Description
Describe the request
I spend hours trying to find out why the LSP is not working with Neovim. This was the error message in ~/.local/state/nvim/lsp.log:
INIT --- : error starting clang: running --config-file /home/dean/.arduino15/arduino-cli.yaml compile --fqbn --only-compilation-database --source-override /tmp/2284650797 --build-path /tmp/arduino-language-server3269529476/fullbuild --format json
/home/dean/git/Arduino/SevenSeg: exit status 1
textDocument/didOpen: \27[93mlocked (waiting clangd)
textDocument/didOpen: clangd startup failed: quitting Language server
It misleadingly hinted that clangd was the problem. But actually was the --fqbn parameter empty.
The final solution was to create a sketch.yaml file in the Sketch directory, which contained the FQBN. I found the solution in the nvim-lspconfig repo.
default_fqbn: arduino:avr:unoMy suggestion is to explicitly output "FQBN is missing" which is done when you launch the arduino-cli.
Describe the current behavior
- Neovim v11 with nvim-lspconfig
-
Setup arduino-language-server with Neovim.
-
Setup demo project:
cd /tmp
mkdir test_project
cd test_project
echo "void setup() {} void loop() {}" > test_project.ino
- Open Sketch with Neovim:
nvim test_project.ino
With a configured Neovim setup the language server should try to connect and fail. An error message is shown arduino-language-server failed to start with code 2. If nothing is appearing, check the connection with :LspInfo.
