Karazeh

NOTE

You are currently reading the documentation for the master branch which is NOT stable and is not yet ready for production use. Refer to the stable branch if that's what you're looking for.

Karazeh is a cross-platform tool for patching and launching desktop applications, suited for PC games. The purpose of this tool is to provide you with the ability to update your users' clients with minimal hassle without requiring you to re-invent the wheel and write your own patcher.

Karazeh is meant to be used with Kiwi, the tool that generates the patch scripts which Karazeh consumes. They both should operate on Windows, Linux, and Mac OS X.

Both tools are freely available and licensed under the MIT license.

Building

See the [[./doc/building.md]] guide.

Usage

Currently there's a basic example you can see under examples/basic which shows how to interface with the low-level APIs to get an application to fetch the available updates and apply them in succession. However, it's likely we'll be introducing higher level APIs to do this sort of thing in the future so you wouldn't have to fret with so much details.

TBD

Tests

To run the unit tests you must launch an http server on port 9393 to serve the files under /path/to/karazeh/test/fixture for the tests.

If you have Python2 available, it's very easy:

(cd test/fixture; python2 -m SimpleHTTPServer 9393)

If you're on Arch Linux, you can use darkhttpd instead:

pacman -S darkhttpd
darkhttpd /path/to/karazeh/test/fixture --port 9393

Afterwards, run the binary:

./build/karazeh_tests

The test runner can be customized using some environment variables:

  • VERBOSE=1 if you want more output
  • ROOT=/path/to/root should point to the root directory of the Karazeh repository; this is needed in case the built-in binary locators aren't doing their job correctly.
  • HOST=http://customhost:1234 should point to the fixture server. Defaults to http://localhost:9393
