Thanks for the bug report, that file with that commit seems to work fine for me, do you see anything in the "Lean: Editor" Output page?
If you turn on the Lean Server logging via this setting you could attach the wdIn.txt, wdOut.txt and fwIn.txt and fwOut.txt log files. I like to also put these logs in a separate "log" folder using the second setting here:
I tried to reproduce again on this file and I can't, it all seems to be working now. I'll keep developing and see if I can catch it failing again.
At the time, Lean Editor: Output was only emitting keepAlive messages. I think the server was dead or in a weird state.
I haven't quite figured out the MWE yet. Possibly a vscode-lean4 bug.
There seem to be certain files for me where vscode and Lean will stop talking to each other. I have observed this a few times but today I found an example on the main branch of mathlib.
Please let me know, firstly, whether you can reproduce this because I am not sure whether my setup has entered a bad state.
Reproduction
The one that doesn't work for me is the file showTerm.lean from leanprover-community/mathlib4 (commit 492d30e023d3275404876f2c2ac8b68744a98b1f) with vscode extension version v0.0.95. Lean version is
Lean (version 4.0.0-nightly-2022-09-22, commit 708a777d7472, Release)
. I double checked that vscode was using the right lean version.Opening this file will cause the server to not respond.![image](https://user-images.githubusercontent.com/5064353/191949003-64ae9071-2eee-4a51-9ccd-d1357f7c36e2.png)
If instead I switch to this page from a file that is working normally I get an error in the infoview
I tracked down this error being due to the rpc call
'Lean.Widget.getInteractiveDiagnostics'
resolving toundefined
, however this line assumes that it is an array, causing the error.However I can't determine why the connection is entering a weird state for this file, no other server calls are functioning at all. If I open the file with
"lean4.trace.server": "verbose",
, there is no traffic to or from the server other thankeepAlive
