Configuration

This extension adds the following Visual Studio Code settings. These can be set in user preferences (⌘+,) or workspace settings (.vscode/settings.json).

• hack.clientPath: Absolute path to the hh_client executable. This can be left empty if hh_client is already in your environment $PATH.

Issues

Please file all bugs, issues, feature requests etc. at the GitHub issues page.

Current known issues:

• (#1, Microsoft/vscode#10915) The editor may not select the Hack language mode for .php files even if they start with <?hh. To get around this, either manually select "Hack" as the file language from the selector on the bottom right of the screen, or configure your project workspace to open all .php files in Hack mode by adding the following to your workspace settings:

    "files.associations": {
        "*.php": "hack"
    }
