# GenerateYarnFileWithDeclarations(IEnumerable\<Yarn.Compiler.Declaration>,string,IEnumerable\<string>?,IDictionary\<string, string>?)

Method in [Utility](/api/csharp/yarn.compiler/yarn.compiler.utility.md)

## Summary

Generates a Yarn script that contains a node that declares variables.

```csharp
public static string GenerateYarnFileWithDeclarations(IEnumerable<Yarn.Compiler.Declaration> declarations, string title = "Program", IEnumerable<string>? tags = null, IDictionary<string, string>? headers = null)
```

## Remarks

This method is intended to be called by tools that let the user manage variable declarations. Such tools can read the existing variable declarations in from a script (by compiling the script with the [CompilationType](/api/csharp/yarn.compiler/yarn.compiler.compilationjob/yarn.compiler.compilationjob.compilationtype.md) value set to [TypeCheck](/api/csharp/yarn.compiler/yarn.compiler.compilationjob/yarn.compiler.compilationjob.type/yarn.compiler.compilationjob.type.typecheck.md) ), allow the user to make changes, and then write the changes to disk by calling this method and saving the results.

## Parameters

| Name                                                                             | Description                                                                                                                              |
| -------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- |
| `System.Collections.Generic.IEnumerable<Yarn.Compiler.Declaration>` declarations | The collection of [Declaration](/api/csharp/yarn.compiler/yarn.compiler.declaration.md) objects to include in the output.                |
| `string` title                                                                   | The title of the node that should be generated.                                                                                          |
| `System.Collections.Generic.IEnumerable<string>` tags                            | The collection of tags that should be generated for the node. If this is `null` , no tags will be generated.                             |
| `System.Collections.Generic.IDictionary<string, string>` headers                 | The collection of additional headers that should be generated for the node. If this is `null` , no additional headers will be generated. |

## Returns

A string containing a Yarn script that declares the specified variables.
