### Conditional activation
Use plain "if" statement to conditionally activate plugins:
```vim
if has('mac')
Plug 'junegunn/vim-xmark'
endif
```
The caveat is that when the condition is not met, `PlugClean` will try to remove the plugin. This can be problematic if you share the same configuration across terminal Vim, GVim, and Neovim.
```vim
" When started with plain Vim, the plugin is not registered
" and PlugClean will try to remove it
if has('nvim')
Plug 'benekastah/neomake'
endif
```
Alternatively, you can pass an empty `on` or `for` option so that the plugin is registered but not loaded by default depending on the condition.
```vim
Plug 'benekastah/neomake', has('nvim') ? {} : { 'on': [] }
```
A helper function can improve the readability.
```vim
function! Cond(cond, ...)
let opts = get(a:000, 0, {})
return a:cond ? opts : extend(opts, { 'on': [] })
endfunction
" Looks better
Plug 'benekastah/neomake', Cond(has('nvim'))
" With other options
Plug 'benekastah/neomake', Cond(has('nvim'), { 'on': 'Neomake' })
```
### Gist as plugin
vim-plug does not natively support installing small Vim plugins from Gist.
But there is a workaround if you really want it.
```vim
Plug 'https://gist.github.com/952560a43601cd9898f1.git',
\ { 'as': 'xxx', 'do': 'mkdir -p plugin; cp -f *.vim plugin/' }
```
### Migrating from other plugin managers

### Loading plugins manually
With `on` and `for` options, vim-plug allows you to defer loading of plugins. But if you want a plugin to be loaded on an event that is not supported by vim-plug, you can set `on` or `for` option to an empty list, and use `plug#load(names...)` function later to load the plugin manually. The following example will load [ultisnips](https://github.com/SirVer/ultisnips) and [YouCompleteMe](https://github.com/Valloric/YouCompleteMe) first time you enter insert mode.
