==============================================================================
1. Fork status *symbols-outline-fork-status*
|symbols-outline-skip-to-plugin-readme|
This is a fork of the original symbols-outline.nvim which fixes a lot of bugs
from the original repo.
It also adds many more features listed |symbols-outline-below|.
It does not attempt to be an up-to-date successor of the original repo, nor
does it attempt to ensure everyone’s use-cases are satisfied by providing an
overall better experience. It is merely a fork which I maintain for my personal
use-cases which incorporates some selected PRs.
MAINTENANCE STATUS *symbols-outline-fork-status-maintenance-status*
This fork is NOT guaranteed to be completely bug-free, nor as stable as the
original (aside from the already broken things in the original repo). However,
since I use this plugin myself, it is guaranteed that selected issues that I
encounter myself would be fixed (to the best of my ability).
I do not merge PRs from the original repo that I don’t personally need.
- **DO use this fork if**:
- You want to use the bugfixes included in this fork, including `auto_preview`,
and others listed in |symbols-outline-fixes|
- You want to use |symbols-outline-features| available in this fork, which are not
included upstream
- You are OK with some things not being looked after well such as CoC support
(things I don’t personally use)
- **Do NOT use this fork if**:
- You do not need the bugfixes in this fork
- You want a stable plugin (aside from the existing bugs in original repo)
- You don’t need the extra features in this fork
FIXES *symbols-outline-fork-status-fixes*
- Symbol preview empty (simrat39/symbols-outline.nvim#176)
- `SymbolsOutlineClose` crashing when already closed: simrat39/symbols-outline.nvim#163
- Symbols not showing by supporting Nerd fonts v3.0: simrat39/symbols-outline.nvim#225
- Newlines in symbols crash: simrat39/symbols-outline.nvim#204 (simrat39/symbols-outline.nvim#184)
- `code_actions`: simrat39/symbols-outline.nvim#168 (simrat39/symbols-outline.nvim#123)
- Fold all operation too slow: simrat39/symbols-outline.nvim#223 (simrat39/symbols-outline.nvim#224)
- "Invalid buffer id" error simrat39/symbols-outline.nvim#177
- Open handler triggering multiple times ends up in messy state with errors
simrat39/symbols-outline.nvim#235
🛑 BREAKING CHANGES *symbols-outline-fork-status-🛑-breaking-changes*
This section may be relevant to you if your existing config uses the mentioned
features:
- **Config**: `keymaps.focus_location` RENAMED to `keymaps.peek_location` to
avoid confusion with focus window commands.
- **Config**: Marker icons used for guides can now be customized. `show_guides`
REMOVED in favor of `guides.enabled`.
- **Behaviour**: Removed hover floating window from `toggle_preview`.
- Instead, you can set `open_hover_on_preview=true` (true by default) so that
the `hover_symbol` action can be triggered when `toggle_preview`is
triggered.
- The preview window’s size changed to half of neovim height (rather than a
third). This is planned to be configurable.
- The preview window is positioned to be vertically center-aligned (rather
than fixed to the top). This is planned to be configurable.
- **Behaviour**: When `auto_close=true` only auto close if `goto_location` is
used (where focus changed), and not for `focus_location`
(simrat39/symbols-outline.nvim#119).
- **Behaviour**: For `auto_preview=true`, previously preview is only shown after
some delay. Now preview is shown instantly every time the cursor moves.
FEATURES *symbols-outline-fork-status-features*
|symbols-outline-skip-this-section|
Below is a list of features I’ve included in this fork which, at the time of
writing, has not been included upstream (in the original repo). I try my best
to keep this list up to date.
Features/Changes:
- Toggling folds (and added default keymaps for it)
(simrat39/symbols-outline.nvim#194).
- Control focus between outline and code window.
- New commands: SymbolsOutline`Focus,FocusOutline,FocusCode` (see
|symbols-outline-commands|)
- Fixed issues:
- simrat39/symbols-outline.nvim#143
- simrat39/symbols-outline.nvim#174
- simrat39/symbols-outline.nvim#207
- Cursorline option for the outline window.
- Added function and command to show provider and outline window status, somewhat
like `:LspInfo`.
- Move down/up by one line and peek_location immediately.
- Flash highlight when using goto/peek location.

TODO ~
|symbols-outline-skip-this-section|
Key:
>
- [ ] : Planned
- [/] : WIP
- : Idea
<
Items will be moved to above list when complete.
- Folds
- `[ ]` Org-like shift+tab behavior: Open folds level-by-level
- `[ ]` Optionally not opening all child nodes when opening parent node
- Fold siblings and siblings of parent on startup
- Navigation
- Go to parent
- Cycle siblings
- `[ ]` simrat39/symbols-outline.nvim#75: Handling of the outline window when
attached buffer is closed.
Maybe it should continue working, so that pressing enter can open a split to
the correct location, and pressing `q` can properly close the buffer.
- Preview / Hover
- `[/]` Configurable winhighlight options for preview window (like nvim-cmp)
(simrat39/symbols-outline#128)
- `[/]` Configurable width and height of preview window (simrat39/symbols-outline#130)
- `[/]` Outline window customizations (simrat39/symbols-outline#137)

2. symbols-outline.nvim *symbols-outline-symbols-outline.nvim*
**A tree like view for symbols in Neovim using the Language Server Protocol.
Supports all your favourite languages.**
PREREQUISITES *symbols-outline-symbols-outline.nvim-prerequisites*
- `neovim 0.7+`
- Properly configured Neovim LSP client
INSTALLATION *symbols-outline-symbols-outline.nvim-installation*
Use `hedyhli/symbols-outline.nvim` if you wish to use this fork.
Packer:
>lua
use 'simrat39/symbols-outline.nvim'
<
Lazy:
>lua
{
"simrat39/symbols-outline.nvim",
config = function()
-- Example mapping to toggle outline
vim.keymap.set("n", "<leader>tt", "<cmd>SymbolsOutline<CR>",
{ desc = "SymbolsOutline" })
require("symbols-outline").setup {
-- Your setup opts here (leave empty to use defaults)
}
end,
},
<
Lazy with lazy-loading:
>lua
{
"simrat39/symbols-outline.nvim",
cmd = { "SymbolsOutline", "SymbolsOutlineOpen" },
keys = {
-- Example mapping to toggle outline
{ "<leader>tt", "<cmd>SymbolsOutline<CR>", desc = "Toggle outline window" },
},
opts = {
-- Your setup opts here
},
},
<
This allows Lazy.nvim to lazy load the plugin on commands `SymbolsOutline`,
`SymbolsOutlineOpen`, and your keybindings.
SETUP *symbols-outline-symbols-outline.nvim-setup*
Call the setup function with your configuration options.
Note that a call to `.setup()` is _required_ for this plugin to work
(simrat39/symbols-outline.nvim#213).
>lua
require("symbols-outline").setup({})
<
CONFIGURATION *symbols-outline-symbols-outline.nvim-configuration*
TERMINOLOGY ~
- **Provider**: Source of the items in the outline view. Could be LSP, CoC, etc.
- **Node**: An item in the outline view
- **Fold**: Collapse a collapsible node
- **Location**: Where in the source file a node is from
- **Preview**: Show the location of a node in code using a floating window
- **Peek**: Go to corresponding location in code without leaving outline window
- **Hover**: Cursor currently on the line of a node
- **Hover symbol**: Displaying a floating window to show symbol information
provided by provider.
- **Focus**: Which window the cursor is in
