Make Line Numbers Appear In Documentation

by ADMIN 42 views

Introduction

As a developer, having line numbers in your code editor can be a game-changer. It helps you navigate through your code, identify specific lines, and make debugging a breeze. In this article, we'll explore how to make line numbers appear in your Neovim documentation.

Understanding the Issue

If you're using Neovim and have set number in your init.vim file, you might be wondering why line numbers don't appear in your documentation. You've successfully set number for any buffers you're editing, but when you open your documentation, line numbers are nowhere to be found. This is because the number setting only applies to buffers, not documentation.

The Problem with Buffers and Documentation

In Neovim, buffers and documentation are treated differently. Buffers are the files you're actively editing, while documentation is the help system that provides information about Neovim's features and commands. When you set number in your init.vim file, it only applies to buffers, not documentation.

Solving the Issue

To make line numbers appear in your documentation, you need to set number specifically for the documentation buffer. You can do this by adding the following line to your init.vim file:

autocmd BufReadPre * setlocal number

This will set number for any buffer that's being read, including documentation.

Alternative Solution

If you prefer a more explicit solution, you can use the following command to set number for the documentation buffer:

:autocmd BufReadPre help setlocal number

This will set number specifically for the help buffer, which is used for documentation.

Customizing Line Numbers

Now that you have line numbers appearing in your documentation, you might want to customize their appearance. You can do this by setting the numberwidth option. For example:

set numberwidth=4

This will set the width of the line numbers to 4 characters.
