Examples

Here is how to run TypeScript 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.TypeScript.ScriptRun();
        scriptRun.ScriptSource.FromScriptFile(@"c:\myscript.ts");
        scriptRun.Run();
    }
}

Here is how to run TypeScript 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.TypeScript.ScriptRun()
        scriptRun.ScriptSource.FromScriptFile("c:\myscript.ts")
        scriptRun.Run()
    End Sub
End Class

Remarks

ScriptRun is a non-visual component that allows executing JavaScript or TypeScript 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 and allows adding application-specific objects to the script.

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

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.

AutoGeneratedTypeDefinitionsPath: 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.

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

EmbeddedTypeDefitionsLocations: Gets or sets a collection of EmbeddedTypeDefitionsLocation that belong to the project.

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

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.

ScriptLanguage: Gets or sets programming language of the script.

ScriptSource: Gets source of the script to execute.

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

WaitForDebuggerOnStart: Gets of sets a boolean value indicates whether script engine is to wait for a debugger connection and schedule a pause before executing the first line of application script code.
