Package Exports

compute-dims

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (compute-dims) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

dims

Computes array dimensions.

Installation

$ npm install compute-dims

For use in the browser, use browserify.

Usage

To use the module,

var dims = require( 'compute-dims' );

dims( arr[, max] )

Computes array dimensions, including nested arrays.

var data, d;

data = [ 1, 2 ];
d = dims( data );
// returns [2]

data = [ [1,2], [1,2] ];
d = dims( data );
// returns [2,2]

If an array element has a dimension inconsistent with other elements, the function returns null.

data = [ [1,2], [1] ];
d = dims( data );
// returns null

To limit the number of dimensions returned, set the max option.

data = [ [[1,2], [3,4]] ]; // 1x2x2
d = dims( data, 2 );
// returns [1,2]

data = [ [[1,2], [3,4,5,6,7,8]] ];
d = dims( data );
// returns null

d = dims( data, 2 );
// returns [1,2]

Examples

To run the example code from the top-level application directory,

$ node ./examples/index.js

Tests

Unit

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov
