# gitattributes
[](http://travis-ci.org/realityforge/gitattributes)
Classes to parse `.gitattributes` files.
A simple example of it's usage:
### Read an existing .gitattributes
Read an existing file that looks like
```
README.md text eol=lf
*.jpg binary
```
With code that looks like
```ruby
require 'reality/gitattributes'
attributes = Reality::Git::Attributes.parse('/home/user/myrepo')
attributes.attributes('README.md') # => { "text" => true, "eol" => "lf }
attributes.attributes('*.jpg') # => { "binary" => true }
```
### Write .gitattributes
```ruby
require 'reality/gitattributes'
attributes = Reality::Git::Attributes.new('/home/user/myrepo')
attributes.dos_text_rule('*.cmd')
attributes.dos_text_rule('*.rdl', :eofnl => false)
attributes.unix_text_rule('*.sh')
attributes.text_rule('*.md')
attributes.binary_rule('*.jpg')
attributes.write_to('/home/user/myrepo/.gitattributes')
```
produces a file that looks like
```
*.cmd text eol=crlf
*.rdl text eol=crlf -eofnl
*.sh text eol=lf
*.md text
*.jpg binary
```
You could also pass `:prefix` and `:normalize` options to write_to method like
```ruby
attributes.write_to('/home/user/myrepo/.gitattributes', :normalize => true, :prefix => '# DO NOT EDIT: File is auto-generated')
```
to produce a file that looks like:
```
# DO NOT EDIT: File is auto-generated
*.cmd text eol=crlf
*.md text
*.rdl text eol=crlf -eofnl
*.sh text eol=lf
```
