# Dagger
`Dagger` can manage a
[directed acyclic graph](https://github.com/notcalle/tangle) of
[key trees](https://github.com/notcalle/keytree), inspired by the ideas behind [PalletJack](https://github.com/saab-simc-admin/palletjack).
The DAG is stored in a regular posix file system hierarchy, where
_directories_ are vertices with a forest of key trees from the contained
_files_. Edges are formed from the directory structure, and _symlinks_.
Edge direction (default top->down & target->source) is selectable,
but key tree inheritence is always top->down & target->source.
```
spec/fixture/graph
├── vertex1
│ ├── a.yaml # a.b = 2
│ └── c.yaml # c = 3
└── vertex2
├── b.yaml # b = 2
└── parent -> ../vertex1 # a.b = 2, c = 3
```
See the [changelog](CHANGELOG.md) for recent changes.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'ruby-dagger'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install ruby-dagger
## Usage
$ bin/console
```ruby
g=Dagger.load('spec/fixture/graph')
=> #
g['/vertex1']['a.b']
=> 2
g['/vertex2']['a.b']
=> 2
g['/vertex2'].local['a.b']
=> nil
```
## Development
