staline.nvim

TLDR;
staline(statusline): A simple statusline for neovim written in lua.
stabline(s-tabline): A simple bufferline for neovim written in lua. (sry didnt get a better name.)

Requirements

• Requires neovim version >= 0.7
• vim.opt.laststatus=2 in your init.lua for statusline. (or 3 for global line)
• vim.opt.showtabline=2 in your init.lua for bufferline.
• vim.opt.termguicolors = true must be set.

Installation

use 'tamton-aquib/staline.nvim'

Note Doing this will install both staline and stabline.
But separate setup() is required for each to load up.

To know more about colors and highlights, check highlights wiki

A section (left, right or mid) can take:

• Already defnined section or a simple string:
  • "branch"
  • "a simple string"
• An array of { highlight, string }
  • { "DiagnosticsError", "danger_icon" }
  • { "CustomHighlight", "simple_string" }
• A function for dynamic content

   function()
       return "computed_dynamic_string"
   end

lsp, lsp_name, file_size sections are not included in the default settings.

Showcase

• Evil Line

• Pebble Line

• Simple Line

• Configuration

   require('stabline').setup()

The Default configuration looks something like

require('stabline').setup {
    style       = "bar", -- others: arrow, slant, bubble
    stab_left   = "┃",
    stab_right  = " ",

    -- fg       = Default is fg of "Normal".
    -- bg       = Default is bg of "Normal".
    inactive_bg = "#1e2127",
    inactive_fg = "#aaaaaa",
    -- stab_bg  = Default is darker version of bg.,

    font_active = "bold",
    exclude_fts = { 'NvimTree', 'dashboard', 'lir' },
    stab_start  = "",   -- The starting of stabline
    stab_end    = "",
    numbers = function(bufn, n)
        return '*'..n..' '
    end
}

My personal config as of editing this file

require('stabline').setup {
    style = "slant",
    bg = "#986fec",
    fg = "black",
    stab_right = "",
}

Features

• Lightweight and Fast. staline+stabline took < 1ms. (packers profiling)
• Unicode current mode info. Needs a Nerd Font to be installed.
• Has few builtin sections to chose from.
• Mouse buffer selection on stabline.
• Uses nvim-web-devicons if installed, else uses a default table.

Cons

• No ordering or sorting functions for stabline.
• No lsp info in stabline.
• No git related info on staline except branch name.

TODO

• User configuration options. Needs more work.
• Git info. Only branch info for now, (or ever)
• Adding "opt-in" bufferline function.
• Add config options for bufferline.
• lsp client name in staline.
• buf numbers in stabline.
• transparency problem when changed to 0.7 api.
