  • _designer_version: The current version of Designer.
  • _alteryx_install_dir: The path to the installation directory of the Designer executable.
  • _workflow_dir: The path to the directory the current workflow is in.
  • _temp_dir: The path to the temp directory where runtime data is stored.
  • _tool_id: The ID of the tool.
  • _workflow_id: The ID of the current workflow.
  • _raw_constants: The rest of the data sent by the engine in its raw format:
    • AdditionalAliasFile
    • AlteryxExecutable: The path to the Designer executable.
    • CallerProductId: The ID of the caller.
    • ConvErrorLimit: The amount of conversion errors the engine can encounter before stopping.
    • DefaultDir: The default directory for Designer.
    • DefaultTempDir: The default directory for Designer to write temp files to.
    • DisableAllOutput: Indicates whether output from Designer has been disabled.
    • DisableBrowse: Indicates whether browse everywhere has been disabled.
    • EnablePerformanceProfiling: Indicates whether performance profiling has been enabled.
    • Engine.GuiInteraction: Indicates whether the workflow is being run from the GUI.
    • Engine.IterationNumber: The number of times a macro has run.
    • Engine.ModuleDirectory: The location where the engine module is located.
    • Engine.OS: The OS Designer is running on.
    • Engine.ReportFont: The font the engine reports are written in.
    • Engine.TempFilePath: The path where the engine writes temp files.
    • Engine.Type: The type of engine designer runs on.
    • Engine.Version: The version of the engine Designer uses.
    • Engine.WorkflowDirectory: The directory of the current workflow.
    • Engine.WorkflowFileName: The file name of the workflow (this is only available if the workflow has been saved).
    • GlobalRecordLimit: The maximum amount of records Designer can process.
    • JupyterTempPath: The temp path Jupyter writes to.
    • ModuleDirectory: The directory Designer module is stored in.
    • OutputConnectionMetaDataMessages: Indicates whether output connection metadata messages are enabled.
    • PredictiveCodePage
    • ProxyConfiguration: Used to proxy network requests.
    • RestrictedDataMode
    • RunMode: Indicates how the engine interacts with Designer.
    • SerialNumber: The serial number for Designer.
    • SortedGrouping
    • TempPath: The path where Designer writes temp files.
    • ToolId: The ID of the current tool.
    • UpdateOnly
    • UseVfs
    • WorkflowDirectory: The directory of the current workflow.
    • WorkflowRunGuid: The GUID of the current workflow run.


To access the constants, run this command:

def __init__(self, provider)
    desired_constant = self.provider.environment.*constant*

To access the constants stored in the _raw_constants, run this command:

def __init__(self, provider)
    desired_constant = self.provider.environment._raw_constants[*constant*]
