Disable signatureHelp Popup

[879hun675tgfoO098]

Hello,

I'm very sorry to have to write to this forum, but I've tried everything, I'm at my wits end and I need help. I've scowered the documentation, tried every modification possible, even paid a subscription to ChatGPT, to no avail ... and the problem does seem incredibly trivial but I'm about to call it quits and go back to VSCode, so this is true desperation.

How, for the life of every deity since the creation of the universe, do you disable signatureHelp in the Astrovim LSP (I usually dable in rust, but the problem is also valid for other languages) ? You see, everytime I drop into "insert" mode within a function / symbol in my code, the LSP shows a huge and perfectly over the top floating window that details the signature, and it actually sits above my code so that I cannot see what I'm doing anymore. Apparently that's a default that people like ... not me. It hides everything under it, and obfuscate the context. It's very distracting and clumsy.

I've attached an image so that you can see what I'm talking about.

If you know how to disable this, you're my hero.

Now, I've been suffering from this for "years", seriously, and I've tried all the obvious stuff that LLMs spit out.

I need a solution, like, a real solution, to fix the problem.

Cheers !

Hi, I got the same issue, have you found any solution now?

Hi, bro. I found the real solution now(after hours effert)!

What you need to do is just disable this option to you lspconfig:

rust_analyzer = {
  settings = {
    ["rust-analyzer"] = {
      signatureInfo = {
        -- detail = "parameters", -- only show parameters
        documentation = { enable = false }, -- disable signature detail
      },
    },
  },
},

I works well for me. I hope I can be your hero :)

Hey ! Well thank you very much, you are my hero ! I think it’s working … I say think because I still have things popping up everywhere, but the documentation IS gone, and that’s great. Thank you. I never understood the neovim configuration files, never. Been using neovim for years, literally, but it just leaves me cold, I don’t want to delve into it, I hate the concept, the LUA language, the half-assed solutions that are so brittle you dare not touch your keyboard anymore. The whole thing rocks beyond belief for the most part, but the configuration man … my god. No. Hell. Thank you again for your efforts in this. Cheers, Yvick

No worries.
And Yeah I totally agree. Configuring Neovim plugins is such a hassle.
Most config options are super obscure with barely any proper documentation. On top of that, plugins conflict with each other all the time alongside frequent version breaking changes. It’s really hard to figure out the correct setup most of the time and you basically have to guess half the way.

It’s literally a bottomless pit. Definitely not worth sinking too much time into it. I end up tweaking Neovim all day without writing a single line of actual code.

Still, it feels super satisfying once you finally get it perfectly tailored exactly how you want it haha :)
