Examples

Here is how to run IronPython script using ScriptRun from the C# code:

public partial class Form1 : Form
{
    private void Form1_Load(object sender, EventArgs e)
    {
        var scriptRun = new Alternet.Scripter.IronPython.ScriptRun();
        scriptRun.ScriptSource.FromScriptFile(@"c:\myscript.py");
        scriptRun.Run();
    }
}

Here is how to run IronPython script using ScriptRun from the Visual Basic code:

Partial Public Class Form1
    Inherits Form

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim scriptRun = New Alternet.Scripter.IronPython.ScriptRun()
        scriptRun.ScriptSource.FromScriptFile("c:\myscript.py")
        scriptRun.Run()
    End Sub
End Class

Remarks

ScriptRun is a non-visual component that allows executing IronPython scripts and script projects. It allows referencing third-party assemblies and registering application-defined objects to be accessible in the scripts.

The most important properties and methods of the ScriptRun are:

The ScriptHost property provides properties and methods of the underlying scripting engine.

The ScriptSource property contains the source of the script to execute.

The GlobalItems property contains a collection of application objects accessible to the scripts.

The Run() method executes the script.

The RunFunction method executes the specified script function.

Constructors

ScriptRun(): Initializes a new instance of the ScriptRun class with default settings.

ScriptRun(IContainer): Initializes a new instance of the ScriptRun class with specified parameters.

Properties

AutoGenerateTypeDefinitions: Gets or sets whether project should automatically generate type definitions if possible.

CaseSensitive: When implemented by a class, indicates whether script language is case sensitive.

CodeEnvironment

Compiled: Gets boolean value indicating that script has been compiled and ready to be executed.

Executed: Gets boolean value indicating that script has been compiled and ready to be executed.

GlobalItems: Gets or sets a script items collection attached to this runner.

LoadUserTypeDefinitions: Gets or sets whether users type definitions should be loaded.

ProjectDirectory: Gets or sets root project directory.

ScriptHost: Returns object that implements IScriptHost interface for this runner.

ScriptSource: Gets source of the script to execute.

TypeDefinitionsSearchPaths: Gets or sets a list of search directories to look for type definitions.

Methods

Compile(): Initializes script engine and compiles the script.

CreateScriptHost(): Creates a new IScriptHost object with appropriate characteristics.

CreateScriptSource()

Dispose(bool)

EvaluateExpression(string): Evaluates specified expression.

EvaluateExpressionAsync(string, CancellationToken): Evaluates specified expression asynchronously.

LoadScript(string): Load script from specified file.

OnFileLoad(string): Invokes FileLoad event handler.

OnResolveReference(string, out string): Invokes ReferenceResolve event handler.

OnScriptError(ScriptErrorEventArgs): Invokes ScriptError event handler.

OnScriptExecuted(): Invokes ScriptRunning event handler.

OnScriptReset(): Invokes ScriptReset event handler.

OnScriptRunning(): Invokes ScriptRunning event handler.

Reset(): Resets the script engine and releases all resources.

Run(): Executes script starting from the main entry point.

RunAsync(CancellationToken): Executes script asynchronously starting from the main entry point.

RunFunction(string, object[]): Executes specified function.

RunFunctionAsync(string, object[], CancellationToken): Executes specified function asynchronously.

RunProcess(string[], bool): Executes script starting from the main entry point in stand-alone process

Events

FileLoad: Occurs when script code is loaded from file.

ReferenceResolve: Occurs when assembly reference needs to be resolved.

ScriptCompiled: Occurs when the script engine running successfully.

ScriptError: Occurs when the script engine running is failed.

ScriptExecuted: Occurs when script engine executes the script.

ScriptReset: Occurs when the script engine is reset.

ScriptRunning: Occurs when script engine tries to running script.
