-vim-simple-align is inspired by [h1mesuke/vim-alignta](<https://github.com/h1mesuke/vim-alignta>). It is a simple Vim plugin to align texts.

It is a very great plugin but doesn't work on current Vim. vim-simple-align inherits its philosophy and focuses its limited essential features.

+## Why not vim-easy-align?
 
 Yes, [vim-easy-align](https://github.com/junegunn/vim-easy-align) is a great Vim plugin. However, it is complicated and difficult for me. I can't remember its mappings, options, and syntaxes. It is a so cool product, but not for me.

 Note: dein.vim's lazy loading feature with `on_cmd` option is not recommended for vim-simple-align. You will see `E471: Argument required: ...` if so. To tell the truth, lazy loading of vim-simple-align doesn't make Vim's startup faster. On the one hand, vim-simple-align just defines 1 command when added to `runtimepath`. On the other hand, dein.vim's lazy loading with `on_cmd` also defines a dummy command.

 You can use Vim9 script version if you use Vim 8.2.4053+. Vim9 script version is 5-10 times faster than legacy Vim script version. Vim9 script version is available on [`vim9` branch](https://github.com/kg8m/vim-simple-align/tree/vim9).
