Kode Studio 16.1 was just released, a fork of the Visual Studio Code editor specifically modified to work with the Kha library for Haxe. Eventually Kode Studio should be useful as an IDE for general Haxe development... maybe, read on for more on this.
From the release notes:
To get started with Kode Studio, just unzip the archive, start the executable and open a directory (File -> Open Folder) containing a Kha project - or open an empty folder and hit the "Init Kha Project" command (Press F1, type Kha, click it).
To debug open the debugging panel (the bottom icon on the very left) and click the green play button.
Code completion will work after your first debugging session.
We hope you will enjoy developing in Kode Studio but as mentioned before, this is a very early release. Please tell us about any problems you encounter.
Oh and here are the answers to the questions everybody wants to ask:
Is the fork necessary? Couldn't it be an extension?
Currently it could be an extension for the most part, there are about 20 lines of code outside of extensions right now. But that is not were Kode Studio is headed. All functionality of Kit (Kha's previous GUI tool) will be integrated. The IDE will be tightly coupled to Kha's and Kore's build systems. Much of that can not be done in extensions. VSCode is a strong base but it's also a cage that has to be blast open to do Kha justice.
Is this a general Haxe IDE?
Right now - no. In the future - probably yes. But will it be a better Haxe IDE than VSCode plus the proper extensions? Probably not. The focus is clearly on Kha and Kore for Kode Studio. Every change done to the VSCode Haxe plugins that's not specific to Kha will end up in pull-requests for the original projects - namelyhttps://github.com/jcward/vscode-haxe andhttps://github.com/jcward/vscode-hxcpp-debug
