Dyon - a rusty dynamically typed scripting language

Tutorial

If you want to say thanks for Dyon, or you found any of these ideas inspiring, please donate a small amount of money as a symbolic gesture to PayPal post at cutoutpro.com. Write a sentence describing why you think this is a good language and what you want to achieve. I (bvssvni, creator of Dyon) appreciate grateful and heart-warming responses!

Re-exports

• pub use ast::Lazy;
• pub use runtime::Runtime;

Modules

• ast
  Dyon Abstract Syntax Tree (AST).
• embed
  Traits for Dyon interop.
• macros
  Dyon macros.
• runtime
  Dyon runtime.

Macros

• dyon_fn
  Used to declare an embedded/external function in Rust which can be called from Dyon.
• dyon_fn_pop
  This macro is used by some other Dyon macros.
• dyon_macro_items
  This macro is used by some other Dyon macros.
• dyon_obj
  Used to implement embed::PopVariable and embed::PushVariable for some object.

Structs

• Call
  Used to call specific functions with arguments.
• ClosureEnvironment
  Stores closure environment.
• Dfn
  Stores preloaded function constraints. These are already checked.
• Error
  Stores Dyon errors.
• FnBinOpRef
  Used to store direct reference to external function.
• FnReturnRef
  Used to store direct reference to external function.
• FnUnOpRef
  Used to store direct reference to external function.
• FnVoidRef
  Used to store direct reference to external function that does not return anything.
• Link
  Stores a link structure.
• Mat4
  Wraps a 4D matrix for easier embedding with Dyon.
• Module
  Stores functions for a Dyon module.
• Prelude
  Stores a prelude, used to load standard intrinsics and type check new modules.
• Thread
  Stores a thread handle.
• UnsafeRef
  Prevents unsafe references from being accessed outside library.
• Vec4
  Wraps a 4D vector for easier embedding with Dyon.

Enums

• FnExt
  Refers to an external function.
• FnIndex
  Refers to a function.
• Lt
  Argument lifetime constraint.
• Type
  Stores a Dyon type.
• Variable
  Dyon variable.

Constants

• CSIE
  A common error message when the call stack is empty.
• TINVOTS
  A common error message when there is no value on the stack.

Statics

• LAZY_AND
  Lazy invariant for &&.
• LAZY_NO
  Lazy invariant that no arguments have lazy invariants.
• LAZY_OR
  Lazy invariant for ||.
• LAZY_UNWRAP_OR
  Lazy invariant to unwrap first argument.

Functions

• error
  Reports and error to standard output.
• load
  Loads source from file.
• load_meta
  Loads a source from meta data. Assumes the source passes the lifetime checker.
• load_str
  Loads a source from string.
• run
  Runs a program using a source file.
• run_str
  Runs a program from a string.

Type Aliases

• Array
  Type alias for Dyon arrays.
• LazyInvariant
  Type alias for lazy invariants of external functions.
• Object
  Type alias for Dyon objects.
• RustObject
  Type alias for Rust objects.
