![demo](https://user-images.githubusercontent.com/47070852/155291646-ec1f5623-63ab-4ff5-a48e-cd9670e5c39e.gif)

This extension supports both Vim and Neovim.

## Install

`:CocInstall coc-symbol-line`

## Setup

Add section `%{%get(b:, "coc_symbol_line", "")%}` to tabline/statusline or neovim's winbar.

**NOTE**: `b:coc_symbol_line_plain` does't include clickable sections, maybe you need this if you are using vim.

<summary>lua snippet for neovim</summary>

```lua
function _G.symbol_line()
  local curwin = vim.g.statusline_winid or 0
  local curbuf = vim.api.nvim_win_get_buf(curwin)
  local ok, line = pcall(vim.api.nvim_buf_get_var, curbuf, 'coc_symbol_line')
  return ok and line or ''
end

vim.o.tabline = '%!v:lua.symbol_line()'
vim.o.statusline = '%!v:lua.symbol_line()'
vim.o.winbar = '%!v:lua.symbol_line()'

```

<summary>My config for neovim</summary>

```lua
function _G.symbol_line()
  local bufnr = vim.api.nvim_win_get_buf(vim.g.statusline_winid or 0)
  local ok, line = pcall(vim.api.nvim_buf_get_var, bufnr, 'coc_symbol_line')
  return ok and '%#CocSymbolLine# ' .. line or ''
end

if fn.exists '&winbar' then
  AUTOCMD {
    {
      { 'CursorHold', 'WinEnter', 'BufWinEnter' },
      function()
        if vim.b.coc_symbol_line and vim.bo.buftype == '' then
          if vim.opt_local.winbar:get() == '' then
            vim.opt_local.winbar = '%!v:lua.symbol_line()'
          end
        else
          vim.opt_local.winbar = ''
