The MVar is an implementation detail, better hide it behind a callback, or a hook to run an Lsp action on initialisation.
And please move it to the Arguments record, to keep the API simple and minimise the breakage

I wasn't sure about whether to put it in Arguments, in some places there seems to be an assumption that it reflects CLI arguments. But yeah, it seems better in there.

I ended up putting it in the Arguments record for ghcide but not HLS: the HLS Arguments are very tightly coupled to argument parsing, expect to be Show-able etc, so it really didn't fit.

I meant the Arguments datatype passed to defaultMain, that is Development.IDE.Main.Arguments.
Sorry I wasn't more specific.

Please keep in mind what happens with the command line interface, where there is no LSP environment. |
That should be fine, although it does suggest to me that we should use a bounded queue for the backlog: otherwise it will just accumulate logs forever because it can never send them. |

Okay, this is now a much more modest refactoring that still uses the plugin technique to install the handler, and adds logging via Also I officially give @pepeiborra 1 I-told-you-so point ;) |
* Refactor LSP logger and log via `window/logMessage` * Skip logging notifications in tests Co-authored-by: Pepe Iborra <pepeiborra@gmail.com>
Also adds a logger that forwards on messages via
window/logMessage.
