Creating the world's most complex "Hello world" program

Link All the Languages!

An ongoing project created by Alexander Hill where we link as many programming languages as possible into a single executable.

Theory

Most programming languages provide a foreign function interface to the C language. Therefore, language X should be able to call functions in language Y and language Y should be able to call functions in language X using the C ABI.

Languages

Tier 3 (Statically linked and fully interoperable)

• Assembly
• C
• C++
• Nim
• Zig

Tier 2 (Can call C and be called by C)

• D
• Lua
• Rust

Tier 1 (Can be called by C)

• Fortran
• Go
• Java
• Kotlin
• Python
• Rexx
• Ruby
• Tcl

To-do

• APL
• B
• Ballerina

• Crystal(crystal-lang/crystal#921)

Rules for including languages

1. Languages must be statically linked
2. Languages must be able to use their standard library
3. Languages must be able to call C and be called by C
4. Languages must be stable(1.0.0 or greater in semantic versioning)

Missing Christmas Messages

I noticed that both Carp and Zig don't check the month to print a special message. While this isn't the end of the world, it'd be nice to have. Can you two add a special message to your code?

• Added a Christmas message to Carp
• Added a Christmas message to Nim
• Added a Christmas message to Zig

Thanks in advance!

Custom Build System (Tracking Issue)

We are in the process of migrating from GNU Make to a custom build system.
We require the following features before we can safely deprecate our Makefile:

• Incremental Builds
• Parallel Builds

Once these have been implemented, a deprecation notice for the GNU Makefile shall be published.
After that, maintenance of the GNU Makefile shall end.
