Ymir is a high-level, statically typed programming language designed to help developers to save time by providing strong and safe semantic. The semantic of this language is oriented towards safety, concurrency and speed of execution. These objectives are achieved thanks to its high expressiveness and its direct compilation into an efficient native machine language.

This documentation explores the main concepts of Ymir, providing a set of examples that demonstrate the strengths of this new language. It also presents an introduction to the standard library.

Before starting to discuss the language, please keep in mind that it is still under development and that sometimes things may not work as expected. If you encounter errors that you do not understand or think are incorrect, please contact us at: gnu.ymir@mail.com. We look forward to receiving your mails!

Even more, all contributions are very welcome, whether to improve the documentation, to propose improvements to the language or std, to the runtime, or even to the automatic release generation procedure. All code repositories are available on github. In this documentation, known limitations of the language are sometimes highlighted, and calls for contribution.

The reference compiler of Ymir is based on the compiler GCC, which offer strong static optimization, as well as a vast set of supported target architectures.

This compiler can be installed on linux debian system, by following those simple steps:

• First, you need to download the package :
  • gyc-11

Other gyc versions using other gcc backend versions are available at release.

• And then, you need to install it using dpkg :

$ sudo dpkg -i gyc-11_11.3.0_amd64.deb

This package depends on :

• g++-11
• gcc-11
• libgc-dev

If one of them is not installed, you will get an error, that can be resolved by running the following command :

sudo apt --fix-broken install

And then reinstall the package that has previously failed (dpkg). The compiler is now installed and is named gyc

$ gyc --version
