# sleuth.vim
This plugin automatically adjusts `'shiftwidth'` and `'expandtab'`
heuristically based on the current file, or, in the case the current file is
new, blank, or otherwise insufficient, by looking at other files of the same
type in the current and parent directories. In lieu of adjusting
`'softtabstop'`, `'smarttab'` is enabled.
Compare to [DetectIndent][]. I wrote this because I wanted something fully
automatic. My goal is that by installing this plugin, you can remove all
indenting related configuration from your vimrc.
[DetectIndent]: http://www.vim.org/scripts/script.php?script_id=1171
## Installation
Install using your favorite package manager, or use Vim's built-in package
support:
mkdir -p ~/.vim/pack/tpope/start
cd ~/.vim/pack/tpope/start
git clone https://tpope.io/vim/sleuth.git
vim -u NONE -c "helptags sleuth/doc" -c q
## Notes
* Searching for other files of the same type continues up the directory
hierarchy until a match is found. This means, for example, the indent for
the first file in a brand new Ruby project might very well be derived from
your `.irbrc`. I consider this a feature.
* If your file is consistently indented with hard tabs, `'shiftwidth'` will be
set to your `'tabstop'`. Otherwise, a `'tabstop'` of 8 is enforced.
* The algorithm is rolled from scratch, fairly simplistic, and only lightly
battle tested. It's probably not (yet) as good as [DetectIndent][].
Let me know what it fails on for you.
