Cx == A scripting language for fun and profit.
``` cpp use io; // Standard IO io.puts("Hello, World!"); ``` Intro -- The Cx language is designed to be a very simple subset of C++ and C#. What makes Cx unique is the ability to easy extend the language using C++, and Cx. Basic data types can also be extended to add functionality. All data types can be extended by additional class declarations. This makes it easy to define objects in C++ to later extend those objects in Cx without having to recompile the library. For example, the below code will add the function is_digit to the basic Cx char type. ``` cpp class char { /*!is_digit - Check if character is decimal digit Checks whether "this" is a decimal digit character. Decimal digits are any of: 0 1 2 3 4 5 6 7 8 9 @param this : char to test if digit. @return true if digit, false if not. */ bool is_digit() { return ((this >= '0') && (this <= '9')); } } ``` The added function can then be called as follows: ``` cpp char c = '5'; if(c.is_digit) // true else // false ``` The Cx Virtual Machine (CxVM) -- The Cx back-end is a very simple op-code, stack-based processor built from scratch which (very) loosely follows the JVM instruction syntax. CxVM instructions can be directly emitted from within Cx source. ``` cpp int assembly_example(int i){ int a; asm iconst 0x3E8; // Load 1000 asm istore a; // a = 1000 asm{ iconst 0b11111111 // Load 255 iload a // Load 1000 (a == 1000) iadd // a + 255 = 1255 iload i // Load 100 (if i == 100) iadd // 1255 + 100 = 1355 istore i // i = 1355 iload i // Load 1355 istore assembly_example // assembly_example = 1355 ret // return } } // Returns 1355 to the OS return assembly_example(100); ``` Supported Compilers and Platforms -- ##### 32bit and 64bit Popular compilers which support C++11 are used to build the Cx interpreter. * clang++ * g++4.7 or later * VS 2012 express Cx language features are restricted to the C++11 standard library and will compile on OSX, Linux, and Windows. Any features deemed platform specific will be implemented in dynamic libraries which can be loaded at run-time. ### Cx Documentation All documentation will be posted and updated at the link below. More information may be found in Cx/doc * [Cx-doc](https://github.com/ahebert/cx/wiki) #### Influences * [Writing Compilers and Interpreters 2nd Edition](http://www.amazon.com/dp/0471113530/ref=cm_sw_r_tw_dp_Trazwb07Z6NRP) * [The Java Virtual Machine Specification](https://docs.oracle.com/javase/specs/jvms/se7/html/) ### Status This project is for educational purposes only and is still in early development. A working prototype is well underway and current work is focused on the base language.
