Harpoon items + Bottom Centered + General file status

[ChuyB]

Inspired by #31 and #32 for LSP diagnostics and git signs.

The Harpoon line status is influenced by harpoon-lualine and harpoonline. It displays all items and highlights the one selected . On Windows, sometimes Harpoon uses the full file path, causing the status not to recognize the file as active. Renaming the file in Harpoon Quick Menu using the project path fixes the issue. I don't know if this happens on other OS.

I find bottom center placement more readable for me. Works better when theme has no background.

I use it with laststatus = 0 and custom separation lines for horizontal splits.

I really enjoyed making this configuration. It's the most minimal and functional status indicator I've ever had on Neovim!

Configuration:

require("incline").setup({
  window = {
    placement = {
      vertical = "bottom",
      horizontal = "center",
    },
    padding = 0,
    margin = { vertical = 0, horizontal = 0 },
  },
  hide = {
    cursorline = true,
  },
  render = function(props)
    local filename = vim.fn.fnamemodify(vim.api.nvim_buf_get_name(props.buf), ":t")
    if filename == "" then
      filename = "[No Name]"
    end
    local ft_icon, ft_color = devicons.get_icon_color(filename)

    local function get_git_diff()
      local icons = { removed = " ", changed = " ", added = " " }
      local signs = vim.b[props.buf].gitsigns_status_dict
      local labels = {}
      if signs == nil then
        return labels
      end
      for name, icon in pairs(icons) do
        if tonumber(signs[name]) and signs[name] > 0 then
          table.insert(labels, { icon .. signs[name] .. " ", group = "Diff" .. name })
        end
      end
      if #labels > 0 then
        table.insert(labels, { "| " })
      end
      return labels
    end

    local function get_diagnostic_label()
      local icons = { error = " ", warn = " ", info = " ", hint = " " }
      local label = {}

      for severity, icon in pairs(icons) do
        local n = #vim.diagnostic.get(
          props.buf,
          { severity = vim.diagnostic.severity[string.upper(severity)] }
        )
        if n > 0 then
          table.insert(label, { icon .. n .. " ", group = "DiagnosticSign" .. severity })
        end
      end
      if #label > 0 then
        table.insert(label, { "| " })
      end
      return label
    end

    local function get_harpoon_items()
      local harpoon = require("harpoon")
      local marks = harpoon:list().items
      local current_file_path = vim.fn.expand("%:p:.")
      local label = {}

      for id, item in ipairs(marks) do
        if item.value == current_file_path then
          table.insert(label, { id .. " ", guifg = "#FFFFFF", gui = "bold" })
        else
          table.insert(label, { id .. " ", guifg = "#434852" })
        end
      end

      if #label > 0 then
        table.insert(label, 1, { "󰛢 ", guifg = "#61AfEf" })
        table.insert(label, { "| " })
      end
      return label
    end

    local function get_file_name()
      local label = {}
      table.insert(label, { (ft_icon or "") .. " ", guifg = ft_color, guibg = "none" })
      table.insert(label, { vim.bo[props.buf].modified and " " or "", guifg = "#d19a66" })
      table.insert(
        label,
        { filename , gui = vim.bo[props.buf].modified and "bold,italic" or "bold" }
      )
      if not props.focused then
        label["group"] = "BufferInactive"
      end

      return label
    end

    return {
      { "", guifg = "#0e0e0e" },
      {
        { get_diagnostic_label() },
        { get_git_diff() },
        { get_harpoon_items() },
        { get_file_name() },
        guibg = "#0e0e0e",
      },
      { "", guifg = "#0e0e0e" },
    }
  end,
