The THP programming language

THP is a statically typed, compiled programming language. Compiles to its own bytecode format, and runs on its own VM.

There is documentation and a WIP spec at https://thp-lang.org.

Install

This program depends on the zig stdlib and thpvm, the virtual machine target.

To run from source:

• Install the Zig programming language.
• Run zig build run to run the debug build
• Run zig build -Doptimize=ReleaseFast to build the final binary
• The binary will be located at zig-out/bin/thp
• Profit

Usage

Run thp --help to see usage.

Write source code

As of v0.0.5 the compiler is able to do:

• Basic u64 arithmetic
• Print strings
• Declare & use variables

var name = "John"
print("Hello, " + name + "!")

Compile to file

Run zig build run -- c /path/to/thp/source/code > out, where out is the file to write the bytecode to. The compiler always writes to stdout.

Run bytecode

See the thpvm package.

Compile & run in one command

Run zig build run -- run /path/to/thp/source/code. It will compile & run the code in one command.

Naming conventions

• When importing modules, use m_<module-name>: const m_parser = @import("./parser.zig");
• Variables that hold a token have a tok_ prefix: const tok_number = ...
• Variables that hold a type have a t_ prefix: const t_number = ...
• Inside structs, the reference to self is always named self, and a helper const is created: const Self = @This();
