neo-tree-diagnostics

An extension for neo-tree.nvim implementing a source for viewing workspace diagnostics.

Installation

Installing this plugin should be possible using your package manager of choice, assuming neo-tree.nvim has been installed. The following uses packer.nvim:

use {
  "mrbjarksen/neo-tree-diagnostics.nvim",
  requires = "nvim-neo-tree/neo-tree.nvim",
  module = "neo-tree.sources.diagnostics", -- if wanting to lazyload
}

Configuration

Configuration is done within the neo-tree config:

require("neo-tree").setup({
  sources = {
    "filesystem",
    "buffers",
    "git_status",
    "diagnostics",
    -- ...and any additional source
  },
  -- These are the defaults
  diagnostics = {
    auto_preview = { -- May also be set to `true` or `false`
      enabled = false, -- Whether to automatically enable preview mode
      preview_config = {}, -- Config table to pass to auto preview (for example `{ use_float = true }`)
      event = "neo_tree_buffer_enter", -- The event to enable auto preview upon (for example `"neo_tree_window_after_open"`)
    },
    bind_to_cwd = true,
    diag_sort_function = "severity", -- "severity" means diagnostic items are sorted by severity in addition to their positions.
                                     -- "position" means diagnostic items are sorted strictly by their positions.
                                     -- May also be a function.
    follow_current_file = { -- May also be set to `true` or `false`
      enabled = true, -- This will find and focus the file in the active buffer every time
      always_focus_file = false, -- Focus the followed file, even when focus is currently on a diagnostic item belonging to that file
      expand_followed = true, -- Ensure the node of the followed file is expanded
      leave_dirs_open = false, -- `false` closes auto expanded dirs, such as with `:Neotree reveal`
      leave_files_open = false, -- `false` closes auto expanded files, such as with `:Neotree reveal`
    },
    group_dirs_and_files = true, -- when true, empty folders and files will be grouped together
    group_empty_dirs = true, -- when true, empty directories will be grouped together
    show_unloaded = true, -- show diagnostics from unloaded buffers
    refresh = {
      delay = 100, -- Time (in ms) to wait before updating diagnostics. Might resolve some issues with Neovim hanging.
      event = "vim_diagnostic_changed", -- Event to use for updating diagnostics (for example `"neo_tree_buffer_enter"`)
                                        -- Set to `false` or `"none"` to disable automatic refreshing
      max_items = 10000, -- The maximum number of diagnostic items to attempt processing
                         -- Set to `false` for no maximum
    },
  },
})
