⚙️ Configuration

Setup

Trouble comes with the following defaults:

{
    height = 10, -- height of the trouble list
    icons = true, -- use devicons for filenames
    mode = "lsp_workspace_diagnostics", -- "lsp_workspace_diagnostics", "lsp_document_diagnostics", "quickfix", "lsp_references", "loclist"
    fold_open = "", -- icon used for open folds
    fold_closed = "", -- icon used for closed folds
    action_keys = { -- key mappings for actions in the trouble list
        close = "q", -- close the list
        cancel = "<esc>", -- cancel the preview and get back to your last window / buffer / cursor
        refresh = "r", -- manually refresh
        jump = {"<cr>", "<tab>"}, -- jump to the diagnostic or open / close folds
        jump_close = {"o"}, -- jump to the diagnostic and close the list
        toggle_mode = "m", -- toggle between "workspace" and "document" diagnostics mode
        toggle_preview = "P", -- toggle auto_preview
        hover = "K", -- opens a small poup with the full multiline message
        preview = "p", -- preview the diagnostic location
        close_folds = {"zM", "zm"}, -- close all folds
        open_folds = {"zR", "zr"}, -- open all folds
        toggle_fold = {"zA", "za"}, -- toggle fold of current file
        previous = "k", -- preview item
        next = "j" -- next item
    },
    indent_lines = true, -- add an indent guide below the fold icons
    auto_open = false, -- automatically open the list when you have diagnostics
    auto_close = false, -- automatically close the list when you have no diagnostics
    auto_preview = true, -- automatyically preview the location of the diagnostic. <esc> to close preview and go back to last window
    auto_fold = false, -- automatically fold a file trouble list at creation
    signs = {
        -- icons / text used for a diagnostic
        error = "",
        warning = "",
        hint = "",
        information = "",
        other = "﫠"
    },
    use_lsp_diagnostic_signs = false -- enabling this will use the signs defined in your lsp client
}

💡 if you don't want to use icons or a patched font, you can use the settings below

-- settings without a patched font or icons
{
    fold_open = "v", -- icon used for open folds
    fold_closed = ">", -- icon used for closed folds
    indent_lines = false, -- add an indent guide below the fold icons
    signs = {
        -- icons / text used for a diagnostic
        error = "error",
        warning = "warn",
        hint = "hint",
        information = "info"
    },
    use_lsp_diagnostic_signs = false -- enabling this will use the signs defined in your lsp client
}

🚀 Usage

Commands

Trouble comes with the following commands:

• LspTrouble [provider]: open the list
• LspTroubleClose [provider]: close the list
• LspTroubleToggle [provider]: toggle the list
• LspTroubleRefresh: manually refresh the active list

Example keybindings:

-- Vim Script
nnoremap <leader>xx <cmd>LspTroubleToggle<cr>
nnoremap <leader>xw <cmd>LspTroubleToggle lsp_workspace_diagnostics<cr>
nnoremap <leader>xd <cmd>LspTroubleToggle lsp_document_diagnostics<cr>
nnoremap <leader>xq <cmd>LspTroubleToggle quickfix<cr>
nnoremap <leader>xl <cmd>LspTroubleToggle loclist<cr>
nnoremap gR <cmd>LspTroubleToggle lsp_references<cr>

-- Lua
vim.api.nvim_set_keymap("n", "<leader>xx", "<cmd>LspTroubleToggle<cr>",
  {silent = true, noremap = true}
)
vim.api.nvim_set_keymap("n", "<leader>xw", "<cmd>LspTroubleToggle lsp_workspace_diagnostics<cr>",
  {silent = true, noremap = true}
)
vim.api.nvim_set_keymap("n", "<leader>xd", "<cmd>LspTroubleToggle lsp_document_diagnostics<cr>",
  {silent = true, noremap = true}
)
vim.api.nvim_set_keymap("n", "<leader>xl", "<cmd>LspTroubleToggle loclist<cr>",
  {silent = true, noremap = true}
)
vim.api.nvim_set_keymap("n", "<leader>xq", "<cmd>LspTroubleToggle quickfix<cr>",
  {silent = true, noremap = true}
)
vim.api.nvim_set_keymap("n", "gR", "<cmd>LspTrouble lsp_references<cr>",
  {silent = true, noremap = true}
)

Telescope

You can easily open any search results in Trouble, by defining a custom action:

local actions = require("telescope.actions")
local trouble = require("trouble.providers.telescope")

local telescope = require("telescope")

telescope.setup {
  defaults = {
    mappings = {
      i = { ["<c-t>"] = trouble.open_with_trouble },
      n = { ["<c-t>"] = trouble.open_with_trouble },
    },
  },
}

When you open telescope, you can now hit <c-t> to open the results in Trouble
