Custom keymaps being overwritten on setup

[theoribeiro]

I'm having trouble setting up Rust-tools with LunarVim as it is changing some of my keymaps. For instance, by default LunarVim sets up K (shift + k) to call vim.lsp.buf.hover(). After configuring rust-tools, K is calling man for the token under the cursor. Obviously, this generates errors if I press K on a function name, for example:

Is there any way to make sure rust-tools does not configure any keymappings without explicit configuration on my part?

I have the same question

[ZarCastic]

Same here - is there any workaround?

Same! Hope to get this addressed.

I had the same issue. If you are setting up lsp with lspconfig, you might have a function with your lsp related keybindings like so:

local on_attach = function(client, bufnr)
    -- keybind options
    local opts = { noremap = true, silent = true, buffer = bufnr }

    -- set keybinds
    keymap.set("n", "gf", "<cmd>Lspsaga lsp_finder<CR>", opts) -- show definition, references
    keymap.set("n", "gD", "<Cmd>lua vim.lsp.buf.declaration()<CR>", opts) -- got to declaration
    keymap.set("n", "gd", "<cmd>Lspsaga peek_definition<CR>", opts) -- see definition and make edits in window
    keymap.set("n", "gi", "<cmd>lua vim.lsp.buf.implementation()<CR>", opts) -- go to implementation
    keymap.set("n", "<leader>ca", "<cmd>Lspsaga code_action<CR>", opts) -- see available code actions
    keymap.set("n", "<leader>rn", "<cmd>Lspsaga rename<CR>", opts) -- smart rename
    keymap.set("n", "<leader>D", "<cmd>Lspsaga show_line_diagnostics<CR>", opts) -- show  diagnostics for line
    keymap.set("n", "<leader>d", "<cmd>Lspsaga show_cursor_diagnostics<CR>", opts) -- show diagnostics for cursor
    keymap.set("n", "[d", "<cmd>Lspsaga diagnostic_jump_prev<CR>", opts) -- jump to previous diagnostic in buffer
    keymap.set("n", "]d", "<cmd>Lspsaga diagnostic_jump_next<CR>", opts) -- jump to next diagnostic in buffer
    keymap.set("n", "K", "<cmd>Lspsaga hover_doc<CR>", opts) -- show documentation for what is under cursor
    keymap.set("n", "<leader>o", "<cmd>Lspsaga outline<CR>", opts) -- see outline on right hand side

    -- typescript specific keymaps (e.g. rename file and update imports)
    if client.name == "tsserver" then
        keymap.set("n", "<leader>rf", ":TypescriptRenameFile<CR>") -- rename file and update imports
        keymap.set("n", "<leader>oi", ":TypescriptOrganizeImports<CR>") -- organize imports (not in youtube nvim video)
        keymap.set("n", "<leader>ru", ":TypescriptRemoveUnused<CR>") -- remove unused variables (not in youtube nvim video)
    end
end

-- used to enable autocompletion (assign to every lsp server config)
local capabilities = cmp_nvim_lsp.default_capabilities()

You can then pass it to the rust-tools setup function:

rust_tools.setup({
    server = {
        capabilities = capabilities,
        on_attach = on_attach,
    },
})
