How do I configure virtual text?

[mike-lloyd03]

Thanks for this tool. It makes the daily argument with the Rust compiler easier to manage.

The problem I'm running into is that I find all this virtual text to be highly distracting. I would rather errors and hints be hidden until I hover over them or navigate to them with [g. I tried setting various options in tools.inlay_hints but none of them seem to be doing anything (I actually don't know what an inlay hint is.) I've previously just turned off virtual text all together with:

vim.diagnostic.config{
  virtual_text = false
}

But I actually like some of the virtual text that it gives information about the type that each line returns like the gray text shown here:

I don't want to miss out on all of the virtual text features but I'd like to reduce the amount of information overload. How can I configure what information is shown in the virtual text?

[mike-lloyd03]

Additionally, it seems that RustDisableInlayHints only turns off that gray text but the warnings and hints remain appended to the line the appear on. I basically would like the opposite of that. Sorry for my ignorance, but I can't find where any of this is documented. :h doesn't have any results for "inlay"

The yellow/blue stuff is normal neovim diagnostic virtual text, so yeah you can disable it the way you did. For the others, I would probably recommend the only_current_line config option (not sure if that's the exact key, check the readme), this shows the inlay hint only for the currently hovered line

[mike-lloyd03]

I actually tried that and it didn't seem to do anything. I was still getting virtual text on other lines. :(

Could you paste your rust-tools config please?

[mike-lloyd03]

Sure.

local opts = {
    tools = { -- rust-tools options
        autoSetHints = false,
        hover_with_actions = true,
        inlay_hints = {
            -- only_current_line = true,
            show_parameter_hints = false,
            -- parameter_hints_prefix = "",
            -- other_hints_prefix = "",
        },
    },

    -- see https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md#rust_analyzer
    server = {
        settings = {
            -- https://github.com/rust-analyzer/rust-analyzer/blob/master/docs/user/generated_config.adoc
            ["rust-analyzer"] = {
                checkOnSave = {
                    command = "clippy",
                    allFeatures = true,
                },
            }
        }
    },
}

require('rust-tools').setup(opts)

[simrat39]

Sure.

local opts = {
    tools = { -- rust-tools options
        autoSetHints = false,
        hover_with_actions = true,
        inlay_hints = {
            -- only_current_line = true,
            show_parameter_hints = false,
            -- parameter_hints_prefix = "",
            -- other_hints_prefix = "",
        },
    },

                checkOnSave = {
                    command = "clippy",
                    allFeatures = true,
                },
            }
        }
    },
}

require('rust-tools').setup(opts)

only_current_line is commented, is it still broken when its not commented? Might be a bug when show_parameter_hints is disabled and only_current_line is enabled at the same time

[mike-lloyd03]

Okay I uncommented only_current_line and left everything else as is. I'm getting virtual text same as shown in my original post. Toggling show_parameter_hints seems to have no effect.

[mike-lloyd03]

Okay I've created a minimal configuration to try to rule out the problem but it seems to persist. This is my init.lua and virtual text is still showing up in this configuration.

vim.cmd([[
    call plug#begin('~/.local/share/nvim/plugs')

    Plug 'neovim/nvim-lspconfig'
    Plug 'simrat39/rust-tools.nvim'

    call plug#end()
]])

local opts = {
    tools = { -- rust-tools options
        autoSetHints = false,
        hover_with_actions = true,
        inlay_hints = {
            -- only_current_line = true,
            show_parameter_hints = false,
            -- parameter_hints_prefix = "",
            -- other_hints_prefix = "",
        },
    },

            }

    },
