+- Added `--pointer` and `--marker` options
+- Added `--keep-right` option that keeps the right end of the line visible
+  when it's too long

 FZF Vim integration
 ===================
 
-This repository only enables basic integration with Vim. If you're looking for
+Installation
-more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
+------------
 
-(Note: To use fzf in GVim, an external terminal emulator is required.)
+Once you have fzf installed, you can enable it inside Vim simply by adding the
+directory to `&runtimepath` in your Vim configuration file. The path may
+differ depending on the package manager.
+
+```vim
+" If installed using Homebrew
+set rtp+=/usr/local/opt/fzf
+
+" If installed using git
+set rtp+=~/.fzf
+```
+
+If you use [vim-plug](https://github.com/junegunn/vim-plug), the same can be
+written as:
+
+```vim
+" If installed using Homebrew
+Plug '/usr/local/opt/fzf'
+
+" If installed using git
+Plug '~/.fzf'
+```
+
+But if you want the latest Vim plugin file from GitHub rather than the one
+included in the package, write:
+
+```vim
+Plug 'junegunn/fzf'
+```
+
+The Vim plugin will pick up fzf binary available on the system. If fzf is not
+found on `$PATH`, it will ask you if it should download the latest binary for
+you.
+
+To make sure that you have the latest version of the binary, set up
+post-update hook like so:
+
+```vim
+Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
+```
+
+Summary
+-------
+
+The Vim plugin of fzf provides two core functions, and `:FZF` command which is
+the basic file selector command built on top of them.
+
+1. **`fzf#run([spec dict])`**
+    - Starts fzf inside Vim with the given spec
+    - `:call fzf#run({'source': 'ls'})`
+2. **`fzf#wrap([spec dict]) -> (dict)`**
+    - Takes a spec for `fzf#run` and returns an extended version of it with
+      additional options for addressing global preferences (`g:fzf_xxx`)
+        - `:echo fzf#wrap({'source': 'ls'})`
+    - We usually *wrap* a spec with `fzf#wrap` before passing it to `fzf#run`
+        - `:call fzf#run(fzf#wrap({'source': 'ls'}))`
+3. **`:FZF [fzf_options string] [path string]`**
+    - Basic fuzzy file selector
+    - A reference implementation for those who don't want to write VimScript
+      to implement custom commands
+    - If you're looking for more such commands, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
+
+The most important of all is `fzf#run`, but it would be easier to understand
+the whole if we start off with `:FZF` command.

+##### Explanation of `g:fzf_colors`
+
+`g:fzf_colors` is a dictionary mapping fzf elements to a color specification
+list:
+
+    element: [ component, group1 [, group2, ...] ]
+
+- `element` is an fzf element to apply a color to:
+
+  | Element               | Description                                           |
+  | ---                   | ---                                                   |
+  | `fg`  / `bg`  / `hl`  | Item (foreground / background / highlight)            |
+  | `fg+` / `bg+` / `hl+` | Current item (foreground / background / highlight)    |
+  | `hl`  / `hl+`         | Highlighted substrings (normal / current)             |
+  | `gutter`              | Background of the gutter on the left                  |
+  | `pointer`             | Pointer to the current line (`>`)                     |
+  | `marker`              | Multi-select marker (`>`)                             |
+  | `border`              | Border around the window (`--border` and `--preview`) |
+  | `header`              | Header (`--header` or `--header-lines`)               |
+  | `info`                | Info line (match counters)                            |
+  | `spinner`             | Streaming input indicator                             |
+  | `prompt`              | Prompt before query (`> `)                            |
+
+- `component` specifies the component (`fg` / `bg`) from which to extract the
+  color when considering each of the following highlight groups
+
+- `group1 [, group2, ...]` is a list of highlight groups that are searched (in
+  order) for a matching color definition
+
+For example, consider the following specification:
+
+```vim
+  'prompt':  ['fg', 'Conditional', 'Comment'],
+```
+
+This means we color the **prompt**
+- using the `fg` attribute of the `Conditional` if it exists,
+- otherwise use the `fg` attribute of the `Comment` highlight group if it exists,
+- otherwise fall back to the default color settings for the **prompt**.
+
+You can examine the color option generated according the setting by printing
+the result of `fzf#wrap()` function like so:
+
+```vim
+:echo fzf#wrap()
+```
+
 `fzf#run`
 ---------
 
-For more advanced uses, you can use `fzf#run([options])` function.

