Versioning

This repo is versioned by .NET major:

• .NET 10 → versions/10/ → npm: @tsonic/core@10.x

When publishing, run: npm publish versions/10 --access public

Installation

Usage

import { int, float, bool } from "@tsonic/core/types.js";

const age: int = 42 as int;
const temp: float = 98.6 as float;
const isActive: bool = true;

Type Aliases

Signed Integer Types

• sbyte - System.SByte (-128 to 127)
• short - System.Int16 (-32,768 to 32,767)
• int - System.Int32 (-2,147,483,648 to 2,147,483,647)
• long - System.Int64
• nint - System.IntPtr (native int)
• int128 - System.Int128

Unsigned Integer Types

• byte - System.Byte (0 to 255)
• ushort - System.UInt16 (0 to 65,535)
• uint - System.UInt32 (0 to 4,294,967,295)
• ulong - System.UInt64
• nuint - System.UIntPtr (native uint)
• uint128 - System.UInt128

Floating-Point Types

• half - System.Half (16-bit float)
• float - System.Single (32-bit float)
• double - System.Double (64-bit float)
• decimal - System.Decimal (128-bit decimal)

Other Types

• bool - System.Boolean
• char - System.Char (single UTF-16 code unit)
• ptr<T> - C# unsafe pointer types

Important Notes

These are simple type aliases with NO runtime enforcement. TypeScript treats all numeric types as number, bool as boolean, etc.

Tsonic enforces semantic correctness at compile time via its proof system. TypeScript alone will NOT catch type errors between int/byte/long etc.
