smartcolumn.nvim

📃 Introduction

A Neovim plugin hiding your colorcolumn when unneeded.

⚙️ Features

The colorcolumn is hidden as default, but it appears after one of lines in the scope exceeds the colorcolumn value you set.

You can:

• hide colorcolumn for specific filetype
• set custom colorcolumn value for different filetype
• specify the scope where the plugin should work

📦 Installation

1. Install via your favorite package manager.

• lazy.nvim

{
  "m4xshen/smartcolumn.nvim",
  opts = {}
},

• packer.nvim

use "m4xshen/smartcolumn.nvim"

• vim-plug

Plug "m4xshen/smartcolumn.nvim"

2. Setup the plugin in your init.lua. This step is not needed with lazy.nvim if opts is set as above.

require("smartcolumn").setup()

🔧 Configuration

You can pass your config table into the setup() function or opts if you use lazy.nvim.

The available options:

• colorcolumn (strings or table) : screen columns that are highlighted
  • "80" (default)
  • { "80", "100" }
• disabled_filetypes (table of strings) : the colorcolumn will be disabled under the filetypes in this table
  • { "help", "text", "markdown" } (default)
  • { "NvimTree", "lazy", "mason", "help", "checkhealth", "lspinfo", "noice", "Trouble", "fish", "zsh"}

[!NOTE] You can use :set filetype? to check the filetype of current buffer.

• scope (strings): the plugin only checks whether the lines within scope exceed colorcolumn
  • "file" (default): current file
  • "window": visible part of current window
  • "line": current line
• custom_colorcolumn (table or function returning string): custom colorcolumn values for different filetypes
  • {} (default)
  • { ruby = "120", java = { "180", "200"} }
  • you can also pass a function to handle more complicated logic:

  custom_colorcolumn = function ()
     return "100"
  end
  

Default config

local config = {
   colorcolumn = "80",
   disabled_filetypes = { "help", "text", "markdown" },
   custom_colorcolumn = {},
   scope = "file",
}
