CX Programming Language

[Back to the Table of Contents] ↑

CX is a general purpose, interpreted and compiled programming language, with a very strict type system and a syntax similar to Golang's. CX provides a new programming paradigm based on the concept of affordances, where the user can ask the programming language at runtime what can be done with a CX object (functions, expressions, packages, etc.), and interactively or automatically choose one of the affordances to be applied. This paradigm has the main objective of providing an additional security layer for decentralized, blockchain-based applications, but can also be used for general purpose programming.

Installation

CX requires a Golang version of 1.15 or higher.

Binary Releases

You can find binary releases for most major systems on the release page.

Compiling on Linux

If you are using a apt compatible system, install the dependencies with"

sudo apt-get update -qq

sudo apt-get install -y glade xvfb libxinerama-dev libxcursor-dev libxrandr-dev libgl1-mesa-dev libxi-dev libperl-dev libcairo2-dev libpango1.0-dev libglib2.0-dev libopenal-dev libxxf86vm-dev --no-install-recommends

Download CX's repository using Go:

go get github.com/skycoin/cx

Get required Go dependencies with:

go get -u golang.org/x/mobile/cmd/gomobile
go get -u modernc.org/goyacc
go get golang.org/x/mobile/gl 

Navigate to CX's repository via:

cd $GOPATH/src/github.com/skycoin/cx

Build CX's binary and install by running:

make install

make install builds a CX binary and installs it into $HOME/cx/bin. Add the CX binary path to your operating system's $PATH. For example, in Linux:

export PATH=$PATH:$HOME/cx/bin

You should test your installation by running:

make test

If you intend to develop games with CX, then run:

make test-full

Compiling on MacOS

Download CX's repository using Go:

go get github.com/skycoin/cx

Navigate to CX's repository via:

cd $GOPATH/src/github.com/skycoin/cx

Build CX's binary and install by running:

make install

make install builds a CX binary and installs it into $HOME/cx/bin. Add the CX binary path to your operating system's $PATH. For example, in Linux:

export PATH=$PATH:$HOME/cx/bin

You should test your installation by running:

make test

If you intend to develop games with CX, then run:

make test-full

Compiling CX on Windows

Compiling CX on Windows requires a recent version of Git to be installed.

Before compiling CX, install dependencies with pacman:

pacman -Sy

pacman -S mingw-w64-x86_64-openal

if [ ! -a /mingw64/lib/libOpenAL32.a ]; then ln -s /mingw64/lib/libopenal.a /mingw64/lib/libOpenAL32.a; fi

if [ ! -a /mingw64/lib/libOpenAL32.dll.a ]; then ln -s /mingw64/lib/libopenal.dll.a /mingw64/lib/libOpenAL32.dll.a; fi

You can compile CX by running:

cx-setup.bat

Test your installation by running:

cx lib/args.cx tests/main.cx ++wdir=tests ++disable-tests=issue

Updating CX

You can update your CX installation by running:

make install

Or on Windows:

cx-setup.bat

Resources and libraries

If you are interested in learning more about CX, please refer to the resources documentation.

If you want to get started with some basic example programs and tutorials check out the tutorials section.

The docs also provide a high level overview over the language.
