📰 What's new?

This is a full rewrite of the original trouble.nvim.

The new version is much more flexible and powerful, with a lot of new features and improvements:

multiple trouble windows at the same time
LSP document symbols
LSP incoming/outgoing calls
lots of options to configure trouble windows (floats or splits)
focus option to focus the trouble window when opened (or not)
follow option to follow the item under the cursor
pinned option to pin the buffer as the source for the opened trouble window
full tree views of anything
highly configurable views with custom formatters, filters, and sorters
show multiple sections in the same view
multi-line messages
prettier and configurable indent guides
tree view that follows the natural hierarchy of the items (like document symbols, or file structure)
expansive API and Trouble command
trouble modes to define custom views
statusline component (useful with document symbols)

⚡️ Requirements

Neovim >= 0.9.2
Neovim >= 0.10.0 OR the markdown and markdown_inline nvim-treesitter parsers
Properly configured Neovim LSP client
nvim-web-devicons is optional to enable file icons
a theme with properly configured highlight groups for Neovim Diagnostics
a patched font for the default severity and fold icons

📦 Installation

🚀 Usage

Commands

The Trouble command is a wrapper around the Trouble API. It can do anything the regular API can do.

Trouble [mode] [action] [options]

Some examples:

Toggle diagnostics for the current buffer and stay in the current window:
- Trouble diagnostics toggle focus=false filter.buf=0
Show document symbols on the right of the current window. Keep the document symbols in sync with the buffer you started the command in.
- Trouble symbols toggle pinned=true win.relative=win win.position=right
You can use lua code in the options for the Trouble command. The examples below all do the same thing.
- Trouble diagnostics filter.severity=vim.diagnostic.severity.ERROR
- Trouble diagnostics filter.severity = vim.diagnostic.severity.ERROR
- Trouble diagnostics filter = { severity=vim.diagnostic.severity.ERROR }
Merging of nested options, with or without quoting strings:
- Trouble diagnostics win.type = split win.position=right
- Trouble diagnostics win = { type = split, position=right}
- Trouble diagnostics win = { type = "split", position='right'}

Please refer to the API section for more information on the available actions and options.

Modes:

diagnostics: diagnostics
fzf: FzfLua results previously opened with require('trouble.sources.fzf').open().
fzf_files: FzfLua results previously opened with require('trouble.sources.fzf').open().
loclist: Location List

lsp_command: command
lsp_declarations: declarations
lsp_definitions: definitions
lsp_document_symbols: document symbols
lsp_implementations: implementations
lsp_incoming_calls: Incoming Calls
lsp_outgoing_calls: Outgoing Calls

Telescope

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

local actions = require("telescope.actions")
local open_with_trouble = require("trouble.sources.telescope").open

-- Use this to add more results without clearing the trouble list
local add_to_trouble = require("trouble.sources.telescope").add

local telescope = require("telescope")

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

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

fzf-lua

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

local config = require("fzf-lua.config")
local actions = require("trouble.sources.fzf").actions
config.defaults.actions.files["ctrl-t"] = actions.open

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

Statusline Component

Example for lualine.nvim:

{
  "nvim-lualine/lualine.nvim",
  opts = function(_, opts)
    local trouble = require("trouble")
    local symbols = trouble.statusline({
      mode = "lsp_document_symbols",
      groups = {},
      title = false,
      filter = { range = true },
      format = "{kind_icon}{symbol.name:Normal}",
      -- The following line is needed to fix the background color
      -- Set it to the lualine section you want to use
      hl_group = "lualine_c_normal",
    })
    table.insert(opts.sections.lualine_c, {
      symbols.get,
      cond = symbols.has,
    })
  end,
}
