## 0.8.0

### Enhancements
- Added `spout graphs` command that generates JSON charts and tables of each variable in a dataset
  - This command requires a .spout.yml file to be specified to identify the following variables:
    - `visit`: This variable is used to separate subject encounters in a histogram
    - `charts`: Array of choices, numeric, or integer variables for charts
- The `spout pngs` command now renders the histogram form for each variable
- **Gem Changes**
  - Updated to colorize 0.7.2
- Use of Ruby 2.1.2 is now recommended

## 0.7.0 (April 16, 2014)

### Enhancements
- Added `spout pngs` command that generates pie charts and histograms of each variable in a dataset
  - The following flags are available:
    - `spout p --type-numeric`
    - `spout p --type-integer`
    - `spout p --type-choices`
    - `spout p --size-lg`
    - `spout p --size-sm`
    - `spout p --type-numeric --size-sm`
  - For specific variables the following can be used:
    - `spout p --id-<variable_id>`

## 0.6.0 (March 7, 2014)

### Enhancement
- Added `spout coverage` command that generates a coverage report of how well a dataset matches the data dictionary
  - Generates a viewable report in `<project_name>/coverage/index.html` that shows which columns are covered in CSVs located in `<project_name>/csvs/`
  - Checks that all collected values for a variable with a domain exist in the associated domain
- **Gem Changes**
  - Updated to colorize 0.6.0

## 0.5.0 (February 28, 2014)

### Enhancement
- Tests added to check that variables of type choices have specified a domain
- Tests added to make sure the JSON object `id` matches the variable file name
- Use of Ruby 2.1.1 is now recommended

## 0.4.1 (August 16, 2013)

### Enhancement
- The `spout new <project_name>` command now adds .keep files to the variables and domains folders so they don't need to be recreated in a cloned empty repository

## 0.4.0 (August 7, 2013)

### Enhancements
- Tests for domain existence have changed and now only require the domain name be referenced from the variable instead of the entire domain path
  - To reference a domain from a variable, only the domain name is now required.
  - This change decouples the relative domain folder location from needing to be added among multiple variables which now allows domains to be reorganized without requiring the corresponding variables to be updated to reflect the new path
  - This change is possible since domains need to have a unique name regardless of where they are located

## 0.3.0 (July 11, 2013)

### Enhancements
- Tests now hide passing tests by default
  - To show all tests, use `spout tv`, or `bundle exec rake`
- Tests now include check for variable and domain name uniqueness across folders
  - `include Spout::Tests::VariableNameUniqueness`
  - `include Spout::Tests::DomainNameUniqueness`
- Tests now allow `datetime` as a valid variable type
- Exports will now create a folder based on the version specified in the `VERSION` file located in the root of the data dictionary
  - If a version is specified, `spout export 1.0.1` then the command line version is used
  - If no version is specified, and no `VERSION` file exists, then the default `1.0.0` is used
  - The version must be specified on the first line in the `VERSION` file
- Spout can now create a new Spout project in a folder that was cloned from a Git repository
- Use of Ruby 2.0.0-p247 is now recommended

### Bug Fix
- `DomainExistenceValidation` tests are now case-insensitive

## 0.2.0 (June 26, 2013)

### Enhancements
- Domains can now be imported using `spout import_domains CSVFILE`
- Data Dictionary can now be exported to the Hybrid data dictionary CSV format along with an optional version number:
  - `spout hybrid [1.0.0]`

## 0.1.0 (May 21, 2013)

### Enhancements
- Existing Data Dictionaries can be converted to JSON format from a CSV file
  - Recognized columns:
    - `folder`
    - `id`
    - `display_name`
    - `description`
    - `type`
    - `domain`
    - `units`
    - `calculation`
    - `labels`
  - All other columns will go into an `Other` JSON hash
- Added a rake task to create CSVs of the JSON data dictionary
- Added tests for JSON validity of variables and domains
- Added test to check presence/validity of variable type
- Added test to check if a domain referenced from a variable exists
- Tests can now be added as a group, or on a test-by-test basis
  - Add `require 'spout/tests'` to your individual tests, or to your `test_helper.rb`
  - Include the all or some of the tests provided by Spout
    - `include Spout::Tests` for all tests
    - `include Spout::Tests::JsonValidation` to verify valid JSON formats of domains and variables
    - `include Spout::Tests::VariableTypeValidation` to verify valid variable type for variables
    - `include Spout::Tests::DomainExistenceValidation` to verify existence of domains referenced by variables
- Added `spout new FOLDER` to create an empty data dictionary in the specified `FOLDER`
