+# vim-fugistate
+
+## Usage
+This simple plugin provides a function which returns the name of current file with git status if available using
+[vim-fugitive](https://github.com/tpope/vim-fugitive) and is intended for statusline integration.
+
+```vim
+:echo FugiState()
+```
+
+It will show something like `main.c [ M]` for modified file `main.c`.
+
+For example, to show the filename with git status using [lightline.vim](https://github.com/itchyny/lightline.vim),
+configure as follows.
+
+```vim
+let g:lightline = {
+      \ 'active': {
+      \   'left': [ [ 'mode', 'paste' ],
+      \             [ 'readonly', 'filenamestatus', 'modified' ] ]
+      \ },
+      \ 'component_function': {
+      \   'filenamestatus': 'FugiState'
+      \ },
+      \ }
+```
+
+### Filename configuration
+
+The plugin provides `g:fugistate_expand_filename` to modify the value the filename should be expanded to.
+Default value is set to `'%:t'` and will show filename without path. Use available values like `'%:p'` for full path
+or `''` to use `@%` for directory/filename relative to current working directory.
