Attributes

Talos provides support for a selection of compile-time attributes. These allow annotating target declarations with metadata and functionality to empower development and runtime capabilities.

Deprecations

Variable declarations can now be noted as deprecated and any usage of these variables will be hinted as such (see the linting command for restricting deprecation usage).

// Annotating a variable as being deprecated.
#[Deprecated "This value is deprecated and will be removed in a future release"]
let value = ...;

// In a code-editor with a compatible Talos language-server, any usage of `value` will now be noted as deprecated.
Debug.println(value); 

Operator Hooks

Although limited, some operators can be added/altered to provide custom functionality. The operators that currently allow being defined include:

• dispose  —  Utilized by explicit resource management.
• iterator  —  Allows defining custom object iterators.

Additional Support

As language features are updated and improved, there may be additional attributes that are implemented for Talos.
