jStat - JavaScript Statistical Library

Build Prerequisites

In order to build jStat, you need to have GNU make 3.8 or later, Node.js 0.2 or later, and git 1.7 or later. (Earlier versions might work OK, but are not tested.)

Windows users have two options:

  1. Install msysgit (Full installer for official Git), GNU make for Windows, and a binary version of Node.js. Make sure all three packages are installed to the same location (by default, this is C:\Program Files\Git).
  2. Install Cygwin (make sure you install the git, make, and which packages), then either follow the Node.js build instructions or install the binary version of Node.js.

Mac OS users should install Xcode (comes on your Mac OS install DVD, or downloadable from Apple's Xcode site) and http://mxcl.github.com/homebrew/. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js.

Linux/BSD users should use their appropriate package managers to install make, git, and node, or build from source if you swing that way.

Building jStat

First, clone a copy of the jStat git repo by running git clone git://github.com/jstat/jstat.git.

To download all necessary libraries run npm install.

Then, to get a complete, minified version of jStat and all documentation, simply cd to the jstat directory and type make. If you don't have Node installed and/or want to make a basic, uncompressed, unlinted version of jstat, use make jstat instead of make.

The built version of jStat will be put in the dist/ subdirectory.

Generate just the documentation by running make doc. Documentation will be placed in dist/docs by default.

To remove all built files, run make clean.

Running Tests

Execute all tests by running make test.

Or if you wish to run a specific test, cd to test/<subdir> and run node <some_test>-test.js.

Get the Code

Both the minified and unminified source are located in the dist/ directory. For those who don't want to build it themselves.

Contribute

jStat is now going to follow most of the v8 JavaScript guidelines. There will be plenty of source that uses the old style, but we're going to work away from that.

Also, we'll be going through and reimplementing a good portion of the code to run faster. Hopefully it won't take too long to get the project on one basic standard.
