I learned about most of the Java techniques and APIs used in this during development, so many things won't be designed ideally. I also never released such a project as opensource before, so if I missed anything or didn't adhere to some license correctly, please tell me.

Contributions

Contributions to Chatty under the terms of the GPLv3 License (or compatible) are welcome.

If you're contributing code that you didn't write yourself, make sure to adhere to whatever license terms it is under (like retaining copyright notices) and to detail that in the Pull Request.

Obviously, I won't be able to accept all contributions, for example I may already be working on something similar. If you plan to put more than a little effort into a Pull Request, consider asking first if what you're doing has a chance of being added.

Notes on building the program yourself

The project is compiled using Gradle. Once you've checked it out, you can run gradlew build to compile and run the tests, and gradlew release to package the release artifacts.

If you modified Chatty you should set your own client id in Chatty.java. You may also want to disable the Version Checker.

Main release tasks

• release - Just the regular JAR version Zip
• releaseWindows - Regular and Windows Standalone Zip
• releaseWinSetups - Everything, including Windows Standalone and Windows setups

Build parameters

• Windows Standalone (one of these required for the Windows Standalone tasks)
  • javapackagerPath - Path to the javapackager.exe in the Java 8 JDK
    • jrePath - Adds -Bruntime= option for javapackager (optional, will use default JRE otherwise)
  • jpackagePath - Path to the jpackage.exe in the Java 14+ JDK (if you specify this one, it will use jpackage instead of javapackager)
  • mtPath - Path to Microsoft's mt.exe (see e.g. https://stackoverflow.com/questions/54462568/how-to-install-just-mt-exe), used to add assets-bundle/Chatty.exe.manifest to the Chatty.exe/ ChattyPortable.exe (optional)
• innosetupPath - Path to InnoSetup's iscc.exe (required for the Windows installer tasks)

These build parameters must be specified like this: gradlew windowsZip -PjavapackagerPath="<path_to>/javapackager.exe"

Full example: gradlew -Dorg.gradle.java.home="C:/Program Files (x86)/Java/jdk1.8.0_201" releaseWinSetups --console=verbose -PjavapackagerPath="C:/Program Files (x86)/Java/jdk1.8.0_201/bin/javapackager.exe" -PjrePath="C:\Program Files (x86)\Java\jre1.8.0_201" -PinnosetupPath="C:\Program Files (x86)\Inno Setup 6\ISCC.exe"
