File Path Attribute

FilePath is used on string properties, and provides an interface for file paths.

// By default, FolderPath provides a path relative to the Unity project.
[FilePath]
public string UnityProjectPath;

// It is possible to provide custom parent path. Parent paths can be relative to the Unity project, or absolute.
[FilePath(ParentFolder = "Assets/Plugins/Sirenix")]
public string RelativeToParentPath;

// Using parent path, FilePath can also provide a path relative to a resources folder.
[FilePath(ParentFolder = "Assets/Resources")]
public string ResourcePath;

// Provide a comma seperated list of allowed extensions. Dots are optional.
[FilePath(Extensions = "cs")]
[BoxGroup("Conditions")]
public string ScriptFiles;

// By setting AbsolutePath to true, the FilePath will provide an absolute path instead.
[FilePath(AbsolutePath = true)]
[BoxGroup("Conditions")]
public string AbsolutePath;

// FilePath can also be configured to show an error, if the provided path is invalid.
[FilePath(RequireExistingPath = true)]
[BoxGroup("Conditions")]
public string ExistingPath;

// By default, FilePath will enforce the use of forward slashes. It can also be configured to use backslashes instead.
[FilePath(UseBackslashes = true)]
[BoxGroup("Conditions")]
public string Backslashes;

// FilePath also supports member references with the $ symbol.
[FilePath(ParentFolder = "$DynamicParent", Extensions = "$DynamicExtensions")]
[BoxGroup("Member referencing")]
public string DynamicFilePath;

[BoxGroup("Member referencing")]
public string DynamicParent = "Assets/Plugin/Sirenix";

[BoxGroup("Member referencing")]
public string DynamicExtensions = "cs, unity, jpg";

// FilePath also supports lists and arrays.
[FilePath(ParentFolder = "Assets/Plugins/Sirenix/Demos/Odin Inspector")]
[BoxGroup("Lists")]
public string[] ListOfFiles;
