CHANGELOG
=========
0.16.0
------
- *Added `--height HEIGHT[%]` option*
- fzf can now display finder without occupying the full screen
- Preview window will truncate long lines by default. Line wrap can be enabled
by `:wrap` flag in `--preview-window`.
- Latin script letters will be normalized before matching so that it's easier
to match against accented letters. e.g. `sodanco` can match `Só Danço Samba`.
- Normalization can be disabled via `--literal`
- Added `--filepath-word` to make word-wise movements/actions (`alt-b`,
`alt-f`, `alt-bs`, `alt-d`) respect path separators
0.15.9
------
- Fixed rendering glitches introduced in 0.15.8

#### Layout
fzf by default starts in fullscreen mode, but you can make it start below the
cursor with `--height` option.
```sh
vim $(fzf --height 40%)
```
Also check out `--reverse` option if you prefer "top-down" layout instead of
the default "bottom-up" layout.
```sh
vim $(fzf --height 40% --reverse)
```
You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
default.
```sh
export FZF_DEFAULT_OPTS='--height 40% --reverse'
```

It will still work even when you're not on tmux, silently ignoring `-[udlr]`
options, so you can invariably use `fzf-tmux` in your scripts.
Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in
fullscreen mode.

If you're on a tmux session, fzf will start in a split pane. You may disable
this tmux integration by setting `FZF_TMUX` to 0, or change the height of the
pane with `FZF_TMUX_HEIGHT` (e.g. `20`, `50%`).
If you're on a tmux session, you can start fzf in a split pane by setting
`FZF_TMUX` to 1, and change the height of the pane with `FZF_TMUX_HEIGHT`
(e.g. `20`, `50%`).
If you use vi mode on bash, you need to add `set -o vi` *before* `source
