This extension provides:

• Syntax highlighting for .hx and .hxml files
• Code completion (work in progress)
• Function signature completion
• Jump / peek definition (ctrl-click / ctrl-hover)

#Install the Extension

For the stable version of this plugin, it is availble in the VSCode Marketplace. From within VSCode, press F1, type ext install and press enter, type haxe and it will be listed under publisher Haxe Devs.

For development versions, place the vscode-haxe directory in your .vscode/extensions directory:

• Windows: %USERPROFILE%\.vscode\extensions
• Linux / Mac: ~/.vscode/extensions

#Project setup

Code completion and other features require an .hxml file in your project. Various frameworks (OpenFL, Snow, Kha, etc) can generate the .hxml file for you -- see the Framework notes section below.

By default the extension looks for a build.hxml in the root of the project, but you can set the location in your project's settings under File -> Preferences -> Workspace Settings. Add the following setting locating your .hxml file relative to the project directory:

{
    "haxe.haxeDefaultBuildFile": "path/to/build.hxml"
}

#Framework notes: Some frameworks support the creation of .hxml files, which is necessary to run the Haxe code completion engine. Below is a list of how you can get an .hxml file from various frameworks.

Feel free to file an issue with details for other frameworks.

#Other notes and status

##Code completion status: BETA The code completion in this extension is currently in beta. There are bugs, limitations, and requirements that still need to be worked out. There's an effort to standardize Haxe IDE support over at snowkit/Tides. When this is ready, we'll integrate it (no need to duplicate effort and provide divergent experiences.)

##Current limitations: Some features may require a forthcoming version of the Haxe compiler.

##Troubleshooting the completion features You can start the haxe completion server by hand in verbose mode in a separate terminal. First, kill any existing Haxe completion servers, start it with haxe -v --wait 6000, and open your project in code. Here's an example in Linux:

>pkill haxe
>haxe -v --wait 6000

After starting my project, the console spits out the arguments and results of the completion server, e.g.:
