# SimpleLang Interpreter

This is a command line interpreter for a simple, Turing complete, programming language. It can run code from a file or from the command line (interactive mode).

SimpleLang is actually a rebranding of a popular esoteric programming language called brain\. SimpleLang is just a change in name and nothing more, since I didn't want to plaster cuss words all over my online portfolio. Similarly, SimpleLang++ is a rebranding of a lesser known addition to the original language by Jacob I. Torrey. Both languages can be easily found on https://esolangs.org

SimpleLang is an esoteric programming language in which there are only 8 operations, these are as follows:

Operation | Explanation

:---: | :---

< | Decrements the data pointer  

\> | Increments the data pointer  

\- | Decrements the byte at the data pointer  

\+ | Increments the byte at the data pointer  

\[ | Begins a loop, if byte at data pointer is 0, skip to the command after end of loop  

\] | Jump to beginning of loop  

\, | Take a single byte of input  

\. | Print a the byte at the data pointer  

Anything that is not one of the above 8 operations is ignored, and can be used to comment.

# SimpleLang++ Interpreter 

SimpleLang++ is an addition to SimpleLang, which adds some new operations to extend the usefulness (if it was useful to begin with) and possibilities of the language.

The added operations in the SimpleLang++ language are:

Operation | Explanation

:---: | :---

\# |	Open a file for reading/writing

; |	write the character in the current cell to the file, overwriting what is in the file

: |	Read a character from the file

% |	Opens a socket for reading/writing. A second call closes the socket.

^ |	Sends the character in the current cell

! |	Reads a character from socket into current cell

The comment syntax does not change. Any SimpleLang program can be run using SimpleLang++, so long as none of the comments contain any of the new operations.  

The actual specification for the SimpleLang++ language (includes how to open files and sockets in more depth) can be found in spec.txt

# Building

To build the interpreter use **gcc main.c SimpleLang.c SimpleLangpp.c -o SimpleLang -Werror -Wall -lws2_32** on Windows platforms (using MinGW) and **gcc main.c SimpleLang.c SimpleLangpp.c -o SimpleLang -Werror -Wall** on linux/unix platforms.
