Otterkit 1.0.50-alpha

Otterkit COBOL Compiler

Otterkit is a free and open source compiler for the COBOL Programming Language on the .NET platform.

Warning: The project is currently in pre-release, so not all of the standard has been implemented.

About

COBOL was created in 1959 by the CODASYL Committee (With Rear Admiral Grace Hopper as a technical consultant to the committee), its design follows Grace Hopper's belief that programs should be written in a language that is close to English. It prioritizes readability, reliability, and long-term maintenance. The language has been implemented throughout the decades on many platforms with many dialects. Otterkit COBOL is a free and open source compiler that aims to implement the ISO/IEC 1989:2023 COBOL Standard (COBOL 2023) on the .NET platform.

Installation

Quick Install

Otterkit is available to install on the Nuget package manager (.NET 7 is required). To install, type these two lines into the command line:

dotnet new install Otterkit.Templates::1.0.45-alpha

dotnet tool install --global Otterkit --version 1.0.45-alpha

Build from Source

First, clone the git repo from https://github.com/otterkit/otterkit.git to get the source code. To access the libotterkit submodule inside, use the --recurse-submodules --remote-submodules flag on the clone command. To run, navigate into the src folder (for the compiler, not libotterkit) and then type dotnet run into the command line.

Build from Source on MacOS (For Intel and Apple Silicon processors)

After clone the git repo navigate into the src folder and type:

dotnet run new app   

For build the COBOL file type:

dotnet run build -e ${COBOLFILEPATH} --free       

For build and run the COBOL file type:

dotnet run build --run -e ${COBOLFILEPATH} --free
