| Autocommands are commands that are automatically executed when some event occurs.Some examples of events are: | |
| BufReadPost: After reading a buffer (opening a file) | |
| BufWritePost: After writing a buffer (saving a file) | |
| BufEnter: When entering a buffer | |
| BufLeave: When leaving a buffer | |
| BufNewFile: When creating a new file | |
| Autocommands allow you to automatically execute commands when these events occur. For example: | |
| Set options for certain file types: | |
| autocmd FileType c set shiftwidth=4 softtabstop=4 | |
| Automatically source a file when entering a buffer: | |
| autocmd BufEnter *.{py,c,cpp} source ~/.config/nvim/abbrevs.vim | |
| Automatically save on focus lost: | |
| autocmd FocusLost * :wa | |
| Some other uses of autocommands are: | |
| Syntax highlighting | |
| Indentation | |
| Filetype detection | |
| Autocommands are defined using the :autocmd command. The basic syntax is: | |
| :autocmd {event} {pattern} {command} | |
| {event} is the event that triggers the autocommand (like BufReadPost) | |
| {pattern} is a file pattern that filters which buffers the autocommand applies to | |
| {command} is the command to execute when the event occurs | |
| Autocommands allow you to customize and automate a lot of Vim's behavior. They are a very powerful feature of Vim. |
