})- use
require('lspsaga.symbolwinbar').get_symbol_nodethis function in your custom winbar to get symbols node and setUser LspsagaUpdateSymbolevent in your autocmds
-- Example:

local file_name = require('lspsaga.symbolwinbar').get_file_name()

vim.api.nvim_create_autocmd('User', {

callback = function() config_winbar_or_statusline() end,
})Support Click in symbols winbar
To enable click support for winbar define a function similar to statusline (Search for "Start of execute function label")
minwid will be replaced with current node. For example:
symbol_in_winbar = {
click_support = function(node, clicks, button, modifiers)
-- To see all avaiable details: vim.pretty_print(node)
local st = node.range.start
local en = node.range['end']
if button == "l" then
if clicks == 2 then
-- double left click to do nothing
else -- jump to node's starting line+char
vim.fn.cursor(st.line + 1, st.character + 1)
end
elseif button == "r" then
if modifiers == "s" then
print "lspsaga" -- shift right click to print "lspsaga"
end -- jump to node's ending line+char
vim.fn.cursor(en.line + 1, en.character + 1)
elseif button == "m" then
-- middle click to visual select node
vim.fn.cursor(st.line + 1, st.character + 1)
vim.cmd "normal v"
vim.fn.cursor(en.line + 1, en.character + 1)
end
end
}- Enable
symbol_in_winbarwill make render outline fast. - Enable
code_action_lightbulbwill make code action fast.
You can use the custom_kind option to change the default icon and color:
-- if only change the color you can do it like
custom_kind = {
Field = '#000000',
}
-- if you want to change the icon and color
custom_kind = {
Field = {'your icon','your color'},
}Colors can be simply changed by overwriting the default highlights groups LspSaga is using.
highlight link LspSagaFinderSelection Search
" or
highlight link LspSagaFinderSelection guifg='#ff0000' guibg='#00ff00' gui='bold'The available highlight groups you can find in here.
lsp finder
peek definition
Code action
Async lightbulb
Hover doc
Rename with preview and select
Jump and show diagnostics
Fastest show symbols in winbar by use cache
Outline
work fast when lspsaga symbol winbar in_custom = true or enable = true,
