nitlang / Nit

Nit is an expressive language with a script-like syntax, a friendly type-system and aims at elegance, simplicity and intuitiveness.

Nit has a simple straightforward style and can usually be picked up quickly, particularly by anyone who has programmed before. While object-oriented, it allows procedural styles.

The Nit Compiler (nitc) produces efficient machine language binaries.

Some Nit features:

• Pure Object-Oriented.
• Multiple Inheritance.
• Realist typing policy.
• Light and clear syntax.

Requirements:

• gcc http://gcc.gnu.org/ (or a compatible C compiler)
• pkg-config http://www.freedesktop.org/wiki/Software/pkg-config/
• ccache http://ccache.samba.org/ to improve recompilation
• libgc-dev http://hboehm.info/gc/
• libunwind http://nongnu.org/libunwind

Those are available in most Linux distributions

$ sudo apt-get install build-essential ccache libgc-dev libunwind-dev pkg-config

and on OS X using brew

$ brew install ccache bdw-gc libunwind-headers pkgconfig

or with MacPorts

$ sudo port install ccache boehmgc libunwind-headers pkgconfig

How to start:

$ make
$ bin/nitc examples/hello_world.nit
$ ./hello_world

You can source misc/nit_env.sh to setup your environment like PATH, MANPATH and bash completion. To have your environment automatically configured at login, just source it with install as argument.

$ . misc/nit_env.sh install

More tools:

Additional tools can also be compiled but require more dependencies.

• graphviz http://www.graphviz.org/ to enable graphs with the nitdoc tool

• libcurl https://curl.haxx.se/libcurl/ for the nit package manager nitpm

• libevent https://libevent.org/ for the nit documentation server nitweb

• libmongoc http://mongoc.org/ also for nitweb

  $ sudo apt-get install graphviz libcurl4-openssl-dev libevent-dev libmongoc-dev $ make more
