Tomo - Tomorrow's Language

Tomo is a statically typed, safe, simple, lightweight, efficient programming language that cross-compiles to C. Tomo is designed to anticipate and influence the language design decisions of the future.

func greeting(name:Text)->Text
	greeting := "hello {name}!"
	return greeting:title()

>> greeting("world")
= "Hello World!"

Features

Extremely high performance code generation with minimal overhead compared to C
Extremely fast parallel compilation times
Memory safety (garbage collection, compiler-enforced null safety, automatic array bounds checking, and no uninitialized variables)
Arithmetic overflow checking
Simple, low-boilerplate type system with type inference
Useful and efficient built-in types: arrays, hash tables, structs, tagged unions (sum types), cords (efficient string representation)
Well-defined reference and value semantics and mutability rules
Language-level support for out-of-the-box function caching emphasizing correctness
Type-safe strings representing different languages with automatic prevention of code injection
Full UTF8 support for both source code and standard library
Pattern matching with exhaustiveness checking for tagged unions
Beautiful and helpful compiler and runtime error messages with emphasis on user-friendliness
Structs with known-at-compile-time methods, not OOP objects with vtable lookups
Built-in doctests with syntax highlighting
Easy interoperability with C

Dependencies

Tomo has a very small set of dependencies:

The Boehm garbage collector for runtime garbage collection.
libunistring for unicode string support.
a C compiler
and libc/libm, which should definitely already be installed.

Both of which should be available on your package manager of choice (for example, pacman -S gc libunistring).

Building

The Tomo compiler can be compiled with either GCC or Clang by running make.

Running

You can run a Tomo program by running ./tomo program.tm. By default, this will use your environment's $CC variable to select which C compiler to use. If no C compiler is specified, it will default to tcc (Tiny C Compiler), which is exceptionally fast.

Installing

make && sudo make install
