what's causing this, perhaps MessageRendering could react more robustly when something like this goes wrong.
@Bersier thanks for reporting!
Could you please try to compile the same code with --color never and report the error message? As Seth wrote, the error seems to happen when highlighting some code producing an error, so it would be useful to know which code that is.
@mbovel The crash does indeed go away with -color:never. Here is the error message that could not be printed before:
[error] -- Error: /mnt/c/<...>/graph/GraphImpl.scala:46:52
[error] 46 | private[this] case class EdgeImpl(source: Vertex, label: E, target: Vertex) extends Edge
[error] | ^^^^^^^^
[error] |covariant type E occurs in contravariant position in type E of parameter label
I haven't been able to minimize this. I tried:
//> using scala 3.4.0
//> using options -rewrite -indent
sealed trait Vertex {}
sealed trait Edge {}
class Graph[+E] {
private[this] case class EdgeImpl(source: Vertex, label: E, target: Vertex) extends Edge {}
}
class Graph2[+E] {
private[this] case class EdgeImpl(source: Vertex, label: E, target: Vertex) extends Edge {
}
}
But both compile successfully.
@Bersier do you have curly braces on the displayed line in your code?
Also, I noted that the error happens in bracesToIndented, which is only enabled if in.rewriteToIndent is true, which should probably not be the case when highlighting code.