 `fzf#wrap`
 ----------
 
-`:FZF` command provided by default knows how to handle `CTRL-T`, `CTRL-X`, and
+We have seen that several aspects of `:FZF` command can be configured with
-`CTRL-V` and opens the selected file in a new tab, in a horizontal split, or
+a set of global option variables; different ways to open files
-in a vertical split respectively. And these key bindings can be configured via
+(`g:fzf_action`), window position and size (`g:fzf_layout`), color palette
-`g:fzf_action`. This is implemented using `--expect` option of fzf and the
+(`g:fzf_colors`), etc.
-smart sink function. It also understands `g:fzf_colors`, `g:fzf_layout` and
-`g:fzf_history_dir`. However, `fzf#run` doesn't know about any of these
-options.
 
-By *"wrapping"* your options dictionary with `fzf#wrap` before passing it to
+So how can we make our custom `fzf#run` calls also respect those variables?
-`fzf#run`, you can make your command also support the options.
+Simply by *"wrapping"* the spec dictionary with `fzf#wrap` before passing it
+to `fzf#run`.
+
+- **`fzf#wrap([name string], [spec dict], [fullscreen bool]) -> (dict)`**
+    - All arguments are optional. Usually we only need to pass a spec dictionary.
+    - `name` is for managing history files. It is ignored if
+      `g:fzf_history_dir` is not defined.
+    - `fullscreen` can be either `0` or `1` (default: 0).
+
+`fzf#wrap` takes a spec and returns an extended version of it (also
+a dictionary) with additional options for addressing global preferences. You
+can examine the return value of it like so:
 
 ```vim
-" Usage:
+echo fzf#wrap({'source': 'ls'})
-"   fzf#wrap([name string,] [opts dict,] [fullscreen boolean])
-
-" This command now supports CTRL-T, CTRL-V, and CTRL-X key bindings
-" and opens fzf according to g:fzf_layout setting.
-command! Buffers call fzf#run(fzf#wrap(
-    \ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}))
-
-" This extends the above example to open fzf in fullscreen
-" when the command is run with ! suffix (Buffers!)
-command! -bang Buffers call fzf#run(fzf#wrap(
-    \ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0))
-
-" You can optionally pass the name of the command as the first argument to
-" fzf#wrap to make it work with g:fzf_history_dir
-command! -bang Buffers call fzf#run(fzf#wrap('buffers',
-    \ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0))
 ```
 
-fzf inside terminal buffer
+After we *"wrap"* our spec, we pass it to `fzf#run`.
---------------------------
+
+```vim
+call fzf#run(fzf#wrap({'source': 'ls'}))
+```
+
+Now it supports `CTRL-T`, `CTRL-V`, and `CTRL-X` key bindings and it opens fzf
+window according to `g:fzf_layout` setting.
+
+To make it easier to use, let's define `LS` command.
+
+```vim
+command! LS call fzf#run(fzf#wrap({'source': 'ls'}))
+```
+
+Type `:LS` and see how it works.
+
+We would like to make `:LS!` (bang version) open fzf in fullscreen, just like
+`:FZF!`. Add `-bang` to command definition, and use `<bang>` value to set
+the last `fullscreen` argument of `fzf#wrap` (see `:help <bang>`).
+
+```vim
+" On :LS!, <bang> evaluates to '!', and '!0' becomes 1
+command! -bang LS call fzf#run(fzf#wrap({'source': 'ls'}, <bang>0))
+```
+
+Our `:LS` command will be much more useful if we can pass a directory argument
+to it, so that something like `:LS /tmp` is possible.
+
+```vim
+command! -bang -complete=dir -nargs=* LS
+    \ call fzf#run(fzf#wrap({'source': 'ls', 'dir': <q-args>}, <bang>0))
+```
+
+Lastly, if you have enabled `g:fzf_history_dir`, you might want to assign
+a unique name to our command and pass it as the first argument to `fzf#wrap`.
+
+```vim
+" The query history for this command will be stored as 'ls' inside g:fzf_history_dir.
+" The name is ignored if g:fzf_history_dir is not defined.
+command! -bang -complete=dir -nargs=* LS
+    \ call fzf#run(fzf#wrap('ls', {'source': 'ls', 'dir': <q-args>}, <bang>0))
+```
+
+Tips
+----
+
+### fzf inside terminal buffer
 
 The latest versions of Vim and Neovim include builtin terminal emulator
 (`:terminal`) and fzf will start in a terminal buffer in the following cases:
 
 - On Neovim
 - On GVim
-- On Terminal Vim with the non-default layout
+- On Terminal Vim with a non-default layout
     - `call fzf#run({'left': '30%'})` or `let g:fzf_layout = {'left': '30%'}`
 
