🌈 NeoColumn.nvim

📢 Introduction

NeoColumn is a Neovim plugin that shows a focused ColorColumn at a specific position to manage line length. It highlights individual characters, minimizing clutter and enhancing readability

✨ Features

• Display focused ColorColumn/s at the desired position
• Set custom ColorColumn value/s for certain filetypes
• Exclude specific filetypes from the ColorColumn
• Toggle NeoColumn on and off
• Customizable colors

💾 Persistence

NeoColumn maintains the ColorColumn settings for each file, including visibility and position, across sessions.

🛠️ Usage

To toggle NeoColumn on/off, you can use the ToggleNeoColumn command:

:ToggleNeoColumn

You can also create a keybinding to toggle NeoColumn more conveniently:

vim.keymap.set("n", "<leader>h", "<cmd>ToggleNeoColumn<cr>", { noremap = true, silent = true })

To clear the list of enabled/disabled files in NeoColumn, you can use the ClearNeoColumn command:

:ClearNeoColumn
