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.

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