-### Hide statusline
+#### Starting fzf in a popup window
-
-When fzf starts in a terminal buffer, you may want to hide the statusline of
-the containing buffer.
 
 ```vim
-autocmd! FileType fzf
+" Required:
-autocmd  FileType fzf set laststatus=0 noshowmode noruler
+" - width [float range [0 ~ 1]]
-  \| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
+" - height [float range [0 ~ 1]]
+"
+" Optional:
+" - xoffset [float default 0.5 range [0 ~ 1]]
+" - yoffset [float default 0.5 range [0 ~ 1]]
+" - highlight [string default 'Comment']: Highlight group for border
+" - border [string default 'rounded']: Border style
+"   - 'rounded' / 'sharp' / 'horizontal' / 'vertical' / 'top' / 'bottom' / 'left' / 'right'
+let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
+```
+
+#### Hide statusline
+
+When fzf starts in a terminal buffer, the file type of the buffer is set to
+`fzf`. So you can set up `FileType fzf` autocmd to customize the settings of
+the window.
+
+For example, if you use the default layout (`{'down': '~40%'}`) on Neovim, you
+might want to temporarily disable the statusline for a cleaner look.
+
+```vim
+if has('nvim') && !exists('g:fzf_layout')
+  autocmd! FileType fzf
+  autocmd  FileType fzf set laststatus=0 noshowmode noruler
+    \| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
+endif

 FZF VIM INTEGRATION                                        *fzf-vim-integration*

-more, check out {fzf.vim}{1} project.
 
-(Note: To use fzf in GVim, an external terminal emulator is required.)

+==============================================================================
+
+The Vim plugin of fzf provides two core functions, and `:FZF` command which is
+the basic file selector command built on top of them.
+
+ 1. `fzf#run([spec dict])`
+   - Starts fzf inside Vim with the given spec
+   - `:call fzf#run({'source': 'ls'})`
+ 2. `fzf#wrap([spec dict]) -> (dict)`
+   - Takes a spec for `fzf#run` and returns an extended version of it with
+     additional options for addressing global preferences (`g:fzf_xxx`)
+     - `:echo fzf#wrap({'source': 'ls'})`
+   - We usually wrap a spec with `fzf#wrap` before passing it to `fzf#run`
+     - `:call fzf#run(fzf#wrap({'source': 'ls'}))`
+ 3. `:FZF [fzf_options string] [path string]`
+   - Basic fuzzy file selector
+   - A reference implementation for those who don't want to write VimScript to
+     implement custom commands
+   - If you're looking for more such commands, check out {fzf.vim}{1} project.
+
+The most important of all is `fzf#run`, but it would be easier to understand
+the whole if we start off with `:FZF` command.

 ==============================================================================
 
-`:FZF` command provided by default knows how to handle CTRL-T, CTRL-X, and
+                                                                      *fzf#wrap*
-CTRL-V and opens the selected file in a new tab, in a horizontal split, or in
-a vertical split respectively. And these key bindings can be configured via
-`g:fzf_action`. This is implemented using `--expect` option of fzf and the
-smart sink function. It also understands `g:fzf_colors`, `g:fzf_layout` and
-`g:fzf_history_dir`. However, `fzf#run` doesn't know about any of these
-options.
 
-By "wrapping" your options dictionary with `fzf#wrap` before passing it to
+We have seen that several aspects of `:FZF` command can be configured with a
-`fzf#run`, you can make your command also support the options.
+set of global option variables; different ways to open files (`g:fzf_action`),
+window position and size (`g:fzf_layout`), color palette (`g:fzf_colors`),
+etc.
+
+So how can we make our custom `fzf#run` calls also respect those variables?
+Simply by "wrapping" the spec dictionary with `fzf#wrap` before passing it to
+`fzf#run`.
+
+ - `fzf#wrap([name string], [spec dict], [fullscreen bool]) -> (dict)`
+   - All arguments are optional. Usually we only need to pass a spec
+     dictionary.
+   - `name` is for managing history files. It is ignored if `g:fzf_history_dir`
+     is not defined.
+   - `fullscreen` can be either `0` or `1` (default: 0).
+
+`fzf#wrap` takes a spec and returns an extended version of it (also a
+dictionary) with additional options for addressing global preferences. You can
+examine the return value of it like so:
 >
-    " Usage:
+    echo fzf#wrap({'source': 'ls'})
-    "   fzf#wrap([name string,] [opts dict,] [fullscreen boolean])
+<
+After we "wrap" our spec, we pass it to `fzf#run`.
+>
+    call fzf#run(fzf#wrap({'source': 'ls'}))
+<
+Now it supports CTRL-T, CTRL-V, and CTRL-X key bindings and it opens fzf
+window according to `g:fzf_layout` setting.
 
-    " This command now supports CTRL-T, CTRL-V, and CTRL-X key bindings
+To make it easier to use, let's define `LS` command.
-    " and opens fzf according to g:fzf_layout setting.

+    command! LS call fzf#run(fzf#wrap({'source': 'ls'}))
-        \ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}))
+<
+Type `:LS` and see how it works.
 
-    " This extends the above example to open fzf in fullscreen
+We would like to make `:LS!` (bang version) open fzf in fullscreen, just like

-
