svlangserver exited with status exit when I call M-x lsp-format-buffer or use C-x h TAB to format the buffer

[erusyd]

Environment: Ubuntu 20.04 LTS amd64, Emacs 27.1

Problem: When I want to format a verilog file in emacs use M-x lsp-format-buffer or use C-x h TAB, the svlangserver exited and remind me to relaunch svlangserver.

svlangserver::stderr information as follow:

events.js:352 throw er; // Unhandled 'error' event ^

Error: write EPIPE at afterWriteDispatched (internal/stream_base_commons.js:156:25) at writeGeneric (internal/stream_base_commons.js:147:3) at Socket._writeGeneric (net.js:787:11) at Socket._write (net.js:799:8) at writeOrBuffer (internal/streams/writable.js:358:12) at Socket.Writable.write (internal/streams/writable.js:303:10) at Socket.Writable.end (internal/streams/writable.js:567:10) at Socket.end (net.js:592:31) at /home/syd/.nvm/versions/node/v14.17.3/lib/node_modules/@imc-trading/svlangserver/lib/svformatter.js:53:34 at new Promise () Emitted 'error' event on Socket instance at: at emitErrorNT (internal/streams/destroy.js:106:8) at emitErrorCloseNT (internal/streams/destroy.js:74:3) at processTicksAndRejections (internal/process/task_queues.js:82:21) { errno: -32, code: 'EPIPE', syscall: 'write' }

Thanks for reporting this. The language server uses verible-verilog-format tool for formatting. Can you confirm if you have the tool installed and in path? You can also provide the path by setting the lsp-clients-svlangserver-formatCommand variable

Thanks for your reply. I changed the path provided by lsp-clients-svlangserver-formatCommand from to It's OK now. I'll close the issue.
