Here for eternal shame. Contains only "+" and "print" - nothing else, no functions are definable. Here for the shame in particular of those who gave it 125 stars, without having tried it for a second.

Cisp

A Common Lisp Interpreter Built in COBOL.

Overview

Purpose

This is a small project built by a student at the Recurse Center to express a love for COBOL and better understand it.

Due to COBOL's lack of functions and recursion, the recursion required for Lisp is built from the ground up using file processing. Also, due to the lack of a widely supported debugger, a system logger was also implemented.

Compatibility

Please note that Cisp is currently only actively developed for Windows. *Nix users may experience issues.

Functionality

All features are currently in development. This is a list of what is to come.

Representation of Symbols and Numbers
Basic Arithmetic
Flow-Control Statements
Lists

Notes

The README much like the entire project is in current development.

Running Cisp

Hello World

Make a subdirectory for your lisp file.

mkdir test\helloworld

Create a new file helloworld.lisp in your subdirectory containing the following:

(print "HelloWorld!")

To run Cisp cd into the bin (Note that you must cd in)

cd bin

Run Cisp

cisp.exe ..\test\helloworld\helloworld.lisp

Project Structure

Currently the COBOL source files are located in the root directory.

Directories

bin - Contains all necessary *.dll's (windows users) for those who want to play with CISP without changing the code. This is due to the fact that so few people have COBOL compilers.
logs - Contains the log file generated by the system.
test - Contains all test files organized by subject.

COBOL Files

cisp.cbl - The main COBOL program.
cisp-error.cbl - The Error System in the program. It will "throw" errors when called.
lisp.cbl - Responsible for executing the lisp program.
logger.cbl - The Logging System in the program. It will log events in the system when called.
recursion.cbl - Handles recursion as requested from lisp.cbl.
tokenizer.cbl - Responsible for tokenizing the lisp file given to execute.

Compiling

The easiest way I have found to compile COBOL is GNU's COBOL compilier. For those who prefer IDE's I have found Open COBOL IDE to be very helpful.

Running Tests

Windows

To run all tests in the project, double click bin\cisp.bat

To run a single test: cd bin

cisp.exe ..\test\test_subdirectory\test_name.lisp

Create your own Lisp Files for Testing

Create a directory in test\ to create another test category.
In your subdirectory create a lisp file.
cd bin
cisp.exe ..\test\test_subdirectory\test_name.lisp

Linux

Instructions yet to come. The author is a window's user, and *nix systems are not currently supported.

A high level overview is to compile the project and run the executable in the bin folder.
