Cabi

A simple, flat-file datastore for Ruby.

Getting Started

Cabi is a flat-file datastore where data is stored by directory stucture and accessed by colon-delimited strings. Here's how to get started:

$ gem install cabi
$ cabi init --mock    # use --mock to init cabi data with some fake data

Then access your data like so:

$ irb
  > require 'cabi'
  > Cabi.read('pages:about:body')
    => "<h1>Hello, Cabi!</h1>"

Usage

Assuming your cabi-data folder has the following structure:

.
├── info.yml
├── nav.yml
├── pages
│   └── about
│       ├── body.html
│       ├── meta.yml
│       ├── person-1.html
│       ├── person-2.html
│       └── person-3.html
└── posts
    └── random-article
        ├── index.html
        └── nav.html

You could then query your data like so:

# Simple selection
Cabi.read('pages:about:body')                 # contents of page/about/body.html

# Selection with/without explicit file extension
Cabi.read('posts:some-article:index')         # contents of posts/some-article/index.html
Cabi.read('posts:some-article:index.html')    # contents of posts/some-article/index.html

# Bulk selection - since Cabi uses dir globbing 
# under the hood, any valid dir glob in your 
# selection will work.
Cabi.read('pages:about:*')                    # an array of body.html and meta.yml contents
Cabi.read('pages:about:person-*')             # an array of all person-* html files
Cabi.read('**/*')                             # an array of all files in data
Cabi.read('**/*').length                      # 9

# Selection within YAML files
Cabi.read('pages:about:meta:foo:bar')         # contents of ['foo']['bar'] in page/about/meta.yml hash
Cabi.read('pages:about:meta.yml:foo:bar')     # same as above
Cabi.read('info:foo:bar:baz')                 # contents of ['foo']['bar']['baz'] in info.yml hash
Cabi.read('info.yml:foo:bar:baz')             # same as above

# Return a file path for a Cabi ID.
Cabi.file('pages:about:meta:foo:bar')         # path fo file at /pages/about/meta/foo/bar
Cabi.path_to_id('/pages/about/meta/foo/bar')  # pages:about:meta:foo:bar

Custom Data Directory

Cabi assumes that your data directory is either a folder at the top level of your project with a .cabi-data file in it (to indicate that it's the data directory). If one is not found, the data directory defaults to ./cabi-data.

For instance, if you had a folder called super-data located inside of your project's root that had a file called .cabi-data inside of it, this folder would be treated as your data directory.
