Nice to see that you got it working! Just a note that intercepting user and standard_error like you do here will be quite fragile as it is not something that we support nor test that it should work. Would you mind describing what it is that you are trying to achieve and maybe we can create an API for it instead?

I wouldn't call it fragile - it worked without problems for 6 years, dialyzer or ssl support breaks on almost every release.

What we do here is intercept standard IO so everything written to stdout and stderr is wrapped in LSP protocol messages, serialized to JSON and printed to stdout in binary. See https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#baseProtocol for details. The reason we do the interception is we don't have control over what build plugins/tools/libs print to std and each message printed that is not LSP breaks the communication channel.

Sure, but we haven't done many changes to the shell and its tools in the last 10+ years. We have however now started to do much more work in that area and the more tools that rely on undocumented and untested behavior, the more things we will accidentally break.

That's what I thought was going on, thanks for confirming. I'll have a think about how we can create an official API for you to use inorder to intercept user output.
