Autoload Scripts

:help 'runtimepath'

~/.config/nvim
├── autoload
│   └── load.vim
├── ftplugin
│   └── ftypeAAA.vim
├── init.vim
├── plugin
│   └── autoload_test.vim
└── test

• plugin/

  • The scripts are loaded when nvim start.

• autoload/

  • The scripts are loaded only when its command is called.

  For example, the autoload/load.vim will be loaded after plugin/autoload_test.vim is executed.

  " plugin/autoload_test.vim
  call load#Hello()

  " autoload/load.vim
  function! load#Hello()
  echo "hello!"
  endfunction

  Note: It seems that we should use namespace to invoke the script under autoload .

• ftplugin/

  • When a file is opened, script corresponded to the file type will be load

  For example, I edit a file called foo.txt. With :set ft? we can find it's a text type file. Then :set ft=ftypeAAA, it's ftypeAAA type now, and you can find nvim load ftypeAAA.vim immediately.

• Reference

  • Please explain Vim's configuration directories hierarchy
  • Using Vim packages

Script

• Declare a function

" '!' is used to overwrite the func previously defined
function!  hello() 

echo "hello!"

endfunction

• Reference
  • usr_41.txt - 适用于 Vim 8.2 版本

Problems

• Why Ctrl-V not enter visual mode?
  • Check if you are in Window ternimal first. The default setting of wt will map C-V to C-shift-V.
  • ref1, ref2
