How do I reload my vimrc or source a Vimscript file?

Explanation

The :source command reads and executes a Vimscript file. Using % as the argument sources the current file, making it easy to reload your vimrc.

How it works

• :source ~/.vimrc re-reads your vimrc
• :source % sources the current file (useful when editing vimrc)
• All commands in the file are executed sequentially

Example

While editing your vimrc:

:source %    " Apply changes immediately

Or from anywhere:

:source ~/.vimrc    " Reload configuration

Tips

• :so is the abbreviation for :source
• Be careful with duplicate autocommands — use augroup with autocmd!
• Some settings do not take effect until Vim restarts
• :runtime is similar but searches the runtime path
• Neovim uses ~/.config/nvim/init.vim or init.lua
