👓 What did you see?

When I review the log file for the LSP, I see

no errors

📦 Which tool/library version are you using?

java version 1.8.0_181

🔬 How could we reproduce it?

open a cucumber file in neovim. The version of cucumber should be 1.2.5

📚 Any additional context?

Hi there,

Thank you for your work; indeed, it's appreciated. Could you please help me? I'm still encountering issues with cucumber-language-server 1.4.0 (and also 1.3.0) installed with Mason on both Mac and Termux.

:MasonInstall cucumber-language-server@1.4.0

If I install version 1.2.0, I encounter issue #72.

Do you have any hacks or suggestions to resolve this, please?

Thank you.

Hi @restagner and @johnbunky,

The latest version is experiencing a startup problem when used outside of VS Code. I've just released a temporary package, @binhtran432k/cucumber-language-server, based on the latest update from Git that includes the startup fix from #74.

Could you please test it? Use npm install -g @binhtran432k/cucumber-language-server to install it instead of the Mason version. This temporary package will be in place until #74 is merged and a new version is released by @cucumber.

However, it is not working properly in all of the newest Node.js versions. I've tested it and listed the status of the package for each Node.js version here. I hope this information helps both of you.

Node.js version	Status
v16.20.2	Work
v17.9.1	Work
v18.19.0	Work
v19.9.0	Failed
v20.11.0	Failed
v21.5.0	Work

Hi @binhtran432k
Thank you for the update. And it works, but not a perfect Tested with nodejs 18.16.1 and 21.5.0.
On mac I got Lsp logs:
[START][2024-01-15 22:00:41] LSP logging initiated

And on termux I got Lsp logs:
[START][2024-01-15 22:05:25] LSP logging initiated
[WARN][2024-01-15 22:05:25] ...lsp/handlers.lua:137 "The language server cucumber_language_server triggers a registerCapability handler despite dynamicRegistration set to false. Report upstream, this warning is harmless"

[ERROR][2024-01-15 22:05:26] ...lsp/handlers.lua:535 "Failed to reindex: undefined is not iterable (cannot read property Sym bol(Symbol.iterator))"

In any case it better than nothing, thank you a lot for your job.

Regards.

I'm trying to integrate this language to Emacs' lsp-mode, but experiencing the same issue. 🤔
