How do I make search all parts of items in the snacks.picker?

[Jaehaks]

Hi I'm customizing snacks.picker to go to some heading of markdown file

I made a function Get_Headers() and it returns items list like this.

table.insert(headers, {
  data = {
	level = "H" .. level,
  },
  text = string.gsub(text:sub(level+1), "^%s+", ""),
  file = vim.api.nvim_buf_get_name(cur_bufid),
  pos = {row + 1, col + 1} -- cursor location, it can be used in preview
})

I make custom picker likt this but it can search only itex.text part, but git_log() can do this.

local Show_Headers = function (min_level)
  -- check snacks is loaded
  local snacks_ok, snacks = pcall(require, 'snacks')
  if not snacks_ok then
	vim.notify('snacks.nvim is not installed', vim.log.levels.ERROR)
	return
  end

  snacks.picker.pick({
	finder = function ()
	  local items = Get_Headers(min_level)
	  if items then
		return items
	  end
	  return {}
	end,
	-- format = 'text',
	format = function (item, picker)
	  local a = snacks.picker.util.align -- for setting strict width
	  local ret = {}
	  ret[#ret +1] = {a(item.data.level, 8), 'SnacksPickerGitCommit'}
	  ret[#ret +1] = {" "}
	  ret[#ret +1] = {item.text}
	  snacks.picker.highlight.markdown(ret) -- set highlight for other text
	  return ret
	end,
	preview = 'file',
	confirm = function (picker, item)
	  picker:close()
	  if item then
		vim.api.nvim_win_set_cursor(0, {item.pos[1], item.pos[2]}) -- go to cursor
	  end
	end,

  })
end

for example, I want to search "H1", "H2" , "H3" in the prompt but picker ignore them.

What I missed?

Treat item.text as a search string.

[Jaehaks]

do you mean that i need to input to ret with spliting item.text using sub() function?

[drowning-cat]

Return from get_headers:

item = {
  level = "H1",
  heading = "Rainbow Delimiters",
  text = "H1" .. " " .. "Rainbow Delimiters", -- Search string, no need to display inside formatter
  ...
}

I rewrite like this.

in Get_Header()

local level = tonumber(child_type:sub(6, 6))
local heading = string.gsub(text:sub(level+1), "^%s+", "")

if level <= minlevel then
  table.insert(headers, {
    data = {
      level = "H" .. level,
      heading = heading,
    },
    text = "H" .. level .. " " .. heading, -- it is used for searching only
    file = vim.api.nvim_buf_get_name(cur_bufid),
    pos = {row + 1, col + 1}, -- cursor location, it can be used in preview
  })
end

In Show_Header()

local Show_Headers = function (min_level)
  -- check snacks is loaded
  local snacks_ok, snacks = pcall(require, 'snacks')
  if not snacks_ok then
    vim.notify('snacks.nvim is not installed', vim.log.levels.ERROR)
    return
  end

  snacks.picker.pick({
    finder = function ()
      local items = Get_Headers(min_level)
      if items then
        return items
      end
      return {}
    end,
    format = function (item, picker)
      local a = snacks.picker.util.align -- for setting strict width
      local ret = {}
      ret[#ret +1] = {a(item.data.level, 4), 'SnacksPickerGitCommit'}
      ret[#ret +1] = {item.data.heading}
      snacks.picker.highlight.markdown(ret) -- set highlight for other text
      return ret
    end,
    preview = 'file',
    confirm = function (picker, item)
      picker:close()
      if item then
        vim.api.nvim_win_set_cursor(0, {item.pos[1], item.pos[2]}) -- go to cursor
      end
    end,

  })
end
M.Show_Headers = Show_Headers

And It works. Thanks!
