+# Leaderf-snippet
+
+This plugin takes the advantage of the well-known fuzzy finder [Leaderf](https://github.com/Yggdroot/LeaderF) to provide an intuitive way to input snippets:
+
+![](https://github.com/skywind3000/images/raw/master/p/snippet/snippet1.gif)
+
+Snippet names are hard to remember, therefore, I made a Leaderf extension to help input snippets.
+
+## Feature
+
+- Read snippets from SnipMate or UltiSnips
+- Display snippet descriptions in the fuzzy finder.
+- Work in both INSERT mode and NORMAL mode.
+
+## Installation
+
+```VimL
+" Leaderf-snippet
+Plug 'Yggdroot/LeaderF'
+Plug 'skywind3000/Leaderf-snippet'
+```
+
+A supported snippet engine, [UltiSnips](https://github.com/SirVer/ultisnips) (recommended) or [SnipMate](https://github.com/garbas/vim-snipmate), is required.
+
+
+## Configuration
+
+```VimL
+" maps
+inoremap <c-x><c-x> <c-\><c-o>:Leaderf snippet<cr>
+
+" optional: preview
+let g:Lf_PreviewResult = get(g:, 'Lf_PreviewResult', {})
+let g:Lf_PreviewResult.snippet = 1
+
+```
+
+## Why Leaderf ?
+
+vim-fzf has a `Snippets` command, but it doesn't provide enough information for each snippet and it can't work correctly in INSERT mode:
+
+![](https://github.com/skywind3000/images/raw/master/p/snippet/fzf-snippets.png)
+
+Compare to fzf, Leaderf has a NORMAL mode which allows me to browse my snippets more easily like in a normal vim window:
+
+![](https://github.com/skywind3000/images/raw/master/p/snippet/snippet2.gif)
+
+Browse my snippets with full of details. No worry about forgetting snippets.
+
+## TODO
+
+- [x] snipmate
+- [x] ultisnips
+- [x] snipmate preview
+- [x] ultisnips preview
+- [ ] minisnip 
+
+## Credit
+
+- [Leaderf](https://github.com/Yggdroot/LeaderF): An efficient fuzzy finder that helps to locate files, buffers, mrus, gtags, etc. on the fly.
